Abstract

Astragalus polysaccharide (APS) is an important bioactive component of Astragalus membranaceus Bunge (Leguminosae) that has been used in traditional Chinese medicine for treating muscle wasting, a serious complication with complex mechanism manifested as myofibers atrophy and satellite cells apoptosis. In this study, the anti-atrophy and anti-apoptotic activity of Astragalus polysaccharide (APS) was characterized in C2C12 skeletal muscle myotubes and myoblasts. APS inhibited dexamethasone-induced atrophy by restoring phosphorylation of Akt, m-TOR, P70s6k, rpS6 and FoxO3A/FoxO1. The targets that protected C2C12 myoblasts from damage by H2O2 were promoting cells proliferation and inhibiting cells apoptosis. The protective mechanisms involved mitochondrial pathway and death receptor pathway. Moreover, Antioxidant effect of APS was also detected in this work. Our findings suggested that APS could be explored as a protective and perhaps as a therapeutic agent in the management of muscle wasting.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Astragalus polysaccharide inhibits dexamethasone-induced muscle atrophy by increasing phosphorylation of Akt, mTOR, P70S6K, rpS6, and FoxO3a in C2C12 myoblasts.

    “For example, Astragalus polysaccharide, an important bioactive component of Astragalus membranaceus Bunge (Leguminosae), inhibits dexamethasone-induced muscle atrophy by increasing phosphorylation of Akt, mTOR, P70S6K, and rpS6, and FoxO3a in C2C12 myoblasts.”
  • Astragalus polysaccharides promote cell proliferation and inhibit cell apoptosis in H2O2-induced cell damage in C2C12 cells.

    “Besides, Astragalus polysaccharides also promote cell proliferation and inhibit cell apoptosis in H2O2-induced cell damage in C2C12 cells [126].”

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.
