The known action of uridine triphosphate (UTP) to contract some types of vascular smooth muscle, and the present finding that it is more potent than adenosine triphosphate in eliciting an increase in cytosolic Ca2+ concentration in aortic smooth musc

Ca2+-activated K+ channels (PKCa channels) account for the predominant K+ permeability of many types of smooth muscle cells. When activated, they oppose depolarization due to Na+ and Ca2+ channel activity. Several vasodilatory agents that increase in

Precipitation of Ca oxalate in the sarcoplasmic reticulum of chemically skinned rabbit psoas fibers caused an increase in light scattering which was proportional to the amount of Ca accumulated per unit fiber volume. The increase in scattering was us

Charybdotoxin (ChTX), a peptidyl inhibitor of the high conductance Ca2+-activated K+ channel (PK,Ca), has been radiolabeled to high specific activity with 125I, and resulting derivatives have been well separated. The monoiodotyrosine adduct blocks PK

Measurement of changes in optical properties of intact muscle fibers during contraction has proven to be difficult or, in some cases, impossible due to movement of the muscle relative to the incident beam. In this paper we describe a technique for im

Membrane currents in small cells of a smooth muscle cell line (A10) derived from embryonic rat thoracic aorta were monitored by the patch electrode whole-cell voltage clamp technique. Three currents, two divalent cation currents, and a Ca2+-activated
