KEGG pathway is enriched in oxytocin signaling pathway, circadian rhythm, hypertrophic cardiomyopathy (HCM), glucagon signaling pathway, cardiac muscle contraction, adrenergic signaling in cardiomyocytes, influenza A, hepatitis C, herpes simplex infection, and glycolysis (Figure 6(b)). The gene discussed is OXT; the disease is hepatitis C virus infection.
