A RSD analysis of mass spectrum results. B Volcano plot showing the differentially expressed proteins in NUGC-4 cells following GPx2 knockdown. C, D GPx2 and KYNU expression in proteomic analysis following GPx2 knockdown. E, F GO analysis and KEGG analysis of the significantly differentially expressed proteins in NUGC-4 cells following GPx2 knockdown. *P < 0.05, **P < 0.01.
