Highlights • Human failing heart ryanodine receptor 2 (RyR2) Ca2+ release channels display an altered regulation to cytoplasmic Ca2+. • Alterations in failing heart RyR2 function are correlated with higher RyR2 phosphorylation and thiol modificat

Oxytocin is known to play important roles in uterine contractions, mediated at least in part by increasing intracellular Ca2+ concentration ([Ca2+]i), through enhancing extracellular Ca2+ entry and Ca2+ release from the sarcoplasmic reticulum, proces

1. Experimental findings in the past decade have greatly advanced present understanding of electrical/mechanical rhythmicities in smooth muscle, including vasomotion. Lymphatic vessels show strong vasomotor activity and have provided a key experiment

1 Intracellular recordings made in single bundle strips of a visceral smooth muscle revealed rhythmic spontaneous membrane depolarizations termed slow waves (SWs). These exhibited ‘pacemaker’ and ‘regenerative’ components composed of summatio

1. Endothelial control of the rate of constrictions and the underlying pacemaker potentials has been studied in vitro in guinea-pig mesenteric lymphatic vessels. 2. ACh stimulated 60% of intraluminally perfused vessels to slow or abolish lymphatic co

The sigma receptor ligand reduced haloperidol (50 and 100 microM), potently inhibited cell proliferation, and induced apoptosis in WIDr colon and MCF-7 adenocarcinoma cell lines. Apoptosis was confirmed after drug treatment of the cells by the presen

Excitatory junction potentials (EJPs) were examined using intracellular recording techniques in mesenteric arteries isolated from 12- to 15-week-old spontaneously hypertensive (SHR), Wistar Kyoto (WKY) and Sprague Dawley (SD) rats. The amplitudes of
