dc.description.abstractMild inhibition of mitochondrial respiration leads to longevity. Disruption of mitochondrial respiratory components extends lifespan in Caenorhabditis elegans, but the effects appear to be complex and the underlying mechanism for lifespan regulation by mitochondrial respiratory genes is still not fully understood. Here, we investigated the role of Y82E9BR. 3, a worm homolog of the ATP synthase subunit C, in modulating longevity in C. elegans. We found that the Y82E9BR. 3 protein is localized in mitochondria and expressed in various tissues throughout development. RNAi knockdown of Y82E9BR. 3 extends lifespan, decreases the accumulation of lipofuscin, and affects various physiological processes, including development delay, reproduction impairment and slow behavior. Further tissuespecific RNAi analysis showed that the intestine is a crucial organ for the longevity effects conferred by Y82E9BR. 3 RNAi. Moreover, we demonstrated that lifespan extension by Y82E9BR. 3 RNAi is associated with reduced mitochondrial function, as well as the suppression of complex I activity in mitochondria. Unexpectedly, Y82E9BR. 3 RNAi knock down did not influence the whole-worm ATP level. Our findings first reveal the crucial role of Y82E9BR. 3 in mitochondrial function and the underlying mechanism of how Y82E9BR. 3 regulates lifespan in C. elegans.-
