Sirtuin-1 regulation of mammalian metabolism.
Sirtuin-1 (SirT1) is a nutrient-sensing deacetylase whose levels and activity increase with caloric restriction to preserve euglycemia and promote efficient energy utilization. Focusing on data obtained in vivo, we review how SirT1 orchestrates the adaptive response to fasting by stimulating hepatic gluconeogenesis and fatty acid oxidation, increasing circulating adiponectin levels and limiting...
متن کاملRegulation of autophagy by AMP-activated protein kinase/ sirtuin 1 pathway reduces spinal cord neurons damage
Objective(s): AMP-activated protein kinase/sirtuin 1 (AMPK/SIRT1) signaling pathway has been proved to be involved in the regulation of autophagy in various models. The aim of this study was to evaluate the effect of AMPK/SIRT1 pathway on autophagy after spinal cord injury (SCI). Materials and Methods:The SCI model was established in rats in vivo and the primary spinal cord neurons were subject...
متن کاملRole of sirtuin 1 in the regulation of hepatic gene expression by thyroid hormone.
Sirtuin 1 (SIRT1) is a nuclear deacetylase that modulates lipid metabolism and enhances mitochondrial activity. SIRT1 targets multiple transcription factors and coactivators. Thyroid hormone (T(3)) stimulates the expression of hepatic genes involved in mitochondrial fatty acid oxidation and gluconeogenesis. We reported that T(3) induces genes for carnitine palmitoyltransferase (cpt1a), pyruvate...
متن کاملRegulation of histone H2A.Z expression is mediated by sirtuin 1 in prostate cancer
Histone variants seem to play a major role in gene expression regulation. In prostate cancer, H2A.Z and its acetylated form are implicated in oncogenes' upregulation. SIRT1, which may act either as tumor suppressor or oncogene, reduces H2A.Z levels in cardiomyocytes, via proteasome-mediated degradation, and this mechanism might be impaired in prostate cancer cells due to sirtuin 1 downregulatio...
متن کاملPrioritization of rs187728237 and rs80320514 as miRNA-related Variants of Human AEG-1 Gene
ABSTRACT Background and objectives: 3' untranslated region (3'UTR) single nucleotide polymorphisms (SNPs) represent genetic variations that may potentially affect binding of miRNA to coding genes, potentially leading to complex disorders. We aimed to perform in silico analysis of the potential phenotypic effect of 3'UTR S...
