1 Shear stress-induced ATP-mediated endothelial constitutive nitric oxide synthase expression in human lymphatic endothelial cells. Adenosine Triphosphate nitric oxide synthase 3 Homo sapiens
2 Exogenous ATP ranging in concentration from 10(-9) to 10(-6) M produced a significant increase in ecNOS immunohistochemical expression in a dose-dependent manner. Adenosine Triphosphate nitric oxide synthase 3 Homo sapiens
3 The increase in ecNOS expression mediated by 10(-6)M ATP was significantly reduced by 10(-5) M suramin. Adenosine Triphosphate nitric oxide synthase 3 Homo sapiens
4 These findings suggest that shear stress produces a significant release of ATP from LEC, which activates the purinergic P2X/2Y receptor, thereby facilitating ecNOS mRNA and protein expression through inositol 1,4,5-trisphosphate-mediated release of intracellular Ca(2+) ions and the activation of Ca(2+)-activated K(+) channels in LEC. Adenosine Triphosphate nitric oxide synthase 3 Homo sapiens
