ABSTRACT
OBJECTIVE:
To study the effects of mifepristone on the expression of inflammatory factors in endometriosis (Ems)model rats.METHODS:
SD rats were randomly divided into normal group(normal saline),model group(normal saline), mifepristone low-dose,medium-dose and high-dose groups [0.65,1.30,2.60 mg/(kg·d)],with 10 rats in each group. Except for normal group,Ems model was induced in other groups,and they were given relevant medicine intragastrically for consecutive 4 weeks. The volume of the ectopic focus was compared before and after treatment. The serum contents of TNF-α,IL-6 and IL-8 were detected by ELISA method. The phosphorylation of NF-κB p65 and the expression of COX-2 and PGE2 were detected by West-ern blot. The expression of NF-κB p65 mRNA in ectopic focus was detected by RT-PCR.RESULTS:
Compared with normal group,the volume of the ectopic focus,the serum contents of TNF-α,IL-6 and IL-8,the expression of COX-2 and PGE2 protein, the phosphorylation of NF-κB p65 and the expression of NF-κB p65 mRNA in ectopic focus were increased in model group(P<0.01). Compared with model group,the volume of the ectopic focus,the serum contents of TNF-α,IL-6 and IL-8,the expression of COX-2 and PGE2 protein,the phosphorylation of NF-κB p65 and the expression of NF-κB p65 mRNA in ectopic focus were de-creased in mifepristone groups(P<0.01),in dose-dependent manner.CONCLUSIONS:
Mifepristone can reduce the volume of the Ems ectopic focus,via blocking NF-κB signaling pathway and reducing the expression of inflammatory factors.
