Project description:Genome-wide DNA methylation level was studied to determine whether Rheumatoid arthritis patients (cases) has methylation differences comparing to normal controls in peripheral blood leukocytes (PBLs). We used Illumina HumanMethylation450 BeadChip array to determine the genome-wide DNA methylation difference in PBLs from Rheumatoid arthritis patients (cases) and normal controls
Project description:Leukocytapheresis((LCAP) is a safe, unique therapy prevalent for intractable rheumatoid arthritis even in case of drug allergy or infectious state. To investigate how to improve LCAP efficacy, we have conducted genes expressions analysis from peripheral blood of Rheumatoid arthritis patients using high resolution DNA microarray just before and after LCAP procedure.
Project description:Leukocytapheresis((LCAP) is a safe, unique therapy prevalent for intractable rheumatoid arthritis even in case of drug allergy or infectious state. To investigate how to improve LCAP efficacy, we have conducted genes expressions analysis from peripheral blood of Rheumatoid arthritis patients using high resolution DNA microarray just before and after LCAP procedure. 8 Rheurmatoid arthritis patients have been compared just before and after Leukocytapheresis treatment (overall 16 samples). The Pre-LCAP samples were labeled using Cy5, and the Post-LCAP labeled with Cy3.
Project description:Genome wide DNA methylation profiling of rheumatoid arthritis (RA) patients and healthy controls. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles in peripheral blood mononuclear cells (PBMCs). Samples included 25 RA patients and 18 healthy controls.
Project description:Our goal was to find correlations between gene expression patterns and impaired vascular pathophysiolgy in rheumatoid arthritis Patients with rheumatoid arthritis were recruited and venous blood samples were collected, then peripheral blood mononuclear cells were separated. After RNA isoltaion, we used Affymetrix PrimeView arrays to obtain whole gene expression data.
Project description:CD14+ monocytes sorted from the synovial fluid or peripheral blood of rheumatoid arthritis patients were analyzed by full transcriptome microarray analysis. Monocytes from healthy control samples (peripheral blood) were also profiled.
Project description:Paired synovial and peripheral blood CD14+ cells were obtained from patients with active rheumatoid arthritis and compared to each other
Project description:Genome wide microRNA profiling in peripheral blood mononuclear cells from rheumatoid arthritis (RA) patients and healthy controls. The Affymetrix miRNA 4.0 chip was used to obtain RNA profiles in 28 RA patients and 18 healthy controls.
Project description:In order to identify new biomarkers for the diagnosis of rheumatoid arthritis, we used circRNA microarray technology to screen the differential expression of circRNA in peripheral blood mononuclear cells of patients with rheumatoid arthritis. We identified a total of 399 differentially expressed circRNAs in RA patients and healthy controls, of which 149 circRNAs were significantly up-regulated in RA patients and 250 were down-regulated. Among them, hsa_circRNA_101328 may be a potential biomarker for the diagnosis of RA.
