Ferroptosis is an iron-dependent form of regulated cell death linking iron, lipid, and glutathione levels to degenerative processes and tumor suppression. By performing a genome-wide activation screen, we identified a cohort of genes antagonizing ferroptotic cell death, including GTP cyclohydrolase-1 (GCH1) and its metabolic derivatives tetrahydrobiopterin/dihydrobiopterin (BH<sub>4</sub>/BH<sub>2</sub>). Synthesis of BH<sub>4</sub>/BH<sub>2</sub> by GCH1-expressing cells caused lipid remodeling ...[more]
