iKeap1 activates Nrf2 signaling to protect myocardial cells from oxygen glucose deprivation/re-oxygenation-induced oxidative injury.

Nuclear factor E2-related factor 2 (Nrf2) activation could efficiently protect myocardial cells from oxygen glucose deprivation/re-oxygenation (OGDR). An ultra-large structure-based virtual screening has discovered iKeap1 as a novel, direct and potent Keap1 inhibitor. Here we found that iKeap1 efficiently activated Nrf2 signaling in H9c2 myocardial cells and primary murine myocardiocytes.

Tumour necrosis factor receptor-associated factors: interacting protein with forkhead-associated domain inhibition decreases inflammatory cell infiltration and cardiac remodelling after acute myocardial infarction.

Objectives: Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality worldwide. Post-AMI cardiac remodelling is closely related to the prognosis of AMI. The excess inflammatory responses could promote cardiac remodelling.
