Project description:Autoimmune diseases, such as rheumatoid arthritis, are associated with significant gut microbiota dysbiosis. Here we show that remodelling of 24h rhythms within the gut during inflammatory joint disease drives profound changes in the microbiome and gut permeability.

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: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:Intent of this experiment is to define the baseline transcriptome of the synovium obtained from rheumatoid arthritis patients prior to initiation of DMARD (Disease-modifying antirheumatic drug) therapy and compare it with the synovial transcriptome of rheumatoid arthritis patients with an established disease profile.
Project description:Rheumatoid arthritis (RA) is a complex and clinically heterogeneous autoimmune disease. Microarray analysis of 83 synovial samples provides insight into the expression-level differences between patients at the site of disease activity. Synovial samples from Rheumatoid Arthritis patients were obtained during joint resection and profiled using microarrays.

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 to normal donors. Keywords: repeat sample Rheumatoid in comparison to normal donors were investigated. For both groups samples derived from individual patients and or pools of patients were hybridised.
Project description:We screened the differential expressed microRNA from the rheumatoid arthritis patients and healthy person in their hydrops articuli CD4+ T cells. We screened the differential expressed microRNA from the rheumatoid arthritis patients and healthy person in their hydrops articuli CD4+ T cells. 1.Isolated the CD4+ T cells from the hydrops articuli cells of 2 rheumatoid arthritis patients. 2.Isolated the CD4+ T cells from healthy person's peripheral blood as control. 3.Isolation of total RNA from CD4+ T cells then sent the samples to KangChen Bio-tech Inc (Shanghai, China) where they were labeled, hybridized, scaned, normalied and transformed to the final data.
