CCL26 and breast cancer: The results revealed that CCL2 (Pr = 2.53e−05), CCL11 (Pr = 2.61e−08), CCL14 (Pr = 6.35e−06), CCL18 (Pr = 0.00218), CCL19 (Pr = 0.00868), CCL21 (Pr = 0.000135), CCL23 (Pr = 0.0134), CCL24 (Pr = 0.00147) and CCL26 (Pr = 3.78e-06) may play a significant role in the tumorigenesis in BC patients (Fig. 3).
