Summary
It is thought that understanding cancer metabolism will reveal vulnerabilities that can be exploited in the clinic. Indeed, compared to most normal cells, cancer cells utilise different fuels to sustain proliferation and to adapt to their environment. Herein we have discovered a molecular switch that regulates the key metabolic enzyme IDH1 and show this controls tumour growth. Given this switch may be active in 50% of cancers we anticipate our work will have significance to many cancer types.
Role Of Proline-rich Tyrosine Kinase 2 (Pyk2) In Ovarian Cancer

Summary
Ovarian cancer is one of the most lethal gynaecological cancers in the developed world. Elevated levels of gonadotropin hormones and cell protein Pyk2 have been implicated in ovarian cancer. Our aim is to determine the role of Pyk2 in growth and metastasis of ovarian cancer when stimulated with gonadotropins. In addition, we aim to identify protein changes which occur in ovarian cancer when stimulated by gonadotropins in order to identify new biomarkers for the disease.
Interplay Between Metabolic Reprogramming And Oncogenic Signalling In The Cellular Response To Chemotherapy

Summary
Chemotherapy resistance is a major barrier to the treatment of triple-negative breast cancer (TNBC). We seek to uncover an intimate link between cell metabolism and oncogenic signalling pathways in regulating the cellular response to chemotherapy. Our studies will identify a critical mechanism limiting the therapeutic efficacy of chemotherapy and investigate combination therapy strategies that could improve the treatment of TNBC.
Stopping Breast Cancer Progression By Targeting Tumour Stroma

Summary
Our latest research demonstrated that CRELD2 protein that is secreted by breast cancer cells alters normal cells surrounding tumour. CRELD2 represents an ideal therapeutic target as it is not important for normal cells and it is a secreted protein and thus can be targeted by numerous means. Successful completion of this research proposal will provide foundation to find new targets for combining therapies affecting both tumour and it's altered environment in breast and potentially other cancers.
The Molecular Mechanisms Of Abscission To Complete Cytokinesis

Summary
Cytokinesis is the final stage of cell division that produces two daughter cells. Incorrect localisation and modification of proteins that regulate this process cause cell division errors potentially leading to cancer. This project will characterise how key cytokinesis proteins co-operatively function to complete cytokinesis. This research will increase our understanding of the cell division errors that contribute to cancer development, ultimately identifying new targets for cancer therapy.
The migration of cancer cells (metastasis) is responsible for most cancer deaths. Central to this is dynamic organisation of the actin cytoskeleton _ an internal structure that provides cell shape and enables movement. We have identified a family of small molecules (called miR-200) that regulates this actin cytoskeleton through specifically downregulating various genes. We are investigating the nature of these genes and their role in cell motility _ an underlying pre-requisite of metastasis.
Investigating Signalling Pathways That Mediate Suppression Of Anoikis By Chemokine Receptors In Metastatic Breast Cancer Cells

Summary
This research aims at understanding the "nuts and bolts" of the main killer in cancer patients - tumour metastasis. We will look for molecules that are specific to metastatic tumour cells that transmit signals from the cell surface to the cell "suicide" machinery and prevent metastatic cancer cell death.
I am a molecular-cell biologist determining the molecular regulation, cellular localisation and function of tumour suppressor proteins in cancer. We aim to elucidate pathways that can ultimately be targeted for intervention in breast and colon cancer.
UNDERSTANDING FOCAL ADHESION DYNAMICS IN CELL MIGRATION

Summary
Metastatic (secondary) cancers are a frequent cause of patient mortality. Central to the development of metastasis is cell motility-movement. A key component of cell movement is the way that cells bind and release the extra-cellular matrix as they move. By understanding how the dynamics of cell interaction with the matrix are regulated, we will identify molecules that are critical to the development of metastatic cancer and thus novel targets for inhibition of metastasis.
