Affinity for MgADP and force of unbinding from actin of myosin purified from tonic and phasic smooth muscle.
Smooth muscle is unique in its ability to maintain force at low MgATP consumption. This property, called the latch state, is more prominent in tonic than phasic smooth muscle. Studies performed at the muscle strip level have suggested that myosin from tonic muscle has a greater affinity for MgADP and therefore remains attached to actin longer than myosin from phasic muscle, allowing for cross-b...
متن کاملN-acetylcysteine reduces chemokine release via inhibition of p38 MAPK in human airway smooth muscle cells.
Reactive oxygen species are involved in the activation of several mitogen-activated protein kinases (MAPKs), key-players in the production of several cytokines. Therefore the current study investigated whether N-acetylcysteine (NAC), an antioxidative agent, inhibits the interleukin (IL)-1beta-induced expression and production of eotaxin and monocyte chemotactic protein (MCP)-1 in human airway s...
متن کاملIntracellular Ca release in skinned smooth muscle
The release of internal Ca from saponin-treated skinned smooth muscle of guinea pig taenia caecum was studied. The amount of Ca released was estimated by the area under the contraction curve during treatment with 25 mM caffeine in the presence of 0.1 mM EGTA. The magnitude of the caffeine response in skinned muscle, after loading with 10(-6) M Ca for 3 min, was similar to that in the depolarize...
متن کاملCalcium-Induced Calcium Release in Smooth Muscle
Calcium-induced calcium release (CICR) has been observed in cardiac myocytes as elementary calcium release events (calcium sparks) associated with the opening of L-type Ca(2+) channels. In heart cells, a tight coupling between the gating of single L-type Ca(2+) channels and ryanodine receptors (RYRs) underlies calcium release. Here we demonstrate that L-type Ca(2+) channels activate RYRs to pro...
متن کاملStretch-induced Calcium Release in Smooth Muscle
Smooth muscle cells undergo substantial increases in length, passively stretching during increases in intraluminal pressure in vessels and hollow organs. Active contractile responses to counteract increased transmural pressure were first described almost a century ago (Bayliss, 1902) and several mechanisms have been advanced to explain this phenomenon. We report here that elongation of smooth m...
