In order to define the therapeutic role of Aur-A in TNBC, we detected Aur-A expression in various types of breast cancer cell lines (TNBC: MDA-MB-231, MDA-MB-468, BT-549; Luminal A: MCF-7, ZR75-1; Luminal B: BT-474, MDA-MB-435; HER2+: SKBR3) [37] and primary samples. This evidence concerns the gene AURKA and breast cancer.
