Dataset Summary
TitleSurfaceome proteomic of glioblastoma revealed potential targets for immunotherapy
DescriptionGlioblastoma (GBM) is the most common and devastating malignant brain tumor in adults. The mortality rate is very high despite different treatments. New therapeutic targets are therefore highly needed to improve patient care. Cell-surface proteins represent attractive targets due to their accessibility, their involvement in essential signaling pathways, and their dysregulated expression in cancer. Moreover, they are potential targets for CA-based immunotherapy or mRNA vaccine strategies. However, cell-surface proteins are often underrepresented in standard proteomic data sets, due to their poor solubility and lower expression levels compared to intracellular proteins. In this context, we investigated GBM-associated surfaceome by comparison to healthy astrocytes surfaceome to identify new specific targets to GBM. For this purpose, biotinylation of cell surface proteins has been carried out in GBM and healthy astrocytes cell lines. Biotinylated proteins were purified on streptavidin beads and analyzed by shotgun proteomics. After filtering our data with Cell Surface Proteins Atlas (CSPA) and Gene Ontology, 78 overexpressed or exclusive in GBM have been identified. Validation has been performed using Human Protein Atlas. In this context, we identified 21 specific potential targets for GBM including 5 mutated proteins (RELL1, CYBA, EGFR, and MHC I proteins). Taken together, we identified potential targets for immune therapy strategies in GBM.
