objective(s):anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. we have investigated the adhesion and proliferation properties of h9c2 cardiac myoblasts on anodized treated titanium surface.  materials and methods: surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (sem). control...

Diabetic cardiomyopathy is associated with suppression of cardiac autophagy, and activation of AMP-activated protein kinase (AMPK) restores cardiac autophagy and prevents cardiomyopathy in diabetic mice, albeit by an unknown mechanism. We hypothesized that AMPK-induced autophagy ameliorates diabetic cardiomyopathy by inhibiting cardiomyocyte apoptosis and examined the effects of AMPK on the int...

Eosinophil cationic protein (ECP) is well known as a cationic protein contained in the basic granules of activated eosinophils. Recent studies have reported that ECP exhibits novel activities on various types of cells, including rat neonatal cardiomyocytes. Here we evaluated the effects of ECP on rat cardiac myoblast H9c2 cells. Our results showed that ECP enhanced the survival of the cells, in...

Gallic acid, a type of phenolic acid, has been shown to have beneficial effects in inflammation, vascular calcification, and metabolic diseases. The present study was aimed at determining the effect and regulatory mechanism of gallic acid in cardiac hypertrophy and fibrosis. Cardiac hypertrophy was induced by isoproterenol (ISP) in mice and primary neonatal cardiomyocytes. Gallic acid pretreatm...

Objective: This study aimed to investigate the effect of osmotin on myocardial ischemia/reperfusion (I/R), as well as the underlying mechanisms. Methods:In vitro I/R injury model was established on rat cardiac myoblast H9c2 cells by oxygen and glucose deprivation followed by reperfusion (OGD/R). Cells were administrated with osmotin, and transfected with small interfering RNAs (siRNAs) which sp...

Diabetic cardiomyopathy is related directly to hyperglycemia. Cell death such as apoptosis plays a critical role in cardiac pathogenesis. Whether hyperglycemia induces myocardial apoptosis, leading to diabetic cardiomyopathy, remains unclear. We tested the hypothesis that apoptotic cell death occurs in the diabetic myocardium through mitochondrial cytochrome c-mediated caspase-3 activation path...
