Laser Capture Microscopy RNA Sequencing for Topological Mapping of Synovial Pathology During Rheumatoid Arthritis
Authors' conclusion
LCM-RNAseq confirms reported transcriptional differences between the RA synovium and the OA synovium and provides evidence supporting a relationship between synovial topology and molecular anomalies in RA.
Study context
- Population
- Synovial lining, sublining and vessel samples from patients with rheumatoid arthritis (RA) and osteoarthritis (OA)
- Comparison
- RA vs OA synovium
- RAn = seven
- OAn = sevenreference
- Outcome
- Regional synovial transcriptomes, RA vs OA

Main finding
As reported in the abstract
- RA and OA transcriptomes distinguishable by principal component analysis
- Substantial differences in transcriptional patterns between RA and OA in lining, sublining and vessel samples
- Hierarchical clustering of pathways showed association between biologic function and synovial topology
- RA lining: anomalous immune cell signaling
- RA sublining: aberrant cell cycle
- RA vessel: alterations in heme scavenging
