ACE2 and cardiac hypertrophy: Among top pathways shared between complete ACE2 networks, subnetworks and ACE2 network in cardiomyocytes, we observed many terms directly associated with heart functions, for example, microRNAs in cardiomyocyte hypertrophy, EGF receptor transactivation by G protein-coupled receptors (GPCRs) in cardiac hypertrophy, actions of nitric oxide in the heart, corticosteroids and cardio-protection.
