The results revealed that 15 chemokine ligands (CXCL9, CXCL10, CXCL11, CXCL12, CXCL13, CCL3, CCL4, CCL5, CCL11, CCL18, CCL20, CCL21, CCL28, CX3CL1, and XCL2) were differentially expressed in ccRCC tissues (n = 523) compared with normal kidney tissues (n = 100) (Figure 1). Here, CXCL11 is linked to nonpapillary renal cell carcinoma.
