Summary
For the brain to function correctly its neurons must be connected correctly. This project will use a novel mathematical approach to understand how growing nerve fibres find where to go in the developing brain. In particular we will use both experiments and computational analysis to understand how the shape of the tip of a growing nerve fibre helps the fibre navigate. This may help us understand the biological cause of many different types of mental disorders.
Therapeutic Potential Of Transforming Growth Factor-beta Proteins For The Diagnosis And Treatment Of Female Infertility

Summary
We discovered and manufactured a growth factor produced uniquely by the egg. We named this growth factor cumulin. It is a powerful regulator of ovarian function and egg quality. This project will study the basic mechanisms of how cumulin works in the ovary. We will then develop an assay to measure it as a biomarker of human egg quality and quantity. New approaches in fertility preservation for cancer survivors will be developed using cumulin.
Activation Of GDF9 Regulates Human Folliculogenesis

Funding Amount
$531,690.00
Summary
GDF9 is a key regulator of fertility in female mammals, as it controls the process of folliculogenesis. In this grant, we will demonstrate the importance of GDF9 in human folliculogenesis, determine the mechanisms that activate GDF9 and show why aberrant GDF9 activation leads to ovarian disorders. Collectively, the outcomes of this proposal will increase our understanding of the fundamental mechanisms that regulate ovarian folliculogenesis and provide new avenues to manipulate this process.
Tao Kinase, A New Member Of The Hippo Tumour Suppressor Pathway

Summary
The Hippo pathway is a key regulator of tissue growth. It was first discovered in vinegar flies and plays a similar role in mammals. We aim to define the mechanism by which the Tao kinase controls tissue growth by regulating the Hippo pathway. These studies will be performed in flies and mammalian cell culture. Our studies will shed light on how tissue growth is controlled, and have the potential to inform the way that we treat human cancers and tissue growth disorders.
Improving The Prediction And Detection Of Contributors To Term Stillbirth

Summary
Stillbirths are a global human tragedy, with 1 in 130 of all pregnancies in Australia ending in stillbirth. We propose to use ultrasound and blood markers to improve the detection of babies who are not growing well, a leading risk factor for stillbirth. Sleep position has also been associated with stillbirth, so we will study fetal heart rate responses during an overnight sleep study to see if breathing events overnight may be an important contributor to stillbirth in growth restricted fetuses.
Characterising Signals Important For Lymphangiogenesis During Development And Disease.

Funding Amount
$604,938.00
Summary
Lymphatic vessels are a vital component of the cardiovascular system. Abnormalities in the growth and development of lymphatic vessels are associated with human disorders including cancer, lymphoedema and inflammatory diseases. The focus of this application is to characterise signals that direct the construction of lymphatic vessels, with the aim of identifying targets to which novel therapeutics for the treatment of lymphatic vascular diseases could be generated.
Intergenerational Determinants Of Fetal Growth In Aboriginal Western Australians

Funding Amount
$399,179.00
Summary
We will study birth and disease records over 3 generations of Aboriginal families to investigate how a mother’s birth weight and her diseases in pregnancy influence both her reproductive health and her risk of chronic diseases (eg heart disease and diabetes) later in life. This world-first study will guide effective prevention of chronic disease in Aboriginal Australians; it may suggest that prevention needs to start with grand-mothers rather than in later generations.
This study will follow up a birth cohort for 25 years with the aim of looking at critical periods for bone development including the role of in utero exposures, early infancy, age 8 and age 16.
Contribution Of Systemic Inflammatory Response To Brain Injury In Growth Restricted Newborns

Funding Amount
$363,388.00
Summary
Growth restriction during pregnancy can damage the baby’s brain and result in poor outcomes such as learning and attention difficulties and cerebral palsy. Currently there is no treatment available to prevent brain injury in these babies. This study will explore the role of inflammation and brain injury in the growth restricted baby. We will also examine whether a readily available and safe anti-inflammatory treatment can reduce or prevent brain injury following growth restriction.
Diabetic cardiomyopathy (DiabCM) is common in people with diabetes. It predisposes to heat failure. Its cause remains unclear and there is no specific treatment for DiabCM. Inflammation is a fundamental tissue response to a metabolic insult and it occur in DiabCM. The central hypothesis in this work is that inflammation through myocardial macrophage cells contributes to DiabCM. This hypothesis will be tested in animal models and also in cell culutre studies.
