PTGS2 and breast cancer: Lastly, from the 84 breast cancer genes used, six genes (CSF1, SNAI2, PTGS2, PTEN, BRCA2, and EGFR) were found to be regulated by hsa-miR-128-3p while nine genes (AR, ATM, CCND1, CDK2, IGF1, IGF1R, TP53, IL6, and ABCB1) were regulated by hsa-miR-223-3p and hsa-miR-223-5p (Figure 3A and 3B).
