Project description:Using a pooled (n=10) zebrafish liver DNA, we generated base-resolution DNA methylation maps to document epigenetic landscape in zebrafish genome. Here we generated single-nucleotide resoultion DNA methylation map of zebrafish pooled liver sample using Reduced Representation Bisulfite Sequencing (RRBS)

Project description:With the emergence of zebrafish as an important model organism, a concerted effort has been made to study its transcriptome. This effort is limited by gaps in zebrafish annotation, which is especially pronounced concerning transcripts dynamically expressed during zygotic genome activation (ZGA). To date, short read sequencing has been the principal technology for zebrafish transcriptome annotation. In part because these sequence reads are too short for assembly methods to resolve the full complexity of the transcriptome, the current annotation is rudimentary. By providing direct observation of full-length transcripts, recently refined long-read sequencing platforms can dramatically improve annotation coverage and accuracy. Here, we leveraged the SMRT platform to study the early ZGA-stage zebrafish transcriptome. Our analysis revealed additional novelty and complexity in the zebrafish transcriptome, identifying 2748 high confidence novel transcripts that originated from previously unannotated loci and 1835 new isoforms in previously annotated genes.

Project description:During development, the inherited DNA methylation patterns from the parental gametes needs to be remodeled into a state compatible with embryonic pluripotency. In Zebrafish, this remodeling is achieved by the maternal methylome becoming hypomethylated to match the paternal methylome. However, how this is achieved in medaka (another teleost fish) is currently not known. Moreover, how DNA methylation remodeling is impacted in hybrid organisms, and the effects this may have on their development, is also not known. Here we address these questions by generation whole genome bisulfite sequencing data for zebrafish, medaka and zebrafish medaka embryos.

Project description:Genome-wide analysis of H3K4me3 modifications, Gata1 binding, and DNase I hypersensitivity sites in zebrafish adult red blood cells Zebrafish peripheral blood nuclei were isolated for DNase I hypersensitivity assays. Total DNA were purified using the Proteinase K digestion and Phenol-Chloroform extraction. Small DNase I fragments from the DNaseI treatement were enriched using a sucrose gradient. These ends were then labeled and amplified during library construction and for Solexa sequencing

Project description:The proteome of human brain synapses is highly complex and mutated in over 130 diseases. This complexity arose from two whole genome duplications early in the vertebrate lineage. Zebrafish are used in modelling human diseases, however its synapse proteome is uncharacterised and whether the teleost-specific genome duplication (TSGD) influenced complexity is unknown. We report the first characterisation of the proteomes and ultrastructure of central synapses in zebrafish and analyse the importance of the TSGD. The TSGD increased overall synapse proteome complexity. The Post Synaptic Density (PSD) proteome of zebrafish had lower complexity than mammals and a highly conserved set of ~1000 proteins is shared across vertebrates. PSD ultrastructural features were also conserved. Lineage-specific proteome differences indicate vertebrate species evolved distinct synapse types and functions. The datasets are a resource for a wide range of studies and have important implications for the use of zebrafish in modelling human synaptic diseases.

Project description:We have designed a zebrafish genomic microarray to identify DNA-protein interactions in the proximal promoter regions of over 11,000 zebrafish genes. Using these microarrays, together with chromatin immunoprecipitation with an antibody directed against tri-methylated lysine 4 of Histone H3, we demonstrate the feasibility of this method in zebrafish. This approach will allow investigators to determine the genomic binding locations of DNA interacting proteins during development and expedite the assembly of the genetic networks that regulate embryogenesis.

Project description:Genome-wide analysis of H3K4me3 modifications, Gata1 binding, and DNase I hypersensitivity sites in zebrafish adult red blood cells Zebrafish red cells from 10 adults were isolated for each ChIP-seq reaction. The red cells were cross-linked with formaldehyde for 20 min. DNA fragements bound by specific proteins were enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. A sample of whole cell extract (WCE) was sequenced and used as the background to determine enrichment. ChIP was performed using an antibody against total Gata1 and H3K4me3 (Millipore Cat. No. 17-614) as previously described in Lee et al 2006.
