Molecular Fountain of Youth Discovered
Four thousands of years, our thirst for the legendary Fountain of Youth has
been nearly as strong as our propensity for perpetuating the myth.
However, over the last 20 years, the fertile headwaters of molecular biology
have been pumping out anything but folklore. Not only have these waters yielded
a precipitous stretch in understanding the aging process, they’re potentially
guiding us closer to the source of everlasting youth.
From this flow now
comes word that biologists from the University of California, Berkeley have tapped
an influential longevity gene that can NEWS:

The biologists, lead by UC Berkeley assistant professor of nutritional
science and toxicology Danica Chen, focused their attention on one protein in
particular: SIRT3. It’s one in a class of proteins called surtuins, long known
to regulate aging.
Biologists found that SIRT3 plays a significant role in helping aged blood
stem cells cope with the oxidative stress of the aging process. When the blood
stem cells of aged mice were infused with SIRT3, it regenerated new blood
cells, providing evidence of a reversal in the age-related degeneration of the
cells’ function.
“This is really the first demonstration that sirtuins may be able to
actually reverse aging-associated degeneration,” Chen told Discovery News.
“We known aging can be regulated so we may be able to manipulate the
molecular pathways and slow down the process,” she added. “But there’s never
been a demonstration where we could reverse age. It’s really the next big NEWS:

Also of interest is the location of where SIRT3 is found – in the
mitochondria, the cell compartment that helps control growth and death.
“What I liked so much about our study is that SIRT3 is mitochondrial,” said
study co-author Dr. Katharine Brown. “It’s certainly not acting as a
transcription factor, it’s effecting
