Effect of depletion of TET3 on gene expression of HTR8-SVneo trophoblast cells.

Project description:To investigate the function TET3 in the regulation of DNA methylation, we established HTR8-SVneo cell lines in which target gene has been knocked down by siRNA. We then performed gene expression profiling analysis using data obtained from RNA-seq for three replicates.

Gene Expression Changes after Coumestrol Stimulation of Human Trophoblast Cells

Project description:Coumestrol is a potent isoflavone found in spinach and soy. To examine whether consuming large amounts of coumestrol during pregnancy affects the development of the placenta, human trophoblast cells (HTR8/Svneo) were treated with vehicle or coumestrol. Upon treatment, 3,079 genes were differentially regulated.

Comparative proteome of the BeWo and HTR8/SVneo trophoblastic cell lines

Project description:Here, we have undertaken comparative label-free quantitative (LFQ) proteomic profiling of the proteins expressed in BeWo and HTR8/SVneo cell lines using a mass spectrometry approach. We have identified 1557 proteins in total. 915 proteins were expressed in both cell lines including various transcription factors, chaperones and transport proteins. A further 338 and 304 proteins were uniquely expressed in BeWo and HTR8/SVneo cells respectively. Our bioinformatics analysis reflects the known epithelial and mesenchymal phenotypes of these cell models with principal differences in GO observed in ‘Cell junction’, ‘Catenin complex’ as well as ‘Cell adhesion’ and ‘Cell differentiation’. Our novel comparative proteomic analysis of these trophoblastic cell lines will set the stage for the use of trophoblastic cell lines for the study of pregnancy disorders and further research focusing on placental function.

High-throughput RNA sequencing of trophoblast-like cells conversion from human embryonic stem cells by BMP4

Project description:The use of models of stem cell differentiation to trophoblastic cells provides an effective perspective for understanding the early molecular events in the establishment and maintenance of human pregnancy. In combination with the newly developed deep learning technology, the automated identification of this process can greatly accelerate the contribution to relevant knowledge. Based on the transfer learning technique, we used a convolutional neural network to distinguish the microscopic images of Embryonic stem cells (ESCs) from differentiated trophoblast -like cells (TBL). To tackle the problem of insufficient training data, the strategies of data augmentation were used. The results showed that the convolutional neural network could successfully recognize trophoblast cells and stem cells automatically, but could not distinguish TBL from the immortalized trophoblast cell lines in vitro (JEG-3 and HTR8-SVneo).

PM2.5 leads to adverse pregnancy outcomes by inducing trophoblast oxidative stress and mitochondrial apoptosis via KLF9/CYP1A1 transcriptional axis

Project description:Epidemiological studies have demonstrated that fine particulate matter (PM2.5) is associated with adverse obstetric and postnatal metabolic health outcomes, but the mechanism remains unclear. This study aimed to investigate the toxicological pathways by which PM2.5 damaged placental trophoblasts in vivo and in vitro. We confirmed that PM2.5 induced adverse gestational outcomes such as increased fetal mortality rates, decreased fetal number and weight, damaged placental structure, and increased apoptosis of trophoblasts. Additionally, PM2.5 induced dysfunction of the trophoblast cell line HTR8/SVneo, including in its proliferation, apoptosis, invasion, migration and angiogenesis. Moreover, we comprehensively analyzed the transcriptional landscape of HTR8/SVneo cells exposed to PM2.5 through RNA-Seq and observed that PM2.5 triggered overexpression of pathways involved in oxidative stress and mitochondrial apoptosis to damage HTR8/SVneo cell biological functions through CYP1A1. Mechanistically, PM2.5 stimulated KLF9, a transcription factor identified as binding to CYP1A1 promoter region, which further modulated the CYP1A1-driven downstream phenotypes. Together, this study demonstrated that the KLF9/CYP1A1 axis played a crucial role in the toxic progression of PM2.5 induced adverse pregnancy outcomes, suggesting adverse effects of environmental pollution on pregnant females and putative targeted therapeutic strategies.

Hypoxia induces trophoblast migration and invasion gene pathways, a subset of which are reduced in preeclampsia

Project description:Placentation requires the proper regulation of extravillous trophoblast (EVT) migration and invasion into the decidua and maternal vasculature, processes which are initiated in physiologic hypoxic conditions. Abnormal EVT migration and/or invasion have been suggested to lead to pregnancy complications, such as preeclampsia. The objectives of this study are to determine how exposure to hypoxia impacts gene expression and cellular motility of first trimester trophoblasts, and to assess if expression of migration-associated genes is dysregulated in 2nd trimester chorionic villous samples (CVS) from preeclampsia pregnancies relative to CVS from healthy pregnancies. The 1st trimester trophoblast cell line, HTR8/SVneo, was used to investigate the relationship between hypoxia and Notch signaling in trophoblast migration and invasion. RNA sequencing and quantitative RT-PCR analyses show that exposure to hypoxia (2.5% O2) activates Notch signaling in HTR-8/SVneo. We demonstrate that exposure of HTR-8/SVneo to hypoxia induces expression of genes associated with cellular migration and invasion and increases HTR-8/SVneo cellular migration and invasion, whereas inhibition of gamma-secretase decreases Notch signaling and decreases HTR-8/SVneo migration and invasion. Analysis of RNA sequencing data from CVS of preeclampsia and uncomplicated pregnancies identified significant differentially expressed genes that are involved in cellular migration and invasion. Decreased expression of migration and invasion genes in CVS from preeclampsia pregnancies, may impair trophoblast migration and invasion in the 2nd trimester of pregnancy, resulting in the development of preeclampsia.

Gene expression profiles of trophoblast cell lines

Project description:Invasive extravillous trophoblasts (EVTs) of the human placenta are critically involved in successful pregnancy outcome since they remodel the uterine spiral arteries to increase blood flow and oxygen delivery to the placenta and the developing fetus. To gain more insights into their biological role different primary cell culture models are commonly utilised. However, access to early placental tissue may be limited and primary trophoblasts rapidly cease proliferation in vitro impairing genetic manipulation. Hence, trophoblastic cell lines have been widely used as surrogates to study EVT function. Although the cell lines share some molecular marker expression with their primary counterpart, it is unknown to what extent they recapture the invasive phenotype of EVT. Therefore, we here report the first thorough GeneChip analyses of SGHPL-5, HTR-8/SVneo, BeWo, JEG-3 and the novel ACH-3P trophoblast cells in comparison to previously analysed primary villous cytrophoblasts and extravillous trophoblasts. To identify EVT-specific gene expression signatures in trophoblast cell lines, we calcuted differentially expressed genes between pre-defined groups based on the distinct origins of the five trophoblast cell lines under investigation. Comparison 1 comprised EVT, HTR-8/Svneo and SGHPL-5 vs choriocarcinoma cells (ACH-3P, BeWo, JEG-3). Comparison 2 comprised EVT, ACH-3P, BeWo, JEG-3 vs extravillous trophoblast cell lines (HTR-8/SVneo, SGHPL-5).
