摘要

Avoiding death has been a popular goal throughout the ages, and anti-aging elixirs have never been in short supply. Although the best shot at immortality is still through one's work, there is hope on the scientific horizon that people may be able to live considerably longer than they do now. Over the past 15 years or so, the implementation of molecular genetic approaches in a number of different laboratory organisms has revolutionized research on aging. By systematically manipulating the genes of worms, flies and yeast cells, investigators have identified dozens of genes that can extend the normal life span of each of these species. And the mammalian counterparts of some of those genes seem to share those same life-extending properties-at least in mice. So, the good news is that life span is a plastic trait and that we have identified a large number of genes that can act to delay the aging process. The bad news is that we know next to nothing of how these genes influence life span.
