ABSTRACT
Di-(2-ethylhexyl) phthalate (DEHP) is an environmental endocrine disruptor widely employed in plastic bags, industrial paints, cosmetics and food packaging, which has been reported to be harmful to human physical health. Many studies have shown that DEHP causes reproductive system toxicity, but its cytotoxicity to islet cells is few to unknown. In our research, it was found that DEHP could induce apoptosis in INS-1 cells via autophagy and oxidative stress. Taurine, a sulfur-containing ß-amino acid, could reverse DEHP-induced oxidative stress imbalance. Meanwhile, taurine could reduce DEHP-induced excessive autophagy. The interaction between oxidative stress and autophagy has been investigated in this study. After pretreated with autophagy interventional agents, it was found that autophagy was capable of alleviating oxidative stress and ROS production in DEHP-treated INS-1 cells. And down-regulated ROS production by NAC could also turn over uploaded autophagy. Our research provides a perspective about the mechanism of cytotoxicity of DEHP to INS-1 cells and taurine protective effect.
