From: Paris saponin VII suppressed the growth of human cervical cancer Hela cells
The effect of PS VII treatment on the apoptosis of Hela cells. (a) Annexin V analysis of Hela cells treated with PS VII at the concentrations of 0.8, 1.6, and 2.4 μM for 24 h. PS VII treatment increased the percentages of annexin V+/PI - (right lower quadrant) and annexin V+/PI + (right upper quadrant) cells. (b) Effect of PS VII on the caspase-3 activity of Hela cells. Data were the mean ± SD of three separate experiments. **P < 0.01 vs. control.
