Abstract:
N6-methyladenosine (m6A) is the most abundant post-transcription modification, widely occurring in eukaryotic mRNA and non-coding RNA. m6A modification is highly enriched in the mammalian brain and is associated with neurological diseases like Alzheimer's disease (AD) and Parkinson's disease (PD). Ischemic stroke (IS) was discovered to alter the cerebral m6A epi-transcriptome, which might have functional implications in post-stroke pathophysiology. Moreover, it is observed that m6A modification could regulate microglia's pro-inflammatory and anti-inflammatory responses. Given the critical regulatory role of microglia in the inflammatory processes in the central nervous system (CNS), we speculate that m6A modification could modulate the post-stroke microglial inflammatory responses. This review summarizes the vital regulatory roles of m6A modification in microglia-mediated inflammation and IS. Stroke is associated with a high recurrence rate, understanding the relationship between m6A modification and stroke may help stroke rehabilitation and develop novel therapies in the future.
Insights
N6-methyladenosine (m6A) RNA modification regulates brain inflammation in ischemic stroke (IS). Understanding m6A
Area of Science:
- Neuroscience
- Molecular Biology
- Epigenetics
Background:
- N6-methyladenosine (m6A) is the most prevalent RNA modification in eukaryotes.
- m6A is abundant in the brain and linked to neurological disorders like Alzheimer's and Parkinson's disease.
- Ischemic stroke (IS) impacts the brain's m6A landscape, potentially influencing stroke pathophysiology.
Purpose of the Study:
- To review the regulatory roles of m6A modification in microglia-mediated inflammation.
- To explore the connection between m6A, microglia, and IS.
