The Recently Discovered (pro)renin Receptor: Examination Of Its Role In Diabetes And Heart Disease

Summary
It is thought that a protein known as the (pro)renin receptor may cause cardiovascular disease, however little is known about its role in normal cell function. My project will investigate the normal function of this protein and determine what role it has in cardiovascular disease. This information will be essential for the development of new drugs. I will be conducting this research in a prestigious overseas laboratory, where I will learn new skills that I can bring with me back to Australia.
Phospholipase Cbeta 1b, A Target To Limit Atrial Dilatation

Summary
We have identified a heart specific protein that is involved in perpetuating dilatation of the upper chambers of the heart and thereby contributing to cardiac disease. Inhibitors of this protein provide a suitable target for therapy to limit heart disease. The current studies aim to test such inhibitors in vivo as proof-of-concept that such treatment effectively limits cardiac dysfunction.
New CaMKII Therapeutic Targets In Heart Failure With Preserved Ejection Fraction

Funding Amount
$740,335.00
Summary
Deaths associated with impaired heart muscle relaxation and unstable cardiac cycle rhythm are increasing. The mechanisms by which these pathologies occur are not understood and clinical therapies are lacking. We have novel evidence to suggest that a key signalling protein, CaMKII, is critically involved in the development of these forms of heart pathology. This goal of this project is to identify how CaMKII is implicated in heart failure and dysrhythmia as a basis for designing new therapies.
Identifying And Developing Novel Therapeutic Approaches For Heart Disease

Summary
Increasing rates of obesity, diabetes, and an ageing population increase the risk of heart disease & complications including heart failure (HF), atrial fibrillation (AF), and diabetic heart disease. There is a clinical need for i) improved therapies for patients with HF, AF, and diabetic heart, and ii) biomarkers which more effectively recognise people at risk of heart disease, to prevent clinical events. My research program is designed to develop novel therapies and identify new biomarkers.
Insulin Regulated Aminopeptidase: A New Cardiovascular Target

$672,650.00
Summary
Cardiovascular disease, leading to heart attack or stroke is the largest cause of death in Australia. We have evidence that inhibition of a newly described enzyme (IRAP) by angiotensin IV is protective in a model of atherosclerosis. Excitingly we have preliminary data indicating that mice deficient in IRAP have better vascular function therefore we will further investigate this as well as the effectiveness of newly developed IRAP inhibitors in preventing development of cardiovascular disease.

Summary
All of biology and disease is based on cells receiving signals from hormones and growth factors via cell surface receptors. Cells integrate these signals to give a response which may be cell growth or the secretion of further hormones and growth factors. Signals from receptors can intersect to modify the response. This project will explore a new interaction we have discovered where a hormone activates its receptor to cause the activation of a growth factor receptor potentially providing new drug ....All of biology and disease is based on cells receiving signals from hormones and growth factors via cell surface receptors.

SHANK3 As A Target To Reduce Hypertrophy And Heart Failure

Summary
We have identified a large protein in heart that functions to facilitate the heart's response to disease. The proposed studies will define how this protein mediates responses and whether we can successfully interfere with the process to limit disease progression.
Molecular Mechanisms In Pregnancy-indcuded Hypertension

Summary
Approximately 5-10% of pregnancies are complicated by hypertension with associated health risks for both mother and child. To keep blood pressure at normal levels during pregnancy requires active regulation, but underlying processes are not yet fully understood. We have identified a molecule which crucially controls blood pressure during pregnancy. In this proposal we will study how the molecule remodels blood vessels in pregnant females to optimize pharmacological intervention and pregnancy out ....Approximately 5-10% of pregnancies are complicated by hypertension with associated health risks for both mother and child. To keep blood pressure at normal levels during pregnancy requires active regulation, but underlying processes are not yet fully understood. We have identified a molecule which crucially controls blood pressure during pregnancy. In this proposal we will study how the molecule remodels blood vessels in pregnant females to optimize pharmacological intervention and pregnancy outcomes in humans.Read moreRead less
Mechanism Of Epidermal Growth Factor Receptor Transactivation

$578,268.00
Summary
This application examines the cellular events that control heart growth in response to angiotensin, a hormone linked to heart failure. We believe that the same cell processes are also involved in cancer cell growth and by understanding the mechanism by which angiotensin promotes growth, better therapies against human cardiovascular disease and its relationship to uncontrolled growth will evolve.
Novel Therapeutic Interventions To Increase Blood Flow To Skeletal Muscle

Summary
Over the past decade it has become clear that the cytokine interleukin (IL)-6 is produced in and released from tissues such as fat and muscle to mediate metabolic processes. In this respect, it acts in a hormone like manner. During this period it has also become apparent that the hormone insulin increases blood flow to skeletal muscle. There is emerging evidence that IL-6 plays a role, not only in metabolic and signalling processes within skeletal muscle, but also in blood flow. This project wil ....Over the past decade it has become clear that the cytokine interleukin (IL)-6 is produced in and released from tissues such as fat and muscle to mediate metabolic processes. In this respect, it acts in a hormone like manner. During this period it has also become apparent that the hormone insulin increases blood flow to skeletal muscle. There is emerging evidence that IL-6 plays a role, not only in metabolic and signalling processes within skeletal muscle, but also in blood flow. This project will determine whether the cytokine IL-6 is a viable therapeutic target in the treatment of blood flow disorders in patients with type 2 diabetes. This has major ramifications since type 2 diabetes has reached pandemic levels in Australia and is estimated to cost the community approximately 800 million dollars per year.Read moreRead less
