    Diminished mitochondrial oxidative phosphorylation and aerobic capacity
    are associated with reduced longevity. We tested whether resveratrol
    (RSV), which is known to extend lifespan, impacts mitochondrial
    function and metabolic homeostasis. Treatment of mice with RSV
    significantly increased their aerobic capacity, as evidenced by their
    increased running time and consumption of oxygen in muscle fibers.
    RSV's effects were associated with an induction of genes for oxidative
    phosphorylation and mitochondrial biogenesis and were largely explained
    by an RSV-mediated decrease in PGC-1α acetylation and an increase
    in PGC-1α activity. This mechanism is consistent with RSV being a
    known activator of the protein deacetylase, SIRT1, and by the lack of
    effect of RSV in SIRT1−/− MEFs. Importantly, RSV treatment
    protected mice against diet-induced-obesity and insulin resistance.
    These pharmacological effects of RSV combined with the association of
    three Sirt1 SNPs and energy homeostasis in Finnish subjects implicates
    SIRT1 as a key regulator of energy and metabolic homeostasis.
