Molecular genetics of life span in C. elegans: how much does it teach us?

Abstract excerpt

Several loci have been identified in the nematode worm Caenorhabditis elegans that, when mutated, can increase life span. Three of these genes, age-1, daf-2 and clk-1, have now been cloned. Mutations in these three genes are highly pleiotropic and affect many aspects of worm development and behaviour, age-1 and daf-2 act in the same genetic pathway and have similar effects on the worm, age-1 encodes a homologue...
