| Popis: | Aims Cisplatin (CP) is a widely used broad-spectrum antineoplastic agent used to treat a variety of human malignancies. Neurotoxicity is clinically evident in patients who have undergone a full course of chemotherapy. The aim of this study was to investigate the possible protective effects of thymoquinone (TQ) and geraniol (Ger) against CP-induced neurotoxicity in rats. Main methods Forty male Wistar albino rats were allocated into four groups as follows: normal control, CP-induced neurotoxicity, CP + TQ and CP + Ger. Key findings Our results demonstrated that simultaneous treatment with either TQ or Ger and CP significantly abrogated oxidative stress and downregulated the apoptotic markers p38 mitogen-activated protein kinase (MAPK), STAT-1, p53, p21 and MMP9; FMO3, however, was insignificantly decreased. In addition to the biochemical results, we assessed the histopathological findings, which confirmed the protective effect of TQ and Ger against the brain damage induced by CP. Significance The results of the present study indicate that simultaneous treatment with either TQ or Ger as natural antioxidants can provide protection against cisplatin-induced neurotoxicity in rats by attenuating oxidative stress and cell apoptosis. |
