m⁶A Modification in Mammalian Nervous System Development, Functions, Disorders, and Injuries

Area of Science:

• Neuroscience and Epigenetics
• Molecular Biology and RNA Modifications

Background:

• N6-methyladenosine (m6A) is the most prevalent internal modification on mRNA, influencing gene expression.
• m6A modification is highly enriched in the mammalian brain, suggesting a key role in nervous system regulation.
• Epitranscriptomic regulation via m6A offers a new layer of control in neurological processes.

Purpose of the Study:

• To review recent advancements in understanding m6A modification in the mammalian nervous system.
• To elucidate the mechanisms of m6A modification in neuronal development and brain functions.
• To discuss the role of dysregulated m6A in neurological disorders and injuries.

Main Methods:

• Comprehensive literature review of studies on m6A modification in the mammalian nervous system.
• Analysis of the roles of m6A 'writers', 'erasers', and 'readers' in neural processes.
• Examination of evidence linking m6A dysregulation to neurological conditions.

Main Results:

• m6A modification is integral to various aspects of the nervous system, from development to complex brain functions.
• Specific m6A regulators (writers, erasers, readers) mediate distinct biological processes.
• Aberrant m6A patterns are associated with the pathogenesis of neurological disorders and injuries.

Conclusions:

• m6A epitranscriptomic regulation is a critical determinant of nervous system function.
• Understanding m6A mechanisms provides insights into neuronal development, function, and disease.
• Targeting m6A pathways may offer therapeutic strategies for neurological disorders.
