Figure 16 B depicts a comparison of HDV ribozymes (HDV68 and genomic HDV) and the Twister ribozyme (Twst). The Twister ribozyme located at the 3' end of Nt-Luc provided maximal luciferase activity, which was abolished by a catalytically inactive mutation (Twst mut). Figure 16 C depicts a comparison of Twister ribozyme sequence modifications. Shortening of the P1 stem reduces reporter gene activity. Modification of the first residue reveals that the Twister ribozyme can tolerate an A nucleotide at position 1 (U1A). DETAILED DESCRIPTION
[0042] definition
[0043] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
[0044] Generally, the nomenclature used herein and the laboratory procedures in cell culture, molecular genetics, organic chemistry, nucleic acid chemistry and hybridization are those well known and commonly used in the art.
[0045] Standard techniques are used for nucleic acid and peptide synthesis. The techniques and procedures are generally performed according to the conventional methods in the art and throughout the various general references provided herein (e.g., Sambrook and Russell, 2012, Molecular Cloning, A Laboratory Approach, Cold Spring Harbor Press, Cold Spring Harbor, NY, and Ausubel et al., 2012, Current Protocols in Molecular Biology, John Wiley & Sons, NY).
[0046] The nomenclature used herein and the laboratory procedures in analytical chemistry and organic syntheses described below are those well known and commonly employed in the art. Standard techniques or their modifications were used for chemical syntheses and chemical analyses.
[0047] The terms "a," "an," "the," and similar terms used in the context of the present invention (especially in the context of the claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context.
[0048] As used herein, "about" when referring to a measurable value such as an amount, duration, etc., is intended to encompass variations of ±20%, or ±10%, or ±5%, or ±1%, or ±0.1% of the specified value, as such variations are applicable to performing the disclosed methods.
[0049] "Antisense" refers specifically to a nucleic acid sequence of the non-coding strand of a double-stranded DNA molecule encoding a protein, or a sequence that is substantially homologous to the non-coding strand. As defined herein, an antisense sequence is complementary to the sequence of a double-stranded DNA molecule encoding a protein. An antisense sequence need not be complementary only to the coding portion of the coding strand of a DNA molecule. An antisense sequence can be complementary to a specified regulatory sequence on the coding strand of a DNA molecule encoding a protein, which regulatory sequence controls the expression of the coding sequence.
[0050] As used herein, the term "attached" when referring to the immobilization of a molecule (eg, a nucleic acid molecule) to a solid support is intended to encompass direct or indirect, covalent or non-covalent attachment, unless expressly or context indicates otherwise.
[0051] As used interchangeably herein, "microspheres," "beads," or grammatical equivalents thereof, describe small, discrete particles capable of serving as solid supports for the attachment of biomolecules (eg, nucleic acid molecules).
[0052] "Disease" is a health condition in an animal in which the animal cannot maintain homeostasis and in which, if the disease does not improve, the animal's health continues to deteriorate.
[0053] In contrast, a "disorder" in an animal is a state of health in which the animal is able to maintain homeostasis, but in which the animal's health is less than it would be in the absence of the disorder. If left untreated, the disorder does not necessarily result in a further decline in the animal's health.
[0054] A disease or condition is "relieved" if the severity of the signs or symptoms of the disease or condition, the frequency with which the patient experiences such signs or symptoms, or both, is reduced.
[0055] "Coding" refers to the inherent properties of a specific nucleotide sequence (such as a gene, cDNA or mRNA) in a polynucleotide, which is used to serve as a template for synthesizing other polymers and macromolecules with a determined nucleotide sequence (i.e., rRNA, tRNA and mRNA) or a determined amino acid sequence and the resulting biological properties in a biological process. Therefore, if the transcription and translation of the mRNA corresponding to a gene produce a protein in a cell or other biological system, the gene encodes a protein. Coding strand (its nucleotide sequence is identical to the mRNA sequence, and is generally provided in a sequence table) and non-coding strand (as a template for gene or cDNA transcription) can be referred to as encoding a protein or other product of the gene or cDNA.
[0056] The terms "patient," "subject," "individual," and the like are used interchangeably herein and refer to any animal or cell suitable for the methods described herein, whether in vitro or in vivo. In one embodiment, the subject includes vertebrates and invertebrates. Invertebrates include, but are not limited to, Drosophila melanogaster and Caenorhabditis elegans. Vertebrates include, but are not limited to, primates, rodents, domestic animals, or game animals. Primates include, but are not limited to, chimpanzees, crab-eating macaques, spider monkeys, and macaques (e.g., rhesus macaques). Rodents include, but are not limited to, mice, rats, marmots, ferrets, rabbits, and hamsters. Domestic animals and game animals include, but are not limited to, cattle, horses, pigs, deer, bison, buffaloes, feline species (e.g., house cats), canine species (e.g., dogs, foxes, wolves), bird species (e.g., chickens, emu, ostriches), and fish (e.g., zebrafish, trout, catfish, and salmon). In some embodiments, the subject is a mammal, such as a primate, such as a human. In certain non-limiting embodiments, the patient, subject, or individual is a human.
[0057] As used herein, the term "specifically binds" with respect to an antibody refers to an antibody that recognizes a specific antigen but does not substantially recognize or bind to other molecules in the sample. For example, an antibody that specifically binds to an antigen from one species may also bind to that antigen from one or more species. However, this cross-species reactivity itself does not change the specific classification of the antibody. In another example, an antibody that specifically binds to an antigen may also bind to different allelic forms of the antigen. However, this cross-reactivity itself does not change the specific classification of the antibody.
[0058] In some cases, the term "specific binding" or "specifically binds" may be used to refer to the interaction of an antibody, protein, or peptide with a second chemical substance to indicate that the interaction is dependent on a specific structure (e.g., an antigenic determinant or epitope) present on the chemical substance; for example, the antibody recognizes and binds to a specific protein structure, rather than proteins in general. If the antibody is specific for epitope "A," then in a reaction containing labeled "A" and the antibody, the presence of a molecule containing epitope A (or free, unlabeled A) will reduce the amount of labeled A bound to the antibody.
[0059] The "coding region" of a gene is composed of nucleotide residues of the coding strand of the gene and nucleotides of the non-coding strand of the gene that are homologous or complementary to the coding region of the mRNA molecule transcribed from the gene.
[0060] The "coding region" of an mRNA molecule also consists of the nucleotide residues of the mRNA molecule that match the anticodon region of the transfer RNA molecule or encode a stop codon during translation of the mRNA molecule. Thus, the coding region can include nucleotide residues that contain codons for amino acid residues that are not present in the mature protein encoded by the mRNA molecule (e.g., amino acid residues in a protein export signal sequence).
[0061] As used herein to refer to "complementarity" of nucleic acids, it refers to the broad concept of sequence complementarity between the regions of two nucleic acid chains or between two regions of the same nucleic acid chain. It is known that if the residue is thymine or uracil, the adenine residues of the first nucleic acid region can form specific hydrogen bonds ("base pairing") with the residues of the second nucleic acid region that is antiparallel to the first region. Similarly, it is known that the cytosine residues of the first nucleic acid chain can pair with the residues of the second nucleic acid chain, and if the residue is guanine, the second nucleic acid chain is antiparallel to the first chain. The first region of a nucleic acid is complementary to the second region of the same or different nucleic acids under the following circumstances: if when the two regions are arranged in an antiparallel manner, at least one nucleotide residue in the first region can pair with the residues in the second region. In one embodiment, the first region includes a first portion and the second region includes a second portion, whereby, when the first portion and the second portion are arranged in an antiparallel manner, at least about 50%, at least about 75%, at least about 90%, or at least about 95% of the nucleotide residues in the first portion can base pair with the nucleotide residues in the second portion. In one embodiment, all nucleotide residues in the first portion are capable of base pairing with nucleotide residues in the second portion.
[0062] The term "DNA" as used herein is defined as deoxyribonucleic acid.
[0063] The term "expression" as used herein is defined as the transcription and / or translation of a specific nucleotide sequence driven by its promoter.
[0064] As used herein, the term "expression vector" refers to a vector containing a nucleic acid sequence that encodes at least a portion of a gene product that can be transcribed. In some cases, the RNA molecule is then translated into a protein, polypeptide, or peptide. In other cases, these sequences are not translated, for example, in the production of antisense molecules, siRNA, ribozymes, etc. Expression vectors can contain a variety of control sequences, which refer to nucleic acid sequences necessary for the transcription and possible translation of an operably linked coding sequence in a specific host organism. In addition to control sequences for regulating transcription and translation, vectors and expression vectors can also contain nucleic acid sequences with other functions.
[0065] As used herein, the term "wild type" is a term understood by those skilled in the art and means the typical form of an organism, strain, gene or trait as found in nature, as distinguished from mutant or variant forms.
[0066] The term "homology" refers to a degree of complementarity. There may be partial homology or complete homology (i.e., identity). Homology is often measured using sequence analysis software (e.g., sequence analysis software packages from Genetics Computer Group. (University of Wisconsin Biotechnology Center. 1710 University Avenue. Madison, Wis. 53705)). Such software matches similar sequences by assigning degrees of homology to various substitutions, deletions, insertions, and other modifications. Conservative substitutions typically include substitutions within the following groups: glycine, alanine; valine, isoleucine, leucine; aspartic acid, glutamic acid, asparagine, glutamine; serine, threonine; lysine, arginine; and phenylalanine, tyrosine.
[0067] "Isolated" means altered or removed from its natural state. For example, a nucleic acid or peptide naturally present in the normal environment of a living animal is not "isolated," but the same nucleic acid or peptide partially or completely separated from the coexisting materials of its natural environment is "isolated." An isolated nucleic acid or protein can exist in a substantially purified form or can exist in a non-natural environment, such as a host cell.
[0068] The term "isolated" when used in relation to nucleic acids, such as "isolated oligonucleotide" or "isolated polynucleotide" refers to a nucleic acid sequence that has been identified and separated from at least one contaminant normally associated with its source. Thus, an isolated nucleic acid exists in a form or environment different from that in which it is found in nature. In contrast, non-isolated nucleic acids (e.g., DNA and RNA) are found in the state in which they exist in nature. For example, a given DNA sequence (e.g., a gene) is found adjacent to adjacent genes on a host cell chromosome; an RNA sequence (e.g., a specific mRNA sequence encoding a specific protein) is found in a cell as a mixture with many other mRNAs encoding numerous proteins. However, an isolated nucleic acid includes, for example, a nucleic acid in a cell that normally expresses the nucleic acid, that is located at a chromosomal location different from that of the natural cell, or that is otherwise flanked by a nucleic acid sequence different from that found in nature. An isolated nucleic acid or oligonucleotide can exist in single-stranded or double-stranded form. When isolated nucleic acids or oligonucleotides are used to express a protein, the oligonucleotide comprises at least the sense or coding strand (ie, the oligonucleotide can be single-stranded), but can comprise both sense and antisense strands (ie, the oligonucleotide can be double-stranded).
[0069] The term "isolated," when used in relation to a polypeptide, as in "isolated protein" or "isolated polypeptide," refers to a polypeptide that has been identified and separated from at least one contaminant normally associated with its source. Thus, an isolated polypeptide exists in a form or environment different from that in which it is found in nature. In contrast, non-isolated polypeptides (e.g., proteins and enzymes) are found in the state in which they occur in nature.
[0070] By "nucleic acid" is meant any nucleic acid, whether composed of deoxyribonucleosides or ribonucleosides, and whether composed of phosphodiester linkages or modified linkages such as phosphotriester, phosphoramidate, siloxane, carbonate, carboxymethyl ester, imidoacetate, carbamate, thioether, bridged phosphoramidate, bridged methylenephosphonate, phosphorothioate, methylphosphonate, phosphorodithioate, bridged phosphorothioate, or sulfone linkages, and combinations of such linkages. The term nucleic acid also specifically includes nucleic acids composed of bases other than the five biologically occurring bases (adenine, guanine, thymine, cytosine, and uracil). The term "nucleic acid" generally refers to large polynucleotides.
[0071] Conventional notation is used herein to describe polynucleotide sequences: the left-hand end of a single-stranded polynucleotide sequence is the 5' end; the left-hand direction of a double-stranded polynucleotide sequence is referred to as the 5' direction.
[0072] The direction in which nucleotides are added to the nascent RNA transcript, from 5' to 3', is called the direction of transcription. The DNA strand with the same sequence as the mRNA is called the "coding strand." The sequence on the DNA strand 5' from a reference point on the DNA is called the "upstream sequence," and the sequence on the DNA strand 3' from the reference point on the DNA is called the "downstream sequence."
[0073] "Expression cassette" means a nucleic acid molecule comprising a coding sequence operably linked to promoter / regulatory sequences required for the transcription and, optionally, translation of the coding sequence.
[0074] As used herein, the term "operably linked" refers to the linkage of nucleic acid sequences that results in a nucleic acid molecule capable of directing the transcription of a given gene and / or the synthesis of a desired protein molecule. The term also refers to the linkage of amino acid encoding sequences that results in a functional (e.g., enzymatically active, capable of binding to a binding partner, capable of inhibition, etc.) protein or polypeptide.
[0075] As used herein, the term "promoter / regulatory sequence" refers to a nucleic acid sequence required for expression of a gene product operably linked to the promoter / regulatory sequence. In some cases, the sequence may be a core promoter sequence, while in other cases, the sequence may also include an enhancer sequence and other regulatory elements required for expression of the gene product. The promoter / regulatory sequence may, for example, be a sequence that expresses a gene product in an inducible manner.
[0076] As used herein, "stringent conditions" for hybridization refer to conditions under which a nucleic acid having complementarity with a target sequence primarily hybridizes to the target sequence and substantially does not hybridize to non-target sequences. Stringent conditions are generally sequence-dependent and depend on many factors. Generally speaking, the longer the sequence, the higher the temperature at which the sequence specifically hybridizes to its target sequence. Non-limiting examples of stringent conditions are described in detail in Tijssen (1993), Laboratory Techniques In Biochemistry And Molecular Biology - Hybridization With Nucleic Acid Probes Part 1, Chapter 2 "Overview of principles of hybridization and the strategy of nucleic acid probe assay", Elsevier, NY.
[0077] "Hybridization" refers to the reaction of one or more polynucleotides to form a complex that is stabilized by hydrogen bonding between the bases of the nucleotide residues. This hydrogen bonding can occur by Watson Crick base pairing, Hoogstein binding, or in any other sequence-specific manner. The complex may include two chains that form a duplex structure, three or more chains that form a multi-chain complex, a single self-hybridizing chain, or any combination of these. A hybridization reaction can constitute a step in a broader process, such as the initiation of PCR, or the cleavage of a polynucleotide by an enzyme. A sequence that is capable of hybridizing to a given sequence is referred to as the "complementary sequence" of that given sequence.
[0078] An "inducible" promoter is a nucleotide sequence that, when operably linked to a polynucleotide encoding or specifying a gene product, causes the gene product to be produced essentially only in the presence of an inducer corresponding to the promoter.
[0079] A "constitutive" promoter is a nucleotide sequence that, when operably linked to a polynucleotide that encodes or specifies a gene product, causes the gene product to be produced in a cell under most or all physiological conditions in that cell.
[0080] As used herein, the term "polynucleotide" is defined as a chain of nucleotides. Furthermore, a nucleic acid is a polymer of nucleotides. Thus, as used herein, nucleic acid and polynucleotide are interchangeable. It is common knowledge among those skilled in the art that a nucleic acid is a polynucleotide that can be hydrolyzed into monomeric "nucleotides." Monomeric nucleotides can be hydrolyzed into nucleosides. As used herein, polynucleotides include, but are not limited to, all nucleic acid sequences obtained by any means available in the art, including, but not limited to, recombinant methods, i.e., cloning nucleic acid sequences from a recombinant library or a cell genome using conventional cloning techniques and PCR, as well as synthetic methods.
[0081] In the context of the present invention, the following abbreviations for commonly used nucleic acid bases are used: "A" refers to adenosine, "C" refers to cytosine, "G" refers to guanosine, "T" refers to thymidine, and "U" refers to uridine.
[0082] As used herein, the terms "peptide", "polypeptide" and "protein" are used interchangeably and refer to a compound consisting of amino acid residues covalently linked by peptide bonds. A protein or peptide must contain at least two amino acids and there is no limit on the maximum number of amino acids that can constitute a protein or peptide sequence. Polypeptides include any peptide or protein comprising two or more amino acids linked to each other by peptide bonds. As used herein, the term refers to both short chains (which are also commonly referred to in the art as, for example, peptides, oligopeptides and oligomers) and longer chains (which are generally referred to in the art as proteins), of which there are many types. "Polypeptide" includes, for example, biologically active fragments, substantially homologous polypeptides, oligopeptides, homodimers, heterodimers, variants of polypeptides, modified polypeptides, derivatives, analogs, fusion proteins, and the like. Polypeptides include natural peptides, recombinant peptides, synthetic peptides, or combinations thereof.
[0083] The term "RNA" as used herein is defined as ribonucleic acid.
[0084] As used herein, the term "ribozyme" refers to an RNA molecule that can act as an enzyme. For example, some ribozymes can cut RNA molecules. RNA-cleaving ribozymes generally consist of at least a catalytic domain and a recognition sequence recognized by the catalytic domain. The catalytic domain can be a portion of an RNA molecule identical to the recognition sequence, thereby mediating cis-cleavage. Alternatively, the catalytic domain can be an RNA molecule separate from the RNA molecule comprising the recognition sequence, thereby mediating trans-cleavage.
[0085] "Recombinant polynucleotide" refers to a polynucleotide having sequences that are not naturally linked together. The amplified or assembled recombinant polynucleotide can be contained in a suitable vector, and the vector can be used to transform a suitable host cell.
[0086] A recombinant polynucleotide may also have non-coding functions (eg, promoter, origin of replication, ribosome binding site, etc.).
[0087] The term "recombinant polypeptide" as used herein is defined as a polypeptide produced by the use of recombinant DNA methodologies.
[0088] As used herein, the terms "solid surface," "solid support," and other grammatical equivalents thereof refer to any material that is or can be modified to be suitable for the attachment of biomolecules (eg, nucleic acid molecules).
[0089] As used herein, the term "tag" refers to any chemical modification of a biomolecule (eg, a nucleic acid molecule) that provides additional functionality (eg, attachment to a solid support, fluorescent visualization, etc.).
[0090] As used herein, the term "variant" is a nucleic acid sequence or peptide sequence that is different in sequence from a reference nucleic acid sequence or peptide sequence but retains the basic biological properties of the reference molecule. Changes in the nucleic acid variant sequence may not change the amino acid sequence of the peptide encoded by the reference nucleic acid, or may result in amino acid substitutions, additions, deletions, fusions, and truncations. Changes in peptide variant sequences are generally limited or conservative, so the sequences of the reference peptide and variant are very similar overall and are identical in many regions. The amino acid sequences of variants and reference peptides may differ by one or more substitutions, additions, deletions in any combination. The variant of a nucleic acid or peptide may be naturally occurring (such as an allelic variant), or may be a variant for which it is not yet known whether it occurs naturally. Non-naturally occurring variants of nucleic acids and peptides can be prepared by mutagenesis techniques or by direct synthesis.
[0091] A "vector" is a composition of matter that contains an isolated nucleic acid and can be used to deliver the isolated nucleic acid to the interior of a cell. Many vectors are known in the art, including but not limited to linear polynucleotides, polynucleotides associated with ions or amphiphilic compounds, plasmids, and viruses. Therefore, the term "vector" includes autonomously replicating plasmids or viruses. The term should also be interpreted as including non-plasmid and non-viral compounds that facilitate the transfer of nucleic acids into cells, such as, for example, polylysine compounds, liposomes, etc. Examples of viral vectors include but are not limited to adenoviral vectors, adeno-associated viral vectors, retroviral vectors, etc.
[0092] Range: Throughout this disclosure, various aspects of the invention may be presented in a range format. It should be understood that descriptions in range format are for convenience and brevity only and should not be construed as rigid limitations on the scope of the invention. Thus, descriptions of ranges should be considered to have specifically disclosed all possible subranges and individual numbers within that range. For example, descriptions of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as 1 to 3, 1 to 4, 1 to 5, 2 to 4, 2 to 6, 3 to 6, etc., as well as individual numbers within that range, such as 1, 2, 2.7, 3, 4, 5, 5.3, and 6. This applies to any breadth of range.
[0093] Details
[0094] The present invention provides compositions and methods for effectively and reliably linking two or more independent RNA molecules to produce larger single RNA molecules of coded proteins and fusion proteins. The present invention utilizes the trans-splicing of ribozyme-mediated multiple RNA molecules to assemble single RNA molecules encoding target proteins or fusion proteins. The present invention can be used for effectively producing fusion proteins, chimeric proteins, etc. Further, the present invention can be used for producing large full-length proteins, and its coding sequence may be too large to be packaged into a single vector. Further, the technology of the present invention also allows fast and easy combination of two different sequences, which can have a multiplier effect (multiplier effect) for producing new protein combinations or library sequences. This may, for example, be particularly useful for producing synthetic antibodies (such as nano antibodies) or for the functional selection of enzymes.
[0095] The present invention also provides compositions and methods for effectively delivering one or more RNA molecules having synthetic introns flanked by ribozymes. The synthetic intron flanked by ribozymes can be placed between a first RNA portion encoding the N-terminal portion of a target protein and a second RNA portion encoding the C-terminal portion of the target protein. The synthetic intron flanked by ribozymes can contain a cargo sequence, for example, a sequence encoding a therapeutic protein or comprising a functional RNA. The use of two ribozymes allows cis-splicing to produce the following three RNA fragments: 1) a first RNA portion encoding the N-terminal portion of the target protein, 2) a synthetic intron flanked by ribozymes, and 3) a second RNA portion encoding the C-terminal portion of the target protein. The cis-splicing produces compatible ends for ligation. The ligation of the compatible ends of the cis-spliced synthetic introns produces a circular RNA molecule, which is more resistant to degradation than linear RNA molecules. The ligation of the compatible ends of the first RNA portion encoding the N-terminal portion of the target protein and the second RNA portion encoding the C-terminal portion of the target protein produces an RNA molecule encoding the full-length target protein. The full-length protein of interest can be, for example, a therapeutic protein, a CRISPR-Cas protein, or a reporter protein used to provide a proxyindicator for the delivery and expression of a cargo sequence in a circular RNA molecule comprising a synthetic intron flanked by a ribozyme.
[0096] On the one hand, the invention provides one or more nucleic acid molecules encoding two or more RNA molecules.In certain embodiments, one or more in this RNA molecule comprise ribozyme.In one embodiment, one or more in this RNA molecule comprise coding region and ribozyme.In certain embodiments, ribozyme self-cutting breaks away from RNA molecule, thereby leaves coding region.The exemplary ribozyme that can use in the context of the present invention includes but is not limited to the member of hammerhead (HH) ribozyme, hepatitis D virus (HDV) ribozyme, Varkud satellite (VS) ribozyme, Sister ribozyme, Twister-sister ribozyme, hairpin ribozyme, Hatchet ribozyme and Pistol ribozyme family.
[0097] For example, in one embodiment, the composition comprises a nucleic acid molecule encoding a first RNA molecule, wherein the first RNA molecule comprises a coding region and a 3' ribozyme, wherein the 3' ribozyme is capable of catalyzing its own detachment from the RNA molecule, thereby leaving a coding region having a 3'P or 2'3' cyclic phosphate (cP) end. In one embodiment, the 3' ribozyme comprises an HDV ribozyme. Further, in one embodiment, the composition comprises a nucleic acid molecule encoding a second RNA molecule, wherein the second RNA molecule comprises a coding region and a 5' ribozyme, wherein the 5' ribozyme is capable of catalyzing its own detachment from the RNA molecule, thereby leaving a coding region having a 5'OH end. In one embodiment, the 5' ribozyme comprises an HH ribozyme. In some cases, a ligase connects the coding region of the first RNA molecule to the coding region of the second RNA molecule, thereby forming a longer RNA molecule encoding a protein of interest.
[0098] For example, in one embodiment, the composition comprises a first RNA molecule, wherein the first RNA molecule comprises a coding region and a 3' ribozyme, wherein the 3' ribozyme is capable of catalyzing its own detachment from the RNA molecule, thereby leaving a coding region having a 3'P or 2'3' cyclic phosphate (cP) end. In one embodiment, the 3' ribozyme comprises an HDV ribozyme. Further, in one embodiment, the composition comprises a second RNA molecule, wherein the second RNA molecule comprises a coding region and a 5' ribozyme, wherein the 5' ribozyme is capable of catalyzing its own detachment from the RNA molecule, thereby leaving a coding region having a 5'OH end. In one embodiment, the 5' ribozyme comprises an HH ribozyme. In some cases, a ligase connects the coding region of the first RNA molecule to the coding region of the second RNA molecule, thereby forming a longer RNA molecule encoding a protein of interest.
[0099] In certain embodiments, the first RNA comprises a coding region encoding a first portion of a protein of interest, and the second RNA comprises a coding region encoding a second portion of a protein of interest, such that ribozyme-mediated RNA molecule cleavage and ligase-mediated RNA molecule assembly result in the production of RNA molecules encoding proteins having the first and second portions. The present invention can be used to produce full-length proteins from a variety of RNAs, each of which comprises a coding region encoding a portion of a full-length protein. Further, the present invention can be used to produce fusion proteins comprising multiple domains, wherein each of which comprises a coding region encoding a domain of a fusion protein. For example, the present invention can be used to produce RNA molecules encoding proteins having a leader sequence, an N-terminal tag, a C-terminal tag, etc. by assembling RNA from a first RNA comprising a coding sequence encoding a leader sequence, an N-terminal tag, or a C-terminal tag and a second RNA molecule comprising a coding sequence encoding a protein.
[0100] In certain embodiments, the present invention relates to forming a single RNA molecule by three or more separate RNA molecules. For example, in some aspects, the composition comprises a nucleic acid molecule encoding a first RNA molecule, wherein the first RNA molecule comprises a coding region for an N-terminal region encoding a protein; a nucleic acid molecule encoding a second RNA molecule, wherein the second RNA molecule comprises a coding region for a C-terminal region encoding a protein; and one or more nucleic acid molecules encoding one or more additional RNA molecules, each of which comprises a coding region for a domain (e.g., a repeat domain) encoding a protein. In one embodiment, the first RNA molecule comprises a coding region encoding an N-terminal region and a 3' ribozyme, wherein the 3' ribozyme is capable of catalyzing itself from the RNA molecule, thereby leaving a coding region with a 3'P or 2'3' cyclic phosphate (cP) end. In one embodiment, the 3' ribozyme comprises an HDV ribozyme. In one embodiment, the second RNA molecule comprises a coding region encoding a C-terminal region and a 5' ribozyme, wherein the 5' ribozyme is capable of catalyzing itself from the RNA molecule, thereby leaving a coding region with a 5'OH end. In one embodiment, the 5' ribozyme comprises an HH ribozyme. In one embodiment, the additional RNA molecules each comprise a coding region encoding a protein domain, a 3' ribozyme, and a 5' ribozyme. In one embodiment, the 3' ribozyme is an HDV ribozyme. In one embodiment, the 5' ribozyme is an HH ribozyme. In some aspects, the 3' ribozyme is capable of catalyzing its own detachment from the RNA molecule and the 5' ribozyme is capable of catalyzing its own detachment from the RNA molecule, thereby leaving a coding region having a 5'OH and 3'P or 2'3'cP terminus. In one embodiment, the additional RNA molecules each comprise a coding region encoding a protein domain, a 5' ribozyme, and a 3' ribozyme recognition sequence. In some aspects, the 5' ribozyme is capable of catalyzing its own detachment from the RNA molecule, thereby leaving a coding region having a 5'OH terminus; and the 3' ribozyme recognition sequence interacts with the ribozyme to induce the 3' ribozyme recognition sequence to be spliced out of the RNA molecule, thereby leaving a coding region having a 3'P or 2'3'cP terminus. In one embodiment, the 3' ribozyme recognition sequence comprises a Vsv1 sequence that interacts with the VS ribozyme. This technology can be used to generate RNA molecules encoding proteins with multiple repeat domains by sequentially adding coding regions encoding repeat domains by sequentially providing ribozymes (e.g., VS ribozymes) to interact with the 3' ribozyme recognition sequence to generate a 3'P or 2'3'cP terminus, and then ligating the coding regions to the 5'OH terminus of another coding region encoding a repeat domain. In certain aspects, the sequential addition of repeat domains can be performed on a solid substrate or support, wherein the first RNA molecule encoding the N-terminal region is bound to the substrate or support.
[0101] In some aspects, multiple RNA molecules are linked together after ribozyme-mediated generation of 5'OH and 3'P or 2'3'cP termini. In some cases, the RNA molecules are linked together by endogenous ligases present in the natural cells or tissues where RNA assembly occurs. In some cases, the methods of the present invention include the step of adding an exogenous ligase to induce the processed RNA molecules to link together. In one embodiment, the ligase is RNA 2', 3'-cyclic phosphate and 5'-OH (RtcB) ligase.

[0120] Pre-mRNA splicing by the spliceosome has been shown to enhance mRNA translation by depositing factors that promote the first round of translation or by promoting RNA processing and export to the cytoplasm. The addition of chimeric cis-splicing introns within the transgene has also been shown to promote transgenic protein expression. Therefore, in certain embodiments, the addition of splice donor and splice acceptor sites that are recognized and cis-spliced by the spliceosome can enhance protein expression from the split precursor RNA molecule. In one embodiment, the composition comprises one or more RNA molecules that comprise a splice donor or splice acceptor sequence. In one embodiment, the first RNA molecule of the composition comprises a splice donor sequence.

[0124] As described herein, when one RNA contains a 3' ribozyme and the other contains a 5' ribozyme, ribozyme-mediated trans-splicing can occur between the two independent RNAs. However, when transcribed in cis within the same RNA molecule, the two ribozymes can mediate their own scarless removal. This approach similarly produces two independent RNAs with 3'-P and 5'OH ends that can undergo trans-splicing and translation in cells. Including a cargo sequence between the 3' and 5' ribozymes also creates the possibility of generating a circularized RNA molecule upon ligation.

[0140] In some embodiments, one or more nucleic acids of the invention comprise a nucleic acid sequence that is a portion of a nucleic acid sequence described herein and is substantially homologous to a nucleic acid sequence described herein.

For example, in one embodiment, the composition comprises an isolated DNA molecule encoding a fusion protein of the present invention, including, for example, an isolated cDNA molecule. In one embodiment, the composition comprises an isolated RNA molecule encoding a fusion protein of the present invention or a functional fragment thereof.
[0142] Nucleic acid molecules of the present invention can be modified to improve stability in serum or in the growth medium for cell culture. Modification can be added to enhance stability, functionality and / or specificity and minimize the immunostimulatory properties of nucleic acid molecules of the present invention. For example, in order to enhance stability, 3'-residues can be stabilized to prevent degradation, for example, they can be selected so that they are composed of purine nucleotides, particularly adenosine or guanosine nucleotides. Alternatively, pyrimidine nucleotides can be tolerated by the replacement of modified analogs (for example uridine is replaced by 2'-deoxythymidine) and do not affect the function of this molecule.
[0143] In one embodiment of the present invention, the nucleic acid molecule may contain at least one modified nucleotide analog. For example, the termini may be stabilized by incorporating modified nucleotide analogs.
[0144] Non-limiting examples of nucleotide analogs include ribonucleotides with modified sugars and / or backbones (i.e., including modifications to the phosphate-sugar backbone). For example, the phosphodiester linkages of natural RNA can be modified to incorporate at least one of a nitrogen or sulfur heteroatom. In exemplary backbone-modified ribonucleotides, the phosphate groups connected to adjacent ribonucleotides are replaced by modified groups (e.g., phosphorothioate groups). In exemplary sugar-modified ribonucleotides, the 2'OH- group is replaced by a group selected from H, OR, R, halo, SH, SR, NH2, NHR, NR2, or ON, wherein R is a C1-C6 alkyl, alkenyl, or alkynyl group, and the halo is F, Cl, Br, or I.
[0145] Other examples of modifications are ribonucleotides with modified nucleobases, i.e., ribonucleotides containing at least one non-natural nucleobase instead of a naturally occurring nucleobase. The base can be modified to block the activity of adenosine deaminase. Exemplary modified nucleobases include, but are not limited to, uridine and / or cytidine modified at the 5-position, such as 5-(2-amino)propyluridine, 5-bromouridine; adenosine and / or guanosine modified at the 8-position, such as 8-bromoguanosine; deazanucleotides, such as 7-deaza-adenosine; O-alkylated nucleotides and N-alkylated nucleotides, such as N6-methyladenosine are suitable. It should be noted that the above modifications can be combined.
[0146] In some cases, the nucleic acid molecule comprises at least one of the following chemical modifications: 2'-H, 2'-O-methyl or 2'-OH modifications of one or more nucleotides. In certain embodiments, the nucleic acid molecules of the present invention can have enhanced resistance to nucleases. In order to increase nuclease resistance, the nucleic acid molecule can comprise, for example, 2'-modified ribose units and / or thiophosphate linkages. For example, the 2'hydroxyl (OH) can be modified or replaced by many different "oxy" or "deoxy" substituents. In order to increase nuclease resistance, the nucleic acid molecules of the present invention can comprise 2'-O-methyl, 2'-fluoro, 2'-O-methoxyethyl, 2'-O-aminopropyl, 2'-amino and / or thiophosphate linkages. The inclusion of locked nucleic acids (LNA), ethylene nucleic acids (ENA) (e.g., 2'-4'-ethylene bridged nucleic acids), and certain core base modifications (such as 2-amino-A, 2-thio (e.g., 2-thio-U), G-clamp modifications) can also increase binding affinity to the target.
[0147] In one embodiment, the nucleic acid molecule includes 2'-modified nucleotides, such as 2'-deoxy, 2'-deoxy-2'-fluoro, 2'-O-methyl, 2'-O-methoxyethyl (2'-O-MOE), 2'-O-aminopropyl (2'-O-AP), 2'-O-dimethylaminoethyl (2'-O-DMAOE), 2'-O-dimethylaminopropyl (2'-O-DMAP), 2'-O-dimethylaminoethoxyethyl (2'-O-DMAEOE), or 2'-O-N-methylacetamido (2'-O-NMA). In one embodiment, the nucleic acid molecule includes at least one 2'-O-methyl modified nucleotide, and in some embodiments, all nucleotides of the nucleic acid molecule include a 2'-O-methyl modification.
[0148] In certain embodiments, nucleic acid molecules of the invention have one or more of the following properties:
[0149] Nucleic acid agents discussed herein include otherwise unmodified RNA and DNA and RNA and DNA that have been modified, for example, to improve efficacy, and polymers of nucleoside substitutes. Unmodified RNA refers to molecules in which the components of nucleic acid (i.e., sugar, base, and phosphate moieties) are identical or substantially identical to naturally occurring components in nature or in the human body. Rare or uncommon but naturally occurring RNA is referred to in the art as modified RNA, see, for example, Limbach et al. (Nucleic Acids Res., 1994, 22: 2183-2196). Such rare or uncommon RNAs often referred to as modified RNAs are typically the result of post-transcriptional modifications and are within the scope of unmodified RNA as used herein. Modified RNA as used herein refers to molecules in which one or more components of nucleic acid components (i.e., sugar, base, and phosphate moieties) are different from one or more components present in nature or from one or more components present in the human body. Although they are referred to as "modified RNAs," they certainly include molecules that are not strictly speaking RNAs because of modification. Nucleoside surrogates are molecules in which the ribose phosphate backbone is replaced with a non-ribose phosphate construct that allows the bases to be presented in the correct spatial relationship, such that hybridization is substantially similar to that seen with the ribose phosphate backbone (e.g., an uncharged mimetic of the ribose phosphate backbone).
[0150] Modifications of the nucleic acids of the invention may occur at one or more of the phosphate group, sugar group, backbone, N-terminus, C-terminus, or nucleobases.

[0155] There are many suitable vectors that can be used for the present invention in this area.In short, the expression of the natural or synthetic nucleic acid encoding the fusion protein of the present invention is usually achieved by operably linking the nucleic acid encoding the fusion protein of the present invention or its part to a promoter, and incorporating the construct into the expression vector. The carrier to be used is suitable for replication and optionally integration in eukaryotic cells. Typical carriers contain transcription and translation terminators, initiation sequences, and promoters that can be used to regulate the expression of the desired nucleic acid sequence.
[0156] The vectors of the present invention can also be used for nucleic acid immunization and gene therapy using standard gene delivery protocols. Methods for gene delivery are known in the art. See, for example, U.S. Patent Nos. 5,399,346, 5,580,859, and 5,589,466, which are incorporated herein by reference in their entirety.

[0159] Furthermore, many other viral-based systems have been developed for transferring genes into mammalian cells. For example, retroviruses provide a convenient platform for gene delivery systems. The selected gene can be inserted into a vector and packaged into retroviral particles using techniques known in the art. The recombinant virus can then be isolated and delivered to the subject's cells in vivo or ex vivo. Many retroviral systems are known in the art. In some embodiments, adenoviral vectors are used. Many adenoviral vectors are known in the art.
[0160] In one embodiment, the composition comprises a vector derived from an adeno-associated virus (AAV). The term "AAV vector" means a vector derived from an adeno-associated virus serotype, including but not limited to AAV-1, AAV-2, AAV-3, AAV-4, AAV-5, AAV-6, AAV-7, AAV-8 and AAV-9. AAV vectors have become powerful gene delivery tools for treating various diseases. AAV vectors have many features that make them very suitable for gene therapy, including lack of pathogenicity, minimal immunogenicity and the ability to transduce post-mitotic cells in a stable and effective manner. By selecting an appropriate combination of AAV serotype, promoter and delivery method, the expression of the specific gene contained in the AAV vector can be specifically targeted to one or more types of cells.
[0161] AAV vectors can have a complete or partial deletion of one or more AAV wild-type genes (preferably the rep and / or cap genes), but retain functional flanking ITR sequences. Despite the high degree of homology, different serotypes have tropisms for different tissues. The receptor for AAV1 is unknown; however, it is known that AAV1 transduces skeletal and cardiac muscle more efficiently than AAV2. Since most studies have been done with pseudotyped vectors, in which vector DNA flanked by AAV2 ITRs is packaged into capsids of the alternate serotype, it is clear that the biological differences are capsid-related rather than genome-related. Recent evidence suggests that DNA expression cassettes packaged in AAV 1 capsids are at least 1 log10 more efficient at transducing cardiomyocytes than those packaged in AAV2 capsids. In one embodiment, the viral delivery system is an adeno-associated viral delivery system. The adeno-associated virus can be serotype 1 (AAV 1), serotype 2 (AAV2), serotype 3 (AAV3), serotype 4 (AAV4), serotype 5 (AAV5), serotype 6 (AAV6), serotype 7 (AAV7), serotype 8 (AAV8) or serotype 9 (AAV9).
[0162] Ideal AAV fragments for assembly into vectors include cap proteins (including vp1, vp2, vp3 and hypervariable regions), rep proteins (including rep 78, rep 68, rep 52 and rep 40), and sequences encoding these proteins. These fragments can be easily used in various vector systems and host cells. Such fragments can be used alone, in combination with other AAV serotype sequences or fragments, or in combination with elements from other AAV or non-AAV viral sequences. As used herein, artificial AAV serotypes include, but are not limited to, AAVs with non-naturally occurring capsid proteins. Such artificial capsids can be produced by any suitable technique using a combination of selected AAV sequences (e.g., fragments of vp1 capsid proteins) and heterologous sequences, which can be obtained from different selected AAV serotypes, non-contiguous parts of the same AAV serotype, non-AAV viral sources, or non-viral sources. Artificial AAV serotypes can be, but are not limited to, chimeric AAV capsids, recombinant AAV capsids, or "humanized" AAV capsids. Thus, exemplary AAVs or artificial AAVs suitable for expressing one or more proteins include AAV2 / 8 (see U.S. Pat. No. 7,282,199), AAV2 / 5 (available from the National Institutes of Health), AAV2 / 9 (International Patent Publication No. WO2005 / 033321), AAV2 / 6 (U.S. Pat. No. 6,156,303), and AAVrh8 (International Patent Publication No. WO2003 / 042397), among others.
[0163] In one embodiment, the composition comprises a lentiviral vector to deliver one or more nucleic acids of the present invention. In one embodiment, the present invention includes a lentiviral vector comprising one or more RNA molecules encoding one or more target proteins. For example, vectors derived from retroviruses (such as lentiviruses) are suitable tools for achieving long-term gene transfer because they allow long-term stable integration of transgenes and propagation of transgenes in daughter cells. Lentiviral vectors have additional advantages over vectors derived from oncometaviruses (such as murine leukemia viruses) because they can transduce non-proliferating cells, such as hepatocytes. They also have the additional advantage of low immunogenicity.
[0164] In certain embodiments, the vector further comprises conventional control elements that are operably linked to the transgene in a manner that allows it to be transcribed, translated, and / or expressed in cells transfected with the plasmid vector or infected with the virus produced by the present invention. As used herein, "operably linked" sequences include expression control sequences that are adjacent to the gene of interest and expression control sequences that act in trans or remotely to control the gene of interest. Expression control sequences include appropriate transcription initiation, termination, promoter, and enhancer sequences; efficient RNA processing signals, such as splicing and polyadenylation (polyA) signals; sequences that stabilize cytoplasmic mRNA; sequences that improve translation efficiency (i.e., Kozak consensus sequences); sequences that enhance protein stability; and, where desired, sequences that enhance secretion of the encoded product. A large number of expression control sequences, including natural, constitutive, inducible, and / or tissue-specific promoters, are known in the art and can be used.
[0165] Additional promoter elements (such as enhancers) regulate the frequency of transcription initiation. Usually, these are located in the region of 30-110bp upstream of the start site, but recently it has been shown that many promoters also contain functional elements located downstream of the start site. The spacing between the promoter elements is normally flexible, so when elements are inverted or moved relative to each other, promoter function is retained. In the thymidine kinase (tk) promoter, before activity began to decline, the spacing between the promoter elements could be increased to 50bp. Depending on the promoter, it seems that each element can work together or independently to activate transcription.
[0166] An example of a suitable promoter is the immediate early cytomegalovirus (CMV) promoter sequence. This promoter sequence is a strong constitutive promoter sequence that can drive the high-level expression of any polynucleotide sequence operably linked thereto. Another example of a suitable promoter is elongation growth factor-1α (EF-1α). However, other constitutive promoter sequences can also be used, including but not limited to simian virus 40 (SV40) early promoter, mouse mammary tumor virus (MMTV), human immunodeficiency virus (HIV) long terminal repeat (LTR) promoter, MoMuLV promoter, avian leukosis virus promoter, Epstein-Barr virus (Epstein-Barr virus) immediate early promoter, Rous sarcoma (Roussarcoma) virus promoter, and human gene promoters, such as but not limited to actin promoter, myosin promoter, hemoglobin promoter and creatine kinase promoter. Further, the present invention should not be limited to the use of constitutive promoters. Inducible promoters are also considered to be part of the present invention. The use of an inducible promoter provides a molecular switch that can turn on expression of the polynucleotide sequence to which it is operably linked when such expression is desired, or turn off expression when such expression is not desired. Examples of inducible promoters include, but are not limited to, metallothionine promoters, glucocorticoid promoters, progesterone promoters, and tetracycline promoters.
[0167] Enhancer sequences found on vectors also regulate the expression of genes contained therein. Typically, enhancers are combined with protein factors to enhance the transcription of the gene. The enhancer may be located upstream or downstream of the gene it regulates. The enhancer may also be tissue-specific, to enhance the transcription in a particular cell or tissue type. In one embodiment, vectors of the present invention comprise one or more enhancers to promote the transcription of the gene present in the vector.
[0168] In order to assess the expression of fusion protein of the present invention, the expression vector to be introduced into the cell can also contain selectable marker gene or reporter gene or both, to promote identifying and selecting expressing cells from the cell mass seeking to be transfected by viral vector or infected. In other aspects, selectable marker can be carried on an independent DNA fragment and be used in the cotransfection program. Both selectable marker and reporter gene can be flanked by suitable regulatory sequences to enable it to be expressed in host cells. Useful selectable markers include, for example, antibiotic resistance genes, such as neo etc.
[0169] Reporter gene is used to identify the functionality of the cell that may be transfected and assessment control sequence. Generally speaking, reporter gene is such gene, and this gene is not present in receptor organism or tissue or is not expressed by receptor organism or tissue, and encodes such polypeptide, and the expression of this polypeptide can be proved by some easily detectable characteristics (such as enzymatic activity). The expression of reporter gene is measured at the appropriate time after DNA is introduced into the receptor cell. Suitable reporter gene can include the gene (for example, Ui-Tei et al., 2000FEBS Letters 479:79-82) of coding luciferase, beta-galactosidase, chloramphenicol acetyltransferase, secretory alkaline phosphatase or green fluorescent protein gene. Suitable expression system is well-known and can use known technology to prepare or commercially obtain. Generally speaking, the construct with the minimum 5 ' flanking region that demonstrates the highest level of reporter gene expression is accredited as promoter. This type of promoter region can be connected with reporter gene and can be used to the ability of transcription driven by assessment agent regulation promoter.

[0176] The present invention also encompasses the use of pharmaceutical compositions of the present invention or salts thereof for implementing the methods of the present invention. Such pharmaceutical compositions may be composed of at least one nucleic acid of the present invention or a salt thereof in a form suitable for administration to a subject, or the pharmaceutical composition may comprise at least one nucleic acid of the present invention or a salt thereof, and one or more pharmaceutically acceptable carriers, one or more additional ingredients, or some combination thereof. The nucleic acids of the present invention may be present in the form of physiologically acceptable salts, for example in pharmaceutical compositions in combination with physiologically acceptable cations or anions as known in the art.

In another embodiment, the pharmaceutical composition useful for practicing the methods of the present invention can be administered to deliver a dose between 1 ng / kg / day and 500 mg / kg / day.
[0178] The relative amounts of the active ingredient, pharmaceutically acceptable carrier, and any other ingredients in the pharmaceutical compositions of the present invention will vary depending on the identity, size, and condition of the subject being treated and further on the route of administration of the composition. For example, the composition may contain between 0.1% and 100% (w / w) active ingredient.
[0179] Pharmaceutical compositions useful in the methods of the present invention may be suitably developed for oral, rectal, vaginal, parenteral, topical, pulmonary, intranasal, buccal, ocular administration or another route of administration. Compositions useful in the methods of the present invention may be applied directly to the skin or any other tissue of a mammal. Other contemplated formulations include liposomal formulations, resealed erythrocytes containing the active ingredient, and immunologically based formulations. The route or routes of administration will be readily apparent to those skilled in the art and will depend on a number of factors, including the type and severity of the disease being treated, the type and age of the veterinary or human subject being treated, and the like.
[0180] The formulations of the pharmaceutical compositions described herein can be prepared by any method known in the art of pharmacology or later developed in the art of pharmacology. Generally speaking, such preparation methods include the steps of combining the active ingredient with a carrier or one or more other auxiliary ingredients, and then, if necessary or desired, shaping or packaging the product into the desired single or multi-dose units.
[0181] As used herein, a "unit dose" is a discrete amount of a pharmaceutical composition containing a predetermined amount of an active ingredient. The amount of the active ingredient is generally equal to the dose of the active ingredient to be administered to a subject or a convenient fraction of such a dose, such as, for example, one-half or one-third of such a dose. The unit dosage form can be a single daily dose, or a single dose of multiple daily doses (e.g., about 1 to 4 times or more per day). When multiple daily doses are used, the unit dosage form of each dose can be the same or different.
[0182] In one embodiment, the compositions of the present invention are formulated using one or more pharmaceutically acceptable excipients or carriers. In one embodiment, the pharmaceutical compositions of the present invention comprise a therapeutically effective amount of the nucleic acid of the present invention and a pharmaceutically acceptable carrier. Useful pharmaceutically acceptable carriers include, but are not limited to, glycerol, water, physiological saline, ethanol, and other pharmaceutically acceptable saline solutions, such as phosphates and organic acid salts. Examples of these and other pharmaceutically acceptable carriers are described in Remington's Pharmaceutical Sciences (1991, Mack Publication Co., New Jersey).
[0183] The carrier can be a solvent or dispersion medium, and it contains for example water, ethanol, polyol (for example glycerol, propylene glycol and liquid polyethylene glycol etc.), their suitable mixture, and vegetable oil.For example, by using a coating such as lecithin, by keeping required particle size in the case of dispersion, and by using a surfactant, suitable fluidity can be maintained. The prevention of microbial action can be achieved by various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol, ascorbic acid, thimerosal etc. In many cases, isotonic agents are included in the compositions, such as sugar, sodium chloride or polyol, such as mannitol and sorbitol. The absorption of the compositions can be extended by including the agent that delays absorption in the injectable composition, such as aluminum monostearate or gelatin. In one embodiment, the pharmaceutically acceptable carrier is not independent DMSO.
[0184] The preparations can be mixed with conventional excipients (i.e., pharmaceutically acceptable organic or inorganic carrier materials suitable for oral, vaginal, parenteral, nasal, intravenous, subcutaneous, enteral, or any other suitable mode of administration known in the art). The pharmaceutical formulations can be sterilized and, if necessary, mixed with adjuvants (e.g., lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, colorants, flavorings, and / or aromatic substances). They can also be combined with other active agents, such as other analgesics, when necessary.
[0185] As used herein, "additional ingredients" include, but are not limited to, one or more of the following: excipients; surfactants; dispersants; inert diluents; granulating and disintegrants; binders; lubricants; sweeteners; flavorings; colorants; preservatives; physiologically degradable compositions, such as gelatin; aqueous vehicles and solvents; oily vehicles and solvents; suspending agents; dispersants or wetting agents; emulsifiers, demulcents; buffers; salts; thickeners; fillers; emulsifiers; antioxidants; antibiotics; antifungal agents; stabilizers; and pharmaceutically acceptable polymeric or hydrophobic materials. Other "additional ingredients" that may be included in the pharmaceutical compositions of the present invention are known in the art and are described, for example, in Genaro, ed. (1985, Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, PA), which is incorporated herein by reference.
[0186] The compositions of the present invention may contain from about 0.005% to 2.0% of a preservative, based on the total weight of the composition. Preservatives are used to prevent deterioration due to exposure to environmental contaminants. Examples of preservatives useful according to the present invention include, but are not limited to, those selected from the group consisting of benzyl alcohol, sorbic acid, parabens, imidoureas, and combinations thereof. An exemplary preservative is a combination of from about 0.5% to 2.0% benzyl alcohol and from 0.05% to 0.5% sorbic acid.
[0187] In one embodiment, the composition comprises an antioxidant and a chelating agent that inhibits nucleic acid degradation. Exemplary antioxidants for some compounds are BHT, BHA, α-tocopherol, and ascorbic acid in the range of about 0.01% to 0.3% by weight of the total weight of the composition, and BHT in the range of 0.03% to 0.1% by weight. In one embodiment, the chelating agent is present in an amount of 0.01% to 0.5% by weight of the total weight of the composition. Exemplary chelating agents include edetates (e.g., disodium edetate) and citric acid in the range of about 0.01% to 0.20% by weight. In some embodiments, the chelating agent is in the range of 0.02% to 0.10% by weight of the total weight of the composition. Chelating agents can be used to chelate metal ions that may be harmful to the shelf life of the preparation in the chelating composition. Although BHT and disodium edetate are exemplary antioxidants and chelating agents for some compounds, other suitable equivalent antioxidants and chelating agents can therefore be substituted, as known to those skilled in the art.
[0188] Conventional methods can be used to prepare liquid suspensions to realize the suspension of active ingredients in aqueous or oily vehicles. Aqueous vehicles include, for example, water and isotonic saline. Oily vehicles include, for example, almond oil, oily esters, ethanol, vegetable oils (such as peanut oil, olive oil, sesame oil or coconut oil), fractionated vegetable oils and mineral oils (such as liquid paraffin). Liquid suspensions can further include one or more additional ingredients, which include but are not limited to suspending agents, dispersants or wetting agents, emulsifiers, moderators, preservatives, buffers, salts, flavorings, coloring agents and sweeteners. Oily suspensions can further include thickening agents. Known suspending agents include but are not limited to sorbitol syrup, hydrogenated edible fats, sodium alginate, polyvinyl pyrrolidone, tragacanth gum, gum arabic and cellulose derivatives (such as sodium carboxymethylcellulose, methylcellulose, hydroxypropyl methylcellulose). Known dispersants or wetting agents include, but are not limited to, naturally occurring phospholipids (such as lecithin); condensation products of alkylene oxides with fatty acids, with long-chain aliphatic alcohols, with partial esters derived from fatty acids and hexitol, or with partial esters derived from fatty acids and hexitol anhydrides (e.g., polyoxyethylene stearate, heptadecaethyleneoxycetanol, polyoxyethylene sorbitol monooleate, and polyoxyethylene sorbitan monooleate, respectively). Known emulsifiers include, but are not limited to, lecithin and gum arabic. Known preservatives include, but are not limited to, methylparaben, ethylparaben, or n-propylparaben, ascorbic acid, and sorbic acid. Known sweeteners include, for example, glycerol, propylene glycol, sorbitol, sucrose, and saccharin. Known thickeners for oily suspensions include, for example, beeswax, hard paraffin, and cetyl alcohol.
[0189] The liquid solution of active component in aqueous or oily solvent can be prepared in the mode substantially the same as liquid suspension, and major difference is that active component is dissolved in solvent, rather than being suspended in solvent.As used herein, " oily " liquid is a kind of liquid that comprises carbon-containing liquid molecule and shows polarity characteristic less than water.The liquid solution of pharmaceutical composition of the present invention can comprise each component in the component described for liquid suspension, and it should be understood that suspending agent will not necessarily contribute to the dissolving of active component in solvent.Aqueous solvent comprises for example water and isotonic saline.Oily solvent comprises for example almond oil, oily ester, ethanol, vegetable oil (such as peanut oil, olive oil, sesame oil or coconut oil), fractionated vegetable oil and mineral oil (such as liquid paraffin).
[0190] The powder and granular formulations of the pharmaceutical formulations of the present invention can be prepared using known methods. Such formulations can be directly administered to a subject and used, for example, to form tablets, fill capsules, or to prepare aqueous or oily suspensions or solutions by adding aqueous or oily vehicles thereto. Each of these formulations can further comprise one or more of a dispersant or wetting agent, a suspending agent, and a preservative. Additional excipients, such as fillers and sweeteners, flavorings, or coloring agents, can also be included in these formulations.
[0191] Pharmaceutical composition of the present invention can also be prepared, packaged or sold in the form of oil-in-water emulsion or water-in-oil emulsion.The oil phase can be vegetable oil (such as olive oil or peanut oil), mineral oil (such as liquid paraffin), or these combinations.This type of composition can further comprise one or more emulsifying agents, such as naturally occurring gum (such as gum arabic or gum tragacanth), naturally occurring phosphatide (such as soybean or lecithin phosphatide), ester or partial ester (such as sorbitan monooleate) derived from the combination of fatty acid and hexitol anhydride, and the condensation product (such as monooleic acid polyoxyethylene sorbitan ester) of this type of partial ester and ethylene oxide.These emulsions can also comprise additional ingredients, comprise for example sweetener or flavoring.
[0192] Methods of impregnating or coating materials with chemical compositions are known in the art and include, but are not limited to, methods of depositing or binding the chemical composition onto a surface, methods of incorporating the chemical composition into the structure of the material during its synthesis (i.e., such as with physiologically degradable materials), and methods of absorbing aqueous or oily solutions or suspensions into an absorbent material (with or without subsequent drying).
[0193] The administration regimen can affect what constitutes an effective amount. The therapeutic formulation can be administered to the subject before or after diagnosis of the disease. Further, several divided doses and staggered doses can be administered daily or sequentially, or the dose can be a continuous infusion or a bolus injection. Further, the dose of the therapeutic formulation can be proportionally increased or decreased according to the urgency of the therapeutic or preventive situation.
[0194] Known procedures can be used to administer the present compositions to subjects (including mammals, such as humans) at dosages and time periods that effectively prevent or treat diseases. The effective amount of the nucleic acid required to achieve the therapeutic effect can vary according to factors such as the following: the activity of the specific nucleic acid used; the time of administration; the excretion rate of the nucleic acid; the duration of treatment; other drugs, compounds, or materials used in combination with the nucleic acid; the state, age, sex, weight, condition, general health, and past medical history of the disease or illness of the subject being treated; and similar factors well-known in the medical field. The dosage regimen can be adjusted to provide the best therapeutic response. For example, several separate doses can be administered daily or the dosage can be proportionally reduced according to the urgency of the treatment situation. A non-limiting example of the effective dose range of the nucleic acid compound of the present invention is about 1 to 5,000 mg / kg body weight / day. One of ordinary skill in the art will be able to study the relevant factors and determine the effective amount of therapeutic nucleic acid without the need for excessive experiments.
[0195] In some embodiments, the nucleic acid of the present invention can be administered to the subject in a manner that is consistent with the present invention.This nucleic acid can be applied to the subject by the frequency of several times every day, or can be applied by lower frequency, for example, once a day, once a week, once every two weeks, once a month, or by even lower frequency application, for example, once every several months or even once a year or longer.Should be understood that, in non-limiting examples, the amount of nucleic acid administered every day can be applied every day, every other day, every 2 days, every 3 days, every 4 days or every 5 days.For example, with regard to application every other day, 5mg / day dosage can be started on Monday, then the first follow-up 5mg / day dosage is applied on Wednesday, then the second follow-up 5mg / day dosage is applied on Friday, and the rest can be deduced by analogy.Dosage frequency will be apparent to technical personnel, and depends on many factors, such as but not limited to the type of the disease treated and the order of severity, the type and the age of the animal etc.
[0196] Actual dosage levels of the active ingredients in the pharmaceutical compositions of the present invention may be varied so as to obtain an amount of the active ingredient that is effective to achieve the desired therapeutic response for a particular subject, composition, and mode of administration, without being toxic to the subject.
[0197] A physician with ordinary skill in the art, such as a physician or veterinarian, can readily determine and prescribe the effective amount of the desired pharmaceutical composition.

See, for example, U.S. Patent Nos. 5,350,674 and 5,585,362.
[0257] Chemical means for introducing polynucleotides into host cells include colloidal dispersion systems, such as macromolecular complexes, nanocapsules, microspheres, beads, and lipid-based systems, including oil-in-water emulsions, micelles, mixed micelles, and liposomes. An exemplary colloidal system for use as a delivery vehicle in vitro and in vivo is a liposome (e.g., an artificial membrane vesicle).
[0258] In the case of using non-viral delivery system, exemplary delivery vehicle is liposome. Consider using lipid preparation to introduce described nucleic acid into host cell (in vitro, in vitro or in vivo). In another aspect, described nucleic acid can be associated with lipid. The nucleic acid associated with lipid can be encapsulated in the aqueous interior of liposome, dispersed in the lipid bilayer of liposome, attached to liposome by the connecting molecule associated with liposome and oligonucleotide, embedded in liposome, compounded with liposome, dispersed in the solution containing lipid, mixed with lipid, combined with lipid, included in lipid as suspension, included or compounded together with micelle, or otherwise associated with lipid. The composition associated with lipid, lipid / DNA or lipid / expression vector is not limited to any specific structure in solution. For example, they may be present in double-layer structure in micellar form, or exist with " collapse " structure. They can also be simply dispersed in solution, thereby may form aggregates of uneven size or shape. Lipid is a fatty substance, and it can be naturally occurring lipid or synthetic lipid. For example, lipids include the fat droplets naturally present in the cytoplasm, as well as a class of compounds containing long-chain aliphatic hydrocarbons and their derivatives, such as fatty acids, alcohols, amines, amino alcohols, and aldehydes.
[0259] Suitable lipids can be obtained from commercial sources. For example, dimyristylphosphatidylcholine ("DMPC") can be obtained from Sigma, St. Louis, MO; dioctyl phosphate ("DCP") can be obtained from K&K Laboratories (Plainview, NY); cholesterol ("Choi") can be obtained from Calbiochem-Behring; dimyristylphosphatidylglycerol ("DMPG") and other lipids can be obtained from Avanti Polar Lipids, Inc. (Birmingham, AL). Stock solutions of lipids in chloroform or chloroform / methanol can be stored at approximately -20°C. Chloroform is used as the only solvent because it evaporates more easily than methanol. "Liposome" is a general term that covers a variety of unilamellar and multilamellar lipid vehicles formed by creating closed lipid bilayers or aggregates. Liposomes can be characterized as having a vesicular structure containing a phospholipid bilayer membrane and an internal aqueous medium. Multilamellar liposomes have multiple lipid layers separated by an aqueous medium. They form spontaneously when phospholipids are suspended in an excess of aqueous solution. The lipid components undergo self-rearrangement before forming a closed structure and entrain water and dissolved solutes between the lipid bilayers (Ghosh et al., 1991 Glycobiology 5:505-10). However, compositions having structures different from normal vesicle structures in solution are also encompassed. For example, lipids may present micellar structures or exist only as heterogeneous aggregates of lipid molecules. Lipofectamine-nucleic acid complexes are also contemplated.
[0260] Regardless of the method used to introduce exogenous nucleic acid into the host cell, a variety of assays can be performed to confirm the presence of the recombinant DNA sequence in the host cell. Such assays include, for example, "molecular biology" assays well known to those skilled in the art, such as Southern and Northern blotting, RT-PCR and PCR; "biochemical" assays, such as detecting the presence or absence of specific peptides, for example, by immunological means (ELISA and Western blotting) or by assays described herein to identify agents falling within the scope of the present invention.
[0261] In one embodiment, the present invention relates to a method for expressing two or more proteins of interest from two or more pairs of independent RNA molecules encoding a portion of the protein of interest by cis-cleavage of a ribozyme and trans-splicing of the paired independent RNA molecules. In one embodiment, the method includes administering one, two, or three pairs of nucleic acid molecules encoding or comprising RNA molecules, wherein each single pair of independent RNA molecules has a separate reading frame so that the trans-splicing of unwanted pairs does not result in translation of full-length functional proteins. In one embodiment, the method further includes administering to cells or tissues one or more of the following groups: nucleic acid molecules encoding a ligase and a ligase. In one embodiment, the ligase is an RNA 2', 3'-cyclic phosphate and a 5'-OH (RtcB) ligase as described herein.
[0262] In one embodiment, the present invention includes a method for delivering and expressing a full-length protein of interest and a cargo sequence. In one embodiment, the method comprises administering to a cell or tissue a first portion of an RNA encoding a first portion of the protein of interest, the first portion of the RNA being linked at its 3' end to a synthetic intron; and a second portion of an RNA encoding a second portion of the protein of interest, the second portion of the RNA being linked at its 5' end to the synthetic intron. In one embodiment, the synthetic intron is flanked on either side by a 5' ribozyme sequence and a 3' ribozyme sequence. In one embodiment, the synthetic intron comprises a cargo sequence positioned between the 5' and 3' ribozyme sequences. In one embodiment, self-cleavage of the 5' and 3' ribozyme sequences produces three separate RNA molecules: 1) a first segment comprising the first portion of the RNA encoding the first portion of the protein of interest; 2) a second segment comprising the synthetic intron; and 3) a third segment comprising the second portion of the RNA encoding the second portion of the protein of interest. In one embodiment, the compatible ends of the second segment are joined to produce a circular RNA molecule comprising the synthetic intron containing the cargo sequence. In one embodiment, the first and third segments are joined together to produce a single, full-length linear RNA molecule. In one embodiment, the full-length protein of interest includes a therapeutic protein, a reporter protein, a recombinase, an antibiotic resistance gene product, an antibody, or a Cas9 protein. In one embodiment, the cargo sequence includes a therapeutic nucleic acid sequence (e.g., a miRNA sequence or a CRISPR guide RNA sequence) or encodes a therapeutic protein. In some embodiments, the full-length protein of interest includes Cas9 and the cargo sequence includes a guide RNA sequence, thereby targeting Cas9 to a specific genomic sequence for editing. In some embodiments, the method includes administering a ligase as described herein or a nucleic acid encoding a ligase to a cell or tissue.
[0263] In one embodiment, the present invention includes a gene editing method comprising one or more trans-cutting engineered ribozymes. In some embodiments, the method comprises administering a first trans-cutting engineered ribozyme and a second trans-cutting engineered ribozyme, wherein the first trans-cutting engineered ribozyme targets the upstream of the pathogenic mutation and the second trans-cutting engineered ribozyme targets the downstream of the pathogenic mutation. In some embodiments, trans-cutting upstream and downstream of the pathogenic mutation leads to the removal of the pathogenic mutation. In some embodiments, after trans-cutting of the pathogenic mutation, the remainder of the gene is trans-spliced together. In some embodiments, the trans-spliced gene is expressed as a functional protein.
[0264] In one embodiment, the present invention relates to an in vivo method for assembling a full-length RNA viral genome. Exemplary RNA viruses include, but are not limited to, coronaviruses, paramyxoviruses, orthomyxoviruses, retroviruses, lentiviruses, alphaviruses, flaviviruses, rhabdoviruses, measles viruses, Newcastle disease viruses, and picornaviruses. In one embodiment, the method comprises administering to a cell or tissue a first nucleic acid encoding a first portion of an RNA viral genome and encoding a 3' ribozyme. In one embodiment, the method comprises administering to a cell or tissue a second nucleic acid encoding a second portion of an RNA viral genome and encoding a 5' ribozyme. In one embodiment, the method comprises administering to a cell or tissue a first RNA molecule comprising the first portion of an RNA viral genome and a 3' ribozyme. In one embodiment, the method comprises administering to a cell or tissue a second RNA molecule comprising the second portion of an RNA viral genome and a 5' ribozyme. In one embodiment, the method comprises administering to a cell or tissue a nucleic acid encoding a ligase as described herein or a ligase.

[0265] in vitro
[0266] In one embodiment, the present invention includes an in vitro method for producing an RNA molecule encoding a protein of interest. In one embodiment, the method includes the step of providing at least two RNA molecules. In one embodiment, the step includes providing a first RNA molecule and a second RNA molecule.
[0267] In one embodiment, the first RNA molecule comprises a coding region encoding a first portion of a target protein. In one embodiment, the first RNA molecule comprises a 3' ribozyme. In one embodiment, the first RNA molecule comprises a coding region encoding a first portion of a target protein and a 3' ribozyme.

In one embodiment, the second RNA molecule comprises a coding region encoding a second portion of the target protein and a 5' ribozyme.
[0269] In one embodiment, the in vitro method for producing an RNA molecule encoding a protein of interest further comprises providing a ligase. In one embodiment, the ligase induces assembly of an RNA molecule from the coding region of a first RNA molecule and the coding region of a second RNA molecule. In one embodiment, the ligase is an RNA 2', 3'-cyclic phosphate and 5'-OH (RtcB) ligase as described herein.
[0270] In one embodiment, the invention includes an in vitro method for producing an RNA molecule encoding a multi-domain protein of interest. In one embodiment, the method comprises the steps of: a) providing a first RNA molecule, b) providing one or more additional RNA molecules, c) providing a ribozyme, and d) providing a final RNA molecule.
[0271] In one embodiment, the first RNA molecule of step a) comprises a coding region encoding a first portion of a protein of interest. In one embodiment, the first RNA molecule comprises a 3' ribozyme. In one embodiment, the first RNA molecule comprises a coding region encoding a first portion of a protein of interest and a 3' ribozyme. In one embodiment, the 3' ribozyme catalyzes its own detachment from the first RNA molecule, thereby producing a 3'P or 2'3'cP end. In one embodiment, the first RNA molecule further comprises a 5' tag. In one embodiment, the 5' tag mediates attachment of the first RNA molecule to a solid support.
[0272] In one embodiment, the one or more additional RNA molecules of step b) comprise a coding region encoding a domain of a protein of interest, a 5' ribozyme, and a 3' ribozyme recognition sequence. In one embodiment, the 5' ribozyme cleaves itself to produce a 5' OH terminus. In one embodiment, a ligase is provided to catalyze the attachment of the first RNA molecule to the one or more additional RNA molecules. In one embodiment, the ligase is an RNA 2', 3'-cyclic phosphate and 5'-OH (RtcB) ligase as described herein. In one embodiment, the 3' ribozyme recognition sequence comprises a VS-S sequence as described herein.
[0273] In one embodiment, the ribozyme of step c) comprises a VS-Rz as described herein. In one embodiment, the VS-Rz recognizes VS-S and mediates cleavage of the VS-S from the one or more additional RNA molecules. In one embodiment, the cleavage produces a 3'P or 2'3'cP terminus. In one embodiment, steps b) to c) are repeated at least once to generate an RNA molecule encoding multiple domains. In one embodiment, the VS-Rz is removed prior to repeating step b).
[0274] In one embodiment, the last RNA molecule of step d) comprises a coding region encoding the last portion of the protein of interest. In one embodiment, the last RNA molecule comprises a 5' ribozyme. In one embodiment, the last RNA molecule comprises a coding region encoding the last portion of the protein of interest and a 5' ribozyme. In one embodiment, the 5' ribozyme catalyzes its own separation from the last RNA molecule, thereby producing a 5' OH terminus. In one embodiment, a ligase is provided to catalyze the attachment of the one or more additional RNA molecules to the last RNA molecule, thereby producing a complete RNA molecule encoding an N-terminal domain, one or more additional domains, and a C-terminal domain. In one embodiment, the ligase is an RNA 2', 3'-cyclic phosphate and 5'-OH (RtcB) ligase as described herein.
[0275] Any RNA molecule disclosed herein can be transcribed in vitro from a template DNA (referred to as an "in vitro transcription template"). The source of the DNA can be, for example, genomic DNA, plasmid DNA, phage DNA, cDNA, a synthetic DNA sequence, or any other suitable DNA source. In some embodiments, the in vitro transcription template encodes a 5' untranslated (UTR) region, contains an open reading frame, and encodes a 3' UTR and a polyA tail. The specific nucleic acid sequence composition and length of the in vitro transcription template will depend on the mRNA encoded by the template.
[0276] In one embodiment, the length of the 5'UTR is between 0 and 3000 nucleotides. The length of the 5' and 3'UTR sequences to be added to the coding region can be varied by various methods, including but not limited to designing PCR primers that anneal to different regions of the UTR. Using this method, one of ordinary skill in the art can modify the 5' and 3'UTR lengths required for optimal translation efficiency after transfection of the transcribed RNA.
[0277] The 5' and 3' UTRs can be naturally occurring endogenous 5' and 3' UTRs of the target gene. Alternatively, a UTR sequence that is not endogenous to the target gene can be added by incorporating the UTR sequence into the forward and reverse primers or by any other modification of the template. The use of a UTR sequence that is not endogenous to the target gene can be used to modify the stability and / or translation efficiency of the RNA. For example, it is known that AU-rich elements in the 3' UTR sequence can reduce the stability of the mRNA. Therefore, the 3' UTR can be selected or designed to increase the stability of the transcribed RNA based on the properties of the UTRs well known in the art.
[0278] In one embodiment, the 5'UTR may contain a Kozak sequence of an endogenous gene. Alternatively, when a 5'UTR that is not endogenous to the target gene is added by PCR as described above, a consensus Kozak sequence can be redesigned by adding a 5'UTR sequence. The Kozak sequence can improve the translation efficiency of certain RNA transcripts, but it does not seem that all RNAs need to achieve efficient translation. The requirement of many mRNAs for Kozak sequences is known in the art. In other embodiments, the 5'UTR may be derived from an RNA virus whose RNA genome is stable in the cell. In other embodiments, various nucleotide analogs can be used in the 3' or 5'UTR to prevent exonuclease degradation of the mRNA.
[0279] In order to synthesize RNA from a DNA template, a transcription promoter should be attached to the DNA template upstream of the sequence to be transcribed. When a sequence that acts as a promoter for RNA polymerase is added to the 5' end of the forward primer, the RNA polymerase promoter is incorporated into the PCR product upstream of the open reading frame to be transcribed. In one embodiment, the promoter is a T7 RNA polymerase promoter as described elsewhere herein. Other useful promoters include, but are not limited to, T3 and SP6 RNA polymerase promoters. The consensus nucleotide sequences of T7, T3, and SP6 promoters are known in the art.
[0280] In one embodiment, the mRNA has a cap at the 5' end and a 3' poly (A) tail, which determines ribosome binding, translation initiation, and mRNA stability in the cell. On a circular DNA template (e.g., plasmid DNA), RNA polymerase produces long tandem products that are not suitable for expression in eukaryotic cells. Transcription of plasmid DNA that is linearized at the 3' UTR end produces normal-sized mRNA that, when polyadenylated after transcription, is effective in eukaryotic transfection.
[0281] On a linear DNA template, bacteriophage T7 RNA polymerase can extend the 3' end of the transcript beyond the last base of the template (Schenborn and Mierendorf, Nuc Acids Res., 13:6223-36 (1985); Nacheva and Berzal-Herranz, Eur. J. Biochem., 270:1485-65 (2003)).
[0282] The conventional method for integrating polyA / T stretches into DNA templates is molecular cloning. However, polyA / T sequences integrated into plasmid DNA can lead to plasmid instability, which can be improved by using recombination-incompetent bacterial cells for plasmid propagation.
[0283] After in vitro transcription, the poly(A) tail of the RNA can be further extended using poly(A) polymerase (e.g., E. coli polyA polymerase (E-PAP) or yeast polyA polymerase). In one embodiment, increasing the length of the poly(A) tail from 100 nucleotides to 300 to 400 nucleotides results in an approximately two-fold increase in the translation efficiency of the RNA. In addition, attaching different chemical groups to the 3' end can increase mRNA stability. Such attachments can contain modified nucleotides / artificial nucleotides, aptamers, and other compounds. For example, poly(A) polymerase can be used to incorporate ATP analogs into the poly(A) tail. ATP analogs can further increase the stability of the RNA.
[0284] The 5' cap also provides stability for the mRNA molecule. In one embodiment, the RNA produced by the method includes a 5' cap 1 structure. Such a cap 1 structure can be produced using vaccinia capping enzyme and 2'-O-methyltransferase (CellScript, Madison, WI). Alternatively, a 5' cap is provided using techniques known in the art and described herein (Cougot et al., Trends in Biochem. Sci., 29: 436-444 (2001); Stepinski et al., RNA, 7: 1468-95 (2001); Elango et al., Biochim. Biophys. Res. Commun., 330: 958-966 (2005)).
[0285] Certain embodiments of the present invention can use a solid support consisting of an inert substrate or matrix (e.g., a glass slide, polymer beads, etc.), which has been functionalized, for example, by applying a layer or coating of an intermediate material comprising reactive groups that allows covalent attachment to biomolecules (e.g., polynucleotides). Examples of such supports include, but are not limited to, polyacrylamide hydrogels supported on an inert substrate (e.g., glass), particularly polyacrylamide hydrogels as described in WO 2005 / 065814 and US2008 / 0280773 (the contents of which are incorporated herein by reference in their entirety). In such embodiments, biomolecules (e.g., polynucleotides) can be directly covalently attached to the intermediate material (e.g., hydrogel), but the intermediate material itself can be non-covalently attached to a substrate or matrix (e.g., a glass substrate). The term "covalently attached to a solid support" should be correspondingly interpreted as including this type of arrangement.
[0286] As will be appreciated by those skilled in the art, the number of possible substrates is very large. Possible substrates include, but are not limited to, glass and modified or functionalized glass, plastics (including acrylics, polystyrene and copolymers of styrene with other materials, polypropylene, polyethylene, polybutylene, polyurethane, Teflon, TM etc.), polysaccharides, nylon or nitrocellulose, ceramics, resins, silica or silica-based materials (including silicon and modified silicon), carbon, metals, inorganic glasses, plastics, optical fiber bundles and a wide variety of other polymers.
[0287] In some embodiments, the solid support comprises microspheres or beads. Suitable bead compositions include, but are not limited to, plastics, ceramics, glass, polystyrene, methylstyrene, acrylic polymers, paramagnetic materials, thoria sol, carbon graphite, titanium dioxide, latex or cross-linked dextran (such as agarose), cellulose, nylon, cross-linked micelles and polytetrafluoroethylene, as well as any other material for solid supports outlined herein can be used. "Microsphere Detection Guide" from Bangs Laboratories, Fishers Ind. is a useful guide. In certain embodiments, the microsphere is a magnetic microsphere or bead.
[0288] The beads need not be spherical; irregular particles may be used. Alternatively or additionally, the beads may be porous. Bead sizes range from nanometers, i.e., 100 nm, to millimeters, i.e., 1 mm, with beads of about 0.2 micrometers to about 200 micrometers being preferred, and beads of about 0.5 micrometers to about 5 micrometers being particularly preferred, although smaller or larger beads may be used in some embodiments.
[0289] In one embodiment, the present invention relates to an in vitro method for assembling a full-length RNA viral genome. Exemplary RNA viruses include, but are not limited to, coronaviruses, paramyxoviruses, orthomyxoviruses, retroviruses, lentiviruses, alphaviruses, flaviviruses, rhabdoviruses, measles viruses, Newcastle disease viruses, and picornaviruses. In one embodiment, the method comprises providing a first RNA molecule comprising a first portion of an RNA viral genome and a 3' ribozyme. In one embodiment, the method comprises providing a second RNA molecule comprising a second portion of an RNA viral genome and a 5' ribozyme. In one embodiment, after cis-cleavage of the 3' and 5' ribozymes, as described herein, the first portion of the RNA viral genome and the second portion of the RNA viral genome have compatible ends for ligation. In one embodiment, the method comprises contacting the first RNA molecule and the second RNA molecule with a ligase as described herein, thereby producing a full-length RNA viral genome.

[0309] Experimental Examples
[0310] The present invention is further described in detail with reference to the following experimental examples. These examples are provided for illustrative purposes only and, unless otherwise indicated, are not intended to be limiting. Therefore, the present invention should in no way be construed as being limited to the following examples, but rather should be construed to encompass any and all variations that become apparent as a result of the teachings provided herein.
[0311] Without further description, it is believed that one of ordinary skill in the art can use the preceding description and the following illustrative examples to make and utilize the present invention and practice the claimed methods. Therefore, the following working examples should not be construed as limiting the remainder of the disclosure in any way.
[0312] Example 1: Ribozyme-mediated RNA assembly and expression in mammalian cells
[0313] Ribozymes (Rz) are small, catalytic RNA sequences capable of nucleotide-specific self-cleavage (Doherty and Doudna 2000). Ribozyme-mediated RNA cleavage generates distinct 3'-phosphate and 5'-hydroxyl termini that resemble substrates for ubiquitous RNA repair pathways across all three kingdoms of life. As demonstrated here, ribozyme-mediated cis-cleavage can be exploited for trans-splicing of independent RNA transcripts in mammalian cells, a method termed stitchR (stitch RNA). Remarkably, remodeling messenger RNA with stitchR allows for efficient translation and expression of full-length proteins in mammalian cells. As demonstrated, stitchR can be used to assemble protein-encoding functional domains or to deliver and express large protein-coding sequences via viral vectors. Furthermore, overexpression of the RNA 2',3'-cyclic phosphate and 5'-OH (RtcB) ligase enhanced stitchR activity in mammalian cells and was sufficient to catalyze stitchR activity in vitro. These data demonstrate a novel approach for scarless trans-splicing of functional RNAs in cells using ribozymes, which could be used for numerous research and therapeutic applications.
[0314] Autocatalytic RNA sequences are widespread in nature and catalyze a diverse range of biological processes, including intron splicing, rolling circle viral genome replication, and peptide bond formation (Weinberg et al., 2019). At least seven major ribozyme families with distinct sequence and structural features have been identified, including hammerhead (HH) ribozymes, hepatitis delta virus (HDV) ribozymes, Varkud satellite (VS) ribozymes, Sister ribozymes, Twister-sister ribozymes, hairpin ribozymes, Hatchet ribozymes, and Pistol ribozymes. The most extensively studied are members of the HH, HDV, and Twister ribozyme families, which, due to their small size and cleavage properties, have been used in vitro and in vivo to generate RNAs with precise ends without ribozyme sequences ( Figure 13 )(Ferre-D'Amare and Doudna 1996; Avis et al. 2012; Zhang et al. 2017).
[0315] In both prokaryotes and eukaryotes, most cellular RNAs, including messenger and long noncoding RNAs, are synthesized and spliced with 5'-phosphate (P) and 3'-hydroxyl (OH) termini. In contrast, unconventional cis-splicing of many tRNAs and the mRNA encoding the ER stress response protein XBP1 is catalyzed by enzymatic pathways that generate unique 5'-OH and 3'-P or 2'3' cyclic phosphate (cP) termini. Recent findings suggest that the ubiquitous RNA 2',3'-cyclic phosphate and 5'-OH (RtcB) ligase in mammals catalyzes unconventional RNA cis-splicing. Furthermore, RtcB and several other enzyme families may function to repair host cell RNAs damaged by stress or exogenous nuclear toxins. Because ribozyme-mediated cleavage results in similar terminal ends, ribozyme-cleaved RNAs may be subject to trans-splicing via endogenous RNA repair pathways.
[0316] Ribozyme-cleaved mRNA is trans-spliced and translated in mammalian cells
[0317] To determine whether ribozymes can be used for scarless trans-splicing of RNA in mammalian cells, two expression plasmids were designed containing non-overlapping N-terminal (Nt) and C-terminal (Ct) fragments of the fluorescent reporter gene GFP (Nt-GFP and Ct-GFP, respectively). Ribozymes were designed to catalyze their own removal from adjacent nucleotides of the GFP fragment, including the 3'HDV ribozyme on Nt-GFP and the 5'HH ribozyme on Ct-GFP ( Figure 1 A). Expression of either Nt or Ct GFP ribozyme RNA alone resulted in no detectable GFP fluorescence when transfected into mammalian COS-7 or HEK293T cells ( Figure 1 B). Notably, co-expression of RNA encoding Nt and Ct-GFP produced green fluorescence after 48 hours ( Figure 1 B). RT-PCR analysis and Sanger sequencing revealed that trans-splicing of separate Nt- and Ct-GFP RNAs occurred between the predicted ribozyme-catalyzed cleavage sites ( Figure 1 C and Figure 1 D). Furthermore, full-length GFP protein was detected in co-transfected cells by Western blotting ( Figure 1 E) These data demonstrate that the endogenous mammalian cellular RNA repair pathway is sufficient to catalyze the trans-splicing of independently ribozyme-processed RNAs, which are efficiently translated into full-length proteins. This RNA trans-splicing method has been named stitchR.
[0318] Effects of ribozyme sequence and type on ribozyme-mediated trans-splicing
[0319] To precisely quantify the relative amount of functional full-length protein produced by ribozyme-mediated trans-splicing in cells, two non-overlapping halves of firefly luciferase were used to generate a reporter gene ( Figure 2 A). Consistent with our previous findings, only co-transfection of the RNA encoding Nt-luciferase ribozyme and Ct-luciferase ribozyme resulted in trans-splicing and luciferase activity in cells ( Figure 2 B and Figure 2 C). Using this assay, we further characterized the effects of different HH and HDV ribozyme sequences on trans-splicing activity in mammalian cells. A 6-base pair (bp) overlap in the stem 1 HH ribozyme provided maximal luciferase activity and mutation of the HH catalytic residue abolished activity, consistent with previous reports on HH ribozyme activity characterized in vitro ( Figure 2 D). Furthermore, the luciferase activities of the genomic and antigenomic HDV ribozyme sequences were comparable, except for the smallest 56-nucleotide HDV ribozyme (HDV56), which had significantly lower activity ( Figure 2 E). Also consistent with previous reports, a C to U mutation of a nucleotide required for HDV catalysis resulted in a complete loss of luciferase activity ( Figure 2 E) These findings demonstrate that ribozyme-mediated trans-splicing activity is dependent on ribozyme cleavage in mammalian cells.
[0320] Use translational controllers and / or protein degradation sequences to prevent unwanted or truncated proteins from Nt or Ct vectors Express
[0321] The Nt or Ct RNA may undergo translation prior to ribozyme-mediated cleavage or, when expressed alone, may result in unwanted or truncated protein expression. To restrict expression of unspliced Nt or Ct vectors, the efficacy of previously characterized translational controllers of protein degradation sequences on the stability of vectors encoding full-length GFP was tested. Addition of the HDV ribozyme to the 3' end of GFP did not appear to alter GFP fluorescence ( Figure 3 A and 3B). To selectively block GFP expression, the effects of removing the protein degradation sequences hCL1-PEST, E1A-PEST, the vector's poly(A) sequence, or mimicking translation with a poly A tail to generate a poly K tail were tested ( Figure 3A and 3B). All degradation sequences were cloned in-frame with the GFP open reading frame, allowing translation via the HDV ribozyme sequence. Incorporation of hCL1-PEST showed a significant reduction in GFP fluorescence, while EF1a PEST did not. Deletion of the vector poly(A) sequence from the expression vector resulted in a complete loss of GFP expression, while translation via multiple poly(A) sequences to generate a poly K tail also resulted in reduced fluorescence.
[0322] For the Ct-encoded GFP reporter gene, inclusion of the 5′ HH ribozyme and deletion of the GFP start codon (ATG) still resulted in weak but detectable GFP expression despite the lack of a predicted upstream alternative ATG ( Figure 3 C and D). Further silent mutations within the N-terminal NTG codon in GFP (GFPcdn) further reduced GFP detection; however, weak fluorescence was still evident. Inclusion of the 5'UTR of the yeast GCN4 gene, encoding four small upstream ORFs that act as translational inhibitors, eliminated detectable GFP fluorescence. A smaller internal fragment of the GCN4 5'UTR encoding only these four uORFs was equally effective in preventing GFP expression. These data demonstrate that translational control of protein degradation sequences can be used to prevent unwanted protein expression from a single Nt or Ct vector.
[0323] These translational controllers or protein degradation sequences can be used in other dual-vector applications where it is desirable to limit the expression of unwanted or truncated proteins, such as dual AAV vector strategies that rely on homologous recombination to generate large protein-coding open reading frames.
[0324] Single and multiple trans-splicing of functional protein-coding RNAs
[0325] To determine whether ribozyme-mediated trans-splicing could be used to combine protein-coding functional domains in cells, RNA encoding four copies of the mitochondrial targeting sequence (Nt-4xMTS) and an open reading frame encoding full-length GFP lacking the ATG start codon (Ct-GFP) were generated ( Figure 4 A). Co-expression of these two independent RNAs resulted in strong expression of mitochondrial-localized GFP, which overlapped with the red fluorescent mitochondrial marker MitoTracker Red CMXRos ( Figure 4 B) These findings demonstrate that ribozyme-mediated trans-splicing can be used to rapidly combine two independent RNAs to express a specific functional fusion protein in cells.
[0326] Due to the three open reading frames in which proteins are translated, ribozyme-mediated trans-splicing and expression of multiple different functional proteins simultaneously may also be possible. By exploiting this property, trans-splicing of RNAs located in three different compatible open reading frames can be used to generate functional proteins. To demonstrate this functionality, an additional ribozyme pair was designed in reading frame 2 (F2), which encodes a myristoylated membrane targeting sequence (Nt-F2-Myr) and a red fluorescent protein (Ct-F2-RFP) ( Figure 4 C). These Nt and Ct vector pairs also include an hCL1-PEST protein degradation sequence and a GCN4 translation inhibition sequence to limit expression of truncated proteins from individual Nt and Ct vectors, respectively. In co-transfected cells, GFP fluorescence is highly specific to mitochondria, while RFP fluorescence is highly specific to membranes ( Figure 4 D), demonstrating the ability of this RNA trans-splicing method to generate diverse functional proteins in cells.
[0327] Optimized ribozymes enhance protein expression in ribozyme-mediated trans-splicing
[0328] Small sequence modifications can profoundly affect the catalytic activity of ribozymes by altering secondary structure, stability, or binding to metal ion cofactors. Using our trans-splicing luciferase reporter assay, we identified improved ribozyme types and sequence modifications that enhance trans-splicing luciferase reporter activity in mammalian cells ( Figure 16 The hammerhead variant ribozyme of RzB containing the tertiary stabilization motif (TSM) showed higher activity than the ribozyme without TSM ( Figure 16 A). Furthermore, when cloned 3' to Nt-Luc, the Twister (twst) ribozyme exhibited greater activity than the HDV ribozyme. Catalytic mutations within the twister ribozyme can similarly abolish luciferase activity ( Figure 16 B) and is dependent on the formation of the P1 stem ( Figure 16 C). Since Twister ribozymes require a U at position 1, this requirement may limit the design of scarless trans-splicing to sequences ending in U. Therefore, we tested whether nucleotide substitutions at position 1 could be tolerated and found that U1A did not show significantly different activity, while substitutions with U1C or U1G retained activity, but with reduced activity ( Figure 16 C).
[0329] Optimized splice donor and acceptor sequences enhance protein expression in ribozyme-mediated trans-splicing
[0330] Pre-mRNA splicing by the spliceosome has been shown to enhance mRNA translation by depositing factors that promote the first round of translation or by promoting RNA processing and export to the cytoplasm. Adding chimeric cis-splicing introns within transgenes has also been shown to promote transgenic protein expression. It was then investigated whether the trans-spliced RNA could undergo cis-splicing by the spliceosome and whether this would affect the translation and expression of the trans-spliced mRNA. To test this, splice donor (SD) and splice acceptor (SA) sequences were incorporated into the trans-splicing GFP reporter gene so that the trans-spliced RNA would reconstruct the chimeric intron ( Figure 5 A). Notably, the addition of SD and SA sequences robustly enhanced GFP fluorescence compared to the trans-spliced GFP reporter without SD or SA sequences ( Figure 5 B). RT-PCR and Sanger sequencing showed that Nt-GFP and Ct-GFP RNA containing SD and SA sequences were both trans- and cis-spliced, resulting in the recovery of the normal GFP open reading frame (data not shown). These data indicate that trans-splicing may occur in the nucleus and that subsequent cis-splicing is a useful strategy for enhancing expression of trans-spliced RNA.
[0331] Ribozyme-mediated trans-splicing and expression of large gene sequences for delivery using viral therapeutic vectors
[0332] Ribozyme-mediated trans-splicing can be used to deliver and express large protein-coding mRNAs that exceed the packaging size limit of therapeutic viral gene therapy vectors such as AAV. Figure 6 A). This may help restore expression of large genes that are mutated in many human monogenic diseases, such as dystrophin (Dys) in Duchenne muscular dystrophy (DMD), CFTR in cystic fibrosis (CF), and factor VIII (F8) in hemophilia A. In a cell-based transfection assay, vectors encoding Nt and Ct split μdystrophin co-expressed with a C-terminal GFP tag were trans-spliced in mammalian cells ( Figure 6 B and Figure 6 C) and is localized to the membrane ( Figure 6 D) These data demonstrate the feasibility of reconstructing and expressing large protein-coding genes using ribozyme-mediated trans-splicing.
[0333] Lentiviral delivery of ribozyme-enabled RNA for trans-splicing in cells deliver
[0334] The autocatalytic self-cleavage of ribozymes may hinder the packaging of ribozyme-encoding RNA by positive-sense RNA viruses (such as commonly used gamma-retroviruses and lentiviral vectors). To circumvent this potential problem, the GFP expression cassette with Nt and Ct split was encoded on the negative strand of the third-generation lentiviral vector backbone ( Figure 7 A). Lentiviral particles were generated for Nt and Ct vectors, respectively, and then used to transduce HEK293T cells. Cells transduced with both Nt-GFP and Ct-GFP showed green fluorescence expression, while cells transduced with either Nt-GFP or Ct-GFP alone showed no detectable fluorescence ( Figure 7 B) These data demonstrate that lentiviral vectors are capable of delivering and expressing ribozymes encoding RNAs for trans-splicing.
[0335] This approach can also be used to deliver large gene sequences that exceed the packaging size of these viral vectors, such as Dys( Figure 7 C). Ribozyme-mediated trans-splicing may also allow the safe manipulation or reconstruction of viral genomes, such as lentiviral or large coronavirus RNA genomes.
[0336] Safe manipulation, delivery, and expression of toxic or antiviral genes using viral vectors
[0337] Ribozyme-mediated trans-splicing can also allow for the safe manipulation or reconstitution of toxic or antiviral proteins that might inhibit the production of lentiviral particles in mammalian packaging cells. These include a number of cell suicide genes, such as the translation inhibitory diphtheria toxin A (DTA) ( Figure 8 A). We demonstrate that vectors encoding split DTA sequences, upon trans-splicing and expression, inhibit co-expression of a CS2GFP reporter construct, consistent with a translational repressive role for DTA in mammalian cells ( Figure 8 B).
[0338] Enzymes for enhancing or inhibiting ribozyme-mediated trans-splicing
[0339] Many families of enzymes have been suggested to link 5'-OH and 3'-P or 2'3' cyclic phosphate (cP) termini, the most notable being RtcB, which has been found to be conserved across all three domains of life. Human codon-optimized RtcB orthologs from eukaryotic (H. sapiens), bacterial (E. coli), and archaeal (P. horikoshii) species were cloned and co-expressed to measure their effects on the activity of a trans-splicing luciferase reporter gene. Interestingly, co-expression of RtcB from P. horikoshii resulted in an enhancement of luciferase activity (4.5-fold), whereas the human and bacterial orthologs showed modest or no enhancement ( Figure 9 ).
[0340] Other enzyme families have been shown to regulate these RNA ends. Interestingly, expression of T4 polynucleotide kinase (T4 PNK), which functions as a 5'-hydroxykinase, 3'-phosphatase, and 2',3'-cyclic phosphodiesterase, significantly inhibited luciferase activity ( Figure 9These data indicate that coexpression of exogenous enzymes can enhance or inhibit ribozyme-mediated trans-splicing in mammalian cells.
[0341] RtcB is sufficient to catalyze ribozyme-mediated RNA trans-splicing in vitro
[0342] Due to their nucleotide-specific cleavage, ribozymes have been widely used to generate precise RNA ends in vitro. We next sought to determine whether ribozymes could be used to direct trans-splicing of independently synthesized RNA in vitro. In vitro RNA transcription of Nt- and Ct-luciferase-ribozyme reporter gene constructs using T7 RNA polymerase revealed that the addition of recombinant E. coli RtcB was both necessary and sufficient to catalyze trans-splicing detected using RT-PCR. Figure 10 A and Figure 10 B). Similarly, RNA encoding the domain of the spider silk protein Spidroin was designed ( Figure 10 C). Spidroin is the main component of spider dragline silk, a material highly prized for its tensile properties, but difficult to synthesize in heterologous systems due to the protein's highly repetitive nature. Spidroin naturally consists of multiple A and Q repeats flanked by conserved N-terminal (N1L) and C-terminal (N3R) domains. Following in vitro synthesis of spidroin RNA using T7 polymerase, addition of recombinant RtcB ligase from Escherichia coli was found to be sufficient to catalyze trans-ligation of RNAs encoding the ribozyme-cleaved N1L and N3R, as detected by RT-PCR and Sanger sequencing ( Figure 10 D).
[0343] Controlled tandem trans-splicing of RNAs encoding multidomain proteins
[0344] We next examined whether the addition of a third RNA encoding an AQ fusion domain with flanking ribozymes would result in tandem repeat assembly, albeit uncontrolled ( Figure 11 A). Although directed trans-splicing between each individual RNA could be detected, assembly of three or more independent RNA fragments could not be detected (data not shown). This is likely due to the rapid circularization of RNAs containing ends compatible with RtcB ligation. As an alternative, the use of transactivated VS ribozymes has the potential to allow the sequential and controlled assembly of RNA sequences in vitro ( Figure 11 B and Figure 11C). In this approach, the 3'-terminal RNA ribozyme is only suitable for ligation after addition and trans-cleavage by VS-Rz. Because the VS-Rz transactivating ribozyme RNA is not covalently attached, the stepwise addition of stitchR-compatible RNA, VS-Rz, and RtcB ligase allows for controlled tandem assembly of RNA sequences, which may facilitate the assembly of repetitive RNAs encoding biologically or industrially important proteins (e.g., synthetic spider silk, elastin, collagen, etc.).
[0345] Trans-splicing of endogenous RNA using trans-cleaving ribozymes: therapeutic applications for correcting disease-causing mutations
[0346] Ribozymes are autocatalytic RNAs that cleave in cis to generate unique RNA ends that we have shown are trans-spliced and subsequently expressed in mammalian cells ( Figure 12 A). Notably, cis-cleaving ribozymes can be engineered to cleave in trans, allowing the target RNA to be cleaved in a nucleotide-specific manner, generating similar RNA ends ( Figure 12 B)(Carbonell et al. 2011; Webb and Luptak 2018). Thus, trans-cleaving ribozymes can be used to catalyze scarless trans-splicing of RNA in cells or in vitro. This approach can be used for numerous applications, a major one of which is the deletion of disease-causing mutations in gene transcripts by targeting mutation flanking sequences in exonic or intronic sequences ( Figure 12 C and Figure 12 D).
[0347] In summary, this article demonstrates that ribozyme-mediated cleavage of independent RNAs expressed in cells is efficiently assembled and can be translated in mammalian cells. This method, referred to herein as stitchR, can be used as a new method for the combinatorial assembly of functional RNAs and proteins for basic and therapeutic applications. Due to the autocatalytic nature of ribozymes and the endogenous RNA repair pathways present in cells, stitchR only requires the expression of a single RNA for trans-splicing and translation to occur in cells. In vitro, the RtcB ligase has been shown to be sufficient for trans-splicing, and since RtcB is ubiquitous and widely expressed in all three kingdoms of life, stitchR has the potential to become a useful method in many different organisms.
[0348] The robustness of this system relies on the efficient and precise nature of ribozyme-mediated RNA cleavage, which produces reliable and accurate nucleotide-specific termini that are crucial for restoring protein-coding open reading frames. Furthermore, the ability to generate RNA using ribozymes that completely catalyze their own removal allows for scarless assembly, resulting in RNA that is essentially indistinguishable from its native counterpart.
[0349] While ribozyme cleavage has been extensively studied in vitro, in vivo ribozyme cleavage is less understood and is thought to be influenced by the availability of metal ions required for folding and catalysis through interactions with RNA-binding proteins. StitchR serves as an indirect readout for ribozyme-mediated cleavage, and interestingly, we found that it is significantly affected by variations in ribozyme sequence and structure. This suggests that optimization of ribozyme cleavage may be a useful approach for enhancing stitchR activity in vivo. Further analysis of the influence of RNA repair pathway components such as RtcB, RtcA, and Archease may also serve as important factors in regulating stitchR activity.
[0350] Ribozymes have naturally evolved to function in cis to promote their self-cleavage, however, many ribozyme families (particularly HDV and HH) have been engineered to cleave target RNAs in trans. It is noteworthy here that combining trans-cleaving ribozymes with stitchR can further allow for a robust RNA cleavage and repair method to be performed in cells or in vitro. This approach can be used as a nucleotide-specific "cut and paste" method for RNA, which may help generate RNA diversity or help remove certain harmful mutations in pathogenic RNAs.
[0351] Example 2: Trans-splicing and expression of RNA can be induced using transactivated ribozymes
[0352] Most ribozymes are autocatalytic and require only metal ions as cofactors, which are readily found in the biological environment, which facilitate folding and chemical catalysis. Varkud satellite (VS) ribozymes can be used for scarless trans-splicing if the donor RNA ends with a G nucleotide. Interestingly, the VS ribozyme can be modified to allow transactivation of the ribozyme to induce catalysis (Guo and Collins 1995; Ouellet et al. 2009). When split into two components, the small VS stem-loop (VS-S) is insufficient to induce cis-cleavage alone, however, the addition of the remaining sequence VS-Rz promotes efficient cleavage of VS-S ( Figure 14 A). This transactivation feature may allow for inducible ribozyme-mediated trans-cleavage, where the addition of a VS-Rz sequence is required to enable VS-S cleavage on an Nt donor RNA, which is then suitable for trans-splicing with a Ct acceptor RNA containing a 5'-OH terminus ( Figure 14 B) The VS-Rz sequence, which contains typical 5'-P- and 3'-OH RNA ends, cannot participate in trans-splicing and therefore can serve as a multi-turnover catalyst for the reaction.
[0353] The ability to control ribozyme-mediated cleavage, such as by the addition of a desired transactivation sequence (such as VS-Rz), could allow for the controlled addition of variable or non-variable RNA sequences to generate synthetic repetitive RNAs ( Figure 14C). One approach is to generate RNAs with unique N-terminal domains, unique C-terminal domains, and internal variable or non-variable "repeat" domains. This approach requires that both the N-terminal and C-terminal RNAs contain a single ribozyme at the 3' and 5' termini, respectively. Internally repeated RNAs require ribozymes at both the 5' and 3' termini to function as both acceptors and donors during trans-splicing. However, the addition of ribozymes to both ends of the RNA or to RNAs with both a 3'-P and a 5'-OH leads to cyclization by ligases such as RtcB (Desai et al., 2015), thereby preventing participation in the growing linear chain. However, the use of inducible transactivating ribozymes can control RNA domain synthesis by adding and removing VS-Rz and RtcB ligases to gradually ligate the 5' and 3' termini ( Figure 14 C). This approach can be used to generate highly repetitive RNA sequences that can then be translated to produce synthetic repetitive proteins (such as those that make up hydrogels, synthetic spider silk, or collagen), which are difficult to produce and encode as DNA due to recombinant methods. These methods may be useful for drug delivery, biomaterials, or the production of industrial materials (Chambre et al., 2020).
[0354] Example 3: Generation of Stable Synthetic Intron Sequences Using Ribozymes
[0355] When one RNA contains a 3' ribozyme and the other contains a 5' ribozyme, ribozyme-mediated trans-splicing can occur between the two independent RNAs ( Figure 15 A). However, it has been demonstrated that both ribozymes can mediate their own scarless removal when transcribed in cis within the same RNA ( Figure 15 B). This approach also generates two independent RNAs with 3'-P and 5'OH ends, which can undergo trans-splicing and translation in cells ( Figure 15 B) This can also be achieved in vitro by adding a ligase such as RtcB.
[0356] The intronic sequences produced by the ribozyme also contain compatible 5'-OH and 3'-P termini and can be cis-spliced or circularized, which is a common readout of RtcB ligase activity in vitro. Unlike the rapidly degradable lariat RNA produced by the spliceosome during exon splicing, RNA loops are considered highly stable because they no longer contain 5' or 3' termini and are therefore not degraded by RNA exonucleases. A cargo sequence that can contain any number of functional or useful RNAs (such as microRNAs, CRISPR guide RNAs, etc.) or gene expression sequences can be inserted as "cargo" between the two ribozymes ( Figure 15C). This approach can be used to co-deliver and express useful RNA sequences during ribozyme-mediated trans-splicing and expression. If one of the internal ribozymes does not require bilateral flanking sequences for activity, such as for the 5' HDV ribozyme, the RNA loop can exist in both circular and re-cleaved linear forms ( Figure 15 C). When VS-S is used instead of HDV, the system can be made inducible, requiring delivery or expression of VS-Rz. Using ribozymes that require bilateral flanking sequences for cleavage (such as the HH ribozyme), the cleavage can be designed so that RNA circularization of the cargo RNA is unidirectional ( Figure 15 D).
