A recent study by Brashears et al. showed that synovial sarcoma lacks ME1 expression which drives decrease in intracellular NADPH and GSH levels.[33, 34] Interestingly, ME1 deficiency render synovial sarcoma cells sensitive to erastin‐induced ferroptosis, but resistant to GSH depletion‐induced cell death. The gene discussed is ME1; the disease is synovial sarcoma.
