How Stress and Longevity Link

Dr. Marc Tatar and colleagues from the University of Minnesota find that a brief genetic response to heat stress can increase a fruit fly’s life span at normal temperatures. The researchers exposed fly strains to short doses of nonlethal warmth, inducing expression of an HSP dubbed HSP70. Flies bred to contain extra copies of HSP70 genes responded to the warmth by producing extra HSP70s, which increased their life span substantially over a two-week period.

Only a brief low level of genetic expression was required to obtain a long-term improvement in survival of the flies.

The finding provides additional evidence that HSPs may be extending human life because our capacity to moderate stress on all organ systems is the mechanism of human aging, Dr. Tatar said.
