Project description:CD14+ monocytes sorted from the synovial fluid or peripheral blood of rheumatoid arthritis patients were analyzed by full transcriptome microarray analysis. Monocytes from healthy control samples (peripheral blood) were also profiled.
Project description:To understand the pathogenic mechanisms of bone erosion in rheumatoid arthritis (RA), we investigated osteoclast-specific epigenetic programs, RANKL-responsive super-enhancers (SEs) and SE-associated enhancer RNAs (SE-eRNAs) in human osteoclasts. In this dataset, we sought for functional SE-eRNAs in RA patients' synovial monocytes.
Project description:Rheumatoid arthritis (RA) is a complex and clinically heterogeneous autoimmune disease. Microarray analysis of 83 synovial samples provides insight into the expression-level differences between patients at the site of disease activity. Synovial samples from Rheumatoid Arthritis patients were obtained during joint resection and profiled using microarrays.
Project description:Rheumatoid arthritis (RA), a chronic and systemic disease of unknown etiology, is characterized by hyperplasia of synovial cells, which ultimately lead to the destruction of cartilage and bone. To elucidate the molecular mechanisms that lead to RA, we analyzed synovial cells established from patient with RA by oligonucleotide microarrays. Gene expression profiles reveal a novel pathophysiologic function of RA synovial cells as a generator of oxidative stress, and a self-defense mechanism against self-generated oxidative stress. Experiment Overall Design: We isolated synovial cell culture from patients with rheumatoid arthritis and osteoarthritis. Fibroblast from patient with osteoarthritis was used for the reference.
Project description:Synovial biopsies from rheumatoid arthritis patients were obtained and profiled using RNA-seq. Patients were stratified according to the number of swollen joints they had (SJC, swollen joint count) and divided in three groups for the differential expression analysis: None (SJC = 0), Low (1<= SJC <= 8), High (SJC > 8).
Project description:Synovial biopsies from rheumatoid arthritis patients were obtained and profiled using bisulfite-seq for whole-genome DNA methylation. Patients were stratified according to the number of swollen joints they had (SJC, swollen joint count) and divided in three groups for the differential expression analysis: None (SJC = 0), Low (1<= SJC <= 8), High (SJC > 8).
Project description:mRNA expression levels in synovial fibroblasts in 6 rheumatoid arthritis patients versus 6 osteoarthritis patients. Experiment Overall Design: Synovial tissue was obtained from open joint replacement surgery or Experiment Overall Design: arthroscopic synovectomy. Patients with RA or OA (n = 6 each for gene expression analysis and further patients for validation experiments) were classified according to the ACR criteria.
Project description:We report changes in gene expression that take place in human neutrophils following migration from peripheral blood to synovial joints in patients with rheumatoid arthritis
Project description:Rheumatoid arthritis (RA) is a chronic autoinflammatory disorder that affects small joints. Despite intense efforts, there isno definitive marker yet for early diagnosis RA and for monitoring the progression of this disease. We sought to catalog the proteins present in the synovial fluid of patients with rheumatoid arthritis. To identify lower abundance proteins, we undertook two approaches – we depleted the abundant proteins using a multiple affinity removal system (MARS14) column and we enriched glycoproteins using a lectin affinity column. The peptides were analyzed by LC-MS/MS on a high resolution Fourier transform mass spectrometer.
