Enhancer activity identification of tnni1b-ECR183 and tnni1b-ECR183-d2 by the luciferase assay in the HEK293 (A) and HL1 cell lines (B). (C) Putative TFBS positions and mutations. Analysis of the enhancer activity of tnni1b-ECR183-d2 after putative TFs were overexpressed (D) or after NKX2.5 (E) and JUN (F) binding sites were mutated. One-way ANOVA was used to test for homogeneity of variance, and Bonferroni’s test was used to correct for multiple comparisons (A, B, D). A
