Rapid and dynamic transcriptome regulation by RNA editing and RNA modifications.

Area of Science:

• Molecular Biology
• Genetics
• Epigenetics

Background:

• Next-generation sequencing and mass spectrometry reveal widespread messenger RNA (mRNA) modifications and RNA editing.
• These modifications significantly impact mammalian transcriptomes.
• Factors regulating these changes are termed "writers," "erasers," and "readers," analogous to epigenetic terminology.

Purpose of the Study:

• To outline how RNA editing and RNA modification rapidly affect gene expression.
• To highlight the role of epitranscriptomic changes in cellular responses and regulation.

Main Methods:

• The study is a review and outline, synthesizing current knowledge.
• It discusses findings derived from next-generation sequencing and mass spectrometry.

Main Results:

• RNA editing and modification represent a newly appreciated layer of gene expression regulation.
• These epitranscriptomic changes can rapidly alter gene expression.
• They are well-suited for responding to cellular stress and regulating transcriptomes during development or circadian cycles.

Conclusions:

• Epitranscriptomic modifications offer a dynamic mechanism for gene expression control.
• Understanding these processes is key to comprehending cellular responses and developmental regulation.
