Temporal Regulation of Ovine Interferon-tau Gene by the Transcription Factor Eomesodermin in the Peri-Implantation Period

Journal of Animal Reproduction and Biotechnology, 2019
Interferon tau (IFNT) regulation, an anti-luteolytic factor produced by conceptuses of the ruminant ungulates, is essential for the maintenance of early pregnancy, but a definitive mechanism for its temporal transcription has not been elucidated.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, Volume 16, Issue 6, Page 1102-1114, June 2026.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Igf1r signaling is indispensable for preimplantation development and is activated via a novel function of E-cadherin. [PDF]

PLoS Genetics, 2012
Insulin-like growth factor I receptor (Igf1r) signaling controls proliferation, differentiation, growth, and cell survival in many tissues; and its deregulated activity is involved in tumorigenesis.

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

Advanced Science, Volume 13, Issue 36, 29 June 2026.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Brg1 is required for Cdx2-mediated repression of Oct4 expression in mouse blastocysts.

PLoS ONE, 2010
During blastocyst formation the segregation of the inner cell mass (ICM) and trophectoderm is governed by the mutually antagonistic effects of the transcription factors Oct4 and Cdx2.

Pregnancy Outcomes and Postnatal Health From Transferred Mosaic Embryos Following Preimplantation Genetic Testing for Aneuploidy

iNew Medicine, Volume 2, Issue 2, June 2026.
This illustration synthesizes the methods and conclusion of this study, demonstrating that the transfer of mosaic embryos following reimplantation genetic testing for aneuploidy does not increase the risk to postnatal health. ABSTRACT Next‐generation sequencing (NGS) has increased the detection of mosaic embryos during preimplantation genetic testing ...

Predicting live birth following single euploid frozen‐embryo transfer via β‐hCG dynamics: iHOPE prognostic model with external validation

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 824-835, June 2026.
ABSTRACT Objectives To determine the prognostic value of serum β‐human chorionic gonadotropin (β‐hCG) for predicting live birth following single euploid frozen‐embryo transfer (FET), and to develop and validate a prognostic model (iHOPE) for this purpose. Methods This retrospective cohort study used data from two large fertility practices.

Phosphatase PPP1CC Regulates the First Lineage Segregation by GAS5 in Mouse Preimplantation Embryos

Cell Proliferation, Volume 59, Issue 6, June 2026.
Subcortical GAS5 directs PPP1CC phosphatase spatiotemporal positioning during mouse morula‐blastocyst transition, controlling YAP dephosphorylation to drive first embryonic lineage specification. ABSTRACT The transcriptional effector of the Hippo signalling pathway, YAP, regulates the first lineage specification in mouse preimplantation embryos ...

Exposure to Gestational Intermittent Hypoxia Does Not Impair the Metabolic Function or Accelerate the Biological Ageing Process of Offspring of Either Sex

Journal of Sleep Research, Volume 35, Issue 3, June 2026.
ABSTRACT Obstructive sleep apnea (OSA), marked by intermittent hypoxia, is associated with obesity, type 2 diabetes and metabolic associated fatty liver disease. In pregnancy, it remains underdiagnosed despite links to gestational diabetes, hypertension, and foetal growth restriction.

NuRD-dependent DNA methylation prevents ES cells from accessing a trophectoderm fate

Biology Open, 2012
Summary Embryonic Stem (ES) cells are able to give rise to the three germ layers of the embryo but are prevented from contributing to the trophoblast. The molecular nature of this barrier between embryonic and trophectodermal cell fates is not clear, but
