Furthermore, neutrophil abundance was significantly associated with the expression of CXCL1, CXCL2, CXCL3, and CXCL5, as well as CXCL‐CXCR2 signaling in ccRCC metastasis samples from the TCGA‐KIRC cohort (Figure S7G, Supporting Information), consistent with the findings in our current study. The gene discussed is CXCL1; the disease is nonpapillary renal cell carcinoma.
