We recently reported the existence of a bronchial epithelium-derived relaxing factor (BrEpRF) capable of reducing pulmonary arterial smooth muscle force generation in the newborn rat. We reasoned in this study that BrEpRF has physiological significan

8-Isoprostaglandin F2α (8-iso-PGF2α) is a bioactive lipid peroxidation product that is a vasoconstrictor at high concentrations. Paradoxically, at lower, and possibly physiological, concentrations, it is a pulmonary vascular muscle's relaxant. Its

Neonatal rats exposed to 60% O2 for 14 days develop lung changes compatible with human bronchopulmonary dysplasia and pulmonary hypertension. Our aim was to evaluate and compare the newborn and adult rat pulmonary vascular and airway smooth muscle fo

We hypothesized that reactive O2 species, or their intermediary products, generated during exposure to elevated O2 lead to pathologic endothelin-1 expression in the newborn lung. Endothelin-1 expression and 8-isoprostane content (an in vivo marker of

The aim of the present study was to investigate the roles of Ca2+ and protein tyrosine kinase (PTK) in the insulin action on cell volume in fetal rat (20-day gestational age) type II pneumocytes. Insulin (100 nm) increased cell volume in the presence

Lung epithelial and mesenchymal cells are separated by a basement membrane. At late fetal gestation, this basement membrane in fenestrated, allowing epithelial cytoplasmic extensions to reach in close proximity of the interstitial fibroblast. The enz

There are currently a large number of ongoing gene therapy trials in North America and Europe. These trials have almost exclusively involved patients with inherited lethal disorders or malignancies. Although there are significant ethical and safety i

On a examine les effets d'un agoniste β 2 -adrenergique (agoniste β 2 ) et de l'AMPc sur la concentration de Ca 2+ cytosolique ([Ca 2+ ] c ) et sur le volume cellulaire dans les cellules de l'epithelium pulmonaire distal foetal. Tant la terbutaline

Lung branching morphogenesis depends on mesenchymalepithelial tissue interactions. Keratinocyte growth factor (KGF) has been implicated to be a regulator of these tissue interactions. In the present study, we investigated the role of KGF in early rat
