Abstract
Description
[Technical Field]
[0001] The present invention relates to the induction of cell lethality in cancer cells. [Background technology]
[0002] Many conventional anti-cancer therapies, such as radiation therapy or chemotherapy, target dividing cells and are highly toxic to non-cancerous cells, causing severe side effects.
[0003] A therapeutic strategy based on synthetic lethal interactions, i.e., inducing cell death by disrupting two genes simultaneously rather than separately, allows for highly efficient and selective targeting of tumor cells while protecting non-cancerous cells.
[0004] There is a need for new and improved cancer therapeutics based on synthetic lethal interactions. Summary of the Invention
[0005] We found that depletion of Fanconi anemia complementation group (FANC) proteins, for example by siRNA, is selectively lethal to SETD2-deficient cancer cells, and therefore FANC antagonists may be useful in treating SETD2-deficient cancers.
[0006] A first aspect of the present invention provides a method of treating cancer in an individual in need thereof, the method comprising reducing the expression or activity of FANC in the individual, wherein the cancer is a SETD2-deficient cancer.
[0007] A second aspect of the present invention provides a FANC antagonist for use in a method of treating SETD2-deficient cancer.

[0009] A fourth aspect provides a method for screening for a compound that induces cell death in SETD2-deficient cancer cells, comprising determining binding of a test compound to FANC, wherein binding to FANC indicates that the compound induces cell death in SETD2-deficient cells.
[0010] A fifth aspect provides a method for screening for a compound that induces cell death in SETD2-deficient cancer cells, comprising determining the effect of a test compound on the expression or activity of FANC, wherein a decrease in the expression or activity of FANC suggests that the compound induces cell death in SETD2-deficient cancer cells.
[0011] A sixth aspect provides a method for determining the responsiveness of a cancer in an individual to treatment with a FANC antagonist, the method comprising determining the presence of one or more SET2D-deficient cancer cells in a sample obtained from the individual, wherein the presence of one or more SETD2-deficient cancer cells in the sample indicates that the cancer will be responsive to treatment with a FANC antagonist.
[0012] A seventh aspect provides a method for selecting an individual having a SETD2-deficient cancer for treatment with a FANC antagonist, the method comprising identifying cancer cells obtained from the individual as being deficient in SETD2 relative to normal cells.

[0017] The present invention relates to the discovery that reduced or absent expression or activity of FANC protein in SETD2-deficient cancer cells induces cell death, which may be useful in the treatment of cancerous conditions, such as cancerous conditions characterized by a SETD2 deficiency.
[0018] Su(var), Enhancer of zeste, Trithorax (SET)-domain containing protein 2 (SETD2; EC:2.1.1.359; Gene ID:29072) is a histone methyltransferase responsible for the trimethylation of histone H3 at lysine 36 (i.e., H3K36me3). SETD2-mediated H3K36me3 is introduced sequentially during transcription elongation and is important for maintaining nucleosome occupancy, DNA double-strand break repair, RNA splicing, and transcription termination (Li J, et al. Oncotarget. 2016; 7(31):50719-50734; de Almeida SF, Carmo-Fonseca M. Trends Biochem Sci. 2012; 37(6):248-253; Carvalho S, et al. Nucleic Acids Res. 2013; 41(5):2881-2893; Carvalho S, et al. Elife. 2014; 3:e02482; Grosso AR, et al. Elife. 2015; 4:e09214). Thus, loss of SETD2 causes genomic instability, and SETD2 is mutated in a variety of human cancers (Fahey CC, et al. Cold Spring Harb Perspect Med. 2017; 7(5):a026468).
[0019] The human gene encoding SETD2 has 25 exons and is located at 3p21.31. The reference coding sequence of human SETD2 is set forth in SEQ ID NO: 9. Other reference human SETD2 coding sequences have database accession numbers NM_001349370.3 and NM_014159.7. The SETD2 coding sequences described herein may comprise a reference nucleotide sequence such as SEQ ID NO: 9 or a variant thereof.
[0020] A SETD2-deficient cancer may comprise or consist of one or more cancer cells in which SETD2 expression and / or activity is reduced or absent. SETD2 expression and / or activity may be reduced or absent in cancer cells due to one or more alterations in one or both alleles of the SETD2 gene, such as one or more mutations, translocations, or deletions, or due to epigenetic modifications that impair SETD2 expression or activity, such as changes in DNA or histone methylation, or due to mutation(s) in genes encoding regulators, such as HOX transcript antisense RNA.
[0021] Mutations may include nonsynonymous mutations, including frameshift, missense, nonsense, splice site, nonstop, and translation start site changes; truncating mutations, including nonsense, nonstop, frameshift deletions, frameshift insertions, and splice site changes; and in-frame mutations, including in-frame deletions and in-frame insertions. Mutations in the gene encoding SETD2 can result in the production of mutant polypeptides with altered activity, such as reduced or lost activity. Genomic translocations or chromosomal rearrangements (e.g., inversions) involving the SETD2 gene and / or deletion of part or all of the SETD2 gene can also result in loss of functional SETD2 protein. Epigenetic changes, such as DNA methylation or histone (de)acetylation and (de)methylation, can also result in reduced or lost SETD2 activity.
[0022] The presence of one or more mutations in one or both alleles of the SETD2 gene can be determined by detecting the presence of a nucleic acid sequence from the SETD2 gene containing one or more mutations, or by detecting a mutant polypeptide encoded by the gene, in one or more cells of a test sample obtained from the individual.
[0023] A variety of methods are available for determining the expression and / or activity of SETD2 in a sample obtained from an individual.
[0024] Genetic testing such as DNA sequencing, exome sequencing, comparative genomic hybridization, in situ hybridization (e.g., fluorescent in situ hybridization (FISH)), PCR, RT-PCR, karyotyping, classical and molecular cytogenetics, or molecular testing such as enzyme activity assays, complementation assays, Western blot or immunofluorescence of SETD2 or H3K36me3, bisulfite sequencing, can reveal one or more mutations (including one or more nucleotide mutations, deletions, translocations, inversions, chromosomal rearrangements, or epigenetic changes) in the SETD2 gene or insufficient production or activity of the SETD2 protein.
[0025] The nucleic acid, which may be genomic DNA, RNA, or cDNA, or an amplified region thereof, can be sequenced to identify or determine the presence of one or more mutations in the nucleic acid. Mutations can be identified by comparing the obtained sequence with database sequences of the component, as defined above. In particular, the presence of one or more mutations that cause abrogation or loss of function of SETD2 can be determined. The presence of one or more of the mutation types described above indicates reduced or lost activity.
[0026] Sequencing can be performed using any one of a variety of standard techniques. Sequencing of the amplified products can involve, for example, precipitation with isopropanol, resuspension, and sequencing using a TaqFS+ dye terminator sequencing kit. Extension products can be electrophoresed on an ABI 377 DNA sequencer, and data analysis can be performed using Sequence Navigator software.
[0027] A specific amplification reaction, such as polymerase chain reaction (PCR), using one or more pairs of primers can be conveniently used to amplify a region of interest within a nucleic acid sequence, e.g., a portion of the sequence suspected of containing a mutation or polymorphism. As described above, the amplified nucleic acid can then be sequenced and / or tested in any other manner to determine the presence or absence of a mutation or polymorphism that reduces or eliminates the expression and / or activity of SETD2.
[0028] Furthermore, once the nucleic acid of an individual or sample has been sequenced, the sequence information is preserved and can then be retrieved without reliance on the original nucleic acid itself, allowing sequence variations or mutations to be identified, for example, by scanning databases of sequence information using sequence analysis software.
[0029] In some embodiments, a cancer can be identified as being deficient in SETD2 by assessing the level of SET2D expression or activity, which can be determined, for example, by Western blot, ELISA, RT-PCR, nucleic acid hybridization, or karyotype analysis.
[0030] Mutations and polymorphisms associated with SETD2-deficient cancers can also be detected at the protein level, for example, by detecting the presence of mutant polypeptides by immunohistochemistry.
[0031] Furthermore, because SETD2 is the only enzyme responsible for H3K36me3 (Edmunds et al., (2008) (The EMBO journal 27(2):406-420)), determining the level of H3K36me3 in a sample obtained from an individual can be used to identify cancer as a SETD2-deficient cancer. The level of H3K36me3 can be measured using immunofluorescence or Western blot. A decrease in the level of the trimethylation mark H3K36me3 suggests a decrease or loss of SETD2 activity and / or expression.
[0032] The sample may be a sample of cancer cells, which may be obtained from an individual using conventional techniques.
[0033] SETD2-deficient cancers can be treated by reducing or eliminating the expression or activity of Fanconi anemia complementation group (FANC) proteins, as described herein. FANC proteins are components of the FANC / BRCA pathway, which is involved in DNA replication and DNA damage response. FANC proteins may include FANCA, FANCC, FANCG (XRCC9), FANCJ, FANCE, FANCF, FANCP (SLX4), FANCD1 (BRCA2), FANCI, FANCL, FANCM, FANCN (PALB2), FANCO (RAD51C), FANCQ (ERCC4), FANCS (BRCA1), FANCT (UBE2T), FANCU (XRCC2), FANCV (REV7), FANCW (RFWD3), FANCB, FANCR, and (RAD51).
[0034] Preferred FANC proteins can include components of the FA core ubiquitin ligase complex, such as FANCA, FANCB, FANCC, FANCE, FANCF, FANCG, and FANCL. Other preferred FANC proteins can include components of the heterodimeric complex (ID complex) that is monoubiquitinated by the FA core complex, such as FANCD2 and FANCI.
[0035] In some preferred embodiments, the FANC protein is FANCM.
[0036] In other preferred embodiments, the FANC protein is FANCD2 or FANCI.
[0037] Fanconi anemia group M protein (FANCM) is an ATP-dependent DNA helicase / translocase (EC 3.6.4.13) involved in homologous recombination, meiosis, and DNA repair. FANCM may be human FANCM. The human gene encoding the FANCM polypeptide (Gene ID: 57697) has 25 exons and is located at 14q21.2. A reference human FANCM amino acid sequence is shown in SEQ ID NO: 1. Other reference human FANCM amino acid sequences have database accession numbers NP_001295062.1, NP_1295063.1, and NP_065988.1. The FANCM polypeptides or proteins described herein may comprise a reference amino acid sequence such as SEQ ID NO: 1 or a variant thereof.
[0038] The Fanconi anemia group D2 protein (FANCD2) is a member of the heterodimeric ID (or FANCD2 / FANCI) complex, which is monoubiquitinated by the FA core complex and loads onto chromatin in response to DNA damage. FANCD2 may be human FANCD2. The human gene encoding the FANCD2 polypeptide (Gene ID: 2177) has 45 exons and is located at 3p25.3. A reference human FANCD2 amino acid sequence is set forth in SEQ ID NO: 5. Other reference human FANCD2 amino acid sequences have database accession numbers NP_001018125.1, NP_001306913.1, NP_001351182.1, NP_001361183.1, NP_001361184.1, and NP_149075.2. The FANCD2 polypeptides or proteins described herein may comprise a reference amino acid sequence such as SEQ ID NO: 5 or a variant thereof.
[0039] The Fanconi anemia group I protein (FANCI) is a member of the heterodimeric ID (or FANCD2 / FANCI) complex, which is monoubiquitinated by the FA core complex and localized to chromatin in response to DNA damage, such as interstrand crosslinks. FANCI may be human FANCI. The human gene encoding the FANCI polypeptide (Gene ID: 55215) has 41 exons and is located at 15q26.1. A reference human FANCI amino acid sequence is set forth in SEQ ID NO: 7. Other reference human FANCI amino acid sequences have database accession numbers NP_001363839.1, NP_001363840.1, and NP_060663.2. The FANCI polypeptides or proteins described herein may comprise a reference amino acid sequence, such as SEQ ID NO: 7, or a variant thereof.
[0040] As used herein, a variant of a reference amino acid sequence is an amino acid sequence that has at least 80% sequence identity, at least 85% sequence identity, at least 90% sequence identity, at least 95% identity, or at least 98% identity to a reference amino acid sequence such as SEQ ID NO:1, SEQ ID NO:5, or SEQ ID NO:7.
[0041] A reference human FANCM-encoding nucleotide sequence is set forth in SEQ ID NO: 2. Other reference human FANCM-encoding sequences have database accession numbers NM_001308133.1, NM_001308134.1, and NM_020937.4. The FANCM nucleotide sequences described herein can include the nucleotide sequence of a reference human FANCM-encoding sequence, such as SEQ ID NO: 2, or a variant thereof.
[0042] A reference human FANCD2-encoding nucleotide sequence is set forth in SEQ ID NO: 6. Other reference human FANCD2-encoding sequences have database accession numbers NM_001319984.2, NM_001374253.1, NM_001374254.1, NM_001374255.1, and NM_0033084.6. The FANCD2 nucleotide sequences described herein may include the nucleotide sequence of a reference human FANCD2-encoding sequence, such as SEQ ID NO: 6, or a variant thereof.
[0043] A reference human FANCI-encoding nucleotide sequence is set forth in SEQ ID NO: 8. Other reference human FANCI-encoding sequences have database accession numbers NM_001376910.1, NM_001376911.1, and NM_018193.3. The FANCI nucleotide sequences described herein can include the nucleotide sequence of a reference human FANCI-encoding sequence, such as SEQ ID NO: 8, or a variant thereof.
[0044] Reference amino acid sequences and reference coding sequences for other FANC proteins are available in public databases.
[0045] Sequence identity is generally defined with reference to the algorithm GAP (Wisconsin GCG package, Accelerys Inc, San Diego, USA). GAP aligns two complete sequences using the Needleman and Wunsch algorithm, which maximizes the number of matches and minimizes the number of gaps. Generally, the default parameters are used: gap creation penalty = 12 and gap extension penalty = 4. Although the use of GAP may be preferred, other algorithms may also be used, such as BLAST (using the method of Altschul et al. (1990) J. Mol. Biol. 215: 405-410), FASTA (using the method of Pearson and Lipman (1988) PNAS USA 85: 2444-2448), SSEARCH (Smith and Waterman (1981) J. Mol. Biol. 147: 195-197;), HMMER3 (Johnson LS et al BMC Bioinformatics. 2010 Aug 18; 11():431), or the TBLASTN program of Altschul et al. (1990) (cited above), generally using default parameters (e.g., Pearson Curr Prot Bioinformatics (2013) Chapter 3 Univ. 3.1). doi:10.1002 / 0471250953.bi0301s42). In particular, the psi-Blast algorithm can be used (Altschul et al. Nucl. Acids Res. (1997) 25 3389-3402). Sequence identity and similarity can also be determined using Genomequest™ software (Gene-IT, Worcester MA USA). Sequence comparison is preferably performed over the entire length of the relevant sequences described herein.
[0046] In other embodiments, for example, when the individual to be treated is a non-human mammal, the FANC can be a non-human mammalian FANC. Reference non-human FANC amino acid sequences and reference non-human FANC coding sequences are available in public databases.
[0047] It is shown herein that reduced expression or activity of FANC, for example, reduced expression or activity of FANCM, FANCD2, and / or FANCI, reduces the viability of SETD2-deficient cancer cells. Reduced or absent expression or activity of the FANC protein described herein can reduce or inhibit the activity of the FANC / BRCA pathway, which repairs DNA interstrand crosslinks (ICLs) (see, e.g., Renaudin et al. Genes 202011(5) 585).
[0048] FANC activity in an individual can be reduced by administering a FANC antagonist that reduces the expression or activity of the FANC protein. The FANC antagonist can be one that can inhibit the activity of the FANC protein, such as a FANC inhibitor, or one that can reduce the activity of the FANC protein by degrading the FANC protein, such as a FANC degradation inducer such as a PROTAC or molecular glue, or one that can reduce or inhibit the expression of the FANC protein, such as a suppressor nucleic acid or targeted nuclease.
[0049] In some embodiments, the FANC antagonist may be a FANCM antagonist that reduces the expression or activity of a FANCM protein.
[0050] In other embodiments, the FANC antagonist may be a FANCD2 antagonist that reduces the expression or activity of a FANCD2 protein.
[0051] In other embodiments, the FANC antagonist may be a FANCI antagonist that reduces the expression or activity of a FANCDI protein.
[0052] FANC inhibitors may include, for example, small chemical molecules, e.g., non-polymeric organic compounds having a molecular weight of 900 daltons or less. For example, a suitable small molecule FANCM inhibitor can inhibit ATP binding to the ATPase domain of FANCM, DNA binding to the translocase domain of FANCM, and / or FANCM binding to binding partners such as MHF, FAAP24, BLM, RMI, and Topo IIIα. A suitable small molecule FANCD2 or FANCI inhibitor can inhibit monoubiquitination of FANCD2 or FANCI, binding of FANCI to FANCD2, or phosphorylation of FANCI or FANCD2 by ATR / ATM. Techniques suitable for rational design of small molecule inhibitors based on structural analysis of FANC proteins such as FANCM, FANCD2, and FANCI are known in the art.
[0053] Examples of FANC inhibitors include biomolecules that specifically bind to FANC proteins. Examples of FANCM inhibitors include biomolecules that specifically bind to FANCM. In some embodiments, the biomolecules can specifically bind to the DEAH helicase-like domain corresponding to residues 83 to 591 of SEQ ID NO: 1.
[0054] Biomolecules may include peptides. Peptides may comprise or consist of 5 to 40 amino acids, e.g., 6 to 10 amino acids, and may be derived from the above-described FANC proteins, e.g., FANCM, FANCD2, or FANCI, or their binding partners. Biomolecules may also include antibodies, antibody fragments, and antibody derivatives, as well as non-immunoglobulin binding molecules, such as aptamers, trinectins, anticalins, Kunitz domains, transferrin, nurse shark antigen receptor, and sea lamprey leucine-rich repeat proteins. Techniques suitable for generating biomolecules that specifically bind to FANC proteins are known in the art.
[0055] FANC degraders include small molecule ligands that regulate protein interactions in the ubiquitin-proteasome system. FANC degraders may include proteolysis-targeting chimeric molecules (PROTACs). PROTACs are heterobifunctional molecules containing a ligand for a protein of interest (POI) conjugated via a linker to a ligand that recruits an E3 ubiquitin ligase (E3). The PROTAC promotes the formation of a ternary complex between the POI and the E3, initiating degradation, followed by ubiquitination and degradation of the POI by the ubiquitin-proteasome system. The PROTAC can then be recycled to target another POI. This catalytic process reduces target levels (Sun, X., et al. Sig Transduct Target Ther 4, 64 (2019); Schneider, M., et al. Nat Rev Drug Discov 20, 789-797 (2021)). Thus, FANC degradation inducers include PROTACs that include a ligand for a FANC protein, such as FANCM, FANCD2, or FANCI, linked to a ligand that recruits an E3 ubiquitin ligase (E3). Methods for designing PROTACs are known in the art (see, e.g., Paiva SL, Curr Opin Chem Biol. 2019; 50:111-119).
[0056] FANC degradation inducers include molecular glues, which are linkerless scaffolds that induce proximity through direct ligase-target protein-protein interactions. The molecular glues insert into the natural protein-protein interaction (PPI) interface of the POI, inducing interaction between E3 ubiquitin ligase and the target protein, leading to target protein degradation (Kozicka Z, et al., Cell Chem Biol. 2021; 28(7):1032-1047; Zhao L, et al., Signal Transduct Target Ther. 2022; 7(1):113; Simonetta KR, et al. Nat Commun. 2019; 10(1):1402). Therefore, FANC degradation inducers include molecular glues that induce interaction between FANCM and E3 ubiquitin ligase. Methods for designing molecular glues are known in the art (see, for example, Kozicka Z, et al., Cell Chem Biol. 2021; 28(7):1032-1047).
[0057] Suitable E3 ligase ligands and methods for discovering E3 ligase ligands are known in the art (see, for example, Ishida T, Ciulli A. SLAS Discov. 2021; 26(4):484-502).
[0058] The terms "FANC antagonist" and "FANC inhibitor," as used herein, refer to compounds that antagonize or inhibit components of the FANC / BRCA pathway (FANC proteins), and may include "FANCM antagonists," "FANCM inhibitors," "FANCD2 antagonists," "FANCD2 inhibitors," as well as "FANCI antagonists" and "FANCI inhibitors."
[0059] The terms "FANC antagonist" and "FANC inhibitor" as used herein include FANCM antagonists, including pharmaceutically acceptable salts and solvates of these compounds.
[0060] Suitable antagonists for reducing or suppressing expression of a FANC protein, such as FANCM, FANCD2, or FANCI, include suppressor nucleic acids, targetable nucleases, and nucleic acids encoding such agents. The suppressor nucleic acid or nucleic acid encoding a targetable nuclease may be contained in a vector.
[0061] Suitable expression vectors are known in the art and include viral vectors such as retroviral vectors, adenoviral vectors, adeno-associated viral vectors, lentiviral vectors, vaccinia vectors or herpes vectors.
[0062] Expression of active FANC protein can be reduced or abolished by a suppressor nucleic acid or targetable nuclease compared to control cells. That is, transcription of the FANC gene and / or translation of FANC mRNA can be reduced or abolished, such that cells treated with the suppressor nucleic acid or targetable nuclease lack or have reduced amounts of active FANC protein compared to control cells. Reducing the amount of active FANC protein to 20% or less of the amount in control cells has been shown to be sufficient to induce cell death. For example, cells can express up to 5%, up to 10%, up to 15%, or up to 20% of the active FANC polypeptide expressed by control cells.
[0063] In some embodiments, nucleic acid suppression can be used to reduce expression of active FANC polypeptides. The use of nucleic acid suppression methods, such as antisense suppression and RNAi suppression, to downregulate expression of target genes is well established in the art.
[0064] Cells may be transfected with a suppressor nucleic acid (i.e., a nucleic acid molecule that suppresses expression of a FANC protein), such as an siRNA or shRNA, or a heterologous nucleic acid encoding the suppressor nucleic acid. The suppressor nucleic acid reduces expression of active FANC polypeptide by interfering with transcription and / or translation, thereby reducing the activity of the FANC polypeptide in the cell.
[0065] RNAi involves expressing or introducing into cells an RNA molecule containing a sequence identical to or highly similar to the FANCM coding sequence. The RNA molecule interacts with mRNA transcribed from the FANCM gene, resulting in sequence-specific degradation of the mRNA or specific post-transcriptional gene silencing (PTGS). This reduces or suppresses the expression of active FANCM polypeptide (Angell & Baulcombe (1997) The EMBO Journal 16, 12:3675-3684; Voinnet & Baulcombe (1997) Nature 389: pg 553).
[0066] The RNA molecule is preferably double-stranded RNA (dsRNA) (Fire A. et al. Nature 391, (1998)). Synthetic siRNA duplexes have been shown to specifically suppress the expression of endogenous and heterologous genes in a wide range of mammalian cell lines (Elbashir SM. et al. Nature, 411, 494-498, (2001)).
[0067] RNA molecules suitable for use in RNAi suppression include short interfering RNAs (siRNAs). siRNAs are double-stranded RNA molecules 15 to 40 nucleotides in length, preferably 15 to 28 nucleotides or 19 to 25 nucleotides in length, e.g., 19, 20, 21, 22, 23, 24, or 25 nucleotides in length. For example, two unmodified 21-mer oligonucleotides may be annealed together to form siRNA. The siRNA molecule may include a 3' overhang and / or a 5' overhang on each strand, each having a length of about 0, 1, 2, 3, 4, or 5 nucleotides. The lengths of the overhangs on these strands are independent; i.e., the length of the overhang on one strand is independent of the length of the overhang on the second strand.
[0068] Other RNA molecules suitable for use in RNAi include small hairpin RNAs (shRNAs). shRNAs are single-stranded RNA molecules that contain or consist of a short (e.g., 19-25 nucleotide) antisense nucleotide sequence, followed by a 5-9 nucleotide loop and a complementary sense nucleotide sequence (e.g., 19-25 nucleotides). Alternatively, the sense sequence may precede the nucleotide loop structure and be followed by the antisense sequence. The nucleotide loop forms a hairpin turn, allowing base pairing between the complementary sense and antisense sequences to form the shRNA.
[0069] A suppressor nucleic acid, e.g., an siRNA or shRNA, can comprise or consist of a sequence identical or substantially identical (i.e., at least 90%, at least 95%, or at least 98% identical) to all or a portion (e.g., 15 to 40 nucleotides) of a reference FANC nucleotide coding sequence, e.g., SEQ ID NO:2, SEQ ID NO:6, or SEQ ID NO:8, or a complementary sequence thereof. Suitable reference sequences encoding FANCM that can be used to design a suppressor nucleic acid have been published and include SEQ ID NO:2. Suitable reference sequences encoding FANCD2 that can be used to design a suppressor nucleic acid have been published and include SEQ ID NO:6. Suitable reference sequences encoding FANCI that can be used to design a suppressor nucleic acid have been published and include SEQ ID NO:8.
[0070] The activity of the FANC protein is suppressed in cancer cells by downregulating the production of active FANCM polypeptide using a suppressor nucleic acid. For example, an siRNA that suppresses the expression of human FANCM may contain 18 to 22 consecutive nucleotides of SEQ ID NO: 2, an siRNA that suppresses the expression of human FANCD2 may contain 18 to 22 consecutive nucleotides of SEQ ID NO: 6, and an siRNA that suppresses the expression of human FANCi may contain 18 to 22 consecutive nucleotides of SEQ ID NO: 8.
[0071] Examples of preferred siRNA molecules for suppressing human FANCM include SEQ ID NO: 3 (siFa) and SEQ ID NO: 4 (siFb). Suitable siRNA molecules are also described in Silva B, et al., Nat Commun. 2019; 10(1):2253. siRNA molecules for suppressing human FANCM are also commercially available (siRNA IDs s33621 and s33619 (ThermoFisher)) and are also described in Lu R, et al., Nat Commun. 2019; 10(1):2252 (a corrected version is published in Nat Commun. 2019 Nov 20; 10(1):5345).
[0072] Suppressor nucleic acids, such as siRNAs and shRNAs, that reduce the expression of FANC proteins can be readily designed using reference FANC coding sequences and software tools widely available in the art and can be produced using conventional techniques. For example, suppressor nucleic acids can be chemically synthesized, recombinantly produced in vitro or intracellularly (Elbashir, SM et al., Nature 411:494-498 (2001); Elbashir, SM, et al., Genes & Development 15:188-200 (2001)), or obtained from commercial sources (e.g., Cruachem (Glasgow, UK), Dharmacon Research (Lafayette, Colo., USA)).
[0073] In some embodiments, two or more suppressor nucleic acids may be used to suppress the expression of the FANC protein. For example, a pool of siRNAs may be used. Suitable siRNAs and pools of siRNAs can be generated using standard techniques.
[0074] Nucleic acid suppression can also be achieved using antisense technology. Antisense oligonucleotides can be designed to hybridize to the complementary sequence of a nucleic acid, pre-mRNA, or mature mRNA, and reduce or completely or substantially completely block its expression by interfering with the production of base excision repair pathway components. In addition to targeting coding sequences, antisense technology can also be used to target gene regulatory sequences, such as regulatory sequences within the 5' flanking sequence, so that antisense oligonucleotides can interfere with expression control sequences. The construction of antisense sequences and their use are known in the art (Peyman and Ulman, Chemical Reviews, 90:543-584, (1990); Crooke, Ann. Rev. Pharmacol. Toxicol. 32:329-376, (1992)).
[0075] Antisense oligonucleotides can be produced in vitro or ex vivo for administration, or antisense RNA can be produced in cancer cells in vivo when desired to downregulate FANC protein.For this reason, double-stranded DNA can be placed under the control of promoter in " reverse orientation", so that the transcription of antisense strand of DNA generates RNA complementary to the normal mRNA transcribed from the sense strand of target gene.In this case, complementary antisense RNA sequence is thought to bind with mRNA to form duplex, and inhibit the translation of endogenous mRNA of target gene into protein.
[0076] It is not necessary to use the entire sequence corresponding to the FANC coding sequence in reverse orientation. For example, any fragment of sufficient length can be used. It is routine for one skilled in the art to screen fragments of various sizes from various portions of the coding sequence or flanking sequence of a gene to optimize the level of antisense inhibition. It may be advantageous to include the initiating methionine ATG codon and perhaps one or more nucleotides upstream of the initiating codon. Suitable fragments may have about 14 to 23 nucleotides, e.g., about 15, 16, or 17 nucleotides.
[0077] In other embodiments, targeted mutagenesis can be used to reduce expression of active FANC polypeptides. The use of targeted mutagenesis methods, such as gene editing, to knock out or eliminate expression of targeted genes is well established in the art (see, e.g., Gaj et al (2013) Trends Biotechnol. 31(7) 397-405).
[0078] One or more mutations, such as insertions, substitutions, or deletions, can be introduced into the FANC gene in cancer cells. Suitable mutations include deletions of all or part of the FANC gene (e.g., one, two, or more exons), frameshift mutations, or nonsense mutations that introduce premature stop codons. In some preferred embodiments, one or more premature stop codons can be introduced into the FANC coding sequence, preferably within the first 400 codons of the coding sequence. For example, a mutation, such as a premature stop codon, can be introduced into the first 400 codons of the FANCM coding sequence to remove the ATPase domain. These mutations can prevent expression of an active FANC polypeptide, for example, by inhibiting transcription or translation of the FANC gene or by causing expression of an inactive polypeptide.
[0079] Targeted mutagenesis for introducing one or more mutations can be carried out by simple method.For example, cancer cell can be transfected with heterologous nucleic acid that encodes targetable nuclease.Targetable nuclease can inactivate the FANC gene that encodes FANC protein in one or more cells of individual, for example, by introducing one or more mutations that prevent the expression of active FANC polypeptide.
[0080] A targetable nuclease can selectively inactivate the FANC gene encoding a FANC protein, such as FANCM, FANCD2, or FANCI, in an individual's cancer cells. The targetable nuclease can be specifically targeted to cancer cells by conventional techniques, including cell-targeting delivery vehicles, such as viral vectors expressing ligands for specific cell types; direct administration of the targetable nuclease to the tumor, for example, by injection; or selective expression of the targetable nuclease from a heterologous nucleic acid in the cancer cells, for example, using a tissue-specific promoter.
[0081] The targetable nuclease may be site-specific (e.g., ZFN or TALEN) or may be expressed using one or more targeting sequences (e.g., CRISPR / Cas) that target the nuclease to the FANCM gene.
[0082] The heterologous nucleic acid encoding the targetable nuclease may comprise an inducible promoter that promotes expression of the targetable nuclease and any targeting sequences in a particular cell type, such as a tumor cell. For example, the inducible promoter can be a promoter-enhancer cassette that preferentially supports expression of the targetable nuclease and any targeting sequences in tumor cells over other types of host cells.
[0083] Suitable targeted nucleases include, for example, site-specific nucleases, such as zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and meganucleases or RNA-guided nucleases, such as clustered regularly interspaced short palindromic repeat (CRISPR) nucleases.
[0084] Zinc finger nucleases (ZFNs) contain one or more Cys2-His2 zinc finger DNA binding domains and a cleavage domain (i.e., nuclease). The DNA binding domain can be modified to recognize and bind to any nucleic acid sequence using conventional techniques (see, for example, Qu et al. (2013) Nucl Ac Res 41(16):7771-7782). The use of ZFNs to introduce mutations into target genes is known in the art (see, for example, Beerli et al. Nat. Biotechnol. 2002; 20:135-141, Maeder et al. Mol. Cell. 2008; 31:294-301, Gupta et al. Nat. Methods. 2012; 9:588-590), and modified ZFNs are commercially available (Sigma-Aldrich (St. Louis, MO)).
[0085] Transcription activator-like effector nuclease (TALEN) comprises a non-specific DNA cleavage nuclease fused to a DNA binding domain, which comprises a series of modular TALE repeats linked to recognize consecutive nucleotide sequences.The use of TALEN targeting nuclease is known in the art (for example, Joung & Sander (2013) Nat Rev Mol Cell Bio 14:49-55, Kim et al. Nat Biotechnol. (2013); 31:251-258, Miller JC, et al. Nat. Biotechnol. (2011) 29:143-148, Reyon D, et al. Nat. Biotechnol. (2012); 30:460-465).
[0086] Meganucleases are endodeoxyribonucleases characterized by large recognition sites (double-stranded DNA sequences of 12 to 40 base pairs), and as a result, this site is generally found only once in any given genome (see, e.g., Silva et al. (2011) Curr Gene Ther 11(1):11-27).
[0087] CRISPR-targeting nucleases (e.g., Cas9) complex with guide RNAs (gRNAs) and cleave genomic DNA in a sequence-specific manner. The guide RNAs, crRNA and tracrRNA, can be used separately or combined into a single RNA to enable site-specific mammalian genome cleavage in the FANCM gene or its regulatory elements. The use of CRISPR / Cas9 systems to introduce insertions or deletions into genes as a method of reducing transcription is known in the art (e.g., Cader et al Nat Immunol 2016 17 (9) 1046-1056, Hwang et al. (2013) Nat. Biotechnol 31:227-229, Xiao et al., (2013) Nucl Acids Res 1-11, Horvath et al., Science (2010) 327:167-170, Jinek M et al. Science (2012) 337:816-821, Cong L et al. Science (2013) 339:819-823, Jinek M et al. (2013) eLife 2:e00471, Mali P et al. (2013) Science 339:823-826, Qi LS et al. (2013) Cell 152:1173-1183, Gilbert LA et al. (2013) Cell 154:442-451, Yang H et al. (2013) Cell 154:1370-1379 and Wang H et al. (2013) Cell 153:910-918).
[0088] In some embodiments, the targetable nuclease is a Cas endonuclease, preferably Cas9, that is expressed in cancer cells in combination with a guide RNA targeting sequence that targets the Cas endonuclease to cleave genomic DNA within the FANC gene, generating an insertion or deletion that prevents expression of an active FANC polypeptide.
[0089] The nucleic acid sequence encoding the suppressor nucleic acid or targetable nuclease, and optionally, the guide RNA, may be included in an expression vector. Suitable vectors can be selected or constructed containing appropriate regulatory sequences, including promoter sequences, terminator fragments, polyadenylation sequences, enhancer sequences, marker genes, and other sequences as needed. Preferably, the vector contains appropriate regulatory sequences for driving expression of the encoding nucleic acid in host cells. Regulatory sequences suitable for driving expression of heterologous nucleic acid coding sequences in various expression systems are known in the art and include constitutive promoters, such as viral promoters such as CMV or SV40. In some preferred embodiments, tissue-specific or inducible promoters, such as light-inducible promoters, can be used to selectively express the suppressor nucleic acid or targetable nuclease, and optionally, the guide RNA, in cancer cells. The vector may also contain sequences such as an origin of replication and a selectable marker that allow its selection, replication, and expression in bacterial hosts, such as E. coli, and / or eukaryotic cells, such as yeast, insect, or mammalian cells. Suitable vectors for use in expressing suppressor nucleic acids or targetable nucleases in mammalian cells include plasmids and viral vectors, such as retroviruses, lentiviruses, adenoviruses, and adeno-associated viruses. Techniques suitable for expressing suppressor nucleic acids or targetable nucleases in mammalian cells are known in the art (see, for example, Molecular Cloning: a Laboratory Manual: 3rd edition, Russell et al., 2001, Cold Spring Harbor Laboratory Press, or Protocols in Molecular Biology, Second Edition, Ausubel et al. eds. John Wiley & Sons, 1992, Recombinant Gene Expression Protocols Ed. R.S. Tuan (Mar. 1997) Humana Press Inc.).
[0090] Another aspect of the present invention relates to the use of a FANC protein, such as FANCM, FANCD2, or FANCI, to screen for compounds that increase cell death or decrease viability of SETD2-deficient cells and are potentially useful in the treatment of SETD2-deficient cancers.
[0091] The screening method can be used to identify a test compound that binds to an isolated FANC protein. A method for screening a compound that reduces the viability or increases cell death of SETD2-deficient cells can include determining the binding of the test compound to a FANC protein, such as FANCM, FANCD2, or FANCI. For example, the test compound can be contacted with a FANC protein to determine the binding of the test compound to the FANC protein. The binding of the test compound to the FANC protein can indicate that the test compound reduces the viability or increases cell death of SETD2-deficient cells.
[0092] Binding of the test compound to the FANC protein can be determined by standard techniques, such as surface plasmon resonance (SPR).
[0093] In some embodiments, the ability of a test compound to inhibit the interaction of a FANC protein, such as FANCM, FANCD2, or FANCI, with a binding partner can be determined. A method for screening for a compound that reduces the viability or increases cell death of SETD2-deficient cells can include determining the effect of a test compound on the binding of a FANC protein with a binding partner. For example, a FANC protein can be contacted with a binding partner in the presence and absence of a test compound. A reduction in the binding of a FANC protein with a binding partner in the presence of the test compound compared to the absence of the test compound can indicate that the test compound reduces the viability or increases cell death of SETD2-deficient cells.
[0094] Binding partners are proteins that naturally bind to FANC proteins in cells, for example, during homologous recombination, meiosis, and DNA repair. FANCM binding partners can include MHF, FAAP24, HCLK2, BTR complex, and individual members of the BTR complex, such as BLM, RMI1, RMI2, and Topo IIIα. FANCD2 binding partners can include DNA, BRCA2, USP1, and FANCI. FANCI binding partners can include DNA and FANCD2.
[0095] The screening method can be used to identify test compounds that inhibit the activity of FANC protein. The method for screening compounds that reduce the viability of SETD2 cells or increase cell death can include determining the effect of the test compound on the activity of FANC protein. For example, the activity of FANC protein, such as FANCM, FANCD2 or FANCI, can be determined in the presence and absence of the test compound. A decrease in the activity of FANC protein in the presence of the test compound compared to the absence of the test compound indicates that the compound reduces the viability of SETD2-deficient cells or increases cell death.
[0096] In some embodiments, the ATP-dependent DNA helicase / translocase activity of FANCM may be determined in the presence of a test compound compared to its absence. A decrease or reduction in ATP-dependent DNA helicase / translocase activity in the presence of a test compound may indicate that the test compound inhibits the activity of the FANCM protein. For example, the test compound may be a FANCM inhibitor. Suitable methods for determining activity, including ATPase and translocase assays, are known in the art. For example, ATP hydrolysis can be measured in the presence of forked DNA, as described in Coulthard R, et al., Structure. 2013; 21(9):1648-1658. A reduction in ATP hydrolysis may indicate that the test compound reduces or impairs FANCM DNA helicase / translocase activity. Translocase activity can be determined using a D-loop dissociation assay, which tests the dissociation of the D-loop catalyzed by FANCM, as described in Gari K, Decaillet C, Delannoy M, Wu L, Constantinou A. Proc Natl Acad Sci U S A. 2008; 105(42):16107-16112. Reduction or elimination of D-loop dissociation in the presence of the test compound indicates that the test compound can reduce or inhibit the translocase activity of FANCM.
[0097] The exact format of any of the screening or assay methods of the present invention can be varied by those skilled in the art using routine skill and knowledge, and those skilled in the art will be well aware of the need to use appropriate control experiments.
[0098] The FANC protein used in the screening method may be an isolated polypeptide comprising a full-length FANC sequence, e.g., a FANCM reference sequence such as SEQ ID NO: 1 as defined herein, a FANCD2 reference sequence such as SEQ ID NO: 5 as defined herein, a FANCI reference sequence such as SEQ ID NO: 7 as defined herein, or a variant or fragment of any of these sequences. Suitable fragments may comprise at least 50, at least 100, or at least 150 consecutive amino acids of the FANC reference sequence. In some embodiments, a FANCM fragment containing ATPase or translocase activity may be used, e.g., a fragment comprising or consisting of the N-terminal DEAH helicase-like domain corresponding to residues 83-591 of SEQ ID NO: 1. Isolated FANC polypeptides can be produced using standard recombinant techniques.
[0099] The test compound may be an isolated molecule or may be contained in a sample, mixture, or extract, such as a biological sample. Compounds that can be screened using the methods described herein may be natural or synthetic chemical compounds used in drug screening programs, and may include, for example, small organic molecules, polypeptides, and nucleic acids, such as aptamers. Extracts of plants, microorganisms, or other organisms containing several characterized or uncharacterized components may also be used.
[0100] Suitable test compounds for screening include compounds that inhibit the ATP-dependent DNA helicase / translocase activity of FANCM. For example, a suitable test compound may be an ATP analog. Suitable test compounds may also be compounds created using rational drug design to obtain test candidate compounds with specific molecular shapes, sizes, and charge characteristics suitable for regulating FANCM activity.
[0101] Combinatorial library technology provides an efficient method for testing a potentially vast number of different compounds for their ability to modulate the activity of FANC proteins. Such libraries and their uses are known in the art, particularly for all kinds of natural products, small molecules, and peptides. The use of peptide libraries may be preferred in certain situations. In some embodiments, libraries of biomolecules, such as aptamer or antibody molecules, may be preferred.
[0102] The amount of test compound that can be added to the assay of the present invention will usually be determined by trial and error depending on the type of compound used. Typically, a putative inhibitor compound can be used at a concentration of about 0.001 nM to 1 mM or more, for example, 0.01 nM to 100 μM, for example, 0.1 μM to 50 μM, for example, about 10 μM. Even compounds with weak effects may be useful lead compounds for further investigation and development.
[0103] Test compounds may include peptides derived from the FANC protein or its binding partners described above. Membrane-permeable peptide fragments of 5 to 40 amino acids, e.g., 6 to 10 amino acids, can be tested for their ability to bind to or inhibit the activity of FANC protein. The regulatory properties of the peptides can be enhanced by adding one of the following groups to the C-terminus: chloromethyl ketone, aldehyde, and boronic acid. These groups are transition-state analogs of serine, cysteine, and threonine proteases. Blocking the N-terminus of the peptide fragment with carbobenzyl can inhibit aminopeptidases and improve stability (Proteolytic Enzymes, 2nd Ed., Edited by R. Beynon and J. Bond, Oxford University Press, 2001).
[0104] Test compounds may include antibodies, antibody fragments and antibody derivatives, as well as non-immunoglobulin binding molecules such as aptamers, trinectins, anticalins, Kunitz domains, transferrin, nurse shark antigen receptor, and sea lamprey leucine-rich repeat proteins.
[0105] In some embodiments, suitable molecules may be directed to the DEAH helicase-like domain corresponding to residues 83-591 of SEQ ID NO:1, or another portion of the FANCM protein.
[0106] Candidate regulatory antibody molecules can be characterized to determine their binding regions, thereby obtaining single-chain antibodies and fragments thereof that inhibit activity or block interaction with a binding partner. Suitable antibodies can be obtained using techniques standard in the art, including, for example, immunizing a mammal with a suitable peptide, such as a fragment of a proinflammatory polypeptide, or isolating specific antibodies from a recombinantly generated library of expressed immunoglobulin variable domains, for example, using lambda or filamentous bacteriophage that display functional immunoglobulin-binding domains on their surface. See, e.g., WO 92 / 01047.
[0107] Aptamers directed against the FANC protein are also putative agents that modulate FANC activity. Aptamers are nucleic acids that specifically bind to target molecules. Typically, aptamers are small nucleic acids ranging from 15 to 50 bases in length that fold into defined secondary and tertiary structures, such as stem-loops or G-quartets. Aptamers are small nucleic acids that bind to target molecules. d is 10 -12 Aptamers can bind very tightly when the kM is less than M. Aptamers can bind to FANC proteins, such as FANCM, FANCI, or FANCD2, with very high specificity. For example, aptamers have been isolated that have binding affinities that differ by more than 10,000 times between a target molecule and another molecule that differs at only one position on the molecule. Aptamers can bind to FANC proteins, such as FANCM, with kM. dis the k with the control polypeptide d The affinity of an aptamer to a target molecule may be at least 10, 100, 1000, 10,000, or 100,000 times lower than the affinity of an aptamer to a target molecule. The generation and use of aptamers is known in the art (see, e.g., Bunka et al Curr Opin Pharmacol 2010 10 (5) 557-562).
[0108] Test compounds identified as inhibiting the activity of a FANC protein, such as FANCM, FANCI, or FANCD2, may be further investigated using one or more secondary screens. Secondary screens may involve testing biological function or activity in vitro and / or in vivo (e.g., in animal models). For example, the ability of a test compound to reduce SETD2 cell viability or increase cell death may be determined. In some embodiments, secondary screens may involve determining the selectivity of a compound for a FANC protein, such as FANCM, by screening against a panel of isolated enzymes or other protein factors.
[0109] The effect of the test compound identified as FANC inhibitor can be determined in vitro on mammalian cells.For example, the effect of the test compound on SETD2-deficient cell line can be determined.Compared with the absence of compound, the increase in cell death in its presence can suggest that the compound shows useful activity in treating SETD2-deficient cancer.
[0110] As described herein, after identifying a FANC inhibitor potentially useful in treating SETD2-deficient cancers, the method can further include modifying the compound to optimize its pharmaceutical properties. Suitable methods of optimization, for example, by structural modeling, are known in the art. Further optimization or modification can then be performed to arrive at one or more final compounds for in vivo or clinical trials.
[0111] Test compounds identified as FANC inhibitors may be isolated and / or purified, or alternatively, synthesized using conventional techniques of recombinant expression or chemical synthesis. They may then be manufactured and / or used in the preparation, i.e., manufacturing or formulating, of compositions such as drugs, pharmaceutical compositions, or medicaments. Thus, the methods described herein may include formulating the test compound with a pharmaceutically acceptable excipient, vehicle, or carrier into a pharmaceutical composition for therapeutic use.
[0112] Although the above-described FANC antagonists, such as FANC inhibitors, degradation inducers, suppressor nucleic acids, targetable nucleases, and nucleic acids encoding suppressor nucleic acids or targetable nucleases, may be administered alone, the FANC antagonists will typically be administered in the form of a pharmaceutical composition that may contain at least one component in addition to the active agent. The FANC antagonists can be mixed with other reagents, such as buffers, carriers, diluents, preservatives, and / or pharmaceutically acceptable excipients, to produce pharmaceutical compositions for use in cancer immunotherapy. Suitable reagents are described in more detail below.
[0113] Aspects of the present invention provide: (i) a pharmaceutical composition comprising a FANC antagonist selected from (a) a FANC inhibitor, (b) a FANC degradation inducer, (c) a FANC suppressor nucleic acid, (d) a FANC targetable nuclease, or (e) a nucleic acid encoding a FANC suppressor nucleic acid or a FANC targetable nuclease, and a pharmaceutically acceptable excipient; and (ii) a method for producing a pharmaceutical composition for use in cancer immunotherapy, e.g., a pharmaceutical composition for treating SETD2-deficient cancer, comprising mixing the FANC antagonist described above with a pharmaceutically acceptable excipient.
[0114] In some embodiments, the FANC antagonist is a FANCM antagonist selected from (a) a FANCM inhibitor, (b) a FANCM degradation inducer, (c) a FANCM suppressor nucleic acid, (d) a FANCM targetable nuclease, (e) a FANCM suppressor nucleic acid or a nucleic acid encoding a FANCM targetable nuclease; (a) a FANCD2 inhibitor, (b) a FANCD2 degradation inducer, (c) a FANCD2 suppressor nucleic acid, (d) a FANCD2 targetable nuclease. a FANCD2 antagonist selected from (a) a FANCI inhibitor, (b) a FANCI degradation inducer, (c) a FANCI suppressor nucleic acid, (d) a FANCI targetable nuclease, (e) a nucleic acid encoding a FANCI suppressor nucleic acid or a FANCI targetable nuclease; or a FANCI antagonist selected from (a) a FANCI inhibitor, (b) a FANCI degradation inducer, (c) a FANCI suppressor nucleic acid, (d) a FANCI targetable nuclease, (e) a nucleic acid encoding a FANCI suppressor nucleic acid or a FANCI targetable nuclease.
[0115] The term "pharmaceutically acceptable," as used herein, refers to compounds, materials, compositions, and / or dosage forms that are, within the scope of sound medical judgment, suitable for use in contact with the tissues of a subject (e.g., a human) without undue toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit / risk ratio. Each carrier, excipient, etc. must also be "acceptable" in the sense of being compatible with the other ingredients of the formulation.
[0116] Pharmaceutical compositions suitable for administration (e.g., by injection) include aqueous and non-aqueous isotonic, pyrogen-free, sterile injectable solutions which may contain antioxidants, buffers, preservatives, stabilizers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient, as well as aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents. Examples of isotonic vehicles suitable for use in such formulations include sodium chloride injection, Ringer's solution, or lactated Ringer's solution. Suitable vehicles can be found in standard pharmaceutical textbooks, e.g., Remington's Pharmaceutical Sciences, 18 thedition, Mack Publishing Company, Easton, Pa., 1990.
[0117] The FANC antagonists described herein, or pharmaceutical compositions comprising the FANC antagonists, can be administered to a subject by any convenient route of administration, including, but not limited to, parenteral administration, such as by injection (including intravenous injection, particularly intravenous bolus injection), whether systemically / peripherally or to the desired site of action. Suitable injection methods are known in the art and commonly used in therapy (see, e.g., Rosenberg et al., New Eng. J. of Med., 319:1676, 1988).
[0118] Reducing the activity or expression of FANC in SETD2-expressing cells does not affect cell death. Thus, systemic administration, e.g., oral administration or injection, of a FANC antagonist described herein can induce a selective cell death effect on SETD2-deficient cancer cells in an individual relative to other non-SETD2-deficient cells in the individual.
[0119] It is understood that appropriate dosages of FANC antagonists and compositions containing FANC antagonists may vary from patient to patient. Determining the optimal dosage generally requires balancing the level of therapeutic benefit against any risk or adverse side effects of the treatments of the present invention. The selected dosage level will depend on a variety of factors, including, but not limited to, the activity of the particular cells, the route of administration, the time of administration, the rate of cell loss or inactivation, the duration of treatment, other drugs, compounds, and / or materials used in combination, and the patient's age, sex, weight, condition, general health, and previous medical history. The amount of cells and the route of administration are ultimately at the discretion of the physician, but generally, the dosage will be that amount required to achieve a local concentration at the site of action that achieves the desired effect without causing substantial harm or adverse side effects.
[0120] Typical oral dosages of small molecule inhibitors range from about 0.05 mg to about 1000 mg, preferably about 0.1 mg to about 500 mg, and more preferably about 1.0 mg to about 200 mg, administered in one or more doses, such as one to three doses. The exact dosage will depend on the frequency and mode of administration, the sex, age, weight, and general condition of the subject being treated, the nature and severity of the condition being treated and any complications being treated, and other factors apparent to those skilled in the art. For parenteral routes, such as intravenous, intrathecal, intramuscular, and similar administration, dosages are typically about half of those used for oral administration.
[0121] FANC antagonists described herein, such as (a) FANC inhibitors, (b) FANC degradation inducers, (c) FANC suppressor nucleic acids, (d) FANC targetable nucleases, or (e) nucleic acids encoding FANC suppressor nucleic acids or FANC targetable nucleases, can be useful in therapy. For example, a FANC antagonist that reduces the activity of FANC protein can be administered to an individual to treat SETD2-deficient cancers.
[0122] Methods according to some aspects of the invention can include determining binding of an oligonucleotide probe to nucleic acid, e.g., genomic DNA, RNA, or cDNA, obtained from a sample. The probe can comprise a nucleotide sequence that specifically binds to nucleic acid sequences that contain one or more mutations or polymorphisms and does not specifically bind to nucleic acid sequences that do not contain the one or more mutations or polymorphisms, or vice versa.
[0123] The oligonucleotide probe may contain a label, and binding of the probe may be determined by detecting the presence of the label.
[0124] The method may include hybridizing one or more (e.g., two) oligonucleotide probes or primers to the target nucleic acid. If the nucleic acid is double-stranded DNA, hybridization will generally be preceded by denaturation to produce single-stranded DNA. Hybridization may be performed as part of a PCR method or as part of a probing method without PCR. An illustrative approach would be a combination of PCR and low stringency hybridization.
[0125] Binding of a probe to a target nucleic acid (e.g., DNA) can be measured using any of a variety of techniques freely available to those skilled in the art. For example, probes may be radioactively, fluorescently, or enzyme-labeled. Other methods that do not involve labeling the probe include restriction fragment length polymorphism testing, PCR amplification, RNase cleavage, and allele-specific oligonucleotide probing. Probing can also be performed using standard Southern blotting techniques. For example, DNA can be extracted from cells and digested with various restriction enzymes. Restriction fragments can then be separated by agarose gel electrophoresis, followed by denaturation and transfer to a nitrocellulose filter. Labeled probes can be hybridized to the DNA fragments on the filter, and binding can be determined.
[0126] Those skilled in the art can apply appropriate conditions of stringency desired for selective hybridization, taking into account factors such as length and base composition of the oligonucleotide, temperature, and the like.
[0127] Selective hybridization conditions suitable for oligonucleotides of 17 to 30 bases include overnight hybridization in 6xSSC at 42°C, followed by washing in 6xSSC at temperatures gradually increasing from 42°C to 65°C.
[0128] Other suitable conditions and protocols are described in Molecular Cloning: a Laboratory Manual: 3 rd edition, Sambrook & Russell (2001) Cold Spring Harbor Laboratory Press, NY, and Current Protocols in Molecular Biology, Ausubel et al. eds. John Wiley & Sons (1992).
[0129] Cancer is characterized by the abnormal proliferation of malignant cancer cells compared to normal cells, and may include leukemias such as AML, CML, ALL, and CLL, lymphomas such as Hodgkin's lymphoma, non-Hodgkin's lymphoma, and multiple myeloma, as well as solid cancers such as sarcoma, skin cancer, melanoma, bladder cancer, brain cancer, e.g., glioblastoma multiforme, such as pediatric glioblastoma multiforme, breast cancer, uterine cancer, oral cancer, ovarian cancer, prostate cancer, lung cancer, e.g., lung adenocarcinoma and lung squamous cell carcinoma, colorectal cancer, cervical cancer, liver cancer, head and neck cancer, esophageal cancer, pancreatic cancer, renal cancer, e.g., clear cell renal carcinoma, gastric cancer, testicular cancer, gallbladder and biliary tract cancer, thyroid cancer, thymic cancer, bone cancer, and cerebral cancer. Cancers may be familial or sporadic. SET2D-deficient cancers suitable for treatment as described herein may be any of these types of cancer in which SET2D expression or activity is deficient.
[0130] Another aspect of the present invention relates to identifying individuals with cancer who are suitable for treatment with a FANC antagonist described herein, such as (a) a FANC inhibitor, (b) a FANC degradation-inducing agent, (c) a FANC suppressor nucleic acid, (d) a FANC-targetable nuclease, or (e) a nucleic acid encoding a FANC suppressor nucleic acid or a FANC-targetable nuclease. For example, an individual with cancer can be evaluated using the methods described herein to determine whether treatment with a FANC antagonist is likely to benefit the individual, i.e., whether the individual is suitable for treatment according to the first aspect of the present invention. A method for predicting, determining, or assessing the responsiveness of a cancer in an individual to a FANC antagonist that reduces the expression or activity of a FANC protein can include determining the presence of one or more SET2D-deficient cancer cells in a sample of cancer cells from the individual, where the presence of one or more SET2D-deficient cancer cells in the sample indicates that the cancer will be responsive to the FANC antagonist.
[0131] Individuals with cancer who are identified as being responsive to a FANC antagonist can be treated as described herein, for example, using the method of the first aspect of the invention.
[0132] An individual suitable for treatment with a FANC antagonist described herein, such as (a) a FANC inhibitor, (b) a FANC degradation inducer, (c) a FANC suppressor nucleic acid, (d) a FANC targetable nuclease, or (e) a nucleic acid encoding a FANC suppressor nucleic acid or a FANC targetable nuclease, can be a mammal, such as a rodent (e.g., a guinea pig, hamster, rat, mouse), murine (e.g., a mouse), canine (e.g., a dog), feline (e.g., a cat), equine (e.g., a horse), primate, simian (e.g., a monkey or ape), monkey (e.g., a marmoset, baboon), ape (e.g., a gorilla, chimpanzee, orangutan, gibbon), or human.
[0133] In some preferred embodiments, the individual is a human. In other preferred embodiments, a non-human mammal, particularly a mammal traditionally used as a model for demonstrating therapeutic efficacy in humans (e.g., a murine, primate, porcine, canine, or lagomorph) can be used.
[0134] In some embodiments, the individual may have minimal residual disease (MRD) after initial cancer treatment.
[0135] The term "treatment", when used herein in relation to the treatment of a condition, generally relates to treatments and therapies that achieve some desired therapeutic effect, such as inhibiting the progression of the condition, including slowing the rate of progression, halting the rate of progression and ameliorating the condition, and curing the condition.
[0136] Treatment can be any treatment or therapy, whether in humans or animals (e.g., for veterinary use), that achieves some desired therapeutic effect, such as inhibiting or slowing the progression of a condition, including slowing the rate of progression, halting the rate of progression, ameliorating the condition, curing or remission (whether partial or complete) of the condition, preventing, delaying, alleviating or arresting one or more symptoms and / or signs of the condition, or prolonging the survival of a subject or patient beyond that expected in the absence of treatment.
[0137] Treatment as a preventative measure (i.e., prophylaxis) is also included. For example, an individual susceptible to or at risk of developing or recurring cancer can be treated as described herein. Such treatment may prevent or delay the development or recurrence of cancer in the individual.
[0138] In particular, treatment can include inhibiting cancer growth, including complete remission of cancer, and / or inhibiting cancer metastasis. Cancer growth generally refers to any one of a number of indicators that indicate a change in cancer to a more advanced form. Thus, indicators for measuring inhibition of cancer growth include a decrease in cancer cell survival, a decrease in tumor volume or morphology (e.g., determined using computed tomography (CT), ultrasound, or other imaging methods), slowing tumor growth, destruction of tumor vasculature, improved performance in delayed-type skin hypersensitivity tests, increased activity of cytolytic cancer cells, and a decrease in the level of tumor-specific antigens.
[0139] It is shown herein that reducing the expression or activity of FANC protein has a potent and specific effect on SETD2-deficient cancer cells. Thus, in some preferred embodiments, a FANC antagonist described herein, such as (a) a FANC inhibitor, (b) a FANC degradation-inducing agent, (c) a FANC suppressor nucleic acid, (d) a FANC targetable nuclease, or (e) a nucleic acid encoding a FANC suppressor nucleic acid or a FANC targetable nuclease, can be administered to an individual without concomitant other cancer therapies, such as cytotoxic chemotherapy or radiation therapy, i.e., the FANC antagonist can be administered alone.
[0140] In other embodiments, a FANC antagonist described herein, such as (a) a FANC inhibitor, (b) a FANC degradation inducer, (c) a FANC suppressor nucleic acid, (d) a FANC targetable nuclease, or (e) a nucleic acid encoding a FANC suppressor nucleic acid or a FANC targetable nuclease, may be administered in combination with one or more other therapies, such as cytotoxic chemotherapy or radiation therapy. This can be useful, for example, in treating cancers that contain both SETD2-deficient and SETD2-positive cancer cells, or cancers where SETD2 status has not been determined.
[0141] When FANC antagonist is used in combination with additional therapeutic agent, the compounds can be administered sequentially or simultaneously by any convenient route.When FANC antagonist is used in combination with additional therapeutic agent that is active against the same disease, the dosage of each active substance in the combination may be different from that when FANC antagonist is used alone.Appropriate dosage is easily understood by those skilled in the art.
[0142] Administration of the FANC antagonists described herein, such as (a) FANC inhibitors, (b) FANC degradation inducers, (c) FANC suppressor nucleic acids, (d) FANC targetable nucleases, or (e) nucleic acids encoding FANC suppressor nucleic acids or FANC targetable nucleases, can be achieved in a single administration, continuously, or intermittently (e.g., in divided administrations at appropriate intervals) throughout the course of treatment. Methods for determining the most effective means of administration and dosage are known to those skilled in the art and vary depending on the formulation used for therapy, the purpose of therapy, the target cells being treated, and the subject being treated. Single or multiple administrations can be used, with the dosage level and pattern being selected by the treating physician.

[0155] experiment Simultaneous loss of FANCM and SET2D leads to cancer cell death SET domain-containing protein 2 (SETD2) is a histone methyltransferase that is frequently mutated in several types of cancer. We aimed to test the effect of genetic ablation of FANCM on the survival of SETD2-deficient cancer cells.
[0156] Wild-type (WT) and CRISPR / Cas9 SETD2 knockout (KO) clear cell renal cell carcinoma (Caki2) cells were transfected with control (Ctrl) or FANCM siRNA. After 6 days of culture, SETD2-KO Caki2 cells transfected with FANCM-depleting siRNA showed a significant decrease in cell density, suggesting increased cell death in these cells (Figure 1).
[0157] To test whether simultaneous deletion of FANCM and SET2D results in increased cell death, we transfected WT and CRISPR / Cas9 SETD2 knockout (KO) clear cell renal cell carcinoma cells (786-O cell line) with control (Ctrl) or FANCM siRNA. Only 3 days after knockdown, SETD2-KO 786-O cells transfected with siRNA specifically depleting FANCM showed a significant loss of viability, as evidenced by increased PI staining levels detected in flow cytometry experiments (Figure 2). A further increase in specific cell death was observed 6 days after knockdown in SETD2-KO 786-O cells transfected with siRNA specifically depleting FANCM (Figure 3).
[0158] Simultaneous loss of FANCD2 and SET2D leads to cancer cell death To test whether co-deletion of FANCD2 and SET2D leads to increased cell death, we transfected WT (ACHN and Caki-1 cell lines) and SETD2-deficient (RCC-AB, RCC-ER, and RCC-MF cell lines) cells with control (Ctrl) or FANCD2 siRNA. Only 3 days after knockdown, SETD2-mutant RCC-AB, RCC-ER, and RCC-MF cell lines transfected with siRNA specifically depleting FANCD2 showed a significant loss of viability, as evidenced by increased PI staining levels detected by flow cytometry (Figure 4A). A further increase in specific cell death was observed 6 days after knockdown in SETD2-mutant RCC-AB, RCC-ER, and RCC-MF cell lines transfected with siRNA specifically depleting FANCD2 (Figure 4B).
[0159] These results suggest that the simultaneous loss of (i) FANCM or FANCD2 and (ii) SETD2 results in a synthetic lethal phenotype leading to cancer cell death. This synthetic lethal phenotype may be utilized as a monotherapy for cancers with somatic loss of SETD2 or may be administered in addition to chemotherapy and radiation therapy for the treatment of aggressive or recurrent cancers. This also represents a promising approach for the treatment of metastatic cancers, where treatment options are limited.
