Fig. 2From: Identification and functional study of GATA4 gene regulatory variants in atrial septal defectsRelative 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 < 0.01Back to article page
