RNA interference (RNAi) is a gene-silencing technology by which small double-stranded RNAs are used to target the degradation of RNA with complementary sequence. RNAi is found in a wide variety of organisms (Caenorhabditis elegans, insects, plants, microorganisms and animals). With RNAi, we have harnessed the gene function to be explored, revolutionized our ability to perform large-scale genetic screens, and even therapeutic potential. (Korean J Clin Microbiol 2007;10:1-5)
