Abstract

Mitochondrial oxidative damage is a basic mechanism of aging, and multiple studies demonstrate that this process is attenuated by calorie restriction (CR). However, the molecular mechanism that underlies the beneficial effect of CR on mitochondrial dysfunction is unclear. Here, we investigated in mice the mechanisms underlying CR-mediated protection against hypoxia in aged kidney, with a special focus on the role of the NAD-dependent deacetylase sirtuin 1 (Sirt1), which is linked to CR-related longevity in model organisms, on mitochondrial autophagy. Adult-onset and long-term CR in mice promoted increased Sirt1 expression in aged kidney and attenuated hypoxia-associated mitochondrial and renal damage by enhancing BCL2/adenovirus E1B 19-kDa interacting protein 3-dependent (Bnip3-dependent) autophagy. Culture of primary renal proximal tubular cells (PTCs) in serum from CR mice promoted Sirt1-mediated forkhead box O3 (Foxo3) deacetylation. This activity was essential for expression of Bnip3 and p27Kip1 and for subsequent autophagy and cell survival of PTCs under hypoxia. Furthermore, the kidneys of aged Sirt1+/- mice were resistant to CR-mediated improvement in the accumulation of damaged mitochondria under hypoxia. These data highlight the role of the Sirt1-Foxo3 axis in cellular adaptation to hypoxia, delineate a molecular mechanism of the CR-mediated antiaging effect, and could potentially direct the design of new therapies for age- and hypoxia-related tissue damage.

  • SIRT3 regulates electron transport chain complex II activity, Mn-SOD activity, and autophagy by deacetylation of FOXO3.

    “SIRT3 has been also involved in the regulation by deacetylation of electron transport chain complex II activity (Kendrick et al., 2011), modulation of the activity of Mn-SOD (Qiu et al., 2010) or regulation of autophagy by deacetylation of FOXO3 (Kume et al., 2010).”

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.
