    摘要: High affinity, chemically modified triplex-forming oligonucleotides (TFOs) and methods for use thereof are disclosed. TFOs are defined as triplex-forming oligonucleotides which bind as third strands to duplex DNA in a sequence specific manner. Triplex-forming oligonucleotides may be comprised of any possible combination of nucleotides and modified nucleotides. Modified nucleotides may contain chemical modifications of the heterocyclic base, sugar moiety or phosphate moiety. A high affinity oligonucleotide (Kd≦2×10−8) which forms a triple strand with a specific DNA segment of a target gene DNA is generated. It is preferable that the Kd for the high affinity oligonucleotide is below 2×10−10. The nucleotide binds or hybridizes to a target sequence within a target gene or target region of a chromosome, forming a triplex region. The binding of the oligonucleotide to the target region stimulates mutations within or adjacent to the target region using cellular DNA synthesis, recombination, and repair mechanisms. The mutation generated activates, inactivates, or alters the activity and function of the target gene.

    摘要: The present invention relates to a method of treatment of Parkinson's disease, and to the use of antisense oligonucleotides or triplex oligonucleotides introduced into targeted brain structures to decrease the function of brain circuits known to be overactive in the Parkinsonian brain. Antisense or triplex oligonucleotides are targeted to the internal globus pallidus and/or substantia nigra pars reticulata (SNr) where the expression of glutamic acid decarboxylase (GAD67, GAD65, or a combination of the two isoforms) is downregulated. The present invention also relates to a method of treatment of Parkinson's disease where antisense or triplex oligonucleotides are targeted to the internal globus pallidus and/or substantia nigra pars reticulata for the downregulation of glutamate receptors. The present invention further relates to a method of treatment of Parkinson's disease where antisense or triplex oligonucleotides are targeted to the thatlamic motor nuclei for the downregulation of GABA receptors.

The dsRNA, upon contact with a cell expressing the bcl-2, inhibits expression of the bcl-2 gene by at least 20%. The invention also relates to a pharmaceutical composition comprising the dsRNA together with a pharmaceutically acceptable carrier. The invention further relates to a vector for inhibiting expression of bcl-2 in a cell, where the vector comprises a regulatory sequence operably linked to a nucleotide sequence that encodes at least one strand of the dsRNA.
