A549/D16 and A549/V16 sublines were treated with VER (A, D), DIL (B, E), and NIF (C, F) alone, respectively, or co-treated with DOC (A, B, and C) or VCR (D, E, and F) for 48 hrs and incubated with fresh medium for 10 days and the colonies were calculated. The data were collected and normalized to the control set that without CCBs. *p<0.05 was considered statistically significant.
