Down-regulated long non-coding RNA-ATB in preeclampsia and its effect on suppressing migration, proliferation, and tube formation of trophoblast cells.
Placenta 2017; 49:80-87P

Abstract

Preeclampsia is a pregnancy-specific syndrome and is one of the main causes of maternal, fetal, and neonatal morbidity and mortality. Inadequate trophoblast invasion and failure of uterine spiral artery remodeling exert a major role in the development of preeclampsia, especially the early-onset one. LncRNA-ATB is verified to be aberrantly expressed in many cancers and promote the invasion-metastasis and proliferation cascades. But little is known of lncRNA-ATB's role in preeclampsia. The aim of current study is to identify the changes of lncRNA-ATB in preeclampsia and its effects on trophoblast. The lncRNA-ATB levels were decreased in placental samples collected from preeclampsia women (n = 51) compared to those of healthy pregnant women (n = 40) by qRT-PCR analysis. Besides, it is demonstrated that lncRNA-ATB was intense stained in the trophoblast of the placenta by performing in-situ hybridization. By designing RNA interference species to suppress lncRNA-ATB and specific plasmids designed to overexpress lncRNA-ATB, we identify the role of lncRNA-ATB on the functions of trophoblast cell-line, HTR-8/SVneo. Inhibition of endogenous lncRNA-ATB decreased migration, proliferation, tube-formation of HTR-8/SVneo cells. In addition, overexpression of lncRNA-ATB promoted migration, proliferation, and tube-formation of HTR-8/SVneo cells. Therefore, lncRNA-ATB might be involved in the pathogenesis of preeclampsia by regulating the process of trophoblast invasion and endovascular formation.
