Summary
Young people with obesity often have no signs of cardiovascular disease but their organs, such as the heart, the kidneys and the blood vessels present early evidence of damage that can, in time, progress to confer cardiovascular risk. This study will look at the potential beneficial effect of a drug, by itself or in association with a low calorie diet, in reversing the progression of organ damage in young obese subjects.
TARGETING THE CHK1-STAT3-CIP2A AXIS TO TREAT GLIOBLASTOMA (GBM)

Summary
Glioblastoma (GBM is a high-grade brain tumour for which current treatments are inadequate. Tumour recurrence is almost inevitable and average life expectancy is measured in months. We have identified a DNA-damage signalling pathway and demonstrated that perturbation of the pathway significantly reduces tumour growth. We plan to target key proteins of the recently identified pathway and validate these findings using tumour cells directly from GBM patients and relevant animal models of human GBM.
Identification Of Novel Mediators Of Bone Catch-up Growth

Summary
Musculoskeletal growth disorders cause significant suffering in children and impair new workforce generations before their working life starts. Despite this relevance, non-invasive methods to induce growth recovery of impaired bones are an unmet need, as we lack sufficient understanding of how this process works. To address this knowledge gap, we generated mouse models that will allow us to reveal foetal mediators of compensatory growth that could be reactivated postnatally to boost bone growth.
Induction Of Islet Transplant Tolerance In A Humanised Mouse Model

Summary
The current treatment for type 1 diabetes (T1D) is insulin therapy, but it cannot fully prevent chronic complications. Also intensive insulin use increases the risk of fatal hypoglycemia. An emerging therapy which may overcome or at least reduce these problems is the transplantation of human islet cells. But preventing the immune system from rejecting these cell transplants is still a major challenge. This study will develop new therapeutic strategies to protect these transplants from rejection.
Hormonal Resuscitation And P38 MAP Kinase Inhibition To Enhance Quality Of Cadaveric Donor Organs For Transplantation

Summary
The transplantation of organs such as the heart, lung, liver, kidney and pancreas from brain-dead donors is limited primarily by the shortage of donor organs. It is now recognised that as many as 25% (one in four) potentially usuable donor organs are lost after brain death due to the rapid deterioration that occurs in organs after brain death. There is evidence that this deterioration is due to loss of the normal hormones that are essential to the normal functioning of these organs.

It is now recognised that as many as 25% (one in four) potentially usuable donor organs are lost after brain death due to the rapid deterioration that occurs in organs after brain death. There is evidence that this deterioration is due to loss of the normal hormones that are essential to the normal functioning of these organs. In this project, we will use a pig model of brain death that we have extablished in our laboratory to examine the effects of hormone replacement on the function of organs that are used for transplantation. We will also test a novel drug aimed at protecting donor organs during the period between removal of the organ and transplantation. If successful, these treatments have the potential to markedly increase the numbers of organ transplants and to improve the outcomes for recipients of these transplants. In the Australian and New Zealand setting, a 25% increase in the number of donor organs would results in approximately 220 more people per year receiving these life-saving operations.Read moreRead less
Global Data Mapping And Evaluation Of Needs, Capacities And Benchmarks In Organ Donation And Transplantation: Informing Effective Local And International Health Policy To Better Meet The Needs Of Patients

Funding Amount

Summary
Global shortages of donor organs limit the provision of reliable and equitable access to solid organ transplantation. As a result, many are excluded from waiting lists, others deteriorate whilst awaiting transplantation, and some seek to purchase the needed organ. Countries have a responsibility to provide transplantation services sufficient to meet population need. This project evaluates international data for key interventions that may impact on waitlisting, donation and transplant practices.
NEURAL MODULATION OF HEARING LOSSES INDUCED BY LOUD SOUND

Summary
Loud sounds, from occupational and recreational sources, are the most common threat to hearing and can result in temporary hearing losses (as might be experienced after an evening at a noisy pub or concert) or permanent hearing losses (after prolonged or multiple loud sounds, as for example in a noisy work environment). Noise reduction programs are either not always possible or effectively applied.

Noise reduction programs are either not always possible or effectively applied. A parallel strategy is the study of biological mechanisms that may ameliorate hearing damage, with a view to optimising such mechanisms. I propose to build on seminal Australian work to examine how one such system, nerves from the brain to the inner ear (the site of most damage from loud sounds), modulates hearing losses caused by loud sounds. Early studies indicated these nerves could protect from damage induced by short-lasting loud sound and this has led to international interest in functional applications of such protection to reduce hearing damage suffered by humans. However, my recent work indicates the nerves exert complex protective and exacerbative effects to loud sounds similar to common trauma or occurring under conditions similar to common trauma. They even exacerbate hearing losses due to loud sound, especially when there is an imbalance in hearing sensitivity in the two ears (bilateral) similar to what is common in humans. These findings make it critical that functional application be delayed until the full range of effects exerted by the nerves is understood. I propose to elucidate the novel complex effects of these nerves to loud sound. Specific aims are: (1) To understand effects of these pathways to loud sounds like those encountered by humans, (2) To investigate how chronic imbalanced bilateral hearing sensitivity, like that common in humans, alters effects of the nerves and when they change from being protective to exacerbative, (3) To adduce how an atraumatic sound affects hearing losses due to later loud sound and the role played by these nerves.Read moreRead less
A Novel Strategy For The Treatment Of Chronic Skeletal Joint Defects

Summary
Skeletal joint injuries often heal poorly with current treatment approaches and lead to the onset of osteoarthritis. This project will produce a synthetic graft with unique properties to mimic the complex structure of joint tissues, and high bioactivity to induce optimal healing of the joint. This graft will constitute a viable alternative for the treatment of skeletal joint defects, resulting in significant healthcare benefits and improved long-term outcomes.
Improved Patient Outcomes Through Dosage Individualisation Of The Newer Immunosuppressant Drugs

Summary
After organ transplantation, recipients need to take medicines continually to stop their immune system from rejecting their new organ. This treatment with immunosuppressant drugs is vital for long-term success of their graft. However, too many people are losing their transplant or are experiencing drug toxicity or infection due to poorly managed immunosuppression. The project aims to accurately define the best way to dose newer immunosuppressant drugs in Australian transplant populations.
