Gestational bisphenol S impairs placental endocrine function and the fusogenic trophoblast signaling pathway

The phosphatidylinositol 3-kinase/Akt signaling pathway modulates the endocrine differentiation of trophoblast cells.

Activation of Lyn, a Src-related nonreceptor tyrosine kinase, in trophoblast cells is associated with trophoblast giant cell differentiation. The purpose of the present work was to use Lyn as a tool to identify signaling pathways regulating the endocrine differentiation of trophoblast cells. The Src homology 3 domain of Lyn was shown to display differentiation-dependent associations with other ...

Gestational pemphigoid: placental morphology and function.

Gestational pemphigoid (PG), a very rare pregnancy-associated bullous dermatosis, is associated with adverse pregnancy outcome (miscarriage, preterm delivery, foetal growth restriction). The major antigen in PG is collagen XVII (BP180). PG autoantibodies cross-react with collagen XVII in the skin and have been suggested to cause placental failure. On this basis, we evaluated clinical outcome an...

IFPA Meeting 2012 Workshop Report III: trophoblast deportation, gestational trophoblastic disease, placental insufficiency and fetal growth restriction, trophoblast over-invasion and accreta-related pathologies, placental thrombosis and fibrinolysis.

Workshops are an important part of the IFPA annual meeting as they allow for discussion of specialized topics. At IFPA meeting 2012 there were twelve themed workshops, five of which are summarized in this report. These workshops related to various aspects of placental biology but collectively covered areas of clinical research and pregnancy disorders: 1) trophoblast deportation; 2) gestational ...

Campylobacter rectus Infection Impairs Placental Function and Development in Mice

PPAR Signaling in Placental Development and Function

With the major attention to the pivotal roles of PPARs in diverse aspects of energy metabolism, the essential functions of PPARgamma and PPARbeta/delta in placental development came as a surprise and were often considered a nuisance en route to their genetic analysis. However, these findings provided an opportune entrée into placental biology. Genetic and pharmacological studies, primarily of k...
