Repeated exercise, or wasting, can change the way key genes work.

Researchers have identified a protein that’s critical to the development of skeletal muscle mass and strength and the tissue’s ability to metabolize glucose. They say their findings may lead to ...

Researchers from Tokyo Metropolitan University have developed a way to treat aging-related muscular atrophy using regenerative medicine. Conventional methods to implant myoblasts, precursors to muscle ...

Muscle atrophy is a prevalent condition in today's societies, but many of the roles that mitochondria play in the process remain unclear. In a recent study, researchers investigated how muscle atrophy ...

The loss of muscle mass, or muscle atrophy, is a relatively common condition in today's aging and increasingly sedentary societies. While the disuse of muscles is the most frequent catalyst for muscle ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have shown that the protein Musashi-2 (Msi2) plays a key role in the regulation of mass and metabolic processes in skeletal muscle. They ...

Two related studies published today in Nature Metabolism show that a specialized intracellular recycling mechanism—chaperone-mediated autophagy (CMA)—is essential for muscle health. Subscribe to our ...

Loss of muscle mass (muscle atrophy) can be a result of aging or lifestyle habits, like being inactive or eating a poor diet. Muscle loss can also point to hormone abnormalities or underlying health ...

A 30-year-old African-American woman presented to the emergency department for medical assessment after becoming too weak to walk. She reported proximal muscle aches in both arms and legs, a skin rash ...
