Overexpressed miRNAs in this sample group are known for their tumor-suppressive roles in (breast) cancer: the miR-200 family (miR-200a, miR-200b, miR-200c, and miR-141), the let-7 family (let-7a, let-7f, and let-7g), and NFκB-regulating miRNAs (miR-146a and miR-155). Here, NFKB1 is linked to breast carcinoma.
