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: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.
Project description:Synovial biopsies of Rheumatoid Arthritis patients were obtained at week 20 of anti-TNF therapy. The clinical response to therapy was determined comparing the DAS28 at this time point with the baseline DAS28, using the EULAR response criteria. Gene expression profiles of patients responding to anti-TNF therapy were compared to non-responders and different genes, pathways and deconvoluted cell types were found to be differential between both groups of rheumatoid arthritis patients.
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.
