Artificial hTERT promoter can drive downstream gene expression efficiently and selectively in bladder cancer cell. Luciferase activity was detected using dual luciferase assay system at 48 h after transfection. The activity of artificial hTERT promoter was significantly higher than that of wild-type hTERT promoter in bladder cancer cells. Nevertheless, both the activity of artificial hTERT promoter and that of wild-type hTERT promoter were weak in NHF. Data are indicated as mean ± S.D.
