Proteomic profiling of glioblastoma stem cells and their small extracellular vesicles


ABSTRACT: The heterogeneous nature of glioblastoma stem-like cells (GSCs) creates hurdles in developing effective therapies against glioblastoma, making it extremely difficult to eradicate. In this part of the project, we investigated the potential role of GSCs-derived small extracellular vesicles (sEVs) in glioblastoma heterogeneity, plasticity, and aggressiveness with the particular focus on their complexity in term of proteins. Proteome profiling of sEVs and their respective cell lines showed that GSCs-derived sEVs retain their subtype characteristics and are enriched in proteins playing a role in amino acids, carboxylic acids, organic acids transmembrane transport, and growth factor binding. In summary, we revealed the protein content of GSCs-derived sEVs and unveiled their potential contribution to tumor heterogeneity and critical cellular processes commonly deregulated in glioblastoma.

Glioblastoma is a deadly brain tumor for which there is no cure. The presence of glioblastoma stem-like cells (GSCs) contributes to the heterogeneous nature of the disease and makes developing effective therapies challenging. Glioblastoma cells have been shown to influence their environment by releasing biological nanostructures known as extracellular vesicles (EVs). Here, we investigated the role of GSC-derived nanosized EVs (<200 nm) in glioblastoma heterogeneity, plasticity, and aggressivenes  ...[more]
