The relationship between CCL26 expression and 5-year overall survival in other types of tumors was analyzed through the Kaplan-Meier plotter database (http://kmplot.com/analysis/index.php?p=service), and similar results were observed, with patients whose tumor cells highly expressed CCL26 having significantly shorter 5-year overall survival in head and neck squamous carcinomas, renal clear cell carcinomas, hepatocellular carcinomas, and lung carcinomas (Figures 3I–L). The gene discussed is CCL26; the disease is hepatocellular carcinoma.
