Hypoxia-inducible factors are stabilized and provide protection from ischemia and reperfusion injury in the setting of myocardial ischemia.In the setting of ischemia, myocyte-specific hypoxia-inducible factor 2A induces expression of amphiregulin, which is an epidermal growth factor that binds to epidermal growth factor receptor 1 (ERBB1) in the myocardium.
