Abstract:
Objective To investigate the ameliorative effect of ginsenoside Rf on endometriosis(EMS)and its mechanism.Methods In animal experiments,Wistar female rats were randomly divided into sham group(laparotomy without other treatment),model group(EMS construction),low dose group(1.0 mg·kg-1 ginsenoside Rf),middle dose group(2.0 mg·kg-1 ginsenoside Rf),high dose group(3.0 mg·kg-1 ginsenoside Rf),positive group(0.25 mg·kg-1 pregnrienone capsule).The volume of ectopic lesions and the number of painful twisting were detected;the apoptosis rate in tissues was detected by TdT mediated dUDP nick end labeling(Tunel)assay;the expression of related proteins in each group was detected by Western blot assay.Cell experiment:The isolated primary rat endometrial cells were randomly divided into control group(normal tissue isolation),EMS group(EMS cells),Rf group(20 μmol·L-1 ginsenoside Rf treated EMS cells),combined group(20 μmol·L-1 ginsenoside Rf and 50 μmol·L-1 autophagy inhibitor 3-MA treated EMS cells).Western blot assay was used to detect the expression of related proteins;flow cytometry was used to detect apoptosis.Results Animal experiment:The times of body twisting in sham group,model group,high dose group and positive group were 0,37.10±4.64,14.70±1.90 and 20.20±1.78,respectively;the ectopic lesion volumes were 0,(118.91±19.51),(50.11±9.69)and(37.64±3.56)mm,respectively;the apoptosis rates were(3.43±0.33)％,(3.22±0.27)％,(20.42±1.82)％and(22.92±2.67)％,respectively;Beclin 1 protein expression were 0.32±0.03,0.36±0.04,0.79±0.12,0.35±0.07,respectively;glutathione peroxidase 4(GPX4)protein expression were 1.10±0.07,0.94±0.11,0.53±0.03,0.96±0.16,respectively.The above indexes of the model group were compared with those of the sham group,and the above indexes of the high dose group were compared with those of the model group,and the differences were significant(all P＜0.05).Cell experiment:Beclin1 protein expression in control group,EMS group,Rf group and combined group were 0.22±0.05,0.31±0.03,0.52±0.07 and 0.19±0.03,respectively;GPX4 protein expression were 0.97±0.07,0.81±0.09,0.63±0.05 and 1.05±0.09,respectively;the apoptosis rates were(3.48±0.04)％,(3.42±0.23)％,(21.66±2.95)％and(12.51±1.15)％,respectively;the above indexes in Rf group were compared with those in EMS group,and the above indexes in combined group were compared with those in Rf group,and the differences were significant(all P＜0.05).Conclusion Ginsenoside Rf can improve endometrial lesion,pain sensitivity and apoptosis in EMS rats,which may be related to the regulation of autophagy dependent ferroptosis.
