Emerging epigenetic targets in rheumatoid arthritis

Area of Science:

• Rheumatology
• Epigenetics
• Molecular Biology

Background:

• Rheumatoid arthritis (RA) is a progressive joint disease with largely unknown etiology.
• Both genetic and environmental factors contribute to RA occurrence and progression.
• Epigenetic modifications are increasingly recognized as key players in RA pathogenesis.

Purpose of the Study:

• To review the role of various epigenetic factors in rheumatoid arthritis pathogenesis.
• To summarize potential epigenetic therapies for rheumatoid arthritis.
• To highlight the significance of epigenetic mechanisms in understanding and managing RA.

Main Methods:

• Literature review focusing on epigenetic mechanisms in rheumatoid arthritis.
• Analysis of epigenetic modifications including DNA methylation, histone modification, and miRNA.
• Examination of current and emerging epigenetic therapies and prognostic biomarkers.

Main Results:

• Epigenetic changes like DNA methylation and histone modifications are linked to RA activation and aggressive phenotypes.
• These epigenetic modifications are reversible and can be influenced by external factors.
• Numerous epigenetic therapies are under investigation, showing promise for RA treatment.

Conclusions:

• Epigenetics represents a fundamental cause of heritable phenotypic changes in RA, independent of DNA sequence alterations.
• Targeting reversible epigenetic modifications offers potential for novel RA control and prevention strategies.
• Further research into epigenetic biomarkers and combination therapies may yield synergistic benefits for RA management.
