The sarcoplasmic reticulum (SR) is a specialised organelle in skeletal muscle fibres that plays a pivotal role in regulating calcium dynamics crucial for muscle contraction and relaxation. Acting as ...

The misconception that muscle can be lean or bulky lies in its appearance. “When people (say ‘lean’), they’re usually ...

A. Fluorescent immunostaining of PDGFRα, showing mesenchymal progenitors, laminin surrounding skeletal muscle, and AR. Arrows indicate mesenchymal progenitors expressing AR, arrowheads indicate ...

Study uncovers a polyphenol's mechanism in enhancing mitochondrial calcium uptake and muscle bioenergetics during aging. Study: Mitochondrial calcium uptake declines during aging and is directly ...

Interestingly, studies in various animal models have shown that time-restricted feeding — a natural non-pharmaceutical intervention — protects against obesity, aging and circadian disruption in ...

A new research paper was published in Volume 17, Issue 11 of Aging-US on November 26, 2025, titled “Epigenetic aging ...

Proteins are essential for body growth and muscle building. However, protein metabolism varies depending on the body’s internal biological clock. Therefore, it is important to know how distribution of ...

Researchers analyzed DNA methylation in human skeletal muscle and identified age-linked epigenetic markers that enable highly ...

GLP-1 receptor agonists have transformed obesity and diabetes care by helping millions shed excess weight—but new mouse research suggests the popular drug may also subtly sap muscle strength, even ...

Infections and neurodegenerative diseases cause inflammation in the brain. But for unknown reasons, patients with brain inflammation often develop muscle problems that seem to be independent of the ...
