31 results about "Antisense therapy" patented technology

Antisense therapy is a form of treatment for genetic disorders or infections. When the genetic sequence of a particular gene is known to cause a particular disease, it is possible to synthesize a strand of nucleic acid (DNA, RNA or a chemical analogue) that will bind to the messenger RNA (mRNA) produced by that gene and inactivate it, effectively turning that gene "off". This is because mRNA has to be single stranded for it to be translated. Alternatively, the strand might be targeted to bind a splicing site on pre-mRNA and modify the exon content of an mRNA.

TRPM-2 antisense therapy

It has now been determined that antisense therapy which reduces the expression of TRPM-2 provides therapeutic benefits in the treatment of cancer. In particular, such antisense therapy can be applied in treatment of prostate cancer and renal cell cancer. Addition of antisense TRPM-2 ODN to prostatic tumor cells in vivo is effective for delaying the onset of androgen independence. Thus, prostate cancer can be treated in an individual suffering from prostate cancer by initiating androgen-withdrawal to induce apoptotic cell death of prostatic tumor cells in the individual, and administering to the individual a composition effective to inhibit expression of TRPM-2 by the tumor cells, thereby delaying the progression of prostatic tumor cells to an androgen-independent state in an individual Combined use of antisense TRPM-2 and taxanes synergistically enhances cytotoxic chemosensitivity of androgen-independent prostate cancer. In addition, it has also been found that antisense TRPM-2 has beneficial effect for other cancer types. Specifically, antisense TRPM-2 ODN enhances chemosensitivity in human Renal cell cancer, a normally chemoresistant disease with no active chemotherapeutic agent having an objective response rate higher than 10%. Radiation sensitivity is also enhanced when cells expressing TRPM-2 are treated with antisense TRPM-2 ODN. Thus, the antisense TRPM-2 ODNs can be used to enhance hormone sensitivity, chemosensitivity and radiation sensitivity of a variety of cancer types in which expression of TRPM-2 has been observed.

Bridged artificial nucleoside and nucleotide

It is an object of the present invention to provide a novel molecule for antisense therapies which is not susceptible to nuclease degradation in vivo and has a high binding affinity and specificity for the target mRNAs and which can efficiently regulate expression of specific genes. The novel artificial nucleoside of the present invention has an amide bond introduced into a bridge structure of 2′,4′-BNA / LNA. The oligonucleotide containing the 2′,4′-bridged artificial nucleotide has a binding affinity for a single-stranded RNA comparable to known 2′,4′-BNA / LNA and has an increased nuclease resistance over LNA. Particularly, it is expected to be applied to nucleic acid drugs because of its much stronger binding affinity for single-stranded RNAs than S-oligo's affinity

Transport of nucleotides, oligonucleotides and polynucleotides into the cytoplasm and nucleus of cells by peptides

The invention discloses the discovery of naturally occurring peptides that contain fatty acyl and prenyl moieties which permit the transfer of nucleotides, oligonucleotides, and polynucleotides into the cytoplasm and nucleus of cells. Their intrinsic properties cause them to tightly bind to nucleotides. This indicates that they might serve as nucleotide transporters. Experiments demonstrated that they permitted the transfer of nucleotides and polynucleotides into the cytoplasm and nucleus of cells. The peptides, due to their ability to transport ribonucleic acids into cells, can be employed in gene silencing by RNAi (ribonucleic acid interference) and antisense therapy. Among the ailments thought to benefit are: atherosclerosis by regulating cholesterol metabolism, cancer and similar diseases by delivering nucleic acids in chemotherapy. The peptides, due to their ability to transport ribonucleic acids into cells, can be employed in gene silencing.
