(Submitter supplied) Stratifying patients on the basis of molecular signatures could facilitate development of therapeutics that target pathways specific to a particular disease or tissue location. Previous studies suggest that pathogenesis of rheumatoid arthritis (RA) is similar in all affected joints. Here we show that distinct DNA methylation and transcriptome signatures not only discriminate RA fibroblast-like synoviocytes (FLS) from osteoarthritis FLS, but also distinguish RA FLS isolated from knees and hips. more...

(Submitter supplied) Rheumatoid arthritis (RA) fibroblast‐like synoviocytes (FLS) derived from hip and knee have distinctive DNA methylation and transcriptome patterns in interleukin (IL)‐6 signaling and Janus kinase (JAK)–signal transducers and activators of transcription (STAT) pathways. To determine the functional effects of these joint‐specific signatures, we evaluated how RA hip and knee FLS differ in their response to IL‐6.Hip or knee RA FLS were obtained after arthroplasty. more...

(Submitter supplied) Objectives: Epigenetics can influence disease susceptibility and severity. While DNA methylation of individual genes has been explored in autoimmunity, no unbiased systematic analyses have been reported. Therefore, a genome-wide evaluation of DNA methylation loci in fibroblast-like synoviocytes (FLS) isolated from the site of disease in rheumatoid arthritis (RA) was performed. Methods: Genomic DNA was isolated from six RA and five osteoarthritis (OA) FLS lines and evaluated using the Illumina HumanMethylation450 chip. more...

(Submitter supplied) Epigenetics is important in the pathogenesis of immune-mediated diseases like rheumatoid arthritis (RA). Here we show the first complete epigenomic characterization of RA fibroblast-like synoviocytes (FLS) by profiling histone modifications (H3K27ac, H3K4me1, H3K4me3, H3K36me3, H3K27me3, H3K9me3), open chromatin, RNA expression and whole genome DNA methylation. To address the complex multidimensional relationship and reveal the epigenetic regulation of RA, we perform integrative analyses using a novel unbiased method to identify genomic regions with similar profiles. more...

(Submitter supplied) Transcriptional profiling of mouse chondrocytes comparing chondrocytes infected with empty adenovirus and Epas1 adenovirus. RNA was extracted from each chondrocytes. We used microarrays to determine the effect of Epas1 overexpression on chondrocytes and identify the noble regulatory molecules during osteoarthritic pathogenesis.

(Submitter supplied) Discrimination of rheumatoid arthritis (RA) patients from patients with other inflammatory/degenerative joint diseases or healthy individuals purely on the basis of genes differentially expressed in high-throughput data has proven very difficult. Thus, the present study sought to achieve such discrimination by employing a novel unbiased approach using rule-based classifiers. Three multi-center genome-wide transcriptomic data sets (Affymetrix HG- U133 A/B) from a total of 79 individuals, including 20 healthy controls (control group - CG), as well as 26 osteoarthritis (OA) and 33 RA patients, were used to infer rule- based classifiers to discriminate the disease groups. more...

(Submitter supplied) At a given time, rheumatoid arthritis (RA) is a heterogeneous disease and its underlying molecular mechanisms is still poorly understood. Because previous microarrays studies have only focused on late RA stages, we aimed to compare the biological and molecular profiles in early and long-standing (LS) RA. Synovial biopsies obtained by arthroscopy were performed in 4 early untreated RA patients, 4 LS treated RA patients and 7 control patients. more...
