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 ...

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.

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 ...

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 ...

Electron microscopy structure of the human RISC-loading complex, with the L-shaped Dicer enzyme shown as a wire map and the Argonaute2 protein, shown in purple. Disclaimer: AAAS and EurekAlert! are ...
