Mechanisms of newborn pulmonary hypertension caused by chronic intrauterine hypoxia
PROJECT SUMMARY Chronic intrauterine hypoxia is common amongst not only the 140 million people in the world living at high altitudes but also in many complications of pregnancy such as preeclampsia, cigarette smoking, and placental insufficiency. Adaptation of the fetus to chronic hypoxia results in many adverse developmental outcomes, including pulmonary hypertension of the newborn. The BKCa channel is critical to the relaxation of the pulmonary vasculature of the newborn at birth. Recent results from our well-established fetal lamb model of chronic hypoxia during pregnancy points to BKCa channel dysfunction as a causal factor in pulmonary hypertension. The work in this proposal will…
