Gene expresion analysis among young mouse embryos, aging mouse embryos and aging mouse embryos suppressed their CXCL5-CXCR2 signaling.

ABSTRACT: CXCL5-CXCR2 signailing is known as senescence-associated secretory phenotype (SASP) factor to promote cellular senescense in diverse cells. We identified CXCL5 as a SASP factor in human and mouse embryos and suppression of CXCL5-CXCR2 signaling during embryo culture improved pregnancy success in aging mice. Here, we perfomed microarray analysis using mouse blastocysts for comparing gene expression pattarns among young mouse embryos, aging mouse embryos and aging mouse embryos suppressed their CXCL5-CXCR2 signaling. As a results, gene expression pattern of CXCL5-CXCR2 signaling-suppressed aging blastocysts was closer to that of the young blastocysts as compared with aging blastocysts. In addition, cell proliferation-related pathways, such as “PI3K signaling pathway” and “RAS signaling pathway” were significantly enriched in CXCL5-suppressed blastocysts.

Comparison of gene expression profile of human blastocyst between young and aging infertility patients

Project description:The pregnancy rate of women decreases with age due to declining quality of oocytes and embryos. However, there is no established method to improve pregnancy rate in aging women. Here, we performed microarray analysis for detecting candidate genes affected the quality of aging embryos. Based on microarray analysis using young and aging human embryos at the same morphological grade, 820 genes showed > 5-fold change in aging human blastocysts. Among these genes, C-X-C motif chemokine 5 (CXCL5), one of SASP factors, showed 7.2-fold increases in aging human blastocysts. These findings indicate CXCL5, one of senescence-associated secretory phenotype (SASP) factors, partially responsible for the decline in embryo implantation potentia.

Transcriptome dynamics in early in vivo developing and in vitro produced porcine embryos

Project description:Background: The transcriptional changes around the time of embryonic genome activation in pre-implantation embryos indicate that this process is highly dynamic. In vitro produced porcine blastocysts are known to be less competent than in vivo developed blastocysts. To understand the conditions that compromise developmental competence of in vitro embryos, it is crucial to evaluate the transcriptional profile of porcine embryos during pre-implantation stages. In this study, we investigated the transcriptome dynamics in in vivo developed and in vitro produced 4-cell embryos, morulae and hatched blastocysts. Results: In vivo developed and in vitro produced embryos displayed largely similar transcriptome profiles during development. Enriched canonical pathways from the 4-cell to the morula transition that were shared between in vivo developed and in vitro produced embryos included oxidative phosphorylation and EIF2 signaling. The shared canonical pathways from the morula to the hatched blastocyst transition were 14-3-3-mediated signaling, xenobiotic metabolism general signaling pathway, and NRF2-mediated oxidative stress response. The in vivo developed and in vitro produced hatched blastocysts were compared to identify molecular signaling pathways indicative of lower developmental competence of in vitro produced hatched blastocysts. A higher metabolic rate and expression of the arginine transporter SLC7A1 were found in in vitro produced hatched blastocysts. Conclusions: Our findings suggest that embryos with compromised developmental potential are arrested at an early stage of development, while embryos developing to the hatched blastocyst stage display largely similar transcriptome profiles, irrespective of the embryo source. The hatched blastocysts derived from the in vitro fertilization-pipeline showed an enrichment in molecular signaling pathways associated with lower developmental competence, compared to the in vivo developed embryos.

Human ART culture conditions prime mouse embryos for postimplantation development

Project description:With the increasing use of Assisted Reproductive Technologies (ART) for treatment of human infertility, there is an increasing requirement for embryo culture conditions that perform as similar to nature as possible. How good the match, however, cannot be tested experimentally in human. We solved the central question of how well ART culture protocols prepare embryos for postimplantation development, under the provisions of the 'mouse embryo assay' (MEA). Our side-by-side comparison of 8 conditions [i.e., 3 culture conditions (KSOM, HTF and ISDM1) plus the in vivo system in two different mouse strains (B6 and CD1)] shows that mouse embryos cultured under ART conditions are differentially primed for postimplantation development, and that certain ART protocols outperform the oviduct. The distinct performances of blastocysts formed in ART vs. oviduct do not correlate with any significant transcriptome changes, whereas protein analysis by immunoconfocal microscopy reveals differences in the allocation of embryonic cells to the three germ layers of blastocysts. We conclude that in vitro technology is not always a defective copy of nature, and that the choice of ART protocol primes the embryos for subsequent development. 22 samples were analyzed.

Transcriptomic profiling of bovine IVF embryos revealed candidate genes and pathways involved in early embryonic development

Project description:Using microarrays, genome-wide RNA expression was profiled and compared for in vitro fertilization (IVF) - derived blastocysts and embryos undergoing degenerative development up to the same time point. Surprisingly similar transcriptomic profiles were found in degenerative embryos and blastocysts. Nonetheless, we identified 67 transcripts that significantly differed between these two groups of embryos at a 15% false discovery rate, including 33 transcripts showing at least a two-fold difference. Several signaling and metabolic pathways were found to be associated with the developmental status of embryos, among which were previously known important steroid biosynthesis and cell communication pathways in early embryonic development. Three biological replicates for each of blastocysts and degenerative embryos.

Effect of intra-cytoplasmic sperm injection (ICSI) on gene expression and development of mouse preimplantation embryos

Project description:Background: In vitro culture of preimplantation mouse embryos is associated with changes in gene expression. It is however not known if the method of fertilization affects the global pattern of gene expression. Method: We compared gene expression and development of mouse blastocysts produced by intra-cytoplasmic sperm injection and cultured in Whitten’s medium (ICSIWM) or KSOM medium with amino acids (ICSIKSOMaa) with control blastocysts flushed out of the uterus on post coital day 3.5 (In vivo). Global pattern of gene expression was assessed using the Affymetrix 430 2.0 chip. In addition we compared gene expression in embryos generated in IVF or ICSI using WM. Results: Blastocysts resulting from ICSI fertilization have a reduction in the number of trophoblastic and inner cell mass cells compared to in vivo generated embryos. Approximately 1000 genes are different between ICSI blastocyst and in vivo blastocysts; proliferation, apoptosis and morphogenetic pathways are the most common pathways altered after in vitro culture. Unexpectedly, only 41 genes were statistically different between embryo cultured in suboptimal conditions (WM) or optimal conditions (KSOMaa). Conclusion: The method of fertilization plays a more important role in shaping the transcriptome of the developing mouse embryo than the culture media used.

SCNT embryos are defective for H3K27me3 imprinting [RNA-seq]

Project description:Animal cloning can be achieved through somatic cell nuclear transfer (SCNT), yet the success rate remains very low. Recent studies have revealed two epigenetic barriers, H3K9me3 in donor cells and abnormal Xist activation, that impede SCNT reprogramming. Here we overcome both barriers by combining the use of Xist knockout donor cells and overexpressing Kdm4d, which allowed us to achieve the highest mouse cloning efficiency. However, SCNT-associated developmental defects and abnormal placenta were still observed, suggesting the existence of additional epigenetic defects in these SCNT embryos. Comparative DNA methylome analysis of IVF and SCNT blastocysts identified many abnormally methylated regions in SCNT embryos, despite successful global methylome reprogramming. Strikingly, allelic transcriptome analyses of SCNT blastocysts revealed a complete loss-of-imprinting at the H3K27me3-dependent imprinted genes, which may account for postimplantation developmental defects of SCNT embryos. This study thus not only provides the most efficient method for mouse cloning but also points the way for further improve SCNT cloning.

DNA methylation analysis and expression profiling during murine embryogenesis and in embryos deficient for DNMT3A or DNMT3B

Project description:We quantified the targets and kinetics of DNA methylation acquisition in mouse embryos, and determined the contribution of the de novo methyltransferases DNMT3A and DNMT3B to this process. We provide single-base maps of cytosine methylation by RRBS from the blastocysts to post-implantation stages and in embryos lacking DNMT3A or DNMT3B activity, and performed RNA-Seq in embryos lacking DNMT3B activity.
