To evaluate the relationship between CXCL5 and clinical data, we used TISIDB (http://cis.hku.hk/TISIDB/index.php) to analyze CXCL5 expression in NSCLC tissues classified by clinical stage in the TCGA database and found that CXCL5 expression was positively associated with clinical stage in LUAD but not LUSC (Fig. 7a, b). The gene discussed is CXCL5; the disease is non-small cell lung carcinoma.
