One group previously reported that the first-generation dopamine receptor antagonist trifluoperazine in combination with radiation prolonged survival in mouse models of glioblastoma, but ultimately, the mice become resistant to the therapy. To help overcome this resistance, the team used quetiapine, a second-generation dopamine receptor antagonist, which not only enhanced the efficacy of radiotherapy in glioblastoma, but also generated a metabolic vulnerability in the lipid homeostasis. The discovery that the combination induced the cholesterol biosynthesis pathway allowed the team to target this process with statins. Atorvastatin was selected because of its known ability to cross the blood-brain-barrier
