-
24. A method of selectively reducing expression of a splice variant of a target comprising contacting said splice variant with a target specific oligonucleotide.
- 25. A method of modulating gene expression of a splice variant encoding a polypeptide in a cell comprising contacting the cell with an oligomeric compound comprising one or more double-stranded regions, said oligomeric compound targeted to a site of an mRNA, said mRNA encoding the polypeptide, wherein said site is unique to the splice variant.
- 55. A method of modulating gene expression of a polypeptide in a cell, said gene producing at least two splice variants, said splice variants comprising at least a first and second splice variant, the method comprising contacting the cell with an oligomeric compound comprising one or more double-stranded regions, said oligomeric compound targeted to a site of the mRNA, said mRNA encoding the polypeptide, wherein the site is unique to the first splice variant.
- 61. A method of modulating the expression of at least one splice variant of a gene, wherein said gene expresses at least a first and second splice variant, the method comprising contacting the cell with an oligomeric compound comprising one or more double-stranded regions, said oligomeric compound targeted to a site of the mRNA, said mRNA encoding the polypeptide, wherein said site is unique to the first splice variant.
- 67. A method of selectively expressing one or more splice variants of a gene, said gene expressing at least a first and a second splice variant, said method comprising contacting a cell with one or more oligomeric compounds, said oligomeric compound comprising one or more double-stranded regions, said oligomeric compound targeted to a site of an mRNA of a first splice variant, wherein said site of the mRNA of the first splice variant is absent in an mRNA of the second splice variant.
-
74. A method of claim D wherein the oligomeric compound has at least one phosphorothioate internucleoside linkage.
- 77. An oligomeric compound comprising one or more double-stranded regions, said oligomeric compound specifically hybridizable with a site in an mRNA of a first splice variant wherein said site is absent in an mRNA of a second splice variant.
- 84. A composition comprising an oligomeric compound comprising one or more double-stranded regions, said oligomeric compound hybridized to an mRNA encoded by a gene, said gene encoding at least a first and a second splice variant, wherein said mRNA comprises a target site of the mRNA of the first splice variant, wherein said target site is absent in the mRNA of the second splice variant.
- 98. A method of selectively expressing a second splice variant of a gene while inhibiting expression of a first splice variant, comprising contacting a cell with one or more oligomeric compounds comprising one or more double-stranded regions, said oligomeric compound targeted to a site on a mRNA of said first splice variant, wherein said site on the mRNA of the first splice variant is absent in the mRNA of the second splice variant, thereby expressing the second splice variant while inhibiting expression of the first splice variant.
- 104. A method of modulating a disease or disorder associated with the expression of a first splice variant of a gene, said gene encoding at least a first and a second splice variant, said method comprising contacting a cell with one or more oligomeric compounds comprising one or more double-stranded regions, said oligomeric compound targeted to a site of an mRNA of the first splice variant, wherein said target site is absent in an mRNA of the second splice variant.
- 113. A method of modulating a disease or disorder associated with the expression of a first splice variant of a gene, said gene encoding at least a first and a second splice variant, said method comprising contacting a cell with one or more oligomeric compounds comprising one or more double-stranded regions, said oligomeric compound targeted to a site of an mRNA of said first splice variant, wherein said target site is absent in the mRNA of the second splice variant.
- 119.
