Animal studies indicate that nicotinamide phosphoribosyltransferase [Nampt/visfatin/pre-B-cell colony-enhancing factor (PBEF)] contributes to the circadian fine-tuning of metabolic turnover. However, it is unknown whether circulating Nampt concentrations, which are elevated in type 2 diabetes and obesity, display a diurnal rhythm in humans.
