Summary

The abnormal expression of lncRNAs and miRNAs has been found in the placentas of patients with preeclampsia (PE). Therefore, we determined the role of lncRNA FOXD2-AS1/miR-3127 in trophoblast cells. The expression of lncRNA FOXD2-AS1 was detected by qRT-PCR. The proliferation, migration and invasion ability of trophoblast cells were evaluated using CCK-8, wound healing and transwell assays. The target gene of lncRNA FOXD2-AS1 was determined by StarBase and luciferase reporter assays. Western blotting was used to analyze the expression of matrix metalloproteinase 2 (MMP2) and matrix metalloproteinase 9 (MMP9). The results showed that FOXD2-AS1 affected trophoblast cell viability in vitro, while the expression of miR-3127 was decreased. FOXD2-AS1 silencing decreased the promotion effects on trophoblast cell induced by miR-3127 inhibition. In addition, FOXD2-AS1 and miR-3127 presented the same effect on MMP2 and MMP9 levels. lncRNA FOXD2-AS1 modulated trophoblast cell proliferation, invasion and migration through downregulating miR-3127 expression. Therefore, lncRNA FOXD2-AS1 could act as a latent therapeutic marker in preeclampsia.
