Summary
This proposal seeks to identify the critical maternal and embryonic placental factors that regulate the formation of a healthy placenta and thus a healthy pregnancy and baby. Currently there is no way of identifying whether the placenta is forming adequately. The proposed studies are a necessary first step in identifying therapeutic targets for diseases associated with a poorly formed placenta, such as preeclampsia.
Cell-cell fusion is critical for the development and transport capacity of the placenta during pregnancy. Impairments in this process occur in pregnancy complications such as preeclampsia (PE). We have identified a novel pathway (LY6E) regulating placental cell-cell fusion which is also dysregulated in human pregnancies complicated by PE. In the current proposal we will investigate the mechanisms by which LY6E mediates cell-cell fusion and examine its role in the development of PE.

Summary
Intrauterine growth restriction (IUGR) and preeclampsia (PrE) are life threatening to mother and baby, making the baby susceptible to disease as an adult. One of the major causes of PreE and IUGR is placentation. Placentation is affected by the placental renin-angiotensin system (RAS), which is controlled by microRNAs. We will describe these microRNAs, what controls them; determine their expression and RAS expression in normal pregnancy, IUGR and PrE, thus providing novel biomarkers for their ea ....Intrauterine growth restriction (IUGR) and preeclampsia (PrE) are life threatening to mother and baby, making the baby susceptible to disease as an adult.
