EPAS1 (Endothelial PAS Domain Protein 1) Orchestrates Transactivation of Endothelial ICAM1 (Intercellular Adhesion Molecule 1) by Small Nucleolar RNA Host Gene 5 (SNHG5) to Promote Hypoxic Pulmonary Hypertension

Abstract excerpt

EPAS1 (endothelial PAS domain protein 1), as the major effect gene for the adaptation to chronic hypoxia, is required for hypoxic pulmonary hypertension (HPH). Downregulated EPAS1 ameliorates the development of HPH. We confirmed that EPAS1-specific inhibitor PT2385 ameliorated HPH features, as demonstrated by right ventricle hypertrophy, right ventricular systolic pressure, and pulmonary vascular remodeling....
