Nicotinamide mononucleotide supplementation reverses vascular dysfunction and oxidative stress with aging in mice.

abstract：:Although it is known that the expression and activity of sirtuin 1 (Sirt1) decrease in the aged kidney, the role of interaction between Sirt1 and hypoxia-inducible factor (HIF)-1α is largely unknown. In this study, we investigated whether HIF-1α could be a deacetylation target of Sirt1 and the effect of their interact...
