Comprehensive Assessment Of Genetic And Environmental Risk Factors For Melanoma: A Population-based Family Study

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.
Epimutations As Germ-line Defects In Hereditary Cancer Syndromes

Summary
Traditionally familial cancers were thought to be caused and inherited by spelling mistakes within the genetic code of cancer prevention genes. Our group has found that a 'chemical coat' around the MLH1 gene, causing it to be switched off, can also be inherited in some cases of bowel cancer, without any mistakes within the gene's code. We will determine if this 'coat' causes other types of cancer and if this runs in families. We also hope to find out how the coat is formed and may be reversed.
Early diagnosis of melanoma remains extremely challenging. Currently there are no validated blood-based biomarkers for early diagnosis. Therefore, a reliable screening test is an unmet medical need. Autoantibodies are emerging as promising biomarkers for early cancer detection. In a proof of principle experiment we identified five autoantibodies that provide 95% sensitivity / specificity. Now we will confirm and validate our findings and develop a clinical test for melanoma diagnosis.
The Mutagenic Influence Of 5-methylcytosine And Its Relevance For Cancer Treatment

Summary
Over time our cells accumulate damage to their DNA, which introduces mistakes in the genetic code. These mistakes can alter genes that regulate cell growth and survival and, in this way, they begin the process of turning a normal cell into a cancer. This research is investigating the cellular repair mechanisms that safeguard against DNA damage. Manipulating these repair mechanisms may offer a new way to treat cancer, by selectively inducing DNA damage within cancer cells.
Liquid Biopsy For Personalised Monitoring Of Melanoma Patients

Funding Amount
$820,888.00
Summary
Despite the success of recent melanoma treatments, therapies are effective long term in only a proportion of patients. Here we will progress preliminary findings in collaboration with biotechnology and pathology companies to develop highly effective companion biomarkers that will aid treatment decisions throughout disease course. Our team will spearhead translation of these markers into the clinic for routine monitoring of melanoma patients.
Enhancing Aspects Of Time-to-event Analysis Methodology In Randomised Trials

Summary
Time-to-event analysis is a statistical method for examining the occurrence of disease-related events in individuals followed for varying periods of time. The method is widely used in health research. The technicalities of the methods are subtle and by paying careful attention to these this grant will provide extended methods, new software, and apply methods more effectively to gain new insights to disease progress, and to enhance the efficiency of health research.
Role Of Resident Endothelial Progenitor Cells In Melanoma Vascularisation And Progression

Funding Amount

Summary
Melanoma is one of the most frequent cancers in Australia. Its growth depends on the rpoper delivery of nutrients and oxygen through blood vessels. This requires the formation of new blood vessels as the tumour grows. In this project we intend to understand the origin of the blood vessels that form in tumours and identify the stem cells that support them. We will use proof of principle experiments to determine whether removal of these stem cells allows the regression of melanoma tumours.
The Role Of Force-sensing Ion Channels In Melanoma Migration

Funding Amount

Summary
Metastasis of melanoma cells away from the primary tumour site carries a very poor patient prognosis.This research aims to characterise a novel signalling pathway that can regulate the migration (movement) of melanoma cells. This signalling pathway depends on force-sensing platforms that can rapidly convert physical inputs from the environment into an electrical signal within the cell. We are working to understand how these force-sensors function.
Tailoring Targeted Therapy To DNA Repair-defective High-Grade Serous Ovarian Cancer

Funding Amount

Summary
Ovarian cancer is a major cause of cancer death in women because current treatments are inadequate. Half of aggressive ovarian cancers have abnormalities in DNA repair and should be susceptible to new PARP inhibitor therapy, yet not all those respond. By developing a new model of studying human ovarian cancers in mice, we can discover markers to predict which ovarian cancers will respond best to these exciting new treatments.
The Role Of Melanoma Tumour Antigen P97 (Melanotransferrin) In Melanoma Tumourigenesis.

Funding Amount

Summary
The Role of Melanoma Tumour Antigen p97 (Melanotransferrin) in Melanoma Tumourigenesis Melanotransferrin (MTf) is a homologue of the iron transport protein, transferrin, and was one of the first well characterised melanoma tumour antigens. Our published studies have shown that MTf plays an important role in melanoma tumourigenesis in vivo. In this proposal, we will assess if it is associated with melanoma progression in patient samples and examine its role in melanoma growth and metastasis.
