Figure 4. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Disease Ontology (DO) enrichment analyses. (A) Venn diagram for obtaining hub genes by taking the intersection. (B) GO enrichment analysis circle showing gene’s biological process, molecular function, and cellular component. (C) DO analysis of the relationship between cancers and gene ratio. (D) KEGG pathway map. Different colors represented different pathways, and the value of logFC represented the degree of expression.
