Ubiquitin Ligase Cbl-b Is Involved in Icotinib (BPI-2009H)-Induced Apoptosis and G1 Phase Arrest of EGFR Mutation-Positive Non-Small-Cell Lung Cancer
Figure 4
Icotinib-induced apoptosis in HCC827 cells. (a) and (b) Cells were exposed to 0.01 and 0.1 μmol/L icotinib for 24 h, and the cell cycle was analyzed by flow cytometry after staining with propidium iodide. (c) Expression of PARP and caspase-3 and -8 was analyzed by Western blotting. β-Actin was used as the internal control. Data are representative of one of three independent experiments.
