As FOXA1 was significantly expressed in hormone-receptor-positive breast cancer (HR+ BC) patients in Figure 2, Figure 3 and Figure 4, we confirmed the FOXA1 protein level in three different hormone-receptor-positive breast cancer (HR+ BC) cell lines (T47D, MCF-7, and BT-474) and three different TNBC cell lines (BT-549, MDA-MB-231, and MDA-MB-468). This evidence concerns the gene NR4A1 and breast carcinoma.
