Abstract

In two related papers in this issue, Bai et al. (2011a, 2011b) observe that PARP-1- or PARP-2-deficient mice show increased energy expenditure and protection against diet-induced obesity. This metabolic phenotype is achieved, in part, through SIRT1 activation, either by increasing NAD(+) levels or by promoting SIRT1 expression.
