We also included tissue biopsy and sera from benign fibroadenoma for comparison and correlated their tissue/sera expression profile of these six miRNAs with that of TNBC patients and breast cancer cell lines, MDA-MB-231 (TNBC, ER-/PR-/Her2neu-) and MCF-7 (DPBC, ER+/PR+/Her2neu-) along with normal breast epithelial cell line (MCF-10A). Here, PGR is linked to breast carcinoma.
