KQ induces caspase-3 activation in HeLa cells. HeLa cells were treated with KQ (6.25, 12.5 and 25 µg/ml) for 24 h at 37°C, and caspase-3 activity was determined. Results are presented as the mean ± standard deviation of three independent experiments. *P<0.05 vs. control. K, kaempferol 3-O-β-(2″-acetyl) galactopyranoside; Q, quercetin.
