Influence of oscillatory and unidirectional flow environments on the expression of endothelin and nitric oxide synthase in cultured endothelial cells.
In vivo, endothelial cells (ECs) are subjected to a complex mechanical environment composed of shear stress, pressure, and circumferential stretch. The aim of this study was to subject bovine aorticExpand

Nitric oxide synthase expression in endothelial cells exposed to mechanical forces.
Nitric oxide (NO) has been demonstrated to play a central role in vascular biology and pathobiology. The expression of endothelial NO synthase (eNOS) is regulated in part by blood flow-inducedExpand

Endothelin-1 and endothelin-converting enzyme-1 gene regulation by shear stress and flow-induced pressure.
Hemodynamic forces have been shown to modulate the expression of endothelin (ET-1) and endothelin-converting enzyme (ECE-1) in endothelial cells. We have subjected E.A. hy 926 cells in culture toExpand
