(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) Primary open angle glaucoma (POAG) is a progressive optic neuropathy, which is a major cause of worldwide visual impairment and blindness. Pathological hallmarks of the glaucomatous optic nerve head include retinal ganglion cell axon loss and extracellular matrix (ECM) remodeling of the lamina cribrosa layer. TGF-beta is an important pro-fibrotic modulator of ECM metabolism, whose levels are elevated in human POAG lamina cribrosa tissue compared with non-glaucomatous controls. more...

(Submitter supplied) Rheumatoid arthritis synovial fibroblasts (RASF) were transected with an adenovirus (Ad) expressing a dominant negative (DN) form of Ik-B stimulated 18 hours later with TNF-a. Controls were RASF transfected with Adtet then treated with TNF-a 18 hours later. RNA was extracted 3 hours after TNF-a application. The same cell line was split into 6 lots grown up and then treated with the virus independent. more...

(Submitter supplied) CD34+ hematopoietic stem/progenitor cells were isolated from human cord blood and amplified in vitro for 10-14 days in serum-free medium with specific cytokines (Ju et al., Eur. J. Cell Biol. 82, 75-86, 2003; Hacker et al., Nat. Immunol. 4, 380-386, 2003). Cultured progenitor cells were induced to differentiate into DC in RPMI medium supplemented with 10% fetal calf serum, 2 mM L-glutamine, 0.1 microM Beta-mercaptoethanol, 100 U/ml penicillin and streptomycin (GIBCO-BRL) and 500 U/ml GM-CSF, 500 U/ml IL-4 for 6 days with or without 10 ng/ml TGF-beta1 as indicated (0.5x10E6 cells/ml). more...

(Submitter supplied) Spots were selected that had an expression level higher than 1.6 the local background. The use of a common reference sample allows the comparison of the relative expression levels across the tissue samples. All genes were expressed relative to their median expression level across the arrays of the same microarray platform, allowing us to combine the data from the 2 platforms. Data from Lymphochip and Stanford Human cDNA arrays was combined per patient. 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) ABSTRACT: Background: Oral Submucous Fibrosis (OSF) is a chronic inflammatory disease resulting in progressive fibrosis of the oral soft tissues. Habit of chewing betel quid has been proposed as an important etiological factor in the development of this disease. But the exact mechanism of pathogenesis is still not clear. Methods: We took microarray approach to identify differentially regulated genes in 10 OSF tissues against 8 pooled normal tissues using oligonucleotide arrays. more...

(Submitter supplied) Pigmented villonodular synovitis (PVNS) represents a rare group of lesions with morphological features suggesting an inflammatory as well as a neoplastic nature. Rheumatoid arthritis (RA) is characterized by a chronic inflammation of the synovial tissue and a tumor-like proliferation (TLP) of synovial stroma cells. Osteoarthritis (OA) shows modest inflammatory infiltrates and no TLP. All three diseases result in a progressive destruction of affected joints and remain a diagnostic difficulty because of nonspecific symptoms. more...

(Submitter supplied) Rheumatoid arthritis (RA) is a heterogeneous disease. We used cDNA microarray technology to subclassify RA patients and disclose disease pathways in rheumatoid synovium. Hierarchical clustering of gene expression data identified two main groups of tissues (RA-I and RA-II). A total of 121 genes were significantly higher expressed in the RA-I tissues, whereas 39 genes were overexpressed in the RA-II tissues. more...

(Submitter supplied) Background Rheumatoid arthritis (RA) is a chronic inflammatory disease, characterized by joint destruction and perpetuated by the synovial membrane (SM). In the inflamed SM, activated synovial fibroblasts (SFB) form the major cell type promoting development and progression of the disease by an abnormal expression/secretion of pro-inflammatory cytokines, tissue-degrading enzymes resulting in a predominant degradation of the extra-cellular matrix (ECM), and collagens causing joint fibrosis. more...

(Submitter supplied) Inflammatory tissues are characterized by low oxigen concentrations (hypoxia). These conditions are very different from that usually present in tissue cultures where transcriptomic profiles of human fibroblasts from inflammatory tissues have been previously analysed. The aim of this study was to characterize the changes on gene expression induced by hypoxia in human synovial fibroblasts. We used microarray expression profiling in paired normoxic and hypoxic cultures of healthy and rheumatoid arthritis (RA) synovial fibroblasts (HSF and RASF). 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...
