Longevity gene from naked mole rats may be the next 'fountain of youth'

Vera Gorbunova, the Doris Johns Cherry Professor of biology and medicine at Rochester said, "Our study provides a proof of principle that unique longevity mechanisms that evolved in long-lived mammalian species can be exported to improve the lifespans of other mammals,"

Gorbunova, along with colleagues, report in a study published in Nature that they successfully transferred a gene responsible for making high molecular weight hyaluronic acid (HMW-HA) from a naked mole rat to mice. This led to improved health and an approximate 4.4 percent increase in median lifespan for the mice.

The findings open new possibilities for exploring how HMW-HA could also be used to improve lifespan and reduce inflammation-related diseases in humans.
