ELAVL1 and myocardial ischemia: Cardiac fibroblast (CFs) exosomes (CFs-Exos) carrying miR-133a can effectively inhibit cardiomyocyte pyroptosis in myocardial ischemia/reperfusion (MI/R) rat models and hypoxia/reoxygenation (H/R) injury models, and suppressing ELAV-like RNA-binding protein 1 (ELAVL1) expression achieves the cardioprotective function of CFs in vivo and in vitro (41).
