Figure 4. Gene mutation and gene set enrichment analyses. (A) Mutational profiles of the antioxidant genes included in the signature of sarcoma (obtained from cBioPortal). (B) Gene ontology (GO) functional annotation terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways enriched in the OS high-risk group. (C) GO functional annotation terms and KEGG pathways enriched in the DFS high-risk group.
