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.
Interleukin-3 Receptor Signaling Is A Driver Of Myeloid Leukaemia And A Significant Therapeutic Target

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.
Fzd receptors are often upregulated in gastric cancer, and recent studies have shown that targeting these receptors has be effective at reducing cancer cell growth in other cancers including prostate and breast. This project will use cutting edge technology to firstly determine the specific requirement for Fzd receptors during gastric cancer and then determine the therapeutic benefit of using an antibody to target these receptors in mouse models and human gastric cancer cells.
Breast cancer is the most frequent malignancy among women, with an estimated 1 million new cases per year worldwide. A family of enzymes known as protein tyrosine kinases (PTKs) are fundamental in the initiation and progression of tumour growth and they are frequently hyperactivated in breast cancer. This proposal will examine whether inactivation of the enzyme known as TCPTP contributes to PTK hyperactivation and tumorigenicity in breast cancer.
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.
Alpha-actinin-4 As An Oncogenic Driver And Therapeutic Target In Melanoma

Summary
Despite the recent advances in targeted therapy and immunotherapy, curative treatment of metastatic melanoma remains an unmet health problem. In this project, we will potentially demonstrate that a protein called ACTN4 is abnormally expressed at high levels in melanoma cells and plays an important role for melanoma cell survival and resistance to treatment, and thus identify inhibition of ACTN4, either alone or in combination with other drugs, as a novel approach in the treatment of melanoma.
An exciting area of drug discovery involves targeting Hippo pathway proteins, particularly one called YAP, which were discovered by members of our research team and which are highly active in some cancer cells, making them grow and spread. We will test whether YAP is a potential drug target to prevent or treat melanoma, a deadly type of cancer that usually arises in the skin but also internal organs and the eye. If so, we would fast-track these drugs for testing in patients via clinical trials.
Transcriptional Effectors Of Oncogenic ERK Signaling In Colorectal Cancer

Funding Amount

Summary
This project aims to unravel how one of the most frequently deregulated molecular pathways in colorectal cancer controls the expression of genes required for these tumours to grow and spread. We expect this work to uncover novel therapeutic targets to effectively inactivate this pathway and biomarkers to select patients most likely to benefit from existing therapies.
