Summary
Infinite growth of cancer cells is a hallmark of cancer. Telomerase is required for cancer cell immortality. Inhibition of telomerase may thus offer an opportunity to stop cancer cells. We have identified an inhibitor of telomerase. This project will study the mechanisms of action of the novel inhibitor, investigating how to control cancer cell immortality as a baseline for more applied anti-cancer therapeutic studies.
One of the hallmarks of cancer cells is their ability to divide and multiply in an uncontrolled manner. Specific proteins that make up the skeleton of cells (cytoskeleton) play an important part in the cell division process and as such make extremely important targets for anticancer therapy. Our research is developing ways to best target cell division proteins so that we can make drug resistant cancer cells sensitive to chemotherapy.
Advanced Anti-cancer Activities With Therapeutic Agents That Induce Tumor Cell Apoptosis And Antitumor Immune Responses.

Summary
The aim is to perform pre-clinical studies to identify new therapies for blood cancers. We will utilise three new anti-cancer agents that kill tumor cells and genetically engineered mice that develop cancer. We will determine if these three new agents kill the mouse tumor cells and activate anti-tumor immunity. The combined effect of killing blood cancer cells using new therapeutics, coupled with enhancing the anti-cancer immune response may hold the key to developing new treatments.

Summary
Leukaemia is the most common type of cancer in children but resistance to therapy continues to be a significant problem. This project will investigate the biology of drug-resistance and relapse using a mouse model that replicates the human disease. We hope to identify novel therapeutic targets that can be used in combination with existing therapies to improve outcomes in this disease. We also hope to identify markers that can be used to screen for patients at increased risk of relapse.

Summary
Multiple myeloma (MM) is an incurable progressive cancer of plasma cells within blood. It is the second most common blood cancer and represents 2% of all cancer-related deaths. Statistics show increasing incidence and decreasing age of onset. The cause and progression of MM is poorly understood and current treatments are frequently followed by relapse. This project will assess exciting new therapies against the survival of MM cells leading to more effective treatments in the future.
I am a cancer cell biologist investigating molecular mechanisms of leukaemia cell resistance to chemotherapeutic drugs, and novel strategies for the management of high risk or relapsed disease. For these purposes I have developed orthotopic xenograft mode

Summary
The ten scientific laboratories in this program have joined forces to investigate two ways in which tumours develop. Both are of particular interest, because they suggest new ways in which cancer might be overcome. Most of our tissues are continually renewed throughout life by production of new cells. Therefore many of the old cells in each tissue must die off to maintain the proper cell numbers. To eliminate cells that are no longer needed or have become damaged, the body has developed a remark ....The ten scientific laboratories in this program have joined forces to investigate two ways in which tumours develop. Both are of particular interest, because they suggest new ways in which cancer might be overcome. Most of our tissues are continually renewed throughout life by production of new cells. Therefore many of the old cells in each tissue must die off to maintain the proper cell numbers. To eliminate cells that are no longer needed or have become damaged, the body has developed a remarkable cell suicide process termed apoptosis. Unfortunately, however, occasionally a random accident to the genes in one of our cells prevents the machinery for apoptosis from being turned on. In that case, the cell will not die when it should and, by continually dividing, it may eventually give rise to a cancer. Since most cancer cells still retain most of the machinery for apoptosis, however, a drug that could switch on this natural cell death machinery would provide a promising new approach to cancer therapy. Identifying and developing such drugs is one major long-term goal of this program. The other focus of our program concerns stem cells. These are rare cells with the remarkable ability to generate an entire tissue. For example, one of our laboratories has identified stem cells that can generate all the cells in the breast. The almost unlimited regenerative capacity of stem cells has a built-in danger. If a stem cell acquires the ability to proliferate excessively, it can go on to form a tumour. Indeed, many cancer researchers now suspect that rare stem cells within a tumour cause its inexorable growth. If tumour growth is maintained by stem cells, it will be essential to develop new forms of therapy that target these rare cancer stem cells rather than merely the bulk of the tumour cells. This is another key long-term goal of our program.Read moreRead less

Summary
Cancer of the colon and rectum is the most common form of cancer in Australia. Over 12,000 people are diagnosed each year with colorectal cancer (CRC) and more than one third of people will die of their disease. CRC is caused by mistakes in production of colon cells. Our research aims to discover new ways to detect CRC, develop smart drugs and nanoparticle delivery systems for destroying all types of CRC cells. We will then test our new anti-cancer drugs in clinical trials with CRC patients.
Investigating Tumour Biology Using Regulated RNAi In Cells And Mice

Summary
Inhibiting gene expression using the recently discovered process known as RNA interference (RNAi) can be used as an experimental tool to analyse specific genes, in cells and genetically engineered animal models of human disease. I propose to use RNAi to mimic human cancer gene mutations in mouse cancer models, and aim to discover novel tumour suppressor genes. A further aim is to validate potential drug targets in cancer by using RNAi to inhibit specific genes in established mouse tumours.
Targeting MYC-driven Cancers By Inhibition Of The MTOR Pathway

Summary
This proposal will evaluate a new strategy for treating cancers associated with the cancer causing gene MYC. Globally there are more than 1 million cases of MYC-associated cancers diagnosed per year. Based on encouraging early results we will test if turning off the proteins associated with mTOR will be an effective strategy for treating MYC cancers using state-of-the-art cancer models and investigate why these cancers respond.
