Project description:Object: to understand Infliximab treatment effect on the molecular expression of tissue at disease site 4mm punch biopsies were performed on involved and uninvolved skin at baseline in 5 Ps patients. A repeat biopsy was performed at week 2 after IFX therapy at a site adjacent to the baseline biopsy of involved skin. Synovial biopsies were performed on the knee of 3 RA and 3 PsA paired-subjects with a Parker Pearson biopsy needle (Dyna Medical, London, Canada) under ultrasound guidance at baseline and repeated on the same knee at week 10

Project description:objection: The immune inflammatory disorders rheumatoid arthritis (RA), psoriatic arthritis (PsA) and psoriasis (Ps) share common pathologic features and show responsiveness to anti-tumor necrosis factor (TNF) agents yet they are phenotypically distinct. The aim of this study was to examine if anti-TNF therapy is associated with divergent gene expression profiles in circulating cells and target tissues of patients with these diseases Method: Peripheral blood CD14+ and CD14- cells were isolated from 9 RA, 12 PsA and 10 Ps patients before and after infliximab (IFX) treatment.

Project description:All the synovial tissue specimens for TMT relative quantitative proteomics and further experiments were obtained from the patients with RA or OA undergoing surgical joint replacement at the clinical of joint surgery (Xi'an Hong Hui Hospital, Xi'an Jiaotong University, China). The diagnosis of the patients were accorded to the criteria of the American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) in 2010.a quantitative proteomic profiling of synovial tissue obtained from RA and OA patients was carried out by using TMT labeling followed by high resolution mass spectrometry analysis. We have identified 4822 proteins out of which 510 proteins were found to be differentially expressed by ≥1.2 fold change in the synovial tissue from RA verses OA patients.

Between April 2007 and June 2009, 31 patients with active RA, PsA and Ps who were naïve to anti-TNF agents, were recruited from the Faculty Rheumatology Clinics at the University of Rochester Medical Center after informed, written consent was obtained in a protocol approved by the Research Subjects Review Board at the University of Rochester Medical Center. Of the 31 subjects, 9 had active RA and 12 had PsA despite treatment with Disease Modifying Anti-Rheumatic Drugs (DMARDs). Also, 10 patients with extensive Ps (>5% BSA) documented by a dermatologist, were enrolled and they were examined by a rheumatologist to exclude the presence of inflammatory arthritis. Nineteen healthy controls were also recruited.

Project description:We explored transcriptomic profiles of paired synovial biopsies from RA patients, in order to assess heterogeneity in synovial tissue at the individual level. Pairwise comparison of transcriptomic profiles showed similar expression of RA-related molecular pathways (TCR signaling, T cell co-stimulation and response to TNF⍺), thereby showing that global molecular alterations in RA synovitis are similar between small and large joints from the same patient.

Project description:In the current study, we compared DNA methylation patterns using the Illumina 850k array technology between normal synovial fibroblasts and synovial fibroblasts from early (veRASF) and late stages of RA (estRASF) and transient, resolving arthritis (rSF). In doing so, we obtained a detailed view of changes in DNA methylation that occur during the development of RA from the earliest clinically apparent stages to established RA with its typical signs and symptoms.
