RNA Expression Profiling of Lung Tissue Identifies Mutually Distinct Molecular Signatures in PAH and PH Secondary to IPF

ABSTRACT: Idiopathic pulmonary arterial hypertension (PAH) is a life-threatening condition characterized by pulmonary arteriolar remodeling, and is frequently associated with right heart failure. This study identifies significant novel biological changes in eight genes and several genetic pathways, that were likely to contribute to the pathogenesis of PAH. We also demonstrate that PAH and PH secondary to idiopathic pulmonary fibrosis (IPF) are characterized by distinct gene expression signatures, implying distinct pathophysiological mechanisms.

Identification of Transcriptional markers in Peripheral Blood of Idiopathic PAH Patients

Project description:Pulmonary Arterial Hypertension (PAH) is characterized by progressive increase in pulmonary vascular resistance, right ventricular failure and premature death. Owing to severe complications, lung biopsies cannot be envisioned to characterize the disease. Based on the prominent role of inflammation in PAH development, we used Peripheral Blood Mononuclear Cells (PBMCs) as cell source, and relied on the SOLiD platform of Serial Analysis of Gene Expression (SAGE) for transcriptional profiling

Pharmacological inhibition of G9a ameliorates pulmonary vascular remodeling in PAH

Project description:Background:Pulmonary arterial hypertension (PAH) is a severe condition characterized by progressive vascular remodeling of small pulmonary arteries (PAs) causing sustained elevation of PA pressure, right ventricular failure and death. Similar to cancer cells, PA smooth muscle cells (PASMCs), which play a key role in pulmonary vascular remodeling, have adopted multiple mechanisms to sustain their survival and proliferation in the presence of stress. The histone methyltransferase G9a has been shown to exert oncogenic effects and to serve as a buffer against an exaggerated transcriptional response. Therefore, we hypothesized that G9a up-regulation in PAH plays a pivotal role in pulmonary vascular remodeling by maintaining the abnormal phenotype of PAH-PASMCs. Methods: G9alevels were measured in PAs and isolated PASMCs of PAH patients and animal models. Selective G9a pharmacological inhibitors were used in human PAH-PASMCs and in rodent PAH models (i.e.Fawn-Hooded rats and Sugen/Hypoxia-exposed mice). Results: We present evidence of increased expression of G9a in PASMCs from PAH patients as well as in remodeled PAs from animal models. We found that pharmacological inhibition of G9a activity using BIX01294 and UNC0642significantly reduces the prosurvival and proproliferative potentials of cultured PAH-PASMCs. Using RNA sequencing, further exploration revealed that G9a promotes extracellular matrix production and affords protection against the negative effects of an overactive stress response. Finally, we found that therapeutic treatment with BIX01294 reduced pulmonary vascular remodeling and lowered mean PA pressure in Fawn-Hooded rats. Treatment of Sugen/hypoxia-challenged mice with BIX01294 also improved pulmonary hemodynamics and right ventricular function. Conclusions:These findings suggest that G9a inhibition may represent a new therapeutic approach in PAH.

PAH sequencing study

Project description:The Cohort study of idiopathic and heritable PAH is an observational, prospective and longitudinal study of patients with idiopathic and heritable PAH. Follow-up information is collected as a part of routine clinical care every six months. The study allows recruitment of both incident and prevalent cases. Patients consented to the study agreed to have blood taken for next-generation sequencing and other omics studies.

Epigenome-wide profiling uncovers novel pathway networks in human pulmonary arterial hypertension [pul28]

Project description:Pulmonary arterial hypertension (PAH) is a progressive pulmonary vascular disease that culminates in right heart failure. Vascular pathology in PH is characterized by pulmonary vasoconstriction and progressive vascular remodeling processes that affects all layers of the vascular wall (intima, media and adventitia). Our objective was to profile and analyze the differential gene expression signatures between the cells isolated from normal and idiopathic PAH patients. We generated vascular cell-specific transcriptome profiles from the adventitial fibroblasts (PAAF) isolated ex vivo from the dissected human pulmonary arteries of normal donor and PAH lungs using paired-end RNA-sequencing.
