Therefore, there were 19 DEGs of them (NOX5, ZFP36, DUSP1, TSC22D3, TXNIP, GABARAPL1, CDO1, TGFBR1, HAMP, NOX4, NNMT, CXCL2, AIFM2, SLC1A4, NF2, SP1, GLS2, MYB, and PSAT1) associated with the prognosis of GC, including 12 upregulated genes and 7 downregulated genes (Figures 1(b) and 1(c)). This evidence concerns the gene NOX4 and gastric cancer.
