Abstract

Background Genistein has high estrogenic activity. Previous studies have shown beneficial effects of estrogen or hormone replacement therapy on muscle mass and muscle atrophy.Objective We investigated the preventive effects and underlying mechanisms of genistein on muscle atrophy.Methods In Expt. 1, male Wistar rats were fed a diet containing no genistein [control (CON)] or 0.05% genistein (GEN; wt:wt diet) for 24 d. On day 14, the sciatic nerve in the left hind leg was severed, and the right hind leg was sham-treated. In Expt. 2, male C57BL6J mice were subcutaneously administered a vehicle (Veh group) or the estrogen receptor (ER) antagonist ICI 182,780 (ICI group) via an osmotic pump for 27 d, and each group was subsequently fed CON or GEN diets from day 3 to day 27. Muscle atrophy was induced on day 17 as in Expt. 1. In Expt. 3, male C57BL6J mice were subcutaneously administered vehicle or a selective ER agonist-ER-α [4,4',4'-(4-propyl-[1H]-pyrazole-1,3,5-triyl)trisphenol (PPT)] or ER-β [2,3-bis(4-hydroxyphenyl)-propionitrile (DPN)]-or genistein (GEN-sc-i) via an osmotic pump for 13 d, and muscle atrophy was induced on day 3 as in Expt. 1. The ratio of denervated soleus muscle weight to sham-operated soleus muscle weight (d/s ratio) was used as the index of muscle atrophy.Results Expt. 1: The d/s ratio in the GEN group was 20% higher than that in the CON group (P < 0.05). Expt. 2: The d/s ratio in the Veh-GEN group was 14% higher than that in the Veh-CON group (P < 0.05), although there was no significant difference between ICI-CON and ICI-GEN groups (P = 0.69). Expt. 3: The d/s ratio in the PPT-treated group was 20% greater than that in the Veh group (P < 0.05), but DPN and GEN-sc-i had no effect on the d/s ratio (P ≥ 0.05 compared with vehicle).Conclusion Genistein intake mitigated denervation-induced soleus muscle atrophy. ER-α was related to the preventive effect of genistein on muscle atrophy.

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.
