摘要 芳基烃受体属于碱性螺旋-环-螺旋蛋白超家族的转录因子。环境污染物激活芳基烃受体,上调cyp1a的表达,诱导自身的Ⅰ相代谢,增加代谢中间体的生成,代谢中间体与生物大分子结合,造成机体损伤。环境污染物同时可激活芳基烃受体并改变一系列与细胞增殖、细胞周期进程和凋亡相关基因的表达,导致机体损伤并诱发肿瘤。 Aryl hydrocarbon receptor (AhR) is a member of the basic helix-loop-helix/Per-Arnt-Sim (bHLH/PAS) superfamily. Environmental pollutants upregulate cypla by activating AhR, and increase the production of intermediates by inducing the phaseⅠ metabolism of themselves. Intermediates conjugating with biomacromolecule cause injury. AhR activated by environmental pollutants modifies a series of geneexpression involved in cell proliferation, cell cycle and apoptosis, which cause injury and cancer.
