Abstract

Skeletal muscle inflammation and atrophy are closely associated with metabolic impairment such as insulin resistance. Quercetin, a natural polyphenol flavonoid, is known to elicit anti-inflammatory and antioxidant activities. In this study, we investigated its effect on obesity-induced skeletal muscle inflammation and atrophy in mice. Male C57BL/6 mice were fed a regular diet, a high-fat diet (HFD), and an HFD supplemented with quercetin for nine weeks. Quercetin reduced levels of inflammatory cytokines and macrophage accumulation in the skeletal muscle of the HFD-fed obese mice. It also reduced transcript and protein levels of the specific atrophic factors, Atrogin-1 and MuRF1, in the skeletal muscle of the HFD-fed obese mice, and protected against the reduction of muscle mass and muscle fiber size. In vitro, quercetin markedly diminished transcript levels of inflammatory receptors and activation of their signaling molecules (ERK, p38 MAPK, and NF-κB) in cocultured myotubes/macrophages, and this was accompanied by reduced expression of the atrophic factors. Together, these findings suggest that quercetin reduces obesity-induced skeletal muscle atrophy by inhibiting inflammatory receptors and their signaling pathway. Quercetin may be useful for preventing obesity-induced muscle inflammation and sarcopenia.

  • Quercetin could counteract HFD-induced obesity in C57BL/6J mice.

    “It is reported that quercetin could counteract the HFD-induced obesity in C57BL/6J mice [123].”
  • Dietary supplementation with quercetin protects against HFD-induced skeletal muscle inflammation and atrophy in C57BL/6 mice by inhibiting the expression of TNF-α, monocyte chemoattractant protein 1, MAFbx, and MuRF1.

    “Dietary supplementation with quercetin (3,3′,4′,5,7-pentahydroxyflavone), a natural flavonoid mainly present in apples, buckwheat, onions, and citrus fruits, protects against HFD-induced skeletal muscle inflammation and atrophy in C57BL/6 mice by inhibiting the expression of TNF-α, monocyte chemoattractant protein 1, MAFbx, and MuRF1 [123].”

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.
