KEGG pathway enrichment showed enrichment in pathways in cancer, as well as the proteoglycans in cancer pathway, Ras signaling pathway, PI3K/Akt signaling pathway, FoxO signaling pathway, TNF signaling pathway, nonalcoholic fatty liver disease (NAFLD), and hepatitis C, which is strongly associated with the development of HCC. The gene discussed is PIK3CD; the disease is hepatocellular carcinoma.
