Implication

Review reveals that METTL3 promotes tumor immune escape and metabolic reprogramming across various cancers, highlighting its promise as a target for anti-tumor immunotherapy.

Key Points

  • To comprehensively synthesize current evidence on the structure, biological functions, and molecular regulatory networks of METTL3, specifically emphasizing its roles in tumor immune escape and potential as a therapeutic target.
  • Synthesized molecular and preclinical findings examining METTL3-mediated post-transcriptional gene regulation across malignancies including acute myelogenous leukemia, pancreatic cancer, and colorectal cancer.
  • Analyzed mechanistic pathways linking METTL3 activity to intrinsic cancer cell metabolic reprogramming and functional phenotypic shifts in tumor-infiltrating immune cells.
  • Identified METTL3 as a central molecular regulator that facilitates tumor immune escape via dual mechanisms: driving intrinsic metabolic reprogramming in tumor cells and reshaping the functions of infiltrating immune cells.
  • Highlighted that METTL3 expression profiles correlate with tumor progression and alter therapeutic response to cancer immunotherapies across diverse hematologic and solid malignancies.
  • Identified high-affinity targeted inhibition of METTL3 and deeper dissection of its immune evasion networks as critical prerequisites for translating METTL3-directed therapies into clinical benefit.
