“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. Kerstin Howe and Matthew D. Clark: These authors contributed equally to this work. 11) followed by reciprocal loss of some ohnologs (gene dupli Nature 491, 56–65 (2012), Krzywinski, M. et al. Marker placements have been normalized so that the maps can be compared. Laser injuries were used to induce … 1a) can be challenging given (i) the two rounds of early vertebrate genome duplication (VGD1 and VGD2 (ref. To date, the team has generated one or more mutations in almost 40 percent of all zebrafish genes. Article Previous Institute research found that specific mutations in the gene Titin are the potential driving force for the growth of some forms of cancer. At least 70% of human genes have at least one orthologous zebrafish gene, and 82% of the genes that have morbidity descriptions listed in Online Mendelian Inheritance in Man have at least one zebrafish ortholog (K Howe et al. Notify me of follow-up comments by email. Zebrafish genome yields significant similarity to human genome. and coordinated by J.H. Nature Genet. and R01 OD011116 (later changed to R01 RR020833) (to J.H.P.). 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. Howe, K., Clark, M., Torroja, C. et al. We also compared genes from CNAs of passaged zebrafish malignancies with aCGH results from 50 human T-ALL patients who failed induction, relapsed … CRISPR/Cas9 and next-generation gene-editing techniques using cytidine deaminase fused with Cas9 nickase provide fast and efficient tools … The assay also allows them to explore the effect of genetic variation on zebrafish. Cell Biol. Some unique features, not found in other vertebrates, can be seen in the zebrafish genome, such as having the highest repeat content in their genome sequences reported in any vertebrate species. Genome editing methods including CRISPR and Tol2. Article Human Disease . The clone and WGS sequence is tied to a high-resolution, high-density meiotic map called the Sanger AB Tübingen map (SATmap), named after the strains of zebrafish used to make the map (Supplementary Information). This was painstaking work because the zebrafish has duplicated its genome since we parted ways 400 million years ago. Internet Explorer). from doctors and scientists. We chose Tübingen as the zebrafish reference strain as it had been used extensively to identify mutations affecting embryogenesis2. All other sequenced teleost fish exhibit a much lower repeat content, with an average of less than 30%. K.A., J.W., S.P., J.C., G.T., G.H., G.G., P.H. 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). Previous studies revealed extensive contiguous or interrupted blocks of synteny, but no one-to-one correspondence, between zebrafish and human genomes (31–33). To date, only two other large genomes have been sequenced to this level: the human genome, and the mouse genome. The position of ohnologous genes between chromosomes are linked in grey (for clarity, links between chromosomes that share less than 20 ohnologues have been omitted). 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.
