Establishment of osimertinib-resistant non-small cell lung cancer cells. (A) Effects of osimertinib on cell viability were analyzed using an MTT assay in HCC827 and HCC-827/OR cells. (B) Representative profiles of apoptosis induced by osimertinib and (C) quantitative results were obtained using PE/FITC staining in HCC827 cells. (D) Representative profiles of apoptosis induced by osimertinib and (E) quantitative results were obtained using PE/FITC staining in HCC827/OR cells. Data are presented as the mean ± SD from three independent experiments. *P<0.05 vs. DMSO treatment group.
