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.
Alpha-actinin-4 As An Oncogenic Driver And Therapeutic Target In Melanoma

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.
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.

Summary
Mortality in breast cancer rises to 80% in cases where secondary tumors form in other organs. To improve outcome, a better understanding of the processes involved in cancer spread is needed. Normal cells contribute to the growth and spread of a tumour and are a target for therapy. When a protein called caveolin-1 is lost from normal cells in a tumour, the prognosis for the patient is much worse. The aim of this project is to understand how this protein can regulate the spread of breast cancer.
An exciting area of drug discovery involves targeting Hippo pathway proteins, particularly one called YAP, which were discovered by members of our research team and which are highly active in some cancer cells, making them grow and spread. We will test whether YAP is a potential drug target to prevent or treat melanoma, a deadly type of cancer that usually arises in the skin but also internal organs and the eye. If so, we would fast-track these drugs for testing in patients via clinical trials.
Regulation Of ERK Driven Cell Proliferation By The Actin Cytoskeleton

Summary
The cells in your body respond to external signals and control their proliferation by transmitting signals from one part of the cell to another. This has usually been thought to involve the movement of signals through a liquid medium without the involvement of any machinery to control the movement. The project aims to test the role of the architecture of the cells in physically moving a growth signal from one place to another. We think that the architecture involved plays a key role in cancer.
Pyk2: A Central Mediator Of Gonadotropin Action In Ovarian Cancer

Summary
Ovarian cancer generally presents at an advanced stage where 5 yr survival is less than 25%. Elevated levels of specific hormones after menopause may increase the risk of this cancer. We have shown that a protein called Pyk2 is activated in response to these hormones and may have significant roles in ovarian cancer cell migration, invasion and proliferation. This project will investigate the role of this protein, with the goal of improved therapeutics for women with ovarian cancer.
Characterisation Of A Novel Oncogene In Breast Cancer

Summary
Breast cancer affects 1 in 8 women in Australia. Cancer cells are able to spread to other sites in the body by a process known as metastasis which is the leading cause of breast cancer death. We have identified a gene which controls breast cancer metastasis and thereby may affect disease outcome. This grant aims to elucidate the mechanisms by which this gene regulates breast cancer metastasis.
Cellular And Molecular Mechanisms Of Hedgehog Signaling In Breast Cancer

Funding Amount

Summary
Breast cancer cells create the conditions for their own survival by communicating their needs to the healthy cells that surround them. We have previously shown that a molecule known as ‘hedgehog’ transmits biochemical signals between breast cancer cells and healthy cells. When hedgehog is ‘silenced’, tumours shrink and stop their spread. In this application, we will identify the cells receiving the hedgehog signal and identify how they support the growth and spread of breast cancers.
