NAD 54-58 clock circadian regulator Homo sapiens 10-15 19299583-2 2009 Here we report that both the rate-limiting enzyme in mammalian nicotinamide adenine dinucleotide (NAD+) biosynthesis, nicotinamide phosphoribosyltransferase (NAMPT), and levels of NAD+ display circadian oscillations that are regulated by the core clock machinery in mice. NAD 63-96 clock circadian regulator Homo sapiens 247-252 19299583-2 2009 Here we report that both the rate-limiting enzyme in mammalian nicotinamide adenine dinucleotide (NAD+) biosynthesis, nicotinamide phosphoribosyltransferase (NAMPT), and levels of NAD+ display circadian oscillations that are regulated by the core clock machinery in mice. NAD 98-102 clock circadian regulator Homo sapiens 247-252 19299583-4 2009 In turn, the circadian transcription factor CLOCK binds to and up-regulates Nampt, thus completing a feedback loop involving NAMPT/NAD+ and SIRT1/CLOCK:BMAL1. NAD 131-135 clock circadian regulator Homo sapiens 44-49
