Abstract

Saponin derived from natural extracts can alleviate muscle atrophy. Dioscorea nipponica Makino (DNM) is commonly used in herbal medicine and contains various steroidal saponins, although its efficacy and mechanisms of action for treating muscle atrophy remain unknown. Here, differentiated myoblast cells treated with DNM showed increased MyoD and MyoG expression and effectively promoted muscle formation. DNM effectively inhibited muscle atrophy induced by tumor necrosis factor alpha (TNFα) monotherapy, and combination treatment with protodioscin and protogracillin (among the tested DNM constituents) showed a synergistic effect on differentiated myoblast cells. DNM and this combination repressed TNFα-induced increased MuRF1 and Atrogin1/MAFbx expression by inhibiting nuclear factor-kappa B (NF-κB) expression. DNM also effectively promoted the recovery of muscle formation in injured mice. Therefore, DNM and its multi-constituents can potentially be used as therapeutic agents for muscle-related diseases and represent prospective food supplements.

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.
