Research Abstract |
MCT-induced pulmonary arteries demonstrated binding of pimonidazole, a hypoxia detection agent that binds to regions of hypoxia in the region around vascular walls including lung epithelial cells. Indices of the PAH were significantly alleviated in the Hif-1β+/-mice compared to the control as the following data showed ; the weight ratio of right ventricular to left ventricular with septum was significantly decreased ; the number of pulmonary arteries was significantly increased ; indices of the medial thickness was significantly decreased. The number of musculized pulmonary arteries in MCT-treated Hif-1β+/-mice was significantly decreased compared to that of the control mice. In addition, interestingly, the PAH in wild type mice was ameliorated by administration of bosentan, an endothelin receptor blocker, to the same level of that in Hif-1β+/-mice. These results indicate that the development of MCT-induced PAH was mediated by HIF-1βin endothelial cells.
