A new view of K+-induced contraction in rat aorta: the role of Ca2+ binding
Abstract
Strong, K+-induced contractions of rat aorta in Ca-free, Mg-free media were not accompanied by increased intracellular calcium concentration, [Ca2+]i, whereas such contractions in the presence of the divalent cations were correlated with rising [Ca2+]i as assessed by fura-2. At the same time, calcium channel blockers, a modulator of Ca2+-binding proteins, and a modulator of actin polymerization, inhibited all types of K+-induced contractions. …
