Embryonic development up to the blastocyst stage, implantation into the uterine wall and the development of the functional placenta are steps crucial for the establishment of normal pregnancy. Specific cells of the placenta, the trophoblast cells, invade the uterine stroma and spiral arteries, adapting them to pregnancy. Interleukin-6 is present in the human endometrium during the receptive phase and early pregnancy. Trophoblasts also produce IL-6, which was found to stimulate trophoblast invasion and migration in vitro. Here we show that the activity of MMP-9 may contribute to the observed increased invasion. In addition, in the HTR-8/SVneo trophoblast cell line IL-6 increases cell proliferation. .

Cold shock Y-box binding protein-1 (YB-1) coordinates several molecular processes between the nucleus and the cytoplasm and plays a crucial role in cell function. Moreover, it is involved in cancer progression, invasion, and metastasis. As trophoblast cells share similar characteristics with cancer cells, we hypothesized that YB-1 might also be necessary for trophoblast functionality. In samples of patients with intrauterine growth restriction, YB-1 mRNA levels were decreased, while they were increased in preeclampsia and unchanged in spontaneous abortions when compared to normal pregnant controls. Studies with overexpression and downregulation of YB-1 were performed to assess the key trophoblast processes in two trophoblast cell lines HTR8/SVneo and JEG3. Overexpression of YB-1 or exposure of trophoblast cells to recombinant YB-1 caused enhanced proliferation, while knockdown of YB-1 lead to proliferative disadvantage in JEG3 or HTR8/SVneo cells. The invasion and migration properties were affected at different degrees among the trophoblast cell lines. Trophoblast expression of genes mediating migration, invasion, apoptosis, and inflammation was altered upon YB-1 downregulation. Moreover, IL-6 secretion was excessively increased in HTR8/SVneo. Ultimately, YB-1 directly binds to NF-κB enhancer mark in HTR8/SVneo cells. Our data show that YB-1 protein is important for trophoblast cell functioning and, when downregulated, leads to trophoblast disadvantage that at least in part is mediated by NF-κB.

Abstract Well-controlled trophoblast invasion into uterine decidua is a critical process for the normal development of placenta, which is tightly regulated by various factors produced within the trophoblast-endometrial microenvironment. CXCL14 is involved in tumor growth and metastasis, and its expression in placenta is temporally regulated during pregnancy. However, the role of CXCL14 in trophoblast function during human pregnancy is not clear. In this study, by using RT-PCR through human pregnancy, we found that CXCL14 was selectively expressed at early but not late pregnancy. Immunostaining revealed that CXCL14 proteins were strongly expressed in villous cytotrophoblasts and moderately in decidualized stromal cells but very weakly in syncytiotrophoblasts and extravillous trophoblasts. The effect of CXCL14 on trophoblast invasion were examined by using human villous explants cultured on Matrigel and further proved by invasion and migration assay of primary trophoblast cells and trophoblast cell line HTR-8/SVneo. Our data showed that CXCL14 significantly inhibited outgrowth of villous explant in vitro; this effect is due to suppression of trophoblast invasion and migration through regulating matrix metalloproteinases activities, whereas the trophoblast proliferation was not affected. Moreover, because a receptor for CXCL14 has not been identified, we performed further cell-specific CXCL14 binding activities with regard to different cell types within the maternal-fetal interface. Our data revealed that CXCL14 could specifically bind to trophoblast cells but not decidual cells from the maternal-fetal interface. These results suggest that CXCL14 plays an important role in regulating trophoblast invasion through an autocrine/paracrine manner during early pregnancy.

Preeclampsia (PE) is a pregnancy-specific disorder representing a major cause of maternal and perinatal morbidity and mortality. Invasive and migratory phenotypes are acquired by trophoblasts through the process of epithelial–mesenchymal transition (EMT). Studies have shown that trophoblast EMT events are dysregulated in PE and play an important role in its development. Dysregulation of interleukin (IL)-27 and IL-27R (T-cell cytokine receptor (TCCR)/WSX -1) is relevant to PE. In this study, our results demonstrated that IL-27 did not significantly affect the proliferation and apoptosis of HTR -8/SVneo trophoblast cells, while it did significantly inhibit trophoblast invasion and migration. The expression of EMT-related proteins in HTR-8/SVneo cells and extravillous explants was detected after treatment with IL-27. Expression of epithelial markers was increased, and mesenchymal marker expression was reduced. Furthermore, we found that IL-27 could induce significant phosphorylation of Signal Transducer and Activator of Transcription 1 (STAT1) and Signal Transducer and Activator of Transcription 3 (STAT3) in a time-dependent manner in HTR-8/SVneo cells. Selective inhibitors of STAT1 (STAT1 siRNA) and STAT3 (STAT3 siRNA) were used to determine whether both STAT1 and STAT3 are required for IL-27-mediated inhibition of EMT. STAT1 inhibition in IL-27-treated cells attenuated the IL-27 effect, while the inhibition of STAT3 activation had no effect on the development of the epithelial phenotype. These results demonstrate that IL-27 may inhibit trophoblast cell migration and invasion by affecting the EMT process through an STAT1-dominant pathway in PE.
