Data in GEPIA revealed that the expressions of CCL5, CCL15, CCL20, CSF2RA, CXCL1, CXCL8, CXCL16, CXCR4, GDF15, IL1RN, IL2RB, IL2RG, IL22RA1, INHBA, TNFRSF1B, and TNFRSF14 were significantly higher in GC tissues than in normal tissues (Supplementary Figure S7). This evidence concerns the gene IL2RG and gastric cancer.
