Pseudouridine is the most frequent epitranscriptomic modification. However, its cellular functions remain largely unknown. Here, we show that pseudouridine synthase 7 (PUS7) is highly expressed in glioblastoma versus normal brain tissues, and high PUS7 expression levels are associated with worse survival in patients with glioblastoma. PUS7 expression and catalytic activity are required for glioblastoma stem cell (GSC) tumorigenesis. Mechanistically, we identify PUS7 targets in GSCs through small RNA pseudouridine sequencing and show that pseudouridylation of PUS7-regulated transfer RNA is critical for codon-specific translational control of key regulators of GSCs. Moreover, we identify chemical inhibitors for PUS7 and show that these compounds prevent PUS7-mediated pseudouridine modification, suppress tumorigenesis and extend the life span of tumor-bearing mice. Overall, we identify an epitranscriptomic regulatory mechanism in glioblastoma and provide preclinical evidence of a potential therapeutic strategy for glioblastoma.
