RNA interference is a process in which translation of some of a cell's messenger RNA (mRNA) sequences is prevented, because of the presence of (and consequent destruction of) matching double-stranded RNA sequences. RNA interference is believed...

RNA interference (RNAi) is a mechanism that inhibits gene expression by causing the degradation of specific RNA molecules or hindering the transcription of specific genes. The targets are often RNA from viruses and transposons (probably a form of innate...

The AIDS virus has to hijack human proteins to do its damage, but scientists until now have known only a few dozen of its targets. On Thursday, Harvard researchers unveiled a surprisingly longer list, an important first step in the hunt for new drugs.HIV is...

American scientists who discovered an enzyme that broke new ground in research on cancer and aging are among potential candidates for the Nobel Prize in medicine, the first of six prestigious awards to be announced by the Nobel committees.Another possible winner of Monday's $1.54 million...

U.S. citizens Mario R. Capecchi and Oliver Smithies and Sir Martin J. Evans of Britain won the 2007 Nobel Prize in medicine on Monday for groundbreaking discoveries that led to a technique for manipulating mouse genes.The widely used process has helped scientists use mice to...

Switzerland-based Roche on Monday licensed rights to gene-silencing technology in a potential $1 billion deal that marks the second recent move by a large drug maker to develop novel disease treatments based on Nobel Prize-winning research.Roche is licensing technology in the emerging field of RNA...
