Long Noncoding RNAs: Insights from Biological Features and Functions to Diseases

Area of Science:

• Molecular Biology
• Genomics
• Epigenetics

Background:

• Genome-wide transcriptomic studies reveal pervasive transcription, producing numerous non-protein-coding RNAs.
• This challenges the protein-centric view of cellular functions and RNA's role as a mere intermediary.
• Long noncoding RNAs (lncRNAs) are a key class of these transcripts with complex regulatory roles.

Purpose of the Study:

• To review the biological features and functions of lncRNAs.
• To highlight lncRNA roles in gene expression regulation, stem cell pluripotency, morphogenesis, and development.
• To discuss the medical implications and therapeutic potential of lncRNAs.

Main Methods:

• Literature review of recent research on lncRNAs.
• Analysis of transcriptomic data and functional studies.
• Synthesis of findings on lncRNA-mediated gene regulation.

Main Results:

• lncRNAs exhibit specific spatial and temporal expression patterns.
• They play significant roles in regulating gene expression.
• lncRNAs are implicated in stem cell pluripotency, development, and disease processes.

Conclusions:

• lncRNAs represent a complex layer of gene regulation beyond protein-coding genes.
• Understanding lncRNA function is crucial for deciphering cellular processes.
• lncRNAs hold promise for disease diagnostics and therapeutic interventions.
