N-acetyl-cysteine protects chicken growth plate chondrocytes from T-2 toxin-induced oxidative stress.

T-2 toxin is now considered to be related to bone malformation such as incomplete ossification, absence of bones and fused bones. In this study, primary cultures of chicken tibial growth plate chondrocytes (GPCs) were treated with various concentrations of T-2 toxin (5, 50, and 500 n m) in the absence and presence of N-acetyl-cysteine (NAC) to investigate the effects of the antioxidant NAC on T-2 toxin-induced toxicity. Our results showed that T-2 toxin markedly decreased cell viability, alkaline phosphatase activity and glutathione content (P < 0.
