Reproduction (Cambridge, England).Reproduction.2014 Oct 30. pii: REP-14-0390. [Epub ahead of print]
Pregnancy-Specific Glycoproteins (PSG) are secreted CEACAM-related members of the immunoglobulin superfamily and are encoded by multigene families in species with haemochorial placentation. PSGs may be the most abundant trophoblast-derived proteins in maternal blood in late human pregnancy and there

A relationship has been shown between preeclampsia (PE) and intrauterine growth restriction (IUGR) and oxidative stress (OS). Since such pregnancies experience OS, we aimed to detect the distribution pattern and expression levels of a transcription factor, Nuclear factor erythroid 2-related factor-2

Elf5 counteracts precocious trophoblast differentiation by maintaining Sox2 and 3 and inhibiting Hand1 expression.

Pearton DJ1, Smith CS2, Redgate E3, van Leeuwen J4, Donnison M5, Pfeffer PL6.
Developmental biology.Dev Biol.2014 Aug 15;392(2):344-57. doi: 10.1016/j.ydbio.2014.05.012. Epub 2014 May 22.
In mice the transcription factor Elf5 is necessary for correct trophoblast development. Upon knockdown of Elf5, TS cells display neither a decrease in proliferation nor an increase in cell death but rather an increased propensity to differentiate. Such cells rapidly lose Sox2 and 3 expression, while
