Sir2 mediates longevity in the fly through a pathway related to calorie restriction

Abstract

Calorie restriction can extend life span in a variety of species including mammals, flies, nematodes, and yeast. Despite the importance of this nearly universal effect, little is understood about the molecular mechanisms that mediate the life-span-extending effect of calorie restriction in metazoans. Sir2 is known to be involved in life span determination and calorie restriction in yeast mother cells. In nematodes increased Sir2 can extend life span, but a direct link to calorie restriction has not been demonstrated. We now report that Sir2 is directly involved in the calorie-restriction life-span-extending pathway in Drosophila . We demonstrate that an increase in Drosophila Sir2 (dSir2) extends life span, whereas a decrease in dSir2 blocks the life-span-extending effect of calorie reduction or rpd3 mutations. These data lead us to propose a genetic pathway by which calorie restriction extends life span and provides a framework for genetic and pharmacological studies of life span extension in metazoans.

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?

  • Sirtuins, the Sir2 homologues, mediate certain effects of caloric restriction in flies and mammals.

    “Homologues of Sir2 (called sirtuins) have subsequently been shown to mediate some of the effects of caloric restriction in flies (82) and mammals (83,84).”

  • Overexpression or pharmacologic activation of Sir2 in worms and flies extends life span.

    “Strikingly, overexpression or pharmacologic activation of Sir2 in worms and flies also extends life span (Rogina and Helfand, 2004; Tissenbaum and Guarente, 2001; Wood et al., 2004”

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.
