Abstract

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 expression of multiple glycolytic genes. Specifically, SIRT6 appears to function as a corepressor of the transcription factor Hif1alpha, a critical regulator of nutrient stress responses. Consistent with this notion, SIRT6-deficient cells exhibit increased Hif1alpha activity and show increased glucose uptake with upregulation of glycolysis and diminished mitochondrial respiration. Our studies uncover a role for the chromatin factor SIRT6 as a master regulator of glucose homeostasis and may provide the basis for novel therapeutic approaches against metabolic diseases, such as diabetes and obesity.

  • Bioinformatic analysis identified SIRT6 as a third miR-33 predicted target involved in glucose homeostasis.

    “In addition to IRS2 and FRS2, our bioinformatic analysis identified a third miR-33 predicted target involved in glucose homeostasis: the histone deacetylase SIRT6 (25, 26).”
  • SIRT6-deficient mice develop normally but succumb to lethal hypoglycemia early in life, suggesting an important role of SIRT6 in regulating glucose metabolism.

    “SIRT6-deficient mice develop normally but succumb to lethal hypoglycemia early in life, suggesting an important role of SIRT6 in regulating glucose metabolism (25, 26).”
  • SirT6 represses HIF-1α-mediated transcription by binding to chromatin on HREs and attenuating activation of glycolytic genes via deacetylating histones around promoters.

    “In addition, SirT6 has been shown to repress HIF-1α-mediated transcription by binding to chromatin on HREs and attenuating the activation of glycolytic genes via deacetylating histones around the promoters (Zhong et al., 2010).”
  • SIRT6 activation coordinately regulates expression of glycolytic genes, and mice deficient in SIRT6 have severe metabolic defects, signs of accelerated aging, and die prematurely.

    “SIRT6 activation coordinately regulates the expression of glycolytic genes (479), and mice deficient in SIRT6 have severe metabolic defects, signs of accelerated aging, and die prematurely.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
