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

ABSTRACT: 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.

Placental trophoblast cells-derived exosomal microRNA-1290 promotes the interaction between endometrium and embryo by targeting LHX6

Project description:Communication between the maternal uterus and the embryo is vital for a successful pregnancy. Exosomes, subtypes of extracellular vesicles comprising many bioactive factors regulate the early stages of pregnancy, specifically during embryo implantation. Nevertheless, the mechanism by which exosomal microRNAs (miRNAs) derived from placental trophoblasts regulate embryo implantation remains elusive. Herer, we isolated and identified exosomes derived from placental trophoblasts cells (HTR8/SVneo). Subsequently, we evaluated the loading miRNA in exosomes by small RNA sequencing. This study provides novel insights into the mechanism of trophoblasts cells-derived exosomes during embryo implantation.

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.

SIRT1 binding proteins in human first trimester villi and HTR8/SVneo cells

Project description:In this study, we investigated the potential downstream target proteins in trophoblasts that were regulated by SIRT1 through modulation of acetylation. To this end, the IP products of SIRT1 in the lysate of human first-trimester villous tissue and HTR8/SVneo cells were subjected to proteomics analyses by LC-MS/MS.

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.

Effect of DHA enriched fish oil on human placental cells

Project description:The omega-3 long chain poly-unsaturated fatty acid (n-3 LCPUFA) docosahexaenoic acid (DHA) plays a central role in fetal and neonatal development in humans, in particular the development of the brain and nervous system, and this has led to numerous studies focussed on determining the effect of exposure to an increased supply of DHA on pregnancy and neonatal outcomes. The aim of this study was to determine the impact of treatment with a DHA-enriched fish-oil emulsion on fatty acid composition, proliferation rate and gene expression in human placental HTR8/SVneo cells in vitro.

Transcriptomics reveals the cytotoxicity of PM2.5 to mouse spermatocyte-derived GC-2spd cells

Project description:We have found that PM2.5 exposure can induce spermatocyte damage and inhibit GC-2spd cell proliferation in vivo and vitro studies. Transcriptomics was performed to explore the potential mechanism of PM2.5-induced reproductive toxicity. With RNA-sequencing technique, the differentially expressed genes induced by PM2.5 exposure were mainly enriched in the metabolism of xenobiotics by cytochrome P450 pathway, and Cyp1a1 was the most significantly changed gene.
