Research

Receptor Tyrosine Kinase (RTK) signalling can be a positive driving force for cell proliferation, survival and migration but it is kept under tight control via feedback loops. In cancer, these controls can be bypassed by a variety of mechanisms and we are investigating how this happens.

We focus on breast and pancreatic cancer, using 2-D and 3-D cell-based models to investigate how cellular behaviour changes when cell signalling is altered. We collaborate with clinical colleagues to determine the translational significance of our findings through analysis of patient samples.

Our current research aims:

1. Modelling breast cancer development in 3D culture

3D modelling fulfils a critical role in research, allowing for complex cell behaviour and interactions to be studied in physiomimetic conditions. We have used the Breast Cancer Now Tissue Bank, an invaluable resource of primary cells isolated directly from patients, to interrogate the interactions between myoepithelial and luminal cells in 3D using collagen gels. Using lentiviral transduction of isolated cells, we have developed a model that allows us to study early events in breast cancer development, to help understand how breast cancer progresses, with the ultimate aim of improving early diagnosis and treatment.

We have a number of projects investigating protease dependent activities, proteomic approaches to understanding cross-talk, impact of the innate immune system and RTK crosstalk with cannabinoid receptors.

2. Understanding the molecular basis of pancreatic cancer invasion

Using advanced 3D cell based models we have identified a number of exciting new pathways implicated in stromal-led invasion in pancreatic cancer. We are investigating protease dependent activities, RTK-mediated pathways and purinergic signalling to identify novel biomarkers of disease progression and new targets for therapeutic intervention.

3. Targeting FGFR-mediated cellular crosstalk in cancer

Fibroblast Growth Factor Receptor (FGFR) mutations are key drivers in a number of cancers, where dependency on oncogenic FGFR signalling makes FGFRs attractive targets for targeted therapies. We have worked extensively on endometrial, cervical breast and pancreatic cancer models, showing FGF signalling to play a critical role in cell migration and survival.

We have discovered that, rather than signalling from the cell surface or within endosomes, FGFRs can be proteolytically cleaved following activation and that the cytoplasmic portion of the receptor can traffic to the nucleus and regulate gene transcription. We have identified this behaviour in invasive breast cancer cells both in vitro and in vivo. We have shown that nuclear FGFR signalling is a critical mediator of cancer-stroma cross-talk in pancreatic cancer, and we are exploring the therapeutic potential of FGFR inhibition in blocking pancreatic cancer progression.
