Protein linking exercise to bigger, stronger muscles discovered; Finding might lead to new therapies for muscle-wasting diseases

They suggest that artificially raising the protein's levels might someday help prevent muscle loss caused by cancer, prolonged inactivity in hospital patients, and aging.
