Summary
Over time our cells accumulate damage to their DNA, which introduces mistakes in the genetic code. These mistakes can alter genes that regulate cell growth and survival and, in this way, they begin the process of turning a normal cell into a cancer. This research is investigating the cellular repair mechanisms that safeguard against DNA damage. Manipulating these repair mechanisms may offer a new way to treat cancer, by selectively inducing DNA damage within cancer cells.

Summary
The number of men diagnosed with prostate cancer varies substantially between races, indicating a role of genetics in prostate cancer development. Recently, genetic variations in the PSA gene have been related to prostate cancer risk. I aim to elucidate the molecular mechanism of this correlation and to systematically investigate the association of other novel genetic variations in PSA and related genes with prostate cancer risk in a search of sensitive clinical biomarkers for prostate cancer di ....The number of men diagnosed with prostate cancer varies substantially between races, indicating a role of genetics in prostate cancer development.

Identification Of Genes Responsible For Familial Predispositions To Haematological Malignancies

Summary
A successful approach to the identification of cancer genes has been to study the 5-10% of cases that occur in families with an inherited predisposition to develop cancer. In contrast to solid tumors, few cancer-causing germ-line mutations have been identified for hematological cancers. We are using cutting edge technologies to identify blood cancer genes in a collection of both Australian and international families and comparing them to similar sporadic cancers.
This study will address the idea that cancer commonly involves a genetic pathway that is normally used by stem cells to proliferate in an undifferentiated state. We have evidence to indicate that this system is active in cancer cells and believe this could explain how cancer cells manage to divide rapidly in a primitive state. This project may bring a new perspective to the study of malignant transformation and has the potential to reveal multiple new targets for cancer therapy.
Somatic Retrotransposition Drives Neoplastic Mutagenesis In Glioblastoma Multiforme

Summary
Retrotransposons are mobile genes that copy-and-paste themselves in our genome. Previously thought to represent “junk DNA”, retrotransposons are increasingly found to play major roles in biology. In a recent landmark publication in Nature, we demonstrated that retrotransposons move in the healthy human brain. In the current study, we will use cutting-edge technologies to determine whether brain cancer can occur as a result. This will provide new perspectives of the genetic basis for cancer.
Circulating Tumour DNA As A Noninvasive Biomarker In Melanoma

Funding Amount
$1,299,114.00
Summary
The expanding repertoire of treatment options in melanoma is bringing into focus the need for improved ways to accurately monitor treatment responses and guide treatment decisions. Many cancers shed small amounts of DNA (ctDNA) into the bloodstream and changes in ctDNA levels have potential to be used as specific markers of response to cancer therapy. This project will evaluate if ctDNA can be used as a form of ‘liquid biopsy’ to guide treatment decisions in patients with melanoma.
Molecular Determinants Of Susceptibility And Progression In Breast Cancer

Summary
Breast cancer is heterogeneous, making management a challenge. High-grade cancers including the ‘basal’ type are aggressive, often found in young women and have a propensity for distant spread. They are also associated with a BRCA1 gene mutation. We will study mechanisms that predispose some women to develop breast cancer, the process that allows cancers to grow at distant sites such as the brain and lungs, and how DNA repair proteins are implicated. This will allow development of new diagnostic ....Breast cancer is heterogeneous, making management a challenge.

Defining The Genomic And Therapeutic Landscape Of Familial Breast Cancer

Funding Amount
$1,146,096.00
Summary
As a cancer develops it accumulates alterations (mutations) in its DNA. Some of these alterations lead to enhanced tumour growth, whilst others provide insight into normal processes that have gone wrong to enable the tumour to arise. We will use DNA sequencing and mathematical approaches to characterise these alterations and to identify therapeutic targets in breast tumours arising in patients with an inherited predisposition to develop cancer.
