Figure 2. Functional analysis of three subsets based on GDRGs. (A) GO BP for subset I genes. (B) KEGG enrichment analysis for subset I genes. (C) GO BP for subset II genes. (D) KEGG enrichment analysis for subset II genes. (E) GO BP of subset III genes. (F) KEGG enrichment analysis of subset III genes. GDRG: gastric cancer differentiation-related gene, GO: Gene Ontology, BP: biological process, KEGG: Kyoto Encyclopedia of Genes and Genomes.
