The effect of PS-341 on pulmonary vascular remodeling in high blood flow-induced pulmonary hypertension.
The aim of the present study was to investigate the effects of PS-341 on vascular remodeling in an experimental rat model of high blood flow-induced pulmonary arterial hypertension (PAH), as well as to elucidate its mechanisms of action. We established the PAH model by a surgical method that implanted a left-to-right shunt. Three days post-surgery, the animals were randomly assigned to 3 groups...
متن کاملeNOS expression is not altered in pulmonary vascular remodeling due to increased pulmonary blood flow.
Congenital heart lesions resulting in increased pulmonary blood flow are common and if unrepaired often lead to pulmonary hypertension and heart failure. Therefore, we hypothesized that increased pulmonary blood flow without changes in pressure would result in remodeling of the pulmonary arterial wall. Furthermore, because the vasodilator nitric oxide is produced by the lung, is regulated by fl...
متن کاملAdrenomedullin can protect against pulmonary vascular remodeling induced by hypoxia.
BACKGROUND Chronic hypoxia is one of the major causes of pulmonary vascular remodeling associated with stimulating reactive oxygen species (ROS) production. Recent studies have indicated that hypoxia upregulates expression of adrenomedullin (AM), which is not only a potent vasodilator but also an antioxidant. Thus, using heterozygous AM-knockout (AM+/-) mice, we examined whether AM could attenu...
متن کاملUpregulation of collagens detected by gene array in a model of flow-induced pulmonary vascular remodeling.
We recently reported localized increased pulmonary arterial resistance, neointimal lesions, and medial thickening induced by aortopulmonary anastomosis in young pigs. This model was used to investigate changes in expression of genes potentially involved in pulmonary vascular remodeling employing a high throughput Atlas Human Cardiovascular Array carrying approximately 600 cardiovascular-related...
متن کاملVascular structure determines pulmonary blood flow distribution.
Scientific knowledge develops through the evolution of new concepts. This process is usually driven by new methodologies that provide observations not previously available. Understanding of pulmonary blood flow determinants advanced significantly in the 1960s and is now changing rapidly again, because of increased spatial resolution of regional pulmonary blood flow measurements.
