Summary
Epilepsy may be due to either one single genetic mutation or a combination of several gene-environment interactions, affecting how ion channels function. It is not possible to directly interrogate channels in the living human brain but, because similar channels are found in peripheral nerve, much may be learned about aberrant channel function from peripheral nerve. This project aims to measure peripheral nerve excitability in epilepsy patients, using it as a marker of the final common pathway of ....Epilepsy may be due to either one single genetic mutation or a combination of several gene-environment interactions, affecting how ion channels function.

Examining The Metabolic And Cognitive Deficits Caused By Insulin Resistance In The Ventral Striatum
Funder
National Health and Medical Research Council
Funding Amount
$400,372.00
Summary
Brain insulin resistance is thought to cause metabolic and cognitive deficits, but the underlying neural mechanisms remain elusive. This project addresses this gap in our knowledge by examining how brain insulin resistance disrupts the metabolic regulation of food intake and the cognitive control of actions. The outcomes will provide new insights in disorders characterised by brain insulin resistance such as obesity and dementia.
EPITHELIAL ION TRANSPORT DEFECTS IN CYSTIC FIBROSIS: PATHOPHYSIOLOGY AND TREATMENT

Summary
The thin layer of fluid covering the surface of the air passages acts to protect the airway surface from drying. This fluid also allows the hair-like projections, or cilia, on the top of the airway cells to beat more effectively. The volume and composition of this fluid is determined by the movement of salt and water across the mucous membranes of the air passages. The importance of this fluid is shown by the problems that occur in Cystic Fibrosis (CF), the most common lethal inherited disease a ....The thin layer of fluid covering the surface of the air passages acts to protect the airway surface from drying. This fluid also allows the hair-like projections, or cilia, on the top of the airway cells to beat more effectively. The volume and composition of this fluid is determined by the movement of salt and water across the mucous membranes of the air passages. The importance of this fluid is shown by the problems that occur in Cystic Fibrosis (CF), the most common lethal inherited disease affecting Australians. In CF, altered salt transport causes drying of the airway surface which impairs the working of the cilia. This leads to retention of mucous in the airway with repeated bacterial infections damaging the lungs. Simple tests have been designed to directly measure the movement of salt across the surface of the nasal passage using a fine soft rubber tube. Movement of mucous in the nose is measured using other simple techniques that are currently used diagnostically. Together, these tests in the nose provide vital information about how the surface of normal human airway moves salt, water and mucous. Any differences found in CF patients will then give us a good idea of the problems found in the CF lung. We will study the interactions between calcium, sodium and chloride in the fluid lining the airways, measuring changes in salt and mucous movement. A range of testing procedures will be used in human volunteers, anaesthetised mice and isolated tissues from sheep. We have already demonstrated important links between the fluid lining the airways and salt movement, and we expect that this may lead to the development of new treatments for Cystic Fibrosis. This therapy will focus on treating the lung problems of CF patients, the major cause of disability. We anticipate that this preventative therapy may offer real benefits in the fight to cure CF.Read moreRead less
Melanotransferrin: A “Missing Link” And A Novel Pharmacological Target For Treatment

Funding Amount
$613,848.00
Summary
Despite >30 years of research, the precise function of the protein, melanotransferrin (MTf), is unknown. However, we have breakthrough evidence that MTf stimulates WNT signalling as a major driver in cancer progression. We will investigate this hypothesis, which will underpin new cancer therapies. Indeed, we designed a new class of drugs that target the WNT pathway via up-regulating the WNT inhibitor, NDRG1. This drug (DpC) inhibits MTf expression to block tumour cell growth and metastasis.
The Structure And Function Of The Apical Domain In Insulin Secreting Beta Cells.

Funding Amount
$571,741.00
Summary
Loss of control of insulin secretion is causal in diabetes and therefore its understanding is a key goal to shed light on the disease. We have recently identified a new domain in the insulin secreting cells, called the apical domain. This proposal will define the role of this apical domain in controlling insulin secretion. The outcomes could provide new insights into how diabetes develops and new targets for therapies.
Improving Linkages For Chronic Disease Prevention In Indigenous Communities: A Quality Improvement Approach.

Funding Amount
$318,768.00
Summary
Primary health care and public health are often conceived as two entities providing complementary services within the health system. This research aims to better understand how to link these complementary services by using quality improvement methods and to identify successful interventions that facilitate these linkages in the prevention of chronic disease in Indigenous communities.
Dual Targeting Of The Androgen Receptor For Effective And Durable Control Of Lethal Prostate Cancer
Funder

Funding Amount
$946,177.00
Summary
Preventing binding of androgens to the androgen receptor is the mainstay treatment for advanced prostate cancer, but resistance inevitably develops and the disease becomes lethal. We will develop a new drug that targets a part of the androgen receptor unrelated to its androgen binding function to overcome resistance to current therapy. As this drug will be effective in all stages of prostate cancer, it has high potential to improve survival outcomes for men with prostate cancer.
Developing Salient Messages For Indigenous Tobacco Control In Rural Aboriginal Smokers

Summary
I am a General Practitioner with a keen interest in smoking cessation particularly for Aboriginal people, who have a high rate of smoking. Media messages are not to date being completely effective in this group, so I am investigating how to make more relevant and persuasive messages to support Indigenous smokers and their families (importantly pregnant smokers) to become smoke-free and encourage them to use effective treatments to do so.

The principle of respect for autonomy is a guiding ethical principle in a range of areas, including in medical and legal contexts, for example in requirements regarding informed consent, and in ethical guidelines governing protocols for research involving human subjects. A better understanding of autonomy and its relationship to the social context has the potential to produce indirect socio-economic benefits by informing theory and practice in these and other areas.
