Effects of RF-Id on cell cycle. U87-MG cells were treated for 72 h with IC:50 of RF-Id and subsequently were stained with propidium iodide for 1 h and analyzed by flow cytometry. For each sample, the percentage of cells in each phase of the cell cycle (G0 / G1-S-G2M) was calculated. The experiments were repeated three times giving always similar results. Bars, SDs. ** p ≤ 0.01
