Zhang G et. al. (December 2023). Targeting AKT induced Ferroptosis through FTO/YTHDF2-dependent GPX4 m6A methylation up-regulating and degradating in colorectal cancer Cell Death Discov. 9(1):457.
This study reveals that downregulation of demethylase FTO during AKT targeting increases m6A methylation of GPX4, facilitating its degradation by YTHDF2. The identified methylated site (193) undergoes FTO-mediated demethylation and YTHDF2 recognition. AKT inhibition elevates ROS levels, negatively regulating GPX4 expression. Protective autophagy is triggered by MK2206, and its inhibition enhances ferroptosis, intensifying MK2206's anti-tumor efficacy. This uncovers the FTO/YTHDF2/GPX4 axis as a potential therapeutic target for CRC.
