フェロプトーシス制御におけるm6Aメチル化：メカニズム、標的、および治療的介入

The dynamic crosstalk between N6-methyladenosine (m6A) RNA methylation and ferroptosis is pivotal for understanding disease pathogenesis. As the most abundant form of eukaryotic mRNA modification, m6A methylation guides RNA metabolism through writers, erasers, and readers. Ferroptosis, an iron-dependent and lipid peroxidation-driven form of cell death, occurs under conditions including dysregulated iron metabolism, compromised antioxidant defences, and lipid peroxidation.

This review highlights recent progress in basic research and proposes potential therapeutic targets for diseases of different systems while also addressing current drugs and challenges. KEY SCIENTIFIC CONCEPTS OF REVIEW: m6A RNA modification is governed by three types of effector proteins-writers, erasers, and readers-while the molecular mechanisms governing ferroptosis involve three interconnected biological axes: iron metabolism homeostasis, redox balance, and lipid peroxidation dynamics. Studies have indicated that m6A methylation regulates the expression of ferroptosis-related proteins, thus influencing tumorigenesis, progression and pathogenesis. This review also summarizes currently available agents targeting m6A-related targets as well as those associated with both m6A and ferroptosis, aiming to highlight their potential for clinical applications.
