Objective:

To identify potential genetic biomarkers that can differentiate rheumatoid arthritis (RA) from osteoarthritis (OA).

Key Findings:
  • EPYC, MAGED1, and LAP3 are potential biomarkers for distinguishing RA from OA.
  • Diagnostic performance of the identified genes was strong, with AUC values above 0.85.
  • The support vector machine model achieved approximately 93% accuracy.
Interpretation:

The findings suggest that the identified genes may reflect immune activity in joint tissue, aiding in the differentiation of RA from OA.

Limitations:
  • Small sample sizes and reliance on cross-sectional transcriptomic data limit causation establishment.
  • Experimental validation was restricted to messenger RNA expression in a single cell model.
  • Drug sensitivity analyses were based on cancer cell data, which may not accurately represent RA responses.
Conclusion:

Further validation in independent clinical cohorts and mechanistic studies is necessary before clinical application of these biomarkers.
