Summary
Damage to the heart from coronary vascular disease causes significant morbidity and mortality in Australia. Indeed, ischaemic injury represents the single greatest cause of premature death. Moreover, due to the increasing age of our population the problem is growing - coronary artery disease affects 50% of those older than 65, contributing to an increased incidence of angina pectoris, myocardial infarction, arrhythmia, congestive heart failure, and sudden death. Protective strategies have been, ....Damage to the heart from coronary vascular disease causes significant morbidity and mortality in Australia. Indeed, ischaemic injury represents the single greatest cause of premature death. Moreover, due to the increasing age of our population the problem is growing - coronary artery disease affects 50% of those older than 65, contributing to an increased incidence of angina pectoris, myocardial infarction, arrhythmia, congestive heart failure, and sudden death. Protective strategies have been, and continue to be, developed to reduce the extent of tissue damage and minimise prolonged reductions in heart function. The success of these interventions has been mixed. This research project takes the novel approach of identifying the true roles of two receptors present in the heart (the adenosine A1 and A3 receptors) which may play a crucial role in enhancing tolerance of the heart to disease and injury. We currently do not fully understand the roles of these receptors, although preliminary findings suggest they can exert powerful protective effects during disease conditions. From a fundamental viewpoint, identifying the roles of these two receptors will significantly advance our understanding of the mechanisms of injury and protection in the heart. From a therapeutic viewpoint, this study will take us closer to the potential use of adenosine receptor-based therapy in protecting the heart from ischaemic injury.Read moreRead less
Transgenic Expression Of The EWS-WT1 Fusion Protein,inducing The Development Of Tumour That Replicates The Human Disease

Summary
A genetic translocation encoding the EWS-WT1 fusion protein is found desmoplastic small round cell tumours. Our aim is to examine the effect of this protein in inducing tumour growth in tissue cell lines. A virus will then be used to introduce the genetic translocation into mice to examine the effect of this protein on tumour growth in a mammal, thereby serving as a 'solid tumour model' to try and identify therapeutic targets.

The cross-disciplinary team performing this research will examine how mobile DNA elements found in brain cells move in response to learning and memory exercises in mice, and whether these changes generate an address system for parts of the brain to be turned on by specific experiences. This work has major implications for our fundamental understanding of how the brain works in healthy individuals, as well as people affected by neurodevelopmental and neurodegenerative conditions.
