Calreticulin is a Ca(2+)-binding molecular chaperone of the lumen of the endoplasmic reticulum. Calreticulin has been shown to be essential for cardiac and neural development in mice, but the mechanism by which it functions in cell differentiation is not fully understood. To examine the role of calreticulin in cardiac differentiation, the calreticulin gene was introduced into rat cardiomyoblast...
Studies using pharmacological and genetic approaches have shown that increased activity/expression of the Na+/H+ exchanger isoform 1 (NHE1) play a critical role in the pathogenesis of cardiac hypertrophy. Despite the importance of NHE1 in cardiac hypertrophy, severe cerebrovascular side effects were associated with the use of NHE1 inhibitors when administered to patients with myocardial infarct...
The acetylation status of core histones in cardiomyocytes has been linked to the development of cardiac hypertrophy and heart failure. Little is known, however, of the genes affected by abnormal histone acetylation in such pathological conditions. We recently developed a genome-wide screening method, differential chromatin scanning (DCS), to isolate genomic fragments associated with histones su...
The role of peroxisome proliferator-activated receptor (PPAR )-stimulated phospholipase A 2 (PLA 2 ) in cardiac mitochondrial cardiolipin (CL) biosynthesis was examined in both in vivo and in vitro models. Treatment of rat heart H9c2 cells with clofibrate increased the expression and activity of 14 kDa PLA 2 but did not affect the pool size of CL. Clofibrate treatment stimulated de novo CL bios...
The Ubiquitin proteasome system (UPS) plays roles in protein degradation, cell cycle control, and growth and inflammatory cell signaling. Dysfunction of UPS in cardiac diseases has been seen in many studies. Cholesterol acts as an inducer of cardiac hypertrophy. In this study, the effect of proteasome inhibitors on the cholesterol-induced hypertrophic growth in H9c2 cells is examined in order t...
Lack of pharmacological strategies in clinics restricts the patient prognosis with myocardial ischemia/reperfusion (I/R) injury. The aim of this study was to evaluate the cardioprotection of combined salvianolic acid B (SalB) and ginsenoside Rg1 (Rg1) against myocardial I/R injury and further investigate the underlying mechanism. I/R injury was induced by coronary artery ligation for Wistar mal...
Hyperglycemia-induced reactive oxygen species (ROS) generation contributes to development of diabetic cardiomyopathy (DCM). This study was designed to determine the effect of an antioxidant butin (BUT) on ischemia/reperfusion-induced myocardial injury in diabetic mice. Myocardial ischemia/reperfusion (MI/R) was induced in C57/BL6J diabetes mice. Infarct size and cardiac function were detected. ...
Ischemic heart disease still remains the most common cause of cardiac death. During ischemia-reperfusion (I/R), reactive oxygen species (ROS) are produced in excess in cardiac tissue, where they induce cell death. Our previous study showed that 9-phenanthrol (9-Phe), a specific inhibitor of the TRPM4 channel, preserves cardiac contractile function and protects the heart from I/R injury-related ...
