Effect of EX527 and (or) gemcitabine (GEM) on cell cycle distribution in pancreatic cancer cells. Cycle phase distributions of PANC-1 (a) and ASPC-1 (b) cells were analyzed by flow cytometry after staining with propidium iodide. Percentage of cells in each phase of the cell cycle (G0/G1, G2/M and S-phase) is indicated. The experiments were repeated twice with similar results.
