There is general agreement now that elevation of intracellular calcium ion concentration [( Ca2+]i) mediates the physiological actions of a number of hormones, neurotransmitters and other pharmacological agents. In smooth muscle one way by which these agents elevate [Ca2+]i and induce contraction in
Ca 2+, calmodulin-dependent myosin light chain phosphorylation is generally considered to be an important regulatory mechanism Of smooth muscle contraction. We investigated the length-dependence of myosin phosphorylation and active stress induced by K + depolarization in arterial smooth muscle by me
When the rabbit thoracic artery was stimulated with submaximal concentrations of agonist [40 mM K+, 30 microM prostaglandin F2 alpha (PGF2 alpha) or 7 microM histamine], about 90% of a maximal contraction occurred. Each agonist induced a rapid development of contraction followed by a sustained respo
