Abstract:

The idea for this proposal is that acute high altitude hypoxic exposure early in pregnancy during a critical period of organogenesis may critically reduce O2 transport to the fetus thereby causing Congenital Heart Defects in at-risk pregnancies. The first objective was to use a novel reporter of O2 concentrations, the ODDLuc mouse, to determine the dose-response relationship between hypoxia and reduced O2 delivery to the fetus. The second objective was to develop a novel mouse model of placental insufficiency to examine how maternal-fetal and gene-environment interactions may influence the effect of hypoxia on the developing heart.
