Gene Silencing in Mammals by Small Interfering RNAs

Nat Rev Genet. 2002 Oct;3(10):737-47. doi: 10.1038/nrg908.

Abstract

Among the 3 billion base pairs of the human genome, there are approximately 30,000-40,000 protein-coding genes, but the function of at least half of them remains unknown. A new tool - short interfering RNAs (siRNAs) - has now been developed for systematically deciphering the functions and interactions of these thousands of genes. siRNAs are an intermediate of RNA interference, the process by which double-stranded RNA silences homologous genes. Although the use of siRNAs to silence genes in vertebrate cells was only reported a year ago, the emerging literature indicates that most vertebrate genes can be studied with this technology.
