Genomic alterations during the progress of pulmonary hypertension

ABSTRACT: Pulmonary hypertension (PH), a rare disorder is a complication of a number of cardiopulmonary, unrelated systemic diseases, drug toxicity and genetic mutations. Major advances have been made in the field, but the pathogenesis of PH is not yet understood. Several experimental models such as monocrotaline (MCT) and hypoxia have been used to understand the mechanism underlying the pathogenesis of PH. We have recently shown that that the addition of hypoxia to MCT injected rats accelerates the disease process leading to neointima formation. We have profiled the lungs of adult male Sprague-Dawley rats kept for 4 weeks in normal atmospheric conditions or in hypobaric hypoxia (380 mmHg) w/o subcutaneous injection with 40 mg/kg MCT or just saline. While MCT and hypoxia altered expression of few
