Once myocardial infarction occurs, stem cell exosome-derived lncRNA-UCA1 [150], miR-146a-5p [151], and miR-125b-5p [152] were shown to reduce myocardial apoptosis, while lncRNA KLF3-AS1 was found to decelerate the onset and development of myocardial infarction [153]. The gene discussed is KLF3; the disease is myocardial infarction.
