Palmitic acid (PA) is known to cause cardiomyocyte dysfunction. Cardiac hypertrophy is one of the important pathological features of PA-induced lipotoxicity, but the mechanism by which PA induces cardiomyocyte hypertrophy is still unclear. Therefore, our study was to test whether necroptosis, a receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3-) dependent programmed necrosis, was inv...
Background and Aims: There has been scant information concerning antihypertrophic effects of vitamin D specifically on its cellular and molecular mechanisms. Sirtuin 1 (SIRT1) is regarded as a key deacetylase enzyme in cardiomyocytes which applies potential cardioprotective effects by functional regulation of different proteins. This study aimed to evaluate the effects of 1, 25-dihydroxyvitamin...
BACKGROUND Ventricular hypertrophy begins as a physiological adaptation to cardiac overload but progresses to a pathological state. We examined whether the extent of hypertrophy influenced the response to exercise in terms of its effects on regional and global ventricular function and transmural myocardial blood flow distribution. METHODS AND RESULTS Left ventricular (LV) hypertrophy was indu...
Pathological cardiac hypertrophy emerges in the mammalian heart during chronically increased workload (eg, arterial hypertension or aortic stenosis). Although it might in the short term help to compensate cardiac function, it predisposes to the development of heart failure in the long term. It is characterized by an increase in cardiomyocyte size and profound changes in gene expression and is a...
Buckwheat rutin has been found to be able to inhibit angiotensin II (AngII) - induced hypertrophy in cultured neonatal rat cardiomyocytes, but the mechanism remains uncertain. In this study, myocardial hypertrophy model was made by adding AngII to the medium of cardiac myocytes of neonatal rats, meanwhile, different concentrations of buckwheat rutin were applied to observe their effects. Intrac...
