Many heart diseases are associated with impairment of energetics of the heart. Improving the heart's energetics can lead to improved survival and long-term outcomes. Perhexiline is a heart medication that works by improving the way the heart uses energy. Although effective, it is associated with long-term toxicities. Better understanding of this medication may lead to less adverse effects and also provide a basis for further investigation of drug development in the future.
Control Of Anabolic And Catabolic Pathways By AMPK

Summary
This project focuses on the role of the metabolic stress-sensing enzyme AMP-activated protein kinase (AMPK) in the control of glucose and fat metabolism. AMPK has been linked to the regulation of exercise capacity, longevity and the control of insulin sensitivity. This is important for our understanding of the metabolic dimensions of our Nations most important health problems including, type-2 diabetes, cardiovascular disease, obesity, neurodegeneration as well as other age onset diseases.
IMPAIRED REGULATION OF CYTOCHROMES P450 DURING THE EVOLUTION OF HEPATIC STEATOSIS

Summary
The accumulation of fat in liver is a common problem in early liver injury caused by alcohol, certain drugs and diseases like diabetes. When this occurs the fats can change the amounts of a number of genes and proteins in liver. Cytochrome P450 proteins insert an activated form of oxygen into chemicals, including drugs and fats. In the process, however, some of these activated chemicals can damage surrounding tissues. This project will study the details of how the levels of cytochromes P450 are ....The accumulation of fat in liver is a common problem in early liver injury caused by alcohol, certain drugs and diseases like diabetes. When this occurs the fats can change the amounts of a number of genes and proteins in liver. Cytochrome P450 proteins insert an activated form of oxygen into chemicals, including drugs and fats. In the process, however, some of these activated chemicals can damage surrounding tissues. This project will study the details of how the levels of cytochromes P450 are altered when fat accumulates in liver. The findings may suggest ways in which normal levels of cytochromes P450 can be restored and how to minimise the injurious effects of activated chemicals in liver.Read moreRead less
Manipulation Of Energy Metabolism To Control Lipid Accumulation And Insulin Action.

Summary
I am a metabolic biochemist investigating how overconsumption of calories, particularly fat, results in dysfunctional energy metabolism and increased the risk of type 2 diabetes. I examine changes in the daily rhythms of energy intake, energy utilisation and energy storage in different tissues of dietary and genetically modified animals to pinpoint novel ways of reducing fat accumulation and reducing the risk of type 2 diabetes.
Role Of AMPK Signaling In Metabolic Control During Exercise

Summary
It is well recognized that sedentary life styles are associated with increased incidence of obesity, Type 2 diabetes and atherosclerotic cardiovascular disease. The medical, social and financial costs of these diseases are growing rapidly and represent a major health care challenge. Exercise is beneficial for maintaining health in patients at risk of developing these diseases and for this reason we are interested in understanding how exercise capacity is regulated.
