Dantrolene and coenzyme Q10 as a suggested combination therapy to statin-induced myopathy in high fat diet rats: A possible interference with ROS/ TGF- β / Smad4 signaling pathway

Toxicol Appl Pharmacol. 2024 Mar 18:116900. doi: 10.1016/j.taap.2024.116900. Online ahead of print.ABSTRACTOne of the major hitches for statins' utilization is the development of myotoxicity. Versatile studies reported that the underlining molecular mechanisms including coenzyme Q10 (CoQ10)/ubiquinone depletion, as well as the disturbance in the cytoplasmic Ca2+ homeostasis. Therefore, we investigated the consequences of supplementing CoQ10 and dantrolene, a cytoplasmic Ca2+ reducing agent, in combination with simvastatin. This adjuvant therapy normalized the simvastatin-mediated elevation in serum ALT, AST, CK-MM, as well as tissue Ca2+ content, in addition to suppressing the simvastatin-mediated oxidative stress in simvastatin-treated rats, while having no effect upon statin-induced antihyperlipidemic effect. Additionally, the combination inhibited the simvastatin-induced TGF-β/ Smad4 pathway activation. Collectively, the current study emphasizes on the potential utilization of dantrolene and CoQ10 as an adjuvant therapy to statins treatment for improve their side effect profile.PMID:38508403 | DOI:10.1016/j.taap.2024.116900
