摘要
表皮生长因子受体(epidermal growth factor receptor,EGFR)为典型的受体酪氨酸激酶,能够与多种配体结合,在细胞增殖、存活、黏附、分化和凋亡等生命活动中发挥重要作用。EGFR及其介导的信号通路的异常与肿瘤的发生发展密切相关。很多环境理化因素可通过影响EGFR磷酸化、或其结构功能和细胞分布、或其配体和其它相关分子表达,干预EGFR信号转导过程、影响靶基因的表达从而最终影响细胞生命活动。文中就此做一简要综述,以期更好地理解环境理化因素引起的细胞应激以及致突变致癌的表遗传分子机理。
Epidermal growth factor receptor (EGFR)is a classic protein tyrosine kinase receptor ,which plays an important role in cell proliferation ,survival ,adhesion ,differentiation and apoptosis. Abnormality of EGFR and its signaling are closely associated with tumor initiation and development. Many environmental physical and chemical agents can interfere with EGFR and its signal transduction pathways via affecting its phosphorylation, conformation and function, or distribution on cell membrane, finally influencing gene expression and cell fate. This review focuses on the recent progress of above aspects for further understanding of epigenetic mechanisms of cellular stress and carcinogenesis related with environmental agents.
