Author: L. Han, Y. Zhao, Q. Q. Luo, X. X. Liu, S. S. Lu, L. Zou


AIM: The aim of this study was to explain the effects of miRNA-145 in the pathogenesis of preeclampsia.
METHODS: Collecting the placental tissue of 40 severe preeclampsia patients and 20 normal pregnant women, and observation of the pathological findings by HE staining. Measuring the miR-145 by RT-PCR. EVCT were divided into NC group; MC group and miRNA group. The EVCT cells of MC and miRNA groups were simulated by hypoxia in vivo by CoCl2. Measuring the proliferation rate of different groups by MTT testing. The cells apoptosis rates were measured by flow cytometry; evaluating PI3K, Akt, mTOR and P53 gene and protein expression of three groups by RT-PCR and WB.
RESULTS: Compared to the normal pregnant placental tissue. The miR-145 expression of preeclampsia pregnant placental tissue was significantly decreased (p < 0.05).

In the cell experiments, the proliferation rate was significantly increased, and the cell apoptosis rate was significantly reduced in MC group compared to the MC group (p<0.05, respectively). Comparing with MC group, the PI3K, Akt and mTOR gene and protein expression of miRNA group were significantly up-regulated and the P53 expression was significantly down-regulated (p<0.05, respectively).
CONCLUSION: miR-145 might have effects to predict preeclampsia via PI3K/Akt/mTOR signalling pathways (Fig. 5, Ref. 30).
