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.

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.

Breast cancer affects approximately one in ten women and is therefore a major health problem.

In order to improve the diagnosis, treatment and prognosis of this disease, it is critical to understand the genetic defects that contribute to disease initiation and progression. Although a number of breast cancer susceptibility genes have been identified, the contribution each of these genes makes to breast cancer susceptibility is currently unclear. This is partly due to limitations in current diagnostic processes and an incomplete understanding of all of the genetic elements for which disruption can lead to loss of gene function. This proposal aims to identify regulatory pathways that are critical for the expression of an important breast cancer gene called BRCA1. Furthermore, it aims to determine the status of these pathways in breast cancer patients, thus expanding our knowledge of the actual contribution that disruption of this gene makes to this disease. It also aims to determine the potential for trans-acting factors to regulate the expression of BRCA1 and thus activity of the BRCA1 pathway. The predicted outcome of this research is an improved ability to perform presymptomatic diagnostic testing for breast cancer and the ultimately the development of more effective drugs to treat certain breast tumours.Read moreRead less
