Summary
Cardiovascular diseases, including hypertension, remain one of the largest causes of morbidity and mortality in Western populations. We have identified a molecule, called Regulator of G protein signalling 5 (RGS5), which is involved in pathological vessel remodelling and in the regulation of blood pressure. This molecule is a prime candidate for drug development. We will study the precise role of RGS5 in cardiovascular disease models and regulatory pathways in cell systems.

Summary
Cancer and cardiovascular diseases are amongst the largest causes of morbidity and mortality in Western populations. We have identified a molecule, called Regulator of G protein signalling 5 (RGS5), which is involved in vessel remodelling in both diseases. This molecule is a prime candidate for drug development. We will study the precise role of RGS5 in sophisticated preclinical models which will create future opportunities for urgent therapy.

Summary
Maintenance of skeletal muscle mass is essential for human health and locomotion. In ageing and cancer, loss of muscle mass leads to severe weakness and immobilization causing morbidity and mortality. This grant aims to characterise a novel gene that when deleted in mice leads to significant muscle damage. The molecular pathways within the cell that lead to the observed muscle damage will be investigated and this may provide insights into the pathways that control muscle damage and its regenerat ....Maintenance of skeletal muscle mass is essential for human health and locomotion.

Cancer causes significant morbidity and mortality in Australia’s aging population. There is strong evidence that abnormal blood vessels in tumours limit drug access and drive metastases. We have identified a molecule which controls vessel remodelling in tumours. In this proposal we will study mechanisms on how the molecule itself is regulated with the aim to normalize blood vessels for improved therapy.
Skeletal Muscle Signal Transduction Related To Exercise, Metabolic Disease And Human Health

Summary
Exercise is one of the best prevention and treatment strategies for all major human diseases. Despite these well documented advantages, we still do not know exactly how exercise produces these benefits at the molecular level. A comprehensive understanding of this will lead to new avenues to treat many diseases. This project will monitor thousands of molecular changes that occur in human muscle biopsies following exercise and create the world’s first molecular blueprint of exercise.
Characterisation Of Autophagy Deficiency In Skeletal Muscle Homeostasis

Summary
Defects in skeletal muscle are a cause of muscle disease, and also have broad health implications for diabetes, obesity and liver disease. As such, it is important to understand the processes required for healthy muscle and how signals communicate from muscle to the liver and fat, which integrate whole body metabolism. This application examines how the cellular degradation process known as autophagy integrates these important processes by investigating a novel gene regulator of this pathway.
The Characterization Of A Novel Pseudokinase Regulator Of Platelet Formation

Funding Amount

Summary
Mammalian cells contain a complex switchboard, which directs the cell to grow, die, multiply or move in response to external cues. When communication breaks down within the cell, diseases arise. Our studies are directed towards identifying the molecules that comprise the switchboard which directs blood cell formation. A detailed understanding of the regulators of blood cell formation will equip us with a sound starting point for designing drugs to ameliorate blood diseases.
Retinoic Acid Receptor-related Orphan Receptors And The Regulation Of Metabolism:insights Into Diabetes And Obesity

Summary
Nuclear receptors (NRs) function as hormone dependent DNA binding proteins important in sustaining human health, highlighted by the array of medicines that target these proteins for human well being. ROR alpha is one such protein that we have shown regulates fat mass, obesity, and glucose tolerance. Obesity and diabetes are often linked with inflammation. We will examine how ROR controls inflammation during metabolic disease.
