19 PDEGs of G2/M checkpoint and P53 pathway identified from 8701 DEGs in TCGA-STAD cohort. (A) Volcano plot revealing 8701 DEGs between normal tissue and tumor tissue of 375 patients. (B) The expressions of 40 prognostic genes of G2/M checkpoint and P53 pathway in normal tissue and tumor tissue. (C) Venn diagram showing 19 PDEGs by the intersection of two gene sets. (D) The overview of the expression of 19 PDEGs among 399 G2/M checkpoint and P53 pathway genes. *P < 0.05, **P < 0.01, ***P < 0.001.
