Individual cells of the yeast Saccharomyces cerevisiae have a limited replicative life-span. The role of the genes RAS1 and RAS2 in yeast longevity was examined. Over-expression of RAS2 led to a 30% increase in the life-span on average and postponed the senescence-related increase in generation time seen during yeast aging. No life-span extension was obtained by overexpression of RAS1. However, deletion of RAS1 prolonged the life-span. These results suggest that RAS1 and RAS2 play reciprocal… CONTINUE READING
