Project description:Establish baseline expression transcriptional signatures for zebrafish developmental stages. Total RNA was extracted from single wild type zebrafish embryos at a series of different developmental stages. RNA from 12 embryos was pooled to generate a replicate.The RNA was DNase treated. Stranded RNAseq libraries were constructed using the Illumina TruSeq Stranded RNA protocol with oligo dT pulldown.This data is part of a pre-publication release.

Zebrafish 24hpf whole embryo MZezh2mutant

Project description:Polycomb group (PcG) proteins are transcriptional repressors important to maintain cell identity during embryonic development. Ezh2, the catalytic subunit of the Polycomb Repressive Complex 2, is responsible for placing the epigenetic repressive mark histone H3 lysine 27 trimethylation (H3K27me3). In contrast to results in mouse models, zebrafish embryos mutant for both maternal and zygotic ezh2 (MZezh2) can form a normal body plan at 1 day post fertilization (dpf) but die at 2 dpf, exhibiting pleiotropic phenotypes. To elucidate the specificity of PcG-mediated repression during early zebrafish development, we conducted in depth analysis of the transcriptome, epigenome, and proteome of the MZezh2 mutant embryos at 1 dpf. We found that, despite modifications in the epigenetic landscape, transcriptome and proteome analysis revealed only minor changes in gene and protein expression levels.

Proteomics analysis of zebrafish spinal cord regeneration

Project description:Label-free mass spectrometry-based quantitative proteomics was applied to a larval zebrafish spinal cord injury model, which allows axon regeneration and functional recovery within two days (days post lesion; dpl) after a spinal cord transection in 3 day-old larvae (dpf). Proteomic profiling of the lesion site was performed at 1 dpl and 2 dpl as well as corresponding age-matched unlesioned control tissue (4 dpf as control for 1 dpl; 5 dpf as control for 2 dpl).

Differentially expressed genes after inhibition of methylation

Project description:Expression microarray of livers from 4 dpf control zebrafish larvae, larvae treated with azacytidine, and ahcy mutant larvae Comparison of expression from livers obtained from ahcy+/+ treated with vehicle, ahcy+/+ treated with azacytidine, and ahcy-/- treated with vehicle. We treated larvae starting at 2 dpf with 1 mM azacytidine or vehicle control. Livers were removed at 4 dpf, RNA isolated, and double amplified.

Transcriptomic analysis reveals the involvement of canonical Wnt signaling in zebrafish gonad differentiation

Project description:Zebrafish males undergo a juvenile ovary to testis type gonadal transformation process. To understand how juvenile ovary-to-testis transformation in zebrafish is genetically regulated, we compared the transcriptomes of juvenile ovary (JO) and juvenile ovotestis (JOT) samples at 35 dpf using the Gonad Uniclone Microarray v1 (ArrayExpress ID: A-MEXP-838). We also analyzed the transcriptomes of the 32 dpf JO, 32 dpf JOT, 34 dpf JOT, and 36 dpf JOT gonads using the slightly modified Gonad Uniclone Microarray v2 and together with the 35 dpf JO and 35 dpf JOT samples, compared the JO samples against the JOT samples to identify genes that could be potentially involved in the gonad transformation process.

Effect of 17 M-NM-2-estradiol on developing zebrafish embryos

Project description:Estrogen signaling is important for vertebrate embryonic development. Here we have used zebrafish (Danio rerio) as a vertebrate model to identify estrogen regulated genes during the first 4 days of development. Zebrafish embryos were exposed to 1 M-BM-5M 17M-NM-2-estradiol from 3 hours post fertilization to 4 days post fertilization, harvested daily and subjected to RNA extraction for transcriptome analysis using microarrays. Estrogen responsive genes were analyzed with hierarchical clustering followed by gene function and tissue expression analysis. Markedly distinct sets of genes were up and down-regulated by estrogen treatment at different time points. Among these genes, only the well-known estrogenic marker vtg1 was co-regulated at all time points. Despite this, the biological functional categories targeted by estrogen were similar throughout zebrafish development. Estrogen responsive genes were enriched mainly in the liver, pancreas and brain. In conclusion, our data shows that in zebrafish distinct cohorts of E2 responsive genes are expressed in a tissue specific manner at different developmental stages. However, the biological pathways that are affected are conserved. 30 embryos were pooled as one sample and exposed to 1 M-NM-<M E2 or vehicle (0.1% DMSO) at approximately 3 hours post fertilization (hpf). At different time points, 1 dpf (24 hpf), 2 dpf (48 hpf), 3 dpf (72 hpf) and 4 dpf (104 hpf), embryos were collected for total RNA extractions. Time points 1 and 2 dpf were performed in biological triplicates of independent pools of RNA while time points 3 and 4 dpf were performed in quadruplicates.

Wild-type Zebrafish subjected to swim-training

Project description:Genome-wide microarray analysis of the effects of swim-training on zebrafish larval development. Zebrafish were subjected to swim-training from 5 days post fertilization (dpf) until 10 dpf. Subsequently, we performed a genome-wide microarray analysis of trained and control fish at 10 dpf. The goal of the project was to investigate the effects of swim-training on the gene expression level during zebrafish larval development Two-condition experiment: control vs trained fish. RNA was isolated from 10 control fish and from 10 trained fish. Subsequently, each sample was labeled with Cy3 and Cy5 in order to correct for dye bias. Control-Cy3 and Trained-Cy5 were hybridized on array 1 and Trained-Cy5 and Control-Cy3 were hybridized on array 2.

Early depletion of primordial germ cells in zebrafish promotes testis formation

Project description:The requirement for primordial germ cells (PGCs) during sexual differentiation is variable among vertebrates. It has been shown that in zebrafish complete loss of PGCs in the embryos causes exclusive male development. Further, transplantation of a single PGC into a germline deficient zebrafish embryos generates male exclusively, suggesting PGC number might be important for the ovarian fate.To explore how PGC number might regulate sexual development in zebrafish, we experimentally manipulated its number by injecting dnd MO into embryos to generate fish containing a spectrum of PGC number. The experiment was designed to compare transcriptomes between the developing trunk regions of wild type and dnd morphants at different developmental stages. The dnd MO was microinjected into one cell stage embryos to generate zebrafish with a range of PGC numbers. Transcriptomes of developing trunk regions of wild type and dnd morphants at 14 dpf and 22 dpf were analyzed.
