Doctors commonly prescribe metformin to help people with type 2 diabetes lower their blood sugar levels. The drug increases insulin sensitivity through its effects on glucose metabolism.

Metformin may hold surprising benefits in the fight against age-related illness.


However, although there is clear evidence of metformins effectiveness, scientists do not fully understand how it interacts with cells and tissues at the molecular level.

Using cell cultures and mice, the researchers identified numerous biochemical switches for turning various cell and molecular processes on and off.

The findings shed light not only on metformins mechanism of glucose control, but also on a surprising number of other reactions and pathways.

Large-scale clinical trials of metformin are already under way to test the drugs effectiveness in extending life span and health span that is, the proportion of a persons life span that they spend in good health.

However, the underlying biochemistry has been unclear.

Teams from three research centers worked on the study: the Salk Institute for Biological Studies, the Scripps Research Institute both in La Jolla, CA and Weill Cornell Medical College in New York.

"These results," says Reuben J. Shaw, one of the studys corresponding authors, "provide us with new avenues to explore in order to understand how metformin works as a diabetes drug, along with its health-span-extending effects."

"These are pathways that neither we, nor anyone else, would have imagined," he adds.

Shaw is a professor of molecular and cell biology at the Salk Institute and director of the Salk Cancer Center.

More recently, scientists have found that metformin may be effective in a number of other conditions, including obesity, cancer, metabolic syndrome, polycystic ovary syndrome, and nonalcoholic fatty liver disease.

Other recent research has also suggested that metformin may have anti-aging effects Trusted Source and an ability to protect bone, especially during the early phases of rheumatoid arthriti
