Regular exercise can protect the heart against external stimuli, but the mechanism is not well understood. We determined the role of adenosine monophosphate-activated protein kinase (AMPK) in regulating swimming exercise-mediated cardiac protection against β-adrenergic receptor overstimulation with isoproterenol (ISO) in mice. Ten-week-old AMPKα2+/+ and(More)
Cardiac hypertrophy is a key pathological process of many cardiac diseases. However, early detection of cardiac hypertrophy is difficult by the currently used non-invasive method and new approaches are in urgent need for efficient diagnosis of cardiac malfunction. Here we report that speckle tracking-based strain analysis is more sensitive than conventional(More)
AIMS The H19 lncRNA, a highly abundant and conserved imprinted gene, has been implicated in many essential biological processes and diseases. However, the function of H19 in the heart remains unknown. In this study, we investigated the function and underlying mechanism of H19 in regulating cardiomyocyte hypertrophy. METHODS AND RESULTS We first detected(More)
