Project description:Purpose: The transcriptional alterations underlying physiological changes in fetal alcohol spectrum disorder are largely unidentified. Here we perform RNA sequencing on 0% and 1% EtOH (12 hpf - 5 dpf) zebrafish at 7dpf stages in order to identify significant transcriptional alterations.
Project description:The sclerotome region of the somite (labelled by nkx3.1:Gal4-VP16; UAS:NTR-mCherry) gives rise to numerous fibroblasts populations in the zebrafish trunk. We performed single cell RNA sequencing (scRNA-seq) on sclerotome-derived fibroblasts from 52 hpf embryos to determine population heterogeneity and plasticity.
Project description:In this study, we performed RNA-seq on 5 dpf livers of uhrf1-hi272 mutants and phenotypically wild-type siblings collected at 120 hpf.
Project description:This study was carried out to compare the changes in gene expression in 5 dpf zebrafish larval livers in response to mutation of the arsenic methylation gene (as3mt) - 8 bp deletion in exon 3 with and without 1 mM sodium arsenite treatment (96-120 hpf)
Project description:Quantitative proteomic data for 10 stages (including 4-cell, 256-cell, 1000-cell, Oblong, Dome, Bud, 16-hpf, 28-hpf, 3-dpf, 5-dpf) of early zebrafish development, each stage corresponds to two sets of biological repeats, and each set of biological repeats corresponds to two sets of technical repeats.
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.
Project description:Heart formation requires input from two populations of progenitor cells - the first and second heart fields - that differentiate at distinct times and create different cardiac components. The cardiac outflow tract (OFT) is built through recruitment of late-differentiating, second heart field (SHF) -derived cardiomyocytes to the arterial pole of the heart. Mechanisms responsible for selection of an appropriate number of OFT cells from the SHF remain unclear, although several lines of evidence emphasize the importance of FGF signaling in promoting this process. Here, we examine the impact of inhibition of FGF signaling on cardiac transcription profiles in an effort to identify genes operating downstream of FGF during OFT development. We compared hearts from embryos treated with the FGFR inhibitor SU5402 to the hearts from sibling embryos treated with DMSO. Two replicates were performed.
