MZF1 and breast carcinoma: In search for mechanisms responsible for the upregulation of MZF1 during breast cancer progression to IDC, we screened the MZF1 3′-untranslated region (UTR) for putative miRNA binding sites in microRNA.org (http://www.microrna.org/microrna/home.do); a miRNA target prediction resource based on the MiRanda algorithm25.
