Systematic Evaluation Defines the Limits of Ferroptosis in Cancer Therapy
This study systematically demonstrates that while ferroptosis induction via the GPX4 axis fails to impact established tumors in vivo, inhibiting cytosolic thioredoxin reductase or GCLC triggers potent tumor regression through a distinct, non-ferroptotic cell death mechanism, revealing that standard cell culture models significantly overestimate the therapeutic potential of ferroptosis.
