miR‐17/20 Controls Prolyl Hydroxylase 2 (PHD2)/Hypoxia‐Inducible Factor 1 (HIF1) to Regulate Pulmonary Artery Smooth Muscle Cell Proliferation

Abstract excerpt

BACKGROUND: Previously we found that smooth muscle cell (SMC)-specific knockout of miR-17~92 attenuates hypoxia-induced pulmonary hypertension. However, the mechanism underlying miR-17~92-mediated pulmonary artery SMC (PASMC) proliferation remains unclear. We sought to investigate whether miR-17~92 regulates hypoxia-inducible factor (HIF) activity and PASMC proliferation via prolyl hydroxylases (PHDs). METHODS...
