Top – DNA content analysis. The bars represent the ratio of cells in G1:G2M phase of the cell cycle after 12 hours of treatment with drug (RA+ = ATRA 10 μM. RA++ = ATRA 30 μM, FN+ = Fenofibrate 30 μM, FN++ = Fenofibrate 100 μM). Bottom – Apoptosis by FACS analysis using Annexin-FITC staining. Cells were treated for 3 hours. FN = fenofibrate, RG = rosiglitazone, St = staurosporine, a potent apoptogen.
