The accumulation of mutations during the development of cancer subverts normal cell-to-cell communication and cellular decisions. Deciphering the mechanisms that underlie cell decisions such as fate determination, cell cycle regulation and cellular migration is critical not only to identifying the molecular determinants of disease but also to the development of future cancer therapies. In particular, our understanding of the role and mechanisms of heterotypic cellular interactions during oncogenesis and therapy is severely lacking, hampered by methodological challenges associated with monitoring cell-to-cell communication between individual cells over time.
Dr Alessandro Esposito and his team have established techniques to enable live imaging of biochemical activities with subcellular resolution, light-inducible control of enzymatic activities, tracking and modelling of cellular populations. We are applying these unique tools to the study of how oncogenic KRAS mutations alter cell signalling and metabolism, and cellular phenotypes during early oncogenesis. Dr Jacqueline Shields and her team investigate how the “normal cells” of the tumour microenvironment - the stroma - regulate immune activity from early stages of disease to promote carcinogenesis. To do this, we examine both the primary tumour and draining lymph nodes developing complex culture systems and organ-on-a-chip models to monitor heterotypic cell interactions with low invasiveness.
This project will exploit these novel technologies to understand how oncogenic KRAS mutations alter cell-to-cell interactions between wild-type and mutant cells or between mutant cells and stroma contributing to the deregulation of tissue homeostasis during early oncogenesis. The project will offer a unique opportunity to train across disciplines through a strong partnership between groups specializing in oncology, engineering and biophysics.
