Melanoma is the 4th most common cancer diagnosed in Australia. Advanced melanoma frequently spreads to other organs and can acquire resistance to anti-melanoma treatments, making it fundamentally incurable. I am focused on investigating the mechanisms underlying melanoma disease progression. I will achieve this by comparing the biological nature of melanoma cells at different stages of disease and therapy-resistance to identify new targets for the more effective treatment of patients with melano ....Melanoma is the 4th most common cancer diagnosed in Australia.

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.
Dual Targeting Of The Androgen Receptor For Effective And Durable Control Of Lethal Prostate Cancer

Summary
Preventing binding of androgens to the androgen receptor is the mainstay treatment for advanced prostate cancer, but resistance inevitably develops and the disease becomes lethal. We will develop a new drug that targets a part of the androgen receptor unrelated to its androgen binding function to overcome resistance to current therapy. As this drug will be effective in all stages of prostate cancer, it has high potential to improve survival outcomes for men with prostate cancer.
SFRP4 As A Novel Diagnostic And Therapeutic Target For Gastric Cancer

Summary
Gastric cancer is a common cancer with poor survival, but is and potentially curable when diagnosed at an early stage. However currently there are no non-invasive markers for the early detection of gastric cancer, and treatments for advanced cancer are limited. Secreted frizzled related protein 4 (SFRP4) is a protein that is thought to play a role in invasion of gastric cancer. This study will investigate the utility SFRP4 as a diagnostic test and possible therapeutic for gastric cancer.
Development Of Anti-tropomyosin Drugs For The Treatment Of Melanoma

Summary
Australia has the highest incidence of melanoma worldwide. There is a clear need to develop new strategies as melanoma is unresponsive to current treatment regimes. We have developed a compound, TR100, which targets a specific component of the cytoskeleton of melanoma tumour cells. Disruption of this cytoskeleton leads to decreased tumour cell growth and survival. Understanding the mechanism by which TR100 causes cell death is important if this novel anti-cancer compound is to be used in the cli ....Australia has the highest incidence of melanoma worldwide.

Real-time Imaging Of Cell Cycle Progression In Melanoma

Summary
Melanoma is the most aggressive skin cancer and is highly therapy resistant, reasons of which are poorly understood. Here we hypothesise that differences in the growth capacity of melanoma cells in different tumour regions contribute to therapy resistance. We will use a novel microscopic system that allows us to visualise division of individual melanoma cells in intact tumours in real time. Using this system, we will test the effects of targeted therapies on melanoma cell growth and survival.
The Fellowship would support Professor Bowtell, one of the world’s leading ovarian cancer researchers. His work focuses on clinical problems of chemotherapy resistance and the development of new therapeutic approaches. His studies are underpinned by the Australian Ovarian Cancer Study (AOCS), one of the world’s most sophisticated clinical cohort studies of ovarian cancer, with over 3000 Australian women enrolled.
Apoptosis And Stem/Progenitor Cells In The Development And Treatment Of Cancer

Summary
To improve cancer therapy, we are studying two cancer hallmarks. The first is excessive cell survival. To combat this, we are developing drugs with commercial partners that directly activate the cell's death machinery. The second hallmark is inexorable proliferation, akin to that of stem cells, which can generate entire tissues, as we showed for the breast. ‘Rogue’ stem-like cells may initiate certain cancers. We hope to advance cancer therapy by identifying such cells and drugs that kill them.
Regulation Of ERK Driven Cell Proliferation By The Actin Cytoskeleton

Funding Amount
$920,972.00
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.
Novel Inhibition Of Cancer Cell Growth In Gastrointestinal Cancer

Funding Amount
$47,474.00
Summary
This research project will focus on new treatment targets for gastrointestinal malignancies, focusing on the mTOR pathway which is important in driving cancer cell growth. The mTOR inhibitor drug Everolimus will be used in colon and biliary tract cancers to look for novel biomarkers of response and resistance to treatment, using cancer cell lines and correlative analysis with data obtained from patients' tumour samples and clinical assessment in current trials.
