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 ...

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 ...

Changes in motor units closely reflect disease severity in people with spinal muscular atrophy (SMA), suggesting potential ...

Inflammatory myopathies can be challenging to treat, but a new study reports encouraging findings for patients with these debilitating conditions. Researchers from Japan have found that a novel member ...

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 ...

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 ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have developed a way to characterize the force generated by contracting myotubes, precursors to skeletal muscle fiber, combining ...

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 ...
