MiR-203 Participates in Human Placental Angiogenesis by Inhibiting VEGFA and VEGFR2 Expression:
2018
Angiogenesis during placentation is of great significance in maintaining normal pregnancy. However, the molecular mechanisms of this process are not clear. It has been reported that miR-203 plays a critical role in the development and progression of many tumors but not focused on the relationship between miR-203 and placental angiogenesis. The present study aims to illustrate the correlation between miR-203 and vascular endothelial growth factor (VEGFA)/vascular endothelial growth factor receptors 2 (VEGFR2) in human placenta and human umbilical vein endothelial cells (HUVECs) obtained from 40 samples. Samples of human placenta were collected based on gestation age, which was divided into early preterm (n = 10), late preterm (n = 12), and term (n = 18). In this work, we demonstrated that the expression of miR-203 decreased significantly in the placenta according to the gestation age, in contrast, the expression of VEGFA and VEGFR2 increased accordingly. In vitro experiments revealed that overexpression of...
