KDM3A and myocardial infarction: In addition, lncRNA CAIF is shown to suppress autophagy and alleviate myocardial infarction by blocking p53-mediated cardiac troponin transcription [30], and lncRNA H19 can reduce myocardial injury and maladaptive cardiac remodeling caused by myocardial infarction by regulating KDM3A [31].
