The effects of propylparaben on preimplantation embryo development
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-11 without embargo terms

Bioinformatics Investigation on the Role of Obox Gene Family in Preimplantation Embryo Development
<p>Preimplantation embryo development (PED) refers to the period from fertilization to implantation in mammals. This complex process is critical for successful implantation and pregnancy. Although studies on PED have been conducted, using mainly the mouse as a model organism, the gene regulatory …

Leukemia Inhibitory Factor (LIF): Murine Preimplantation Embryo Development, Implantation Rates, and Skeletal Development
… has on the skeletal development of mice. For the embryo transfer experiments, embryos were exposed to test compounds in the transfer medium only at the time of transcervical embryo transfer.</p> <p>The results obtained from this project illustrate that murine LIF stimulates the development of …

Involvement of mitochondrial transcription factor A (TFAM) in porcine gametogenesis and preimplantation embryo development
… of mitochondrial DNA (mtDNA). TFAM knockout is embryolethal. We have studied the expression and distribution of TFAM in the gametes and preimplantation embryos of a domestic pig (Sus scrofa), a livestock species of major economic significance. We hypothesized that TFAM will be expressed at high …

Effects of prepartum plane of nutrition during mid- or late gestation on beef cow BW, BCS, blood hormone concentrations, and preimplantation embryo
… cow BW, BCS, blood hormone concentrations, and preimplantation embryos. In Exp. 1, multiparous Angus and Angus x Simmental cows (n = 33; BW = 664 ± 78 kg) were fed diets formulated to provide 3 planes of nutrition: 100% NRC energy and protein requirement (REQ), 70% NRC requirement (70%REQ) or …

Uterine immune mediators and lipid profiles of the preimplantation embryo and endometrial tissue in Holstein cows supplemented with rumen-protected methionine and observed neutrophil extracellular trap (NET) formation in the bovine endometrial tissue
… risk of postpartum uterine diseases and early embryonic loss. Two experiments were conducted in order to observe the effects of nutritional supplementation on reproductive status and future embryonic development from the transition period to early lactation in Holstein cows. To investigate the …

Label-free Optical Approaches for the Non-invasive Assessment of Embryo Quality
In assisted reproductive technologies, embryo quality is a key contributor to IVF success. Accurate assessment of embryo quality remains a challenge, which if overcome, would improve the ~30% success rate of IVF, which has remained stagnant or more than a decade. Current evaluations of embryo …

Cell lineage choice during differentiation of trophoblast stem cells (tsc) is dependent on oxygen levels, and mediated by stress enzyme pathways and mitochondrial function
… cell within blastocyst, which is the stage of preimplantation embryo developed from fertilized egg. Different from another pluripotent embryonic stem cell, which is derived from inner cell mass in blastocyst and develop into fetus, multipotent TSC will specifically differentiate into all kinds …

Metabolic Regulation and Cryotolerance of In Vitro-Produced Holstein Embryos
<p><em>In vitro</em> production and transfer of embryos has become a common practice within the dairy industry to efficiently breed superior animals and meet the consumption demand of the growing population. Cyropreservation is necessary for the application of commercialized embryo transfer, …

Exploring methods to understand bovine embryo competency in vitro
The development of a preimplantation embryo is a stepwise process consisting of morphological, biochemical, and genomic changes. Much remains unknown about the attainment of embryo competency to develop and establish pregnancy. To investigate this, we compared methods of selection at the oocyte or …

Modulation of bovine preimplantation embryonic development and pregnancy by FGF2, LIF, and IGF1
In vitro embryo production enhances genetic selection through capitalizing on superior genetics, improving fertility, and increasing animal efficiency, all of which contribute to sustainable food animal production. Of the livestock species, cattle use more embryo technologies than any other. While …

Analyses of RNA dynamics in Mus musculus
… study the transcriptional dynamics in the early preimplantation mouse embryos. Unlike conventional RNA sequencing methods that can only quantify RNA abundance in each stage of the embryos, metabolic RNA sequencing can directly interrogate the transcriptional activity of each gene. This method is …

Protein phosphorylation and cell diversification in the mouse early embryo.
… into the control of compaction of the mouse preimplantation embryo. Compaction is a post-translationally controlled rearrangement of cell contacts and the cytoskeleton that occurs at the 8-cell stage of development. This re-arrangement seems to be necessary for the differentiation of the two …

The role of circadian rhythms in reproduction: development and fertility in the bmal1 null mouse.
… surviving to weaning, suggesting high knockout embryo or perinatal losses. The circadian phenotype of this mouse model was confirmed, identifying the severe disruption of circadian behavioural rhythms. Further, the growth of the bmal1 knockout mice was retarded compared with their heterozygous …

Manipulating Embryonic Development and Endometrial Function in Ruminants
Early embryogenesis is highlighted by the emergence of several embryonic end extraembryonic lineages. One such lineage is the primitive endoderm, which will eventually give rise to the yolk sac. Once believed to be a vestigial structure, the yolk sac is now believed to play a more prominent role in …

Maintaining Proper Levels of DNA Methylation Marks Through the TET Family is Critical for Normal Embryo Development in Pigs
… regulation. After fertilization, mammalian embryos undergo dynamic changes in genome-wide DNA methylation patterns and the changes are essential for normal embryo development. Ten-eleven translocation (TET) methylcytosine dioxygenases are implicated in DNA demethylation by catalyzing the …

The effects of environmentally relevant toxicants on female reproduction and embryo development
… limited studies on the effects of phthalates on preimplantation embryos. Of these studies, most have shown that exposure to a single phthalate such as Di (2-ethylhexyl) phthalate (DEHP) and other EDCs have adverse effects on proper embryo development. However, there are limited data on the …
