Sphingosine Kinase: A Target For Obesity-induced Insulin Resistance
Funder
National Health and Medical Research Council
Funding Amount
$626,845.00
Summary
Insulin resistance, a characteristic of type 2 diabetes, is linked to abnormal metabolism of lipid (fat) in tissues such as liver and muscle. This project aims to identify a novel pathway which may promote a build up of lipids in liver and therefore leads to the development of type 2 diabetes. This work may provide a basis for understanding and optimizing treatment of insulin resistance by regulating the control of fat metabolism in liver.
Lipid Metabolism In The Hypothalamus: Implications For Obesity And Diabetes Development

National Health and Medical Research Council
Funding Amount
$592,915.00
Summary
Obesity is defined by excessive fat storage and defective lipid metabolism, not only in adipose tissue, but also in most tissues throughout the body. Obesity-induced changes in lipid metabolism extends to the brain and is associated with impaired cognitive function. This work aims to determine how obesity affects neurons in the key feeding centres of the brain, and whether excessive lipid storage in neurons induces changes in body weight regulation and metabolism.
The Role Of Adipose Tissue Cholesterol In Metabolic Diseases

Funding Amount
$888,340.00
Summary
Adipose tissue is important for human health. Adipose tissue can normally store a significant amount of cholesterol. Impairment of this function will cause a number of devastating diseases such as heart disease and stroke. The proposed work will help understand how adipose tissue store cholesterol. Results from this work may lead to novel therapeutic strategies against obesity and heart disease.
Determinants Of Brown Adipose Tissue Activation - Implication For The Regulation Of Energy Balance And Obesity

Summary
One of the most important recent findings in the biology of obesity has been the revelation that brown adipose tissue (BAT) is present and functional in adult humans. Even more important, the amount of BAT seems to be related to the extent of obesity. The challenge now is to harness the means by which BAT is activated. Understanding the central neural control pathways and the rate limiting steps in the BAT itself will pave the way for new anti-obesity strategies.
Role Of The Drug Metabolising Enzyme Arylamine N-acetyltransferase 1 In Breast Cancer

Funding Amount
$600,196.00
Summary
The current project will identify the molecular mechanism(s) that underpins the significant changes in phenotype seen in a range of human cancer cells. The expected outcomes will be to demonstrate that NAT1 is critical for the clearance of pABG in cancer cells. The results will be important in the context of understanding this family of intracellular enzymes and will change the current thinking on the function of the arylamine N-acetyltransferase in normal and cancer cells.
Glutathione Transferase Zeta: A Novel Regulator Of Glucose And Lipid Metabolism
Funder
National Health and Medical Research Council
Funding Amount
$604,143.00
Summary
Obesity is a problem of global significance as a cause of preventable illness and death. The many consequences of obesity including cardiovascular disease, type 2 diabetes, cancer and osteoarthritis are an increasing burden on affected subjects and on the health care system. Our recent studies have revealed a novel pathway for the regulation of obesity. This discovery has provided a new target for the development of drugs for obesity and related disorders.
Role Of Microvascular Flowmotion In Skeletal Muscle Glucose Metabolism

Funding Amount
$596,971.00
Summary
Obesity and type 2 diabetes are nationally and globally reaching epidemic rates. This project investigates the regulation of blood flow within muscle and its impact on metabolism. Outcomes from the study may lead to diagnostic tools and treatments for cardiovascular disease associated with obesity, hypertension and type 2 diabetes.

Bioenergetic Deficit In Neurodegeneration: Studies In Motor Neuron Disease (MND)
Funder
National Health and Medical Research Council
Funding Amount
$300,967.00
Summary
Motor neurone disease (MND) is a fatal neurodegenerative disease. There is no known cause and no known cure. We believe that a defect in the way in which the muscle and nerve cells generate energy to sustain survival causes for there to be added metabolic stress on their already high energetic load, ultimately leading to cell death. This project aims to understand the vicious cycle of energy deficiency that leads to the catastrophic events that cause the death of muscle and nerve cells.
Understanding The Role Of Sugar Metabolism In Liver Tumour Growth
Funder
National Health and Medical Research Council
Funding Amount
$631,979.00
Summary
Primary liver cancer is a deadly disease with limited chemotherapeutic options. The investigators of this proposal have recently determined that sugar intake (but not fat or complex carbohydrate) is a dominant driver of liver tumour growth in mice. The current proposal will investigate the specific contributions of glucose versus fructose in tumour burden, and determine whether blocking the conversion of sugars to fat in the liver represents a therapeutic strategy to block tumour growth in mice.
