OBJECTIVE: To investigate the expression of micro ribonucleic acid miR-518b and its regulatory role in the pathogenesis of placenta accreta.

PATIENTS AND METHODS: A total of 50 parturient women in the Obstetric Department were collected and divided into observation group (placenta accreta, n=23) and control group (normal placenta, n=27). After the placental tissues were removed via surgery, the expressions of osteopontin (OPN) and vascular endothelial growth factor (VEGF) were detected using the immunohistochemical method. The relative expression levels of OPN and VEGF proteins were detected via Western blotting, and the relative expression levels of OPN messenger RNA (mRNA), VEGF mRNA and miR-518b were detected via quantitative polymerase chain reaction (qPCR). Moreover, the correlations of miR-518b with OPN mRNA and VEGF mRNA were studied via Pearson correlation analysis.

RESULTS: Compared with those in control group, the expressions of OPN and VEGF proteins in observation group were significantly increased, while the levels of OPN mRNA, VEGF mRNA and miR-518b in observation group were also significantly elevated (p<0.05). There were positive correlations between miR-518b and levels of OPN, VEGF mRNA.

CONCLUSIONS: The high expression of miR-518b may lead to the development of placenta accreta through upregulating the transcription and protein expression of downstream VEGF and OPN, providing insights for the future therapy against the pathogenesis of placenta accreta.
