Summary
The motivation for unveiling the normal hormonal and molecular mechanisms involved in the extraordinary vasodilatation associated with pregnancy is that understanding these fundamental processes may provide novel insights into the pathophysiology of preeclampsia and intrauterine growth restriction, as well as potential therapeutic strategies for not only the treatment of these pregnancy specific conditions but also cardiovascular and renal diseases in non-pregnant women and men.
The Role Of Vitamin D In Placental Development And Pregnancy Success

Summary
Vitamin D deficiency affects about 1 billion people worldwide, including up to 80% of Australians depending on age, skin colour and sun exposure. Vitamin D deficiency has now been associated with a large number of common diseases of aging and with pregnancy complications. This proposal will use human pregnancy serum and placenta, as well as mouse gene knockout models, to determine the hitherto unknown roles of vitamin D in development of the placenta and health of mother and baby.
The placenta is essential for fetal-maternal exchange and healthy pregnancy however the factors that are required for the placenta to form are poorly understood. We will investigate how the placenta develops in mice and which are the most important factors that are required for a health placenta to form.
Understanding The Role Of Endogenous And Pharmacologic Glycosaminoglycans In Preventing Pre-eclampsia

Summary
Pre-eclampsia (PE) is a serious pregnancy complication that affects the well being of the mother and baby. There is no cure for PE except for delivery of the baby. This may result in delivery much earlier than expected causing a very premature baby. This study investigates substances in the placenta that may be responsible for causing PE. If we can understand how these substances cause the problem of PE, we may be able to find better ways of treating or preventing it.
Developing Lung Function Reference Ranges In Aboriginal Australians

Funding Amount
$875,382.00
Summary
Lung function in Aboriginal Australians may be up to 30% lower than that of the Caucasian population. Comparing a patient’s lung function result to normal is critical to help diagnose and manage lung diseases. There are no lung function normal ranges for Aboriginal Australians. Our study will measure lung function in healthy Aboriginal children and adults and develop Aboriginal specific reference values and thus help ensure the highest level of clinical care for Aboriginal patients.
Decidual-trophoblast Interactions Critical For Optimal Pregnancy Outcomes

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.
Intergenerational Transmission Of Gender-specific Metabolic Disease For Offspring Born Small: Maternal, Paternal And Embryonic Roles

$689,050.00
Summary
This proposal addresses the underlying metabolic health consequences of poor embryo and growth of the baby across generations. We will define mechanisms by which a poor functioning placenta during a rat mother’s pregnancy programs her offspring born small to transmit gender-specific diseases to the next generation. We will identify mechanistic pathways involved, specifically the relative contributions of maternal and paternal germ lines and adverse maternal adaptations to pregnancy for females b ....This proposal addresses the underlying metabolic health consequences of poor embryo and growth of the baby across generations.

The Pathogenic Role Of A Placenta-specific Protease In Early-onset Preeclampsia

Funding Amount
$601,950.00
Summary
Preeclampsia (PE) is a life-threatening disorder of pregnancy. If left untreated, PE will lead to maternal as well as fetal death. Unfortunately, the only current effective “cure” for PE is to deliver the baby prematurely. The causes of PE are intrinsically related to the placenta, the organ that connects the fetus to the mother. This project will investigate a unique enzyme that is produced only by the placenta, its contribution to PE and its potential as a target for PE treatment.
Measuring Hypoxia Induced MRNA In Maternal Blood To Monitor Wellbeing Of Growth-restricted Fetuses

Funding Amount

Summary
Severely growth restricted fetuses are at peril of stillbirth from low oxygenation. While ultrasound monitoring improves outcomes, babies are still lost. Better ways to monitor the health the unborn baby are needed. We have recently discovered fetuses’ starved of oxygen leak RNA into mother's blood. Thus, measuring RNA molecules in blood could be used to assess fetal health. We will examine whether measuring mRNA in maternal blood could be used to monitor wellbeing of growth-restricted fetuses.
Working Towards A New Therapy For The Prevention Of Restricted Fetal Growth

Summary
If a baby does not grow properly during pregnancy there can be serious health problems when it is born. We also know that small babies have life long risks of poorer health. We have no effective therapies for improving a baby's growth. This application aims to discover a treatment that can help babies grow. This would be an important advance in improving the health of our future Australians.
