Rapid detection of rare-event cells by strong UP-conversion
encoded nano-radiators (SUPER Dots): finding a needle in a haystack. Current diagnostic tests are not sensitive enough to detect cancer in its very early stages or early recurrence following treatment. The new technologies developed by this project will be able to find single cancer cells in blood and urine samples heralding a new era in medical diagnostics.

Summary
Structural Analysis of Biomolecular Complexes at Membrane Interfaces Important to Health and Disease. This project will study structural aspects of key biomolecular complexes at membrane interfaces that are involved with apoptosis (programmed cell death). Malfunctions in apoptosis have been implicated in many aliments including age-related diseases and cancers. Understanding of the molecular and structural aspects of key complexes can pave the way to novel therapies.

This project will study structural aspects of key biomolecular complexes at membrane interfaces that are involved with apoptosis (programmed cell death). Malfunctions in apoptosis have been implicated in many aliments including age-related diseases and cancers. Understanding of the molecular and structural aspects of key complexes can pave the way to novel therapies. The approach that will be used is to design new biomimetic outer mitochondrial membranes and use these to study the structure and binding of proteins involved with apoptosis. By studying simple models of complex systems, this project promises to yield detailed information on important biomolecular complexes where structural detail is currently lacking. Read moreRead less
Proteomic study of urine to discover novel biomarkers for human prostate cancer. The purpose of this project is to identify novel markers in the urine of patients with prostate cancer. These biomarkers may ultimately prove useful in the development of novel diagnostic tools for the management of this disease.
Proteomic study of tears to discover novel biomarkers for human breast cancer. The purpose of this project is to identify novel markers in the tears of patients with breast cancer. The results from this study may improve the prognosis of breast cancer patients.
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.

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.
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.
Engineered Hydroxamic Acids for Zirconium-89 Positron Emission Tomography (PET) Imaging of Prostate Cancer. Positron emission tomography (PET) using a zirconium-89-ligand complex bound to a prostate-specific membrane antigen is used to detect and monitor prostate cancer. The hydroxamic acid-based ligand bound to zirconium has a high affinity towards iron, which can cause metal exchange in vivo and loss of radiotracer. The project will prepare new ligands with a higher specificity towards zirconi ....Engineered Hydroxamic Acids for Zirconium-89 Positron Emission Tomography (PET) Imaging of Prostate Cancer. Positron emission tomography (PET) using a zirconium-89-ligand complex bound to a prostate-specific membrane antigen is used to detect and monitor prostate cancer. The hydroxamic acid-based ligand bound to zirconium has a high affinity towards iron, which can cause metal exchange in vivo and loss of radiotracer. The project will prepare new ligands with a higher specificity towards zirconium over iron, and measure immuno-PET imaging activity. A second series of macrocyclic zirconium-specific ligands will be prepared to establish the relationship between variable water-lipid solubility and pharmacokinetic properties. The results will increase the capability of immuno-PET for prostate cancer detection and improve survival outcomes.Read moreRead less
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.
