Summary
This project investigates two of the life-changing cardiovascular events that most commonly impact on Australians today; Heart attack and Stroke. These diseases often leave individuals debilitated with a long recovery period, and for many people the event is fatal. We have shown that blocking the action of an immune component, "Mincle", reduces the inflammation associated with stroke, and improves recovery. This project looks at what Mincle does in brain and heart muscle, and why blocking Mincle ....This project investigates two of the life-changing cardiovascular events that most commonly impact on Australians today; Heart attack and Stroke.

Regulation Of TNF Expression In Inflammation And Cancer

Summary
By studying a spontaneous mutation in mice, we have found an error in the TNF gene (a major factor in many inflammatory diseases) that causes severe arthritis, heart valve disease and gut inflammation. We have also identified new regulators of TNF expression, which might be useful therapeutic targets to limit inflammation. We intend to study the role of these regulators in controlling the expression of TNF, and the link between chronic inflammation and the development of cancer.
Dissecting The Embryonic Blood-endothelial Regulatory Code And Investigating Its Role In Leukaemia

Summary
Cancer initiating cells acquire stem cell characteristics and multiply within a supportive environment that helps maintain and propagate malignant cells. Identifying the normal hierarchy of gene control within blood stem cells and designing therapies that target cancer cells is the ultimate goal of this body of work.
Understanding How RUVBL1 And RUVBL2 Organise Chromosomes And Their Links To Disease

Funding Amount
$605,005.00
Summary
Our proposal will provide a deep mechanistic framework to inform both clinicians in diagnosis and management of RUVBL related diseases and also therapeutically, as industry looks to use these proteins as drug targets. The great excitement of RUVBL in translation has outpaced the gathering of vital knowledge underpinning the function; knowledge this proposal will provide for the first time.
DECIPHERING THE ROLE OF FOXP1 IN MAMMARY STEM CELLS AND DEVELOPMENT

National Health and Medical Research Council
Funding Amount
$569,109.00
Summary
Breast (mammary) epithelial cells undergo major changes across developmental stages, including puberty, pregnancy and lactation. This project will focus on the role of the molecular regulator, Foxp1, and how it influences normal mammary maturation. This work will inform whether Foxp1 is critical for controlling the activation of dormant stem cells and if this pathway can contribute to breast cancer formation when disrupted.
Endocardial sprouting and mechano-signalling in heart trabeculation. This project aims to understand how the ventricles, the pumping chambers of the mammalian heart, form during embryonic life. Critical is the elaboration of trabeculae, myocardial projections that form a sponge-like layer on the inner surface of the chamber wall and which play vital roles in contraction, oxygen and nutrient exchange, conduction and septation. The project expects to develop a deeper understanding of trabeculation ....Endocardial sprouting and mechano-signalling in heart trabeculation.

Critical is the elaboration of trabeculae, myocardial projections that form a sponge-like layer on the inner surface of the chamber wall and which play vital roles in contraction, oxygen and nutrient exchange, conduction and septation. The project expects to develop a deeper understanding of trabeculation using high resolution, single cell methodologies, and to investigate how bio-mechanical forces from contraction or blood flow influence chambers formation.Read moreRead less
Determining recurrence risk in breast cancer is crucial, as more than half of all recurrences occur after 5 years. However, optimal management of breast cancer is hampered by the challenges in finding rational preventative and predictive targets. Our vision is to find targets responsible for progenitor cell expansion, as candidates for prevention, and to find markers of relapse, to predict early versus late responders to therapy.
Understanding The Biological Regulation Of MLKL And Its Role In Necroptotic Cell Death

Summary
Cell death is a normal process that permits the growth and defence of our vital tissues. One kind of cell death, necroptosis, is characterized by the swelling and bursting of cells. When cells ‘explode’ in this uncontrolled way they provoke an inflammatory response. This may be a factor behind illnesses ranging from colitis to cardiovascular disease. Understanding necroptotic cell death may pave the way for new therapies for those that suffer from these devastating conditions.
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 different transcription factors in the Hippo pathway operate to control tissue growth. 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.
