This study shows that ULK1 and ULK2 regulate skeletal muscle growth by balancing protein synthesis and degradation, with lifelong deficiency causing hypertrophy but reduced muscle quality and function, while short-term deficiency allows hypertrophy without impairment.

This study identifies early aging-related changes in muscle MERC ultrastructure and proteome, which are reversed by exercise, suggesting potential therapeutic targets for sarcopenia.
