Epigenetic regulation of alternative splicing

Area of Science:

• Molecular Biology
• Genetics
• Epigenetics

Background:

• Alternative splicing (AS) is a post-transcriptional regulatory mechanism.
• AS generates multiple mRNA transcripts from a single primary transcript.
• AS is influenced by epigenetic regulation and RNA modifications.

Purpose of the Study:

• To review recent advancements in the epigenetic regulation of alternative splicing.
• To highlight the interplay between transcription, epigenetics, and AS.
• To discuss the role of noncoding RNAs (ncRNAs) and RNA modifications in AS.

Main Methods:

• Literature review of recent research on epigenetic regulation of AS.
• Analysis of studies investigating DNA methylation and histone modifications in AS.
• Examination of the role of long noncoding RNAs (lncRNAs) and m6A modifications in AS.

Main Results:

• Epigenetic mechanisms like DNA methylation and histone modifications are coupled with transcription to regulate AS.
• Noncoding RNAs, particularly lncRNAs, can act as splicing factors influencing AS.
• RNA modifications, such as N6-methyladenosine (m6A), have emerged as regulators of AS.

Conclusions:

• Epigenetic regulation plays a significant role in controlling alternative splicing.
• RNA modifications represent a novel layer of regulation for AS.
• Understanding these regulatory networks is crucial for comprehending gene expression complexity.
