Tiny cellular antennae key to fat formation in muscle

Like it or not, as we age, our muscle cells are slowly exchanged, one by one, for fat cells. This process quickens when we injure a muscle, and an extreme form of this process is also seen in muscle-wasting diseases such ...

Researchers find key to muscle regeneration

Saint Louis University researchers report in Molecular Metabolism new findings that the nuclear receptor REV-ERB appears to play a key role in muscle regeneration, suggesting the receptor may be a good target for new drugs ...

Reactivation of embryonic genes leads to muscle aging

Developmental genes and pathways strictly regulate embryogenesis. The process is strongly driven by so-called Hox-genes. Now, researchers from the Leibniz Institute on Aging (FLI) in Jena, Germany, can show that one of these ...

Gene controls regeneration of injured muscle by adult stem cells

A key gene enables the repair of injured muscle throughout life. This is the finding of a study in mice led by researchers at NYU Langone Medical Center and the University of Colorado at Boulder, and published online July ...

Protein found to bolster growth of damaged muscle tissue

Johns Hopkins University biologists have found that a protein that plays a key role in the lives of stem cells can bolster the growth of damaged muscle tissue, a step that could potentially contribute to treatments for muscle ...

Why do aged muscles heal slowly?

As we age, the function and regenerative abilities of skeletal muscles deteriorate, which means it is difficult for the elderly to recover from injury or surgery. New work from Carnegie's Michelle Rozo, Liangji Li, and Chen-Ming ...

Scientist identify first steps in muscle regeneration

Scientists from Monash University's Australian Regenerative Medicine Institute ARMI have found the first real evidence of how muscles may be triggered to regenerate or heal when damaged. The research could open the way to ...
