Finally, our results also highlight a strong and significant correlation between EPHA4 and TGFBR2 mRNA expression levels (r = 0.17, P < 0.0001) in more than 5000 breast cancer patients samples obtained from Breast Cancer Gene-Expression Miner v4.0 database (Fig. 8A). This evidence concerns the gene TGFBR2 and breast carcinoma.
