Ubidecarenone induces G2/M cell-cycle arrest of glioblastoma but not non-cancerous cell lines. (A) Cell cycle analysis and quantification of human U251 glioma cells treated with 0, 75, 115, 230, 345, or 460 µM ubidecarenone. The percentage of cells in each phase (G0/1, S or G2 + M) is estimated from the frequency histograms. The percentage of cells in G2 + M phase is highlighted. (B) Quantification of human U251 glioma, rat C6 glioma, HA, or mouse NIH3T3 fibroblast cells in each cell phase. All data presented as mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 compared to control (no drug exposure) at the same cell cycle phase.
