Validation of microarray data for selected genes by real-time PCR. (A and B) Differentially expressed genes in PBMC from JIA patients who achieved remission using MTX alone or MTX + Et were compared to healthy controls in training cohort (A) and testing cohort (B). (C and D) Differentially expressed genes in granulocytes from JIA patients who achieved remission using MTX alone or MTX + Et were compared to healthy controls in training cohort (C) and testing cohort (D). ET, etanercept; JIA, juvenile idiopathic arthritis; MTX, methotrexate; PBMC, peripheral blood mononuclear cells.
