Research progress of targeting miRNAs in prevention and treatment of ventricular remodeling after myocardial infarction / 中国药理学通报

ABSTRACT

Myocardial infarction is one of the leading causes of death worldwide, appearing at the last point of atherosclerotic plaque progression and unstable rupture. Impaired cellular signals after myocardial infarction leads to maladaptive changes, leading to ventricular remodeling and heart failure. MicroRNAs (miRNAs/miRs) are a kind of non-coding small RNAs that negatively regulate gene expression and regulate protein synthesis rate by changing the stability of targeted mRNA. This article reviews the latest research progress on the involvement of miRNAs in the progression of atherosclerotic plaques, the molecular mechanism of cardiac injury and subsequent remodeling during infarction, as well as the results of clinical studies, and puts forward the problems and limitations of targeted miRNAs in the treatment of cardiovascular diseases such as myocardial infarction and ventricular remodeling.
