As expected, the transcriptional levels of CXCL1 (p = 3.27e−2), CXCL2 (p = 2.62e−12), CXCL5 (p = 4.03e−10), CXCL9 (p = 1.62e−12), CXCL10 (p = 1.62e−12), CXCL11 (p = 1.62e−12), and CXCL16 (p = 1e−12) in RCC tissues were significantly elevated while the transcriptional levels of CXCL12 (p = 1.63e−12) were significantly reduced (Figure 2). This evidence concerns the gene CXCL16 and renal cell carcinoma.
