There are about 190,000 new brain tumour diagnoses annually and the prognosis following a brain tumour diagnosis is less than 18 months survival (Curr Oncol Rep, 2010 12, 26). The current proposal seeks to test the hypothesis that targeting gene silencing to the brain tumour vasculature is a viable glioblastoma treatment strategy. Our aim is to exploit recent findings on nanoparticle adherence to the luminal side of brain endothelial cells (J Raman Microscopy, 2012, 43, 668) to explore the possibility of achieving selective gene silencing of vascular endotheiial growth factor (VEGF) and thus a brain tumour selective anti-angiogenic effect.
