Cellular Communication Network Factor 3 contributes to the pathological process of rheumatoid arthritis via promoting cell senescence in synovial cells

Project description:Cellular Communication Network Factor 3 (CCN3) is a secreted protein. It belongs to the CCN family of regulatory proteins, which play essential roles in various cellular processes. In this study, we investigated the functional characteristics of CCN3 in rheumatoid arthritis. We found CCN3 is involved in cellular senescence and inflammation of fibroblast like synoviocyte (FLS) in vitro. To understand this mechanism, CCN3 is were added to FLS and their responses were examined by bulk-RNA analysis.

Expression data from Rheumatoid Arthritis synovial tissue samples

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.

It belongs to the CCN family of regulatory proteins, which play essential roles in various cellular processes. In this study, we investigated the functional characteristics of CCN3 in rheumatoid arthritis. We found CCN3 is involved in cellular senescence and osteoclastgenesis of macrophage in vitro. To understand this mechanism, CCN3 is were added to Macrophage and their responses were examined by bulk-RNA analysis.

Synovial fluid proteome in 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.

Transcriptional analysis of normal and pathological synovial fibroblasts

Project description:The aim of this study was to compare gene expression between two pathological groups of human synovial fibroblasts (SF) from rheumatoid arthritis (RA) and osteoarthritis (OA) synovial tissues with normal SF from healthy individuals (HSF). We used microarray expression profiling in SF cultured from OA, RA and normal synovial tissues. We found larger numbers of transcripts with differential expression in OASF compared to the other groups than in RASF compared to HSF. This data demonstrate that cultured OASF display a more robust transcriptomic profile than RASF when compared to HSF. Synovial fibroblasts were obtained from 9 patients with rheumatoid arthritis (RASF), 11 sex and age matched adult healthy donors (HSF) and 11 sex and age matched patients with OA (OASF). SF were collected under similar subconfluent conditions 24h after serum addition. 31 microarray data were used for determine the statistical significance (p value) of the differences in gene expression.

Transcription profiling of human synovial cells isolated from patients with rheumatoid arthritis

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.

Synovial biopsies of rheumatoid arthritis and healthy controls

Project description:Synovial biopsies were obtained from rheumatoid arthritis (RA) synovium and from subjects without a joint disease to find gene upregulated during RA. The promoters of genes upregulated during RA compared to HC can be used to obtain disease-regulated gene therapy.

Indentification of special gene expressions in synovial tissues of rheumatoid arthritis

Project description:Gene expression microarray was applied to discover novel rheumatoid arthritis (RA)-specific gene expressions by comparing the expression profiles of synovial membranes from patients with RA, osteoarthritis (OA) and ankylosing spondylitis (AS). We performed a gene expression microarray analysis of RA synovial membranes and simultaneously compared the expression profile with the profiles of AS and OA synovial membranes.
