Effect of rosiglitazone and pioglitazone treatment on expression of PPAR target genes during adjuvant-induced arthritis. Animals were treated daily for 21 days with rosiglitazone (ROSI) 10 mg/kg or pioglitazone (PIO) 30 mg/kg by oral administration. Arthritic (adjuvant-induced arthritis (AIA)) and normal controls were given 0.5% carboxymethylcellulose alone. mRNA levels of adiponectin and peroxisome proliferator-activated receptor (PPAR)-γ normalized to RP29 in adipose tissue were assessed by RT-quantitative polymerase chain reaction. Data are expressed as means ± SEM for three representative samples per group (arthritis score close to the mean score of the group). #, P < 0.05 compared with AIA controls (ANOVA and Fisher's PLSD post-hoc test).
