OBJECTIVE: To evaluate the effects of antiprogestins mifepristone and lilopristone on proliferation and expressions of nuclear factor-kappa B (NF-kappaB) of ectopic stromal cells in vitro.
METHODS: The ectopic stromal cells of ovary were cultured in vitro. Methyl thiazolyl tetrazolium method was used to evaluate proliferative activity of ectopic stromal cells. Cells were divided into five groups according to drug concentration: control group, group I and group II of mifepristone and of lilopristone. The expressions of NF-kappaB P65 and NF-kappaB P65 mRNA of ectopic stromal cells were determined by immunocytochemistry and in situ hybridization of cell slice.
RESULTS: Antiprogestins mifepristone and lilopristone were able to significantly suppress the proliferation of ectopic stromal cells in a time- and dose-dependent manner in vitro. The expressions of NF-kappaB P65 and NF-kappaB P65 mRNA of ectopic stromal cells in the control group were higher than that of group I and group II. Their expressions in mifepristone groups were higher than that of lilopristone groups.
CONCLUSIONS: Antiprogestin mifepristone and lilopristone could significantly suppress the proliferation of ectopic stromal cells in a time- and dose-dependent manner in vitro. The action mechanisms may be associated with the suppression of expression of NF-kappaB P65 mRNA and NF-kappaB P65.
