Evaluating Longevity Genes

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

(From ScienceDaily). Researchers have been hard at work building out a larger set of knowledge of genes and aging in the humble nematode worm: "Worms that lack fully functional daf-2 exhibit significantly extended lives, persisting approximately twice as long as their wild-type counterparts. Daf-2 was first reported as a critical aging-associated gene in 1993, but since that time, scientists have identified dozens of additional genes that are crucial for longevity ... In an effort to perform a comprehensive analysis of gerontology-related genes, the researchers compared gene-expression libraries obtained from daf-2 mutants to those obtained from controls at different ages." Metabolic control and stress response genes appear to be the most affected by daf-2.
