Abstract:Background: Pediatric high-grade gliomas (PHGG) are aggressive, undifferentiated CNS tumors with poor outcomes, for which no standard-of-care drug therapy currently exists. Through a screen for epigenetic regulators, we identified PRMT5 as essential for PHGG growth. We hypothesized that, similar to its effect in normal cells, PRMT5 promotes self-renewal of stem-like PHGG tumor initiating cells (TICs) essential for tumor growth. Methods: We conducted in vitro assays, including limiting dilution studies of self-… Show more
