1. Skin tumor size following ligand activation of PPARβ/δ and inhibition of COX2.
Skin tumor size following ligand activation of PPARβ/δ and inhibition of COX2. Wild-type (+/+) and Pparβ/δ-null (−/−) mice were treated with topical GW0742 (5 μmol/L), dietary nimesulide (400 mg/kg), or the combination of GW0742 and nimesulide during a 42-week, 2-stage bioassay (initiation with DMBA and promotion with TPA) as described in Materials and Methods. A, incidence of mice with different tumor sizes. These values represent the percentage of mice within a given group that exhibited skin tumors with the indicated size range. B, distribution of average tumor size for each treatment group. Mice within each treatment were used to calculate the percentage of tumors of that particular size range for each treatment group. *, significantly different from control wild-type, P ≤ 0.05.
