Summary
We have discovered that a pathway used to fight viral infections can be triggered to produce massive cell death in the mammary gland. We hope to be able to trigger this response in breast cancers through the strategic combination of available drugs. If successful this project will establish a new therapeutic strategy for breast cancer.
FOXP3 Regulated MicroRNAs: A Novel Component Of FOXP3 Tumour Suppressor Function In Breast Epithelial Cells.

Funding Amount
$554,716.00
Summary
Until there is a cure, breast cancer research must continue to discover new targets for therapy. We have novel insight into a new tumour supressor; FOXP3, and have identified the genes it regulates in T cells. We can now apply this information to normal breast tissues to reveal the mechanism and targets that FOXP3 controls to prevent cancer
Clinicopathological Characterisation Of Male Breast Cancer

Funding Amount
$113,322.00
Summary
Male Breast Cancer is an uncommon and poorly understood disease. Due to its low frequency, there is a paucity of studies with large numbers of patients. Our aim will be to establish one of the largest worldwide databases of Male Breast Cancer. This will allow us to more thoroughly investigate clinical, pathological and molecular characteristics of male breast cancer, improve treatment of these patients and potentially develop novel and innovative strategies for treatment of female breast cancer.
A Functional In Vivo ShRNA Screen For Regulators Of Breast Cancer Metastasis.

Summary
Breast cancer is generally incurable if detected after the tumour has spread to other organs. The genes driving the tumour cells to other sites have not been clearly resolved. This project aims to accelerate the discovery process by using a genome wide functional screen to identify genes that control the spread of breast cancer. If successful, this project could lead very quickly to identification of genes that might be good targets for new therapy against advanced breast cancer.
The Transcription Factor ZNF652: Deciphering Its Role In Breast Cancer.

Funding Amount
$342,996.00
Summary
From our continuing research we have shown a protein called ZNF652 is involved in cancer. This proposal focuses on the role of this gene in the spread of cancer within the breast and to other organs. We will determine its role in a process where a cancer cell changes its characteristics to make it more likely to spread to other tissues. Our preliminary results suggest ZNF652 could be a marker that will predict poor prognosis. This proposal will further investigate this finding.
The Landscape Of Cancer Genes And Associations With Prognosis In Breast Cancer Diagnosed In Premenopausal Women

Funding Amount
$700,512.00
Summary
Using state of the art technology, the purpose of this project is understand the implications of known cancer mutations in breast cancer diagnosed in premenopausal ER-positive breast cancer. Mutations are abnormalities in the DNA of genes that can provide a signal for uncontrolled growth, a hallmark of cancer. The unique aspect of this project is use of tissue samples from patients who were diagnosed with breast cancer at a young age. This information will help us develop new treatments.
Targeting The Oncoprotein MDMX As A Novel Treatment For Triple Negative Breast Cancer

Funding Amount

Summary
Breast cancer (BrCa) is a leading cause of cancer death in women worldwide. BrCas unable to respond to current therapies have the worst outcomes. We propose a novel strategy to treat these cancers, based on our new findings. Our two protein targets are: (1) MDMX, that we found drives BrCa with its partner, (2) mutant p53, which causes cancer spread. We plan to directly target these drivers of aggressive BrCas, using new drugs that individually show great promise in trials in a number of cance
Contribution Of MDSC-derived Cysteine Cathepsins In Breast Cancer Metastasis To Bone

Funding Amount
$320,891.00
Summary
Cathepsins are enzymes called proteases that function to cleave specific proteins, a process that is important for many normal cellular functions. Aberrant cathepsin activity can result in a number of pathologies, including cancer and inflammation. We are developing tools called activity-based probes to study the function of cathepsins in disease. Specifically, we will investigate their activity within cells of the immune system with the goal of developing novel therapeutic approaches.
EAR2: A Novel Driver Of Breast Cancer Proliferation
Funder

Funding Amount
$725,476.00
Summary
Drugs that block oestrogen are effective breast cancer treatments, but many patients are resistant to their effects. This research addresses a protein known as EAR2, that is elevated in breast cancer tissue compared to normal breast. We hypothesise that EAR2 drives breast cancer cell proliferation, and will test this using cell lines and mouse models. We will validate EAR2 as a new therapeutic target, benefitting patients underserved by current hormone therapies.
We have identified genetic abnormalities in 5% of breast cancers that fall in a novel DNA element called BIME1. This proposal aims to determine whether these genetic abnormalities contribute to breast tumourigenesis and which genes and pathways are affected by these mutations. The outcomes of this proposal may lead to the development of novel therapies for breast cancer or could influence the choice of existing therapies for patients that harbour these genetic abnormalities.
