PPAR, peroxisome proliferator-activated receptor; AIA, adjuvant-induced arthritis; ROSI 10, rosiglitazone 10 mg/kg/day; PIO 30, pioglitazone 30 mg/kg/day; VEGF, vascular endothelial growth factor; bFGF, basic fibroblast growth factor; MCP-1, monocyte chemotactic protein-1. Data are expressed as means ± SEM of mRNAs of the gene of interest over L27 mRNA (n = 3 representative samples per group).

*, P < 0.05 compared with normal controls; #, P < 0.05 compared with AIA controls (ANOVA and Fisher's PLSD test).
