Personnel in space, aviation, and terrestrial applications may be exposed to potentially harmful levels of densely ionising radiation. This project will produce improved radiation detectors and computational techniques, addressing needs in the prediction and assessment of equivalent dose in these applications. The "preventative healthcare" priority goal of the National Research Priority "Promoting and Maintaining Good Health" will be addressed, serving to reduce the risk to personnel involved in such activities. This research will also enhance Australia's international reputation in this field, stimulate local expertise, and create a critical mass of researchers in this field. Read moreRead less

This fundamental research will also enhance Australia's international reputation in this field, stimulate local expertise and create a critical mass of researchers working in this sector.Read moreRead less
How the repair of DNA damage is regulated by IGFBP-3, a protein at the crossroads between cell death and survival. This project aims to discover how a protein called IGFBP-3, which is found in essentially all vertebrates, contributes to the repair of damaged DNA, and to the fate of cells after DNA damage. This is important because all cells are thought to suffer DNA damage many times each day, caused by both environmental and internal events. If unrepaired, this damage can permanently affect a c ....How the repair of DNA damage is regulated by IGFBP-3, a protein at the crossroads between cell death and survival. This project aims to discover how a protein called IGFBP-3, which is found in essentially all vertebrates, contributes to the repair of damaged DNA, and to the fate of cells after DNA damage. This is important because all cells are thought to suffer DNA damage many times each day, caused by both environmental and internal events. If unrepaired, this damage can permanently affect a cell’s genetic make-up. If successful, this research will reveal which other proteins IGFBP-3 interacts with, and how it acts at the crossroads between cell survival or death. This information will advance fundamental understanding about important cellular processes and might in future be applied to improving the response of some diseases to treatment.Read moreRead less
The regulation of gene expression by post-translational modification of transcription factors. Different cells in the body express different subsets of our genes, and it is not well understood how cells know which genes to switch on and which to switch off in a given situation. We will investigate the way in which chemical tags are put onto and removed from the molecules that control gene expression in order to direct their function.
The Chemistry and Biochemistry of Chromium: Cancer and Nutrition. Of all of the human carcinogens, chromium(VI) has the highest level of occupational exposure, and is of increasing concern as an environmental carcinogen, as highlighted by the film Erin Brockovitch. Similarly, chromium(III) nutritional supplement consumption by humans and animals is rising rapidly, despite mounting concerns about their cancer risks. However, the complexity of Cr biochemistry is such that it is still poorly unde ....The Chemistry and Biochemistry of Chromium: Cancer and Nutrition. Of all of the human carcinogens, chromium(VI) has the highest level of occupational exposure, and is of increasing concern as an environmental carcinogen, as highlighted by the film Erin Brockovitch. Similarly, chromium(III) nutritional supplement consumption by humans and animals is rising rapidly, despite mounting concerns about their cancer risks. However, the complexity of Cr biochemistry is such that it is still poorly understood. This project aims at providing new insights into Cr biochemistry that are of relevance in evaluating risk factors for occupational and environmental exposure and for producing safer Cr dietary supplements.Read moreRead less
Understanding the mechanisms that regulate the human signal recognition particle cycle. The precise cellular localisation of proteins is a fundamental process in cell biology required for survival. The aim of this project is to understand the mechanisms by which the human signal recognition particle delivers newly translated proteins to their cognate cellular location.
Unified platform for real time QA in radiation therapy in brachytherapy based on high resolution silicon detectors (Magic Plate). This project will design and manufacture new devices for measuring the amount of radiation given to the patient during radiotherapy. This will improve the accuracy and safety of cancer treatment as well as greatly reducing the time needed to perform essential safety checks.
Novel imaging technologies for continuous measurement of tracer kinetics in awake animals. The fates of biologically relevant molecules, such as proteins and antibodies, in the body are fundamentally important for understanding the mechanisms and treatment of disease. This project will enable for the first time continuous imaging of the location and time course of labelled molecules in conscious, freely moving animals.
The “New” Biochemistry of Polyamines: When Metabolic Pathways Collide. Basic biochemistry and the metabolic regulation of proliferation remain as the fundamental building blocks of knowledge in cell biology that have enabled breakthrough advances in biology and medicine. Polyamines are unique and ubiquitous low-Mr amines that play vital roles in many biological processes, including proliferation, DNA/RNA synthesis, etc. This proposal will mechanistically dissect the "new" biochemistry of polyami ....The “New” Biochemistry of Polyamines: When Metabolic Pathways Collide. Basic biochemistry and the metabolic regulation of proliferation remain as the fundamental building blocks of knowledge in cell biology that have enabled breakthrough advances in biology and medicine. Polyamines are unique and ubiquitous low-Mr amines that play vital roles in many biological processes, including proliferation, DNA/RNA synthesis, etc. This proposal will mechanistically dissect the "new" biochemistry of polyamines, as we have discovered that polyamines are regulated by iron at 2-major levels, involving >10-key polyamine pathway proteins. This proposal represents first-in-field studies specifically designed to dissect mechanisms involved in this relationship. Our Central Hypothesis is that iron regulates polyamine metabolism.Read moreRead less
Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
