Pulmonary Vascular Distensibility and Early Pulmonary Vascular Remodeling in Pulmonary Hypertension

BACKGROUND: Exercise stress testing of the pulmonary circulation may uncover decreased pulmonary vascular (PV) distensibility as a cause of impaired aerobic exercise capacity and right ventricular (RV)-pulmonary arterial (PA) uncoupling. As such, it …

NEDD9 Targets COL3A1 to Promote Endothelial Fibrosis and Pulmonary Arterial Hypertension

Germline mutations involving small mothers against decapentaplegic-transforming growth factor-beta (SMAD-TGF-beta) signaling are an important but rare cause of pulmonary arterial hypertension (PAH), which is a disease characterized, in part, by …

Network Analysis to Risk Stratify Patients With Exercise Intolerance

RATIONALE: Current methods assessing clinical risk because of exercise intolerance in patients with cardiopulmonary disease rely on a small subset of traditional variables. Alternative strategies incorporating the spectrum of factors underlying …

The Long Noncoding RNA LnRPT Puts the Brakes on Pulmonary Artery Smooth Muscle Cell Proliferation

Vascular Stiffness Mechanoactivates YAP/TAZ-Dependent Glutaminolysis to Drive Pulmonary Hypertension

Dysregulation of vascular stiffness and cellular metabolism occurs early in pulmonary hypertension (PH). However, the mechanisms by which biophysical properties of the vascular extracellular matrix (ECM) relate to metabolic processes important in PH …

Upregulation of Steroidogenic Acute Regulatory Protein by Hypoxia Stimulates Aldosterone Synthesis in Pulmonary Artery Endothelial Cells to Promote Pulmonary Vascular Fibrosis

BACKGROUND: The molecular mechanism(s) regulating hypoxia-induced vascular fibrosis are unresolved. Hyperaldosteronism correlates positively with vascular remodeling in pulmonary arterial hypertension, suggesting that aldosterone may contribute to …
