The role of long noncoding RNA (LncRNA) in numerous diseases was well-established. However, its pathological significance in preeclampsia (PE) remains obscure. In this investigation, a novel low-expression LncRNA (LncRNA-LPE) was identified in PE, and the regulatory mechanism in the progression of PE was examined. We found that LncRNA-LPE was downregulated in PE compared with normal plancenta, suggesting its potential relation with the development of PE. Modulation of LncRNA-LPE expression in trophoblast cells revealed its capacity to influence the migration and invasion abilities. To identify proteins that interact with LncRNA-LPE, RNA pull-down assays, mass spectrometry, and RNA immunoprecipitation (RIP) assays were employed. And we found LncRNA-LPE could interact with the RNA-binding protein T-complex protein 1 (TCP1), which might subsequently influence the PI3K/AKT signaling pathway and lead to autophagy changing. Our results demonstrated that LncRNA-LPE facilitates the development of preeclampsia by binding to TCP1 and activating PI3K/AKT signaling pathway, indicating its potential as a morbidity marker and therapeutic target for preeclampsia. Overall design: To investigate the synergistic effect of LncRNA LPE in the regulation of preeclampsia, we established an HTR-8/SVneo cell line overexpressing LncRNA LPE. Less...
