Abstract

Exposure to the food contaminant acrylamide and its reactive epoxide metabolite glycidamide (GA) induces reactive oxygen species (ROS)-mediated oxidative stress and subsequent cellular death. Recent studies have revealed that the toxic effects of acrylamide may be due to GA, especially on male reproductive system cells. In this regard, it is important to determine the effects of GA on Sertoli cells, which are essential cells for the male reproductive system. Antioxidants should be consumed in sufficient quantities to minimise the effects of environmental pollutants. This study aimed to determine the direct toxic effects of GA and protective effects of vitamin C (VitC) against GA-induced damage in Sertoli cells by measuring cell viability, cytotoxicity, lipid peroxidation, ROS, antioxidant enzyme levels, apoptosis and DNA damage. Sertoli cells were exposed to GA for 24 hours at four different concentrations (ranging between 1 and 1000 mu M) and in addition to these GA concentrations to VitC (50 mu M). The results of cytotoxicity markers, such as cell viability and lactate dehydrogenase (LDH) showed that GA significantly reduced cell viability and increased LDH levels. We also found that GA induced overproduction of intracellular ROS, increased lipid peroxidation in cellular membrane and triggered cell apoptosis and genotoxicity. In addition, VitC supplementation ameliorated the adverse effects of GA on Sertoli cells. Consequently, these findings suggest that GA may damage the cell function in Sertoli cells, depending on the concentration. Additionally, it was evidenced that VitC has an ameliorative effect on toxicity caused by GA.
