体外研究

Erlotinib作用于HNS人头部和颈部肿瘤细胞,有效抑制EGFR自磷酸化,HNS人头部和颈部肿瘤细胞是表达高水平EGFR的细胞系。[1] Erlotinib对SBC-5细胞增殖没有作用效果。相反, Erlotinib 显著抑制PC-9细胞增殖,这种作用存在剂量依赖性,PC-9细胞在EGFR基因第19外显子含缺失突变。Erlotinib处理也不会影响SBC-5细胞迁移。[2] Erlotinib 抑制HPAC细胞和Capan-1细胞生长, IC50 分别为1.1和3µM。10 uM Erlotinib 抑制EGFR在 Y845 (Src依赖性磷酸化) 和和Y1068(自磷酸化)位点磷酸化。[3] Erlotinib 只有作用于最敏感的细胞株时,抑制细胞外信号调节激酶, Akt, 和S6。[4]

Erlotinib induces colocalization of BAX and cytochrome c in PC-9 cells undergoing apoptosis. Cells were grown in Lab-Tek II chambers and treated with 100 nM erlotinib or DMSO for 48 h, fixed and immunostained with antibodies against BAX (green) and cytochrome c (red) or with DAPI to detect DNA (blue). Cells were imaged by confocal microscopy.
