Effect of native etoposide and NP treatments on cell cycle distribution in Y-79 cells. Cell cycle distribution was determined by analysing 10,000 ungated cells using FACScan flow cytometer. Content of DNA is represented on the x-axis; number of cells counted is represented on the y-axis (n ¼ 3). a Cells incubated for 48 h. b Cells incubated for 120 h
