Endothelin-1 potentiated constriction in preeclampsia placental veins: Role of ETAR/ETBR/CaV1.2/CALD1
Background
Placenta plays a vital role in preeclampsia. The present study investigated the role of endothelin-1 (ET-1) and its receptors in preeclampsia placenta.
Method
Placenta samples were collected from normal and preeclampsia pregnancies, with one single fetus. Placental chorionic plate vessel tone was measured with DMT using vasoactive agents with or without antagonists. Role of L-type voltage-dependent calcium channels (CaV1.2) in single smooth muscle cell was detected using whole-cell patch clamp. PCR, Western blot, and ELISA was used to detect molecule expressions. Placental vessel explants and human umbilical vein smooth muscle cell (HUVSMC) were exposed to ET-1 treatment with or without antagonists. Human umbilical vein endothelial cell (HUVEC) and pregnant sheep was exposed to hypoxic condition, simulating preeclampsia.
Results
ET-1 and IRL1620 mediated stronger contractions in preeclampsia placental veins, despite unchanged ETAR and decreased ETBR expression. Comparing with control, there was higher ET-1 in umbilical plasma, maternal plasma, and placental vessels from preeclampsia. In utero hypoxia increased plasma ET-1 in fetal lambs and ewes. Hypoxia promoted ET-1 production in HUVEC. Role and expression of CaV1.2 was decreased in preeclampsia placental vessels, while high-molecular-weight caldesmon (CALD1), the marker of contractile phenotype of smooth muscle cells, was significantly increased. ET-1 treatment increased CALD1 in placental explants and in HUVSMC via ETAR/ETBR.
Conclusion
The present study firstly demonstrated ET-1 induced greater contraction in preeclampsia placental chorionic plate veins via ETAR/ETBR, instead of via weaker CaV1.2. In utero hypoxia promoted plasma ET-1 in fetal lambs and ewe, similar to that in preeclampsia. ET-1, binding with ETAR/ETBR increased CALD1, which was associated with stronger contraction in preeclampsia. The data provided important information in preeclampsia onset.
期刊介绍：
Placenta publishes high-quality original articles and invited topical reviews on all aspects of human and animal placentation, and the interactions between the mother, the placenta and fetal development. Topics covered include evolution, development, genetics and epigenetics, stem cells, metabolism, transport, immunology, pathology, pharmacology, cell and molecular biology, and developmental programming. The Editors welcome studies on implantation and the endometrium, comparative placentation, the uterine and umbilical circulations, the relationship between fetal and placental development, clinical aspects of altered placental development or function, the placental membranes, the influence of paternal factors on placental development or function, and the assessment of biomarkers of placental disorders.
