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
Women's Hormones And Health Across The Adult Life Span

Summary
Sex hormones are important in younger and older women’s health. However, normal levels of sex hormones for women of different ages and the extent to which sex hormones are associated with common health outcomes are yet to be established. These issues will be systematically studied in comprehensive, community-based studies of younger and older Australian women. The findings will be immediately translated into clinical practice guidelines and community education.
Aromatase Regulation By P53 And HIF-1alpha In Obesity And Post-menopausal Breast Cancer.

Summary
Current hormone therapy for breast cancer using inhibitors of oestrogen production results in serious side-effects including bone loss, joint pain and possibly cognitive issues. Our current work is aimed at understanding how oestrogen production is regulated with the goal of developing breast-specific inhibitors of oestrogen production to obviate these problems. In addition, this work is aimed at devising therapeutic intervention to break the linkage between obesity and breast cancer.
In men, oestrogen may be important for strong bones and maintaining a healthy weight. Men with prostate cancer are given medical castration treatment to decrease testosterone, because testosterone is required for prostate cancer growth. Because oestrogen is derived from testosterone, they also have very low oestrogen levels. We want to conduct a trial in these men to find out whether giving back oestrogen will prevent bone loss and weight gain, among other health benefits.
Novel Interplay Of Oestrogen And Growth Hormone In Regulating Lipid Metabolism

Summary
These studies provide insights into the mechanisms and role of oestrogen in regulating whole body and liver fat metabolism. Oestrogen-related medications that modify the action or tissue availability of oestrogen are widely used therapeutics and can predispose to obesity and fat accumulation in the liver. Whether the effect is direct or through interplay with other metabolic hormones is unknown. This proposal examines their metabolic consequences and impact on obesity and liver health.
