Project description:To gain a better understanding of the diurnal variation in gene expression, we analyzed the changes in gene expression in the eye of zebrafish. Dual color oligonucleotide microarrays were used to compare total RNA harvested from eyes of adult zebrafish at midday and midnight. Statistical analyses identified 44 genes which showed significant, 2-fold or more change; 26 genes showed decreased expression at midnight (D/L ≤ 0.5) and 18 genes showed increased expression at midnight (D/L ≥ 2). Seven genes were further analyzed using qPCR. The results of qPCR identified AANAT, Mel1a1, Mel1a3, Mel1b1, Mel1b2 and Melc as genes that showed significant change in expression at dawn, dusk, midday and midnight. These results suggest that expression of melatonin receptors is subject to diurnal regulation.

Wild-type ZDR zebrafish (Danio rerio) were obtained from Animal Wonders, San Marcos, TX, and Aquatica Tropicals, Plant City, FL. Fish were conditioned on a 12 hour light/dark cycle for a minimum of 14 days before use. The design of this analysis compared the experimental to the control: midnight samples were used as experimental and midday as control. Samples were collected in triplicate per time point with each replicate representing total RNA pooled from 9 fish. Dual-color microarray was used to compare the midnight and midday samples. A statistically significant (p-value ≤ 0.05) and 2-fold or more change in an experimental sample as compared to a control indicated an up- or down-regulation in gene expression. Supplementary files: In Complete processed data file, "x" marked spots show intensities of less than 1000. In Intensity trimmed data file, all genes with signal intensities of less than 1000 in all triplicate time points were removed from the analysis.

Project description:To gain a better understanding of the factors necessary for successful CNS regeneration, a temporal analysis of the changes in gene expression in the eye caused by optic nerve injury was conducted. Dual color oligonucleotide microarrays were used to compare total RNA harvested from the eyes of sham-operated and optic nerve-injured fish at 3, 24, and 168 hours following surgery. Optic nerve injured fish are compared to sham-operated fish in order to eliminate gene expression due to non-neuronal damage and inflammatory response. Statistical analyses identified 131 genes with a 2.0-fold or greater difference in expression. Wild type zebrafish were obtained from a local pet store. Optic nerve injury was conducted using a severing model accomplished as follows. Zebrafish were anesthetized in 0.2% MS-222 dissolved in tank water. The muscles surrounding the eye were cut and the eye angled rostrally to expose the nerve. The optic nerve was then severed using microsissors without damaging the ophthalmic artery. In sham operated fish the muscles surrounding the eye were severed but the nerve was not damaged. RNA was extracted from the eye at three time points following surgery 3 hours, 24 hours, and 168 hours. RNA was pooled from multiple fish to achieve 10 ug total RNA. Samples were collected in triplicate per time point. Gene expression was analyzed on a dual color oligonucleotide array where the optic nerve injured fish were compared to sham-operated fish. Four samples of RNA were also collected from control fish and compared to each other on the microarray to confirm that processing did not create expression differences.

Project description:Purpose: Construction of 3D zebrafish spatial transcriptomics data for studying the establishment of AP axis. Methods: We performed serial bulk RNA-seq data of zebrafish embryo at three development points. Using the published spatial transcriptomics data as references, we implemented Palette to infer spatial gene expression from bulk RNA-seq data and constructed 3D embryonic spatial transcriptomics. The constructed 3D transcriptomics data was then projected on zebrafish embryo images with 3D coordinates, establishing a spatial gene expression atlas named Danio rerio Asymmetrical Maps (DreAM). Results: DreAM provides a powerful platform for visualizing gene expression patterns on zebrafish morphology and investigating spatial cell-cell interactions. Conclusions: Our work used DreAM to explore the establishment of anteroposterior (AP) axis, and identified multiple morphogen gradients that played essential roles in determining cell AP positions. Finally, we difined a hox score, and comprehensively demonstrated the spatial collinearity of Hox genes at single-cell resolution during development.

Project description:The exon junction complex (EJC) is composed of three core proteins Rbm8a, Magoh and Eif4a3 and is thought to play a role in several post-transcriptional processes. In this study we focus on understanding the role of EJC in zebrafish development. We identified transcriptome-wide binding sites of EJC in zebrafish via RNA:protein immunoprecipitation followed by deep sequencing (RIP-Seq). We find that, as in human cells, zebrafish EJC is deposited about 24 nts upstream of exon-exon junctions. We also identify transcripts regulated by Rbm8a and Magoh in zebrafish embryos using whole embryo RNA-seq from rbm8a mutant, magoh mutant and wild-type sibling embryos. This study shows that nonsense mediated mRNA decay is dysregulated in zebrafish EJC mutants.
