Long Non-Coding RNA Epigenetics.

Area of Science:

• Molecular Biology
• Epigenetics
• RNA Biology

Background:

• Long noncoding RNAs (lncRNAs) are crucial for cellular functions and organism development.
• Gene expression is further regulated by lncRNA epigenetics, involving modified nucleosides.
• Common modified nucleosides in lncRNA include 6-methyladenosine, 5-methylcytidine, pseudouridine, and inosine.

Purpose of the Study:

• To review the epigenetic regulation of lncRNAs through modified nucleosides.
• To describe the biosynthetic pathways and enzymes involved in lncRNA nucleoside modification.
• To discuss methods for detecting modified nucleosides in lncRNAs and their functional roles.

Main Methods:

• Literature review of lncRNA epigenetics.
• Description of writer, eraser, and reader enzymes.
• Overview of detection methods for modified nucleosides in lncRNAs.

Main Results:

• Detailed characterization of key modified nucleosides (m6A, m5C, Ψ, I).
• Explanation of biosynthetic pathways and enzyme functions.
• Discussion of advantages and disadvantages of detection methods.

Conclusions:

• lncRNA epigenetics represents a significant layer of gene expression control.
• Modified nucleosides play critical roles in the functions of abundant lncRNAs.
• Dysregulation of lncRNA modifications is implicated in pathogenic processes.
