The molecular architecture of a protein complex that helps determine the fate of human cells has been imaged for the first time by researchers with the U.S. Department of Energy’s Lawrence Berkeley ...

RNA interference (RNAi) is a eukaryotic gene-regulatory pathway that silences the expression of specific genes in response to homologous double-stranded (ds)RNA. The RNA-induced silencing complex ...

In less than 10 years since its inception, RNA interference (RNAi) has had extraordinary impact on biomedical science. RNAi has been demonstrated to influence numerous biological and disease pathways.

Recent studies are revealing more about how the protein complex called RISC--RNA-induced silencing complex--works. RISC is at the heart of the gene-silencing technique called RNA interference, which ...
