RNA sequencing was performed on peripheral blood mononuclear cells from ACPA-positive and ACPA-negative rheumatoid arthritis patients and healthy controls. The study identified C-X-C motif chemokine ligand 2 (CXCL2) as significantly upregulated in ACPA-positive RA and validated its role in promoting osteoclastogenesis via ERK MAPK and NFκB pathways. The dataset was generated by researchers at Peking University and is available via Open Access.
Use Cases
- Identify differentially expressed genes between ACPA-positive and ACPA-negative RA based on RNA-seq data.
- Investigate candidate biomarkers for RA disease subsets based on transcriptome analysis of PBMCs.
- Study the role of chemokines like CXCL2 in osteoclastogenesis and bone erosion in RA.
- Validate gene expression signatures using PCR and ELISA data from a separate cohort.
- Explore correlations between gene expression and clinical/laboratory data from RA patients.
Strengths
- Includes a validation cohort with PCR and ELISA data to confirm RNA-seq findings.
- Links gene expression findings to a specific biological mechanism (osteoclastogenesis) and clinical outcome (bone erosion).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
