(Submitter supplied) SIRT6 is a member of a highly conserved family of NAD+-dependent deacetylases with various roles in metabolism, stress resistance, and life span. SIRT6- deficient mice develop normally but succumb to a lethal hypoglycemia early in life; however, the mechanism underlying this hypoglycemia remained unclear. Here, we demonstrate that SIRT6 functions as a histone H3K9 deacetylase to control the expres- sion of multiple glycolytic genes. more...

(Submitter supplied) Purpose: The complete understanding of how genetic and epigenetic components control beta cell differentiation and function is key to the discovery of novel therapeutic approaches to prevent beta cell dysfunction and failure in the progression of type 2 diabetes. Our goal was to elucidate the role of histone deacetylase SIRT6 in beta-cell development and homeostasis. Methods: The Sirt6 endocrine progenitor cell conditional knockout (EKO) and beta-cell-specific knockout (BKO) mice were generated using the Cre-loxP system. more...

(Submitter supplied) We established HeLa cell lines stably expressing a short hairpin RNA against SIRT6 (S6 sh2), and then completed genome-wide microarray analysis in shSIRT6 knock-down and control pSR HeLa cells. Prior to RNA extraction, HeLa cells were treated with TNF-alpha (5 ng/ml) for the indicated times. Total RNA was extracted with TRIzol (Invitrogen) and amplified with Ambion MessageAmp RNA Amplification kit. Amplified human Universal Reference RNA (Stratagene) was used as reference RNA for analysis. Construction and array hybridization of human cDNA microarrays were performed as previously described (Perou et al., 2000). Groups of assays that are related as part of a time series.

(Submitter supplied) Microarray analysis on total retinal RNA from 15 day old Sirt6 wild-type (WT) and knock-out (KO) mice. The retina is one of the major energy consuming tissues within the body. In this context, synaptic transmission between light-excited rod photoreceptors and downstream ON-bipolar neurons is a highly demanding energy consuming process. Sirtuin 6 (SIRT6), a NAD-dependent deacylase, plays a key role in regulating glucose metabolism. more...

(Submitter supplied) Tumor cells exhibit aberrant metabolism characterized by high glycolysis even in the presence of oxygen. This metabolic reprogramming, known as the Warburg effect, provides tumor cells with the substrates and redox potential required for the generation of biomass. Here, we show that the mitochondrial NAD-dependent deacetylase SIRT3 is a crucial regulator of the Warburg effect. SIRT3 loss promotes a metabolic profile consistent with high glycolysis required for anabolic processes in vivo and in vitro. more...

(Submitter supplied) Sirtuins (Sirt) are a family of enzymes that modify chromatin and other proteins to affect gene activity. Loss of Sirt6 leads to a progeria-like phenotype in mice, but the target of SIRT6 action has been elusive. Here we show that Sirt6 binds to thousands of gene promoters in a stress-inducible fashion, guided by the stress-responsive transcription factor NF-κB. Chromatin profiling by ChIP-chip analysis of Sirt6 and NF-KB component RelA combined with expression array data of wildtype, Sirt6 knockout and Sirt6 RelA double knockout cells demonstrates that RelA recruits Sirt6 to NF-KB targets in response to TNF-a induction and that many of these targets are important for senescence and aging.

(Submitter supplied) The SIRT6 deacetylase has been implicated in DNA repair, telomere maintenance, glucose and lipid metabolism and, importantly, it has critical roles in the brain ranging from its development to neurodegeneration. Here, we combined transcriptomics and metabolomics approaches to characterize the functions of SIRT6 in mouse brains. Unexpectedly, our analysis reveals that SIRT6 is a central regulator of mitochondrial activity in the brain. more...

(Submitter supplied) Chromatin remodeling proteins are frequently dysregulated in human cancer, yet little is known about how they control tumorigenesis. Here, we uncover an epigenetic program mediated by the NAD+-dependent histone deacetylase Sirtuin 6 (SIRT6) that is critical for suppression of pancreatic ductal adenocarcinoma (PDAC), one of the most lethal malignancies. SIRT6 inactivation accelerates PDAC progression and metastasis via upregulation of Lin28b, a negative regulator of the let-7 microRNA. more...

(Submitter supplied) Expanding the exercise capacity is an emerging strategy to combat metabolic diseases. Skeletal muscle fiber type determination is critical for the exercise performance, but the regulatory basis is largely unknown. Here, we report that Sirt6 has a role in regulating myofiber configuration toward oxidative type and that Sirt6 activator can be an exercise mimetic. To elucidate molecular mechanisms, we performed RNA-sequencing analysis using WT and skeletal muscle-specific Sirt6 KO mice. more...
