P53 Competitively Binds P300 to Suppress HIF‐1α/TFRC‐Mediated Ferroptosis and Promote Doxorubicin Resistance in Breast Cancer
P53 promotes DOX resistance by suppressing HIF‐1α/P300‐mediated TFRC transcription and TFRC‐dependent ferroptosis, highlighting the P53/P300/HIF‐1α/TFRC axis as a potential therapeutic target in DOX‐resistant breast cancer.
