Summary
Chemotherapy treatment and the natural ageing process leads to ovarian failure and infertility. For young cancer survivors, chemotherapy induced infertility is devastating, and like aged women, leads to hormonal changes that lead to osteoporosis, diabetes, obesity, and neurodegeneration. Here, a new class of molecules will be tested for their ability to prevent and reverse infertility folllowing chemotherapy treatment, and in old age. These findings will improve the healthy lifespan of women.
Structural And Functional Analysis Of A Cancer-linked Co-regulator Complex

Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
Investigating Post-transcriptional Gene Regulation In Cancer

$645,205.00
Summary
In this program, I will enhance our understanding of cancer gene regulation and provide novel avenues for the treatment of aggressive tumours. Using own data and that from collaborators, I will determine patterns of gene regulation in blood cancers and identify markers that predict disease outcome. I aim to understand how gene regulation can transform healthy cells into tumour cells and whether personalised treatment can kill tumour cells more effectively and prevent relapse and metastasis.
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.

Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide. The molecular and cellular processes underlying atherosclerosis, vascular injury and thrombosis are highly complex and not well understood. A multifaceted approach is needed to effectively address these key challenges. This Program brings together world experts in these areas to interrogate gaps in our basic understanding of CVD, and to develop novel therapies for CVD patients by exploiting ....Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide.

A multifaceted approach is needed to effectively address these key challenges. This Program brings together world experts in these areas to interrogate gaps in our basic understanding of CVD, and to develop novel therapies for CVD patients by exploiting new knowledge through integrated research.Read moreRead less
Links between DNA replication and chromosome end maintenance. This project aims to increase knowledge of the way in which cells maintain their genomes, including the ends of their chromosomes, to enable their own survival. The ends of chromosomes (telomeres) are essential for survival and proliferation of the cells of most organisms. This project aims to determine the molecular details of a recently discovered link between telomere maintenance and the way cells maintain the integrity of their ge ....Links between DNA replication and chromosome end maintenance. This project aims to increase knowledge of the way in which cells maintain their genomes, including the ends of their chromosomes, to enable their own survival. The ends of chromosomes (telomeres) are essential for survival and proliferation of the cells of most organisms. This project aims to determine the molecular details of a recently discovered link between telomere maintenance and the way cells maintain the integrity of their genome. This is likely to lead to increased understanding of the fundamental biological process of genome maintenance, representing a significant scientific advance. The project expects to have far-reaching implications for biotechnology applications that require the survival of cells.Read moreRead less
Understanding Mitotic Telomere Deprotection. This project aims to study telomeres, the DNA and protein structures that protect chromosome ends. During cell division, cells under stress intentionally uncap their telomeres. This project expects to generate new knowledge that challenges the conventional notion of telomeres as static elements, showing instead that telomeres can be dynamic signalling hubs. Expected outcomes of this project include an understanding of the genetic, proteomic, and signa ....Understanding Mitotic Telomere Deprotection.

This project expects to generate new knowledge that challenges the conventional notion of telomeres as static elements, showing instead that telomeres can be dynamic signalling hubs. Expected outcomes of this project include an understanding of the genetic, proteomic, and signalling pathways involved in this novel phenomenon. This should provide significant benefits to our fundamental understanding of biological processes that protect human genomes and provide a valuable dataset for research on telomere biology, DNA repair, and genome stability.Read moreRead less
Targeting PI3K-regulated Small Non-coding RNAs To Restore Cardiac Function

Summary
Heart failure affects approximately 2.4% of the adult population and over 11% of people over 80 years old. The majority of existing therapies slow, rather than reverse heart failure progression. The primary goal of this study is to determine whether regulating novel regulatory genes can enhance cardiac function in a setting of heart failure. Ultimately, technologies that target these genes may lead to innovative pharmacotherapies in the clinical management of heart failure.
Shallow water carbonate sediment dissolution in the global carbon cycle. Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead ....Shallow water carbonate sediment dissolution in the global carbon cycle. Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead to an additional uptake of atmospheric carbon dioxide into the global ocean, maybe some additional buffering against ocean acidification, but unfortunately, maybe also a loss of carbonate ecosystems. The outcomes of this project will make a significant contribution to our understanding of the global carbon cycle.

How does the chromatin remodeller CHD4 regulate gene expression? The mechanisms that determine how genes are switched on and off in different tissues and at different times are in many ways still mysterious. It is well established that gene expression patterns in complex organisms are determined in part by the manner in which DNA is physically packaged. Our aim is to define new aspects of these mechanisms that revolve around molecular motors that regulate DNA packaging. This foundational knowled ....How does the chromatin remodeller CHD4 regulate gene expression?

It is well established that gene expression patterns in complex organisms are determined in part by the manner in which DNA is physically packaged. Our aim is to define new aspects of these mechanisms that revolve around molecular motors that regulate DNA packaging. This foundational knowledge will deepen our understanding of gene regulation in all complex organisms and will inform future efforts to rationally modulate gene expression patterns in agriculture, research and other important areas.Read moreRead less
