Özet

Reproductive toxicity is a serious side effect of cisplatin (CP) chemotherapy. Gentisic acid (GTA) is a phenolic acid with strong antioxidant properties. Here, we aimed to determine therapeutic effect of GTA against CP-induced testicular toxicity in rats for the first time. Male Sprague-Dawley rats received a single dose of CP (5 mg/kg; intraperitoneal) and treated with GTA (1.5 and 3 mg/kg; intraperitoneal; 3 consecutive days). The levels of oxidative stress (OS), inflammation, endoplasmic reticulum stress (ERS) and apoptosis biomarkers were assessed in the testicular tissue of rats. In addition, how CP affects the nuclear factor erythroid-2-related factor 2 (Nrf2) pathway and the effect of GTA on this situation were also addressed in the testicular tissue. CP admin-istration induced histopathological changes in testicular tissue of rats with a significant increase in OS, inflammation, ERS and apoptosis biomarkers and a decrease in antioxidant capacity and Nrf2 expression levels. Administrations of GTA resulted in an amelioration of these altered parameters. These data suggest that GTA may be a potential therapeutic agent against CP-induced testicular toxicity. Activation of the Nrf2 pathway plays a key role of this therapeutic effect of GTA.
