However, the mechanisms underlying the development of PE are not fully understood. ETS Variant Transcription Factor 4 (ETV4) plays an important role in cell proliferation, migration, and invasion. In this study, we aimed to explore the potential function of ETV4 in placental trophoblast cells. We analyzed the expression and location of ETV4 in PE and uncomplicated placental tissues using RT-qPCR, Western blotting, immunohistochemistry, and immunofluorescence staining. The results showed that both the mRNA and protein levels of ETV4 were markedly decreased in PE placental tissues compared with placental tissues from women with uncomplicated pregnancies (P &lt; 0.05). Then, the effects of ETV4 on HTR-8\/SVneo and Bewo cell proliferation, migration, and invasion were evaluated by MTT, 5-ethynyl-2-deoxyuridine (EdU), wound healing, and Transwell assays, respectively. The results showed that ETV4 knockdown inhibited both HTR-8\/SVneo and Bewo cell proliferation, migration, and invasion (P &lt; 0.05). Conversely, overexpression of ETV4 promoted both HTR-8\/SVneo and Bewo cell proliferation, migration, and invasion (P &lt; 0.05). We then measured the expression of MMP-2 and MMP-9 in HTR8\/SVneo cells. We found that ETV4 knockdown decreased the mRNA and protein expression of MMP-2 and MMP-9, while ETV4 overexpression increased MMP-2 and MMP-9 mRNA and protein expression (P &lt; 0.05). In conclusion, ETV4 plays an essential role in the proliferation, invasion, and migration of trophoblast cells by regulating MMP-2 and MMP-9. Our findings provide novel insight into the mechanisms underlying the occurrence of PE.<\/jats:p>\n
