Peroxiredoxin-1 regulates lipid peroxidation in corneal endothelial cells

Radiation-induced expression of platelet endothelial cell adhesion molecule-1 in cerebral endothelial cells

Background: Radiation-induced molecular changes on the endothelial surface of brain arteriovenous malformations (AVM) may be used as markers for specific vascular targeting agents. In this study, we examined the level of expression of platelet endothelial cell adhesion molecule-1 (PECAM-1) on brain endothelial cell surface after radiation treatment, with the aim of targeting the radiation-induc...

Laminar shear stress inhibits lipid peroxidation induced by high glucose plus arachidonic acid in endothelial cells.

Elevated blood glucose and free fatty acids induce oxidative stress associated with the incidence of cardiovascular disease. In contrast, laminar shear stress (LSS) plays a critical role in maintaining vascular health. The present study examined the mechanism for the antioxidant effect of LSS attenuating the oxidative stress induced by high glucose (HG) and arachidonic acid (AA) in human umbili...

Lead promotes hydroxyl radical generation and lipid peroxidation in cultured aortic endothelial cells.

Early studies by our group have shown that lead-induced hypertension (HTN) is closely related to enhanced activity of reactive oxygen species (ROS). In addition, we have found indirect evidence that hydroxyl radical may be the most likely culprit in lead-exposed animals. In the present study, rat aortic endothelial cells were incubated in the presence of 0, 0.01, 0.1, 0.5, and 1.0 ppm lead acet...

Role of DDAH-1 in lipid peroxidation product-mediated inhibition of endothelial NO generation.

Altered nitric oxide (NO) biosynthesis is thought to play a role in the initiation and progression of atherosclerosis and may contribute to increased risk seen in other cardiovascular diseases. It is hypothesized that altered NO bioavailability may result from an increase in endogenous NO synthase (NOS) inhibitors, asymmetric dimethly araginine (ADMA), and N(G)-monomethyl arginine, which are no...
