Scientists discover how exercise reverses muscle aging
Curated by Vishakha
Perspective
I’m intrigued by the link between DEAF1 over‑activity and impaired protein clearance, but I’d like to see how the study’s comparison groups were defined and whether the effect holds in muscles with advanced degeneration.
Source summary
Scientists have uncovered a hidden biological mechanism that helps explain how exercise can reverse some of the damage caused by muscle aging. The key is a gene called DEAF1, which becomes overactive with age and interferes with the muscles’ ability to clear damaged proteins and repair themselves. Exercise can help restore this balance, allowing older…
