Abstract:
Objective:to investigate the expression of integrin αvβ3 and osteopontin(OPN)in decidual tissues in missed abortion women with polycystic ovarian syndrome(PCOS).Methods:PCOS women with missed abor-tion(PCOS missed abortion group),non-PCOS with missed abortion(non-PCOS missed abortion group)and women with normal early pregnancy induced abortion(normal control group)who were admitted to the First Affili-ated Hospital of Xi'an Jiaotong University from February 2018 to December 2022 were selected as participants,and 20 subjects in each group.The expressions of integrin αvβ3 and OPN in decidual tissues among the three groups were detected.Correlation analysis was conducted between the expression levels of integrin αvβ3 and OPN in PCOS patients with missed abortion.Results:Integrin αvβ3 and OPN were mainly expressed in the epi-thelial cells of the uterus,as well as in decidual cells.There were significant differences in the positive rates and IHC scores of integrin αvβ3 and OPN in decidual tissues among the three groups(P<0.05).The positive rates and IHC scores in PCOS missed abortion group were significantly lower compared with non-PCOS missed abor-tion group and normal control group,and the difference was statistically significant(P<0.05),but there was no significant difference between non-PCOS missed abortion group and normal control group(P>0.05).The integrin αvβ3 and OPN in decidual tissues were mainly co-located in uterine epithelial cells.There were significant differ-ences in immunofluorescence intensity of integrin αvβ3 and OPN among the three groups(P<0.05).The missed abortion group of PCOS was significantly lower than that of non-PCOS missed abortion group and normal control group,and the difference was statistically significant(P<0.01).No significant difference was found between non-PCOS missed abortion group and normal control group(P>0.05).There were significant differences in the protein expression levels and mRNA expression levels of integrin αvβ3 and OPN in decidual tissue among the three groups(P<0.05).PCOS missed abortion group was significantly lower than non-PCOS missed abortion group and normal control group,and the difference was statistically significant(P<0.01).There was no significant difference between non-PCOS missed abortion group and normal control group(P>0.05).The results of Pearson correlation analysis showed that the protein and mRNA expression levels of integrin αvβ3 and OPN in decidual tis-sue of PCOS patients with missed abortion were significantly positively correlated(r>0,P<0.01).Conclusions:The integrin αvβ3 and OPN were expressed in both epithelial cells of the uterus and decidual cells in early preg-nancy.The expressions of them were significantly decreased in decidual tissues of PCOS patients with missed a-bortion,which might be related to reduced endometrial receptivity.The role of integrin αvβ3 and OPN in the occur-rence of missed abortion needs further study.
