Wired on Longevity Drugs

From Wired: "Resveratrol has proven safe in animals and early clinical trials, but much more testing is required. As a cautionary, Longo offered the example of his own research on caloric restriction and genetic manipulation of IGF-1, a cell-growth-regulating gene. In simple organisms, it's produced the most-dramatic life extension ever seen - yeast lived 10 times its normal lifespan - but a group of Ecuadorians who naturally have that mutation have severe growth deficits and other health problems. Even Longo, however, thinks resveratrol will enjoy some success in the near future, and mitochondrial approaches are being steadily embraced within the medical research community, which has been largely frustrated in its disease-by-disease, gene-centered approach. ... The approach we've taken is to go one disease at a time. We've created national institutes to go after all these major diseases, and every time we identify a new gene, or do something that lets us attack disease a little more efficiently than before, everyone jumps up and says we've succeeded and that's wonderful. Such research is important, said Olshansky, but not as promising as hitting diseases at a common root. And though he won't yet commit to resveratrol as a wonder drug, he suspects that mitochondria-targeting drugs will provide a breakthrough."
