GSEA revealed the positive enrichment of gene sets encoding oxidative phosphorylation (the Broad Hallmark Gene Set)- and ATPase activity (Gene Ontology Term)-related molecules in the DAP3-NC groups of both Huh7 and Hep3B cells (Fig. 3C, Supplementary Fig. S3C), revealing that DAP3 plays an important role in mitochondrial activity in HCC cells. Here, DAP3 is linked to hepatocellular carcinoma.
