Project description:In 15 patients with rheumatoid arthritis the baseline expression (t=0) of type I IFN-regulated genes was determined in peripheral blood cells (PAXgene) using cDNA-microarrays and compared to levels one month after (t=1) anti-TNF treatment (infliximab). Therefore, we used 43K cDNA microarrays from the Stanford Functional Genomics Facility (http://microarray.org/sfgf/) printed on aminosilane-coated slides containing ~20.000 unique genes. Only one batch of arrays was used for all experiments. First DNA spots were UV-cross linked to the slide using 150-300 mJoules. Sample preparation and microarray hybridization were performed as described previously (1,2). Data storage and filtering was performed using the Stanford Microarray Database (http://genome-www5.stanford.edu//) as described previously. 1. van der Pouw Kraan TC, Wijbrandts CA, van Baarsen LG, Voskuyl AE, Rustenburg F, Baggen JM et al.: Rheumatoid arthritis subtypes identified by genomic profiling of peripheral blood cells: assignment of a type I interferon signature in a subpopulation of patients.

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: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

Project description:The transcriptome of PBMC from rheumatoid arthritis patient hasn't been compenhensively profiled, and heterogeneous characteristics of blood monocytes in RA patients are much unknown. We performed the single cell transcriptomic analysis of PBMC from rheumatoid arthritis (RA) patient, and monocyte populations were extracted during the analysis. CD127 expression associated expression pattern of inflammatory genes was identified in RA patient's blood monocytes.

Project description:Trial described in Lancet. 2006 Sep 2;368(9538):855-63. Rheumatoid arthritis patients were treated with chaperonin 10, with a dose of 10 mg rCpn10 i.v. twice weekly for 56 days. Blood samples were collected before and after treatment. Microarray analysis described in Hirata et al., Early pregnancy factor, chaperonin 10 and rheumatoid arthritis; the story unravels.

Project description:Approximately 30% of rheumatoid arthritis patients achieve inadequate response to anti-TNF biologics. In this study, we sought to identify a blood gene expression biomarker correlating with 12-week response to infliximab in patients with moderate to severe disease. Response was assessed using dynamic contrast-enhanced MRI imaging of the wrist. Baseline whole blood samples from 59 patients were collected as part of a placebo-controlled clinical study of infliximab in rheumatoid arthritis. Samples were profiled by Affymetrix microarray and correlation between gene expression and 12-week response was assessed. DAS28 (Disease Activity Score including a 28-joint count)
