ABSTRACT
BACKGROUND:
Preeclampsia (PE) is a common hypertensive disorder of pregnancy. Recent studies have suggested that circular RNAs (circRNAs) play a pathological role in PE. Herein, this study aimed to investigate the action and mechanism of circ_0037078 in PE process.METHODS:
The quantitative real-time PCR (qRT-PCR) and Western blot were used to determine the expression levels of RNAs and genes. Cell proliferation, migration, invasion and angiogenesis were evaluated by using cell counting kit-8 (CCK-8), colony formation, transwell, and tube formation assays, respectively. The target relation between miR-576-5p and IL1RAP (Interleukin-1 receptor accessory protein) and circ_0037078 was predicted by bioinformatics analysis and verified by dual-luciferase reporter and RNA immunoprecipitation (RIP) assays.RESULTS:
Circ_0037078 expression was higher in placental tissues of patients with PE than that of normal control. Knockdown of circ_0037078 led to an enhancement of the proliferation, migration, invasion, and angiogenesis in trophoblast cells. Mechanistically, circ_0037078 acted as a sponge for miR-576-5p, thus elevating the expression of IL1RAP, which was targeted by IL1RAP. Further rescue experiments suggested that miR-576-5p inhibition reversed the effects of circ_0037078 knockdown on above behaviors of trophoblast cells. Moreover, miR-576-5p overexpression enhanced the proliferative, migratory, invasive, angiogenic phenotypes of trophoblast cells, which were attenuated by IL1RAP up-regulation.CONCLUSION:
Circ_0037078 knockdown promotes trophoblast cell proliferation, migration, invasion, and angiogenesis in vitro by miR-576-5p/IL1RAP axis, providing a novel insight into the etiology of PE.Palabras clave
