As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death.

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 ...

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 ...

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 ...

(CNN) — Many people view aging as an inevitable breakdown. Muscle loss, in particular, can carry a sense of dread: the fear that our bodies will become less capable with each passing year. The good ...

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 ...

Muscle loss (atrophy) due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging. New research published in Advanced Science shows that ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

A UCLA study in mice reveals that aging muscle stem cells accumulate a protein that slows repair but boosts survival. This protein, NDRG1, acts like a brake, preventing cells from activating quickly ...

Muscle atrophy affects millions of people worldwide, striking when least expected during periods of inactivity, illness, or aging. This natural process of muscle tissue breakdown can happen ...

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 ...
