To obtain the relevant target genes of CXHO in GC, we intersected the DEGs with target genes of CXHO and obtained 17 overlapping genes, namely, CCNA1, EPHX1, CYP1B1, MYLK, discoidin domain receptor 2 (DDR2), TGFB1, MMP2, FAP, CA9, SHH, CYP2C19, AKR1C3, PLA2G2A, MMP9, PKM, STS, and prostaglandin synthase COX-2 (PTGS2) (Fig. 4A). This evidence concerns the gene MMP2 and gastric cancer.
