Abstract
Introduction: Preeclampsia (PE) is an immensely prevalent condition that poses a significant risk to both maternal and fetal health. It is recognized as a primary cause of perinatal morbidity and mortality. Despite extensive research efforts, the precise impact of JDP2 on trophoblast invasion and migration in the context of preeclampsia remains unclear.
Materials and methods: The present study aimed to investigate the differential expression of JDP2 between normal control and preeclampsia placentas through the use of quantitative polymerase chain reaction (qPCR), western blotting, and immunostaining techniques. Furthermore, the effects of JDP2 overexpression and silencing on the migration, invasion, and wound healing capabilities of HTR-8/SVneo cells were evaluated. In addition, this study also examined the impact of JDP2 on epithelial-mesenchymal transition (EMT)-associated biomarkers and the Wnt/β-catenin pathway.
Results: In the present investigation, it was ascertained that Jun dimerization protein 2 (JDP2) exhibited a substantial decrease in expression levels in placentae afflicted with preeclampsia in comparison to those of normal placentae. Impairment in migration and invasion was noted upon JDP2 down-regulation, whereas augmentation of migration and invasion was observed upon JDP2 overexpression in HTR-8/SVneo cells. Subsequently, western blot and immunofluorescence assays were conducted, revealing marked alterations in EMT-associated biomarkers, such as E-cadherin, N-cadherin, and β-catenin, thereby indicating that JDP2 can facilitate cell invasion by modulating the EMT process in HTR-8/SVneo cells. Finally, activation of Wnt/β-catenin signaling was observed as a result of JDP2. After that, IWR-1, a Wnt inhibitor, was used in the recovery study. IWR-1 could inhibit the role of JDP2 in promoting migration and invasion in HTR-8/SVneo cells.
Conclusion: Our findings elucidated the impact of JDP2 on trophoblast invasion and migration in preeclampsia by suppressing the EMT through the Wnt/β-catenin signaling pathway, thereby offering a potential prognostic and therapeutic biomarker for this condition.
期刊介绍：
Current Protein & Peptide Science publishes full-length/mini review articles on specific aspects involving proteins, peptides, and interactions between the enzymes, the binding interactions of hormones and their receptors; the properties of transcription factors and other molecules that regulate gene expression; the reactions leading to the immune response; the process of signal transduction; the structure and function of proteins involved in the cytoskeleton and molecular motors; the properties of membrane channels and transporters; and the generation and storage of metabolic energy. In addition, reviews of experimental studies of protein folding and design are given special emphasis. Manuscripts submitted to Current Protein and Peptide Science should cover a field by discussing research from the leading laboratories in a field and should pose questions for future studies. Original papers, research articles and letter articles/short communications are not considered for publication in Current Protein & Peptide Science.
