In the molecular function (MF), binding, catalytic activity, transcription regulator activity, transporter activity, In particular, KEGG pathway analysis is rich in central carbon metabolism in cancer pathway, HIF-1 signaling pathway, pathways in cancer, hepatitis B pathway, relaxin signaling pathway, Kaposi sarcoma-associated herpesvirus infection pathway (Figure 5D). The gene discussed is HIF1A; the disease is Kaposi's sarcoma.
