title: Antioxidant defense system parameters in isolated fish hepatocytes exposed to bisphenol A - Effect of vitamin C.
abstract: In this study, isolated hepatocytes of pearl mullet (Alburnus tarichi) were exposed to bisphenol A (BPA) at concentrations of 25, 50, 100, and 200 μM for 24 h. Moreover, an in vitro antioxidant concentration of vitamin C (50 μM) was administrated to the culture medium along with the BPA exposures. Next, the antioxidant defense system parameters were analyzed. According to the results, the highest concentration of BPA (200 μM) proved to be severely toxic for the cells. The increased activities of superoxide dismutase (SOD) and glutathione-S-transferase (GST), the fluctuated activities of glutathione peroxidase (GPx), and the decreased content of reduced glutathione (GSH) were compared to the control group after the BPA exposures. Vitamin C co-administration was found to cause further increases in the SOD, GPx, and GST activities in some of the experimental groups and vitamin C could not restore the GSH content. Malondialdehyde (MDA) levels were observed to be unaffected in all exposure groups. These results show that BPA causes alterations in the antioxidant defenses of the isolated fish hepatocytes. In addition, vitamin C co-administration along with BPA was found to be non-protective against BPA-induced oxidative stress, consequently, aggravated a negative BPA impact.
