Oxidative stress in cardiomyocytes contributes to decreased SERCA2a activity in rats with metabolic syndrome.
Ca(+) mishandling due to impaired activity of cardiac sarco(endo)plasmic reticulum Ca(2+) ATPase (SERCA2a) has been associated with the development of left ventricular diastolic dysfunction in insulin-resistant cardiomyopathy. However, the molecular causes underlying SERCA2a alterations induced by insulin resistance and related metabolic disorders, such as metabolic syndrome (MetS), are not com...
متن کاملRestoration of contractile function in isolated cardiomyocytes from failing human hearts by gene transfer of SERCA2a.
BACKGROUND Failing human myocardium is characterized by abnormal relaxation, a deficient sarcoplasmic reticulum (SR) Ca(2+) uptake, and a negative frequency response, which have all been related to a deficiency in the SR Ca(2+) ATPase (SERCA2a) pump. METHODS AND RESULTS To test the hypothesis that an increase in SERCA2a could improve contractile function in cardiomyocytes, we overexpressed SE...
متن کاملTSH inhibits SERCA2a and the PKA/PLN pathway in rat cardiomyocytes
Elevated thyroid-stimulating hormone (TSH) levels often accompany impaired LV diastolic function and subtle systolic dysfunction in subclinical hypothyroidism (sHT). These cardiac dysfunctions are characterized by increases in mean aortic acceleration and pre-ejection/ejection time ratios. To explore the mechanism underlying these pathologies, we investigated the effects of TSH on sarcoplasmic ...
متن کاملContractile arrest reveals calcium-dependent stimulation of SERCA2a mRNA expression in cultured ventricular cardiomyocytes.
OBJECTIVE Downregulation of sarco-endoplasmic reticulum calcium ATPase 2a (SERCA2a) expression is a critical marker of pathological myocardial hypertrophy. The effects of calcium-dependent signaling and of contractile activity on the regulation of myocardial SERCA2a expression remain unclear. The present study dissociates effects of calcium-dependent signaling through calcineurin (CN) and calmo...
متن کاملkinetic properties of lactate dehydrogenase extraeted from mouse embryonic stem cell-derived cardiomyocytes and mouse neonatal cardiomyocytes: a comparative study
introduction: lactate dehydrogenase is one of the cardiac enzyme markers, studied in vivo. in the present study, activity and kinetic properties of enzyme extracted from cardiomycytes derived from mouse embyronic stem cell in vitro were compared with enzyme extracted mouse neonatal from cardiomyocytes in vivo. material and methods: mouse embryonic stem cells were cultured and differentiated and...
