Cancer cachexia is a devastating disease characterised by skeletal muscle wasting and weakness. It impairs patient quality of life and accounts for >20% of cancer-related deaths. My work aims to identify factors contributing to the development of cancer cachexia. This insight will then enable me to test potential strategies to prevent the wasting seen in cancer patients to improve their quality of life and to reduce mortality.
mTOR signalling in serous ovarian cancer. Serous ovarian cancer is the most aggressive and lethal gynaecological cancer in Australian women. Activation of Mammalian Target of Rapamycin (mTOR) is frequently observed and associated with poor prognosis in ovarian cancer patients. However, the mechanisms dysregulating mTOR in the pathogenesis of ovarian cancer are unknown. In preliminary studies, deletion of genes regulating mTOR signalling in up to 60 per cent of human serous ovarian cancer patien ....mTOR signalling in serous ovarian cancer. Serous ovarian cancer is the most aggressive and lethal gynaecological cancer in Australian women. Activation of Mammalian Target of Rapamycin (mTOR) is frequently observed and associated with poor prognosis in ovarian cancer patients. However, the mechanisms dysregulating mTOR in the pathogenesis of ovarian cancer are unknown. In preliminary studies, deletion of genes regulating mTOR signalling in up to 60 per cent of human serous ovarian cancer patients was observed. This project will provide mechanistic details of involvement of mTOR signalling in pathogenesis of the serous ovarian carcinoma, and develop a rationale for targeting mTOR pathway in these patients.

Identification of novel therapeutic targets for selectively eliminating cancer stem cells in paediatric leukaemia. Leukaemia is the most common form of cancer in children, and while the majority of children can be cured, those who relapse face a dire prognosis. It is widely believed that leukemic stem cells are responsible for relapse and this project will aim to unravel their underlying biology and identify new targets for therapeutic approaches to the disease.
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.
The critical role of the class III histone deacetylase SIRT2 in stabilizing N-Myc oncoprotein. Cancer is the commonest cause of death from disease in children. Neuroblastoma is the commonest solid tumor in early childhood. This project will investigate the critical roles of SIRT2 protein in increasing the expression of N-Myc oncoprotein and consequently inducing neuroblastoma, and SIRT2 inhibitors as anticancer agents.
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.

Imaging Cell and Tissue Architecture using Confocal and Super-Resolution Microscopy. Imaging cell and tissue architecture using confocal and super-resolution microscopy: This project aims to understand how the architecture of cells and tissues is controlled.

Imaging cell and tissue architecture using confocal and super-resolution microscopy: This project aims to understand how the architecture of cells and tissues is controlled. This is because the organisation of biological space underpins the function of cells, tissues and organisms. This project will test the role of identified parts of cell architecture in regulating specific animal functions/pathologies. It will do this by using new microscope technologies which are at the frontier of visualising cell structure in isolation and in the context of tissue including application to the living animal. The dynamic organisation of structures in cells will be imaged in living tissue. Novel insights into structure/function relationships in the body will impact the health industry and generate opportunities for new diagnostics and therapeutics. Read moreRead less
Molecular hallmarks of androgen receptor targeting in prostate cancer. There is a critical need in oncology drug development for better biomarkers of response to prostate cancer therapies, clinically to assist with treatment decision making, and pre-clinically to facilitate translation of emerging agents into clinical practice. Using a unique explant culture model, this project will identify protein and lipid markers that can be used to accurately and reliably assess response to androgen recepto ....Molecular hallmarks of androgen receptor targeting in prostate cancer. There is a critical need in oncology drug development for better biomarkers of response to prostate cancer therapies, clinically to assist with treatment decision making, and pre-clinically to facilitate translation of emerging agents into clinical practice. Using a unique explant culture model, this project will identify protein and lipid markers that can be used to accurately and reliably assess response to androgen receptor (AR)-targeting therapies in human prostate tumours. The identification and functional assessment of these biomarkers will identify those that can be used as surrogate endpoints in clinical trials, facilitate earlier approval of investigational agents and lead to improved options for therapeutic management of prostate cancer.Read moreRead less
The development of tuneable materials to allow the three-dimensional printing of cells. New low cost three-dimensional (3D) printers and reagents will be developed during this project to allow cancer biologists to print cells and polymers as more realistic 3D tissue models for biological assays. Such technology will be important for performing basic research into cancers as well as for providing better tools for drug testing.
Understanding endocrine tumorigenesis - opportunities for new diagnostics and therapies. This project will generate new knowledge significant for improving cancer diagnosis and designing new therapies for cancer patients as we embrace the personalised medicine era. Specific focus is on endocrine tumours. This research has as its aim improved survival for people diagnosed with cancer.
