Abstract:Glioblastoma (GBM) is the most common and aggressive primary brain malignancy. Despite multimodal therapy, resistant GBM stem-like cells (GSCs) inevitably mediate disease recurrence. To identify novel vulnerabilities of GSCs, we performed an arrayed CRISPR/Cas9 screen against select adhesion G protein-coupled receptors (aGPCRs), many of which we found to be de novo expressed in GBM. Knockout of CD97 (ADGRE5), previously implicated in GBM cell migration, produced the most striking proliferative disadvantage in … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
