NAD 44-50 Sirtuin 1 Drosophila melanogaster 82-86 12571358-1 2003 Sir2 is an NAD-dependent histone deacetylase required for transcriptional silencing. NAD 11-14 Sirtuin 1 Drosophila melanogaster 0-4 16626303-1 2006 Resveratrol mimics calorie restriction to extend lifespan of Caenorhabditis elegans, yeast and Drosophila, possibly through activation of Sir2 (silent information regulator 2), a NAD+-dependent histone deacetylase. Resveratrol 0-11 Sirtuin 1 Drosophila melanogaster 138-142 16626303-1 2006 Resveratrol mimics calorie restriction to extend lifespan of Caenorhabditis elegans, yeast and Drosophila, possibly through activation of Sir2 (silent information regulator 2), a NAD+-dependent histone deacetylase. Resveratrol 0-11 Sirtuin 1 Drosophila melanogaster 144-174 12571358-3 2003 First, we performed histone deacetylation assays and found that dSir2 deacetylates a broad range of acetylated lysine residues. Lysine 111-117 Sirtuin 1 Drosophila melanogaster 64-69 12571358-8 2003 With this hyperacetylated histone-DNA complex, we observed potent (50- to 100-fold) NAD-dependent transcriptional repression by purified dSir2. NAD 84-87 Sirtuin 1 Drosophila melanogaster 137-142 12571358-9 2003 In contrast, repression by dSir2 was not observed in parallel experiments in which histones were hyperpropionylated with propionic anhydride. propionic anhydride 121-140 Sirtuin 1 Drosophila melanogaster 27-32 12571358-10 2003 We also found that dSir2 mediates the formation of a nuclease-resistant fast-sedimenting histone-DNA complex in an NAD-dependent manner. NAD 115-118 Sirtuin 1 Drosophila melanogaster 19-24 12535671-2 2003 Recently, it was shown that the Drosophila bHLH repressor proteins, Hairy and Deadpan, bind to and function with the NAD(+)-dependent histone deacetylase, Sir2. NAD 117-123 Sirtuin 1 Drosophila melanogaster 155-159 34893548-11 2022 This retained mitochondrial activity is likely mediated by Sirt1 and PGC1alpha, and is key to cisplatin resistance. Cisplatin 94-103 Sirtuin 1 Drosophila melanogaster 59-64 12524341-6 2002 We found that dSir2 expression is developmentally regulated and that dSir2 has an intrinsic NAD(+)-dependent histone deacetylase activity. NAD 92-98 Sirtuin 1 Drosophila melanogaster 69-74 12086602-1 2002 Yeast SIR2 is a NAD+-dependent histone deacetylase required for heterochromatic silencing at telomeres, rDNA, and mating-type loci. NAD 16-19 Sirtuin 1 Drosophila melanogaster 6-10 11281647-5 2001 Recombinant dHDAC6 and dSIR2 are both insensitive to TSA and HC toxin and resistant, relative to dHDAC1 and dHDAC3, to inhibition by sodium butyrate. trichostatin A 53-56 Sirtuin 1 Drosophila melanogaster 23-28 11281647-5 2001 Recombinant dHDAC6 and dSIR2 are both insensitive to TSA and HC toxin and resistant, relative to dHDAC1 and dHDAC3, to inhibition by sodium butyrate. Butyric Acid 133-148 Sirtuin 1 Drosophila melanogaster 23-28 28252007-0 2017 Alkylresorcinols activate SIRT1 and delay ageing in Drosophila melanogaster. alkylresorcinols 0-16 Sirtuin 1 Drosophila melanogaster 26-31 31624074-8 2019 The results showed that either a HFD or dSir2 knockdown remarkably increased cardiac TG level and d FAS expression, reduced heart fractional shortening and diastolic diameter, increased arrhythmia index, and decreased heart NAD+ level, dSIR2 protein, dSir2 and PGC-1alpha expression levels. NAD 224-227 Sirtuin 1 Drosophila melanogaster 40-45 31624074-9 2019 Contrarily, either exercise or dSir2 overexpression remarkably reduced heart TG level, dFAS expression and arrhythmia index, and notably increased heart fractional shortening, diastolic diameter, NAD+ level, dSIR2 level, and heart dSir2 and PGC-1alpha expression. NAD 196-199 Sirtuin 1 Drosophila melanogaster 31-36 31624074-10 2019 Therefore, we declared that exercise training could improve lipotoxic cardiomyopathy induced by a HFD or cardiac dSir2 knockdown in old Drosophila The NAD+/dSIR2/PGC-1alpha pathway activation was an important molecular mechanism of exercise resistance against lipotoxic cardiomyopathy. NAD 151-154 Sirtuin 1 Drosophila melanogaster 113-118 31624074-10 2019 Therefore, we declared that exercise training could improve lipotoxic cardiomyopathy induced by a HFD or cardiac dSir2 knockdown in old Drosophila The NAD+/dSIR2/PGC-1alpha pathway activation was an important molecular mechanism of exercise resistance against lipotoxic cardiomyopathy. NAD 151-154 Sirtuin 1 Drosophila melanogaster 156-161 31503544-7 2019 Results showed that either cardiac dSir2 overexpression or exercise remarkably increased the cardiac period, systolic interval, diastolic interval, fractional shortening, SOD activity, dSIR2 protein, Foxo, dSir2, Nmnat, and bmm expression levels in the aging flies; they also notably reduced the cardiac triacylglycerol level, malonaldehyde level, and the diastolic dysfunction index. Triglycerides 304-319 Sirtuin 1 Drosophila melanogaster 35-40 31503544-7 2019 Results showed that either cardiac dSir2 overexpression or exercise remarkably increased the cardiac period, systolic interval, diastolic interval, fractional shortening, SOD activity, dSIR2 protein, Foxo, dSir2, Nmnat, and bmm expression levels in the aging flies; they also notably reduced the cardiac triacylglycerol level, malonaldehyde level, and the diastolic dysfunction index. Malondialdehyde 327-340 Sirtuin 1 Drosophila melanogaster 35-40 28252007-2 2017 The natural polyphenolic compound resveratrol received renewed interest when recent findings implicated resveratrol as a potent SIRT1 activator capable of mimicking the effects of calorie restriction. Resveratrol 104-115 Sirtuin 1 Drosophila melanogaster 128-133 28252007-4 2017 It was demonstrated that the SIRT1 activation of resveratrol is affected by the amino acid composition of the substrate. Resveratrol 49-60 Sirtuin 1 Drosophila melanogaster 29-34 34495320-2 2021 Here, we used Drosophila to identify whether cardiac Nmnat/NAD+/SIR2 pathways activation could mediate endurance exercise resistance to lipotoxic cardiomyopathy. NAD 59-63 Sirtuin 1 Drosophila melanogaster 64-68 34495320-6 2021 Therefore, current results confirmed that cardiac Nmnat/NAD+/SIR2 pathways were important antagonists of HFD-induced lipotoxic cardiomyopathy. NAD 56-60 Sirtuin 1 Drosophila melanogaster 61-65 32980539-9 2020 In aged flies, nitrite supplementation significantly downregulated dTOR and upregulated dSir2 gene expression. Nitrites 15-22 Sirtuin 1 Drosophila melanogaster 88-93 28252007-2 2017 The natural polyphenolic compound resveratrol received renewed interest when recent findings implicated resveratrol as a potent SIRT1 activator capable of mimicking the effects of calorie restriction. Resveratrol 34-45 Sirtuin 1 Drosophila melanogaster 128-133 27623778-5 2016 Additionally, the Notch-dependent response of several E(spl) genes is sensitive to metabolic stress caused by 2-deoxy-d-glucose treatment, in a Sirt1-dependent manner. Deoxyglucose 110-127 Sirtuin 1 Drosophila melanogaster 144-149 26538555-7 2016 Furthermore, prunetin-fed males exhibited increased expression of the longevity gene Sirtuin 1 (Sir2) (22%), as well as elevated AMPK activation (51%) and triglyceride levels (29%), whereas glucose levels decreased (36%). prunetin 13-21 Sirtuin 1 Drosophila melanogaster 85-94 27058248-3 2016 Here we show that loss of the Drosophila SIRT1 homolog sir2 leads to the age-progressive onset of hyperglycemia, obesity, glucose intolerance, and insulin resistance. Glucose 122-129 Sirtuin 1 Drosophila melanogaster 41-46 27058248-3 2016 Here we show that loss of the Drosophila SIRT1 homolog sir2 leads to the age-progressive onset of hyperglycemia, obesity, glucose intolerance, and insulin resistance. Glucose 122-129 Sirtuin 1 Drosophila melanogaster 55-59 26538555-7 2016 Furthermore, prunetin-fed males exhibited increased expression of the longevity gene Sirtuin 1 (Sir2) (22%), as well as elevated AMPK activation (51%) and triglyceride levels (29%), whereas glucose levels decreased (36%). prunetin 13-21 Sirtuin 1 Drosophila melanogaster 96-100 24036492-1 2013 Sir2, a member of the sirtuin family of protein acylases, deacetylates lysine residues within many proteins and is associated with lifespan extension in a variety of model organisms. Lysine 71-77 Sirtuin 1 Drosophila melanogaster 0-4 26153625-3 2015 Experiments in vitro showed that cAMP directly bound to SIRT1 and SIRT3 and consequently increased their activity. Cyclic AMP 33-37 Sirtuin 1 Drosophila melanogaster 56-61 24832080-8 2014 Overexpression of SIR2 reduces lifespan variation among different mitochondrial genotypes and further dampens the response of lifespan to CR but not to DR, suggesting that response to these two diets involve different underlying mechanisms. Chromium 138-140 Sirtuin 1 Drosophila melanogaster 18-22 25335240-6 2014 The restitution time after exposure to anoxia was significantly reduced in Group II (on 31% of the control values) Our results suggest that long-term adaptation to low oxygen partial pressure of highly resistant Drosophila significantly reduces the time of restitution and increases the expression of Sir2 and CG14740 genes. Oxygen 168-174 Sirtuin 1 Drosophila melanogaster 301-305 24436303-7 2014 Here, we show that highly selective pharmacological inhibition of Drosophila Sir2 and mammalian SirT1 using the novel inhibitor selisistat (selisistat; 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxamide) can suppress HD pathology caused by mutant huntingtin exon 1 fragments in Drosophila, mammalian cells and mice. 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxamide 128-138 Sirtuin 1 Drosophila melanogaster 77-81 24436303-7 2014 Here, we show that highly selective pharmacological inhibition of Drosophila Sir2 and mammalian SirT1 using the novel inhibitor selisistat (selisistat; 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxamide) can suppress HD pathology caused by mutant huntingtin exon 1 fragments in Drosophila, mammalian cells and mice. 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxamide 140-150 Sirtuin 1 Drosophila melanogaster 77-81 24436303-7 2014 Here, we show that highly selective pharmacological inhibition of Drosophila Sir2 and mammalian SirT1 using the novel inhibitor selisistat (selisistat; 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxamide) can suppress HD pathology caused by mutant huntingtin exon 1 fragments in Drosophila, mammalian cells and mice. 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxamide 152-206 Sirtuin 1 Drosophila melanogaster 77-81 23129806-1 2013 Sir2 is an evolutionarily conserved NAD(+)-dependent deacetylase which has been shown to play a critical role in glucose and fat metabolism. Glucose 113-120 Sirtuin 1 Drosophila melanogaster 0-4 24003736-7 2013 To test the hypothesis that the observed long-term effect of SB exposure on the flies" longevity could be caused by the induction of persistent epigenetic changes, the levels of expression of the longevity-associated genes (hsp70, sir2 and InR) were determined. Butyric Acid 61-63 Sirtuin 1 Drosophila melanogaster 231-235 24003736-8 2013 The expression level of sir2 gene, known to mediate longevity in the fly through a pathway related to calorie restriction, in the group treated at the larval stage with 20 mmol/l SB was significantly higher after the stress (starvation) than in the control group. Butyric Acid 179-181 Sirtuin 1 Drosophila melanogaster 24-28 23325575-8 2013 In addition, THC extended lifespan in Drosophila and inhibited the oxidative stress response by regulating FOXO and Sir2. tetrahydrocurcumin 13-16 Sirtuin 1 Drosophila melanogaster 116-120 23129806-6 2013 By genetic perturbations and metabolic rescue, we provide evidence to illustrate that fat body dSir2 mediates its effects on the muscles via free fatty acids (FFA) and dILPs (from the insulin-producing cells [IPCs]). Fatty Acids, Nonesterified 141-157 Sirtuin 1 Drosophila melanogaster 95-100 22411915-1 2012 Sir2 is an evolutionarily conserved NAD+ dependent protein. NAD 36-40 Sirtuin 1 Drosophila melanogaster 0-4 22610403-7 2012 Moreover, recent Drosophila genetic analyses demonstrate that the neuroprotective molecules Sir2 and FOXO specifically complement mitochondrial dysfunction and DA neuron loss in PINK1 null mutants, suggesting that Sir2 and FOXO protect mitochondria and DA neurons downstream of PINK1. Dopamine 160-162 Sirtuin 1 Drosophila melanogaster 92-96 22610403-7 2012 Moreover, recent Drosophila genetic analyses demonstrate that the neuroprotective molecules Sir2 and FOXO specifically complement mitochondrial dysfunction and DA neuron loss in PINK1 null mutants, suggesting that Sir2 and FOXO protect mitochondria and DA neurons downstream of PINK1. Dopamine 253-255 Sirtuin 1 Drosophila melanogaster 92-96 22610403-7 2012 Moreover, recent Drosophila genetic analyses demonstrate that the neuroprotective molecules Sir2 and FOXO specifically complement mitochondrial dysfunction and DA neuron loss in PINK1 null mutants, suggesting that Sir2 and FOXO protect mitochondria and DA neurons downstream of PINK1. Dopamine 253-255 Sirtuin 1 Drosophila melanogaster 214-218 22411915-2 2012 Although, SIRT1 has been implicated to be a key regulator of fat and glucose metabolism in mammals, the role of Sir2 in regulating organismal physiology, in invertebrates, is unclear. Glucose 69-76 Sirtuin 1 Drosophila melanogaster 10-15 20157536-6 2009 Similarly, increasing dSir2 activity by feeding flies resveratrol, a CR mimetic, increases spontaneous physical activity of flies on high caloric food. Resveratrol 54-65 Sirtuin 1 Drosophila melanogaster 22-27 21596603-2 2011 The NAD(+)-dependent deacetylase and gene repressor SIRT1 removes histone H4K16 acetylation marks and facilitates heterochromatin formation. NAD 4-10 Sirtuin 1 Drosophila melanogaster 52-57 21325893-4 2011 Here we show that a pathway centric approach can be used to identify shared physiological pathways between DR and Sir2, p53 and resveratrol life span extending interventions. Resveratrol 128-139 Sirtuin 1 Drosophila melanogaster 114-118 22156377-8 2011 Based on these results, THC may regulate the aging process via an evolutionarily conserved signaling pathway that includes both foxo and Sir2. tetrahydrocurcumin 24-27 Sirtuin 1 Drosophila melanogaster 137-141 21085633-11 2010 Surprisingly, although Sir2 is typically upregulated under conditions of starvation, Sir2 mutant larvae survive better than wild type under conditions of amino-acid starvation as long as sugars are provided. Sugars 187-193 Sirtuin 1 Drosophila melanogaster 85-89 21085633-12 2010 Our findings point to a Sir2-mediated pathway that activates a catabolic response to amino-acid starvation irrespective of the sugar content of the diet. Sugars 127-132 Sirtuin 1 Drosophila melanogaster 24-28 18762557-4 2008 We also find that among the NAD(+)-dependent class III deacetylases, genetic or pharmacological reduction of either Sir2 or Sirt2 provides neuroprotection to Htt-challenged animals and that even greater neuroprotection is achieved when Rpd3 and Sir2 are simultaneously reduced. NAD 28-32 Sirtuin 1 Drosophila melanogaster 116-120 19851477-0 2009 dSir2 and Dmp53 interact to mediate aspects of CR-dependent lifespan extension in D. melanogaster. Chromium 47-49 Sirtuin 1 Drosophila melanogaster 0-5 19851477-2 2009 In the fruit fly D. melanogaster, CR is mediated at least in part by activation of dSir2. Chromium 34-36 Sirtuin 1 Drosophila melanogaster 83-88 19851477-10 2009 Taken together, our data demonstrate that Dmp53 is a down stream target of dSir2 enzymatic activity and mediates some aspects of the life span extending effects of CR. Chromium 164-166 Sirtuin 1 Drosophila melanogaster 75-80 19049465-0 2008 Highly dissociative and concerted mechanism for the nicotinamide cleavage reaction in Sir2Tm enzyme suggested by ab initio QM/MM molecular dynamics simulations.
