Summary
Levels of abdominal fat are closely correlated with metabolic syndrome. We propose experiments to identify unique characteristics (neurotransmitters or receptors) of neurons deep in the brain that project specifically to this type of fat or other less harmful subcutaneous fat. We can then test the functional significance of these unique elements in animal experimets involving gene knockdown or pharmacological approaches to modify their function and test the effect on fat distribution
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.
Dietary Therapies For The Treatment Of Drug-resistant Epilepsy

Summary
Epilepsy affects about 225,000 Australians, with 30% of suffers still experiencing seizures despite being on medications. A reduction in seizures can significantly improve the health of people with epilepsy who do not respond to medications. Low carbohydrate, high fat diets are a well-established treatment option in children, but this has not previously been studied in Australian adults. The aim of this research is to evaluate if dietary therapies are an effective treatment in adult epilepsy.
Functional Effects Of Polymorphic Variation Of The Aromatase (CYP19) Gene On Enzyme Activity:relationship To Disease

Summary
After menopause, oestrogen synthesis changes from an ovarian to an adipose source by concersion of androgens to estrogens, a process catalyzed by aromatase, the product of the CYP19 gene. We will generate mutants of the CYP19 gene that we have previously found in humans by site-directed mutagenesis and observe the effects of these mutants on aromatase function. This research will help with diagnosis and treatment of breast and other cancers and osteoporosis in humans .
The Physiology Of Brown Adipose Tissue In Adult Humans

Summary
Brown fat, unlike ordinary fat generates heat by burning calories to maintain body temperature. Originally thought to disappear after birth, recent research including our own have shown that brown fat exists in adult humans in varying amounts. Our aim is to find ways of turning on people�s brown fat allowing them to lose weight by burning more calories.
Adipose Triglyceride Lipase: Regulation And Implications For The Aetiology Of Insulin Resistance

Funding Amount
$323,453.00
Summary
Obese individuals have elevated fat levels in the blood and muscle, which contributes to the development of other diseases such as type 2 diabetes. A newly discovered protein named adipose triglyceride lipase (ATGL) is essential for fat breakdown. This project aims to identify how ATGL operates and determine whether defective ATGL function leads to type 2 diabetes. These studies will assist in the development of strategies aimed at reducing fatty acids in blood and muscle.
