However, the detailedmolecular mechanisms underlying the relationship between these two cell types remainunclear. Here, we demonstrate that ARS2 (arsenite-resistance protein 2), a zinc finger proteinthat is essential for early mammalian development, plays critical roles in GSC maintenanceand M2-like TAM polarization. ARS2 directly activates its novel transcriptional target MGLL,encoding monoacylglycerol lipase (MAGL), to regulate the self-renewal and tumorigenicityof GSCs through production of prostaglandin E2 (PGE2), which stimulates β-cateninactivation and M2-like TAM polarization. Specific knockdown of ARS2 or MAGLsignificantly suppressed self-renewal and tumor growth, and increased survival in a mouseintracranial xenograft model of GSCs. We identified M2-like signature downregulated bywhich MAGL-specific inhibitor, JZL184, increased survival rate significantly in the mousexenograft model. The M2-like signature was enriched in mesenchymal subtype and predictedpoor survival in GBM patients. Taken together, our results suggest that blocking the interplaybetween GSCs and TAMs by targeting ARS2/MAGL signaling offers a potentially noveltherapeutic option for GBM patients."],"repository":["ENA"],"additional_accession":[]},"is_claimable":false,"name":"","description":"ARS2/MAGL signaling in glioblastoma stem cells promotes self-renewal and M2-like polarization of tumor-associated macrophage","dates":{"last_updated":"2019-06-13","first_public":"2019-08-12"},"accession":"PRJEB33027","cross_references":{}}
