Luciferase reporter gene expression and cell survival rate. a, c The evaluation of transfection efficiency and cell survival rate with chlorpromazine (10–100 μM) and wortmannin (10–100 nM) treated Hep-2 cells. Lipofectamine 2000 was used as positive control in transfection. Cell survival rate was determined with the MTT method with non-treated cells as control. All results are expressed as mean ± SD (n = 4). b, d RLU/survival rate with chlorpromazine (10–100 μM) and wortmannin (10–100 nM) treated Hep-2 cells
