  • Patent number: 6821956
    Abstract: The invention provides for the use of oligodeoxynucleotide decoys for the prophylactic or therapeutic treatment of diseases associated with the binding of endogenous transcription factors to genes involved in cell growth, differentiation and signalling or to viral genes. By inhibiting endogenous trans-activating factors from binding transcription regulatory regions, the decoys modulate gene expression and thereby regulating pathological processes including inflammation, intimal hyperplasia, angiogenesis, neoplasia, immune responses and viral infection. The decoys are administered in amounts and under conditions whereby binding of the endogenous transcription factor to the endogenous gene is effectively competitively inhibited without significant host toxicity. The subject compositions comprise the decoy molecules in a context which provides for pharmacokinetics sufficient for effective therapeutic use.

  • Publication number: 20040109843
    Abstract: A pharmaceutical composition is provided for treatment and/or prevention of a disease, a disorder and/or a condition caused by expression of a gene controlled by NF-&kgr;B or ets. The composition comprises at least one decoy and a pharmaceutically acceptable carrier. The decoy is an NF-&kgr;B decoy, an ets decoy, or a chimera decoy of NF-&kgr;B and ets. The disease is cerebral aneurysm, cancer, Marfan's syndrome, aortic detachment, post-angioplasty restenosis, chronic articular rheumatism, asthma, atopic dermatitis, nephritis, renal failure, or plaque rupture. Alternatively, the disease is a disease associated with eosinophilic abnormality (e.g., asthma, vascular diseases, allergic diseases, parasite diseases). The pharmaceutically acceptable carrier may be a hydrophilic polymer, a liposome, or the like.

  • Publication number: 20040087535
    Abstract: The feasibility of gene therapy using NO synthase (NOS) to treat peripheral arterial disease was examined. According to the present invention, transfection of NOS vector resulted in a significant increase in blood flow and capillary density. Thus, the present invention provides a method for treating or preventing angiogenesis-dependent conditions by administering a NOS gene in the form of naked DNA.
