Conologues: Ultra-fast-acting Therapeutic Insulins Based On Cone Snail Venom Insulin Principles

Funding Amount
$1,082,866.00
Summary
The increasing prevalence of Type 1 and Type 2 diabetes demands better treatments. Our Project is based on a fascinating discovery by our international team of CIs of a new type of insulin within marine organisms that could form the basis of a novel diabetes therapeutic. Within our Project we will exploit this discovery to develop a new class of ultra-rapid-acting therapeutic insulins.
Targeting The Insulin And Insulin-like Growth Factor Receptors In Cancer, Diabetes And Alzheimer's Disease

Funding Amount
$993,251.00
Summary
Diabetes, cancer and Alzheimer's disease are three major diseases facing Australia. This Project will investigate a common point-of-focus of these diseases, namely the interaction of insulin and the insulin-like growth factors with their receptor molecules on the cell surface. It will use recent breakthrough findings by the Chief Investigators to develop new therapeutic approaches for these diseases that could function by targeting these interactions.
Structural Events In Insulin And IGF Signalling - A Nanodisc Approach To A Problem In Cancer, Diabetes And Alzheimer's Disease

Funding Amount
$752,403.00
Summary
Insulin and its insulin-like growth factors play a major role in three major disease states facing ageing Australians—diabetes, cancer and Alzheimer's disease. We aim to understand how these proteins send messages into cells via their so-called receptors. We will isolate the receptor molecules from cells and then image them in an advanced electron microscope to produce three-dimensional images. Our findings will have implications for the design of therapeutics targeting the above three diseases.
Targeting RCAN1 To Treat Type 2 Diabetes And Obesity

National Health and Medical Research Council
Funding Amount
$814,468.00
Summary
Obesity and impaired insulin secretion are significant contributors to Type 2 diabetes. In this project we demonstrate that a protein called RCAN1 contributes to both fat mass and insulin secretion and that this contribution is exacerbated in obesity and in Type 2 diabetes. We will identify how RCAN1 controls these major metabolic pathways with outcomes including the development of new therapeutics for obesity and Type 2 diabetes.
Sphingosine Kinase: A Target For Obesity-induced Insulin Resistance

Funding Amount

Summary
Insulin resistance, a characteristic of type 2 diabetes, is linked to abnormal metabolism of lipid (fat) in tissues such as liver and muscle. This project aims to identify a novel pathway which may promote a build up of lipids in liver and therefore leads to the development of type 2 diabetes. This work may provide a basis for understanding and optimizing treatment of insulin resistance by regulating the control of fat metabolism in liver.
Only recently has it emerged that our cells have a built-in backup mechanism that instructs cells to die in extreme cases, such as when viruses have hijacked a cell. A misfiring backup mechanism is thought to underlie a number of human diseases, including inflammatory disease. Our investigation will establish a starting point for the development of novel anti-inflammatory drugs.
Genomic Analysis Of DNA Binding And Gene Regulation By The Chromatin Remodelling Factor UBF

Funding Amount
$624,254.00
Summary
Synthesis of ribosomes, the cellular protein synthetic machinery, is the major anabolic event of a growing cell and is frequently dysregulated during disease such as cancer. This grant will examine a protein termed UBF that we think plays an important role in orchestrating the cellular response to dysregulated ribosome biogenesis. By understanding how UBF functions we hope to uncover novel therapeutic approaches to treat diseases associated with ribosome stress .
Activation Of BMP4 Signalling To Inhibit Breast Cancer Metastasis

Funding Amount
$748,742.00
Summary
The spread of cancer cells to other organs is a common cause of breast cancer-related death in women. Current therapies for advanced breast cancer are often palliative since the secondary tumours become resistant to the chemotherapy. Here, we are using preclinical models of advanced breast cancer to develop a treatment that should be effective in patients with secondary tumours and should reduce the risk of dying of this disease.
The Role Of Meninges In Midbrain Dopamine Development

National Health and Medical Research Council
Funding Amount
$378,311.00
Summary
Dopamine neurons are important for the control of movement, emotion and cognitive function, and are affected in a number of disorders such as Parkinson’s disease. Instrumental in improving our knowledge of disease etiology and the development of new therapies will be a greater understanding of how these cells are initially born during development. This project examines the role of the brain’s meninges in dopamine development and repair and will identify proteins and signaling pathways involved.
Targeting The Sympathetic Nervous System To Reduce The Burden Of Fatty Liver Disease
Funder
National Health and Medical Research Council
Funding Amount
$728,152.00
Summary
The metabolic syndrome is characterised by abdominal obesity, high blood pressure and an increased risk of diabetes development. It is clear from our own observations that the sympathetic nervous system (SNS) is important in the generation of obesity-related illness and, through its stimulation of the liver, plays an important role in the development of obesity-related liver disease. We will target the SNS in order to reduce the burden of obesity-related liver disease.
