The present invention relates to chemically-modified RNAi constructs for reducing expression of a target gene. In particular, the invention relates to specific patterns of modified nucleotides to be incorporated into RNAi constructs to improve in vivo stability and efficacy. Also described are pharmaceutical compositions comprising the chemically-modified RNAi constructs and methods of inhibiting target gene expression in vivo by administering the chemically-modified RNAi constructs, for example, to treat or ameliorate various disease conditions. |
