Ubiquitin And SUMO DNA Damage Response Signalling At Deprotected Telomeres During The Cell Cycle

Summary
Following genome damage cells stop the cell division process and initiate DNA repair. We discovered that at specific times during cell division his does not happen if the damage signals originate from the chromosome ends (i.e. “telomeres”). We anticipate this is necessary to prevent genomic instability in healthy cells and may be driving genomic instability in cancer cells. Experiments described here will elucidate the molecular mechanisms and biological significance of our observation.
Investigating The Cellular Response To Iron-Depletion: The Trilogy Of ASK1, Thioredoxin And Ribonucleotide Reductase

Funding Amount
$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.

Evaluation Of Molecular Mechanisms Driving Metastasis Using Integrated Intravital Imaging

Funding Amount
$885,271.00
Summary
Metastasis is the leading cause of cancer-associated death. Understanding key steps that drive the spread of cancer is critical to improve current treatment strategies. Using cutting-edge imaging technology and 3-dimensional model systems that mimic the disease, we will pinpoint key events that are susceptible to drug intervention and identify new therapeutic targets.
Community-wide Active Case Finding For Tuberculosis

Funding Amount
$3,422,325.00
Summary
During 2010, 8.8 million people developed TB and 1.45 million people died due to the disease. In this project, which will be conducted in Vietnam, one of the countries in our region with a particularly high prevalence of TB, we will test a new form of an old intervention: community-wide screening for TB, not with x-rays but by testing sputum. If the project is successful it has the potential to lead to a giant leap forward towards the elimination of TB as a global health problem.
A Transmission-Blocking Vaccine To Prevent Toxoplasmosis

Funding Amount
$850,225.00
Summary
Toxoplasma gondii causes a globally important zoonotic disease. It is transmitted by cats, and finds its way into our food chain via infected meat and contaminated water. We have used a unique functional genomics pipeline to discover proteins crucial for reproduction of Toxoplasma in the cat. We will now test combinations of these proteins to immunise cats and prove that we can develop a vaccine that blocks transmission of this highly significant parasitic disease.
Defining The Molecular Effectors Of Gene/environment Interaction On Mouse Heart Development

Funding Amount
$749,271.00
Summary
One third of all birth defects involve the heart, and are the most common cause of infant death. Some defects are due to genetic factors, but others arise when the pregnant mother is exposed to environmental stress. We will examine how one stress (low oxygen levels) causes abnormal heart formation in the embryo, look at what causes this at a molecular level, and explore if such stress increases the risk of heart defects in families with a history of such abnormalities
Group A Streptococcal Human Challenge Study: Accelerating Vaccine Development

Funding Amount
$2,018,741.00
Summary
Infection with group A streptococcus (GAS) is a major cause of morbidity and mortality worldwide, including in the Aboriginal population of Australia. Concerted efforts for vaccine development have been hampered by the absence of a suitable animal model. To address this critical knowledge gap we propose to develop a controlled human infection model of GAS infection. This model will provide a direct pathway for the future appraisal of novel GAS vaccines.
How Does Paternal Obesity Influence Offspring Glucose Tolerance?

Funding Amount
$503,398.00
Summary
Obesity and diabetes are closely related to these conditions in either parent, but how the father contributes is unclear. We have shown that normal females mated with obese fathers consuming high fat diet, produce offspring who develop glucose intolerance and impaired insulin secretion. This work will examine the mechanisms underlying this effect in the rat, testing a novel role for environmental factors in the father on disease in offspring that may be relevant to the growing obesity epidemic.
Understanding Sphingolipid Mediators Of Insulin Resistance

Funding Amount

Summary
Sphingolipids are a class of lipid metabolites that have a variety of functions within cells. It has been known for some time that an accumulation of excess lipid, including certain sphingolipids, can adversely impact insulin action and glucose metabolism in cells. In this project we will a combination of strategies to test the hypothesis that the sphingolipid profile can be manipulated to have favourable effects on metabolism.
Developmental Schizotypy In The General Population: Early Risk Factors And Predictive Utility.

Funding Amount
$830,952.00
Summary
This study will determine early childhood risk factors for psychosis-proneness in children aged 11 years, and emerging signs and symptoms of mental health disorders of these children, using population data from the NSW Child Development Study. Determining risk for psychosis as early as possible in the life course will enable the provision of preventative interventions to children at critical points in development.
