Potential roles of microRNA-1 and microRNA-133 in cardiovascular disease.

Cardiovascular disease is still the main cause of morbidity and mortality worldwide. Currently, the frontier of research into cardiovascular disease is the field of non-coding RNA. In this review, information was collected on the use of micro-RNAs as non-invasive biomarkers and their role in pathophysiological processes and therapeutic applications. In the case of microRNA-1 and microRNA-133, the roles and regulatory mechanisms of them are reviewed for arrhythmia, myocardial infarction, diabetic cardiomyopathy, myocardial hypertrophy, cardiomyocyte differentiation, and cell reprogramming. It was observed that microRNA-1 and microRNA-133 do not exist independently, but are two co-transcriptional and cooperative regulatory factors. They have diagnostic value as biomarkers, but also have the potential as therapeutic targets such as for antiarrhythmia and cardiac reprogramming.
