Our previous study has demonstrated that TSLP induces the invasion of human trophoblasts and plays a role in embryo implantation. The present study is undertaken to explore the mechanism by which TSLP modulates trophoblast invasion. It was revealed that TSLP treatment significantly downregulated NME1 and TIMP1 expression in both human trophoblasts and JEG-3 cells. The stimulatory effect of TSLP on trophoblast invasion was partially inhibited by either STAT3 inhibitor or STAT5 inhibitor. The downregulation of NME1 expression by TSLP was completely abrogated by STAT3 inhibitor. TIMP1 expression was attenuated by NME1 siRNA interference and enhanced by NME1 overexpression in JEG-3 cells. TSLP-stimulated increase in trophoblast invasion was partially attenuated by NME1 overexpression. Our data suggest that TSLP might downregulate NME1 expression via STAT3 signaling pathway, affecting TIMP1 expression in influencing trophoblast invasion. Our studies suggest that further studies on TSLP as a potential therapeutic for recurrent spontaneous abortion are warranted.

Preeclampsia affects 2% to 8% of pregnancies worldwide and results in significantly high maternal and perinatal morbidity and mortality, with delivery being the only definitive treatment. It is not a single disorder, but rather a manifestation of an insult(s) to the uteroplacental unit -whether maternal, fetal, and/or placental. Multiple etiologies have been implicated, including uteroplacental ischemia, maternal infection and/or inflammation, maternal obesity, sleep disorders, hydatidiform mole, maternal intestinal dysbiosis, autoimmune disorders, fetal diseases, breakdown of maternal-fetal immune tolerance, placental aging, and endocrine disorders.

Trophoblast glycoprotein (TPBG) plays a significant part in the growth of specific cancers, yet its connection to gastric cancer (GC) remains uncertain. This research seeks to analyse the fluctuation in TPBG levels in GC and evaluate how TPBG expression relates to the prognosis of GC patients. TPBG expression in GC and normal gastric tissues was investigated in The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) database, further extracting the immunohistochemistry images from HPA database and validating by Western blot.

The maintenance of early pregnancy is a complex and distinctive process, primarily characterized by critical reproductive events such as embryo implantation, trophoblasts differentiation, decidualization, and extravillous trophoblasts (EVTs) invasion etc. However, dysregulation of these essential reproductive processes can result in various pregnancy complications, including recurrent miscarriage, preeclampsia, and fetal growth restriction etc. Notably, these complications exhibit an interconnected regulatory network that suggests shared underlying pathophysiological mechanisms.

N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD), a synthetic additive widely used in the rubber industry, and its oxidized product 6PPD-quinone (6PPDQ), have garnered widespread attention as an emerging hazardous chemicals owing to their potential detrimental effects on aquatic ecosystem and human health. The effects of 6PPD and 6PPDq on the female reproductive tract, especially embryo implantation, remain unknown and were investigated in this study. We used the spheroid attachment and outgrowth models of BeWo trophoblastic spheroids and Ishikawa cells as surrogates for the human blastocyst and endometrial epithelium, respectively.

Background: Primary choriocarcinoma of the pulmonary artery is an exceedingly rare malignant neoplasm, which is often misdiagnosed due to its nonspecific clinical presentation. While this condition is characterized by the presence of trophoblastic cells, typically associated with gestational trophoblastic diseases, we encountered a case occurring in an extragenital location. The rarity of such tumors makes it challenging for clinicians to consider them in differential diagnosis, especially when the initial symptoms mimic more common conditions such as pulmonary thromboembolism (PTE).
