Summary
Leukaemia is a devastating form of blood cancer affecting both young and old. We need to understand the diseased stem cell to eradicate this disease. Current therapy is poorly tolerated and the majority of patients ultimately die at relapse. We intend to investigate how we can make the cells more susceptible to therapy by understanding their biology.
Wnt-5a Signalling - A Novel Therapy For Triple Negative And Tamoxifen Resistant Breast Cancer Patients

Summary
Breast cancer is the most common cancer in women. Commonly used drugs target the estrogen receptor (ER). However, one third of breast cancer patients lack ER, and do not respond to treatment. Cancers that lack ER also lack a gene called Wnt5a, which is linked to better prognosis. We have shown that fixing Wnt5a can restore ER allowing cells to respond to Tamoxifen. We would now test this in animals, in the hope of developing a new drug for breast cancer patients currently with limited options.

Summary
Acute Myeloid Leukaemia (AML) is an aggressive blood cancer. There are many types of AML, but overall, less than half of those with AML are cured. This project evaluates how certain molecules on the surfaces of leukaemic cells keep those cells alive and growing. We are also testing new ways to block these molecules and so provide new therapies for this cancer.
This study focuses on key endocrine pathways involved in the remodelling of the breast stromal cells into a reactive stromal environment which is more permissive for tumour growth. We have identified key pathways involved in the regulation of estrogen biosynthesis and fibrosis in tumour associated stroma. These studies will lead to the development of novel breast cancer therapies.

Summary
Most leukaemias are incurable so it is important to find new treatments. For this to occur it is essential that the mutated genes that cause leukaemia are identified. We have generated a mouse with a mutation in a gene called c-Cbl that promotes the activation a protein called FLT3 that is involved in the development of many types of leukaemias. By treating mutant mice a drug that specifically suppresses the function of FLT3 we intend to identify the most effective treatments for human leukaemia ....Most leukaemias are incurable so it is important to find new treatments.

Dual Targeting Of The Androgen Receptor For Effective And Durable Control Of Lethal Prostate Cancer

Summary
Preventing binding of androgens to the androgen receptor is the mainstay treatment for advanced prostate cancer, but resistance inevitably develops and the disease becomes lethal. We will develop a new drug that targets a part of the androgen receptor unrelated to its androgen binding function to overcome resistance to current therapy. As this drug will be effective in all stages of prostate cancer, it has high potential to improve survival outcomes for men with prostate cancer.

Summary
Reactive oxygen species (ROS) produced in cancers activate cell surface receptor signalling pathways that drive cancer progression. I will study links between ROS and receptor signalling in cancer cells, and inhibit signalling with ROS scavengers delivered in nanoparticles, targeted to receptor complexes with specific antibodies. These will include antibodies we raised against ADAM10, a protease associated with multiple receptor signalling pathways, to simultaneously inhibit these pathways.
