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.

Okay, are we still doing the LIVEDRUNK jersey second-line nominations?

Mine nomination is

Be selective about what you drink this holiday season.

Bottoms up!
