Effects of Bushen Shengjing Tiaohe Qixue Prescription in Regulating Wnt/β-catenin Signaling Pathway on Diminished Ovarian Reserve Rats
摘要
Abstract
Objective To investigate the effects of Bushen Shengjing Tiaohe Qixue Prescription on rats with diminished ovarian reserve(DOR)based on Wnt/β-catenin signaling pathway.Methods Totally 60 8-week-old SD female rats were randomly divided into control group,model group,estradiol valerate group and TCM low-,medium-and high-dosage groups,with 10 rats in each group.Except for the control group,the rats in the other groups were given a single intraperitoneal injection of cyclophosphamide 75 mg/kg to replicate the DOR rat model.From the next day of modeling,the corresponding drugs was administered for medication groups by gavage for 3 weeks.The general conditions of the rats were observed,ELISA was used to detect the contents of serum follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),anti-mullerian hormone(AMH)and inhibin B(INHB),HE staining was used to observe the morphologic changes in ovarian tissue,Western blot was used to detect GSK3β,β-catenin,CyclinD1 and c-MYC protein expressions in ovarian tissues,immunohistochemical staining was used to observe β-catenin expression in ovarian tissue,RT-qPCR was used to detect Wnt1,Wnt2,Wnt4,GSK3β,β-catenin,CyclinD1 and c-MYC mRNA expression in ovarian tissue,transmission electron microscopy was used to observe ultrapathologic structure of ovarian granulosa cells.Results Compared with the control group,the rats in the model group had reduced intake of food and water,slow or even reduced body mass gain,and disturbed estrous cycle,the serum contents of FSH and LH increased(P<0.01),the contents of E2,AMH and INHB decreased(P<0.01);the number of follicles of all levels in ovarian tissue was reduced,and there was increased number of atretic follicles with disturbed arrangement of the granulosa cells;the expression of GSK3β protein in ovarian tissue increased(P<0.01),the expression of β-catenin,CyclinD1 and c-MYC protein decreased(P<0.05,P<0.01),and β-catenin positive expression decreased(P<0.01),the expression of Wnt1,Wnt2,Wnt4,β-catenin,CyclinD1 and c-MYC mRNA in ovarian tissue decreased(P<0.01),GSK3β mRNA expression was increased(P<0,01);organelles such as mitochondria and nuclei of ovarian granulosa cells were highly swollen and partially lysed.Compared with the model group,the rats in the administered group all had different degrees of body mass increase,partial restoration of the motility cycle,serum FSH and LH contents decreased,and serum E2,AMH and INHB contents increased(P<0.01,P<0.05);the number of follicles at all levels in ovarian tissue increased to varying degrees,and the atretic follicles were reduced;the expression of GSK3β protein in ovarian tissue decreased,β-catenin,CyclinD1 and c-MYC protein expressions increased,β-catenin positive expression increased,the expression of Wnt1,Wnt2,Wnt4,β-catenin,CyclinD1 and c-MYC mRNA in ovarian tissue increased,and GSK3β mRNA expression decreased,with statistical significance in estradiol valerate group and TCM high-dosage group(P<0.05,P<0.01);mitochondria,endoplasmic reticulum and other organelles of ovarian granulosa cells were mildly to moderately swollen.Conclusion Bushen Shengjing Tiaohe Qixue Prescription can improve ovarian function and regulate serum sex hormone levels in DOR model rats,and its mechanism might be related to the activation of Wnt/β-catenin signaling pathway.关键词
