Abstract
Protein arginine methyltransferase 5 inhibitors represent a promising therapeutic approach for multiple cancers, but their clinical development is hindered by toxicity to normal cells. Synthetic lethality approaches using MTAP-cooperative protein arginine methyltransferase 5 inhibitors offer a compelling strategy that selectively targets cancer cells in nerve sheath sarcomas and other MTAP-deleted tumors.
