RNA-seq of synovial membranes from a preclinical model of post-traumatic knee osteoarthritis to evaluate the effects of corticosteroid treatment

Project description:Yorkshire pigs received untreated unilateral ACL transection through a medial arthrotomy (INJ, n=6), transection with immediate injection of 20mg triamcinolone acetonide (TRI, n=6) or no surgery (CON, n=6). Synovial membranes were harvested two weeks after the injury in the lateral knee joint compartment. The whole biopsy was homogenised for RNA extraction. The objective of the experiment was to test if intraarticular corticosteroid injection mitigates injury-induced synovitis and collagen degradation after anterior cruciate ligament transection and to characterize the synovial response using the described perturbations in combination with a functional genomics approach.

Gene expression in synovial membranes from patients with early and end-stage osteoarthritis

Project description:Osteoarthritis is characterized by degeneration of cartilage and bone in the synovial joints. Recent findings suggest that inflammation may play a role in osteoarthritis, with synovitis being associated with the clinical symptoms of osteoarthritis. Furthermore, we have found that levels of inflammatory complement components are abnormally high in the synovial fluid of individuals with osteoarthritis. To determine whether synovial membranes could be a source of complement and other inflammatory molecules in osteoarthritic joints, we characterized the expression of genes in synovial membranes from patients with early-stage or end-stage osteoarthritis. Samples of synovial membrane were obtained from the suprapatellar pouch of patients with osteoarthritis who were treated at the Hospital for Special Surgery. Specifically, samples were from 10 patients with early-stage knee osteoarthritis who were undergoing arthroscopic procedures for degenerative meniscal tears (with documented cartilage degeneration but no full-thickness cartilage loss, Kellgren Lawrence score </=2), and from 9 patients with end-stage knee osteoarthritis ( diffuse full thickness cartilage erosion) who were undergoing total knee joint replacement. Raw data from microarray analysis of healthy synovial membranes, which were run on the same platform and array as our osteoarthritic samples, were downloaded from the NCBI Gene Expression Omnibus (accession number GSE12021) and used for comparison. The 19 new Samples of this Series were analyzed (RMA) together with 7 previously submitted healthy individual Samples (GSM175810, GSM175812, GSM176290, GSM176291, GSM176292, GSM176268, GSM176269). The complete RMA data are provided as a supplementary file on the Series record. The GSE12021 reanalyzed data are also provided as a supplementary file on the Series record. GSE32317_12genes.txt includes data from figure 1 of the paper.

Profiling the knee joints of mice with Type 1 diabetes mellitus

Project description:Type 1 diabetes mellitus (T1DM) affects 9.5% of the population. T1DM is characterized by severe insulin deficiency that causes hyperglycemia and leads to several systemic effects. T1DM has been suggested as a risk factor for articular cartilage damage and loss, which could expedite the development of osteoarthritis (OA). OA represents a major public health challenge by affecting 300 million people globally, yet very little is known about the correlation between T1DM and OA. In this study we aimed to understand the role of T1DM in OA by evaluating whether pre-existing T1DM exacerbates the development of knee post traumatic osteoarthritis (PTOA).

Expression data from fetal membranes

Project description:Genome wide expression profiling was used to identify signifnificantly changed genes in fetal membranes after GBS treatment Genome-wide expression profiles in GBS-inoculated human extraplacental membranes in vitro were used to identify transcriptomic pathways altered by GBS . Using bioinformatics analysis of these expression profiles we aimed to test our hypothesis that GBS activates pathways related to inflammation and premature birth in human extraplacental membranes.

KLF15 Cistromes Reveal a Hepatocyte Pathway Governing Plasma Corticosteroid Transport and Systemic Inflammation

Project description:Circulating corticosteroids orchestrate stress adaptation, including inhibition of inflammation. While pathways governing corticosteroid biosynthesis and intracellular signaling are understood, less is known about mechanisms controlling plasma corticosteroid transport. Here, we show hepatocyte KLF15 (Kruppel-like factor 15) controls plasma corticosteroid transport and inflammatory responses through direct transcriptional activation of Serpina6, which encodes corticosteroid binding globulin (CBG). Klf15-deficient mice have profoundly low CBG, reduced plasma corticosteroid binding capacity, and heightened mortality during inflammatory stress. These defects are completely rescued by reconstituting CBG, supporting that KLF15 works primarily through CBG to control plasma corticosterone homeostasis. To understand transcriptional mechanisms, we generated the first KLF15 cistromes using newly engineered Klf153xFLAG mice. Unexpectedly, liver KLF15 is predominantly promoter-enriched, including Serpina6, where it binds a palindromic GC-rich motif, opens chromatin, and transactivates genes with minimal associated gene repression. Overall, we provide new mechanistic insight into KLF15 function and identify a hepatocyte-intrinsic transcriptional module that potently regulates systemic corticosteroid transport and inflammation.

Gene expression changes associated with resistance to intravenous corticosteroid therapy in children with severe ulcerative colitis

Project description:Although corticosteroids remain a mainstay of therapy for UC, a meta-regression of cohort studies in acute severe ulcerative colitis (UC) showed that 29% of patients fail corticosteroid therapy and require escalation of medical management or colectomy. We aimed to determine whether genes expressed in whole blood early following initiation of intravenous corticosteroid treatment can be associated with response. 20 corticosteroid responsive (PUCAI < 35 by day 5) and 20 corticosteroid resistant patients (PUCAI ≥ 35 by day 5 and need for 2nd line medical therapy or colectomy by hospital discharge) were selected from a prospectively accrued cohort of patients hospitalized for intravenous corticosteroid treatment of severe UC. Total RNA was extracted from blood samples collected on day 3 of intravenous corticosteroid therapy. The eluted transcriptomes were quantified on Affymetrix Human Gene 1.0 ST arrays. The data was analysed by the local-pooled error method for discovery of differential gene expression and false discovery rate correction was applied to adjust for multiple comparisons. P-values less than 0.05 after correction were considered significant.

Comparative Transcriptomics of STR/ort, C57BL/6 and MRL/MpJ Knee Joints

Project description:Injuries to the anterior cruciate ligament (ACL) often result in post-traumatic osteoarthritis (PTOA). PTOA accounts for ~12% of all osteoarthritis (OA) cases, yet the mechanisms contributing to OA after joint injury are not well understood. To better understand the molecular mechanisms behind PTOA development following ACL injury, we profiled ACL injury-induced gene expression changes in knee joints of three mouse strains with varying susceptibility to PTOA: STR/ort (highly susceptible), C57BL/6 (moderately susceptible) and super-healer MRL/MpJ (not susceptible) and identified genes differentially expressed between these strains at 0-day [before injury], 1-day, 1-week, and 2-weeks post-injury. This study highlights many new potential therapeutic targets and OA biomarkers.
