Exenatide improves cisplatin induced ovarian damage through NLRP3, Nrf-2, and TLR4 pathways.

Objective: Cisplatin (CP) toxicity causes ovarian damage by oxidative stress, inflammation and fibrosis. The aim of the present study is to investigate the possible beneficial effects of exenatide on the experimental ovarian damage model produced by CP.

Method: For 14 rats, CP was administered by intraperitoneally (i.p) twice a week for 5 weeks. No drug was administered to the remainder of rats (n = 7) (Group 0). The rats taken CP were divided into two groups. Group 1 rats (n = 7) were given 1 mL/kg/day saline i.p., and Group 2 rats (n = 7) was given with 20 μg/kg/day exenatide.

Results: The number of primordial, primary, secondary, and tertiary follicle was significantly lower in Group1 compared with Group 0 and Group 2. The ovarian fibrosis percent was significantly higher in Group 1 than Group 0 and 2. The plasma anti-Mullerian hormone value was lower in Group1compared with Group 0 and 2. Over Nuclear factor-erythroid factor 2-related factor 2 level, Over Toll-like receptor 4 level and over nucleotide-binding domain leucine-rich repeat and pyrin domain containing receptor 3 were higher in Group 1 compared with Group 0 and 2.

Conclusion: Exenatide has possible beneficial effect on ovarian damage induced by CP by anti-inflammatory actions and can be a promising candidate for ovarian damage caused by CP.
