Tissue specificity of ERE expression in healthy human tissues. Tissue specificity indexes were computed for ERE families as well as annotated genes. a Barplots showing the number of TRGs and TREs for each of the 32 healthy human tissues analyzed. b Pie charts depicting the proportions of the 809 ERE families (left panel) or TREs (right panel) belonging to the LINE, LTR, and SINE groups (chi-squared test, *P ≤ 0.05). c Histogram showing the number of tissues in which each identified TRGs and TREs are overexpressed
