Platelet-activating factor increases endothelial [Ca2+]i and NO production in individually perfused intact microvessels.
We have demonstrated that inhibition of NO synthase (NOS) in endothelial cells by either the NOS inhibitor N(omega)-monomethyl-l-arginine (l-NMMA) or the internalization of caveolin-1 scaffolding domain attenuated platelet-activating factor (PAF)-induced increases in microvessel permeability (Am J Physiol Heart Circ Physiol 286: H195-H201, 2004) indicating the involvement of an NO-dependent sig...
متن کاملInvolvement of Ca2+/calmodulin-dependent protein kinase II in endothelial NO production and endothelium-dependent relaxation.
Nitric oxide (NO) is synthesized from l-arginine by the Ca(2+)/calmodulin-sensitive endothelial NO synthase (NOS) isoform (eNOS). The present study assesses the role of Ca(2+)/calmodulin-dependent protein kinase II (CaMK II) in endothelium-dependent relaxation and NO synthesis. The effects of three CaMK II inhibitors were investigated in endothelium-intact aortic rings of normotensive rats. NO ...
متن کاملDistinct Ca2+ requirement for NO production between proteinase-activated receptor 1 and 4 (PAR1 and PAR4) in vascular endothelial cells.
Proteinase-activated receptors 1 and 4 (PAR(1) and PAR(4)) are the major receptors mediating thrombin-induced NO production in endothelial cells. The intracellular signaling following their activation still remains to be elucidated. The present study provides the first evidence for the distinct Ca(2+) requirement for the NO production between PAR(1) and PAR(4). The activation of PAR(1) by the a...
متن کاملApolipoprotein E enhances endothelial-NO production by modulating caveolin 1 interaction with endothelial NO synthase.
Apolipoprotein E (apoE) is widely expressed in mammalian tissues, and one of the important tissue-specific effects is the atheroprotection ascribed to macrophage-derived apoE in the arterial wall. However, underlying mechanisms are not well understood. In this study, using subcellular fractionation, confocal microscopy, and coimmunoprecipitation, we demonstrated that macrophage-derived apoE is ...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
