Summary
Based on our pilot data we postulate that glucose derived molecules such as methylglyoxal (MGO) have effects on inflammation and oxidative stress leading to accelerated atherosclerosis in diabetes. Our studies aim to identify novel treatments which block these effects thus leading to superior protection and prevention of atherosclerosis in diabetes.

This first of a new generation of ultra-sensitive analytical mass spectrometers for small molecules will be established as a national assay facility allowing all Australian researchers open access to a new dimension of highly accurate and simultaneous measurements of multiple bodily chemicals such as steroids, vitamins and hormones. It is crucial to developing new knowledge in basic, developmental and pathological cell biology and for underpinning commercial developments of new molecular targets for therapeutic drugs for many diseases including cancer, cardiovascular disease and reproductive disorders. This facility is pivotal to maintaining international competitiveness in many areas of biological research in national priority areas.Read moreRead less
Epigenetic Determinants Of Nephropathy In Adults With Type 1 Diabetes

Summary
The prevention and successful management of diabetic complications are issues of utmost importance for the health of Australians. We hypothesize that epigenetic pathways partly determine why some individuals with diabetes develop complications of their disease, while others do not, despite a similar duration of diabetes, treatment intensity and mean glucose exposure.

Summary
Estrogen-mediated regulation of gene expression via transcriptional and translational control: complementary, synergistic or opposing responses? Hormones dictate cellular behaviour by activating pre-programmed responses. The sex hormone estrogen affects cell fate by regulating the gene expression, but it is unknown to which extent this response occurs via activation of genes or control of already transcribed gene. The project will investigate how the cell integrates the complex estrogen signals.
The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will ....The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will be the first to comprehensively advance our understanding of the unique role of sex hormones in shaping the adolescent female brain. It will provide critical understanding of how individual differences in hormonal factors increase risk for emotional problems in females, and inform treatment strategies.Read moreRead less
Targeting TGF-beta proteins to control animal reproduction. This project aims to develop a suite of novel biologics to control fertility in female mammals. This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide ....Targeting TGF-beta proteins to control animal reproduction. This project aims to develop a suite of novel biologics to control fertility in female mammals. This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide a non-surgical method of contraception in companion/feral species, which should address the large unmet need for fertility control in these animals.

The critical role of kisspeptin/neurokinin/dynorphin (KNDy) neurons in gonadotropin releasing hormone (GnRH) release. The brain controls fertility through the secretion of its primary stimulatory factor, gonadotropin releasing hormone (GnRH). Brain cells producing three key peptide hormones, kisspeptin, neurokin B and dynorphin (termed KNDy cells) are vital for the control of GnRH. This project will detail the role of KNDy cells in puberty and reproduction.

Defining how gut bacteria regulate metabolism: a role for gut serotonin. This project aims to understand how serotonin-producing cells in the gut interact with gut bacteria (the microbiome), using a combination of cells in culture and live germ-free and genetically modified mice. This project expects to generate new knowledge regarding cellular interactions that underlie important physiological pathways, such as the control of blood glucose and fat storage. The intended outcomes of this project ....Defining how gut bacteria regulate metabolism: a role for gut serotonin.

This project expects to generate new knowledge regarding cellular interactions that underlie important physiological pathways, such as the control of blood glucose and fat storage. The intended outcomes of this project are to identify how gut bacteria communicate with serotonin-producing cells to regulate metabolism, and whether diet acts via a gut microbiome-serotonin axis to impact physiology. The expected benefit of this project will be to provide a new understanding of highly complex physiological systems that regulate our health.Read moreRead less

Summary
This Program brings together four of Australia’s top type 1 diabetes clinical and lab-based research teams. The program has three intersecting themes. The first theme, pathogenesis, focuses on early life and understanding why type 1 diabetes develops. The second theme, prevention, seeks to identifying new drugs to stop the disease from occurring. The third theme, treatment, aims to improve therapies to replace the cells that are destroyed during the disease process.

Summary
Male sex hormone or androgen deficiency (AD) is a common, but under-diagnosed condition. AD decreases well being and contributes to muscle weakness, bone fragility and weight gain. Cutting edge technology will be used to help explain how AD may relate to these negative effects, particularly on muscle function. Given the importance of aging, frailty, osteoporosis and obesity, understanding the role of hormones in these conditions may have major implications for prevention and treatment.
