Summary
Endometrial cancer is a common gynecological cancer in women and new therapies are required to improve survival rates. We have identified mutations in a key cell membrane protein (FGFR2) and shown that endometrial cancer cells with these mutations have altered growth factor dependence. Inhibiting these mutant proteins can result in cell death. By characterizing these mutations and their cellular effects we will be able to develop specific blocking agents for use as potential novel treatments

Summary
A feature of late-stage cancer is metastasis - the dissemination of cancer cells to other tissues. Despite advances in treatment of primary cancers, metastatic disease remains the major cause of death in cancer patients. In metastatic cancers, the cells undergo a change that enables them to initially invade the surrounding tissues. We have discovered a novel regulator of the invasive process in tissue culture and this study aims to substantiate its role in breast cancer.
A Novel Protease And Growth Factor Regulated Signalling System In Ovarian Cancer

Summary
Ovarian cancer is the leading cause of gynaecologic cancer death. Our project focuses on the role in ovarian cancer of a cellular receptor called CDCP1. We have previously shown that CDCP1 promotes growth and spread of ovarian tumours. Recently we have generated new data indicating that CDCP1’s activity is markedly increased by other proteins called proteases and growth factors. In this project we will define how these new pathways function, and if their blockade impedes ovarian cancer.
I am a cancer biologist determining the mechanisms controlling growth and proliferation of cancer cells and use transgenic models of malignancy and genetic approaches to identify new therapies for targeting growth control in the treatment of cancer.
Targeting Homeobox Genes In Acute Myeloid Leukaemia

Summary
Acute myeloid leukaemia (AML) is a common blood cancer with dire clinical prognosis due to a lack of targeted molecular therapies. In this proposal we will identify new ways of targeting transcription factor proteins that are overexpressed in AML and promote leukaemia by repressing normal cellular growth controls. This may lead to novel methods to target leukaemic stem cells to specifically eliminate myeloid leukemia
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.
Defining The Role Of Microphthalmia-associated Transcription Factor (MITF) In Melanoma Heterogeneity By Real-time Cell Cycle Imaging

Summary
Metastatic melanoma is highly therapy-resistant. Modern targeted therapy is promising but suffers from rapid onset of drug resistance. Tumours consist of zones of fast growing cells next to zones of dormant cells. This tumour heterogeneity is one of the reasons for cancer drug resistance, as cells in different growth states respond differently to drugs. By understanding the causes of tumour heterogeneity we will set the basis for innovative clinical approaches against this devastating disease.
Therapeutic Targeting Of Ribosome Biogenesis In Cancer And Ribosomopathies

Summary
My fellowship application will build on my international leadership in understanding growth control in human disease. My vision is to uncover the molecular mechanisms governing the loss of normal control of the synthesis of the molecular machines, termed ribosomes, that are responsible for synthesising all cell proteins. I will translate these findings into new paradigms to treat patients suffering from diseases such as cancer and ribosomopathies, that are associated with ribosome dysfunction.
