Scientists Unlock Possible Aging Secret In Genetically Altered Fruit Fly

ScienceDaily (Jan. 23, 2009) — Brown University researchers have identified a cellular mechanism that could someday help fight the aging process.

The finding by Stephen Helfand and Nicola Neretti and others adds another piece to the puzzle that Helfand, a professor of biology, molecular biology, cell biology and biochemistry, first discovered in 2000. Back then, he identified a mutation in the Indy (“I’m Not Dead Yet”) gene that can extend the life span of fruit flies.

Subsequent studies of the Indy flies have led to the new finding that a mechanism in those genetically altered fruit flies appears to reduce significantly the production of free radicals, a cellular byproduct that can contribute to the aging process. This intervention takes place with few or no side effects on the quality of life for the fruit fly. The discovery could lead to the development of new anti-aging treatments.
