Effect of DHC on cell cycle.

<p>A, HUVECs were starved for 24 h, and then were treated with or without DHC (3–10 µM) for 18 hr. After cells were labeled with propidium iodide, DNA content was analyzed by flow cytometry. B and C, cell population in G0/G1 and S/G2/M phase were quantified. Data represent the mean ± SEM from four independent experiments. * <i>P</i><0.05, ** <i>P</i><0.01 and *** <i>P</i><0.001 versus control.
