Project description:Objective: Joint formation begins with the establishment of an interzone within the cartilaginous anlagen of the future skeleton and both Gdf5 and Erg are proposed as regulators of chondrocyte differentiation during and post interzone formation. The aim of this study was to examine the relationship between Gdf5 and Erg expression and downstream effects on chondrocyte gene expression. Design: Erg expression was identified in mouse knee joints at E13.5. Expression and microarray analyses were performed using micromass cultures of murine C3H10T1/2 mesenchymal cells undergoing induced chondrogenesis in the presence of absence of Gdf5 and Erg. Results: At E13.5, Erg expression was found to surround epiphyseal chondrocytes and span the interzone up to the intermediate zone. Erg splice forms were expressed in micromass cultures, and their expression profile was altered by the addition of recombinant Gdf5 depending on the stage of differentiation. Overexpression of Erg-010 resulted in a downregulation of Col2a1 and Col10a1. Microarray analysis following Erg-010 overexpression identified two potential downstream targets, Ube2b and Osr2, which were also differentially regulated by Gdf5. Conclusion: Erg regulation by Gdf5 in mesenchymal cells in vitro is dependent on the stage of chondrogenesis, and its expression in vivo demarcates chondrocytes that are not destined to be consumed by endochondral ossification. Functionally, Erg expression causes downregulation of Col2a1 and Col10a1 expression and this effect is potentially mediated by Osr2, which is a known regulator of chondrocyte differentiation. The identification of Ube2b as a putative downstream target of Erg-010 suggests that it may contribute to the regulation of the ubiquitination pathway and thereby BMP2 signaling, which is essential for normal knee joint development. RNA from overexpression experiments was extracted as described above. Total RNA quality was confirmed using a Bioanalyzer 2100 (Agilent). Labelled targets were generated from total RNA and hybridized to GeneChip Mouse Genome 430 2.0 arrays (Affymatrix) (Genomics Centre, University of Manchester). The raw fluorescence intensity values were normalized using a Robust Multi-array Average approach using dChip (V2005)

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. Keywords: disease severity analysis

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:The aim of this study was to better understand the resolution of inflammation and fibrosis in the soft tissue of the knee joint and the draining iliac lymph nodes (LNs) after surgery in a mouse tibial implant model. To do this, we collected the joint tissues from operated mice at 5 different timepoints (3, 7, 14, 21, and 35 days), plus joint tissue from the contralateral, non-operated limb at 35 days as a negative control. We also collected iliac LNs at days 7 and 14 post implantation surgery from the operated and contralateral sides; as controls we used LNs from non-operated mice. Transcriptomic analysis of the joint soft tissues revealed molecular pathways active during postoperative tissue repair.

Project description:Diseases of the knee joint such as osteoarthritis affect all joint elements. A human cell-derived ex vivo model capable of simulating intraarticular tissue crosstalk is desirable for studying etiologies/pathogenesis of joint diseases and testing potential therapeutics. Herein we generated a human mesenchymal stem cell-derived microphysiological joint-on-a-chip system (microJoint), in which engineered osteochondral, synovial, and adipose tissues were integrated into a microfluidics-enabled bioreactor. This novel design facilitated different tissues communicating while still maintaining their respective phenotypes. The microJoint exhibited physiologically relevant changes when exposed to interleukin-1β mediated inflammation, which were similar to observations in joint diseases in humans. The potential of the microJoint in predicting in vivo efficacy of drug treatment was confirmed by testing the “therapeutic effect” of the nonsteroidal anti-inflammatory drug, naproxen, as well as four other potential disease-modifying osteoarthritis drugs. The data demonstrate that the microJoint recapitulates complex tissue interactions, thus providing a robust model for the study of joint pathology and the development of novel therapeutic interventions.

Project description:Objectives : Joint pain causes a significant morbidity in osteoarthritis (OA). The synovium as an innervated joint structure might contribute to the peripheral pain in OA. Methods : We used a hypothesis-free next generation RNA sequencing to study protein coding and small non-coding transcriptomes in knee synovial tissues of OA patients (n=10) with high and low knee pain (evaluated by visual analogue scale) followed by Gene Ontology (GO) and pathway analyses and integration of mRNAs and small RNAs data sets. Results : We showed that 33 protein-coding genes and 35 small RNAs were differentially expressed in the knee synovium of patients with high compared to low intensity knee pain, with 30 mRNAs and 14 small RNAs being upregulated and 2 mRNAs and 21 small RNAs being downregulated. Top enriched genes, such as SDIM1 and CPE encode neuronal proteins that share molecular properties with neurotrophic factor BDNF and promote neuronal survival under cellular stress, and OTOF participates in calcium-dependent synaptic exocytosis and modulation of GABAergic activity. TrkB was enriched in several gene networks, suggesting its key role in pain-related transcriptional changes in OA joint. Downregulation of PTX3 in high pain group supports an argument that inflammation and pain are independent processes in symptomatic knee OA. MiR-146a-3p and miR150 appeared as the microRNA candidates in the pathogenesis of OA-related knee pain. Conclusions : Here we uncovered the molecular complexity of pain-related transcriptome changes in the synovium of knee joints in osteoarthritis. We identified new molecular candidates in OA pain setting a firm ground for future mechanistic studies and drug discovery in OA.
