In the clinical NPC samples, the expression of chemokines, such as CXCL8 (IL-8), TNF alpha, CCL-20 (MIP-3a), CCL-2 (MCP-1), and CXCL10 (IP-10), has been reported (Klein et al., 1996; Ren et al., 2004; Hsu et al., 2008; Lo et al., 2013). This evidence concerns the gene CCL20 and nasopharyngeal carcinoma.
