Results:Arsenic trioxide could inhibit the growth of 3AO?SKOV 3 and TYK effectively, depended on the action time and concentration of the medicine(P0.05). The growth inhibited rates of different types of the human ovarian cancer cells were equal, (P0.05). Within a certain range, 3AO cells apoptotic percentage induced by arsenic trioxide were enhanced in concentration- and time-dependent patterns(P0.05);3.0 μmol/L was the most appropriate concentration to induce apoptotosis; 3AO S phase cells were arrested in lower concentrations of arsenic trioxide at S phase, while higher concentrations induced apoptosis selectively in these cells; SKOV 3 cells after treated by arsenic trioxide showed morphological changes characteristic of apoptotic cells.Conclusions:Arsenic trioxide can inhibit the proliferation of human ovarian cancer cells by inducing S phase cells apoptosis, and it is concentration-dependent, time-dependent and cell cycle specificRead More
