NR4A1 and breast cancer: By comparing the deregulated miRs in the hormone-receptor-positive cell lines BT-474 and MCF to the ones in the triple-negative BC cell line Hs-478T, it can be seen that miR let-7b, let-7d, miR-15a, miR-17, miR-18a, miR-20a, miR-191 and miR-301a_3p are differentially expressed.
