Summary
Although it is evident that fair skin types are more susceptible to sun damage, the relationship between sun exposure, skin colour and skin cancer formation is less clear. The genes and processes that determine an individual's skin phototype and the mechanisms involved in the tanning response after UV-exposure of the skin are the focus of this investigation. A major regulator of the response to UV radiation in the skin is the melanocortin-1 receptor.

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.
Identifying Cell Type Specific Biomarkers Of Recurrent Oral Squamous Cell Carcinoma And Mapping Cancer-stroma Interactions Using Single Cell Biology And Cell-to-cell Communication Networks

Summary
Cancer is a major cause of death in Australia. Despite advances in our understanding of the mutations that occur and the sets of genes expressed in cancer we have a major gap in our understanding of what is happening within tumours. Using new single cell technology we will generate new molecular portraits of cancers that give us understanding of the sets of genes expressed on individual cancer cells, the normal cells within a tumour and how they interact with cancer cells to form a tumour.
Single Cell Genetic Profiling To Reveal Molecular And Cellular Changes In BRCA Preneoplastic Tissue

Summary
The initial molecular and cellular events that lead to breast cancer in women with BRCA1 or BRCA2 mutations are unknown. We will use state-of-the-art genomic tools (Single Cell RNA-seq and whole genome sequencing) to determine how cancer begins in absence of normal BRCA genes. Single cell genomic profiling of stem and daughter cells from pre-cancerous breast tissue will be used to identify early-indicator molecular changes that could be exploited in the clinic.
Targeting Homeobox Genes In Acute Myeloid Leukaemia

Summary
Acute myeloid leukaemia (AML) is a common blood cancer with dire clinical prognosis due to a lack of targeted molecular therapies. In this proposal we will identify new ways of targeting transcription factor proteins that are overexpressed in AML and promote leukaemia by repressing normal cellular growth controls. This may lead to novel methods to target leukaemic stem cells to specifically eliminate myeloid leukemia
Investigation Of The Molecular Basis Of Human Nevogenesis And Melanoma Initiation

Summary
The number of moles and lifetime exposure to solar UV are the major risk factors in melanoma development. A genetic association between the IRF4 gene and mole number and melanoma susceptibility has been reported. We propose that changes in the function of this gene will impact on the behaviour of melanocytes/melanoma cells, their response to UV radiation and interaction with surrounding cells. Understanding the function of this gene will provide crucial insight into the initiation of melanoma.
Cell survival and death are controlled by two processes known as apoptosis and autophagy. Apoptosis eliminates damaged cells whereas autophagy gets rid of faulty components in the cell. The Bcl-2 proteins regulate both processes. It is well established that dysfunctional Bcl-2 regulation leads to cancer. In this project, we aim to investigate if deregulated Bcl-2 control of autophagy also has a key role in cancer progression and to obtain a molecular picture of how this control is exerted.
Genetic Programs Orchestrated By AP-1 Transcription Factors In Colorectal Cancer Progression

Summary
Colorectal cancer (CRC) is the third most common cancer worldwide. About half of all patients diagnosed with the disease die as a result of its spread in the body. This project will investigate the role that a specific DNA-binding protein plays in orchestrating gene expression programs required for CRCs to spread. The research will provide new insights into underlying mechanisms of CRC progression as well as identify new therapeutic targets for aggressive forms of the disease.
Microtubule Cytoskeleton In Tumourigenesis And Metastasis

Summary
Over one million cases of lung cancer are diagnosed each year worldwide, making this the leading cause of cancer death. Advanced non-small cell lung cancer (NSCLC) accounts for more than 80% of lung cancer cases. We have identified a protein called ?III-tubulin that is often highly expressed in aggressive and drug resistant NSCLC, and is involved in tumour formation. We will examine how ?III-tubulin is working and identify ways to target this protein to stop tumour growth.
