This cluster of papers explores the molecular mechanisms underlying muscle regeneration, satellite cell function, myostatin regulation, ubiquitin ligases, and the role of various signaling pathways such as IGF-1/PI3K/Akt in preventing skeletal muscle atrophy. It also delves into the interaction between inflammatory processes and muscle injury, as well as the involvement of dystrophin in muscle function and disease. The research encompasses a wide range of topics related to muscle biology and potential therapeutic targets for muscle-related disorders.
