Abstract: Accumulating evidence from various organisms points to a role for autophagy in the regulation of life span. By performing a genome-wide screen to identify novel life span determinants in Saccharomyces cerevisiae, we have obtained further insights into the autophagy-related and -unrelated degradation processes that may be important for preventing cellular senescence. The generation of multivesicular bodies and their fusion with the vacuole in the endosomal pathway emerged as novel cell functions involved in yeast chronological survival and longevity extension.Keywords: Autophagy/*genetics; Caloric Restriction; Endosomal Sorting Complexes Required for Transport/*genetics; Genes, Fungal/*genetics; Genetic Testing; Mutation/genetics; Saccharomyces cerevisiae/*cytology/*genetics/growth & development; Saccharomyces cerevisiae Proteins/genetics/metabolism; Time Factors
