5 or ��?1.5, as previously described (15). The Ingenuity Pathways Analysis application (IPA) was used to map the differentially expressed transcripts and proteins on to known pathways. Next, immunological pathways that were statistically enriched for either differentially expressed transcripts or proteins were selected as previously described (18). Extracellular proteins and genes in different pathways, which had high expression levels before or after treatment, were selected for ELISA analysis in nasal fluids from http://www.selleckchem.com/products/LY294002.html 23 Italian patients with IAR before and after treatment with GC. Albumin (ALB) was analyzed with an ELISA kit from Bethyl Laboratories (Montgomery, TX, USA). Apoliprotein H (apoH) was analyzed with an ELISA kit from United States Biological (Swampscott, MA, USA). Chemokine (C-C motif) ligand 2 (CCL2), chemokine (C-X-C motif) ligand 6 (CXCL6), macrophage colony-stimulating factor 1 (M-CSF) and tumor http://www.selleckchem.com/products/CHIR-99021.html necrosis factor ligand superfamily member 10 (TNFSF10) were analyzed with ELISA kits from R&D Systems Inc (Minneapolis, MN, USA). Secretoglobin, family 1A, member 1 (CC16) was analyzed with an ELISA kit from Bio Vender Laboratory Medicine (Brno, Czech Republic). Eosinophil cationic protein was analyzed with an ELISA kit from IG Instrumenten-Gesellschaft AG (Z��rich, Switzerland). Macrophage migration inhibitory factor (MIF) was analyzed with an ELISA kit from RayBiotech (Norcross, GA, USA). Vascular endothelial growth factor B (VEGFB) was analyzed with an ELISA kit from Gentaur (Brussels, Belgium). All experiments were performed according to the manufacturer��s protocol. Data were expressed as the mean?��?SEM. Differences between two paired experimental groups were analyzed by paired Student��s t-test. A P-value http://www.selleck.cn/products/wortmannin.html with IAR during the pollen season, before and after GC treatment, were analyzed with gene expression microarrays. This led to the identification of 25 up-regulated genes and 68 down-regulated genes (Table?S1). Pathway analysis of the differentially expressed genes revealed that no known immune response pathway was significantly enriched for those genes. We therefore selected the extracellular protein that encoded by the most differentially expressed gene for ELISA analysis in the validation material, namely CXCL6. To identify putatively GC-affected pathways, gene expression microarray data from nasal polyps from patients with IAR outside of season before and after treatment with GC were analyzed (12). This resulted in the identification of pathways as well as a selection of novel protein markers for analysis in the independent material. Those markers are listed in parentheses following each pathway: Acute phase response signaling (albumin and apoH), chemokine signaling, glucocorticoid receptor signaling (CC16 and CCL2), IL8 signaling and T?helper cell differentiation signaling (Table?1, see online supplement Table?S2 for complete list).
