Sarcoplasmic reticulum release channels from frog skeletal muscle display two types of calcium dependence
(1993)
Calcium channels derived from sarcoplasmic reticulum of frog skeletal muscle were fused with planar lipid bilayers. Fractional open times displayed two types of calcium dependence: (i) blockable channels showed a bell-shaped ...
Effect of tachycardia on myocardial sarcoplasmic reticulum and Ca2+ dynamics: a mechanism for preconditioning?
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2003-12)
We have previously demonstrated that brief episodes of tachycardia prior to a prolonged occlusion of a coronary artery, followed by reperfusion, substantially reduce the infarct size. Adenosine receptors and mitochondrial ...
Relaxation evoked by extracellular Ca(2+) in rat aorta is nerve-independent and involves sarcoplasmic reticulum and L-type Ca(2+) channell
(ELSEVIER SCIENCE INC, 2009)
The perivascular nerve network expresses a Ca(2+) receptor that is activated by high extracellular Ca(2+) concentrations and causes vasorelaxation in resistance arteries. We have verified the influence of perivascular nerve ...
Functional antagonism of beta-adrenoceptor subtypes in the catecholamine-induced automatism in rat myocardium

Transient Ca2+ depletion of the sarcoplasmic reticulum at the onset of reperfusion
(Oxford University Press, 2010-03)
AimsMyocardial stunning is a contractile dysfunction that occurs after a brief ischaemic insult. Substantial evidence supports that this dysfunction is triggered by Ca2+ overload during reperfusion. The aim of the present ...
Ca2+/calmodulin kinase II increases ryanodine binding and Ca2+-induced sarcoplasmic reticulum Ca2+ release kinetics during β-adrenergic stimulation
(2007)
We aimed to define the relative contribution of both PKA and Ca2+/calmodulin-dependent protein kinase II (CaMKII) cascades to the phosphorylation of RyR2 and the activity of the channel during β-adrenergic receptor (βAR) ...
