    摘要： The present invention relates to a therapeutic reagent for hepatitis C comprising HCV specific short interfering RNA (siRNA) as an effective ingredient. The siRNA of the invention is a double-stranded RNA specific for the nucleotide sequence of HCV which induces viral RNA degradation in mammalian cells and thereby inhibits HCV protein expression and replication. The method of the invention, which includes the step of administrating the synthetic siRNA or a DNA vector encoding the RNA, is thus effective for the treatment of HCV carrier by inhibiting HCV gene expression and replication.

    摘要： A linear double-stranded RNA molecule, which comprises two or more consecutively or convergently linked short interfering RNAs (siRNAs) each reducing the expression of one of different target genes, and a recombinant expression vector comprising double-stranded DNA sequence expressing the linear double-stranded RNA molecule are provided. The linear double-stranded RNA molecule or the recombinant expression vector is useful for a method of reducing expression of target genes in a cell, the method comprising introducing the linear double-stranded RNA molecule or the recombinant expression vector into the cell, whereby the encoded siRNAs target different genes and reduce expression of the target genes. It was also proved that effective gene silencing activity can be induced when each siRNA unit within the linear double-stranded RNA molecule has 18 to 24 nucleotides and, additionally, the gene silencing activity is not affected by inverted orientation of an siRNA.
