LncRNA H19 Promotes Angiogenesis in Mouse Pulmonary Artery Endothelial Cells by Regulating the HIF-1α/VEGF Signaling Pathway.

ABSTRACT: Persistent pulmonary hypertension of the newborn (PPHN) is a syndrome of acute respiratory failure characterized by systemic hypoxemia and elevated pulmonary arterial pressure, which leads to pathological changes in pulmonary vascular remodeling and endothelial cell function. Long non-coding RNA (lncRNA) H19 has been shown to be involved in the regulation of arterial endothelial cell function, but its regulatory role in PPHN is not fully understood. In the present study, mouse pulmonary artery endothelial cells (MPAECs) were cultured in a hypoxic conditions. Subsequently, the regulatory function of lncRNA H19 on MPAECs was explored by constructing adenoviruses knocking down and overexpressing lncRNA H19. The results revealed that the hypoxic conditions could induce the proliferation and mi
