Summary
Wnt proteins are a family of signaling molecules that are critical for the function of normal and cancerous epithelial cells in the gut. However, the cell surface receptor that transmits Wnt signals is not known. Our research strongly implicates one Wnt receptor (FZD7). Here we test this using innovative mouse and cell line models. We wish to understand how Wnt-driven processes are activated. This knowledge will lead to novel avenues to block aberrant activation of Wnt signalling in cancer cells
Barrett's oesophagus (BO) is a condition that arises in some patients with chronic reflux (heartburn) and increases the risk of developing cancer of the oesophagus. However, the exact mechanisms involved in its development are unknown. This project aims to investigate how a protein called sonic hedgehog might be involved using novel cell culturing techniques that allow us to model the growth of oesophageal tissue in the laboratory. This could lead to development of new therapies for treating BO.
The Mechanisms Of Epithelial Cell Survival That Govern Thymus Function

Summary
The thymus is an organ dedicated to the production of crucial immune cells, called T lymphocytes. Cancer treatments, such as radiation or chemotherapy, destroy thymic function and impair immune recovery in patients. We aim to uncover molecular processes that govern the life and death decisions of cells in the thymus. Our goal is to then use this information to develop treatments to protect this critical organ from damage and improve immune recovery following radiation or chemotherapy.
Genetic Programs Orchestrated By AP-1 Transcription Factors In Colorectal Cancer Progression

Summary
Colorectal cancer (CRC) is the third most common cancer worldwide. About half of all patients diagnosed with the disease die as a result of its spread in the body. This project will investigate the role that a specific DNA-binding protein plays in orchestrating gene expression programs required for CRCs to spread. The research will provide new insights into underlying mechanisms of CRC progression as well as identify new therapeutic targets for aggressive forms of the disease.
Mechanistic Basis Of AP-1-regulated Gene Expression During Colorectal Cancer Progression

Funding Amount
$597,802.00
Summary
The spread of colorectal cancers in the body poses a major clinical problem for which current treatment options are inadequate. This project aims to unravel how a specific DNA-binding protein regulates the expression of genes involved in the spread of these cancers. The research is expected to provide a better mechanistic understanding of how disease progression occurs and to identify novel strategies to treat aggressive tumours.
Immune Modulatory Effects Of Vaginal Microbiota Metabolites And HIV Susceptibility

Summary
This study will advance knowledge on how acid molecules produced by beneficial and harmful bacteria are able to promote or impede HIV infection of the female genital mucosa through their effects on the barrier and immune function of cells that line the vagina and cervix. The results of this study are anticipated to augment the efficacy of topical HIV prevention strategies and lead to the development of safe vaginal hygiene products that help protect against other sexually transmitted infections.
Advancement Of A Personalised Approach To Minimising Infective Complications In Cancer Care

Funding Amount
$265,138.00
Summary
Managing infections in patients with cancer have become more difficult and unpredictable because of new generation cancer therapies. Measuring the response of the immune system (immune profiling) will allow us to predict which patients will develop infection so that action such as vaccination can be taken to reduce their risk. This program will refine immune profiling to personalise infection care for cancer patients and to introduce it into hospital practice.
Signaling Pathways To Enhance Potency Of AMPK-targeting Drugs

Summary
Sedentary lifestyles and consumption of high energy foods has led to epidemics of obesity-related metabolic diseases that place enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK) which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Our goal is to improve AMPK drug potency by identifying novel processes that sensitize AMPK to drugs.
UTILITY OF NOVEL BIOMARKERS IN THE PREDICTION OF MAJOR COMPLICATIONS OF TYPE II DIABETES MELLITUS

Funding Amount

Summary
Diabetes is increasingly common. It can cause a variety of complications, the most serious being heart and kidney disease. The reasons why some patients develop such complications are not fully understood so it is difficult to predict who will be affected. The current project will use samples from a large international study of patients with diabetes to assess whether levels of specific markers in the blood help to predict major complications and clarify why they occur.
Effects Of Replacement And Withdrawal Of Testosterone In Human Males On Muscle, Bone And Fat

Summary
Male sex hormone or androgen deficiency (AD) is a common, but under-diagnosed condition. AD decreases well being and contributes to muscle weakness, bone fragility and weight gain. Cutting edge technology will be used to help explain how AD may relate to these negative effects, particularly on muscle function. Given the importance of aging, frailty, osteoporosis and obesity, understanding the role of hormones in these conditions may have major implications for prevention and treatment.
