a and b TAX treatment on HCT116 and HT29 cells resulted in accumulation of cells at the G2-phase. After 24 h incubation of TAX treated cells and staining with propidium iodide, DNA content was analyzed by flow cytometry. Percentage of cell population in G2-phase of the cell cycle is shown. c, d and e TAX treatment on HCT116 and HT29 cells resulted in growth inhibition and apoptosis, after 24 h incubation of TAX treated cells and staining with propidium iodide, Cells were analyzed by flow cytometry. Percentage of apoptotic cells is shown. Experiments were performed in triplicate
