A wide variety of calcium-activated K channels has been described and can be conveniently
separated into three classes based on differences in single-channel conductance, voltage …

Both increases in the basal cytosolic calcium concentration ([Ca2+] cyt) and [Ca2+] cyt
transients play major roles in cell cycle progression, cell proliferation and division. Calcium …

1 In the presence of indomethacin (IM, 10μm) and Nω‐nitro‐L‐arginine (L‐NOARG, 0.3
mM), acetylcholine (ACh) induces an endothelium‐dependent smooth muscle …

We examined the possibility that Ca*+ released from intracellular stores could activate K+
currents underlying the afterhyperpolarization(AHP) in neurons. In neurons of the dorsal …

Many venom toxins interfere with ion channel function. Toxins, as specific, high affinity
ligands, have played an important part in purifying and characterizing many ion channel …

Intracellular Ca2+ concentration ([Ca2+] i) plays a central role in regulating tone and
contractility of smooth muscle cells. In contrast to the “classic” model of electromechanical …

-Z+ examples of the reverse, Ca-induced inhibition of ion channels, have recently been
found. Ca2+-dependent channels help to shape the action potentials of excitable cells as …

To determine whether K ATP channels control liver growth, we used primary rat hepatocytes
and several human cancer cell lines for assays. K ATP channel openers (minoxidil …

1. The pharmacological sensitivities and physiological contributions of two types of Ca2 (+)‐
activated K+ channels (BK and SK) in GH3 cells were examined by the outside‐out, whole …

The patch-clamp technique was used to determine the ionic conductances activated by ATP
in murine colonic smooth muscle cells. Extracellular ATP, UTP, and 2-methylthioadenosine …
