Red Wine, Vitamins Don't Really Guarantee Anti Aging
Researchers from McGill University in Canada have identified mutations in 10 different genes of worms (genes believed to have counterparts in humans) that extend their lifespan without reducing the level of oxidative stress the worms suffer.
The results contradict the popular theory that production of toxic reactive oxygen species in tissues is responsible for aging.
"We hope that our study will help in tempering the undue emphasis put on the notion that oxidative stress causes aging and thus that antioxidants could combat aging," said Dr. Siegfried Hekimi, the senior author of the study from the Department of Biology at McGill University in Montreal.
"We also hope that the genes we have discovered can be used in the future to modulate energy metabolism in a way that can help delay the health issues linked to aging, and possibly increase lifespan itself," he added.
To make their discovery, the scientists exposed a passel of worms (Caenorhabditis elegans) to a chemical that causes random changes in its DNA, and looked among the mutagenized worms for those appearing to have a slow rate of metabolism, manifested in their slow development and slow behavioral responses.
