Rosiglitazone enhances fluorouracil-induced apoptosis of HT-29 cells by activating peroxisome proliferator-activated receptor γ

Figure 2 Apoptosis of HT-29 cells induced by AO/EB staining (A) and flow cytometrical analysis (B). HT-29 cells were treated with rosigliatzone and/or 5-Fu at the indicated concentration for 72 h, then harvested and stained with AO/EB. Results are representative of three experiments.
