Functional interaction between long non-coding RNA and microRNA in rheumatoid arthritis

Area of Science:

• Molecular Biology
• Genetics
• Immunology

Background:

• MicroRNAs (miRNAs) are well-understood for roles in cell processes and autoimmune diseases.
• Long non-coding RNAs (lncRNAs) mechanisms are less understood, particularly their interactions with miRNAs.
• Rheumatoid arthritis (RA) is a significant autoimmune disease with complex molecular underpinnings.

Purpose of the Study:

• To review the definition and function of lncRNAs.
• To summarize lncRNA-miRNA interactions relevant to rheumatoid arthritis (RA).
• To highlight research progress in understanding these interactions for RA pathogenesis.

Main Methods:

• Literature review of lncRNA and miRNA research.
• Focus on specific lncRNA-miRNA interactions in the context of RA.
• Analysis of published data on gene expression and molecular mechanisms.

Main Results:

• lncRNAs and miRNAs are key players in cellular processes relevant to RA.
• Specific interactions like HOTAIR/miR138, ZFAS1/miR-27a, and GAPLINC/miR-575 are identified.
• Expression patterns of miRNAs (miR-16, miR-146a, miR-155, miR-223) are noted in RA.

Conclusions:

• lncRNA-miRNA interactions are crucial for understanding RA pathogenesis.
• These interactions represent promising avenues for developing new RA biomarkers.
• Targeting lncRNA-miRNA pathways could lead to novel therapeutic strategies for RA.
