摘要：
The major challenges for anti-hepatitis B Virus (HBV) therapy are the low efficacy of current drugs and the occurrence of drug resistant HBV mutations. A drug with new target sites or independent metabolic pathways may overcome these shortcomings. Small interfering RNA (siRNA) offers the possibility of developing a new anti-HBV therapy. Here we describe the almost complete inhibition of HBV replication by stably expressed 21-mer short hairpin RNAs (shRNA). Besides the conventional targets on HBV reverse-transcriptase, we also systemically targeted other sites of pregenomic RNA, including direct repeat (DR) elements, S, core, and X gene. Our results indicated that shRNAs can serve as efficient alternative anti-HBV agents. They can also be used in combination with chemotherapy, because they showed better effects on the inhibition of HBV replication due to different mechanisms of drug actions. (C) 2003 Elsevier Inc.
