Developmental Biology: Tiny Brakes For A Growing Heart, Nature
 









Excerpts: The discovery of microRNAs has revolutionized many areas of biology.
The latest news is that these RNAs seem to regulate the crucial balance between
growth and specialization of cardiac cells. (...) How these miRNAs are
restricted to, say, the heart or the brain is not known, nor is it clear what
they are doing there. (...) implicate miRNAs in controlling heart development in
mouse embryos. The work places miRNAs both upstream and downstream of known
cardiac gene-regulation cascades, and provides an exciting basis for
understanding the regulation of organ formation.
