Summary
The blood forming system coordinates production of cells that confer immunity to infection, transport oxygen and assist blood clotting. When the molecular mechanisms that control these functions go awry, diseases including leukaemia and autoimmunity result. This research will define fundamental molecular regulators of blood cell production and function, assess their role in blood cell diseases and explore their potential to provide leads for development of new therapeutics.
My research focuses on understanding the molecular regulation of blood cell production and function in health and disease with the ultimate goal of discovery of new treatments for blood cell diseases including leukaemia and autoimmunity.

Summary
T-cell acute lymphoblastic leukaemia (T-ALL) results from the abnormal development of T cells that are an important cell type in the body's immune system. Although the prognosis for T-ALL has improved remarkably over the last decade, for one out of five T-ALL cases the underlying genetic defects remain unresolved and are refractory to current therapies. This project aims to use both novel mouse models and human patient cell lines to better understand this disease and discover novel targets for f ....T-cell acute lymphoblastic leukaemia (T-ALL) results from the abnormal development of T cells that are an important cell type in the body's immune system.

Summary
As part of their normal function, blood vessels dilate and contract, for example in response to the pulsative force with which our heart pumps the blood around the circulation. Blood vessels produce several different chemicals that cause vessel relaxation, and these vary depending on several factors, such as the blood vessel involved, its diameter and precise location within our body. In addition to responding to the pulsative nature of blood flow, blood vessels also respond to many other condit ....As part of their normal function, blood vessels dilate and contract, for example in response to the pulsative force with which our heart pumps the blood around the circulation. Blood vessels produce several different chemicals that cause vessel relaxation, and these vary depending on several factors, such as the blood vessel involved, its diameter and precise location within our body. In addition to responding to the pulsative nature of blood flow, blood vessels also respond to many other conditions, including certain diseases, so that it is not surprising that many of the commonly used cardiovascular drugs target to change blood vessel tone, either increasing or decreasing blood pressure, depending on the circumstances involved. The present application is based on the discovery, in the mouse, that during a systemic infection a specific protein is induced in the cells that line blood vessels. This protein degrades a certain amino acid into a novel chemical, called kynurenine. We observed that kynurenine has previously unrecognised vessel-relaxing properties. The present project will investigate the importance of kynurenine formation as a novel pathway in the regulation of vascular tone. Mice, in which the activity of the kynurenine-producing protein will be modulated (both up and down) will be used in conjunction with blood pressure and other relevant measurements. In addition, the role of a unique molecule, called superoxide anion radical, in the production of kynurenine by the protein will also be tested. If our results confirm that the protein and kynurenine are indeed involved in regulating vascular tone, our research could have tremendous impact on many aspects of normal physiology as well as cardiovascular diseases that remain the major single cause of death in Australia.Read moreRead less
Use Of Snake Venom Prothrombin Activators In Blood Collection Tubes To Produce High Quality Serum To Improve Patient Outcomes

Funding Amount
$284,706.00
Summary
The timely availability of high quality serum and plasma samples are of the utmost importance for accurate biochemical analysis in a clinical setting. This requirement is particularly true for patients on anti-clotting therapeutic agents such as warfarin and heparin. In this study we will employ potent prothrombin activators purified from snake venom to enhance the clotting efficiency of blood for serum preparation for biochemical analysis.
LIFEPATH: Life-course Biological Pathways Underlying Social Differences In Healthy Ageing

Funding Amount

Summary
Healthy ageing varies across society due to environmental, behavioural and social circumstances that affect peoples’ lives. To improve our ability to change this we will investigate suspected biological mechanisms over the life course. Using repeated blood samples collected during a large prospective study, we will measure a very large number of biological markers and analyse these combined with lifestyle and behavioural information to identify the modifiable predictors of healthy ageing.
Identifying Donor And Recipient Gene Pathways In Renal Transplant Fibrosis

Summary
We have identified a 13 gene set that predicts renal transplant fibrosis and graft loss in patients. Interestingly some of these gene are donor as well as recipient related. In this project we aim to investigate these gene pathways in cell lines and animal models to better understand how the cause of renal fibrosis after transplantation.
