(Submitter supplied) Bone morphogenetic proteins (BMP) inhibit proliferation and induce apoptosis in pulmonary artery smooth muscle cells (PASMC) from normal subjects. Dysfunction of BMP signaling due to mutations in and/or downregulation of BMP receptors has been implicated in idiopathic pulmonary arterial hypertension (IPAH). We examined whether BMP differentially regulates gene expression in PASMC from normal subjects and IPAH patients using the Affymetrix microarray analysis. more...

(Submitter supplied) Idiopathic pulmonary arterial hypertension (IPAH) is characterized by medial hypertrophy due to pulmonary arterial smooth muscle cell (paSMC) hyperplasia. Interleukin (IL)-13 is a potent regulator of tissue fibrosis and remodelling, and its effects are dependent on the cell-type specific expression of the IL-13 receptor isotypes IL-4Rα, IL-13Rα1, and IL-13Rα2. In order to identify the possible mechanism how IL-13 can exert its antiproliferative effect on paSMC microarray analysis was performed. more...

(Submitter supplied) Pulmonary arterial hypertension (PAH) is a vascular remodeling disease characterized by enhanced pulmonary artery smooth muscle cell (PASMC) proliferation and suppressed apoptosis. Downregulation of the BMPR2 gene along with activation of the transcription factor NFAT have been implicated in the maintenance of pro-proliferative and anti-apoptotic stages of cells. Since an increasing number of microRNAs have been implicated in the regulation of genes specifically important for cell proliferation and apoptosis, we hypothesized that microRNAs might be associated with these cellular features in the etiology of PAH. more...

(Submitter supplied) It has been reported that repeated intra-tracheal instillation of S. chartarum spores induced significant pulmonary arterial remodeling in mice, which resulted in pathological changes like human pulmonary arterial hypertension (PAH) and elevation right ventricle systolic pressure. Then, we used microarrays to know the complex molecular mechanisms that underlie pathogenesis of PAH.

(Submitter supplied) Idiopathic Pulmonary Arterial Hypertension (IPAH) is a severe human disease, characterized by extensive pulmonary vascular remodeling due to plexiform and obliterative lesions, media hypertrophy, and alterations of adventitia. The objective of the study was to test the hypothesis that microscopic IPAH vascular lesions express unique molecular profiles, which collectively are different from control pulmonary arteries. more...

(Submitter supplied) Despite recent improvements in management of idiopathic pulmonary arterial hypertension, mortality remains high. Understanding the alterations in the transcriptome–phenotype of the key lung cells involved could provide insight into the drivers of pathogenesis. In this study, we examined differential gene expression of cell types implicated in idiopathic pulmonary arterial hypertension from lung explants of patients with idiopathic pulmonary arterial hypertension compared to control lungs. more...
