The role of proteasomal proteolysis in the pathogenesis of ischemia-reperfusion is being actively studied. To evaluate the participation of the proteasome in the preconditioning and postconditioning phenomena we used primary culture of neonatal cardiomyocytes. This culture was undergone 30min of anoxia followed by 60min of reoxygenation. Preconditioning was(More)
Investigation of the mechanisms of phenotypic realization of allelic polymorphism of the eNOS gene has shown that the level of eNOS mRNA and activity of this enzyme in platelets depends from genotype. We identified a T(-786)-->C polymorphism in the promoter region, a variable number of tandem repeats (4a/4b) in intron 4 and the G(894)-->T polymorphism in(More)
Preconditioning and postconditioning increased numbers of living cells and decreased that of necrotic, apoptotic and autophagic cells in anoxia-reoxygenation of isolated cardiomyocytes. It was established that proteasome inhibitors prevented the necrotic and apoptotic cell death of cardiomyocytes in anoxia-reoxygenation and in such a way reproduce the(More)
BACKGROUND Recent data suggest that low concentrations of proteasome inhibitors (PIs) are cytoprotective in models of ischemia-reperfusion injury, but the underlying mechanisms of this effect still remain unclear. AIM To investigate the effect of 100 nM of clasto-lactacystin beta-lactone on cell death and gene expression in neonatal rat cardiomyocytes(More)
The cell death and gene expression in neonatal cardiomyocyte cultures were investigated in a late postconditioning model. The primary cultures were subjected to a 30min of anoxia followed by 60min or 24h of reoxygenation. Postconditioning was carried out in three cycles of 1min reoxygenations followed by 1min anoxia, respectively. After 24h of reperfusion(More)
BACKGROUND Different allelic variants of endothelial nitric oxide synthase (eNOS) can have different effects on the development of certain forms of ischemic heart disease, depending on the specific human population. The frequency of the polymorphism T(-786) --> C in the promoter, G(894)-->T in exon 7 and the variable number tandem repeat in intron 4 were(More)
Quercetin, a plant-derived flavonoid, has attracted considerable attention as promising compound for heart disease prevention and therapy. It has been linked to decreased mortality from heart disease and decreased incidence of stroke. Here, we report new data showing the angioprotective properties of quercetin mediated by its effect on proteasomal(More)
Proteasomal and autophagic pathways of protein degradation are two essential, endoplasmic reticulum (ER)-associated proteolytic systems involved in the ER stress response. The functional interaction between them has been shown by proteasome pharmacological inhibition. However, little data have been found concerning autophagy induction using an RNA(More)
