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 therapyhttp://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-23687humanhttp://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-23687/samples/
