NAD 26-30 clock circadian regulator Homo sapiens 69-74 35616339-9 2022 This is because, NAMPT which is a rate limiting enzyme in NAD+ biosynthesis is transcriptionally regulated by the clock genes and NAD+ in turn is a cofactor regulating the deacetylation activity of sirtuins. NAD 58-62 clock circadian regulator Homo sapiens 114-119 35616339-9 2022 This is because, NAMPT which is a rate limiting enzyme in NAD+ biosynthesis is transcriptionally regulated by the clock genes and NAD+ in turn is a cofactor regulating the deacetylation activity of sirtuins. NAD 130-134 clock circadian regulator Homo sapiens 114-119 35616339-11 2022 Thus, the Clock-NAD+-Sirtuin connection represents a novel "feedback loop" circuit that regulates the metabolic machinery. NAD 16-20 clock circadian regulator Homo sapiens 10-15 35616339-12 2022 The current review underpins the importance of NAD+ on the sirtuin and clock connection in preventing fatty liver disorder. NAD 47-51 clock circadian regulator Homo sapiens 71-76 18662537-4 2008 (2008) now demonstrate that the NAD(+)-dependent enzyme SIRT1 functions as a histone deacetylase that counteracts the activity of CLOCK. NAD 32-38 clock circadian regulator Homo sapiens 130-135 21048160-6 2010 A search for the histone deacetylase (HDAC) that counterbalances CLOCK activity revealed that SIRT1, a nicotinamide adenin dinucleotide (NAD(+))-dependent HDAC, functions in a circadian manner. NAD 137-144 clock circadian regulator Homo sapiens 65-70 19299583-0 2009 Circadian clock feedback cycle through NAMPT-mediated NAD+ biosynthesis. 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 33388853-2 2021 Sirtuins (SIRTs) are nuclear, cytoplasmic and mitochondrial histone deacetylases that influence the circadian clock with clock-controlled oscillatory protein, NAMPT, and its metabolite NAD+. NAD 185-189 clock circadian regulator Homo sapiens 110-115 33388853-4 2021 This review focuses on SIRT1, an NAD+-dependent class III histone deacetylase which counterbalances the intrinsic histone acetyltransferase activity of one of the clock genes, CLOCK. NAD 33-36 clock circadian regulator Homo sapiens 163-168 33388853-4 2021 This review focuses on SIRT1, an NAD+-dependent class III histone deacetylase which counterbalances the intrinsic histone acetyltransferase activity of one of the clock genes, CLOCK. NAD 33-36 clock circadian regulator Homo sapiens 176-181 33038659-5 2020 SIRT1 that is an NAD+-dependent deacetylase positively regulates circadian clock and telomere homeostasis. NAD 17-20 clock circadian regulator Homo sapiens 75-80 22179986-6 2011 A search for the histone deacetylase (HDAC) that counterbalanced CLOCK activity revealed that SIRT1, a nicotinamide adenine dinucleotide (NAD(+))-dependent HDAC, functions in a circadian manner. NAD 103-136 clock circadian regulator Homo sapiens 65-70 22179986-6 2011 A search for the histone deacetylase (HDAC) that counterbalanced CLOCK activity revealed that SIRT1, a nicotinamide adenine dinucleotide (NAD(+))-dependent HDAC, functions in a circadian manner.
