hese patients, so a PRMT5 inhibitor might be particularly important for these patients," says Kaur, who is specializes in glioblastoma research and is chief of Ohio State's Dardinger Laboratory of Neurosciences.

PRMT5 (protein arginine methyltransferase 5) is an enzyme that alters the structure of chromatin to suppress the transcription of genes and the production of proteins. To conduct their study, Kaur, Baiocchi and their colleagues used tumor tissue from patients, cell lines and an animal model. Key findings included:

  • PRMT5 is selectively over-expressed in glioblastoma and the degree of PRMT5 expression correlates with cell growth and patient survival.
  • In GBM patients, PRMT5 expression levels in tumor were significantly associated with lower overall survival;
  • Patients with high PRMT5 tumor expression had shorter overall survival (108 days) compared to patients with medium expression (277 days) and low expression (726 days).
