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 ...

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 ...

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 ...

Muscle atrophy is when muscles shrink and weaken due to lack of use. Other symptoms of muscle atrophy include asymmetry and impaired balance. In most cases, muscle atrophy can be reversed with general ...

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 ...

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 ...

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

Muscles are made to move. Stretching and contraction stimulate biochemical pathways within muscle that maintain tissue health. When movement slows—when a broken limb is immobilized in a cast, for ...

A muscle fiber consists of just one cell, but many nuclei. A team has now shown just how varied these nuclei are. The study can help us better understand muscle diseases such as Duchenne muscular ...
