Dana-Farber researchers discover regulator linking exercise to bigger, stronger muscles

  • Posted: December 10, 2012

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. Mice given extra doses of the protein gained muscle mass and strength, and rodents with cancer were much less affected by cachexia, the loss of muscle that often occurs in cancer patients, according to the report in the Dec. 7 issue of the journal Cell.
