Effect of FAA on executioner caspases-3 activity in HepG2 cells. The cells were treated with IC25 = 42, IC50 = 26.67 and IC75 = 11.67 of FAA 24, 48 and 72 h treatment. Results are expressed as the mean optical density (405 nm) ± SD of three independent experiments. The symbol * indicates significant difference from control (p < 0.05)
