The apoptosis of Tca8113 cells were induced by VM-26 in a time-dependent manner according to the results of Annexin-V/PI assay. 5.0 mg/l of VM-26 demonstrated more apoptosis-inducing effect on Tca8113 cells than 0.15 mg/l did. The results were expressed as mean ± SD of three independent experiments.
