Although cisplatin (CDDP) is an effective anticancer agent, the ovotoxicity that can occur in female patients limits its use. Oxidative stress (OS) and inflammation are known to contribute to CDDP-induced ovotoxicity. Vanillic acid (VA) is a dietary herbal secondary metabolite with high free radical scavenging activity. It was aimed to evaluate the therapeutic effects of VA against CDDP-induced ovotoxicity in rats in this study for the first time. Ovotoxicity was achieved with a single dose of CDDP (5 mg/kg) in female rats. The therapeutic effect of VA was evaluated with 3-day administration of two different doses (5 and 10 mg/kg). While OS, inflammation, endoplasmic reticulum stress (ERS) and apoptosis markers were measured in tissue samples, the levels of reproductive hormones were determined in serum samples using colorimetric methods. The results showed that CDDP-induced nuclear factor erythroid 2-associated factor 2 (Nrf2) inhibition combined with increased OS, inflammation, ERS and apoptosis increased ovarian damage. VA treatments reversed these changes via activating Nrf2 pathway dose-dependently. In addition, histopathological findings also supported the biochemical results. VA may be a good therapeutic molecule candidate for CDDP-induced ovarian damage due to strong antioxidant and Nrf2 activator properties.
