To determine any effect on cell cycle or apoptosis, SiHa cells were treated with DMSO or 10 µM of compounds 478166, 478168, 44234, or 2 µM staurosporine for 48 hours. After 48 hours, cells were harvested, stained with propidium iodide, and DNA content was analyzed by flow cytometry. The percent of cells in G0/G1, G2/M, S, or apoptotic were determined by the areas under the curves represented by B, C, D, and E, respectively.
