Roles for long non-coding RNAs in physiology and disease

Area of Science:

• Genomics
• Molecular Biology
• Gene Regulation

Background:

• The human genome extensively transcribes RNA, but only a small fraction codes for proteins.
• A significant portion of transcribed RNA comprises long non-coding RNAs (lncRNAs).
• Emerging evidence indicates that some lncRNAs possess functional capabilities.

Purpose of the Study:

• To review the functional roles and regulatory mechanisms of long non-coding RNAs.
• To highlight the involvement of lncRNAs in various biological processes and diseases.

Main Methods:

• Literature review of recent studies on lncRNA identification and functional characterization.
• Analysis of lncRNA expression patterns in different physiological and pathological contexts.

Main Results:

• LncRNAs regulate gene expression at both transcriptional and post-transcriptional levels.
• Differentially expressed lncRNAs have been identified in genetic disorders and human diseases.
• Functional roles for specific lncRNAs are established in development, cancer, and tissue homeostasis.

Conclusions:

• LncRNAs represent a crucial layer of gene regulation, contributing to cellular complexity.
• Understanding lncRNA functions is vital for deciphering physiological and disease-related phenotypes.
