Identification of the differentially expressed and prognosis-related genes in the TCGA cohort. (A) Volcano map showing the differentially expressed genes between normal and tumor tissues. The X axis indicates the -log(P-value), and the Y axis indicates the log2(fold change). Red dots represent upregulated genes; green dots represent downregulated genes. (B) Venn diagram showing the 47 DEGs that also had prognostic value. The left half of the Venn diagram shows the differentially expressed genes between normal and tumor tissues. The right half of the diagram shows the prognosis-related genes. (C) Univariate Cox regression analysis of the 47 overlapping genes. (D-E) The gene ontology (GO) enrichment terms (D) and KEGG pathways (E) of the 47 overlapping genes were both concentrated mainly in lipid metabolic processes
