Whitehead Institute for Biomedical Research and MIT researchers have discovered that small RNA molecules called microRNAs regulate thousands of human genes– more than one third of the genome’s protein-coding regions.
These findings contribute to the recent interest in potential therapeutic uses of RNA. For example, using a technique known as RNA interference, or RNAi, researchers are shutting off genes by delivering artificial microRNA-like molecules (siRNAs) into cells. RNAi has… read more
