HSPD1 and rheumatoid arthritis: RNA-Seq expression for HSPD1 (gene name for HSP60) within synovial tissue was compared between the lympho-myeloid, diffuse-myeloid, and pauci-immune fibroid histological groups in patients with early or established RA using bulk RNA-Seq data generated by us from synovial biopsies obtained as part of the Pathobiology of Early Arthritis Cohort (PEAC) study and the R4RA randomized clinical trial (26–28).
