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:Genome-wide DNA methylation level was studied to determine whether Rheumatoid arthritis patients (cases) has methylation differences comparing to normal controls in 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 Bisulphite converted DNA from the Rheumatoid arthritis patients (cases) and normal controls were hybridized to the Illumina Illumina HumanMethylation450 BeadChip arrays
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:Rheumatoid arthritis (RA) is a chronic, inflammatory joint disease of unknown etiology and pronounced inter-patient heterogeneity. To characterize RA at the molecular level and to uncover key pathomechanisms, we performed whole-genome gene expression analyses. Synovial tissues from rheumatoid arthritis patients were compared to those from osteoarthritis patients and to normal donors. Keywords: disease state analysis Two disease conditions (rheumatoid arthritis and osteoarthritis) in comparison to normal donors were investigated. For the two disease groups samples derived from three individual patients and two pools of patients were hybridised.
Project description:Targeted bisulphite pyrosequencing of the major histocompatibility complex (MHC) region was performed using CATCH-Seq kits on whole blood DNA isolated from healthy controls and patients with rheumatoid arthritis. Data analysis showed 74 unique and differentially methylated loci (DMLs) in the MHC region of RA patients compared to healthy controls. Further, differentially methylated CpGs in C6orf10 gene were negatively associated with preclinical RA risk factors.
