Protein interplay in muscle tied to life span

Brown University biologists have uncovered a complicated chain of molecular events that leads from insulin to protein degradation in muscles and significantly diminished life span in fruit flies. The new study in PLoS Genetics, which may have broad implications across species, identifies the fly version the mammalian protein activin as the central culprit in the process.
