SF3B1 and glioblastoma: Likewise, SF3B1 was expressed in all transcriptional programs of GBM cells that recapitulate distinct neural cell states (NPC-like, MES-like, AC-like, OPC-like; Fig. 1j) [50], wherein a higher expression was found in neural progenitor-like program (with proliferative potential) than the other programs (Fig. 1k).
