METTL3-driven m⁶A epigenetics in gastric cancer: unveiling oncogenic networks and clinical translation from tumorigenesis to therapy resistance.

ABSTRACT: Globally, gastric cancer (GC) ranks among the deadliest malignancies due to frequent late-stage detection, metastatic dissemination, and resistance to therapies. Emerging evidence highlights N⁶-methyladenosine (m⁶A) modification, orchestrated by methyltransferase-like 3 (METTL3), as a pivotal epigenetic driver of GC pathogenesis. While METTL3 is implicated in promoting tumorigenesis, metastasis, and chemoresistance, a systematic synthesis of its multi-layered regulatory networks and clinical relevance remains elusive. This review comprehensively deciphers METTL3's dual roles as an oncogene and RNA modifier, elucidating its mechanisms in reprogramming GC progression through m⁶A-dependent RNA stability, translation, and non-coding RNA interactions. We reveal novel axes such as HOXA10-TGFβ /S
