Title	The proteome of irradiated glioma stem cells and of their extracellular vesicles
Description	Glioblastoma is a malignant brain tumor that is highly resistant to radiation and chemotherapy, where patients survive on average only 15 months after diagnosis. Furthering the understanding of mechanisms leading to radiation resistance of glioma is paramount to identify novel therapeutic targets. Previous studies have shown that glioma stem cells (GSCs) play an important role in promoting radiation resistance and disease recurrence. Herein we analyze the proteomic alterations occurring in patient-derived GSCs upon radiation treatment in order to identify molecular drivers of resistance. We show that proteome changes upon radiation accurately predict the resistance status of the cells, and that resistance to radiation does not correlate with glioma transcriptional subtypes. We further show that the radio-resistant cell line GSC-267 sheds microvesicles (MVs) enriched in the metabolic enzyme nicotinamide phosphoribosyltransferase (NAMPT).
