To explore the effect of CXCL8-CXCR2 signaling in nasopharyngeal carcinoma, we performed immunohistochemistry staining for CXCR2 and CXCL8 in an NPC tissue microarray and found CXCR2 localized in both tumor cells and stromal cells; CXCL8 was frequently observed in the cytosol of tumor cells (Figure 1A and Supplementary Table). The gene discussed is CXCL8; the disease is nasopharyngeal carcinoma.
