As shown in Figure 4A,B, the immunoblotting data clearly suggest that the expression of AnxA2 is high in TNBC cell lines (HCC1937, HCC70, and HCC1395 cells) compared to ER+ (ZR75-1 cells), ER+/PR+ (MCF7, T47D, and HCC1428 cells), HER2+ (SK-BR-3 cells), and ER+/PR+/HER2+ (BT474 cells) breast cancer cell lines. The gene discussed is ANXA2; the disease is breast cancer.
