Effect of saikosaponin-d and radiation on the cell cycle distribution of SMMC-7721 human hepatocellular carcinoma cells under oxia and hypoxia. A. Changes in cell cycle distribution under oxia; B. changes in cell cycle distribution under hypoxia; C. Statistical analysis showing the changes in cell cycle progression before and after intervention under oxia; D. Statistical analysis showing the changes in cell cycle progression before and after intervention under hypoxia. SSd: saikosaponin-d; IR: radiation. *p < 0.05, ** p < 0.01 vs. control.
