ABSTRACT
Objective To investigate the effect of mifepristone on the activity of proliferation and the apoptosis, the expression of estrogen receptor (ER),progesterone receptor (PR) protein and morphology changes of human ovarian carcinoma cell line 3AO and SKOV3 in vitro. Methods The proliferative activity of 3AO and SKOV3, which were cultured in vitro, was measured by tetrazolium-based colorimetric assay (MTT assay). Flow cytormetry (FCM) was used to measure the expressive rate of ER, PR , p53 protein, bcl-2 protein, cell apoptotic rate and cell proliferative cycle of 3AO cells, which were cultured with different concentration and duration of mifepristone. The morphologic and ultrastructure changes of apoptotic 3AO cells was observed by the light and electron microscopy. Results Mifepristone inhibited significantly the proliferation of 3AO cells in dose-time dependent manner in vitro. The inhibitory rate of 3AO cells growth, which were cultured with different concentration of mifepristone( 5,10,20,40,80 ?mol/L) and duration (24,48,72 h) was from 1.7% to 75.0%(P0.05). 3AO cells apoptosis activity appeared the positive correlation with the dose of mifepristone and cultured duration (P
