The result represented that upregulated DEGs were significantly associated with 5 KEGG pathways, including ‘hepatocellular carcinoma,' ‘Kaposi sarcoma-associated herpesvirus infection,' ‘phosphatidylinositol signaling system,' ‘circadian entrainment,' and ‘apelin signaling pathway' (Figure 3(e), Table 4). The gene discussed is APLN; the disease is Kaposi's sarcoma.
