I am currently funded by a PCUK research fellowship grant held by Dr Jason Webber. My research focuses on the role of extracellular vesicles, specifically exosomes, in the induction of fibroblast differentiation in prostate cancer. Conversion of prostate stroma fibroblasts to a more myofibroblastic phenotype is an important step in the carcinogenesis of aggressive prostate cancer. We have identified heparan sulphate proteoglycans (HSPGs) as the exosomal surface proteins responsible for driving this differentiation process. Current work involves elucidating the specific HSPGs responsible for exosome driven fibroblast differentation and development of an assay to detect these proteins in serum samples from prostate cancer patients.
