Researchers at the Stanford University School of Medicine have reversed the effects of aging on the skin of mice, at least for a short period, by blocking the action of a single critical protein, NF-kappa-B.

After two weeks, the skin of 2-year-old mice had the same genes active as cells in the skin of newborn mice.

The work backs up the theory that aging is the result of… read more

Stanford University School of Medicine researchers and their colleagues have identified two new proteins that make up the telomerase complex–the protein conglomerate that maintains cells’ genetic material–providing potential new targets for cancer treatments.

Studying telomerase has been difficult because it’s available only in small quantities and no technology was sensitive enough to detect it at minute levels.

To get around the quantity problem, the researchers chopped it into… read more

Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine — a future where advanced organ damage can be repaired by the body itself.

In the May 2007 issue of The FASEB Journal, researchers show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process… read more
