Background and purpose: Stonefish (Synanceia genus) are commonly found in shallow waters of the Pacific and Indian Oceans. The venom of stonefish is stored in the dorsal fine spines and contains a proteinaceous toxin, verrucotoxin (VTX). The stings p
Verrucotoxin inhibits KATP channels in cardiac myocytes through a muscarinic M3 receptor-PKC pathway

Verrucotoxin is the major component of venom from the stonefish (Synanceia verrucosa). Stings from the dorsal spines of the stonefish produce intensive pain, convulsions, hypotension, paralysis, respiratory weakness and collapse of the cardiovascular

The effect of mibefradil, known as a T- and L-type Ca(2+) channel antagonist, on the histamine-induced Cl(-) current and Ca(2+) entry was investigated in human aortic endothelial cells by the fluorescence measurement of intracellular Ca(2+) concentra

We examined the effects of quinaprilat, an active metabolite of quinapril (an angiotensin converting enzyme (ACE) inhibitor) on the increase in intracellular concentration of Ca2+ ([Ca2+]i) (Ca2+-overload) induced by lysophosphatidylcholine (LPC) in

The role of adenosine triphosphate (ATP) in the regulation of L-type Ca2+ channel activity was investigated in inside-out patches from guinea-pig ventricular cells, in which the Ca2+ channel activity had been reprimed by application of cytoplasm from

Although Cav1.2 Ca(2+) channels are modulated by reactive oxygen species (ROS), the underlying mechanisms are not fully understood. In this study, we investigated effects of hydrogen peroxide (H2O2) on the Ca(2+) channel using a patch-clamp technique

We investigated the concentration- and Ca(2+)-dependent effects of CaM mutants, CaM(12) and CaM(34), in which Ca(2+)-binding to its N- and C-lobes was eliminated, respectively, on the Ca(V)1.2 Ca(2+) channel by inside-out patch clamp in guinea-pig ca

An improved method for isolating cardiac myocytes is described. This method consists of the initial dispersion of the myocytes with a new type of collagenase and the following treatment of the cells with a non-specific protease. This method gives mor
