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 ...

Muscle-on-chip systems are three-dimensional human muscle cell bundles cultured on collagen scaffolds. A Stanford University research team sent some of these systems to the International Space Station ...

It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold ...

With the intensification of global population aging, muscle atrophy, characterized by the loss of muscle mass and function, has become an important health issue affecting the elderly. Researchers have ...

The “atrofish” reveals early triggers of sarcopenia and links muscle loss to nerve degeneration, establishing a platform for comparative research on muscle aging and potential therapies As people age, ...

Spinal bulbar muscular atrophy (SBMA) causes a loss of motor neurons in the spinal cord and brainstem. It mainly affects facial and swallowing muscles and the muscles in the arms and legs. Previously, ...

GLP-1 drugs have been accused of stealing muscle along with fat, but the evidence suggests the scare may say more about sloppy measurement than about biology. A new study finds that much of the ...

HGF nitration disrupts muscle homeostasis as an organism age. The new rat anti-HGF monoclonal antibody the research team developed, called 1H41C10, specially binds to the nitration sites of HGF and ...
