TNF-α and IL-1β mRNA levels are reduced by PPARγ and RXR agonists. TNF-α (A) and IL-1β (B) mRNA levels in the colon of mice receiving vehicle only (Control), TNBS, rosiglitazone (Rosi at 20 mg/kg/d), LG101305 (LG at 20 mg/kg/d), or simultaneous administration of rosiglitazone and LG101305 (Rosi + LG both at 1 mg/kg/d) 2 d before the administration of TNBS. Animals were killed 2 d after TNBS administration. Results are expressed as mean ± SEM. mol, molecules. (A): (a) P < 0.001 in control vs. TNBS; (b) P = 0.001 in untreated TNBS colitis vs. mice receiving rosiglitazone; (c) P = 0.076 in untreated TNBS colitis vs. mice receiving LG101305; and (d) P = 0.05 in untreated TNBS colitis vs. mice receiving both rosiglitazone and LG101305. (B): (a) P < 0.001 in control vs. TNBS; (b) P = 0.001 in untreated TNBS colitis vs. mice receiving rosiglitazone; (c) P = 0.003 in untreated TNBS colitis vs. mice receiving LG101305; and (d) P = 0.003 in untreated TNBS colitis vs. mice receiving both rosiglitazone and LG101305.
