In addition, the results shown in Supplementary Table 1 revealed significant associations in COAD + READ between tumor stage and expression of CXCL1 (P = 0.0345), CXCL2 (P = 0.0156), CXCL3 (P = 0.0344), CXCL9 (P = 0.0122), CXCL10 (P = 0.0108), and CXCL11 (P = 0.0227) expression. The gene discussed is CXCL2; the disease is neoplasm.
