Epigenetic dynamics shaping melanophore and iridophore cell fate in zebrafish

Project description:We charted the global changes in the epigenetic landscape, including DNA methylation and chromatin accessibility, during neural crest differentiation into melanophores and iridophores in zebrafish to identify epigenetic determinants shaping cell type-specific gene expression. Motif enrichment in the epigenetically dynamic regions revealed putative transcription factors that might be responsible for driving pigment cell identity. Through this effort, in the relatively uncharacterized iridophores, we validate alx4a as a necessary and sufficient transcription factor for iridophore differentiation and present evidence on alx4a's potential regulatory role in guanine synthesis pathway.

Epigenetic dynamics shaping melanophore and iridophore cell fate in zebrafish.

Project description:BackgroundZebrafish pigment cell differentiation provides an attractive model for studying cell fate progression as a neural crest progenitor engenders diverse cell types, including two morphologically distinct pigment cells: black melanophores and reflective iridophores. Nontrivial classical genetic and transcriptomic approaches have revealed essential molecular mechanisms and gene regulatory circuits that drive neural crest-derived cell fate decisions. However, how the epigenetic landscape contributes to pigment cell differentiation, especially in the context of iridophore cell fate, is poorly understood.ResultsWe chart the global changes in the epigenetic landscape, including DNA methylation and chromatin accessibility, during neural crest differentiation into melanophores and iridophores to identify epigenetic determinants shaping cell type-specific gene expression.

Here, we provide a multi-omic resource for neural crest differentiation into melanophores and iridophores. This work led to the discovery and validation of iridophore-specific alx4a transcription factor.

Znf598-mediated Rps10/eS10 Ubiquitination contributes to the ribosome ubiquitination dynamics during zebrafish development

Project description:The ribosome is a translational apparatus that comprises about 80 ribosomal proteins and four rRNAs. Recent studies reported that ubiquitination of the ribosomal proteins plays a pivotal role in translational control and ribosome-associated quality control (RQC). However, little is known about the dynamics of ribosome ubiquitination under complex biological processes of multicellular organisms. To study ribosome ubiquitination during animal development, we generated a zebrafish strain that expresses a FLAG-tagged ribosomal protein Rpl36/eL36 from its endogenous locus. Combining affinity purification of ribosomes from rpl36-FLAG zebrafish embryos with immunoblotting analysis, we analyzed ribosome ubiquitination during zebrafish development. Our data showed that ubiquitination of ribosomal proteins dynamically changed as development proceeded. We further revealed that Znf598, an E3 ubiquitin ligase that triggers RQC, contributed to the ribosome ubiquitination during zebrafish development. LC-MS/MS analysis and immunoblotting analysis identified lysines 139 of ribosomal protein Rps10/eS10 as pivotal ubiquitination sites on the ribosome during development. Finally, we demonstrated that an Rps10 K139/140R mutation reduced overall ribosome ubiquitination pattern. Collectively, these results reveal dynamics and complexity of ribosome ubiquitination in zebrafish development.

Transcriptional and Epigenetic Dynamics During Specification of Human Embryonic Stem Cells

Project description:Differentiation of human embryonic stem cells (hESCs) provides a unique opportunity to study the epigenetic mechanisms that facilitate cellular transitions in a human context. To that end, we performed comprehensive transcriptional and epigenetic profiling of early populations derived through directed differentiation of hESCs representing each of the three embryonic germ layers. Integration of whole genome bisulfite sequencing, chromatin immunoprecipitation-sequencing and RNA-Sequencing reveals unique events associated with specification towards each lineage. While we observe expected dynamics such as loss of DNA methylation and gain of H3K4me1 at distal putative regulatory elements, we frequently found a germ layer specific switch to H3K27me3 at sites of high DNA methylation in the undifferentiated state. By carefully dissecting these initial events, we may be able to devise more faithful differentiation strategies and gain novel insights in to the robust rewiring of regulatory programs during cellular transitions. 10 Samples in total, 5 in replicate. To better understand the interplay of epigenetic dynamics and transcription factor binding upon in vitro specification of human embryonic stem cells we profiled OCT4, SOX2 and NANOG in hESC and the endoderm master regulatory factor FOXA2 in in vitro derived endoderm cells (dEN). To gain further insights into the relation of DNA methylation and TF binding, we carried out ChIP-bisulfite sequencing for FOXA2 in dEN. Lastly, we were interested in the fate of genes bound by FOXA2 in dEN upon further differentiation and therefore differentiated dEN further towards a hepatocyte like state and performed RNA-Seq.

Identification of chromatin states during zebrafish gastrulation using CUT&RUN and CUT&Tag

Project description:Here we describe successful implementation of CUT&Tag for profiling protein-DNA interactions in zebrafish embryos. We optimized CUT&Tag protocol to generate high resolution maps of enrichment for the histone variant H2A.Z during zebrafish development. We were able to establish dynamics of H2A.Z genomic patterning from shield stage to 24hpf embryos. Our work demonstrates the power of combining CUT&Tag with the strengths of the zebrafish system to better understand the changing embryonic chromatin landscape and its roles in shaping development.
