Endothelial nitric oxide synthase function in pig lung after chronic pulmonary artery obstruction.

Effects of cigarette smoke on endothelial function of pulmonary arteries in the guinea pig

BACKGROUND Cigarette smoking may contribute to pulmonary hypertension in chronic obstructive pulmonary disease by altering the structure and function of pulmonary vessels at early disease stages. The objectives of this study were to evaluate the effects of long-term exposure to cigarette smoke on endothelial function and smooth muscle-cell proliferation in pulmonary arteries of guinea pigs. M...

Association between T-786C polymorphism of endothelial nitric oxide synthase gene and level of the vessel dilation factor in patients with coronary artery disease

Various polymorphisms on endothelial nitric oxide synthase (eNOs) gene cause reduced production of NO, the endothelial relaxing factor, and may accelerate the process of atherosclerosis. The study designed to investigate the frequency of T-786C polymorphism of the eNOs gene in patients suffering from coronary artery disease (CAD) in north-west of Iran. One hundred twenty subjects including 60 p...

Retraction Note: Association between T-786C polymorphism of endothelial nitric oxide synthase gene and level of the vessel dilation factor in patients with coronary artery disease

Increased susceptibility to hypoxic pulmonary hypertension in Bmpr2 mutant mice is associated with endothelial dysfunction in the pulmonary vasculature.

Patients with familial pulmonary arterial hypertension inherit heterozygous mutations of the type 2 bone morphogenetic protein (BMP) receptor BMPR2. To explore the cellular mechanisms of this disease, we evaluated the pulmonary vascular responses to chronic hypoxia in mice carrying heterozygous hypomorphic Bmpr2 mutations (Bmpr2 delta Ex2/+). These mice develop more severe pulmonary hypertensio...

L-Arginine Deficiency in Cystic Fibrosis Lung Disease

Cystic fibrosis affects multiple organs but lung disease remains the major determinant of patient morbidity and mortality. Cystic fibrosis lung disease is characterized by chronic infection and inflammation. The amino acid L-arginine is substrate for both nitric oxide synthases and arginases. The activity of arginase in sputum is increased while the production of nitric oxide is reduced in the ...
