Through enrichment analysis, it was found that these DEGs were mainly enriched in microtubule cytoskeleton organization involved in mitosis, DNA metabolic process, cell cycle, DNA replication, p53 signaling pathway, cellular amino acid catabolic process, epoxygenase P450 pathway, PPAR signaling pathway, MAPK signaling pathway, IL-17 signaling pathway, etc. Among these enrichment items, some have been confirmed to be involved in the occurrence and development of HCC. The gene discussed is PPARA; the disease is hepatocellular carcinoma.
