Many circular RNAs (circRNAs) have been confirmed to participate in the regulation of trophoblast cell function to mediate PE progression. However, whether circ_0077109 is involved in PE progression through regulating trophoblast cell function remains unclear.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Quantitative real\u2010time PCR was utilized for measuring the expression of circ_0077109, microRNA (miR)\u2010139\u20105p and homeobox D10 (HOXD10). Trophoblast cell proliferation, apoptosis, invasion, and angiogenesis was assessed cell counting kit 8 assay, EdU assay, flow cytometry, transwell assay and tube formation assay. In addition, western blot analysis was used to determine protein expression. The interaction between miR\u2010139\u20105p and circ_0077109 or HOXD10 was verified by dual\u2010luciferase reporter assay and RIP assay.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Our results pointed out that circ_0077109 was a circRNA with upregulated expression in PE patients. Overexpression of circ_0077109 suppressed trophoblast cell proliferation, invasion, and angiogenesis, while increased apoptosis. MiR\u2010139\u20105p was found to be sponged by circ_0077109, and its mimic reversed the suppressive effect of circ_0077109 on trophoblast cell function. HOXD10 was a target of miR\u2010139\u20105p, and its overexpression inhibited trophoblast cell proliferation, invasion, and angiogenesis. MiR\u2010139\u20105p inhibitor could repress trophoblast cell function, while this effect could be reversed by HOXD10 knockdown.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In summary, we confirmed that circ_0077109 inhibited trophoblast cell function through the regulation of miR\u2010139\u20105p\/HOXD10 axis, which might be a potential target for PE
