Trps1 regulates mouse zygotic genome activation and preimplantation embryo development via the PDE4D/AKT/CREB signaling pathway

ABSTRACT: Despite zygotic genome activation (ZGA) is crucial for early embryonic development, its regulatory mechanism is still unclear in mammals. In the present study, we demonstrate that TRPS1, a maternal factor, plays an essential role in mouse early embryogenesis by regulating the transition from 2-cell to 4-cell embryos during preimplantation development. The absence of Trps1 could leads to impaired ZGA through AKT/CREB signaling pathway. Furthermore, our findings suggest that TRPS1 may modulate the transcription of Pde4d to influence AKT and CREB phosphorylation. Interestingly, compared to Trps1 knockdown alone, co-injection of Trps1 siRNA and Pde4d mRNA significantly enhances the development rate of 4-cell embryos. Collectively, these results indicate a negative involvement of Trps1 in mouse preimplantation embryo development by targeting the PDE4D/AKT/CREB pathway to regulate ZGA.

Transcriptional targets of Trps1 in vibrissae

Project description:Mutations in TRPS1 cause trichorhinophalangeal syndrome types I and III, which are characterized by sparse scalp hair in addition to craniofacial and skeletal abnormalities. Trps1 is a vertebrate transcription factor containing nine zinc-finger domains, including a GATA-type zinc finger through which it binds DNA. Mice in which the GATA domain of Trps1 has been deleted (Trps1∆gt/∆gt) have a reduced number of pelage follicles and lack vibrissae follicles postnatally. To identify the transcriptional targets of Trps1 in the developing vibrissa follicle, we performed microarray hybridization analysis comparing expression patterns in the whisker pads of wild-type versus Trps1∆gt/∆gt embryos. We identified a number of transcription factors and Wnt inhibitors among transcripts downregulated in the mutant embryos, and several extracellular matrix proteins there were upregulated in the mutant samples. Whole whisker pads were dissected from E12.5 embryos and total RNA was isolated using the RNeasy Mini Kit (Qiagen). Triplicate RNA samples from three independent embryos of each genotype were amplified and labeled for hybridization to Affymetrix GeneChip MOE430A microarrays using Affymetrix reagents and protocols. The data output was analyzed using GeneSpring GX 10.0 commercial software (Agilent Technologies). P-values were calculated using an unpaired t-test. Expression values with a p-value less than or equal to 0.05 and a fold difference of at least 1.5 relative to wild-type baseline expression levels were considered significant.

The landscape of accessible chromatin in mammalian pre-implantation embryos (RNA-Seq)

Project description:In mammals, extensive chromatin reorganization is essential for reprogramming terminally committed gametes to a totipotent state during preimplantation development. However, the global chromatin landscape and its dynamics in this period remain unexplored. Here we report a genome-wide map of accessible chromatin in mouse preimplantation embryos using an improved assay for transposase-accessible chromatin with high throughput sequencing (ATAC-seq) approach with CRISPR/Cas9-assisted mitochondrial DNA depletion. We show that despite extensive parental asymmetry in DNA methylomes, the chromatin accessibility between the parental genomes is globally comparable after major zygotic genome activation (ZGA). Accessible chromatin in early embryos is widely shaped by transposable elements and overlaps extensively with putative cis-regulatory sequences. Unexpectedly, accessible chromatin is also found near the transcription end sites of active genes. By integrating the maps of cis-regulatory elements and single-cell transcriptomes, we construct the regulatory network of early development, which helps to identify the key modulators for lineage specification. Finally, we find that the activities of cis-regulatory elements and their associated open chromatin diminished before major ZGA. Surprisingly, we observed many loci showing non-canonical, large open chromatin domains over the entire transcribed units in minor ZGA, supporting the presence of an unusually permissive chromatin state. Together, these data reveal a unique spatiotemporal chromatin configuration that accompanies early mammalian development. Mouse preimplantation embryos were obtained from crosses of C57BL/6N and DBA/2N. RNA-seq was performed in these embryos at various stages in preimplantation development.

Lactate regulates major zygotic genome activation by H3K18 lactylation in mammals [CUT&TAG]

Project description:Lactate is present at a high level in the microenvironment of mammalian preimplantation embryos in vivo and in vitro. However, its role in preimplantation development is unclear. Here, we report that lactate is highly enriched in the nuclei of early embryos when major zygotic genome activation (ZGA) occurs in humans and mice. The inhibition of its production and uptake results in developmental arrest at the 2-cell stage, major ZGA failure, and loss of lactate-derived H3K18lac, and the abnormal phenotypes could be recapitulated by overexpression of H3K18R mutation and rescued by addition of Lac-CoA. By profiling the landscape of H3K18lac in human and mouse preimplantation embryos, we show that H3K18lac is enriched on the promoter regions of most major ZGA genes and corelates with their expressions. Taken together, we demonstrate the important role for lactate in major ZGA via H3K18lac, showing a conserved metabolic mechanism underlies preimplantation development of mammalian embryos.

DPPA2 and DPPA4 are dispensable for mouse zygotic genome activation and preimplantation development

Project description:How maternal factors in oocytes initiate zygotic genome activation (ZGA) remains elusive. Recent studies indicate that DPPA2 and DPPA4 are required for establishing a 2-cell embryo-like (2C-like) state in mouse embryonic stem cells (ESCs) in a DUX-dependent manner. These results suggest that DPPA2 and DPPA4 are essential maternal factors that regulate Dux and ZGA in embryos. By analyzing maternal knockout and maternal-zygotic knockout embryos, we unexpectedly found that Dux activation, ZGA, and preimplantation development are normal in embryos without DPPA2 or DPPA4. Thus, unlike in ESCs/2C-like cells, DPPA2 and DPPA4 are dispensable for ZGA and preimplantation development.

Comparative proteomic landscapes provide insights into mammalian preimplantation development

Project description:Understanding mammalian preimplantation development, particularly in humans, at the proteomic level remains limited. Here, we applied our Comprehensive Solution of Ultrasensitive Proteome Technology to measure the proteomic profiles of oocytes and early embryos, and identified nearly 8,000 proteins in humans and over 6,300 proteins in mice. We observed distinct proteomic dynamics before and around zygotic genome activation (ZGA) between the two species. Integrative analysis with translatome data revealed extensive divergence between translation activation and protein accumulation. Multi-omic analysis indicated that ZGA transcripts contribute to protein accumulation in blastocysts. Consequently, we identified several transcriptional regulators critical for early development in mice, thereby linking ZGA to the first lineage specification. Furthermore, single-embryo proteomics of poor quality embryos from over 100 patient-couples provided insights into preimplantation development failure. Our study may contribute to reshaping the framework of mammalian preimplantation development and opening new avenues for addressing human infertility.
