Figure 8From: Topoisomerase II trapping agent teniposide induces apoptosis and G2/M or S phase arrest of oral squamous cell carcinomaThe cells were harvested and analyzed with propidium iodide staining to assess cell cycle distribution by FACS analysis and the results were expressed as mean ± SD of three independent experiments. Overlay of cell cycle distributions of Tca8113 cells exposed to 5.0 mg/l of VM-26. The line in yellow, green, red, light blue and brown indicated the cell cycle distributions of control cells, and of cells treated with VM-26 for 12 hours, 24 hours, 36 hours and 48 hours, respectively. The cell cycle of Tca8113 cells were obviously arrested at S phase as time lapsed.Back to article page
