Abstract: Abstract: RNA interference (RNAi) is a conserved cellular phenomenon. It holds great prospects in basic research and therapeutic applications. Remarkably， the new RNAi methodology， in combination with the well established transgene technology， can introduce tissue specific RNAi to patients effectively to cure diseases. This paper mainly summarized the mechnism of RNAi and its preclinical applications. The new usage of RNAi and its prospects of therapeutic application were also introduced.
