Muscle loss from inactivity may leave behind a lasting molecular “memory,” according to new research. Scientists found that while younger muscle appears to adapt and become more resilient after ...

Loss of muscle mass, also called muscle wasting or atrophy, can happen gradually as part of getting older or more suddenly due to underlying medical conditions. Other factors can contribute, like ...

As we age, our muscles atrophy. Earlier this year, researchers found that hepatocyte growth factor (HGF), a protein critical in skeletal muscle development loses its functionality due to nitration as ...

HOUSTON – A newly identified gene, atrogin-1, is involved in muscle loss associated with cancer, diabetes, fasting and kidney disease as well as in the atrophy occurring with disuse, inactivity, and ...

Distal spinal muscular atrophy (DSMA) is a rare genetic disease that causes a loss of muscle movement. It affects muscles further away from the center of the body, such as the hands, feet, and legs.
