The GCH1 (GTP cyclohydrolase 1)/tetrahydrobiopterin (BH4) pathway counteracts ferroptosis through lipid remodeling independent of GPX4. SPY1 activates GCH1 to suppress ferroptosis in ALS by regulating TFR1-mediated iron import. Pharmacological GCH1 activation or BH4 supplementation could provide GPX4-independent ferroptosis defense.
