Relative activities of GATA4 gene promoters with or without regulatory variants in H9c2 cells. All transfection experiments were performed three times independently, in triplicate. The results were represented as means ± SEM. Bar graph represented the mean and error bar indicated SEM. Empty pGL3-basic was used as a negative control. Activity of wild type GATA4 gene promoter was set as 100%. WT, wild type. *P < 0.01
