- Abstract: Objective To investigate the effect of icariin on apoptosis of ovarian granulosa cells in rats with polycystic ovarian syndrome(PCOS)by regulating stromal cell-derived factor-1(SDF-1)/CXC chemokine receptor-4(CXCR4)signal axis.Methods Granular cells successfully isolated from ovarian tissue of rats in the PCOS model group were grouped into the PCOS group,the low-dose icariin group,the medium-dose icariin group,the high-dose icariin group,the Rr-SDF-1 group and the high-dose icariin+Rr-SDF-1 group.Granular cells successfully isolated from ovarian tissue of rats in the normal control group were taken as the control group.Enzyme-linked immunosorbent assay(ELISA)was applied to detect levels of follicle-stimulating hormone(FSH),testosterone(T)and luteinizing hormone(LH)in supernatant of ovarian granulosa cells.CCK-8 method and EdU staining were applied to detect granulosa cell proliferation.Flow cytometry was applied to detect granulosa cell apoptosis.Western blot assay was applied to detect the expression of Bcl-2 associated X(Bax),Cleaved aspartate-specific cysteine protease-3(Cleaved Caspase-3),SDF-1,and CXCR4 proteins in granulosa cells.Results Compared with the control group,the FSH level,OD450 value and EdU positive cell rate were decreased in the PCOS group,and T and LH levels,apoptosis rate,Bax,Cleaved Caspase-3,SDF-1 and CXCR4 protein expression increased(P＜0.05).Compared with PCOS group,the FSH level,OD450 value and EdU positive cell rate were increased sequentially in the icariin low,medium and high dose groups,T and LH levels,apoptosis rate,Bax,Cleaved Caspase-3,SDF-1 and CXCR4 protein expression levels were decreased sequentially,and change trends of corresponding indicators were opposite to the above in the Rr-SDF-1 group(P＜0.05).Compared with the high-dose icariin group,FSH level,OD450 value and EdU positive cell rate were decreased in the high-dose icariin+Rr-SDF-1 group,and T and LH levels,apoptosis rate,Bax,Cleaved Caspase-3,SDF-1 and CXCR4 protein expression levels were increased(P＜0.05).Conclusion Icariin may inhibit the apoptosis of ovarian granulosa cells in PCOS rats by inhibiting the SDF-1/CXCR4 signaling pathway.
