(Submitter supplied) We have compared synovial biopsies from ankylosing spondylitis and undifferentiated spondylitis patients with healthy controls and osteoarthritis patients Objective: In spondylarthropies, whole-genome gene expression profiling studies have been limited to peripheral blood to date. By undertaking a study in knee synovial biopsies from spondylarthropy (SpA) and ankylosing spondylitis (AS) patients we aimed to identified joint-specific candidate genes and pathways. more...

(Submitter supplied) The aim of this study was to compare the gene expression pattern of synovial cells from inflammatory (I) or normal/reactive (N/R) areas of a synovial membrane harvested from the same osteoarthritis (OA) patient. This study is the first to identify different expression pattern between two areas of the synovial membrane in the same patient. These differences concern several key pathways involved in OA pathogenesis (inflammation, cartilage metabolism, Wnt signaling and angiogenesis). more...

(Submitter supplied) Rheumatoid arthritis (RA) is an inflammatory joint disorder that results in progressive joint damage when insufficiently treated. In order to prevent joint destruction and functional disability in RA, early diagnosis and initiation of appropriate treatment with Disease-Modifying Antirheumatic Drugs (DMARDs) is needed. However, in daily clinical practice, patients may initially display symptoms of arthritis that do not fulfil the classification criteria for a definite diagnosis of RA, or any other joint disease, a situation called “Undifferentiated Arthritis” (UA). more...

(Submitter supplied) Objective: Rituximab displays therapeutic benefits in the treatment of rheumatoid arthritis (RA) patients resistant to TNF blockade. However, the precise role of B cells in the pathogenesis of RA is still unknown. In this study we investigated the global molecular effects of rituximab in synovial biopsies obtained from anti-TNF resistant RA patients before and after administration of the drug. Methods: Paired synovial biopsies were obtained from the affected knee of anti-TNF resistant RA patients before (T0) and 12 weeks after initiation of rituximab therapy (T12). more...

Analysis of synovial biopsy samples from anti-TNF resistant rheumatoid arthritis (RA) patients 12 wks after the start of rituximab (RTX) therapy. RTX is a mAb against CD20, expressed on subsets of B cells. Results provide insight into how RTX-induced B cell depletion interferes with RA pathogenesis.

(Submitter supplied) Introduction: A number of genetic-association studies have identified genes contributing to AS susceptibility but such approaches provide little information as to the gene activity changes occurring during the disease process. Transcriptional profiling generates a “snapshot” of the sampled cells activity and thus can provide insights into the molecular processes driving the disease process. We undertook a whole-genome microarray approach to identify candidate genes associated with AS and validated these gene-expression changes in a larger sample cohort. more...

(Submitter supplied) Background. Rheumatoid arthritis (RA) is a chronic inflammatory and destructive joint disease, characterized by overexpression of pro-inflammatory/-destructive genes and other activating genes (e.g., proto-oncogenes) in the synovial membrane (SM). The gene expression in disease is often characterized by significant inter-individual variances via specific synchronization/ desynchronization of gene expression. more...

(Submitter supplied) We hypothesized that patients with sarcoidosis have characteristic mRNA profiles. Microarray analysis of gene expression was done on peripheral blood. Comparing peripheral blood from patients with sarcoidosis to controls, 872 transcripts were upregulated and 1039 were downregulated at >1.5-fold change and a significant q value. Several transcripts associated with interferon and STAT1 were upregulated. more...

(2) Identify novel osteoporotic (OP) bone-related disease genes. Study involved comparison of trabecular bone extracted from the intertrochanteric (IT) region of the proximal femur (PF) from OA, OP and normal/control (CTL) individuals. Bone was obtained from OA and OP individuals at surgery for total hip replacement and from CTL individuals at autopsy. more...

(Submitter supplied) 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. more...

(Submitter supplied) A focussed microarray chip was constructed specifically for studying basal colonic gene expression in patients with Spondyloarthropathy (SpA) and Crohn's disease (CD) (ref: PMID 16476712). These focus microarrays were used 1) to study common changes in gene expression between SpA and CD, providing early markers in the follow-up study of patients with SpA and particularly these patients that evolve into clinically overt CD; and 2) to identify new candidate genes for CD by integrating gene expression data with genetic information. more...

(Submitter supplied) OBJECTIVES: Ankylosing spondylitis (AS) is unique in its pathology where inflammation commences at the entheses before progressing to an osteoproliferative phenotype generating excessive bone formation that can result in joint fusion. The underlying mechanisms of this progression are poorly understood. Using the proteoglycan-induced spondylitis mouse (PGISp) model which displays spondylitis and eventual joint fusion following an initial inflammatory stimulus, we have characterised the structural and molecular changes that underlie disease progression METHODS: PGISp mice were characterised 12 weeks after initiation of inflammation using expression profiling. more...
