ZFIN groups reagents that target a specific nucleotide sequence, Morpholinos (MOs), CRISPRs and TALENs together and calls them sequence targeting reagents (STR).  When one of these reagents is published, ZFIN staff checks that the published sequence matches the genome and contacts authors if there are any questions about either the MO sequence or the target sequences of TALENs and CRISPRs.  The most common issues are: sequences that aren’t reported in the paper or sequences that don’t match the current genome build. Once the sequences are checked they are added to ZFIN, and are incorporated into reagent specific BLAST databases ( ) and where possible mapped onto the genome.

To map the STR targets in the genome the sequences are analyzed using Bowtie (   and mapped onto the genome for display on the ZFIN GBrowse map (  This mapping location is displayed on the individual data pages as thumbnails of the genomic region.  If a sequence doesn’t match the genome sequence an image doesn’t appear on the reagent page.  When a STR hits multiple places exactly the locations are all shown on the page as an example MO1-mir375-1,mir375-2 targets both mir375 genes ( Many Morpholinos don’t match the genome because they were either targeted to an older version of the genome, or they cross a splice site so there isn’t an uninterrupted genome match. Multiple equivalent genome matches occur for several reasons;  in some cases the reagents were designed to hit multiple genes in the same family but many other cases exist where multiple target sites seems to have been unintentional.

We always recommend double checking the target of a knockdown reagent.   If there is no image on a page it is a sign that reagent might not target as expected.

The Alliance of Genome Resources, With ZFIN as a Founding Member, Opening Doors with Version 1.0 Website Release

For the past year, ZFIN has been working with members of the other major National Institutes of Health NHGRI-funded Model Organism Database (MOD) groups, and the Gene Ontology Consortium, to establish The Alliance of Genome Resources (The Alliance; The Alliance now announces the release of the Alliance of Genome Resources website 1.0 - providing unified access to comparative genetics and genomics data from the Alliance data resources ( The MODs currently included in the Alliance in addition to ZFIN are the Saccharomyces Genome Database (SGD), FlyBase, WormBase, Mouse Genome Database (MGD), and Rat Genome Database (RGD).  In addition, the Alliance includes the Gene Ontology (GO) Consortium. These groups will merge key activities and data representations, coordinating data retrieval and analysis, within a comparative perspective. The Alliance aims to provide a synergistic integration of expertly-curated information about the functioning of cellular systems from model organisms, including zebrafish, and humans to facilitate better understanding of human biology and disease.  Other MODs and related resources will be added to the Alliance going forward.  

As part of the initial 1.0 website release, Alliance working groups have focused on the ability to easily access pages that summarize details of Genes and Diseases, with extensive representation of orthology data, and with access to multi-track JBrowse capabilities primarily for visualization of sequence data. Gene details, functional information, and disease associations are provided with a comparative perspective. As the MOD and GO teams make progress with inclusion of additional data types, the vision going forward includes the incorporation of other model organism information resources and bioinformatic tools within a common data platform, facilitating data access, comparative analyses, and cross-species data integration.

If you have questions about The Alliance in general or the Alliance website contact  ZFIN provides all the zebrafish data found at the website, so if you have questions about zebrafish data specifically, feel free to contact us directly at

Dear zebrafish researchers,


My lab has generated more than 1,500 transgenic fish lines that express Gal4 in specific organs, tissues and cells, which should be potentially useful for many purposes. You may look at these expression patterns on the web database ( However, the database contain only a couple of side-view images that were taken by a stereoscope during our routine screening. If you are interested in particular expression patterns, I recommend for you to visit my lab, perform "shelf-screen", look at them by your eyes more precisely, and find lines that are useful for your research.

Our institute provides an opportunity to support travel expenses from foreign countries to our institute. Please look at the web site of the institute.

You may apply for collaborative research NIG-JOINT A (up to 200,000JPY for travel expense) or NIG-JOINT B (up to 1,000,000JPY for travel expenses and some research money) or NIG-JOINT I (up to 500,000JPY for travel expenses for foreign researchers) (B and I are a bit competitive. You may apply for A simultaneously).

The deadline of the application is 18th December, 2017.

If you are interested in this, please contact me (


Best wishes,

Koichi Kawakami

Fish model species in human and environmental toxicology


CHAIRS: Jessica Legradi, Riccardo Massei, Jorke Kamstra


Fish models are commonly used in human and ecotoxicological research to investigate the impact of chemicals on whole organisms. In fact, many important biological functions are conserved between fish species and humans. Fish have a wide application domain, spanning from basic developmental biology, neurobiology, endocrinology to immunology. The small size of some available fish species including the zebrafish (Danio rerio) or medaka (Oryzias latipes) and their robust nature makes them ideally suited for application in automated high throughput screening. Furthermore, fish early life stages offer all the key attributes of a complex in vivo system (e.g. including metabolism), as well as the advantages of the in vitro assays, as tests can be conducted in multiwell plate formats with small sample volumes and run in short periods of time. These characteristics make them well suited for toxicity testing of environmental samples and to detect unknown contaminants in effect directed analysis (EDA). Research on fish over the last decade has been greatly facilitated by the increasing number of sequenced genomes, which are available for more than twelve species with more pending. This, together with recent advances in genetic and epigenetic studies, including gene knockout and transgenesis technologies, greatly facilitates the understanding of the molecular mechanisms of toxicity, making fish ideally suited for defining adverse outcome pathways (AOPs). Due to the large similarity with other vertebrates, there is also a growing interest in the application of fish model species in human disease etiology and early development. Fish early life stages have recently been used in several cancer genetics studies and drug discovery tests. In ecotoxicology, fish are also studied outside of the laboratory in their native environment. Prominent models for native fish models are roach (Rutilus rutilus) and rainbow trout (Oncorhynchus mykiss). Studying fish in their natural habitat allows to investigate further than simple dose-effect assessments. Within this session, we intend to show recent developments in toxicological research using a variety of different fish model species, novel systems, endpoints, assays and testing strategies. We will focus on molecular approaches that could lead to new AOPs. Results of toxicity studies of single stressors as well as complex environmental samples are of interest. Molecular effects, multigenerational effects, and population level impacts will be considered. We especially welcome presentations highlighting new Omics approaches for metabolomics, transcriptomics, epigenomics, proteomics and lipidomics, ideally linking these to phenotype for use in AOPs. The session will be interdisciplinary and bring together researchers across a wide range of research areas with the view to enhance approaches for studying adverse effects in human and wildlife.

After 2.5 years of assembly curation, the GRC presents the new zebrafish reference genome assembly, GRCz11 ( This latest assembly has been refined by the addition of nearly 1000 finished clone sequences and the resolution of more than 400 genome issues. GRCz11 shows a significant reduction in scaffold numbers and increase in scaffold N50 whilst the overall genome size was not affected. For the first time in a zebrafish assembly, GRCz11 also features alternate loci scaffolds (ALT_REF_LOCI) for representations of variant sequences. The alignments of the alternate loci scaffolds to the primary chromosomal path are also included in the GRCz11 assembly to provide the chromosome context for these alternate sequences.
