Figure 4From: Apigenin promotes apoptosis, inhibits invasion and induces cell cycle arrest of T24 human bladder cancer cellsCell cycle analysis of T24 bladder cancer cells treated with apigenin. (A)Cells were treated with different concentrations of apigenin for 24 h and then stained with propidium iodide. The DNA content was analyzed by flow cytometry. G1, S, and G2/M indicate cell cycle phase. (B) It shows an obvious G2/M phase arrest with a concomitant decrease of cell number in G1 phase of the cell cycle. The percent of G2/M phase was quantified from three independent experiments. * P < 0.05, ** P < 0.01 versus untreated control.Back to article page
