Pro-survival genes are up-regulated in alternatively activated macrophages. (A) List of top 10 DAVID functional annotation clusters for biological processes significantly altered by GW501516 or Il-4 treatment, compared to the vehicle control (see Supplementary Tables 4 and 5 for gene lists). Microarray analysis was conducted in Pparδ-overexpressing RAW 264.7 cells treated with GW501516 (0.1 μM) or rIl-4 (10 ng/ml) overnight. (B) Heat maps were shown for selected genes from the top 10 regulated pathways (Figure 1A) by GW501516 (Pparδ agonist, left) or Il-4 treatment (right) presented as fold change over vehicle control. (C) Validation of Ppar target genes identified through microarray using qPCR in WT, Mac-Pparδ−/− and Mac-Pparδ/γ−/− BMDMs treated with GW0742 (0.1 μM) overnight. (D) Validation of Il-4 regulated genes in WT and Stat6−/− BMDMs incubated with rIl-4 (10 ng/ml) overnight. Values were expressed as means ± SEM. #p < 0.05 between vehicle and GW0742 or rIl-4 treatment.
