The Role Of Nuclear Architecture In The DNA Damage Response

Funding Amount
$561,966.00
Summary
The goal of the proposed research is to understand how dynamic changes to the chromatin genome packaging network, interact with the DNA damage response and gene expression machinery, to repair damaged DNA and the impact this has on cancer biology. To do so we are combining cutting edge molecular biology techniques with innovative novel microscopy methods developed by our research team, that far exceed the spatiotemporal resolution currently used to study chromatin biology.
How Replication Stress Activates The Mitotic Telomere DNA Damage Response To Kill Cancer Cells

Funding Amount
$486,467.00
Summary
We discovered a novel mechanism linking stress during DNA replication to difficulties with the cell division process, and identified how this turns on DNA damage response signals from the chromosome ends (i.e. “telomeres”). We have further identified that we can exploit this mechanism to kill cancer cells. In this project we will explore this newly discovered mechanism and identify how it can be targeted for therapeutic purposes.
Imaging The Hepatitis C Virus Life Cycle In Real-time

$477,504.00
Summary
Hepatitis C virus (HCV) is a serious viral pathogen that causes significant liver disease. This proposal plans to examine how two proteins from the HCV, core and NS5A, interact with host proteins and pathways to facilitate viral replication and release of HCV; two processes that are poorly understood. Specifically we will tag viral proteins to allow us to investigate the HCV life cycle in living cells and determine the role of core and NS5A in facilitating HCV replication. This proposal may unco ....Hepatitis C virus (HCV) is a serious viral pathogen that causes significant liver disease.

Summary
Presently, liver disease from chronic hepatitis C and obesity represents a major health problem. Overall, approximately 50% of Australians with chronic hepatitis C are obese and these patients are at significantly increased risk of rapidly progressing to liver failure. It is now recognized that fat derived factors play an important role in regulating inflammatory responses. This grant proposal aims to gain insight into how liver and fat derived inflammatory factors interact to promote increased ....Presently, liver disease from chronic hepatitis C and obesity represents a major health problem.

Funding Amount
$773,484.00
Summary
This research will use a combination of genomic, biochemical and functional genomics approaches to investigate the role of the atypical mCH form of DNA methylation in neuronal genome regulation and function, and provide new insights into the role of the epigenome in healthy brain function and neural pathologies.
Risk Of Hepatitis C Reinfection Among People With Current Injecting Drug Use Following Successful HCV Treatment

Funding Amount
$2,245,228.00
Summary
In Australia, hepatitis C (HCV)-related morbidity and mortality are rising. One of the most important recent breakthroughs in clinical medicine is the approval of safe, simple, interferon-free HCV therapies with cure rates >95%. Although people who inject drugs account for the majority of new and existing cases of HCV, reinfection following treatment can occur. The goal of this Project Grant is to examine HCV treatment and reinfection following successful therapy among people who inject drugs ....In Australia, hepatitis C (HCV)-related morbidity and mortality are rising.

Epigenetic Changes In The Prostate Cancer Microenvironment

Funding Amount
$848,954.00
Summary
Many men with prostate cancer have slow-growing tumours that are unlikely to spread outside the prostate. These men with low-risk cancer are often monitored to prevent unnecessary aggressive treatments. However, the current methods used to distinguish between slow-growing and aggressive tumours are imprecise and there is a risk of missing aggressive tumours. We aim to identify new biomarkers of prostate cancer by measuring modifications to the DNA in the tumour and surrounding cells
Circulating Tumour DNA To Monitor Treatment Response And Resistance In Chronic Lymphocytic Leukaemia
Funder
National Health and Medical Research Council
Funding Amount
$876,950.00
Summary
Many cancers shed small amounts of DNA (ctDNA) into the patient’s bloodstream and recent advances in genomic technologies now allow levels of ctDNA to be accurately measured in the blood. Changes in ctDNA levels have potential to be used as specific markers of disease progression and/or response to cancer therapy. This project will evaluate if ctDNA can be used to monitor treatment responses and individualise treatment decisions in patients with chronic lymphocytic leukaemia.
SCALE-C: Strategies For Hepatitis C Testing And Treatment In Aboriginal Communities That Lead To Elimination
Funder
National Health and Medical Research Council
Funding Amount
$2,175,170.00
Summary
Prevalence of hepatitis C infection within the Aboriginal population is among the highest of any identifiable population in Australia. Highly effective, direct-acting antiviral (DAA) therapy, and their listing on the PBS in 2016 has revolutionised HCV clinical management in Australia. The SCALE-C study will evaluate an established test and treat model to rapidly scale-up DAA within four Aboriginal communities to determine both impact on community prevalence and ongoing transmission.
