高度选择性,细胞可渗透的EGFR抑制剂;a highly selective, cell-permeable EGFR inhibitor;EGFR抑制剂是一种细胞可渗透的化合物,是EGFR(表皮生长因子受体)的高度选择性抑制剂。EGFR的抑制已显示出诱导细胞凋亡。机理研究表明,EGFR抑制通过下调抗凋亡蛋白survivin表达而发生。已经观察到Survivin的下调在抑制PI3K-AKT信号传导途径后发生。其他实验报告称,EGFR抑制剂还诱导凋亡蛋白BIM的上调。;EGFR Inhibitor is a cell permeable compound that is a highly selective inhibitor of EGFR (epidermal growth factor receptor). Inhibition of EGFR has been shown to induce apoptosis. Mechanistic studies have shown that EGFR inhibition takes place via downregulation of antiapoptotic protein survivin expression. Downregulation of Survivin has been observed to take place following inhibition of the PI3K-AKT signaling pathway. Additional experiments report that EGFR inhibitors also induce upregulation of proapoptotic protein BIM.
