The adult heart has been considered as an organ with limited regenerating capability due to mature cardiomyocytes exit the cell cycle and stop proliferating. It has been reported that miR-17-92 cluster plays a key role in cardiomyocyte proliferation. According to the seed sequence, miR-17-92 cluster includes miR-18, miR-19, miR-20 and miR-92 families. Here, we show that intra-cardiac injection of miR-19 mimic into adult mouse hearts protects heart from myocardial infarction injury with reduced apoptosis, enhanced cardiomyocyte proliferation and cardiac regeneration. We performed the RNA-seq profiling in both injection of control mimic and miR-19 mimic post myocardial infarction. The transcriptome analysis indicates that genes related to immune response and cardiac remodeling were repressed by miR-19 in infarcted hearts.
