Abstract

Since the beginning of the century, the mammalian sirtuin protein family (comprising SIRT1-SIRT7) has received much attention for its regulatory role, mainly in metabolism and ageing. Sirtuins act in different cellular compartments: they deacetylate histones and several transcriptional regulators in the nucleus, but also specific proteins in other cellular compartments, such as in the cytoplasm and in mitochondria. As a consequence, sirtuins regulate fat and glucose metabolism in response to physiological changes in energy levels, thereby acting as crucial regulators of the network that controls energy homeostasis and as such determines healthspan.

  • Sirtuins regulate gene expression by deacetylating histone and non-histone substrates, depending on NAD+.

    “sirtuins can regulate gene expression by deacetylating histone and non-histone substrates, and this activity depends on a cofactor linked to the cellular energy status, NAD+ (nicotinamide adenine dinucleotide) (Houtkooper et al., 2012).”

  • The SIRT family of NAD+-dependent deacylases, comprising seven members that vary in tissue specificity, subcellular localization, enzymatic activity, and targets, mediates metabolic flexibility in animal models.

    “The SIRT family of NAD+-dependent deacylases, comprising seven members that vary in tissue specificity, subcellular localization, enzymatic activity, and targets, mediates metabolic flexibility in animal models (42).”
  • Nicotinamide mononucleotide conversion to NAD+ activates SIRT1 and improves glucose homeostasis in mice.

    “Nicotinamide mononucleotide conversion to NAD+ activates SIRT1 and improves glucose homeostasis in mice (42).”
  • SIRT3 is localized in the mitochondrial matrix and targets many proteins involved in metabolic homeostasis, including OXPHOS subunits.

    “SIRT3, which is localized in the mitochondrial matrix, targets many proteins involved in metabolic homeostasis, including OXPHOS subunits (42).”
  • SIRT1 controls the activity of transcription factors and cofactors such as p53, MEF2, FOXO, and PGC1α, which govern mitochondrial biogenesis and activity and lipid and glucose metabolism.

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.
