Calorie restriction–the SIR2 connection

Open access
Guarente, Leonard, Picard, Frédéric·2005·Cell

Abstract

A nutritious diet low in calories improves the health and extends the life span of rodents. Recent studies identified a gene, SIR2, which encodes an NAD-dependent deacetylase and may mediate the effects of calorie restriction. In this review, we discuss SIR2 genes and calorie restriction in the lower organisms yeast and Drosophila. We then describe the physiological changes in mammals during calorie restriction and how they may lead to the observed health benefits. We summarize the roles of mammalian Sirt1 in mediating these changes in tissues and endocrine systems and propose that Sirt1 regulates calorie restriction by sensing low calories and triggering physiological changes linked to health and longevity.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Among 704 70-year-old Swedish men, dietary intakes of vitamin C and α-tocopherol, but not β-carotene, were inversely associated with CRP and IL-6 concentrations measured seven years after dietary information was collected.

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.
