(Submitter supplied) Assisted reproductive technology (ART), especially in vitro fertilization (IVF) and embryo transfer have been widely applied in the treatment of human infertility. However, the accumulating evidences indicate that IVF is associated with low pregnancy rate, placental defect and the metabolic diseases in offspring. Here, we identify ectopic histone H3K4me3 in extraembryonic ectoderm (ExE) as an important reason for embryo implantation failure and extra-embryonic development abnormalities of IVF embryos. more...

(Submitter supplied) To further investigate the relationship between abnormal accumulation of H3K4me3 modification and abnormal embryo development. We injected Kdm5b siRNA, which is an H3K4me3 eraser, at the zygote (PN3-PN4) stage of NM embryos and then examined the H3K4me3 modification of extraembryonic ectoderm at E7.5.

(Submitter supplied) The great majority of embryos generated by somatic cell nuclear transfer (SCNT) display defined abnormal phenotypes after implantation, such as an increased likelihood of death and abnormal placentation. To gain better insight into the underlying mechanisms, we analyzed genome-wide gene expression profiles of day 6.5 postimplantation mouse embryos cloned from three different cell types (cumulus cells, neonatal Sertoli cells and fibroblasts). more...

(Submitter supplied) Histone modifications play critical roles in regulating developmental genes expression during embryo development in mammals1,2. However, genome-wide analysis of histone modifications in pre-implantation embryos has been impeded by technical difficulties and the scarcity of required materials. Here, by using a small-scale chromatin immunoprecipitation sequencing (ChIP-seq) method3, for the first time, we mapped the genome-wide profile of histone H3 lysine 4 trimethylation (H3K4me3) and histone H3 lysine 27 trimethylation (H3K27me3), associated with gene activation and repression respectively, in mouse pre-implantation embryos. more...

(Submitter supplied) Gametic DNA methylation is essential to the viability of the embryo and participates in developmental programming. Here, we performed a comparative epigenomic analysis of DNA methylation in spermatozoa from humans, mice, rats and mini-pigs to get insight into species specificity of the gametic epigenetic blueprint. Using data from whole-genome bisulfite sequencing (WGBS) and reduced representation bisulfite sequencing (RRBS), we compared the methylation profiles of orthologous single-CpG sites. more...

(Submitter supplied) Transcription profiling of placentomes derived from somatic cell nuclear transfer (SCNT), in vitro fertilization (IVF) and artificial insemination (AI) at or near term development was performed in order to better understand why SCNT and IVF often result in placental defects, hydrops and large offspring syndrome (LOS). Multivariate analysis of variance was used to distinguish the effects of SCNT, IVF and AI on gene expression, taking into account the effects of parturition, sex of the fetus, breed of dam, breed of fetus and disease status of the offspring. more...

(Submitter supplied) Children conceived using Assisted Reproductive Technologies (ART) have a higher incidence of growth and birth defects, attributable in part to epigenetic perturbations. Both ART and germline defects associated with parental infertility could interfere with epigenetic reprogramming events in germ cells or early embryos. Mouse models indicate that the placenta is more susceptible to the induction of epigenetic abnormalities than the embryo, and thus the placental methylome may provide a sensitive indicator of ‘at risk’ conceptuses. more...

(Submitter supplied) Although somatic cell nuclear transfer (SCNT) cloning is more efficient in bovine than in all other species tested so far, there is a high rate of pregnancy failure that has been linked to structural and functional abnormalities of the placenta. We tested the hypothesis that these changes may originate from disturbed embryo-maternal interactions in the pre-implantation period. Therefore, we evaluated the transcriptome response of the endometrium to SCNT embryos (produced from five different donor cell cultures) as compared to embryos derived from in vitro fertilization (IVF). more...

(Submitter supplied) Histone modifications are considered as fundamental epigenetic regulators that control many crucial cellular processes 1. However, whether these marks can be passed on from gametes to the next generation in mammals is a long-standing question that remains unclear. By developing a highly sensitive approach, STAR ChIP-seq, we provided a panoramic view of the landscape of H3K4me3, a histone hallmark for transcription initiation 2, from developing gametes to postimplantation embryos. more...
