Using an adeno-associated virus–mediated, direct in vivo CRISPR screen, the authors mapped a quantitative landscape of glioblastoma suppressors. Their study revealed gene combinations that functionally drive gliomagenesis from normal glia in native mouse brains. The authors further demonstrate that mutational background can differentially influence gene expression and chemotherapeutic resistance.
