Mammalian sirtuins—emerging roles in physiology, aging, and calorie restriction

Haigis, Marcia C., Guarente, Leonard P.·2006·Genes & Development

Abstract

Sir2 is an NAD-dependent deacetylase that connects metabolism with longevity in yeast, worms and flies. Mammals contain seven homologs of yeast Sir2, SIRT1–7. Here, we review recent findings demonstrating the role of these mammalian sirtuins as regulators of physiology, calorie restriction, and aging. The current findings sharpen our understanding of sirtuins as potential pharmacological targets to treat the major diseases of aging.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Caloric restriction is the only known intervention that robustly increases lifespan in many species.

    “Caloric restriction — that is, the reduction of calorie intake without causing malnutrition — is the only known intervention that robustly increases lifespan in many species (74).”

    From Neural mechanisms of ageing and cognitive decline (2010) · cites this paper as [74]

  • The histone deacetylase SIR2 has been linked to CR-mediated anti-aging effects in yeast mother cells, flies, and mammals.

    “Moreover, the histone deacetylase SIR2 (the founding member of the sirtuin family) has been linked to CR-mediated anti-aging effects in yeast mother cells, flies, and mammals (Haigis and Guarente, 2006).”

    From The Search for Antiaging Interventions: From Elixirs to Fasting Regimens (2014) · cites this paper as Haigis and Guarente, 2006

  • One common feature of the sirtuins is their enzymatic function as NAD-dependent deacetylases and for yeast Sir2, this biochemical activity is required for the proteins' ability to regulate silencing, recombination and genomic stability.

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.
