Figure 2. Correlation of expression level of eRNAs with the enhancer’s target gene or flanking regions.

Each bar represents the Pearson correlation between the expression level of eRNA and target gene (red), eRNA and 0–1 k flanking region (dark green), eRNA and 1–2 k flanking region (green), or eRNA and 2–3 k flanking region (light green). The expression level is calculated by BPKM. Significance is denoted by ^*p-value < 0.001; ^***p-value < 10⁻⁵.
