Summary
In this program, I will enhance our understanding of cancer gene regulation and provide novel avenues for the treatment of aggressive tumours. Using own data and that from collaborators, I will determine patterns of gene regulation in blood cancers and identify markers that predict disease outcome. I aim to understand how gene regulation can transform healthy cells into tumour cells and whether personalised treatment can kill tumour cells more effectively and prevent relapse and metastasis.
We have identified genetic abnormalities in 5% of breast cancers that fall in a novel DNA element called BIME1. This proposal aims to determine whether these genetic abnormalities contribute to breast tumourigenesis and which genes and pathways are affected by these mutations. The outcomes of this proposal may lead to the development of novel therapies for breast cancer or could influence the choice of existing therapies for patients that harbour these genetic abnormalities.

Summary
The current biomarker for prostate cancer, PSA, belongs to a large family of related proteins called KLK enzymes. We have evidence that one of these enzymes, KLK4, regulates many different pathways involved in tumour spreading especially to bones. This project will determine the specific components involved with a view to finding better biomarkers of tumour spread and bone metastasis and designing better treatments for these aspects of the disease.
Mitochondrially targeted anti-cancer drugs modulate the mitochondrial genome. Successful cancer management requires novel therapeutical approaches. This project will test the effect of a new class of compounds that target mitochondria, the powerhouse of the cells, where they suppress expression of mitochondrial genes. By this mechanism, cancers that are resistant to apoptosis induction can be inhibited.
Targeting mitochondria with mitocans to treat cancer: mechanistic aspects. Mitochondria are the power-house of the cell and also the reservoir of proteins causing the demise of cancer cells, therefore suppressing tumour progression. This project proposes a novel way to modify certain compounds, increasing their level in mitochondria in order to maximise their anti-cancer effect.
Modulating Skin Regenerative Responses To Improve Wound Repair And Fight Carcinogenesis

Summary
Skin disorders, such as hard to heal wounds or the most common skin cancers, are a major burden on the national health system. Despite their different nature they employ similar mechanisms of response to injury. In this project we intend to develop a comprehensive understanding of the genetic and molecular mechanisms at play to allow clinical interventions to prevent or to cure these disorders.
The role of human single stranded DNA binding protein 1 in the repair of stalled DNA replication forks. It is vital that human cells protect their genetic code in order to prevent cancer. This project will look at how cells do this, with the aim of finding new ways to protect us from cancer.
Acquisition of the mitochondrial genome restores mitochondrial function. The aim of this project is to show that cancer cells with heavily damaged mitochondrial DNA (mtDNA) can acquire the mitochondrial genome from the host and that this results in the recovery of their mitochondrial function. The project is highly significant, as it aims to show in vivo mitochondrial transfer with functional consequences. The project aims to open a new avenue of research and could result in a shift in our under ....Acquisition of the mitochondrial genome restores mitochondrial function.

The project aims to open a new avenue of research and could result in a shift in our understanding of some features of cellular communication and how cells can overcome unfavourable situations.Read moreRead less
Squamous cell carcinoma of the skin is extremely common in Australia, resulting in disfiguring surgeries and deaths. Although cumulative sun exposure is important, some people are very susceptible, and we do not know why. This project hinges on the notion that skin cancer is a complex (many genes involved). We will utilize novel systems to harness this complexity to understand why some people are resistant and others very susceptible so as to design appropriate control measures and treatments.

High-resolution electron microscopy (EM): Direct electron detection cameras are a recent technological breakthrough delivering one of the greatest single advancements to the field of molecular cryo-EM. The aim of this project is to enable a 'first of a kind' cryo-EM platform in Australia enabling high-throughput atomic resolution protein structure determination. This will be achieved by integrating a state-of-the-art Gatan K2 Summit Direct Electron Detection camera system into the established cryo-EM facility managed by the University of Queensland node of the Australian Microscopy and Microanalysis Facility. This will offer unique and significantly improved capabilities for atomic resolution protein structure analysis, and will support a broad range of projects across the biological sciences.Read moreRead less
