CCL26 and neoplasm: Using a microarray analysis of 84 cytokines/chemokines in tumor samples and their adjacent normal lung tissues of eight HPR NSCLCs, we found that the expression of four cytokines (IL-1F5, IL-1F9, MIF, and SPP1) and seven chemokines (CXCL13, CCL7, CCL20, CCL26, CXCL6, CXCL9, and CXCL14) was increased in tumors compared with their counterpart normal lung tissues (Figure 1A).
