BACKGROUND: Pre-eclampsia (PE) is characterized by the onset of hypertension and proteinuria during pregnancy. Here, we aimed to explore the functions of nuclear receptor-interacting protein 1 (NRIP1) in PE mice and human placental JEG-3 cells. We evaluated its effects on JEG-3 cell proliferation, apoptosis, invasion, and inflammatory response and regulation of Wnt/β-catenin pathway.
METHODS: NRIP1 levels in human serum and placental tissues, JEG-3 cells, and mouse models were assessed via quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blotting. JEG-3 cell growth, apoptosis, migration, and invasion were evaluated via 5-ethynyl-2'-deoxyuridine, flow cytometry, and transwell assays. Levels of the inflammatory factors, matrix metalloproteinase (MMP)-2, tumor necrosis factor (TNF)-α, and interleukin (IL)-6, were determined via enzyme-linked immunosorbent assay. Wnt/β-catenin pathway was assessed via western blotting and qRT-PCR. Systolic blood pressure and proteinuria were measured using the non-invasive tail cuff method and Coomassie brilliant blue assay, respectively. TdT-mediated dUTP nick-end labeling assay was used to assess cell apoptosis in the placental tissues of PE mice.
RESULTS: NRIP1 levels were upregulated in the serum and placental tissues of patients with PE. In vitro experiments revealed that NRIP1-small interfering RNA (siRNA) increased the cell viability, migration, and invasion and reduced the cell apoptosis compared to the control siRNA. Moreover, NRIP1-siRNA activated the Wnt/β-catenin signaling pathway, as indicated by the increased Wnt3a, β-catenin, p-glycogen synthase kinase-3β, c-Myc, and cyclin D1 levels. Levels of the inflammatory factors, IL-6, TNF-α, and MMP-2, were decreased in the NRIP1-siRNA-treated group. Notably, NRIP1 downregulation improved the PE-like symptoms, inhibited the inflammatory responses, and reduced apoptosis in PE mice.
CONCLUSION: This study revealed the crucial roles of NRIP1 in PE. Our findings revealed that NRIP1 downregulation relieved PE symptoms by inhibiting cell proliferation, migration, and invasion via the Wnt/β-catenin pathway, thus providing a novel candidate for PE treatment.
