miR-608 significantly promoted the anti-proliferation effect of gefitinib in PC9 cells (a) and H1299 cells (b). Elevated miR-608 expression was observed in both cell lines (c). All experiments were performed in triplicates in three independent transfection experiments and each value represents mean ± standard deviation (SD). *P < 0.05, **P < 0.01
