PubMed Google Scholar. A circular representation of ohnologue pairs (Fig. Howe, K., Clark, M., Torroja, C. et al. The zebrafish genome contains few pseudogenes - genes thought to have lost their function through evolution - compared to the human genome. A second paper reports on an ongoing effort to identify and phenotype disruptive mutations in every zebrafish protein-coding gene. BETHESDA, Md., Wed., March 31, 2004 - An international research team, supported by the National Institutes of Health (NIH), today announced it has completed a high-quality, draft sequence of the genome of the laboratory rat, and has used that data to … The Zebrafish Information Network (ZFIN) is the database of genetic and genomic data for the zebrafish (Danio rerio) as a model organism.ZFIN provides a wide array of expertly curated, organized and cross-referenced zebrafish research data. The team developed a high-quality annotated zebrafish genome sequence to compare with the human reference genome. Chromosome 4 is known to be late-replicating and hybridization studies suggest that genomic copies of 5S ribosomal DNA (rDNA), which are not notably present on any other chromosome, are scattered along the long arm at high redundancy18. Successes achieved by comparing human and zebrafish genomes include discoveries ... human genome. The team identified 154 pseudogenes in the zebrafish genome, a fraction of the 13,000 or so pseudogenes found in the human genome. Sequencing of the entire genetic make-up of the zebrafish has revealed that 70 per cent of protein-coding human genes are related to genes found in the zebrafish and that 84 per cent of genes known to be associated with human disease have a zebrafish counterpart. Nature For instance, they share many features with the human systems of muscle, kidney and optical structures. Nature (in the press), Varshney, G. K. et al. Manual annotation of genomic … This pronounced abundance of type II transposable elements is unique among the sequenced vertebrate genomes, and the genome sequence shows evidence of recently active type II transposable elements. Automated annotation (Ensembl) was provided by J.E.C., S.W., J.-H.V., S.T. Internet Explorer). and B.K. A systematic genome-wide analysis of zebrafish protein-coding gene function. K.H., M.D.C., D.L.S., C.B., H.R.C., A.E. Nature 496, 498–503 (2013). KCTD13 is a major driver of mirrored neuroanatomical phenotypes of the 16p11.2 copy number variant. The zebrafish model continues to increase in popularity (Teame et al., 2019), while recent advances in genome editing technologies lower experimental barriers for non-traditional models. Based on homology to human orthologs, we identified 48 classical PTPs in the zebrafish genome. Manual annotation was produced by G.K.L., D.L., E.K., S.D., H.S., J.A.-K. and J.L. Genome duplication in the teleost fish Tetraodon nigroviridis reveals the early vertebrate proto-karyotype. The team has identified chromosomal regions unique to zebrafish that influence sex determination. Nature 485, 363–367 (2012), ADS  “The vast majority of human genes have counterparts in the zebrafish, especially genes related to human disease,” says Professor Jane Rogers, formerly of The Genome Analysis Centre (TGAC). The analyses and figures for the manuscript were produced by J.T., K.H., C.B., M.M., J.H., L.T.Q., J.A.G.-A. “This genome will allow researchers to understand how our genes work and how genetic variants can cause disease in ways that cannot be easily studied in humans or other organisms.”. A comparison of zebrafish, human and mouse regulatory elements enabled the identification of both evolutionarily conserved and species-specific regulatory sequences and networks. We also observed a very high density of small nuclear RNAs (snRNAs) on chromosome 4, and in particular those that encode spliceosome components. Fish seem to be very different from humans, with different body structures and living environments. Venous thrombosis occurs in patients with quantitative and qualitative fibrinogen disorders. Comparison to the human reference genome shows that approximately 70% of human genes have at least one obvious zebrafish orthologue. The zebrafish genome, along with the mouse and human genomes, are the only three vertebrate genomes that have been sequenced to a degree that they can be considered “finished” (Waterston et al. “Our challenge is to develop a comprehensive, functional understanding of all human genes as quickly as possible,” adds Dr. Stemple. “Armed with the zebrafish genome, we can now better understand how changes to our genomes result in disease." Each taxon has between 2,596 and 3,634 species-specific genes. The team identified 154 pseudogenes in the zebrafish genome, a fraction of the 13,000 or so pseudogenes found in the human genome. Genetica 111, 397–412 (2001), Stein, C., Caccamo, M., Laird, G. & Leptin, M. Conservation and divergence of gene families encoding components of innate immune response systems in zebrafish. a, Exon coverage (blue), stacked with coverage by snRNA exons (black). generated and provided clone libraries. “Armed with the zebrafish genome, we can now better understand how changes to our genomes result in disease.”. a and b were calculated as percentage coverage over 1-Mb overlapping windows (y axis), with a 100-kb shift between each window. The zebrafish reference genome sequence and its relationship to the human genome. c, Sequence composition (grey bars, clones; blue bars, WGS contigs). The sequence data can be found in the BioProject database, under accession number PRJNA11776. Here, I present an overview of the available technologies for analyzing tumor genomes in the zebrafish, including array based methods as well as next-generation sequencing technologies. 10), but see ref. I also discuss the ways in which zebrafish tumor genomes can be compared to human genomes using cross-species oncogenomics, which act to filter genomic noise and ultimately uncover … c and d were calculated over 100-kb windows. The largest of these families correspond to NOD-like receptor proteins19 with putative roles in innate immunity and zinc finger proteins. Nature 442, 688–691 (2006), Tobin, D. M. et al. In addition to enabling the systematic definition of a large range of early developmental phenotypes, screens in zebrafish have contributed more generally to our understanding of the factors controlling the specification of cell types, organ systems and body axes of vertebrates7,8,9. from doctors and scientists. CRISPR/Cas9 and next-generation gene-editing techniques using cytidine deaminase fused with Cas9 nickase provide fast and efficient tools … The dotted line corresponds to differences that are expected once in 100 random genome scans, and the dashed line corresponds to differences expected once in 1,000 random genome scans. The cohort of snRNAs carried on the long arm of chromosome 4 accounts for 53.2% of all snRNAs in the zebrafish genome. Zebrafish have become a popular organism for the study of vertebrate gene function1,2. In the second study, researchers armed with the zebrafish genome designed a method to assay the function of each and every gene. The zebrafish genome-sequencing project was initiated at the Wellcome Trust Sanger Institute in 2001. Zebrafish Genome Compared to Humans. b, The ohnology relationships between zebrafish chromosomes. To investigate the interesting finding that SATmap F1 fish could be either male or female while being genetically identical and heterozygous at every polymorphic locus, we sought a genetic signal for sex determination in the F2 generation, in which these polymorphisms segregate. Sign up for the Nature Briefing newsletter — what matters in science, free to your inbox daily. As a means of comparison, the human GeneBridge4 RH panel, which has been widely used, has a retention rate of 30% and a breakage frequency corresponding to 1 cR = 300 kb (5, 6). The GRC has now released a new reference assembly, GRCz11. 1a) can be challenging given (i) the two rounds of early vertebrate genome duplication (VGD1 and VGD2 (ref. 10), but see ref. and S.M.J.S. According to the genome sequencing data, the zebrafish shares 70% genes with humans and more than 84% of genes that cause human genetic diseases are present in the zebrafish, making it an excellent model for studying human gene functions, especially those that cause various human genetic diseases. HEALTH-F4-2010-242048, ZF-HEALTH). Article  the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Despite its general use, the direct comparison of the zebrafish and human oocyte transcriptomes has not been well studied. Your email address will not be published. Zebrafish have been used successfully to understand the biological activity of genes orthologous to human disease-related genes in greater detail3,4,5. Of these morbid genes, 2,601 (82%) can be related to at least one zebrafish orthologue. Nature | Kerstin Howe and Matthew D. Clark: These authors contributed equally to this work. Nature 378, 150–157 (1995), Gritsman, K. et al. Moreover, Zebrafish possess a highly developed immune system that is remarkably similar to the human one. Overlapping clone sequences were combined with WGS sequences and tied to the meiotic map, SATmap, which enabled independent placement and orientation of clones in the genome sequence. To date, only two other large genomes have been sequenced to this level: the human genome, and the mouse genome. General. However, for effective modelling of human genetic disease it is important to understand the extent to which zebrafish genes and gene structures are related to orthologous human genes. In the meantime, to ensure continued support, we are displaying the site without styles provide important models for human disease (for example, zebrafish and medaka) 2–9. The light grey shaded box corresponds to the region in which empirical P < 0.01, the dark grey shaded box corresponds to the region in which P < 0.001. LSHG-CT-2003-503496, ZF-MODELS) and Seventh Framework Programme (grant no. In addition to the chromosome 4 sex determinant, three other separate genomic regions have been identified as influencing sex determination, and these vary between the strains and even within the families studied20,21. 2a). We found approximately 7 million SNPs between the two SATmap founders. The completion of the human genome project and, more recently, the shift to Whole Exome Sequencing (WES) and Whole Genome Sequencing (WGS) has further accelerated the number of identified human … First, 71.4% of human genes have at least one zebrafish orthologue, as defined by Ensembl Compara14 (Table 2). Zebrafish is a model organism widely used for the understanding of gene function, including the fundamental basis of human disease, enabled by the presence in its genome of a high number of orthologs to human genes. Because duplicated chromosome segments in zebrafish often correspond with specific chromosome segments in mammals, it is likely that two polyploidization events occurred prior to the divergence of fish and mammal lineages. Selection of genes expressed in zebrafish microglia/macrophages for further bioinformatics analyses. 8, R251 (2007), Anderson, J. L. et al. “Our systematic analysis of zebrafish gene function will advance understanding of human disease.”, “This is a resource that will help researchers and clinicians find the gene variations responsible for our inheritance of, and susceptibility to, diseases.”, Your email address will not be published. To obtain evidence for a more complete description of protein-coding genes, we used high-throughput short-read complementary DNA sequencing and obtained a deep-coverage data set for messenger RNAs expressed in zebrafish at various stages of development and in adult tissues6. April Flowers for redOrbit.com – Your Universe Online. Comparison to the human reference genome shows that approximately 70% of human genes have at least one obvious zebrafish orthologue. These mutations, when driven to homozygosity, can produce defects in a variety of organ systems with pathologies similar to human disease. We compared the 8,083 zebrafish TSD ohnologues with human ohnologues originating from the two rounds of WGD that are common to all vertebrates and find that the two sets overlap strongly (chi-squared test, P <2 × 10−16). The subtelomeric region of the long arm shows a distinct distribution of repeat elements, with relatively fewer interspersed elements and an increased content of satellite, simple and tandem repeats that do not harbour 5S rDNA sequences. Genetically identical, heterozygous F1 fish of both sexes resulted from crossing the founders. Increasingly, zebrafish experiments are included in studies of human genetic disease, often providing independent verification of the activity of a gene implicated in a human disease3,5,10. The medaka draft genome and insights into vertebrate genome evolution. “This is just one of many examples where this project has and will advance our understanding of human disease.”. B 308, 563–577 (2007), Sola, L. & Gornung, E. Classical and molecular cytogenetics of the zebrafish, Danio rerio (Cyprinidae, Cypriniformes): an overview. The second largest orthology class contains human genes that are associated with many zebrafish genes (the ‘one-human-to-many-zebrafish’ class), with an average of 2.28 zebrafish genes for each human gene, and this probably reflects the TSD. Using morphological secondary sexual traits, we were able to score the sex of 332 genotyped F2 individuals. The zebrafish genome project at the Wellcome Sanger Institute produced the zebrafish reference assembly of the Tuebingen strain. produced the SATmap. Sequence data have been submitted to the BioProject database under accession PRJNA11776. “Our aim with this project, like with all biomedical research, is to improve human health,” says Dr. Derek Stemple, from Sanger. and C.Lang. At approximately 27 Mb, the otherwise uniform presence of the satellite repeat SAT-2 on the long arm ends abruptly. Cell Biol. The team developed a high-quality annotated zebrafish genome sequence to compare with the human reference genome. 11) followed by reciprocal loss of some ohnologs (gene dupli­ The current research team found that the main function of Titin in zebrafish may be associated with the division of cells in the body, explaining why changes to this gene can affect the way cells divide. Zebrafish Genomics; Other Genome Databases; Resources. Because duplicated chromosome segments in zebrafish often correspond with specific chromosome segments in mammals, it is likely that two polyploidization events occurred prior to the … With regards to habitat, Zebrafish are typically found in shallow ponds, canals and streams, etc (stagnant or slow-flowing waters of between 18 and 24 degrees Celsius). Some of this increased gene number is likely to be a consequence of the TSD. 5,494 genes are known to be involved in human disease and the team has identified mutations in 3,188 zebrafish gene counterparts to those associated with human disease. A similar comparison identified at least one zebrafish orthologue for 3,075 (76%) of the 4,023 human genes implicated in genome wide association studies (GWAS). Zebrafish is a popular model organism, which is widely used in developmental biology research. All of the same great people, writers and editors but now with more firepower. 2b, c). Thank you for visiting nature.com. coordinated by K.H. Genome Res. Although most chromosomes showed no significant genetic bias for a particular sex, we found that most of chromosome 16 carried a strong signal (P = 9.1 × 10−7) with a broad peak around the centromere (Fig. This number of SNPs between just two homozygous zebrafish individuals is far in excess of that seen between any two humans and is nearly one-fifth of all SNPs measured among 1,092 human diploid genomes29. Driever, W. et al. Article  The assay also allows them to explore the effect of genetic variation on zebrafish. We now have access to an enormous amount of additional research information was supported by the National Institutes of Health (NIH) grant R01 GM085318 (to J.H.P. (PDF 4709 kb). All rights reserved. The team developed a new approach based on traditional methods to more efficiently find the consequences of genetic variation in the zebrafish. Google Scholar, Amores, A. et al. This number of ancestral genes retained as duplicates in zebrafish is higher, both in absolute number and in proportion, than in other fish genomes (chi-squared test, all P < 3 × 10−5). The Zebrafish Book; Protocol Wiki; Antibody Wiki ... Cross-Species Comparison Alliance. Multiple sex-associated regions and a putative sex chromosome in zebrafish revealed by RAD mapping and population genomics. Compared to the opaque mouse embryo, where similar processes occur over days inside the mother, the zebrafish is an ideal system to observe embryogenesis live. in the zebrafish genome would be a prerequisite to recapitulate human disease but remains challenging to this day. We carried out a four-way comparison between the proteome of two mammals (human and mouse), a bird (chicken) and the zebrafish to quantify the fraction of shared and species-specific genes present in each genome (Fig. These findings highlight the importance of the zebrafish model in human disease research. All mutant alleles and data are freely available at go.nature.com/en6mos. K.A., J.W., S.P., J.C., G.T., G.H., G.G., P.H. “By modeling these human disease genes in zebrafish, we hope that resources worldwide will produce important biological information regarding the function of these genes and possibly find new targets for drug development,” she added.

Importantly for disease studies, comparison between human and zebrafish sequences reveals that 70% of human genes have at least one obvious zebrafish orthologue. Manual annotation of genomic data is extremely valuable to produce an accurate reference gene set but is expensive compared with automatic methods and so has been limited to model organisms. 1a) can be challenging given (i) the two rounds of early vertebrate genome duplication (VGD1 and VGD2 (ref. The genes in this region are highly duplicated, with 31 ancestral gene families alone providing 77.5% of the genes, the largest of which contains no less than 109 duplicates in this region. To date, the total number of discovered variants in the zebrafish genome is less than half the number found in human or mouse genomes; consequently, validation is more sparse. http://may2012.archive.ensembl.org/Danio_rerio/Info/Index, http://creativecommons.org/licenses/by-nc-sa/3.0/, The optomotor response of aging zebrafish reveals a complex relationship between visual motion characteristics and cholinergic system, Patatin primary structural properties and effects on lipid metabolism, Water and suspended sediment runoff from vineyard watersheds affecting the behavior and physiology of zebrafish, Genome-wide identification of novel long non-coding RNAs and their possible roles in hypoxic zebrafish brain, Comparison of zebrafish in vitro and in vivo developmental toxicity assessments of perfluoroalkyl acids (PFAAs).
