DECIPHERING THE ROLE OF FOXP1 IN MAMMARY STEM CELLS AND DEVELOPMENT

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.

Summary
Understanding the factors regulating blood production is critical to understanding how blood cancers occur and for the development of new therapies. Evidence is emerging of a vital role for the evolutionary conserved ‘polarity’ proteins in blood production and leukaemia This project will elucidate the role of the polarity protein, Par3, in normal and malignant blood cells, providing valuable insight into how Par3 regulates blood formation and the onset and severity of leukaemia.
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.
Deciphering The Role Of Scribble In Development And Disease

Summary
Scribble is a protein that controls the orientation and organization of all cells within our body. Mutations in the Scribble gene are found in many cancers and also in some patients with spina bifida, however how these mutations cause these diseases is not understood. Here we propose experiments that can be used to link Scribble mutations to specific cellular functions. This information will help us design new therapies to treat diseases driven by tissue disorganization such as cancer.
Preserving Ovarian Function During Chemotherapy And Old Age

Summary
Chemotherapy treatment and the natural ageing process leads to ovarian failure and infertility. For young cancer survivors, chemotherapy induced infertility is devastating, and like aged women, leads to hormonal changes that lead to osteoporosis, diabetes, obesity, and neurodegeneration. Here, a new class of molecules will be tested for their ability to prevent and reverse infertility folllowing chemotherapy treatment, and in old age. These findings will improve the healthy lifespan of women.
Developing Novel Molecules That Target Hormone Receptors As An Alternative Cancer Therapy

Funding Amount
$459,867.00
Summary
A promising class of cancer drugs target heat shock protein 90 (Hsp90) and prevent Hsp90 from maintaining its ~100 proteins involved in cell growth. However, all current Hsp90 chemotherapeutics non-selectively target proteins maintained by Hsp90, and induce a cell rescue mechanism involving Hsp70. We describe the development of a novel molecule that will selectively control cell growth and prevent cell rescue via a unique Hsp90 regulated mechanism.
Understanding How Defects In Chromosome Structure Can Cause Disease

Funding Amount
$546,557.00
Summary
The correct folding of DNA is critical to a cell's survival. This is orchestrated by a special class of proteins called the condensins. Defects in condensin lead to aberrant chromosome folding and disease. We aim to understand how condensin folds chromosomes and why mutations in condensin are increasingly associated with disease.
A Stem Cell-specific MicroRNA-independent Function Of Drosha

Funding Amount
$637,702.00
Summary
Stem cells are responsible for producing and replenishing the ~200 specialised cell types in our body. Our goal is to understand the molecular switches that control the function of these cells. We recently discovered that the activity of certain genes within stem cells is controlled by degradation. This degradation is absolutely crucial for safeguarding the function of stem cells. This project will investigate how this novel mechanism is controlled within these cells.
Elucidating The Cellular Processes That Are Critical For P53 Mediated Tumour Suppression

Funding Amount
$1,016,108.00
Summary
p53 is a tumour suppressor gene that is mutated in ~50% of human cancers. Mutations in p53 cause development of cancer and render malignant cells resistant to chemotherapy. We have identified genes regulated by p53 that appear critical for its tumour suppressive function. In this project, we will use innovative novel genetic tools to discover the cellular and biochemical functions of these genes. The ultimate goal of our studies is to identify novel targets for anti-cancer therapy.
The C-type Lectin Mincle Exemplifies A New Mode Of Sterile Inflammation In Cardiovascular Disease

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.
