Summary
The aim of this project is to elucidate the mechanisms behind the intracellular regulation of nitrogen monoxide (NO) levels, which has broad implications for understanding NO activity in many processes which have major vital health implications, including the cytotoxic of macrophages and the control of blood pressure.
Prevention Of Drug Toxicities With Dichloroacetic Acid - The Implications For Cancer Chemotherapy

Funding Amount
$539,839.00
Summary
Many valuable cancer drugs have limited clinical use because of their toxic side effects. Our experiments with a new anti cancer drug called dichloroacetic acid (DCA) will determine if it can reduce the toxic effects of Cisplatin on the kidney and the effects of Doxorubicin on the heart.
Glutathione Transferase Zeta: A Novel Regulator Of Glucose And Lipid Metabolism

Summary
Obesity is a problem of global significance as a cause of preventable illness and death. The many consequences of obesity including cardiovascular disease, type 2 diabetes, cancer and osteoarthritis are an increasing burden on affected subjects and on the health care system. Our recent studies have revealed a novel pathway for the regulation of obesity. This discovery has provided a new target for the development of drugs for obesity and related disorders.
Investigating The Cellular Response To Iron-Depletion: The Trilogy Of ASK1, Thioredoxin And Ribonucleotide Reductase

$552,572.00
Summary
Iron is crucial for many essential biological processes. Recently, we demonstrated that iron-depletion can affects important signalling pathways (e.g., JNK and p38) that play important roles in growth arrest and apoptosis. This study is designed to investigate the cellular and molecular effects of iron depletion which currently remains unclear. The research is crucial for understanding: (1) the effects of iron deficiency and (2) for understanding the effects of iron chelators that are used for t ....Iron is crucial for many essential biological processes.

Glutathione Transferase Omega 1 As A Novel Target For Sepsis And Other Inflammatory Disorders.

Funding Amount
$694,471.00
Summary
Sepsis is a major clinical problem that causes more deaths in Australia than breast, prostate or colon cancer. The deaths result from an overwhelming systemic inflammatory response to infection. We have discovered that this response is dependent on an enzyme called GSTO1-1 and that inhibitors can block the inflammatory response . In this study we will identify new drug like compounds that can inhibit GSTO1-1 and prevent death from sepsis.
Taking A Break For Brain Health: Interacting Effects Of Exercise Bouts With Breaks In Sitting Time On Cognitive And Cerebrovascular Function In Overweight Adults
Funder

Funding Amount
$775,055.00
Summary
Whether people do or do not exercise or not, there are serious health consequences – including adult-onset diabetes and heart disease – arising from the 7 to 10 hours of sitting that most Australian adults do each day. Exercise helps to delay Alzheimer's disease and other declines in brain function with ageing. This study will test whether, among overweight adults, combining exercise with breaking up prolonged sitting time can improve markers of brain health and mental functioning.
New Cardiac Ryanodine Receptor Inhibitors For The Treatment Of Heart Failure
Funder
National Health and Medical Research Council
Funding Amount
$612,885.00
Summary
We have discovered that a protein that is recognized for its role in phase II detoxification can also modify the calcium signaling that underlies heart function. The small part of the protein that is active in heart tissue differs from the enzyme center that supports detoxification and can thus be used as a therapeutic agent in heart failure and in genetic cardiac conditions. The project is to develop the cardio-active part of the protein for maximum efficacy and for eventual clinical use.
NAD+ And SIRT2 Regulation Of Mitotic Lifespan, Senescence And Healthy Ageing

Funding Amount
$617,274.00
Summary
During youth, cells in our body undergo a continual process of self-renewal, known as mitosis, where cells divide and accurately provide equal number of chromosomes into each daughter cell. During old age, dysfunctional mitosis leads to senescence, where cells no longer divide, and are unable to renew old tissue. We have uncovered a new molecular pathway involving the enzyme SIRT2 that maintains healthy mitosis, and will determine if targeting this pathway preserves health into old age, and ulti ....During youth, cells in our body undergo a continual process of self-renewal, known as mitosis, where cells divide and accurately provide equal number of chromosomes into each daughter cell.

Funding Amount
$554,716.00
Summary
Until there is a cure, breast cancer research must continue to discover new targets for therapy. We have novel insight into a new tumour supressor; FOXP3, and have identified the genes it regulates in T cells. We can now apply this information to normal breast tissues to reveal the mechanism and targets that FOXP3 controls to prevent cancer
Innovative Use Of Hydrogel Technology To Recapitulate And Investigate Cardiac Pathology.

Funding Amount
$716,162.00
Summary
Hypertrophic cardiomyopathy is the leading cause of sudden death in the young. No treatment exists that can reverse or prevent it, primarily because the underlying mechanisms of the disease have not been fully elucidated. I will use innovative hydrogel technology to simulate the disease state. I will use this as a tool to identify the mechanisms involved with development of the disease. This will enable identification of potential therapeutic targets for prevention of the disease.
