Researchers isolate gene that reverses aging

Researchers have reversed aging in old mice by injecting them with a longevity gene and rejuvenating their stem cells‘ regenerative potential.

The study by University of California-Berkeley biologists represents a major advance in understanding the molecular mechanisms behind aging, paving the way for the development of targeted treatments for age-related degenerative diseases.

The found that SIRT3, one among a class of proteins known as sirtuins, plays an important role in helping aged blood stem cells cope with stress, the journal Cell reports.

When they infused the blood stem cells of old mice with SIRT3, the treatment boosted the formation of new blood

Stem cell jab ‘may boost muscle’

Muscle wasting linked to old age might one day be treated using stem cells, claim US scientists.

A University of Colorado team transplanted cells into mice and saw the muscle more than double in size – staying that way even into old age.

They say their work, reported in Science Translational Medicine, may have promise in treating muscle-wasting conditions such as muscular dystrophy.
A UK expert said producing a human treatment might be difficult.
Stem cells are cells found in the body which can divide and become a variety of different types of tissue.

Scientists believe they could potentially help treat a large number
