Data from Ualcan revealed that the expressions of BMP2, CCL5, CCL15, CCL20, IL8, CD70, CSF2RA, CXCL1, CXCL16, CXCR4, TGFB2, GDF15, IL11, IL1R1, IL1RN, IL13RA2, IL32, IL2RB, IL2RG, IL22RA1, IL18R1, IL18RAP, INHBA, INHBB, INHBE, TNFRSF9, TNFRSF1B, and TNFRSF14 were significantly higher in GC tissues than in normal tissues (Supplementary Figure S8). This evidence concerns the gene CXCR4 and gastric cancer.
