Abstract：Objective To investigate the effect of miRNA-1 on the cardiomyocyte apoptosis in rats. Methods MicroRNA-1 mimics was transfected into the cultured H9c2 cell line (miRNA-1 group). Cells transfected with random miR-NA fragment was used as negative control group. The cell apoptosis was evaluated by FCM assay. MTT assay was used to de-tect the cell viability. The expression level of miRNA-1 was detected by real-time PCR. The expression levels of Bcl-2 mRNA and protein were detected by real-time PCR and Western blot assay. Results Compared with normal and negative control groups, the expression level of miRNA-1 was significantly higher in H9c2 cardiomyocytes, the apoptosis rate was in-creased, the cell vitality and Bcl-2 expression level were significantly decreased after transfection of miRNA-1 mimics. Conclusion miRNA-1 mimics can up-regulate miRNA-1 level, inhibit proliferation and induce cardiomyocyte apoptosis.
