Abstract

Delphinidin, one of the major anthocyanidins, shows protective effects against a variety of pathologies, including cancer, inflammation, and muscle atrophy. The purpose of this study was to determine the preventive mechanism of delphinidin on disuse muscle atrophy. In vitro and in vivo models were used to validate the effects of delphinidin on the expression of MuRF1, miR-23a, and NFATc3. Delphinidin suppressed the upregulation of MuRF1 (1.77 ± 0.05 vs 1.03 ± 0.17, P < 0.05) expression and inhibited the downregulation of miR-23a (0.56 ± 0.05 vs 0.94 ± 0.06, P < 0.05) and NFATc3 (0.61 ± 0.02 vs 1.02 ± 0.08, P < 0.01) expression in dexamethasone-treated C2C12 cells. In gastrocnemius, muscle weight loss was prevented by oral administration of delphinidin. Moreover, delphinidin suppressed MuRF1 (3.35 ± 0.13 vs 2.26 ± 0.3, P < 0.01) expression and promoted miR-23a (0.58 ± 0.15 vs 2.25 ± 0.29, P < 0.001) and NFATc3 (0.85 ± 0.17 vs 1.54 ± 0.13, P < 0.001) expressions. Delphinidin intake may prevent disuse muscle atrophy by inducing miR-23a expression and suppressing MuRF1 expression.

  • Oral administration of delphinidin prevents disuse muscle atrophy by inducing miR-23a expression and nuclear factor of activated T cells 3 and suppressing MuRF1 expression in skeletal muscle of C57BL/6J mice.

    “For instance, oral administration of delphinidin prevents disuse muscle atrophy by inducing the miR-23a expression and nuclear factor of activated T cells 3 and suppressing MuRF1 expression in skeletal muscle of C57BL/6J mice [117,118].”

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.
