Hsp60 is an important component of defense mechanisms against diabetic myocardial injury; however, the cause of Hsp60 reduction in the diabetic myocardium remains unknown. After stimulation of cardiomyocytes with high glucose in vivo and in vitro, significant up-regulation of miR-1/miR-206 and post-transcriptional modulation of Hsp 60 were observed. Serum response factor (SRF) and the MEK1/2 pathway were involved in miR-1 and miR-206 expression in cardiomyocytes. miR-1 and miR-206 regulated Hsp60 expression post-transcriptionally and accelerated cardiomyocyte apoptosis through Hsp60. These results revealed that miR-1 and miR-206 regulate Hsp60 expression, contributing to high glucose-mediated apoptosis in cardiomyocytes.
