Project description:Knee joint synovium was used for gene expression analysis of mouse collagen induced arthritis (CIA). Synovium was prepared at day 30 after initial sensitization from: healthy controls, CIA animals with no, with mild, with moderate, or with severe joint inflammation. Each sample group is represented by three replicates, each consisting of tissue collected from three to four animals. Experiment Overall Design: The data set consists of 15 samples: five groups with three replicates each. One sample group is from healthy controls, the other groups are from CIA animals with different degress of joint inflammation.

Project description:This study investigated the systemic effects of 0.1 THz irradiation on the inflammatory status of rheumatoid arthritis (RA) in the collagen-induced arthritis (CIA) mouse model. It was found that THz irradiation apparently alleviated the symptoms of arthritis in CIA mice, reducing the joint swelling, mitigating the tissue damage and relieving the expression of pro-inflammatory factors (TNF-, IL-6, RANKL and MMPs) in the swollen joint of the CIA mice. Moreover, the reduction of serum inflammatory cytokines levels together with the reduced CD4+ T cell count and the recovered percentage of regulatory T cells (Treg) indicated that THz irradiation exerted a systemic immunoregulatory activity in CIA mice. The blood leukocyte mRNA-seq GO analysis also enriched several biological processes including the differentiation and adhesion of leukocytes, lymphocyte differentiation and T cell activation, providing additional supporting evidence for the immunoregulatory effects of THz.
Project description:Oxylipins play important roles in various biological processes and are considered as mediators of inflammation for a wide range of diseases such as rheumatoid arthritis (RA). The purpose of this research was to study differences in oxylipin levels between a widely used collagen-induced arthritis (CIA) mice model and healthy control (Ctrl) mice. DBA/1J male mice (age: 6-7 weeks) were selected and randomly divided into two groups, viz. a CIA- and a Ctrl group. The CIA mice were injected intraperitoneal (i.p.) with the joint cartilage component collagen type II (CII) and an adjuvant injection of lipopolysaccharide (LPS). Oxylipin metabolites were extracted from plasma for each individual sample using solid phase extraction (SPE) and were detected with high performance liquid chromatography/tandem mass spectrometry (HPLC-ESI-MS/MS), using dynamic multiple reaction monitoring (dMRM). Both univariate and multivariate statistical analysis was applied. The results in univariate student's t-test revealed 10 significantly up- or down-regulated oxylipins in CIA mice, which were supplemented by another 6 additional oxylipins, contributing to group clustering upon multivariate analysis. The dysregulation of these oxylipins revealed the presence of ROS-generated oxylipins and an increase of inflammation in CIA mice. The results also suggested that the Collagen-induced arthritis might associate with dysregulation of apoptosis, possibly inhibited by activated NF- κ B because of insufficient PPAR-γ ligands.
Project description:Fibroblast-like synoviocytes (FLS) were isolated from the inflamed joints of mice with collagen-induced arthritis (CIA) or the joints of naive littermates to characterise gene expression changes in response to chronic inflammation. Cells were isolated at two times of day (zeitgeber time, ZT4 and ZT16) to characterise diurnal variation in inflammatory symptoms and responses. FLS cells were isolated from joint digests based on Podoplanin expression prior to RNA extraction and library preparation for sequencing.
Project description:The destruction of bone and cartilage results in a loss of joint functionality, critically impairing the quality of life in arthritis patients. Synovial fibroblasts (SFs) critically contribute to the pathogenesis of rheumatoid arthritis (RA) by acquiring either a pro-inflammatory or tissue-destructive phenotype. To explore the molecular mechanisms underlying the pathogenic fibroblast phenotype in arthritis, we performed single-cell RNA sequencing (scRNA-seq) on the synovial cells which were isolated from collagen-induced arthritis (CIA) mice.
Project description:The molecular basis to autoimmune arthritis is unclear. Collagen Induced Arthritis (CIA) in mice, is a model that has many features that resemble Rheumatoid Arthritis (RA), although it does not perfectly duplicate RA. The study of CIA has provided insight into relevant pathogenesis and has aided in the identification of potential therapeutic targets. In this study we used Mouse Cytokine Expression Arrays to examine gene expression levels in joints at early, peak and decline stages during disease in DBA/1 mice. The aim of the study was to identify candidate molecules that may be involved in the development and progression of collagen-induced arthritis (CIA). Keywords: Disease State Analysis
Project description:This study identifies molecular changes in hematopoietic stem cells (HSC) isolated from mice with chronic autoimmune arthritis induced using the collagen-induced arthritis (CIA) model.
Project description:To determine te lncRNA expression profile in collagen-induced arthritis rats and normal rats, we uesed lncRNA microArray analysis form Arraystar to examine the expression of lncRNAs in CIA and normal rats' synovial tissues.
