The University of Sheffield Faculty of Medicine, Dentistry & Health Department of Clinical Dentistry Title Primary Supervisor: Dr Stuart Hunt – [email protected] Project: Does microsomal transfer of microRNA play a role in stromal-epithelial interactions? In recent years, the importance of the tissue surrounding cancers, termed the tumour stroma, has become increasingly recognised. Indeed, a recent report provided evidence that the gene expression profile of the stroma is a more accurate predictor of disease outcome in head and neck cancer than that of the cancer cells themselves. The stroma is composed of a number of cell types, including fibroblasts, endothelial cells, immune cells and neurones. Communication between these cells by secreted factors is known to be a key factor in disease progression, and is likely to represent a good therapeutic target for novel therapies. Recently, it has become apparent that, as well as secreted proteins, small membranous vesicles termed microvesicles play a key role in cell:cell communication, and evidence is mounting that these vesicles may be important in the tumour stroma. We have preliminary data showing that microvesicles can be isolated from head and neck cancer cells and primary oral fibroblasts, and that they contain intact RNA. This project will utilise a variety of cutting edge cell and molecular biology techniquesse to characterise the microvesicles released by both cancer cells and stromal fibroblasts, to examine their importance in communication and influencing cancer and stromal cell behaviour. Furthermore, the project will analyse whether microRNA, regulatory non-coding RNA known to be present in microvesicles, mediate any effects observed.
