conjunction with the National Institute on Aging, published in December 2013 in CELL, demonstrated that mitochondrial dysfunction (a hallmark of aging) in aging mice is due to a disruption in sirtuin1-dependent nuclear-mitochondrial communication. They further showed that a reduction in NAD+ levels is responsible for this disruption. They also showed this mitochondrial dysfunction was readily reversible by administration of a NAD+ precursor. The authors found that one week of treatment with a c
