Nuclear architecture is critical to the preservation of genome integrity. The aim of this research proposal is to delineate the role of chromatin organisation in transcription factor target search and damage site recruitment of DNA repair factor machinery. To achieve this I have developed fluorescence microscopy methods to monitor changes in chromatin structure with submicron resolution. Only with this technology can I determine how chromatin dynamics maintain genome integrity or induce disease.
Female fertility and age at menopause are determined by the number and quality of eggs stored in the ovaries. For unknown reasons, two-thirds of all eggs die soon after they are made. Furthermore, a serious side effect of cancer treatment is egg death resulting in infertility and early menopause. I am unravelling the genes involved in determining whether an egg will live or die. This understanding will help us develop novel strategies to preserve fertility during aging and cancer treatment.
Modulating Skin Regenerative Responses To Improve Wound Repair And Fight Carcinogenesis

Summary
Skin disorders, such as hard to heal wounds or the most common skin cancers, are a major burden on the national health system. Despite their different nature they employ similar mechanisms of response to injury. In this project we intend to develop a comprehensive understanding of the genetic and molecular mechanisms at play to allow clinical interventions to prevent or to cure these disorders.
Fetal Cardiovascular Development And The Impact Of Chronic Hypoxia And Fetal Growth Restriction

Funding Amount

Summary
Low birth weight occurs in 7% of Australian babies and is associated with an increased risk of cardiovascular disease in adult life. Understanding the mechanisms underlying heart and blood vessel development in low birth weight babies will lead to improved identification and intervention in those individuals at risk of cardiovascular disease in adult life, improving heart health for Australians. Reducing cardiovascular disease will improve both quality and quantity of life for Australians.
Coordination Of The Fanconi Anemia Pathway To Maintain Genome Stability

Summary
Fanconi anaemia is a heritable disorder where bone marrow failure occurs on average at age seven and is the major cause of death at around age 20. Many patients also develop leukaemia, representing another overwhelming hurdle in their youth. The incorrect function of any one of 19 proteins can lead to Fanconi anaemia. We will search for a drug that can compensate for the absence of one of these proteins to allow correct function of the other proteins offering possible leads for treatment.
Using Human 3D Engineered Heart Tissue For Discovery Of Novel Biology And Novel Therapeutics

Funding Amount
$425,048.00
Summary
The goal of this project is to develop a model of miniaturised 3D human heart tissue for research into cardiac biology and also drug discovery applications. This will hopefully result in better, cheaper drugs in the future with less reliance on animal testing.
Role Of Non-Invasive Imaging Using Speckle Tracking Echocardiography In The Identification And Treatment Of Patients At Risk Of Arrhythmias And Consequent Sudden Cardiac Arrest

Funding Amount
$437,034.00
Summary
Every year, 15,000 Australians die from sudden cardiac arrest. Identifying individuals at risk is a major challenge. We will investigate whether a heart ultrasound technique called speckle tracking allows clinicians to rapidly identify changes in heart muscle that are associated with cardiac arrest. If found to be positive, the technique may be broadly applied to large populations, identifying at risk individuals, potentially rescuing them before cardiac arrest occurs.
