Abstract

Insights

N6-Methyladenosine (m6A) plays a key role in ischemic stroke (IS) progression. This review summarizes m6A

Area of Science:

  • Epigenetics and RNA modifications
  • Molecular mechanisms of ischemic stroke

Background:

  • N6-Methyladenosine (m6A) is the most prevalent and reversible mRNA modification.
  • Emerging evidence links m6A modification to the pathogenesis of ischemic stroke (IS).
  • Understanding m6A's role is crucial for developing novel IS therapies.

Purpose of the Study:

  • To review m6A methylation enzymes and their functions.
  • To elucidate the mechanisms of m6A involvement in IS.
  • To explore the potential of m6A as a therapeutic target for IS.

Main Methods:

  • Comprehensive literature review of m6A modification enzymes (methyltransferases, demethylases, binding proteins).
  • Analysis of m6A alterations in IS, including its association with atherosclerosis, IR injury, inflammation, oxidative stress, and apoptosis.
  • Investigation of m6A-associated single-nucleotide polymorphisms (SNPs) in IS.

Main Results:

  • Detailed overview of m6A methyltransferases (METTL3, METTL14, WTAP), demethylases (FTO, ALKBH5), and m6A-binding proteins (YTHDC1/2, YTHDF1/2/3, IGF2BP1/2/3).
  • m6A is differentially expressed in IS, implicating it in key pathological processes.
  • Identification of m6A-associated SNPs as potential causal variants for IS.

Conclusions:

  • m6A modification is intricately involved in the pathogenesis of ischemic stroke.
  • Targeting m6A pathways offers promising therapeutic strategies for IS.
  • Further research into m6A-based therapies is warranted for clinical application.
