Regulation of calcium current by intracellular calcium in smooth muscle cells of rabbit portal vein.

Effects of concentrations of intracellular calcium, [Ca2+]i, on the voltage-dependent Ca2+ current (ICa) recorded from dispersed single smooth muscle cells of the rabbit portal vein were studied, using a whole cell voltage clamp method combined with an intracellular perfusion technique. Outward currents were minimized by replacement of Cs+ -rich solution in the pipette and 20 mM tetraethylammon...

Caveolins and intracellular calcium regulation in human airway smooth muscle.

Regulation of intracellular Ca(2+) concentration ([Ca(2+)](i)) is a key factor in airway smooth muscle (ASM) tone. In vascular smooth muscle, specialized membrane microdomains (caveolae) expressing the scaffolding protein caveolin-1 are thought to facilitate cellular signal transduction. In human ASM cells, we tested the hypothesis that caveolae mediate Ca(2+) responses to agonist stimulation. ...

A Study on the Effects of Modulation of Intracellular Calcium on Excisional Wound Healing in Rabbit

An in vitro study on the role of intracellular calcium ions in healing of excisional wound in rabbit was undertaken. We employed two drugs namely, glibenclamide and nitroglycerin that are topically applied in vivo to modulate the activity of intracellular calcium. Our model consisted of a 15 ´ 15 mm excisional wound. Seven groups of New Zealand rabbits were used. The first three groups served a...

Regulation of cytosolic calcium by angiotensins in vascular smooth muscle.

The carboxy terminal homologue of angiotensin II (Ang II), Ang-(3-8) or hexapeptide, was used as a model peptide to examine the types of receptor mechanisms involved in calcium mobilization in cultured vascular smooth muscle cells. Hexapeptide did not produce tachyphylaxis but did produce a sustained increase in intracellular calcium. Differences in the increase in intracellular calcium [( Ca2+...

Pkd2 haploinsufficiency alters intracellular calcium regulation in vascular smooth muscle cells.

Autosomal-dominant polycystic kidney disease is a multiorgan disease and its vascular manifestations are common and life-threatening. Despite this, little is known about their pathogenesis. Somatic mutations to the normal PKD allele in cystic epithelia and cyst development associated with the unstable Pkd2(WS25) allele suggest a two-hit model of cystogenesis. However, it is unclear if this mode...
