To develop a new molecular targeted treatment for brain arteriovenous malformation(AVMs), identification of membrane proteins that are expressed on AVM endothelium is crucial. In this study we employed in vitro and in vivo biotinylation methodology to targetcell membrane proteins in murine cerebral endothelial cell cultures (bEnd.3) and the rat model of AVM. Two forms of mass spectrometry were applied (iTRAQ-MS and MSEanalysis) to identify and quantify membrane protein expression at various time point following irradiation to simulate a radio surgical treatment approach. The proteomics data revealed several differentially expressed membrane proteins between irradiated and non-irradiated cells at specific time points, e.g. PECAM-1, cadherin5, PDI, EPCR, integrin├ó┬?┬?s and ion channel proteins. Immunocytochemistry was used to confirm the expression of selective membrane proteins. This novel work provides potential target protein molecules for evaluation in animal models of brain AVM.
