As one approach to clarify this issue, we investigated the effect of aldosterone on in vitro myogenesis and the potential mechanism explaining it.Methods: Myogenesis was induced in mouse C2C12 myoblasts with 2% horse serum. Immunofluorescence, quantitative reversetranscription polymerase chain reaction, Western blot, viability, and migration analyses were performed for experimental research.Results: Recombinant aldosterone treatment suppressed muscle differentiation from mouse C2C12 myoblasts in a dose-dependent manner, and consistently reduced the expression of myogenic differentiation markers. Furthermore, aldosterone significantly increased intracellular reactive oxygen species (ROS) levels in myotubes, and treatment with N-acetyl cysteine, a potent biological thiol antioxidant, reversed the decrease of myotube area, myotube area per myotube, nucleus number per myotube, and fusion index due to aldosterone through decreasing oxidative stress. A binding enzyme-linked immunosorbent assay confirmed that mineralocorticoid receptor (MR) interacted with aldosterone in C2C12 myoblasts, while eplerenone, an MR inhibitor, blocked aldosterone-stimulated intracellular ROS generation during myogenesis and markedly attenuated the suppression of in vitro myogenesis by aldosterone.Conclusion: These findings support the hypothesis that hypersecretion of aldosterone, like PA, directly contributes to muscular deterioration and suggest that antioxidants and\/or MR antagonists could be effective therapeutic options to reduce the risk of sarcopenia in these patients.<\/jats:p>","DOI":"10.3803\/enm.2021.1108","type":"journal-article","created":{"date-parts":[[2021,8,11]],"date-time":"2021-08-11T05:46:27Z","timestamp":1628660787000},"page":"865-874","update-policy":"https:\/\/doi.org\/10.3803\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Aldosterone
