摘要

Dietary interventions are effective ways of extending or shortening lifespan. By examining midlife hepatic gene expressions in mice under different dietary conditions and their correlation with lifespans, we not only identified well-known diet-responsive, lifespan-regulating pathways, such as the mito-chondrial genes, but also predicted some unique or underappreciated ones, such as the peroxisomal biogenesis pathway. We found that lowering the expression of peroxisome proliferation genes decreased cellular peroxide levels and extended the lifespan of fruit flies and worms. These findings show that transcriptional changes resulting from dietary interventions can effectively reflect causal factors in aging and identify longevity pathways.
