XCL2 and breast cancer: We discovered a significant positive correlation between LCP1 expression and various chemokines, namely CCL2(r= 0.359, P<0.001), CCL3(r = 0.335, P<0.001), CCL4(r = 0.511, P<0.001), CXCL9(r= 0.597, P<0.001), XCL1(r = 0.51, P<0.001) and XCL2(r = 0.501, P<0.001) in BC (Fig. 4A-G).
