Abstract：Objective To investigate the influence of icotinib hydrochloride on apoptosis of non-small cell lung cancer cell (NSCLC)-HCC827 and the protein expression levels of EGFR downstream signaling pathways in vitro.Methods The influence of icotinib hydrochloride on proliferation of HCC827 cell was detected by MTT,and the effects of icotinib-induced apoptosis of HCC827 cell were observed by flow cytometry,moreover, the expression levels of EGFR signaling pathways downstream proteins including epidermal growth factor receptor (EGFR),protein kinase B (AKT),extracellular signal regulating EGFR kinase (ERK),p-EGFR,p-AKT,p-ERK and Survivin were detected by Western Blot.Results The icotinib hydrochloride had inhibitory effects on HCC827 cell proliferation and could induce apoptosis of HCC827,with a concentration dependent and time dependence manner (P<0.05).With the increase of icotinib concentration,the expression levels of EGFR signaling pathways downstream protein including p-EGFR,p-AKT,p-ERK and Survivin were significantly down-regulated (P<0.05).Conclusion The icotinib hydrochloride can effectively inhibit HCC827 cell proliferation and induce apoptosis of HCC827 cells by inhibiting the expressions of EGFR signaling pathways downstream protein.
