Abstract

Reactive oxygen species (ROS) are a family of compounds that can oxidatively damage cellular macromolecules and may influence lifespan. Sirtuins are a conserved family of nicotinamide adenine dinucleotide (NAD+)-dependent protein deacetylases that regulate lifespan in many model organisms including yeast and mice. Recent work suggests that sirtuins can modulate ROS levels notably during a dietary regimen known as calorie restriction which enhances lifespan for several organisms. Although both sirtuins and ROS have been implicated in the aging process, their precise roles remain unknown. In this review, we summarize current thinking about the oxidative stress theory of aging, discuss some of the compelling data linking the sirtuins to ROS and aging, and propose a conceptual model placing the sirtuins into an ROS-driven mitochondria-mediated hormetic response.

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

  • Oxidized glutathione underpins all mitochondrial H2O2 detoxification and is reduced by NADPH-dependent glutathione reductases.

    “Oxidized glutathione thus underpins all mitochondrial H2O2 detoxification, and is reduced by NADPH-dependent glutathione reductases ((Merksamer et al. 2013)).”
  • Alterations in the affinity of FOXO to DNA and modifications of transcriptional activity play a significant role in the pathology of chronic diseases such as cancer or diabetes and affect the lifespan of organisms by activation of longevity genes such as SIRT6 responsible for the synthesis of antioxidants and HSP chaperones.

    “Alterations in the affinity of FOXO to DNA and modifications of transcriptional activity play a significant role not only in the pathology of chronic diseases such as cancer or diabetes but also affect the lifespan of organisms by activation of longevity genes such as SIRT6 responsible for the synthesis of antioxidants and HSP chaperones (Merksamer et al. 2013).”

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.
