From EurekAlert! - Breaking News:
In an effort to understand the biological function of the microRNA mir1, Drs. Nicholas Sokol and Victor Ambros (Darmouth Medical School) have studied the expression profile, transcriptional regulation and loss-of-function phenotype of Drosophila mir-1 (Dmir-1). Strikingly, their study shows that, in Drosophila embryos, mir-1 expression is not required for mesodermal cell fate decisions or cell proliferation during embryogenesis, but rather, that it appears to act to reinforce and maintain cell identity during times of rapid growth.
