Abstract

Calorie restriction (CR) extends life span in diverse species. Mitochondria play a key role in CR adaptation; however, the molecular details remain elusive. We developed and applied a quantitative mass spectrometry method to probe the liver mitochondrial acetyl-proteome during CR versus control diet in mice that were wild-type or lacked the protein deacetylase SIRT3. Quantification of 3,285 acetylation sites-2,193 from mitochondrial proteins-rendered a comprehensive atlas of the acetyl-proteome and enabled global site-specific, relative acetyl occupancy measurements between all four experimental conditions. Bioinformatic and biochemical analyses provided additional support for the effects of specific acetylation on mitochondrial protein function. Our results (1) reveal widespread reprogramming of mitochondrial protein acetylation in response to CR and SIRT3, (2) identify three biochemically distinct classes of acetylation sites, and (3) provide evidence that SIRT3 is a prominent regulator in CR adaptation by coordinately deacetylating proteins involved in diverse pathways of metabolism and mitochondrial maintenance.

  • During calorie restriction, liver mitochondrial proteins show an overall increase in acetylation, while proteins in other cellular compartments do not.

    “Proteomic characterization of the changes in liver reveals a complicated landscape of alterations, but an overall increase in acetylation levels for mitochondrial proteins but not those found in other cellular compartments during CR (Hebert et al. 2013).”
  • SIRT5 has a major role in controlling lysine succinylation, similar to SIRT3's principal role in mitochondrial lysine acetylation.

    “Our data are consistent with a major role for SIRT5 in regulating Ksucc levels, which is analogous to the principal role of SIRT3 in regulating mitochondrial Lys acetylation (Hebert et al., 2013; Lombard et al., 2007; Smith et al., 2011).”

  • The global increase in protein acetylation does not reflect how specific residues are deacetylated upon caloric restriction.

    “Indeed, the global increase in protein acetylation does not reflect how specific residues are deacetylated upon CR (Hebert et al, 2013).”

  • Recent evidence points toward a role of the mitochondrial sirtuin SIRT3 in the prevention of age-related diseases, possibly through modulation of the mitochondrial acetyl proteome.

    “For instance, recent evidence points toward a role of the mitochondrial sirtuin SIRT3 in the prevention of age-related diseases, possibly through modulation of the mitochondrial acetyl proteome (Hebert 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.
