Researchers from the Hemann, Lees, and Sharp laboratories joined forces in the fight against glioblastoma. Using a novel screen, the collaborative team identified PRMT5 as a protein involved in the tumors’ growth, and found that PRMT5 uses a special type of gene splicing to promote this growth.The researchers showed that inhibiting PRMT5 halted cancer cell growth in mice, and also identified a biomarker that could be used to predict which patients would benefit from treatment with existing PRMT5 inhibitors, at least one of which is currently in clinical trials for cancer. Their findings, described in Cancer Cell, help explain PRMT5’s poorly understood role in cancer and offer opportunities to improve current therapies and develop new ones. The team hopes to develop nanoparticles to help PRMT5 inhibitors cross the blood-brain barrier, and is also looking at PRMT5’s role in other tumor types.
