I study hormone action at the molecular level, particularly that of growth hormone action. I focus on the mechanism of activation of its receptor, notably as a target for cancer therapy, since growth hormone is necessary for the progression of many types of cancer. The ability of growth hormone to activate neural stem cells for a prolonged period in response to voluntary exercise is also a key interest. So too is the 40% extension of lifespan in mice after genetically deleting the growth hormone ....I study hormone action at the molecular level, particularly that of growth hormone action.

Determination of cellular mechanisms underpinning cancer cell metastasis through integrated in vivo imaging approaches. Understanding key steps that drive the spread of cancer is critical to improve current treatment strategies. Using cutting-edge imaging technology and in vivo model systems that mimic the disease, this project will pinpoint key events that are susceptible to drug intervention and identify new therapeutic targets.

Summary
Structural insights into adenosine receptors. This project aims to investigate mechanisms underlying ligand binding and signal transduction at G protein-coupled receptors (GPCRs) by utilising the adenosine receptor family as a model system. This interdisciplinary project will use structural biology, pharmacology and biochemistry. The expected outcomes include understanding ligand selectivity across the four adenosine receptor family members. This should provide significant benefits, such as adva ....Structural insights into adenosine receptors.

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

This project expects to generate knowledge in the area of GPCR biology using an interdisciplinary approach including structural biology, pharmacology, biochemistry and protein engineering. The expected outcomes include (i) understanding the structural mechanisms underlying GPCR activation, (ii) biased agonism and (iii) G protein selectivity. This should provide significant benefits, such as advancement of fundamental knowledge in GPCR biology and pharmacology that could also one day lead to therapeutic development.Read moreRead less
A biological model to understand caveolin-1 and lipid raft function in health and disease. This project will generate a biological model for pathological caveolin-1 action on cell membrane domains called lipid rafts to determine how they trigger chronic diseases such as cancer and diabetes. The tools developed in this project will help Australia find new drug targets for the treatment and prevention of these prevalent diseases.
Molecular mechanisms of cyclic Adenosine Monophosphate (AMP) induced apoptosis. Cyclic Adenosine Monophosphate (cAMP) is an important cellular chemical necessary for cell growth. However, de-regulated cAMP production in response to altered physiology can result in cellular death or apoptosis. This is attributed to the development of certain human diseases and this project aims to understand the molecular mechanism behind this process.
Investigation of the biology of insulin-like growth factor 1 and its derivatives for the development of new therapeutics. This project will investigate the biology of insulin-like growth factor 1, a key molecule in growth, development and, in particular, the wound healing process. Its success will lead to improved treatments for non-healing (chronic) wounds and, potentially, new anti-cancer treatments.
Dissecting the mitochondrial pathway of apoptotic cell death. This research aims to identify each step in cell death regulation by the Bcl-2 family of proteins. Each step is a potential target for drugs that may help cancer cells die, or that may help normal cells such as heart and brain cells recover from damage.
A new Src, PKCdelta and Akt regulated protease activated receptor system in metastasis. In contrast with localised cancer which can often be cured, curative treatment is generally not possible for cancer that has spread. This project will characterise a protein that drives the spread of cancer and to develop new approaches to treat patients at risk of developing these aggressive tumours that spread to other organs.
