Targeted therapy resistance has become a major challenge for hepatocellular carcinoma (HCC) treatment. Triggering ferroptosis emerges as a promising strategy to overcome therapeutic resistance. Here, we have identified ubiquitin-specific protease 18 (USP18), a member of the deubiquitinating enzyme f...
