Nitric oxide augments signaling for contraction in hypoxic pulmonary arterial smooth muscle-Implications for hypoxic pulmonary hypertension

Martha Hinton, James A. Thliveris, Grant M. Hatch, Shyamala DakshinamurtiChildren’s Hospital Research Institute of Manitoba and University of Manitoba.Canada Frontiers in PhysiologyFront Physiol 2023; 14: DOI: 10.3389/fphys.2023.1144574 AbstractIntroduction: Hypoxic persistent pulmonary hypertension in the newborn (PPHN) is usually treated with oxygen and inhaled nitric oxide (NO), both pulmonary arterial relaxants. But treatment failure with NO occurs in
