Figure 3From: Osthole induces G2/M arrest and apoptosis in lung cancer A549 cells by modulating PI3K/Akt pathwayCell cycle distribution analysis by DNA flow cytometry. (A) A549 cells were treated with (0, 50, 100 and 150 μM) Osthole for 48 h. Then the cells were harvested and treated with RNase, stained with PI. The cell cycle distribution was analyzed by flow cytometry. (B) The percentage of cells in G2/M phase in histograms. *p < 0.01, **p < 0.001 versus control group.Back to article page
