Abstract
The present invention provides agents, compositions, constructs and methods for silencing HCV polynucleotides, as well as methods and compositions for treating or preventing HCV infection in a mammalian cell. In one aspect, the present invention provides an agent or composition comprising at least one double-stranded RNA effector molecule or complex. The double-stranded RNA effector molecule or complex comprises: (1) a sequence of at least 19 nucleotides having at least 90% identity with a nucleotide sequence within HCV Conserved Region 1 (SEQ ID NO: 2), HCV Conserved Region 2 (SEQ ID NO: 3), HCV Conserved Region 5 (SEQ ID NO: 4), (ATR)-1 (SEQ ID NO: 86), ATR-2 (SEQ ID NO: 87), ATR-3 (SEQ ID NO: 88), ATR-4 (SEQ ID NO: 89); and (2) its complementary sequence. In another aspect, the present invention provides a construct suitable for replication in a host cell, and/or suitable for expression of an RNA molecule or complex of the invention in vitro or in vivo. In a third aspect, the present invention provides a method for silencing HCV RNA in a mammalian cell, which comprises administering to the mammalian cell an agent, composition, or construct of the invention in a manner and amount effective to silence HCV RNA in the cell. In a related aspect, the invention provides a method for treating or preventing HCV infection in a patient, comprising administering to the patient an effective amount of an agent, composition, or construct of the invention as described herein.
