Bartel Lab

Researchers at Whitehead Institute have uncovered how small changes in the fish Argonaute (Ago) protein, an RNA slicing protein, that happened in its lineage an estimated 300 million years ago greatly diminished the efficiency of RNAi in these animals, while another ancestral feature, in a critical pre-microRNA, was retained that enabled the microRNA to still be produced despite the fish’s impaired Ago protein.

Deep in your DNA, a gene has gone haywire and is driving up the production of a protein that is messing with your body. Wouldn’t it be great to sift through all your 20,000-something genes, find the offender, and swat it like a fly? Fortunately, a new technique eventually could do just that.

2005 is off to a good start for Whitehead Member David Bartel. In January, he and his colleagues published a landmark paper in the journal Cell. A week later he was honored with the National Academy of Science's prestigious Award in Molecular Biology. And in March, Bartel was appointed Investigator for the Howard Hughes Medical Institute (HHMI).
