Funding Amount

Summary
Common skin cancers such as basal and squamous cell carcinomas (BCC and SCC) are by far the most frequent cancer worldwide and require over a million interventions per year in Australia. This project will identify the skin cells that are most susceptible to give rise to cancer if excessively exposed to the sun and explores ways to prevent cancer formation. This will inform on new strategies to prevent new skin cancer development.
Muir Torre Syndrome: The Role Of IHC And Genotyping In Sebaceous Neoplasia To Facilitate Prevention Strategies In Colorectal And Endometrial Cancer

Summary
Sebaceous neoplasia (SN), may be an early warning sign for Lynch syndrome (LS), an inherited cancer predisposition caused by mutations in a group of genes. There are high lifetime risks of bowel and uterine cancer, for which there are effective risk management plans if the risk is known. Clinicians are challenged by the role of SN in identifying LS. At present, it is hard to differentiate. We aim to determine features to improve the diagnosis of LS carriers.
Inflammatory skin disorders, such as psoriasis and dermatitis, are responsible for a large burden of human disease and affect people across alldemographics. Knockout (KO) of TNF signalling members in mice is known to induce skin inflammation. This project proposes to use these genetic mouse models to investigate how and why disruption of particular TNF superfamily members leads to disease and potentially identify new targets for treatment.
Comprehensive Assessment Of Genetic And Environmental Risk Factors For Melanoma: A Population-based Family Study

Funding Amount

Summary
Excessive sunlight can cause melanoma, a serious type of skin cancer. However, there are other factors including a person's genetic make-up that are thought to put some people at higher risk. Many 'healthy' people have small changes in their genes that might make them more likely to develop melanoma. We need to know more about these genetic factors. Our study will investigate how particular small genetic changes influence a person's likelihood of developing melanoma.

Interplay Between Metabolic Reprogramming And Oncogenic Signalling In The Cellular Response To Chemotherapy

Funding Amount

Summary
Chemotherapy resistance is a major barrier to the treatment of triple-negative breast cancer (TNBC). We seek to uncover an intimate link between cell metabolism and oncogenic signalling pathways in regulating the cellular response to chemotherapy. Our studies will identify a critical mechanism limiting the therapeutic efficacy of chemotherapy and investigate combination therapy strategies that could improve the treatment of TNBC.
Exploiting And Defining The Immune Regulatory Activities Of BET Bromodomain Inhibitors

Funding Amount
$923,222.00
Summary
Immune-based agents such as “checkpoint inhibitors” have the ability to re-awaken our own immune systems and activate previously dormant anti-tumor responses. We have discovered that small molecule inhibitors of gene regulatory proteins called bromodomain proteins act synergistically with checkpoint inhibitors in mouse cancer models. We will define the molecular and biological events underpinning this novel combination approach and assess the effects of the combination across different tumors.

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

Our preliminary experiments suggest that palmitoylation is crucial for normal skin biology. We will explore its effects on the biology of the proteins which are modified, the cells in which they are found and the tissues in which they reside. Understanding more about these modifications will help us to learn more about the biology of our skin and will help us to understand diseases which affect our largest organ.Read moreRead less
