Identifying And Characterizing Genes That Regulate Breast Tumorigenesis And Metastasis

Summary
I am a breast cancer biologist. My research focuses on identifying the changes in normal cells that allow cancer to form, and identifying the changes in cancer cells that allows them to spread. To accomplish this, I have developed new methods using mouse models of breast cancer. My goal is to use these methods to further our understanding of the causes of breast cancer development and progression.
Using Bioengineered 3D Models To Replicate The Tumour Microenvironment In Prostate Cancer

Summary
The research will address the poor prognosis of patients with advanced prostate cancer bone metastasis by establishing a novel 3D bioengineered bone model containing high amounts of fat cells, where cancer cells can relocate. This approach will help identifying the impact of fat cells on cancer cell function, and help determine whether fat cells are legitimate therapeutic targets, ultimately assisting clinicians to select better therapies for prostate cancer bone metastasis.
Cancer remains a major cause of morbidity and mortality in the developed & developing world. Underpinning the causes of cancer are genetic and cellular changes in key structural proteins that control cell growth and movement. My research aims to discover key links in the regulation of these proteins that lead to tumour formation, metastasis and drug resistance. My goal is to use this knowledge to develop effective and less toxic treatment strategies to target difficult-to-treat cancers.
Characterisation Of A Novel PI3-kinase Signal Terminating Enzyme In Breast Cancer.

Summary
Breast cancer is the most common malignancy among females, affecting 1 in 9 women before the age of 85. Normally cells divide only when they receive a stimulus from a hormone or growth factor. The PI3K pathway which responds to these stimuli has been implicated in cancer where cells divide uncontrollably and invade surrounding tissue. We have identified a potential cancer suppressing gene, PIPP, which turns off PI3K growth signals. We aim to characterize the role of PIPP in breast cancer.

Summary
Breast cancer is the most common malignancy among females, affecting 1 in 9 women. Cells normally divide only when they receive a stimulus. The PI3K pathway, which responds to these stimuli, has been implicated in cancer and when mutated induces cells to multiply uncontrollably and invade surrounding tissue. This grant aims to characterise the role of a cancer suppressing gene and a related family member play in the development of human breast cancer.
Tumour Induced Innate Immune Responses That Control Breast Cancer Metastases

Summary
The mechanisms of breast cancer spread to bone are largely unknown. We have found that cross-talk between tumour cells and the immune system exists to induce anti-tumour immune responses. By decreasing the release of proteins known to activate immune responses (type I interferons), tumour cells can hide from such responses and spread to tissues such as bone. We aim to identify the immune responses activated by type I IFN and if restoration of these pathways can block breast cancer spread to bone ....The mechanisms of breast cancer spread to bone are largely unknown.

The Contribution Of Host Caveolin-1 To Breast Cancer Metastasis

Summary
Mortality in breast cancer rises to 80% in cases where secondary tumors form in other organs. To improve outcome, a better understanding of the processes involved in cancer spread is needed. Normal cells contribute to the growth and spread of a tumour and are a target for therapy. When a protein called caveolin-1 is lost from normal cells in a tumour, the prognosis for the patient is much worse. The aim of this project is to understand how this protein can regulate the spread of breast cancer.
It is seldom the initial cancer that kills the patient; most deaths are due to its metastatic spread throughout the body. Survival after the onset of a brain metastasis is dismal. Current understanding of cancer spread to the brain is poor and yet an ability to inhibit this process would save thousands of lives each year. Using rare tissue resources and cutting-edge technologies, this project will elucidate molecular features of brain metastases that can be exploited to generate new treatments.
TARGETING OF G-CSF IN COMBINATION WITH STANDARD THERAPY FOR ADVANCED BREAST CANCER

Summary
Nearly all deaths caused by breast cancer are due to the spread of the cancer to other tissues such as lung and bone, ultimately leading to organ failure and death. The process of spread of cancer cells is not well understood, but it is becoming clear that cells of the immune system are key regulators of the spread of breast cancer. It is the aim of this project to target two types of immune cells, macrophages and neutrophils, seeking therapies that prevent the growth of secondary cancers.
