AIM: To investigate the effect of micro RNA-214(miR-214) on cardiomyocyte hypertrophy and the expression of the potential target genes. METHODS: A cell model of hypertrophy was established based on angiotensin-Ⅱ(Ang-Ⅱ)-induced neonatal mouse ventricular cardiomyocytes(NMVCs). Dual luciferase reporter assay was performed to verify the interaction between mi R-214 and the 3 'UTR of MEF2 C. The expression of MEF2C and hypertrophy-related genes at m RNA and protein levels was determined by RT-q PCR and Western ...
