CCR3 and hepatocellular carcinoma: Given the paucity of adjacent non-tumor tissue samples in the TCGA database, we increased adjacent non-tumor tissue samples through the GTEx database and found that CCL14 (Figure 10A) was significantly highly expressed in adjacent non-tumor tissue, while CCL20 (Figure 10B) and CCR3 (Figure 10C) were significantly less expressed when compared with HCC tissue.
