The gene network was significantly enriched with 51 KEGG pathways (FDR-p < 0.05; Table S4) that predominantly consisted of signaling pathways, such as Wnt, cancer, Notch, thyroid hormone, TGF-β, glucagon, as well as adherens junction and viral infections (e.g., HTLV-1, herpesvirus, EBV, measles). Here, GCG is linked to viral infectious disease.
