Funding Amount
$696,404.00
Summary
Glioma, the most common adult brain cancer, is incurable. Recent advances now allow us to grow glioma cells directly from patients in the laboratory in a way that preserves the features of the original tumor. In this proposal we will systematically analyze such cells using state-of-the-art technologies to identify new processes important to glioma, which in turn should facilitate the identification of innovative therapeutic approaches.
Regulation Of Ca2+/calmodulin Dependent Protein Kinase Kinase-2 By Phosphorylation

Funding Amount
$570,334.00
Summary
This project will study the regulation of an enzyme called CaMKK2, which plays a pivotal role in controlling a number of important biological functions including brain development, regulation of appetite, energy metabolism and blood pressure. Understanding how this enzyme is regulated may open new avenues for treating Type 2 diabetes, obesity, and cardiovascular disease.
Developing New Therapeutic Strategies For Brain Cancer
Funder
National Health and Medical Research Council
Funding Amount
$763,845.00
Summary
Each year, over 1,500 Australians will develop brain cancer. Unlike many cancers, it cannot be prevented by lifestyle changes. Adults with brain cancer usually die within 2 years. The overall aims of this funding are to extend patients' lives and build brain cancer research in Australia so that we have the best chance of curing this disease. The expected outcome is clinical trial of drug candidates for the most common and most deadly brain cancer, high-grade glioma.
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.
Many of the most serious diseases of Western societies including obesity, Type 2 diabetes, cancer growth and metastasis and cardiovascular disease have metabolic dimensions. The enzyme AMPK regulates cellular and whole body energy homeostasis by coordinating metabolic pathways to balance energy demand with nutrient supply. We are studying the structure and function of AMPK with the aim of better treating metabolic diseases.
Oxidative Phosphorylation Regulation And Neuroprotection In Optic Neuropathies

Funding Amount
$430,231.00
Summary
We have shown clear differences in the mitochodria, cellular organelles that generate energy, between optic atrophy patients who have good vision and those of patients who have poor vision. We believe that these changes represent a compensation mechanisms that preserves mitochondrial energy production and protects optic nerve cells. This study will characterize these differences further with the aim of identfying new treatments for preventing nerve loss and preserving vision.
Targeting The Insulin And Insulin-like Growth Factor Receptors In Cancer, Diabetes And Alzheimer's Disease

National Health and Medical Research Council
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.
The Role Of The AMPK-ACC2 Signaling Axis In Metabolic Control During Exercise And Obesity

Funding Amount

Summary
Australian society is experiencing an epidemic of obesity that is contributing to diabetes, cardiovascular disease and premature death. This project is investigating how exercise might prevent obesity and type 2 diabetes by examining the major pathways that regulate fat metabolism.
A New Function For An Old Enzyme: Src Protein Kinase Directs Excitotoxic Neuronal Death In Stroke
Funder

Funding Amount
$513,975.00
Summary
In our previous investigation of how brain cells die in patients suffering from stroke, we found that stroke causes aberrant activation of an enzyme called Src in the affected brain cells. Furthermore, this aberrantly activated Src directs the brain cells to undergo cell death. Our proposal, which aims to decipher this neurotoxic mechanism of the aberrantly activated Src will benefit development of new therapeutic strategies to reduce brain damage in stroke patients.

Summary
Antibodies are a major component of the bodies immune system that bind (i.e. stick) to foreign substances such as viruses. Once bound, these antibodies can activate other parts of the immune system, which help destroy the foreign substance. Analogous to the situation above, a number of institutions are testing antibodies that bind to cancer cells, in order to determine if they are able to destroy these cells.

Once bound, these antibodies can activate other parts of the immune system, which help destroy the foreign substance. Analogous to the situation above, a number of institutions are testing antibodies that bind to cancer cells, in order to determine if they are able to destroy these cells. It is also possible to generate antibodies that bind to receptors on the surface of cancer cells and block their function. If you target a receptor critical to the growth or survival of a cancer cell in this way, then swtiching-off this signal may inhibit tumor growth. In this proposal we plan to test a panel antibodies that recognize receptors important to the growth of brain cancer. Two of these antibodies have been generated and the other two will be made as part of this proposal. A key aspect of this proposal will be testing these antibodies in combination to determine how many receptors need to be targeted in order to get complete tumor regressions in animal models. Overall this work will help us identify new therapeutic strategies for the treatment of brain cancer. Finally, we will also analyze the way different receptors interact together in brain cancer cells.Read moreRead less
