Summary
We have discovered that mutations in the transcription factor GATA2 result in human primary lymphedema, a debilitating disorder resulting from the failure of lymphatic vessels to return tissue fluid to the bloodstream. The goal of this application is to define the role of GATA2 in lymphatic vessels, in order to understand how GATA2 mutations cause lymphedema. Ultimately, we aim to identify targets to which desperately needed therapeutics for the treatment of lymphedema could be generated.
Roles Of The EMT Transcription Factors In Epigenetic Remodelling And Myeloid Cell Transformation.

Summary
This project is based upon our novel discoveries that identified ZEB2 and SNAI1 as novel genes involved in the development of aggressive forms of blood cancer. During the course of this proposal we will find new drug targets and new drug treatment options using existing drugs that will specifically target cancer initiating cells in order to kill aggressive forms of blood cancers that are currently refractory to treatment.

Summary
This project aims to unravel how one of the most frequently deregulated molecular pathways in colorectal cancer controls the expression of genes required for these tumours to grow and spread. We expect this work to uncover novel therapeutic targets to effectively inactivate this pathway and biomarkers to select patients most likely to benefit from existing therapies.
Deciphering The Transcriptional Program That Instructs Lymphatic Endothelial Cell Fate.

Summary
Lymphatic vessels are essential to maintain fluid balance in most tissues of the human body. Further the lymphatic vasculature plays a central role during cancer and contributes to tumour metastasis. Despite this integral function in health and disease little is known about the molecular programs that coordinate gene expression to build a functional vasculature. This research project will address this gap in our knowledge and will open up new therapeutic avenues for lymphatic vascular disorders
Molecular Basis For Stress-induced Gene Regulation—a Model System To Understand Transcriptional Deregulation In Cancer And Neurological Disease

Funding Amount
$384,076.00
Summary
Deregulated gene transcription plays a critical role in cancer formation. It is therefore important to understand the molecular basis of gene transcription and how tumour cells hijack the process. In this Project, we will study the molecular basis of stress-inducible gene expression. This is particularly important for understanding the molecular basis of cancer as stress-inducible genes are activated by transcription factors implicated in breast, colon, lung, and prostate cancers.

Summary
Approximately 70% of infant death is associated with premature birth. Preterm birth occurs in 6-10% of pregnancies, and there has been no reduction in the rates of premature birth in the last 30 years. This is largely because we remain ignorant of how normal and abnormal birth is controlled. Understanding the physiology of human pregnancy is a critical step in the development of ways to detect and prevent preterm birth. Our group has demonstrated a link between production of a hormone (corticotr ....Approximately 70% of infant death is associated with premature birth. Preterm birth occurs in 6-10% of pregnancies, and there has been no reduction in the rates of premature birth in the last 30 years. This is largely because we remain ignorant of how normal and abnormal birth is controlled. Understanding the physiology of human pregnancy is a critical step in the development of ways to detect and prevent preterm birth. Our group has demonstrated a link between production of a hormone (corticotrophin releasing hormone, CRH) in the placenta and the length of time the baby is carried in the mother. In women who will deliver prematurely a rise in CRH occurs earlier in the pregnancy and more rapidly, while in women who deliver late the rise occurs more slowly. This work has given rise to the concept of a biological clock that determines the length of time the fetus will be carried by the mother before birth, and in which production of CRH in the placenta plays a central role. We have been studying how the CRH gene is controlled in placental cells. We have discovered some regions in the DNA of the CRH gene which have important roles in controlling how much CRH is made by the placenta. The experiments described in this research project will determine the molecular mechanisms that control the production of CRH in the human placenta. This will be done in two ways: (1) by examining the DNA sequences involved in controlling expression of the CRH gene and (2) by identifying the proteins that actually perform the regulating functions that result in either increased or decreased amounts of CRH being produced by the placenta. This important information will help us better understand how normal and abnormal birth is controlled, and from that knowledge new ways to detect and prevent premature birth can be invented.Read moreRead less
Regulation Of Neural Progenitor Cell Self-renewal By The RNA-binding Protein ZFP36L1 During Development And Disease

Funding Amount
$345,401.00
Summary
The timely differentiation of neural stem cells is critical during development, and the unrestrained proliferation of neural stem cells in the adult can lead to deadly brain cancers such as glioma. At present our understanding of the key molecules that regulate neural stem cell behaviour during these processes remains limited. In this proposal we will investigate the molecular determinants underpinning neural stem cell biology, both within the developing brain, and within glioma.
Dual Targeting Of The Androgen Receptor For Effective And Durable Control Of Lethal Prostate Cancer

Funding Amount

Summary
Preventing binding of androgens to the androgen receptor is the mainstay treatment for advanced prostate cancer, but resistance inevitably develops and the disease becomes lethal. We will develop a new drug that targets a part of the androgen receptor unrelated to its androgen binding function to overcome resistance to current therapy. As this drug will be effective in all stages of prostate cancer, it has high potential to improve survival outcomes for men with prostate cancer.
Brain Repair Following Stroke: The Role Of Npas4, A Neural-specific Transcription Factor

Summary
Stroke is the #1 cause of adult disability in Australia and #2 cause of death. About 60,000 Australians suffer a stroke each year while about 250,000 live with the disabilities of stroke, costing over $2B/year. The Queen Elizabeth Hospital and University of Adelaide will study why the Npas4 gene switches on after stroke and the role it plays in brain repair. Future health benefits may be tests to help improve stroke outcome in patients and therapy to decrease loss of brain cells after stroke.

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.
