Fig. 5. Ectopic NCAPG renders trastuzumab resistance in breast cancer.
a Representative micrographs (left) and quantification (right) of colony formation assays for SKBR3 and BT474 cell lines with or without overexpression of NCAPG under treatment with trastuzumab (10 μg/mL). b Cell viability measured by MTT assay. c Flow cytometry analysis of apoptosis by Annexin V-FITC/PI staining (left) and histograms (right) indicating the percentage of Annexin V+ cells. d Representative images (left) and quantification (right) of fluorescence micrographs of TUNEL-stained cells in the indicated cells treated with trastuzumab (10 μg/mL). Error bar represents the mean ± SD of three independent experiments. *P < 0.05.
