Our aim was to investigate the effect of some xenobiotics on placentation-related processes in an extravillous trophoblastic cell line (HTR-8/SVneo cells). Amphetamine, MDMA, theophylline, and fluoxetine, but not nicotine, cocaine, and caffeine, had a negative effect on cell proliferation rates, culture growth, viability, or migratory capacity. These compounds have a detrimental effect in placentation-related processes of HTR-8/SVneo cells.

There is considerable concern that naphthenic acids (NA) related to oil extraction can negatively impact reproduction in mammals, yet the mechanisms are unknown. Since placental dysfunction is central to many adverse pregnancy outcomes, the goal of this study was to determine the effects of NA exposure on placental trophoblast cell function. HTR-8/SVneo cells were exposed to a commercial technical NA mixture for 24 hours to assess transcriptional regulation of placentation-related pathways and functional assessment of migration, invasion, and angiogenesis.

Exploring the Molecular Aetiology of Preeclampsia by Massive Parallel Sequencing of DNA.

Curr Hypertens Rep

Inserm U1016, CNRS UMR8104, Institut Cochin, équipe FGTB, 24, rue du faubourg Saint-Jacques, 75014, Paris, France.

Purpose Of Review: This manuscript aims to review (for the first time) studies describing NGS sequencing of preeclampsia (PE) women's DNA.

Recent Findings: Describing markers for the early detection of PE is an essential task because, although associated molecular dysfunction begins early on during pregnancy, the disease's clinical signs usually appear late in pregnancy. Although several biochemical biomarkers have been proposed, their use in clinical environments is still limited, thereby encouraging research into PE's genetic origin.

Involvement of mTOR, JNK and PI3K in the negative effect of ethanol and metformin on the human first-trimester extravillous trophoblast HTR-8/SVneo cell line.

Our aim was to investigate the effect of two xenobiotics to which pregnant woman may be exposed, the drug of abuse ethanol (EtOH) (and its metabolite acetaldehyde (ACA)) and the therapeutic agent metformin (METF), on placentation-related processes in an extravillous trophoblastic (EVTs) cell line (HTR-8/SVneo cells). EtOH, ACA and METF (24 h) significantly reduced cell proliferation rates, culture growth, viability and migratory capacity of HTR-8/SVneo cells. Moreover, both EtOH (100 μM) and METF (1 mM) increased the apoptosis index and inhibited H-deoxy-D-glucose (H-DG) and H-folic acid (H-FA) uptake.

We previously described a negative effect of xanthohumol (XN) upon placentation-related processes. We aimed to better characterize this effect by investigating the effect of XN upon the uptake of arachidonic acid (ARA), a crucial nutrient during pregnancy, by the HTR-8/SVneo human first-trimester extravillous trophoblast cell line and its relationship with the negative effect of XN upon placentation-related processes. Uptake of C-ARA (100 nM) was time dependent and inhibited by short-term (26 minutes) or long-term (24 hours) exposure to XN.
