Methods: Human ovarian cancer HO-8910 cells were cultured in vitro. Inhibi- tory effect of ONY on the viability of HO-8910 cells was evaluated by the MTT assay. Apoptosis of HO-8910 cells treated with different concentrations of ONY for 48 h was detected by FCM. Expression of proteins related to apoptosis was analyzed by Western blot. Results: ONY significantly inhibited the viability of human ovarian cancer HO-8910 cells in a dose-dependent and time-dependent manner, and the ICso was 10.48 pg/mL for 48 h. The cells treated with ONY showed typical morphological change of apoptosis and increased cells of sub-G1 population by FCM in a dose-dependent. Western blot showed that ex- pression of Bax, cytochrome C, caspase-9 and caspase-3 proteins were upregulated and protein level of Bcl-2 was depressed after treatment with ONY in a concentration dependent. Conclusion: Apoptosis of ovarian cancer HO-8910 cells was induced by ONY through mitochondrial apoptosis pathway in vitro.展开更多
