中文摘要
环境中的亲电体暴露于培养细胞和实验动物中,会导致PTP1B和Keap1等传感器蛋白的活性硫醇发生共价或氧化修饰,从而分别激活EGFR和Nrf2。我们的发现表明,环境中的亲电体可以侵入细胞,然后以浓度依赖的方式调节细胞信号转导途径(如初始反应、细胞增殖和凋亡细胞死亡)
英文摘要
Exposure of environmental electrophiles to cultured cells and experimental animals caused a covalent or oxidative modification of the reactive thiols of sensor proteins such as PTP1B and Keap1, thereby activating EGFR and Nrf2, respectively. Our findings suggest that environmental electrophiles invade into cells, and then can modulate cellular signal transduction pathways (e.g., initial response, cell proliferation and apoptotic cell death) in a concentration-dependent manner
