Abstract
- Background and Aim: Cyclophosphamide (CP) chemotherapy is a significant iatrogenic component of premature ovarian failure (POF). The aim of this work was to evaluate the potential protective effects of donepezil, a centrally acting acetylcholinesterase (AChE) inhibitor, on CP-induced POF in mice.<br />Methods: 40 female Swiss albino mice were split into 5 equal groups: group 1 (control), group 2 (CP-POF); induced by intraperitoneal injection of CP on 8th day of the experiment, and group (3-5); mice received oral donepezil daily (1, 2, or 4 mg/kg, respectively) 8 days before CP injection. Mice were euthanized after 24 h of CP injection, and blood samples were collected to assay serum anti-Mullerian hormone (AMH) levels. Ovarian tissues were dissected, and the right ovary was processed for further assays of nitric oxide (NO), tumor necrosis factor-α (TNF-α), interlukin-6 (IL-6), nucleotide-binding domain-like receptor family, the Pyrin domain-containing 3 (NLRP3) inflammasome, and Toll-like receptor 4 (TLR-4), while the left one was processed for histopathological and immunohistochemical examination of nuclear factor-Kappa beta (NF-κB) and caspase-3.<br />Results: Donepezil, in a dose-dependent manner particularly (4 mg/kg), has an inhibitory action on NO (40 ± 2.85 vs. 28.20 ± 2.23, P < 0.001), proinflammatory cytokines (P < 0.001), the TLR-4/ NF-κB / NLRP3 inflammasome pathway (P < 0.001), and apoptosis (P < 0.001), with a significant elevation in the AMH levels (4.57 ± 1.08 vs. 8.57 ± 0.97, P < 0.001) versus CP-POF group.<br />Conclusion: Donepezil may be a potential protective agent against CP-induced POF in mice, but further research is needed to fully understand its therapeutic function experimentally and clinically.<br />Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.<br /> (Copyright © 2024 Elsevier Inc.
