Fig. 4From: Whole blood expression profiling from the TREAT trial: insights for the pathogenesis of polyarticular juvenile idiopathic arthritisMechanistic network derived from differential gene expression analysis of upstream regulators of differentially expressed genes using IPA and comparing untreated to healthy controls. Nodes in orange reflect predicted activation, while those in blue are predicted to be inhibited based on the patterns of differential gene expression. Upstream regulators CXCL8 (a) and CSF3 (b) show an activation patternBack to article page
