Abstract

SCOPE: It was investigated whether apigenin (AP) protected against skeletal muscle atrophy induced by obesity. METHODS AND RESULTS: Mice were fed a high-fat diet (HFD) for 9 weeks to induce obesity, and then were assigned to two groups; the HFD group received a high-fat diet, and the HFD+AP group received a 0.1% AP-containing HFD. After additional feeding of the experimental diet for 8 weeks, mice in the HFD group were highly obese compared with the mice in the standard diet fed mice group. The mice in the AP-treated group showed less fat pad accumulation and less inflammatory cytokines without body weight reduction. The weight of skeletal muscle in the AP group tended to increase as compared with that of the HFD group. Furthermore, AP reduced the expression of atrophic genes, including MuRF1 and Atrogin-1, but increased the exercise capacity. The mitochondrial function and mitochondrial biogenesis were enhanced by AP. In cultured C2C12 cells, AP also suppressed palmitic acid-induced muscle atrophy and mitochondrial dysfunction. In addition, AP activated AMP-activated protein kinase (AMPK) in the C2C12 and the muscle of HFD-induced obese mice. CONCLUSION: The results suggested that AP ameliorated the obesity-induced skeletal muscle atrophy by attenuating mitochondrial dysfunction.

Claims other papers make about this one

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

  • In C2C12 myotubes, apigenin suppresses muscle atrophy and mitochondrial dysfunction induced by palmitic acid.

    “The group also reported that in C2C12 myotubes, apigenin suppresses muscle atrophy and mitochondrial dysfunction induced by palmitic acid [110].”
  • The positive effect of apigenin is related to upregulation of mitochondrial content and downregulation of gene expression of MuRF1 and MAFbx in skeletal muscle of C57BL/6 mice.

    “The positive effect of apigenin is related to the upregulation of mitochondrial content and downregulation of gene expression of MuRF1 and MAFbx in skeletal muscle of C57BL/6 mice [110].”
  • Dietary supplementation of apigenin ameliorates obesity-induced skeletal muscle atrophy and increases exercise capacity.

    “Choi et al. reported that dietary supplementation of apigenin ameliorates the obesity-induced skeletal muscle atrophy and increases the exercise capacity.”

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.
