Farrerol (FA) inhibits cell proliferation of SKOV3 cells through G2/M cell cycle arrest. (a) Crystal violet-stained cell images of SKOV3 cells after treatment with the indicated concentration of FA for 24 and 48 h. (b) The cell viability of SKOV3 and EA.hy926 on FA treatment cells was measured via an MTT assay. Data are means ± standard deviation from three independent experiments (*, p < 0.05). (c) SKOV3 cells were treated with FA (0, 40, 80, or 160 μM) for 24 or 48 h, harvested, and digested with RNase. Cellular DNA was stained with propidium iodide, and the cell cycle distribution was analyzed using flow cytometry. (d) Cell cycle distribution data.
