title: Effect of oxidative stress on fluoride-induced apoptosis in primary cultured Sertoli cells of rats.
abstract: This study examined the effect of oxidative stress on the apoptosis of Sertoli cells induced by sodium fluoride (NaF). Cell viability, reactive oxygen species, malondialdehyde content, superoxide dismutase activity, mitochondrial membrane potential, and apoptosis were measured after the rat Sertoli cells were exposed to various concentrations of (0, 6, 12, and 24 μg/ml) sodium fluoride in the presence and absence of 2 mM N-acetylcysteine (NAC) for 24 h. The present study showed that decrease in cell viability and excessive oxidative stress were observed in NaF-treated cells. The treatment with NAC restored the decreased cell viability and excessive oxidative stress. Moreover, fluoride exposure decreased mitochondrial membrane potential and increased apoptosis in Sertoli cells. NAC was also found to suppress a loss of mitochondrial membrane potential and the percentage of apoptosis in NaF-treated Sertoli cells. This study proved that oxidative stress probably play a major role in NaF-induced apoptosis of Sertoli cells.
