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.

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
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.

Summary
Cells in our bodies are able to accomplish an impressive array of functions. Diffusible factors (called growth factors) are important in regulating diverse cellular functions. We have identified a new molecular switch inside cells that acts as a master controller of cellular functions. This molecular switch relays information to instruct specific cellular functions. We have shown that these molecular switches are short-circuited in breast cancer promoting cell growth and survival.

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.
