Overview of gene silencing by RNA interference
Abstract
The potential of harnessing RNA interference (RNAi) for sequence-specific gene silencing has generated much excitement and progress in the field. Recent advances in RNAi technology suggest that RNAi-based approaches may soon become an effective therapeutic strategy against a myriad of diseases. This overview provides a brief description of important considerations when designing an RNAi-based method for gene silencing and therapeutic development: (a) mechanistic aspects of RNAi-mediated gene silencing in mammalian cells; (b) structural requirements for potent siRNA duplexes; (c) off-target effects and interferon responses; and (d) effective delivery of RNAi-inducing agents. Promising therapeutic applications of RNAi that are currently in the developmental pipeline are also described.
