RNA silencing A Primer for Researchers
RNA interference (RNAi) is a crucial biological process that plays a vital role in regulating gene expression at the transcriptional and translational levels. It involves the silencing of gene expression through the breakdown of target messenger RNA (mRNA) molecules. This phenomenon is mediated by small, double-stranded RNA molecules known as siRNAs. Investigators have harnessed this natural mechanism for a variety of applications, including gene therapy, drug development, and basic research.
The fundamental steps in RNAi involve the generation of siRNAs from a double-stranded RNA precursor, the assembly of the siRNA to an enzyme complex called RISC (RNA-induced silencing complex), and the directed targeting of mRNA molecules by RISC. This leads to the destruction of target mRNAs, thereby suppressing protein synthesis from those genes.
RNAi has emerged as a versatile tool for studying gene function and its implications in various biological processes.
