I am a cell biologist/geneticist focusing on understanding tumourigenesis. Cancer is a multigenic and complicated disease, involving interactions between the tumour and normal tissue. I use the genetically tractable model organism, the vinegar fly, Drosophila, to model cancer in situ and identify novel genes that drive cancer. My 5 year career plan is to use the Drosophila system to model cooperative tumourigenesis in epithelial and brain tissues and translate this to human cancer.
Fzd receptors are often upregulated in gastric cancer, and recent studies have shown that targeting these receptors has be effective at reducing cancer cell growth in other cancers including prostate and breast. This project will use cutting edge technology to firstly determine the specific requirement for Fzd receptors during gastric cancer and then determine the therapeutic benefit of using an antibody to target these receptors in mouse models and human gastric cancer cells.
Breast cancer is the most frequent malignancy among women, with an estimated 1 million new cases per year worldwide. A family of enzymes known as protein tyrosine kinases (PTKs) are fundamental in the initiation and progression of tumour growth and they are frequently hyperactivated in breast cancer. This proposal will examine whether inactivation of the enzyme known as TCPTP contributes to PTK hyperactivation and tumorigenicity in breast cancer.
Characterisation Of The Tumour Suppressor Function Of Caspase-2

Summary
Aberrant cell death (apoptosis) is associated with many diseases including cancer. Apoptosis is mediated by a group of enzymes called caspases. Recently we have discovered that one of these enzymes, caspase-2, acts as a tumour suppressor. We now wish to validate this finding in several preclinical models of cancer and understand precisely how caspase-2 works to safeguard cells against cancer development. These studies will help better understand cancer and ways to treat it.
Identiification Of Novel Biomarkers And Therapeutic Targets For The Treatment Of Pancreatic Cancer

Funding Amount
$362,463.00
Summary
Pancreatic cancer is a devastating disease with an appalling prognosis - only 6% of patient survive 5 years after diagnosis. The aim of this research is to use new technologies to find out how pancreatic cells become malignant and why the cancerous cells are so drug resistant. The goal is to ideantify cell markers to guide drug treatment design and new targets for antibody therapy. By combining emerging technologies we hope to achieve break-through outcomes in the treatment of pancreatic cancer.
The Role Of Clathrin In The Spindle Assembly Checkpoint And As An Anti-cancer Target

Summary
Cell division produces two daughter cells. Incorrect localisation and modification of proteins that regulate mitosis cause errors that can lead to cancer. As well as using a unique machinery mitosis uses proteins involved in non-cell cycle pathways. This project investigates the role during mitosis of one such protein: clathrin. We will identify lead clathrin inhibitory compounds, pitstops, that have potential anti-cancer properties, ultimately to be used as a chemotherapy agent.
Alpha-actinin-4 As An Oncogenic Driver And Therapeutic Target In Melanoma

Funding Amount

Summary
Despite the recent advances in targeted therapy and immunotherapy, curative treatment of metastatic melanoma remains an unmet health problem. In this project, we will potentially demonstrate that a protein called ACTN4 is abnormally expressed at high levels in melanoma cells and plays an important role for melanoma cell survival and resistance to treatment, and thus identify inhibition of ACTN4, either alone or in combination with other drugs, as a novel approach in the treatment of melanoma.
Targeting Survival Pathways To Overcome The Resistance Of Human Melanoma To Treatment

$332,123.00
Summary
Melanoma is a major Australian health problem. This is believed to be due to resistance of melanoma cells to cell death associated with inappropriate activation of survival signalling pathways. My previous studies have provided a number of insights into resistance mechanisms of melanoma cells to apoptosis. I wish to understand more fully the molecular basis of the survival signalling pathways, and to identify new therapeutic targets for overcoming resistance of melanoma to treatment.
