EGR1 was upregulated in 40% breast cancer tissues, and miR-20b was elevated in 30% breast cancer tissues examined: upregulated EGR1 correlated significantly with upregulated miR-20b in the normal, benign, and tumor tissues tested (Fig. 6A and B; r=0.99, p=0.032). This evidence concerns the gene EGR1 and breast carcinoma.
