Examining novel cell signalling in the regulation of platelet structure and function. Pharmaceutical inhibition of platelet function is the primary therapy for prevention of arterial thrombosis – the most common cause of death and disability in Australia. However, current therapies have limited efficacy. Defining platelet activation mechanisms in order to rationalise more effective antithrombotic approaches is the major focus of this research. This project describes the first studies to examine ....Examining novel cell signalling in the regulation of platelet structure and function. Pharmaceutical inhibition of platelet function is the primary therapy for prevention of arterial thrombosis – the most common cause of death and disability in Australia. However, current therapies have limited efficacy. Defining platelet activation mechanisms in order to rationalise more effective antithrombotic approaches is the major focus of this research. This project describes the first studies to examine the importance of a family of intracellular signalling enzymes, the Class II phosphoinositide 3-kinases, in platelet function. These studies will define the contribution of these enzymes to platelet production and function and will establish whether their inhibition is an attractive strategy for the prevention of arterial thrombosis.Read moreRead less
Muscling in on the brain. This project investigates an enzyme that 'matures' neurotransmitters in the brain that regulate food intake, energy expenditure and blood pressure by the brain; these neurotransmitters arise from the same precursor molecule. This project will show the physiological relevance of this enzyme in obesity.
Novel mechanisms controlling signaling by adenosine monophosphate-activated protein kinase, central regulator of energy homeostasis. Sedentary lifestyles and consumption of high energy foods have led to dramatic increases in the incidence of obesity-related metabolic diseases such as type 2 diabetes and cardiovascular disease, placing enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK), which fu ....Novel mechanisms controlling signaling by adenosine monophosphate-activated protein kinase, central regulator of energy homeostasis. Sedentary lifestyles and consumption of high energy foods have led to dramatic increases in the incidence of obesity-related metabolic diseases such as type 2 diabetes and cardiovascular disease, placing enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK), which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Building on recent breakthroughs made at St. Vincent's Institute, this project will produce innovative research into novel mechanisms that control AMPK. These discoveries will greatly increase our understanding of AMPK regulation by cellular processes, and aid the design of more effective AMPK drugs.Read moreRead less
The combined use of proteomics and small molecules for target identification and pathway analysis. This project intends to investigate how a series of new small molecules identified from our research to improve the metabolic effects of insulin. This project will integrate medicinal chemistry with proteomics and metabolic biology to identify the cellular targets and their mechanism of action.
