Gene expression in juvenile spondyloarthritis

ABSTRACT: Association of juvenile spondyloarthritis (jSpA) with the HLA-B27 genotype is well established, but there is little knowledge of other genetic factors with a role in disease development. The aim of the present study was to identify and confirm gene signatures and novel biomarkers in various cohorts of untreated and treated patients diagnosed with jSpA and other forms of juvenile idiopathic arthritis (JIA). DNA microarray gene expression was performed in 11 patients with jSpA and in four healthy controls, along with bioinformatics analysis of retrieved data (DAVID, GSEA, IPA).

Gene expression in juvenile spondyloarthritis

Project description:Association of juvenile spondyloarthritis (jSpA) with the HLA-B27 genotype is well established, but there is little knowledge of other genetic factors with a role in disease development. The aim of the present study was to identify and confirm gene signatures and novel biomarkers in various cohorts of untreated and treated patients diagnosed with jSpA and other forms of juvenile idiopathic arthritis (JIA). DNA microarray gene expression was performed in 11 patients with jSpA and in four healthy controls, along with bioinformatics analysis of retrieved data (DAVID, GSEA, IPA). Total RNA was isolated from whole blood of 45 children with known HLA genotype and diagnosis of jSpA according to ILAR criteria, 11 children with oligo- and polyarticular forms of JIA, as well as 12 age and sex matched control participants without diagnosis of chronic inflammatory disease. Of those 11 patient and 4 controls were utilized in the microarrays experiments, while the rest were used in the follow-up qPCR analyses

Remission in Polyarticular Juvenile Idiopathic Arthritis

Project description:Identify biomarkers to predict response to therapy in polyarticular juvenile idiopathic arthritis (JIA) using gene expression microarrays. 42 samples from 13 controls, 14 active patients, 9 patients in clinical remission with medication (CRM), and 6 patients in clinical remission without medication (CR). All patients had polyarticular JIA.

Transcription profiling of peripheral blood samples from juvenile idiopathic arthritis (JIA) patients pre and post methotrexate therapy. Expression data from SPARKS CHARMS JIA cohort

Project description:Gene expression on peripheral blood mononuclear cells (PBMC) from SPARKS CHARMS juvenile idiopathic arthritis (JIA) cohort pre and post methotrexate therapy. This is the first study to our knowledge, to evaluate gene expression profiles in children with JIA before and after MTX, and to analyze genetic variation in differentially expressed genes. We have identified a gene, which may contribute to genetic variability in MTX response in JIA. PBMC were isolated from blood samples taken from 11 patients with JIA pre methotrexate therapy and at 6 months into therapy

Common Immunologic Pathways Between Oligoarticular and Polyarticular Juvenile Idiopathic Arthritis

Project description:The polyarticular and oligoarticular forms of juvenile idiopathic arthritis are classified as distinct entities. At the same time, many children who present with an oligoarticular phenotype eventually evolve to a polyarticular disease pattern, suggesting that the phenotypes might share with overlapping molecular mechanisms. Using gene expression microarrays, we found that 14 genes in neutrophils and 55 genes in PBMC shows common patterns of differential expression when children with active oligoarticular and polyarticular JIA were compared with healthy controls. These results demonstrate that there are commonalities between oligoarticular and polyarticular JIA that suggest overlapping immune mechanisms. Total RNA was extracted from isolated PBMC and neutrophils from 14 patients with polyarticular JIA and 8 patients with pauciarticular JIA. Total RNA was extracted from neutrophils from 13 healthy controls and from PBMC from 15 healthy controls. Insufficient RNA for microarrays was obtained from neutrophils from two of the healthy controls.

Gene Expression Profiles Distinguish Children with Inactive Polyarticular Juvenile Idiopathic Arthritis (JIA) with a Predilection to Flare

Project description:Gene expression profiles were obtained from 17 children with rheumatoid factor negative (RF-) polyarticular juvenile idiopathic arthritis (JIA). The disease was inactive in all patients at visit 1. Thee disease remained inactive at visit 2 for 9 patients, while the other 8 patients were experiencing a disease flare at visit 2. The goal of the study was to better understand the underlying molecular biology of flares in JIA Total RNA was obtained from PBMC at two different times in the course of disease

Modeling Transcriptional Rewiring in Neutrophils through the Course of Treated Juvenile Idiopathic Arthritis

Project description:Neutrophils in children with the polyarticular form of juvenile idiopathic arthritis (JIA) display abnormal transcriptional patterns linked to fundamental metabolic derangements. These abnormalities include re-ordering of miRNA-RNA expression networks. In this study, we sought to determine the effects of therapy on miRNA-RNA networks in polyarticular JIA. We studied children with active JIA disease on therapy (ADM), children with inactive disease also on therapy (ID), and children with clinical remission on medication (CRM) using exon and miRNA microarrays and compared results to findings from healthy control (HC) children. We found substantial re-ordering of miRNA-RNA networks after the initiation of therapy. Each disease state was associated with a distinct transcriptional profile.
