3'mRNA-Seq of drug-tolerant medulloblastoma cell lines.

Stable cisplatin- and vincristine-tolerant Group 3 and SHH cell lines were generated by continuous drug exposure with dose escalation to identify mechanisms driving resistance to standard-of-care medulloblastoma therapy. Next-generation sequencing revealed a vastly different transcriptomic landscape following chronic drug exposure, including a drug-tolerant gene expression signature, common to all sequenced drug-tolerant cell lines.
