Funding Amount
$684,607.00
Summary
Human melanocortin receptors play a key role in a variety of physiological processes ranging from energy regulation, skin pigmentation and regulation of food intake. This project aims to generate novel peptide based molecules that will selectively interact with different melanocortin receptors to better understand their pharmacology thereby opening the potential for future drug development for obesity, stroke or inflammatory skin disorders.
Development And Application Of A Novel Ultrasensitive LC-MS Estradiol Assay
Funder

Funding Amount
$240,400.00
Summary
This project will develop a new ultrasensitive method using liquid chromatography-mass spectrometry to measure extremely low level of circulating estrogens in the bloodstream especially in mice. This will allow for the first time the ability to study the natural regulation of fertility in mice and other sub-primate mammals for which the present assay methods are not adequate.
Elf5 And The Basis For Antiestrogen Resistant Breast Cancer

Funding Amount
$1,181,326.00
Summary
Resistance to anti estrogen therapies causes half of breast cancer deaths. We have recently discovered (Plos Biol 2012) that the transcription factor Elf5 is intimately involved in this process. This grant will develop our understanding of the transcriptional and genomic events involving Elf5 that lead to antiestrogen resistance and metatstasis, to develop new models of antiestrogen resistance, biomarkers that predict antiestrogen resistance and new therapeutic targets and strategies that preven ....Resistance to anti estrogen therapies causes half of breast cancer deaths.

Do Sex Hormones Slow Biological Ageing To Improve Health Outcomes In Men?

Funding Amount
$249,569.00
Summary
As the Australian population ages their burden of ill-health increases. Our earlier research showed that higher sex hormone levels are associated with better health outcomes in older men. In this project, we will address the question whether exposure to higher sex hormone levels slows biological ageing in men, reflected in the presence of longer chromosomal ends called telomeres. If so, interventions that raise hormone levels could be tested to preserve health in ageing men.
Adjunctive Hormone Therapy For Treatment Resistant Depression In Perimenopausal Women

Funding Amount
$620,946.00
Summary
Women entering the menopause have increased rates of treatment resistant depression with poor response to standard antidepressant treatment. We propose to conduct a clinical trial of a novel adjunctive hormone, tibolone, to improve the outcomes for middle – aged women with severe depression.
Hormone Transport By Alpha-2-Macroglobulin: Novel Roles In Regulating Hormone Activity
Funder
National Health and Medical Research Council
Funding Amount
$602,857.00
Summary
Alpha-2-macroglobulin is a large protein in the blood known to bind and transport numerous hormones in the circulation. Our previous studies published in BLOOD (2009) and JBC (2013) have discovered an important role for this molecule in the transport and regulation of a peptide hormone. The studies proposed in this application have important implications for understanding new roles of alpha-2-macroglobulin in hormone binding and regulating the activity of hormones in disease states.
Selective Estrogen Receptor Modulators - A New Adjunctive Treatment For Men With Schizophrenia?
Funder
National Health and Medical Research Council
Funding Amount
$816,603.00
Summary
One-third of people with schizophrenia do not respond well to antipsychotic medication treatment.There is an urgent need to develop new treatments.We have conducted world-first studies showing that estrogen treatment is highly successful in treating women with schizophrenia.Our research is a trial of SERM (selective estrogen receptor modulator), a new form of “brain estrogen” in men with persistent schizophrenia. We hope to reduce the disability caused by persistent psychotic symptoms.
Effects Of Dietary Amino And Fatty Acids On Energy Intake And Glycaemia - Implications For Novel Approaches To The Management Of Obesity And Type 2 Diabetes
Funder

Funding Amount
$584,032.00
Summary
Current obesity treatments are limited in efficacy or have adverse effects. Our research has shown that specific fatty acids and amino acids markedly suppress energy intake and reduce blood glucose, without adverse effects. The goal of the proposed work is to evaluate the translational potential of these discoveries in obese diabetic patients. Ultimately, we hope to develop the findings from this research into novel, nutrient-based strategies for the management/prevention of obesity/diabetes.
Thyroid cancer is the commonest endocrine malignancy, and typically affects younger adults. Despite low mortality rates, local recurrence is not uncommon and re-operative surgery can cause significant morbidity. We are studying genetic variants in thyroid transcription factors associated with thyroid cancer predisposition. Our work will determine the mechanism of this association, and provide new strategies for early diagnosis and prevention of thyroid cancer.
Thyroid hormones are regulators of development and metabolism. The lack of concordance of thyroid function and disease in identical twins suggests that environmental effects have a significant role. Quantifying epigenetic modifications, such as DNA methylation, has the potential to identify causal effects from the environment. This research will provide a comprehensive database of DNA methylome alterations that will contribute important insights into thyroid function in health and disease.
