SW480, HCT-116, and HT-29 cells were treated for 5 hours with varying concentrations of tocopherol or the PPAR γ ligand, troglitazone (positive control). The percent of dead cells for SW480 cells (A), HCT-116 cells (B) or HT-29(C) was measured using the Live-Dead assay (Molecular Probes, CA). (Data are representative of three independent trials performed in triplicate. *p < 0.05 vs. vehicle at corresponding concentration.)
