Metabolite profile at single-embryo level of 0 to 3h old Drosophila embryos

ABSTRACT: We used single-embryo metabolomics to characterize early developmental metabolism in Drosophila. We employed a multi-omics approach where samples were collected, homogenized in 80% methanol and the soluble fraction recover to perform targeted metabolomic whle RNA-seq was performed on the insoluble fraction to accurately stage each embryo. Then, this RNA-based staging was used to place single embryo metabolomes across the developmental trajectory. Thus, we are able to construct a highly detailed metabolomic map of embryonic development. Importantly, we validated our single-embryo metabolomics results in pools of 10 embryos. The data provide a continuous timeline of metabolite levels (and gene expression) during early development (0-3 hours) in Drosophila melanogaster. We used two genetically different lines from the Drosophila Genetic Reference Panel (DGRP) with known genetic variations in our crosses (males/DGRP_352, females/DGRP_737). RNA-seq data related to this dataset can be accessed at GEO under accession number GSE263568.

SILAC-based quantitative proteomic analysis of Drosophila gastrula stage embryos mutant for fibroblast growth factor signalin

Project description:Quantitative mass spectrometry-based proteomic analyses in combination with genetics provide powerful tools in developmental cell signaling research. Drosophila melanogaster is one of the most widely used genetic models for studying development and disease. Here we combined quantitative proteomics with genetic selection to determine global changes in the proteome upon depletion of the Heartless (Htl) Fibroblast-Growth Factor (FGF) receptor signaling in Drosophila embryos at the gastrula stage. We present a robust, single generation SILAC (stable isotope labeling with amino acids in cell culture) protocol for labeling proteins in early embryos and for the selection of homozygously mutant embryos at pre-gastrula stages using an independent genetic marker. Our analyses detected quantitative changes in the global proteome of htl mutant embryos during gastrulation. We identified distinct classes of down-regulated and up-regulated proteins and network analyses indicates functionally related groups of proteins in each class. In addition, we identified changes in the abundance of phosphopeptides. These data suggest that FGF signaling in the early embryo affects global changes in the abundance of metabolic, nucleoplasmic, cytoskeletal and transport proteins.

Gene expression profile at single embryo level of 0-3h old hybrid Drosophila embryos

Project description:We used single-embryo RNA-sequencing (RNA-seq) to characterize early zygotic gene expression in Drosophila. To assess the accurate transcriptional activation for zygotic genes, we analyze the paternal allele expression as embryos initially contain trace amounts of paternal mRNAs delivered by the sperm. For this purpose, we used two genetically different lines from the Drosophila Genetic Reference Panel (DGRP) with known genetic variations in our crosses (males/DGRP_352, females/DGRP_737). The data provide a continuous timeline of transcript levels and allele-specific gene expression during early development (≤ 3 hours) in Drosophila melanogaster. Deposited RNA-seq data is part of a multi-'omics approach and prior metabolite extraction was performed in each sample.

Epigenetic homogeneity in histone methylation underlies sperm programming for embryonic transcription

Project description:Sperm contributes genetic and epigenetic information to the embryo to efficiently support development. However, the mechanism underlying such developmental competence remains elusive. Here, we investigated whether all sperm cells have a common epigenetic configuration that primes transcriptional program for embryonic development. We show for the first time that remodelling of histones during spermiogenesis results in the retention of methylated histone H3 at the same genomic location in every sperm cell. This homogeneously methylated fraction of histone H3 in the sperm genome is maintained during early embryonic replication. Such methylated histone fraction resisting postfertilisation reprogramming marks developmental genes whose expression is perturbed upon experimental reduction of histone methylation. A similar homogeneously methylated histone H3 fraction is detected in human sperm. Altogether, we uncover a conserved mechanism of paternal epigenetic information transmission to the embryo through the homogeneous retention of methylated histone in a sperm cells population.

Benary2021 - tissue dynamics of the hepato-pancreato-biliary organ system

Project description:Single cell-based studies have revealed tremendous cellular heterogeneity in stem cell and progenitor compartments, suggesting continuous differentiation trajectories with intermixing of cells at various states of lineage commitment and notable degree of plasticity during organogenesis. The hepato-pancreato-biliary organ system relies on a small endoderm progenitor compartment that gives rise to a variety of different adult tissues, including liver, pancreas, gallbladder, and extra-hepatic bile ducts. Experimental manipulation of various developmental signals in the mouse embryo underscored important cellular plasticity in this embryonic territory. This is also reflected in the existence of human genetic syndromes as well as congenital or environmentally-caused human malformations featuring multiorgan phenotypes in liver, pancreas and gallbladder. Nevertheless, the precise lineage hierarchy and succession of events leading to the segregation of an endoderm progenitor compartment into hepatic, biliary, and pancreatic structures are not yet established. Here, we combine computational modelling approaches with genetic lineage tracing to assess the tissue dynamics accompanying the ontogeny of the hepato-pancreato-biliary organ system. We show that a multipotent progenitor domain persists at the border between liver and pancreas, even after pancreatic fate is specified, contributing to the formation of several organ derivatives, including the liver. Moreover, using single-cell RNA sequencing we define a specialized niche that possibly supports such extended cell fate plasticity.

Drosophila mRNA Interactome - Global changes of the RNA-bound proteome during the maternal-to-zygotic transition in Drosophila

Project description:The maternal-to-zygotic transition (MZT) is a process that occurs in animal embryos at the earliest developmental stages, during which maternally deposited mRNAs and other molecules are degraded and replaced by products of the zygotic genome. The zygotic genome is not activated immediately upon fertilization, therefore post-transcriptional mechanisms control the first steps of development in the early, pre-MZT embryo. To perform unbiased organism-wide identification of Drosophila RNA binding proteins (RPBs), crucial players of post-transcriptional control, we applied the recently developed RNA interactome capture method, which involves cross-linking of RNAs and their direct protein partners by UV light, purification of RNA under stringent conditions and identification of proteins by mass spectrometry. Our analysis yielded 523 high confidence RBP hits, half of which were not previously reported to bind RNA. Our comparison of the RNA interactomes of pre- and post-MZT embryos reveals a highly dynamic behavior of the RNA-bound proteome during early development, and suggests active regulation of RNA binding of some RBPs. This resource provides the first evidence of RNA binding for hundreds of Drosophila proteins, and opens new avenues for study of molecular mechanisms of early development.

Endothelial cells present an innate resistance to glucocorticoid treatment: implications for therapy of primary vasculitis

Project description:Morphogenesis of epithelial tissues relies on the precise developmental control of cell polarity and architecture. In the early Drosophila embryo, the primary epithelium forms during cellularisation, following a tightly controlled genetic programme where specific sets of genes are up-regulated. Some of them, for instance, control membrane invagination between the nuclei anchored at the apical surface of the syncytium.

The histone chaperone NASP maintains H3-H4 reservoirs in the early Drosophila embryo

Project description:Histones are essential for chromatin packaging and histone supply must be tightly regulated as excess histones are toxic. To drive the rapid cell cycles of the early embryo, however, excess histones are maternally deposited. Therefore, soluble histones must be buffered by histone chaperones but the chaperone necessary to stabilize soluble H3-H4 pools in the Drosophila embryo has yet to be identified. Here, we show that CG8223, the Drosophila ortholog of NASP, is a H3-H4-specific chaperone in the early embryo. NASP specifically binds to H3-H4 in the early embryo. We demonstrate that, while NASP is non-essential in Drosophila, NASP is maternal effect lethal gene. Embryos laid by NASP mutant mothers have a reduce rate of hatching and show defects in early embryogenesis. Critically, soluble H3-H4 pools are degraded in embryos laid by NASP mutant mothers. Our work identifies NASP as the critical H3-H4 histone chaperone in the Drosophila embryo.

Single cell atlas of the Drosophila embryonic salivary gland reveals key morphogenetic control steps

Project description:In order to investiage the morphogenetic control of early tube development in the Drosophila melanogaster embryo we performed single-cell-RNAseq-analysis of FACS-isolated early salivary gland placodal cells (stage 10-12), making up less than 0.4% of cells within the embryo to look for early tubulogeneic signatures. In order to identify salivary gland specific signals from epidermal signatures we also performed single-cell-RNAseq-analysis on FACS-isolated epidermal cells in stage 10-12 Drosophila melanogaster embryos for the purpose of differential expression anaylsis.
