Abstract

The inflammatory cytokine tumor necrosis factor α (TNFα), upregulated in the obese condition, promotes protein degradation and is implicated in obesity-related skeletal muscle atrophy and age-related sarcopenia. Quercetin, a flavonoid, elicits antioxidative and anti-inflammatory activities. In this study, we investigated the effect of quercetin on TNFα-induced skeletal muscle atrophy as well as its potential mechanism of action. In this study, we observed that quercetin suppressed expression of TNFα-induced atrophic factors such as MAFbx/atrogin-1 and MuRF1 in myotubes, and it enhanced heme oxygenase-1 (HO-1) protein level accompanied by increased nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) in myotubes. The HO-1 inhibitor ZnPP suppressed the inhibitory actions of quercetin on TNFα-induced atrophic responses and degradation of IκB-α in myotubes. Moreover, quercetin supplementation to high-fat diet-fed obese mice inhibited obesity-induced atrophic responses in skeletal muscle, accompanied by upregulation of HO-1 and inactivation of nuclear factor-kappa B (NF-κB), and the quercetin actions were attenuated in Nrf2-deficient mice. These findings suggest that quercetin protects against TNFα-induced muscle atrophy under obese conditions through Nrf2-mediated HO-1 induction accompanied by inactivation of NF-κB. Quercetin may be used as a dietary supplement to protect against obesity-induced skeletal muscle atrophy.

  • Quercetin suppresses the expression of atrophic factors including MAFbx and MuRF1 induced by TNF-α injection under obese conditions in C57BL/6 mice.

    “Kim et al. reported that quercetin suppresses the expression of atrophic factors including MAFbx and MuRF1 induced by TNF-α injection under obese conditions in C57BL/6 mice.”
  • Quercetin enhances heme oxygenase-1 protein level by the activation of nuclear translocation of Nrf2 and the inhibition of NF-κB in myotubes.

    “Furthermore, quercetin enhances heme oxygenase-1 protein level by the activation of nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and the inhibition of NF-κB in myotubes [111].”

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.
