Protective Role of Ovothiol-A against Muscle and Kidney Injuries in Obese Rats

详细

Background:Obesity is a serious chronic metabolic disease impairing health damaging many organs such as kidneys and muscles. Ovothiol-A (Ovo-A) has been found to keep the redox balance normal in sea urchins indicating its antioxidant characteristics.

Aim:This study aims to investigate the protective effects of Ovo-A on kidneys and muscles in obese rats.

Methods:In-silco studies were performed on lactate dehydrogenase (LDH) and creatine kinase (CK) with Ovo-A to compute their binding affinities. Obesity was induced by high-fat diet (HFD) for 4 weeks. Wistar rats were used in this study as 6 rats per group as control, HFD, Ovo-A (200 and 400 mg/Kg, p.o) groups.

Results:Docking results have revealed that Ovo-A has affinities to bind to LDH (-8.5 kcal/mol) and CK (-17.7 kcal/mol). Ovo-A reduced the levels of uric acid, urea, creatinine, LDH, CK, malondialdehyde (MDA), and nitric oxide (NO), while increasing the levels of glutathione (GSH), catalase (CAT), and glutathione-S-transferase (GST). Histopathological investigations have revealed that Ovo-A restored the renal and muscular structure.

Conclusion:The current study showed that Ovo-A has a protective effect on kidneys and muscles in obese rats. Ovo-A enhances renal and muscular functions by inhibiting LDH and CK activities and improving the antioxidant system. Ovo-A is more effective in the high dose.
