    • The present invention provides double-stranded RNA molecules that mediate RNA interference in target cells, preferably hepatic cells. The invention also provides double-stranded RNA (dsRNA) molecules that are modified to be resistant to nuclease degradation, which inactivates a virus, and more specifically, hepatitis C virus (HCV). The invention also provides a method of using these modified RNA molecules to inactivate virus in mammalian cells and a method of making modified small interfering RNAs (siRNAs) using human Dicer. The invention provides modified RNA molecules that are modified to include a dsRNA or siRNA wherein one or more of the pyrimidines in the RNA molecule are modified to include 2'-Fluorine. The invention also provides dsRNA or siRNA in which all pyrimidines are modified to include a 2'-Fluorine. The invention provides that the 2'-Fluorine dsRNA or siRNA molecule is further modified to include a two base deoxynucleotide "TT" sequence at the 3' end of the molecule.
    • 本发明提供了在靶细胞,优选肝细胞中介导RNA干扰的双链RNA分子。 本发明还提供经修饰以抵抗核酸酶降解的双链RNA(dsRNA)分子,其使病毒失活,并且更具体地使丙型肝炎病毒(HCV)失活。 本发明还提供了使用这些修饰的RNA分子使哺乳动物细胞中的病毒失活的方法以及使用人类切丁酶制备修饰的小干扰RNA(siRNA)的方法。 本发明提供了修饰的RNA分子,其被修饰以包括dsRNA或siRNA,其中RNA分子中的一个或多个嘧啶被修饰以包括2'-氟。 本发明还提供了其中所有嘧啶被修饰为包含2'-氟的dsRNA或siRNA。 本发明提供了将2'-氟dsRNA或siRNA分子进一步修饰以包括双碱基脱氧核苷酸“TT” 序列在分子的3'末端。
