p53 inhibits OTUD5 transcription to promote GPX4 degradation and induce ferroptosis in gastric cancer

OTUD5 mediates GPX4 deubiquitination to regulate its stability. Deletion of OTUD5 promotes ferroptosis and inhibits tumor growth. Wild type p53 inhibits OTUD5 transcription, thereby promoting GPX4 degradation and inhibiting the development of gastric cancer. OTUD5, GPX4 expression and p53 activity are highly correlated and correlates with clinical progression in STAD.
