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 ...

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 ...

Muscle atrophy is a primary characteristic of both sarcopenia and cachexia, significantly impacting physical function and quality of life. This figure illustrates the multifaceted causes of muscle ...

Spinal muscular atrophy is a genetically inherited disorder that causes muscle weakness. Adults can get spinal muscular atrophy, but it’s rare in adults and progresses slowly. It doesn’t typically ...

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 ...

A new drug-free, minimally invasive intervention targets the root cause of progressive loss of neural function in spinal muscle atrophy (SMA), an inherited neuromuscular disease. An intervention, ...

BioAge Labs has garnered the support of Eli Lilly to run a trial combining a muscle regeneration therapy with the Big Pharma’s tirzepatide for healthier weight loss. While no financial details were ...

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 ...
