My main research interest is in the role of growth factor receptor signalling and trafficking in tumour metastasis.

We study compartmental signalling of a molecule called c-Met in relation to its endosomal trafficking (how it is moved around the cell in vesicles) and the effects on tumour cell migration and invasion in vitro and in vivo. We use confocal microscopy, live imaging, biochemistry, trafficking / internalisation assays, functional assays, and in vivo tumorigenesis assays. We investigate the clinical relevance of our findings on patient samples through collaboration with clinicians.
Most solid cancers start as a small lump of abnormal cells (a tumour) that divide in an uncontrolled fashion. As primary tumours grow, some cancer cells can detach, move away and, eventually, colonise another part of the body. This aggressive process is called metastasis and is the major cause of cancer treatment failure and death. Our research focuses on understanding the mechanisms of c-Met in promoting this process of metastasis.
Receptorsare normally present at the surface of transformed cells in the tumour mass, where they transmit information (signals) from the outside to the inside of the cell in order to change its behaviour (divide/don’t divide; move/don’t move). However, receptors can enter cells (endocytosis) and recently have been found to transmit signals from within the cell. This is a new scientific concept that changes our understanding of how receptors function.
c-Met is overexpressed or mutated in a large number of tumours and has emerged as a major target for cancer therapy. c-Met is a tyrosine kinase receptor (RTK). Together with the protein that binds to it: its ligand, Hepatocyte Growth Factor (HGF), they are key players in tumour metastasis. They affect cell adhesion, migration, invasion, metalloproteinase activation and angiogenesis. Drugs against c-Met are being designed and some are being tested in patients in clinical trials.
Key finding: We reported that in invasive basal-like breast cancer cells, not only is c-Met endocytosis important but the endosome from which c-Met signals plays a major role in determining cell behaviour, including migration (Menard et al, Nat Com 2014).

I completed my PhD with Dr. Thérèse Lehy at the French National Institute of Health and Medicine (INSERM) and Paris VII University, France, in 1999.
Between 2000 and 2005, I performed postdoctoral studies with Professor Peter J Parker at the Cancer Research UK London Research Institute.
I joined the Centre for Tumour Biology at the Barts Cancer Institute in May 2005, as a Lecturer. Thanks to a “Medical Research Council New Investigator Award” and funding from the “Barts and the London Charitable Foundation”, I set up my research group “Spatial Signalling”, which is investigating the role of growth factor receptor signalling and trafficking in tumour metastasis.
