Requirement of NAD and SIR2 for Life-Span Extension by Calorie Restriction in Saccharomyces cerevisiae

Lin, Su-Ju, Defossez, Pierre-Antoine, Guarente, Leonard·2000·Science

Abstract

Calorie restriction extends life-span in a wide variety of organisms. Although it has been suggested that calorie restriction may work by reducing the levels of reactive oxygen species produced during respiration, the mechanism by which this regimen slows aging is uncertain. Here, we mimicked calorie restriction in yeast by physiological or genetic means and showed a substantial extension in life-span. This extension was not observed in strains mutant for SIR2 (which encodes the silencing protein Sir2p) or NPT1 (a gene in a pathway in the synthesis of NAD, the oxidized form of nicotinamide adenine dinucleotide). These findings suggest that the increased longevity induced by calorie restriction requires the activation of Sir2p by NAD.

  • SIR2, an NAD+-dependent deacetylase, was among the first genes linked to the response to caloric restriction, initially in yeast.

    “The NAD+-dependent deacetylase SIR2 was one of the earliest genes to be implicated in the response to caloric restriction, initially in a yeast model (81).”

    “Indeed, different situations of energy restriction, including fasting and exercise, increase NAD+ levels and trigger SIRT1/PGC-1α-dependent mitochondrial adaptation (Lin et al, 2000; Houtkooper et al, 2012).”

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.
