The elevated YTHDC1 affects trophoblastic function and induces preterm birth in ART conception via augmenting RPL37 translation

ABSTRACT: Here, it is shown that YTHDC1 was significantly increased in the human preterm placenta after ART and the murine preterm placenta after E2 exposure. Overexpression of YTHDC1 significantly promoted the proliferation, migration, and invasion of trophoblast cells, but inhibited their apoptosis. Knockdown or knockout of YTHDC1 played an opposite effect. Mechanistically, E2 promoted YTHDC1 expression through retinoid X receptor alpha (RXRA) upregulation. YTHDC1 could activate WNT and JAK/STAT signaling pathways in the human trophoblast cells. Meanwhile, YTHDC1 could fine-tone the translation of ribosomal protein L37 (RPL37) in a m6A-dependent manner, which then influence the cellular total protein synthesis. Importantly, administration of siRNA targeting YTHDC1 effectively delays preterm birth in vivo. Collectively, these findings uncover the epigenetic mechanism underlying ART preterm birth and provide a potential target for therapeutic intervention.

Placental exosomes polarize human monocyte-derived macrophages to a decidual M2-like macrophage phenotype

Project description:Macrophages are abundant in uterine mucosa during the peri-implantation phase and early pregnancy. Decidual macrophages display dynamic changes alone with pregnancy progress: During the peri-implantation phase, macrophages displayed a pro-inflammatory phenotype which facilitates embryo implantation. While, In the late firster trimester and second trimester, decidual macrophages are anti-proinflammatory which are helpful to pregnancy maintenance. Alterations in the ratio of pro-inflammatory/anti-inflammatory decidual macrophages lead to abortion, preeclampsia, and preterm birth. Placenta-derived exosomes (pEXO) are critical in the immune cell modulation such as T cell apoptosis, NK activities, and T regulatory (Treg) differentiation. However, it is unknown whether placenta-derived exosomes contribute to decidual macrophage polarization during early pregnancy. Here we report that exosomes from the placenta explant stimulate M2 macrophage polarization via exosomal miRNA-30d-5p. Mechanistically, miRNA-30d-5p polarized macrophages to M2 phenotype by inhibiting HDAC9 expression. Furthermore, the conditioned medium of pEXO-treated macrophages promoted trophoblast migration and invasion. By contrast, conditioned medium impaired the ability of endothelial cell tube formation. However, pEXO-treated macrophages have no impact on T cell proliferation. Together, we demonstrated that pEXO promoted trophoblast migration and invasion, endothelial cell migration, and attenuation of endothelial cell tube formation by polarizing macrophage to decidua-like macrophage.

HAND1 knockdown disrupts trophoblast gene expression in vitro in Bewo cells

Project description:Congenital heart disease (CHD) affects nearly 1% of births annually, and neonatal and perinatal outcomes in cases of CHD are strongly impacted by pregnancy outcomes. CHD pregnancies carry increased risk of developing pathologies of abnormal placentation including fetal growth restriction, preeclampsia, preterm birth, and stillbirth. HAND1 is a gene associated with CHD. In this study, we aimed characterize the mechanistic impacts of disrupting HAND1 on human placenta trophoblast cell lines.

Proteomics of Human Cervical Mucus Plugs

Project description:Preterm birth is a leading cause of neonatal mortality and lacks an effective therapy. Ascending microbial infections from the lower genital tract lead to infection of the placenta, amniotic fluid and fetus causing preterm birth or stillbirth. Directly in the path of an ascending infection is the cervical mucus plug (CMP), a dense mucoid structure in the cervical canal with potential antimicrobial properties. In this study, we aimed to define the components of CMP responsible for antimicrobial activity against a common lower genital tract organism associated with preterm birth and stillbirths, namely Group B Streptococcus (GBS). Using a quantitative proteomic approach, we identified antimicrobial factors in CMPs that were collected from healthy human pregnancies. This study aims to provide new insight into how the human CMP may limit ascending bacterial infection.

c-Myc supports polyploidy and prevents senescence in the murine placenta [scRNA-Seq]

Project description:Placenta is essential for reproductive success and placental abnormalities are the leading cause of low birth weight and preterm birth. The placenta includes polyploid cells that are crucial for its function. Polyploidy occurs broadly in nature but the regulators that enable polyploidy to arise in a spatiotemporally regulated manner in the placenta are unknown. We used scRNA seq to understand molecular regulators of polyploidy.

Proteomics analysis of preterm lung tissue with mass spectrometry to understand the impact of tidal volume strategy at birth

Project description:This study aimed to use a lamb model of preterm birth to investigate the impact of different tidal volume strategies, applied during positive pressure ventilation, on lung injury development. Preterm lambs were ventilated for a total of 15 minutes, followed by a 30 minute ‘rest’ period where lambs were supported via the intact placenta. A group of lambs was also euthanised at birth to act as an unventilated control group. At post-mortem lung tissue was sampled for proteomic analysis. Lung tissue samples were analysed by mass spectrometry-based proteomics using a TMT-11plex labelling approach, followed by nano-liquid chromatography coupled to an Q Exactive HF-X benchtop Orbitrap mass spectrometer in a data-dependent acquisition mode.

Immunological Sexual Dimorphism in Placenta and Its Response to Benzene Exposure

Project description:There is increasing concern regarding the adverse effects of air pollution on human health, and benzene is a major toxic compound in air pollution. Maternal benzene exposure has been associated with reproductive complications, such as preterm birth, low birth weight, and immunological and neurological complications in the offspring. However, it is poorly understood how benzene induces these complications. Our objective was to establish a full body inhalation mouse model for maternal benzene exposure that mimics clinical phenotypes observed in human populations, and characterize the maternal immune activation and placental response in our model. Here, we report that maternal immune activation triggered by benzene exposure during pregnancy leads to increased resorptions, abnormal placenta development and low birth weight of fetus. More importantly, there is a sexual dimorphic response to benzene exposure in female and male placentas. In the male placenta, the transcriptome changes reveal a more immunologically relevant profile, while females have a metabolically related profile. Furthermore, we discover the sexual dimorphic response could be a consequence of the sexual dimorphism of placenta at baseline, which indicates the significant difference between sexes in terms of the immunological processes in the placenta, both in human and mouse. Therefore, our findings established a benzene exposure mouse model and indicated the sexual dimorphism of placenta, which provides valuable reference for the future pregnancy studies.
