Summary
Recent studies have identified DNA sequence variations within the human genome that are associated with an increased risk or can influence the outcome of breast cancer. This research program will identify the key genes affecting cancer development and assess their contribution to cancer growth. I will then use this knowledge to assess their suitability for drug development. Understanding how our DNA contributes to breast cancer will provide new avenues for prevention or treatment.
Clinical Classification Of Regulatory Variants In Breast Cancer Susceptibility Genes

Funding Amount
$536,966.00
Summary
Variations in our genes can confer a risk of diseases including breast cancer. Determining the clinical significance of these variations is a major and increasing challenge for genetic counselors and clinicians. This project will evaluate the clinical significance of variants in the control regions of breast cancer susceptibility genes. This research will inform the development of guidelines for interpreting such variants in a clinical setting.
Understanding The Regulation Of The Location Of Chromosomes Within The Nucleus

Summary
The nucleus of each human cell, despite being under 10µM in diameter, contains 46 chromosomes, each consisting of several centimeters of DNA. The organisation of chromosomes within the nucleus helps regulate which genes are switched on and off. Genes attached to the nuclear lamina, which lines the nuclear membrane, tend to be switched off. Mutations in the nuclear lamina cause several diseases, including progeria, resulting premature aging. I am interested in understanding why only certain regio ....The nucleus of each human cell, despite being under 10µM in diameter, contains 46 chromosomes, each consisting of several centimeters of DNA.

Nuclear Retention-and-release Of RNA: A Naturally-occurring Mechanism For Controlling Gene Expression

Funding Amount
$428,753.00
Summary
The deliberate retention of messenger RNA in the nucleus is a newly-discovered biological mechanism used by cells to control which genes are made into proteins, and when. This is a fundamental process in health and disease. The project will employ cutting edge molecular and cellular techniques to discover the principles underpinning nuclear retention. These insights will allow the development of new methods to spatially and temporally control gene expression in diverse gene therapy applications.
Post-GWAS Functional Characterisation Of Breast Cancer Susceptibility Loci

Funding Amount
$764,632.00
Summary
Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer. Several of these regions do not contain any known genes, suggesting that regulatory DNA sequences are responsible for the associated risk. The aim of this proposal is to identify and characterise these DNA sequences. Understanding how sequences variations in these regions contribute to breast cancer will provide novel avenues for therapy.
High-throughput Identification And Evaluation Of New Breast Cancer Genes From GWAS.

National Health and Medical Research Council
Funding Amount
$841,075.00
Summary
Recent studies have identified DNA markers within the human genome that are associated with an increased risk of breast cancer. Most of these markers are located in noncoding regions, therefore the key genes driving risk are not known. This proposal will identify the target genes at all breast cancer risk regions and assess how specific markers affect disease risk. Understanding how DNA variation contributes to breast cancer will provide new avenues for prevention or treatment.
The Structure And Organization Of The Mitochondrial Genome In Health And Mitochondrial Disease

Funding Amount
$553,646.00
Summary
Mitochondrial DNA (mtDNA) mutations and mitochondrial dysfunction have been associated with a wide range of multi-system human diseases, although much remains to be learnt about molecular mechanisms in the pathogenesis of these diseases. Our goal is to understand how the expression of the mitochondrial DNA is regulated by mtDNA-binding proteins that will allow us to provide important insights into the molecular mechanisms of mitochondrial diseases.
Molecular Insights Into Long Noncoding RNA-protein Complexes: Important Gene Regulators In Cancer
Funder
National Health and Medical Research Council
Funding Amount
$388,927.00
Summary
Cancer cells turn good genes off and bad ones on: but how do they do this? Recent breakthroughs suggest that noncoding RNA, produced from so-called ‘junk’ DNA, is important. One such noncoding RNA forms paraspeckles, a novel component of the cell machinery. Here, we will pick apart the way paraspeckles are organised and function, to develop them as a prototype for designing anti-cancer treatments against noncoding RNAs.
Functional Characterization Of The Regulatory Architecture Of Melanoma-associated Loci

Funding Amount
$645,663.00
Summary
Melanoma accounts for more than 75% of skin cancer related deaths. In Australia, >10,000 new cases are diagnosed yearly. In this proposal, we will apply novel genetic sequencing technologies developed in our laboratory to examine genomic regions that are associated with melanoma development. By focusing on selected areas, we will obtain a much deeper understanding of how these genes are regulated and find new ways of detecting and treating this disease.
