Decidual ACVR2A regulates extravillous trophoblast functions of adhesion, proliferation, migration and invasion in vitro
Publication date: April 2018Source: Pregnancy Hypertension, Volume 12Author(s): Hannah E.J. Yong, Padma Murthi, Bill Kalionis, Rosemary J. Keogh, Shaun P. BrenneckeAbstractDecidual stromal cells form the largest proportion of maternal cells at the maternal-fetal interface. Our aim was to investigate the role of the pre-eclampsia associated decidual activin receptor, ACVR2A, in regulating trophoblast functions at this interface. St-T1b and HTR-8/SVneo cell lines were used to model decidual stromal and trophoblast cells respectively. St-T1b conditioned medium inhibited HTR-8/SVneo adhesion, proliferation, migration and invas...

Reduced Methylation Downregulates CD39/ENTPD1 and ZDHHC14 to Suppress Trophoblast Cell Proliferation and Invasion: Implications in Preeclampsia
Publication date: Available online 24 March 2018Source: Pregnancy HypertensionAuthor(s): Lisha Zhu, Ruitu Lv, Lingchun Kong, Xiaotian LiAbstractPreeclampsia (PE) is a pregnancy-specific syndrome affecting up to 8% of pregnancies worldwide. While PE is a leading cause of maternal and neonatal mortality and morbidity, the pathophysiology of PE is unclear to date. Here, we have verified that dysregulation of CD39/ectonucleoside triphosphate diphosphohydrolase-1 (ENTPD1) and zinc finger DHHC-type containing 14 (ZDHHC14) via DNA methylation plays a vital role in late-onset PE pathology. Our study confirmed the differentially me...

Dysfunction of pseudogene PGK1P2 is involved in preeclampsia by acting as a competing endogenous RNA of PGK1
ConclusionsWe proved that PGK1 and PGK1P2 are a pair of ceRNAs against miR-330-5p and they play a vital role in human decidualization by regulating angiogenesis and glycolysis metabolism. The deficiency of PGK1 and PGK1P2 in the decidua jeopardizes the decidualization process and subsequently might lead to the occurrence of PE. These findings may help in promoting novel predictive, diagnostic and prognostic biomarkers of PE in future.

Loss of Akt increases soluble endoglin release from endothelial cells but not placenta
Conclusion This study confirms that the PI3K/Akt cell protection pathway is down regulated in preeclampsia, but demonstrates that this dysregulation is unlikely to be responsible for the excessive placental soluble endoglin release characteristic of preeclampsia.

O13. Catechol-O-methyltransferase deficiency leads to hypersensitivity on the pressor response against angiotensin II
Conclusion Deficiency in COMT and 2-ME are associated with the hypersensitivity on the pressor response against AngII infusion. Similar mechanisms could be relevant to pregnant status and PE.

38-OR Sexual dimorphism in the effect of inflammation on trophoblast function with preeclampsia
Conclusions We find sexual dimorphism in the effect of inflammation on placental miR-210 expression perhaps mediated by the NFκB1 pathway. This may link placental inflammation in preeclampsia to decreased mitochondrial function in pregnancies with a female fetus. Disclosures L. Myatt: None. C. Guo: None. S. Muralimanoharan: None. A. Maloyan: None.

Characterization of protocols for primary trophoblast purification, optimized for functional investigation of sFlt-1 and soluble endoglin
Conclusion In conclusion, we present a protocol that yields primary trophoblasts of high purity that produce abundant sFlt-1 and low but detectable levels of sEng. Furthermore, these cells are readily amenable to gene silencing by siRNAs and hence suitable for functional studies.
