Optimized “In Vitro” Culture Conditions for Human Rheumatoid Arthritis Synovial Fibroblasts
The composition of synovial fluid in rheumatoid arthritis (RA) is complex and strongly influences the microenvironment of joints and it is an inseparable element of the disease. Currently, "in vitro" studies are performed on RA cells cultured in the presence of either recombinant proinflammatory cytokines-conditioned medium or medium alone. In this study, we evaluated the use of synovial fluid,...
متن کاملMicrosatellite analysis in rheumatoid arthritis synovial fibroblasts.
OBJECTIVES Rheumatoid arthritis (RA) is a chronic disease characterised by irreversible destruction of the affected joints. As aggressive transformed-appearing synovial fibroblasts are commonly found at the site of invasion of the rheumatoid synovium into the adjacent cartilage and bone, the presence of microsatellite instability (MSI) and expression of mismatch repair enzymes as a possible mec...
متن کاملCell culture and passaging alters gene expression pattern and proliferation rate in rheumatoid arthritis synovial fibroblasts
INTRODUCTION Rheumatoid arthritis synovial fibroblasts (RASF) are key players in synovial pathophysiology and are therefore examined extensively in various experimental approaches. We evaluated, whether passaging during culture and freezing has effects on gene expression and cell proliferation. METHODS RASF were passaged for up to 8 passages. RNA was isolated after each passage and cDNA array...
متن کاملp53 in rheumatoid arthritis synovial fibroblasts at sites of invasion.
OBJECTIVE To analyse the functional response of p53 in rheumatoid arthritis synovial fibroblasts (RASF) in vitro and in vivo and to investigate whether activation of p53 modulates the destructive process of RASF. METHODS RASF and controls grown on chamber slides were either directly examined with DO7 anti-p53 antibodies by immunofluorescence or irradiated with 10 Gy x rays and analysed time d...
متن کاملMicroRNAs interfere with DNA methylation in rheumatoid arthritis synovial fibroblasts
BACKGROUND The DNA of rheumatoid arthritis synovial fibroblasts (RASF) is globally hypomethylated; this contributes to an aggressive behaviour. In an attempt to remethylate these cells, we supplemented with methyl donors. We investigated the possible interference of microRNAs (miRs). MATERIAL AND METHODS RASF were treated with L-methionine or betaine. Transcripts of de novo methyltransferases...
