Epigenetics and the placenta
TLDR
Epigenetic regulation of the placenta evolves during preimplantation development and further gestation and appears to be involved in the pathogenesis of pre-eclampsia and GTD.Abstract:
results: Epigenetic regulation of the placenta evolves during preimplantation development and further gestation. Epigenetic marks, like DNA methylation, histone modifications and non-coding RNAs, affect gene expression patterns. These expression patterns, including the important parent-of-origin-dependent gene expression resulting from genomic imprinting, play a pivotal role in proper fetal and placental development. Disturbed placental epigenetics has been demonstrated in cases of intrauterine growth retardation and small for gestational age, and also appears to be involved in the pathogenesis of pre-eclampsia and GTD. Several environmental effects have been investigated so far, e.g. ethanol, oxygen tension as well as the effect of several aspects of assisted reproduction technologies on placental epigenetics. conclusions: Studies in both animals and humans have made it increasingly clear that proper epigenetic regulation of both imprinted and non-imprinted genes is important in placental development. Its disturbance, which can be caused by various environmental factors, can lead to abnormal placental development and function with possible consequences for maternal morbidity, fetal development and disease susceptibility in later life.read more

Environmental Factor-Mediated Transgenerational Inheritance of Igf2r Hypomethylation and Pulmonary Allergic Response via Targeting Dendritic Cells

TL;DR: In this paper, the authors explored the transgenerational mechanism of DEHP exposure on allergic asthma and dendritic cell (DC) homeostasis through epigenetic modification, and found that ancestral exposure of C57BL/6 mice to low-dose DEHP led to trans-generational promoter hypomethylation of the insulin-like growth factor 2 receptor (Igf2r), concomitant with enhanced Igf 2r expression and increased apoptosis prominently in CD8α+ DCs upon ligand stimulation.

TL;DR: It is reported that Cd exerts a deleterious effect on the glycosylation pattern of the placenta.

Placental Development, Evolution, and Epigenetics of Primate Pregnancies
TL;DR: It is proposed that the placenta plays a unique role in maternal– Fetal interactions due to its short life span, and how different forms of maternal–fetal interdigitation can potentially be involved in fetal growth and development is described.

Should we still offer elective freezing of all embryos in all IVF cycles
TL;DR: It is concluded that an alleged diagnosis of 'faulty endometrium' should not be used as an indication for 'freeze all', and less costly and less risky solutions such as mild ovarian stimulation, to dampen the number of oocytes and to aim for transfer of a single blastocyst, should be the preferred solution to treat women with PCOS and high responders for oocyte retrieval.

DNA methylation patterns and epigenetic memory
TL;DR: The heritability of methylation states and the secondary nature of the decision to invite or exclude methylation support the idea that DNA methylation is adapted for a specific cellular memory function in development.

DNA methyltransferases Dnmt3a and Dnmt3b are essential for de novo methylation and mammalian development.
TL;DR: It is demonstrated that two recently identified DNA methyltransferases, DnMT3a and Dnmt3b, are essential for de novo methylation and for mouse development and play important roles in normal development and disease.

Targeted mutation of the DNA methyltransferase gene results in embryonic lethality.
TL;DR: Results indicate that while a 3-fold reduction in levels of genomic m5C has no detectable effect on the viability or proliferation of ES cells in culture, a similar reduction of DNA methylation in embryos causes abnormal development and embryonic lethality.
