For Group B vs Group A, DEGs showed significant enrichment in multiple GO categories: ‘circadian regulation of gene expression’ and ‘oxidative phosphorylation’ (Biological Process), ‘inner mitochondrial membrane protein complex’ (Cellular Component), and ‘phosphoprotein phosphatase activity’ (Molecular Function) (Figure 5A); KEGG analysis revealed enrichment in ‘Hepatocellular carcinoma’ (Figure 5B); and DO analysis indicated enrichment for various neoplastic diseases (Figure 5C). This evidence concerns the gene PPP1R2 and hepatocellular carcinoma.
