Chromosomes are represented as coloured blocks. Zebrafish is known to be an advantageous model to study human disease. The Zebrafish Genome Project at the Wellcome Trust Sanger Institute was funded by Wellcome Trust grant number 098051. Furthermore, 2,059 genes are found in human, mouse and zebrafish but not in chicken, and this number is two times higher than the number of genes that are found in all amniotes but not in zebrafish (892). All other sequenced teleost fish exhibit a much lower repeat content, with an average of less than 30%. Using DCS blocks, we identified zebrafish paralogous genes that are part of DCS blocks and consistent with the locally alternating chromosomes, hence with an origin at the TSD. Connecting teleost genes and gene functions to human biology (Fig. https://medschool.vanderbilt.edu/chaz-hong-lab / Briefly, in a manner analogous to classic mutagenesis screens, we conduct high-throughput chemical screens using zebrafish to discover small molecules that specifically perturb embryonic pattern formation. This makes them a seemingly strange choice as a comparator for humans. b, The ohnology relationships between zebrafish chromosomes. and B.K. Internet Explorer). Development 123, 37–46 (1996), CAS  2b, c). 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.

Completion of the zebrafish reference genome yields strong comparisons with the human genome Researchers demonstrate today 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. Venous thrombosis occurs in patients with quantitative and qualitative fibrinogen disorders. Genome duplication in the teleost fish Tetraodon nigroviridis reveals the early vertebrate proto-karyotype. c and d were calculated over 100-kb windows. Derek L. Stemple. 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.

Sequence data have been submitted to the BioProject database under accession PRJNA11776. 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. The team identified 154 pseudogenes in the zebrafish genome, a fraction of the 13,000 or so pseudogenes found in the human genome. “Armed with the zebrafish genome, we can now better understand how changes to our genomes result in disease." Double haploid generation zero (G0) founders were sequenced to approximately 40× depth using Illumina GAII technology. The closest vertebrate species in terms of the abundance of type II transposable elements is Xenopus tropicalis (25% type II transposable elements), whereas the sequenced and annotated teleost fish (the pufferfish Takifugu and Tetraodon, the three-spined stickleback (Gasterosteus aculeatus) and the medaka (Oryzias latipes)) each possess type II transposable element coverage of less than 10%, which may relate to the fact that the zebrafish genome diverges basally from the other sequenced and annotated teleost genomes17. Our adaptable behavioral setup can monitor any small aquatic organism, particularly in multi-well format, and can thus accelerate discovery along both of these avenues. Zebrafish may seem a strange model for research related to humans—they’re not mammals, they have no arms or legs, they have different breathing systems, they live underwater, etc. CAS  25, 3–4 (2000), Vilella, A. J. et al. Zebrafish is a popular model organism, which is widely used in developmental biology research. 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. 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. All mutant alleles and data are freely available at go.nature.com/en6mos. Compared to the human genome, the zebrafish genome contains few pseudogenes, or genes thought to have lost their function through evolution. Nature 447, 714–719 (2007), Postlethwait, J. H. The zebrafish genome in context: ohnologs gone missing. “We make these zebrafish models freely available to the wider scientific and medical communities to support their effort to understand human disease and increase the pace at which medical advancements can be made.”. “There are several advantages of the zebrafish model,” says Dr. Leonard Zon, MD, Children’s Hospital of Boston MA. Zool. We wish to thank R. Durbin, E. Birney, A. Scally, C. P. Ponting, E. Busch-Nentwich and R. Kettleborough for helpful discussions, as well as F. L. Marlow and P. Aanstad for critical reading and helpful comments on manuscripts. Nature 428, 617–624 (2004), Jaillon, O. et al. The team has identified chromosomal regions unique to zebrafish that influence sex determination. Sharing the majority of genes with humans makes them an important model for understanding how genes work in health and disease. Zebrafish are members of the teleostei infraclass, a monophyletic group that is thought to have arisen approximately 340 million years ago from a common ancestor11. Detailed automatic and manual annotation provides evidence of more than 26,000 protein-coding genes, the largest gene set of any vertebrate so far sequenced. The cohort of snRNAs carried on the long arm of chromosome 4 accounts for 53.2% of all snRNAs in the zebrafish genome. A systematic genome-wide analysis of zebrafish protein-coding gene function. Genome Res. We also compared genes from CNAs of passaged zebrafish malignancies with aCGH results from 50 human T-ALL patients who failed induction, relapsed or would eventually relapse. Genetics 188, 799–808 (2011), Meyer, A. a, Orthologue genes shared between the zebrafish, human, mouse and chicken genomes, using orthology relationships from Ensembl Compara 63. Introduction. BMC Genomics 8, 195 (2007), The 1000 Genomes Project Consortium An integrated map of genetic variation from 1,092 human genomes. The number of protein-coding genes among vertebrates is relatively stable, although even closely related species may show great disparities in the nature of their protein-coding gene content. Previous assemblies were produced by M.C., who developed the first assembly integration process, and by S.R., T.E. In contrast, the zebrafish genome contains a marked excess of type II DNA transposable elements. Phenotype Summary . the new Fibromyalgia Treating by RedOrbit! 1a) can be challenging given (i) the two rounds of early vertebrate genome duplication (VGD1 and VGD2 (ref. b, Stacked repeat coverage, divided into type I transposable elements (red), type II transposable elements (grey) and other repeat types (blue), including dust, tandem and satellite repeats. Development 123, 1–36 (1996), Golzio, C. et al. Genome Res. and K.M. To accelerate the molecular analysis of zebrafish mutations and to facilitate comparisons among the genomes of zebrafish and other vertebrates, we used a homozygous diploid meiotic mapping panel to localize polymorphisms in 691 previously unmapped genes and expressed sequence tags … K.H., M.D.C., D.L.S., C.B., H.R.C., A.E. J.H.P. A large-scale zebrafish gene knockout resource for the genome-wide study of gene function. Similar graphs for the other chromosome are provided in the Supplementary Information. Comparison to the human reference genome shows that approximately 70% of human genes have at least one obvious zebrafish orthologue. It is possible that zebrafish proteins with functionally similar activities to LIF, OSM and IL-6 exist, but that their sequence divergence is so great that they cannot be recognized as orthologues. A homeobox gene essential for zebrafish notochord development. A high-quality sequence assembly of the zebrafish genome reveals the largest gene set of any vertebrate and provides information on key genomic features, and comparison to the human … Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SA, UK, Kerstin Howe, Matthew D.

Zebrafish are an important model for unlocking the mechanisms of cancer and other disease, and have already played a central role in helping to unravel the biological processes behind muscular dystrophies. In fact, 110 genes (out of 663) have no identifiable orthologues in any other sequenced teleost genome and indeed seem to be zebrafish-specific genes. We can now extend to other conditions that may be part of your everyday lives and help you on a broad level if that is what you need. Marker placements have been normalized so that the maps can be compared. First, 71.4% of human genes have at least one zebrafish orthologue, as defined by Ensembl Compara14 (Table 2). 19, 327–335 (2009), Rodríguez-Mari, A. et al. Comparison to the human reference genome shows that approximately 70% of human genes have at least one obvious zebrafish orthologue. “Our aim is to reveal the function of each gene in the zebrafish to shed light on the role of their human counterpart,” says Dr. Elisabeth Busch-Nentwich from Sanger. The grey line at 0.5 corresponds to expectation for heterozygotes (solid lines) and the grey line at 0.25 corresponds to expectation for homozygotes (dashed and dotted lines). Compared to the human genome, the zebrafish genome contains few pseudogenes, or genes thought to have lost their function through evolution. Essential to this enterprise is a high-quality genome sequence and complete annotation of zebrafish protein-coding genes with identification of their human orthologues. To investigate the number of potential disease-related genes, we compared the list of human genes possessing at least one zebrafish orthologue with the 3,176 genes bearing morbidity descriptions that are listed in the Online Mendelian Inheritance in Man (OMIM) database. Advantages of zebrafish model in vaccination tests. a, Breeding scheme for SATmap. The team has been able to create different mutations in more than 10,000 genes using the high-quality zebrafish reference genome sequence. There are many similar genes between the human genome and those of less complex animals. The physical map for the zebrafish genome has been built from four clone libraries, using restriction digest fingerprinting and alignment to mapped markers as described for the human and mouse genomes (International Human Genome Sequencing Consortium, 2001; Waterston et al., 2002). Notify me of follow-up comments by email. Comparison revealed large conserved chromosome segments. K.O., B.Z. Injury-induced thrombosis in zebrafish larvae has been used to model human coagulopathies. The goal is to create a comprehensive catalog of how changes to genes can have physical and biochemical consequences, and to give other researchers the tools to understand human diseases. Previous studies revealed extensive contiguous or interrupted blocks of synteny, but no one-to-one correspondence, between zebrafish and human genomes (31–33). A comparison of zebrafish, human and mouse regulatory elements enabled the identification of both evolutionarily conserved and species-specific regulatory sequences and networks. and P.J.d.J. Some of this increased gene number is likely to be a consequence of the TSD. Its genetic material, or genome, is about half the size of our own. 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). Comparison to the human reference genome shows that approximately 70% of human genes have at least one obvious zebrafish orthologue. They are vertebrates, however and as previously mentioned zebrafish and humans share 70% of protein-coding genes. (2021). The availability of the genome sequence, coupled with the rapid expansion of disease models and chemical screening ability, ensures that the zebrafish system has a major place in biomedicine,” Zon continued. The Zv9 assembly is a hybrid of high-quality finished clone sequence (83%) and whole-genome shotgun (WGS) sequence (17%), with a total size of 1.412 gigabases (Gb) (Table 1). When comparing human and zebrafish PPARG, two major differences between zebrafish Pparg and human PPARG were found. Howe, K., Clark, M., Torroja, C. et al. 3a). Enhancers are short DNA sequences that bind transcription factors and contact promoters in cis to activate or repress the transcription of genes into RNA (1). The Syntenic Relationship of the Zebrafish and Human Genomes W. Bradley Barbazuk,1,3 Ian Korf, 1Candy Kadavi, Joshua Heyen, Stephanie Tate,1 Edmund Wun,2 Joseph A. Bedell, 1John D. McPherson, and Stephen L. Johnson2,4 1Washington University School of Medicine Genome Sequencing Center, St. Louis, Missouri 63108 USA; 2Department of Genetics, Washington … from doctors and scientists. BOSTON— The National Institutes of Health (NIH) calls its massive genome-mapping and sequencing effort the Human Genome Project, but Homo sapiens isn't the only species whose genetic blueprint the program aims to decipher. The zebrafish reference genome sequence and its relationship to the human genome. This has allowed a greater understanding of gene function and the finding of new targets for drug treatments.”. “Several small molecules discovered using the zebrafish system have recently entered into clinical trials. Using the reference genome sequence along with high-throughput sequencing and efficient chemical mutagenesis, the project's initial results — covering 38% of all known protein-coding genes — they describe phenotypic consequences of more than 1,000 alleles. B 308, 563–577 (2007), Sola, L. & Gornung, E. Classical and molecular cytogenetics of the zebrafish, Danio rerio (Cyprinidae, Cypriniformes): an overview. Our strategy resembled the clone-by-clone sequencing approach adopted previously for both the human and mouse genome projects. It is unclear whether these genes have been lost along the evolutionary branch leading to the chicken, or whether this is due to annotation or orthology assignation errors in the chicken genome. Automated annotation (Ensembl) was provided by J.E.C., S.W., J.-H.V., S.T. and I.S. The team compared a very high-quality zebrafish genome sequence with the human reference genome. The zebrafish (Danio rerio), as a vertebrate, has the same major organs and tissues as humans. Compared with our imposing 3,200 million base pairs, brewers yeast (used for beer making) had a mere 12 million, nematode worms had 97 million, the humble fruit fly has a genome … 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. This licence does not permit commercial exploitation, and derivative works must be licensed under the same or similar licence. Genome Res. According to the first study, 70 percent of protein-coding human genes are related to zebrafish genes, and 84 percent of the genes known to be associated with human disease have a counterpart in the zebrafish genome. Google Scholar, Kettleborough, R. N. W. et al. 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. This control—or regulation—of gene expression by enhancers ensures the fine tuning of mRNA abundance in cells. 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. We found more single nucleotide polymorphisms (SNPs) in T5D than have been reported in SNP databases for any of the WIK, TU, TL, or AB lines. Near-centromeric clones are positioned at 20 Mb (BX537156), 20.2 Mb (Z10280) and 24.4 Mb (Z20450)28. Finally, a standard Ensembl gene build, incorporating filtered elements from the complementary DNA sequencing gene build, was merged with the manually curated gene models to produce a comprehensive annotation in Ensembl version 67 (http://may2012.archive.ensembl.org/Danio_rerio/Info/Index). Multiple sex-associated regions and a putative sex chromosome in zebrafish revealed by RAD mapping and population genomics. The x axis shows the chromosomal position in Mb. 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. 14 genes are duplicated in zebrafish, compared to human and 3 human orthologs were not identified. We also compared genes from CNAs of passaged zebrafish malignancies with aCGH results from 50 human T-ALL patients who failed induction, relapsed … 14, 1–10 (2004), MathSciNet  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. & Schartl, M. Gene and genome duplications in vertebrates: the one-to-four (-to-eight in fish) rule and the evolution of novel gene functions. 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. provide important models for human disease (for example, zebrafish and medaka) 2–9. 8, R251 (2007), Anderson, J. L. et al. “This high quality genome is testament to the many scientists who worked on this project and will spur biological research for years to come.”. The F1 individuals were crossed to generate a panel of F2 individuals, each with its own unique set of meiotic recombinations between AB and Tübingen (Tü) chromosomes, which were uncovered by dense genotyping with a set of 140,306 SNPs covering most of the genome.
