Colony formation assay was used to detect the cell growth activity. (A) Clones of transfected cells were less than control cells. The antitumor effects of 5-FU in transfected cells were more profound than those in the control cells. (B) Relative colony numbers of transfected cells and control cells. Less growth activity was found in transfected cells compared to control cells (*P < 0.05).
