Summary
Tissues are built by small populations of progenitor cells which divide unequally to generate different cell types. Recent studies suggest defective progenitor cells are founders of some breast cancers and that progenitor-like cancer cells resist therapy to regenerate tumours. We have shown a progenitor division regulator called GPSM2 controls these cells and inhibits breast cancer. Examination of this new anti-tumour pathway promises to identify therapeutic targets for breast cancer recurrence.
Regulation Of Cell Death, Cell Survival And Ubiquitination In Normal Physiology And Disease

Summary
The project will investigate the functions of specific genes and pathways to understand the molecular basis of various diseases. It is based on our data that indicate new roles for (i) cell death in genomic instability in cancer, and (ii) ubiquitination in hypertension, developmental defects, kidney disease, as well as iron homeostasis. The work will lead to new understanding of human disease and discovery of potential new drug targets. It will also provide training of junior scientists.
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.
Molecular Regulation Of Tumourigenesis By The Polarity Determinant Scribble And Associated Proteins

Summary
Cell polarity is the property of cells to be spatially oriented in a tissue or organ. We have shown that Scribble, a key regulator of cell orientation, may keep tumour development in check. In this proposal, we will examine how disruption of Scribble promotes breast cancer using a combination of tissue culture studies and a newly established mouse model. Understanding how this new pathway can regulate breast tumour development may provide novel targets for therapeutic intervention in cancer.

Summary
I am a cellular and molecular biologist with extensive training in a number of biomedical research areas. For over 20 years I have used my training and skills to understand the normal functioning of the body and what molecular and cellular changes underlie various diseases. This fellowship will allow me to continue the groundbreaking work we have been doing to explore the function of several proteins in diseases such as cancer, hypertension, lung inflammation and anaemia.

Summary
The majority of tumor death occurs due to tumor metastasis. Both tumor growth and tumor spread require angiogenesis, which is thought to be driven by tumor but originated from host endothelial cells. Could tumor cells behave and function like endothelial cells? This application aims to detect the transition of adult epithelial cells to endothelial cells through a transient mesenchymal state. Our studies should reveal both the molecular and cellular causes of vasculogenic mimicry, thus establishi ....The majority of tumor death occurs due to tumor metastasis. Both tumor growth and tumor spread require angiogenesis, which is thought to be driven by tumor but originated from host endothelial cells. Could tumor cells behave and function like endothelial cells? This application aims to detect the transition of adult epithelial cells to endothelial cells through a transient mesenchymal state. Our studies should reveal both the molecular and cellular causes of vasculogenic mimicry, thus establishing a new paradigm in understanding tumor growth and metastasis. Such novel molecular understanding will open up new anti-tumor therapeutic opportunities.Read moreRead less
Promoting Intestinal Stem-cell Mediated Regeneration Following Damage: A Critical Role For Neuregulin 1

Funding Amount
$648,447.00
Summary
Diseases, infections and pathologies are common clinical problems of the intestine in humans that can lead to loss of intestinal tissue. Individuals with these conditions can experience nutritional problems and severe cases result in death. Promoting regeneration of the damaged tissue is critical to re-establish intestinal function. In this study, we will examine the regenerative potential of a growth factor called Neuregulin1 in the intestine with the aim of facilitating tissue regeneration.

Skeletal diseases associated with excessive bone loss and skeletal fragility, such as osteoporosis, affect 2.2 million Australians and cost our health system approximately $7.4 billion per annum. Studies from our laboratory suggest a critical role for the mTOR signalling pathway in bone development. Using transgenic animals and state-of-the-art techniques, we will investigate the role of mTOR in pre- and post-natal skeletal development. Results from these studies may provide novel approaches to ....Skeletal diseases associated with excessive bone loss and skeletal fragility, such as osteoporosis, affect 2.2 million Australians and cost our health system approximately $7.4 billion per annum.
