Abstract

Summary: Dietary restriction ( DR ) increases lifespan and attenuates age‐related phenotypes in many organisms; however, the effect of DR on longevity of individuals in genetically heterogeneous populations is not well characterized. Here, we describe a large‐scale effort to define molecular mechanisms that underlie genotype‐specific responses to DR . The effect of DR on lifespan was determined for 166 single gene deletion strains in Saccharomyces cerevisiae . Resulting changes in mean lifespan ranged from a reduction of 79% to an increase of 103%. Vacuolar p H homeostasis, superoxide dismutase activity, and mitochondrial proteostasis were found to be strong determinants of the response to DR . Proteomic analysis of cells deficient in prohibitins revealed induction of a mitochondrial unfolded protein response (mt UPR ), which has not previously been described in yeast. Mitochondrial proteotoxic stress in prohibitin mutants was suppressed by DR via reduced cytoplasmic m RNA translation. A similar relationship between prohibitins, the mt UPR , and longevity was also observed in C aenorhabditis elegans . These observations define conserved molecular processes that underlie genotype‐dependent effects of DR that may be important modulators of DR in higher organisms.

  • Even among highly genetically similar strains of yeast or mice, dietary restriction is equally likely to shorten lifespan as to extend lifespan.

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.
