Summary
Epilepsy is a disease which affects 2-4% of the population. There are a wide range of drugs available to treat the condition but there is consistently 30-40% of patients who do not respond well to any of these drugs and who continue to have seizures. The reason that there are no drugs available for these people is that most of the drugs available have been designed along the same principles. A new set of principles is needed to develop new drugs which will be able to treat those people not respo ....Epilepsy is a disease which affects 2-4% of the population. There are a wide range of drugs available to treat the condition but there is consistently 30-40% of patients who do not respond well to any of these drugs and who continue to have seizures. The reason that there are no drugs available for these people is that most of the drugs available have been designed along the same principles. A new set of principles is needed to develop new drugs which will be able to treat those people not responding to current therapy. This project is designed to identify new biologic pathways which may be interrupted with drugs to prevent seizures in people with epilepsy. This project uses a procedure to induce mutations into genes in mice and then screens for mice which do not seize when challenged with a drug which generates seizures in mice. Genetic studies will identify the mutated genes and these will be used as potential targets for new therapies or will identify new biological pathway which should expand the use of future anti-epileptic drugs.Read moreRead less
Predicting Drug-drug Interactions Due To Tyrosine Kinase Inhibitors: Inhibition Of Drug Metabolising Enzymes And Transporters

Funding Amount
$535,495.00
Summary
Tyrosine kinase inhibitors (TKIs) are a new class of anticancer agents. Cancer patients typically receive multiple drugs, for the treatment of cancer and other diseases, increasing the probability of interactions between coadministered drugs. Despite the widespread use of TKIs, their potential to cause drug interactions is poorly understood. Using novel in vitro approaches, this project will identify drug interactions precipitated by TKIs thereby improving drug efficacy and patient safety.
A Novel Metabolic Role For UDP Glycosyltransferase 8 (UGT8)

Summary
The UDP glycosyltransferases (UGTs) are a family of enzymes that remove drugs and toxins from the human body as well as control levels of naturally produced molecules such as bile acids and hormones. We found that a new member of this family called UGT8 processes bile acids in the kidney and intestine and can affect how bile acids act to regulate metabolism. Our studies uncover new roles for bile acids in liver, kidney and gut health and in metabolic disorders such as diabetes and obesity.
Structure And Function Of Antimicrobial Therapies And Their Interaction With Upper Respiratory Biofilms

Funding Amount
$320,891.00
Summary
Bacterial infections of the upper respiratory tract are a major public health problem affecting millions of Australians. Commonly prescribed antibiotics are often not able to eradicate all bacteria as the bacteria often reside in a protective, self-produced gel-like matrix known as biofilm. This Fellowship aims to unravel the interaction of modern anti-infective therapeutics with the biofilm for the development of the next generation of safe and efficacious anti-biofilm strategies.
Targeting RCAN1 To Treat Type 2 Diabetes And Obesity

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.
Topical peptide delivery for cosmetic and therapeutic benefits. Milk is a major Australian agricultural commodity and is now used in a number of topical products for the management of various skin conditions including chafing in babies, eczema and ageing skin. Hence, this work hopes to contribute to promoting and maintaining good health of Australians.

Milk is a major Australian agricultural commodity and is now used in a number of topical products for the management of various skin conditions including chafing in babies, eczema and ageing skin. Hence, this work hopes to contribute to promoting and maintaining good health of Australians.
In addition, there is considerable research being conducted on peptide development for a range of diseases and there may be a possibility of delivering these by the skin.
This work, in seeking to understand some of the fundamental determinants governing how exogenously applied peptides distribute in the skin, is also contributing to the development of Australian pharmaceutical and cosmetic industries.Read moreRead less
Stimulant laxatives are widely used and usually very effective in the short term, but how they work is very poorly understood. Our recent work has shown that they selectively excite sensory pathways from the colon which then trigger defaecation. This points to an undiscovered mechanism that potently affects colonic sensation and motility. This is likely to be a target for new treatments for other colonic disorders such as Irritable bowel syndrome and faecal incontinence.
Irritable Bowel Syndrome (IBS) is one of the leading causes of chronic pain both world-wide and in Australia for which there is a lack of treatments. Chronic pain arises from nerve fibres in the colon wall, which fail to 'reset' back to normal following inflammation. Targeting these nerve endings with drugs is a key advance in IBS treatment. This project will identify selective oxytocin analogues that act in the colon to lower pain in sensory nerves thus providing efficacious pain relief in IBS.
