Keeping Cells Fit in Old Age by Rewiring a Key Metabolic Switch

Researchers found a way to keep old cells working well by tweaking one metabolic switch, suggesting aging loss of fitness isn't inevitable.

Researchers found that activating a protein called AMPK can prevent aging-related fitness decline in yeast cells, but only if you also prevent it from shutting down fat production—a dual problem that a specially engineered AMPK …

The association of frailty with age and lifespan in mice differs by strain and sex.

Frailty indices have been assessed in mouse models for more than a decade, but the effect of sex and strain on frailty outcomes remains poorly understood. Here, we collated and harmonized item-level 31-item clinical frailty …

How cells clean up their protein factories as we age

Your cells actively recycle and reorganize their protein-making machinery as you age, and this process appears to be essential for living longer.

Researchers discovered that a cellular recycling process called ER-phagy actively remodels the endoplasmic reticulum (the cell's protein-making factory) as we age—shifting its structure and composition in coordinated ways. Remarkably, this same remodeling process is also …

Can senolytic drugs restore fertility in female mice with fatty liver disease?

Researchers treated female mice with fatty liver disease (MASLD) using senolytic drugs—compounds that eliminate senescent (aged) cells—and found pregnancy rates improved, particularly through reduced aging and inflammation in the ovaries. However, the treatment had limited …

How worm mitochondria adapt to stress and live longer

Mild stress on cellular power plants may trigger protective cleanup systems that extend lifespan, a mechanism conserved across species.

This review examines how C. elegans worms switch their mitochondrial energy-production machinery to survive low-oxygen or toxic conditions, and how mild damage to this system can actually extend lifespan. The findings suggest conserved cellular stress-response …
