Figure 2. Functional enrichment analysis of DEUPSGs in HNSCC. (A–C) The top ten enriched terms in the GO analysis belonged to biological process (A), cell component (B), and molecular function (C) for DEUPSGs are demonstrated using an enriched scatter diagram. (D) The enriched pathways of the KEGG pathway analysis are showed using a scatter diagram. GO, gene ontology; KEGG, Kyoto Encyclopedia of Genes and Genomes.
