Since the gene , called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging ,immunity and resistance in humans the scientists said.
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits such as immunity,”said Robin May , who led the study.
Populations across the world are aging at a surprising pace , bring potentially big challenges for health and social care systems . A study by Danish scientists last year found that half of babies born in rich world today will live to celebrate their 100^th birthday . Scientists are eager to find out how people age to try to develop drugs to help them stay healthier lives extend.
“What we have found is that things like resistance and aging tend go hand in hang “ May said in an interview
May’s team compared longevity ,stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAV-16 in each of the four species and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes , which scientists believe play a role in the aging process. “The fact that subtle differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and many explain how differences in lifespan and related traits have arisen during evolution，”May said
