MYB proto-oncogene, transcription factor (MYB)-mediated expression of cysteine dioxygenase type 1 (CDO1), an enzyme that converts cysteine to taurine by catalyzing the oxidation of cysteine to sulfinic acid, can promote erastin-induced death in gastric cancer cells,89 indicating that non-GSH-dependent cysteine metabolism is also involved in controlling ferroptosis. Here, CDO1 is linked to gastric cancer.
