Cetuximab enhanced cisplatin-induced apoptosis and antiproliferation effect in HNE1 cells. HNE1 cells were treated with cetuximab, cisplatin, or the double agents for 48 h before the cells were analysed by flow cytometry ((a), (b), (c), and (d)). Multiplication capacity of cells in different treatment groups is shown in ((e), (f)) via a colony formation assay. ^∗ p < 0.05 versus cisplatin treatment alone.
