Defining the molecular and cellular mechanisms of beta cell dysfunction. This project will investigate the influence of environment in the functional adaptation and maladaptation of pancreatic beta cells in diabetes. The research will define the molecular and cellular mechanisms linking environmental triggers such as obesity, high fatty acid levels and hyperglycaemia to beta cell dedifferentiation and dysfunction.

Summary
The Juvenile Diabetes Research Foundation Australian Type 1 Diabetes Research Network and Program. This Proposal continues the development of the initial Type 1 Diabetes Clinical Research Network (CRN), launched by JDRF in June 2011 with a $5m grant from the Australian Government.
The principal goal of the CRN is to positively impact the life of people with T1D in Australia through the support and promotion of clinical research. A further electoral commitment of $35m over 5 years will enable f ....The Juvenile Diabetes Research Foundation Australian Type 1 Diabetes Research Network and Program. This Proposal continues the development of the initial Type 1 Diabetes Clinical Research Network (CRN), launched by JDRF in June 2011 with a $5m grant from the Australian Government.
The principal goal of the CRN is to positively impact the life of people with T1D in Australia through the support and promotion of clinical research. A further electoral commitment of $35m over 5 years will enable further progress towards finding a cure for T1D, including delivering better and faster access to new therapies and treatments that can help prevent and manage the disease.

Novel therapies to limit renal fibrosis in diverse models of renal disease. Kidney failure is a devastating health, social and financial outcome for the individual, their employer, family and the broader society, This project will carefully dissect mechanisms underpinning the scarring in the kidney that predisposes to kidney failure and will investigate novel therapies to prevent kidney damage.
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
Understanding the vesicle release mechanisms that regulate peripheral serotonin levels. The purpose of this project is to understand how serotonin is released into the circulation from specialised cells within the gut. As circulating serotonin controls multiple biological systems within the gut and throughout the body, the outcomes of this project will further understandings of the systems controlling essential bodily functions.
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.
Gene therapy for islet transplantation. Improved understanding of aetiology of type I diabetes. Development of islet transplantation as a clinical therapeutic for type I diabetes. Improved efficacy of islet transplantation. Improved health for subjects with type I diabetes. Decreased diabetic complications. Improved quality of life for subjects with type I diabetes. Reduced burden on health system for management of diabetic complications for subjects with type I diabetes
Development of natural herbal medicines for managing metabolic syndrome in order to prevent type 2 diabetes. Type 2 diabetes affects almost 7% of Australia~{!/~}s population. Its incidence continues to grow, as indicated by high rates of metabolic syndrome, a pre-stage of type 2 diabetes. Using novel and bio-molecular techniques, we will evaluate the effects and mechanisms of three natural compounds from anti-diabetic Chinese herbs on cellular and rodent models with metabolic syndrome. This stud ....Development of natural herbal medicines for managing metabolic syndrome in order to prevent type 2 diabetes. Type 2 diabetes affects almost 7% of Australia~{!/~}s population. Its incidence continues to grow, as indicated by high rates of metabolic syndrome, a pre-stage of type 2 diabetes. Using novel and bio-molecular techniques, we will evaluate the effects and mechanisms of three natural compounds from anti-diabetic Chinese herbs on cellular and rodent models with metabolic syndrome. This study will provide scientific evidence as to how and why herbal compounds improve insulin resistance and abnormalities in glucose and lipids metabolism. The outcome of this project will support the development of natural products to manage metabolic syndrome and prevent type 2 diabetes.

Size matters, but at what cost? Role of male sex hormones in the placenta. This project aims to understand molecular pathways regulated by male sex hormones in the placenta that may contribute to sex-specific fetal growth and survival outcomes in response to reduced oxygen and/or glucose. Through this project, we expect to generate new knowledge of the mechanisms that drive sex-specific placental molecular function using interdisciplinary approaches. The application of this advanced understandin ....Size matters, but at what cost? Role of male sex hormones in the placenta. This project aims to understand molecular pathways regulated by male sex hormones in the placenta that may contribute to sex-specific fetal growth and survival outcomes in response to reduced oxygen and/or glucose. Through this project, we expect to generate new knowledge of the mechanisms that drive sex-specific placental molecular function using interdisciplinary approaches. The application of this advanced understanding of the sex-specific regulation of placental molecular function and fetal growth may be targeted in future studies to improve fetal growth outcomes in placental mammals such as livestock, domestic pets, and humans.Read moreRead less
Estrogen signalling in gonadotropes. Estrogen action is a normal prerequisite for cyclic function of reproduction in the female, but little is known about how this important hormone acts in the relevant cells of the pituitary gland (gonadotropes). In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studi ....Estrogen signalling in gonadotropes. Estrogen action is a normal prerequisite for cyclic function of reproduction in the female, but little is known about how this important hormone acts in the relevant cells of the pituitary gland (gonadotropes). In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studies to investigate the effects of drugs that affect estrogen action and environmental estrogens.
