Taken together with the finding that resveratrol could only prolong lifespan when fed as part of a high fat diet13,30, this could imply that resveratrol counteracts the negative effects of elevated energy intake.
In summary, this study shows that high doses of coenzyme-Q10 can prevent some motor symptoms, prolong lifespan, and reduce oxidative stress and nerve cell death in HD mice.
3) Scientists prolong lifespan of flies Scientists at the Institute of Cell Biology, in Switzerland, have successfully managed to prolong the lifespan of flies, activating a gene that destroys unhealthy cells.
In C. elegans, signals from the reproductive system can regulate longevity, and ablation of germ cells can alter fat metabolism and significantly prolong lifespan (Hsin and Kenyon, 1999; Goudeau et al., 2011).
The results bode well for the theory that such diets can prolong lifespan in humans, as dieters' hearts worked as well as those of individuals on a calorie-packed western diet who were 15 years younger.
But a recent study published in the journal Cell Metabolism found resveratrol does "prolong lifespan," overturning a 2010 National Institute of Aging report.
However, RNAi knockdown of these genes did not prolong lifespan.
Further, antioxidants have been shown not to prolong lifespan (e.g. [14], [15]).
Likewise for aging, mutations in genes required for chemosensation prolong lifespan [23].
Most mutations that delay aging and prolong lifespan in the mouse are related to somatotropic and/or insulin signaling.
For this reason, it is important to determine whether a marginal level expression can improve life quality and prolong lifespan.
