The zebrafish is a small tropical fish that has become one of the favoured animal model systems for research in many areas including embryonic development, genetic analyses of disease, neural circuit function and behaviour. Portugal. Although the main focus of zebrafish research has traditionally been on developmental biology, keeping and observing zebrafish in the lab led to the identification of diseases similar to humans, such as cancer, which subsequently became a subject for study. The zebrafish (Danio rerio) is a freshwater fish belonging to the minnow family (Cyprinidae) of the order Cypriniformes. Our series, Animals in Research, profiles the top organisms used for science experimentation. The fish gets its name for its similarity to the zebra by having a few horizontal stripes on each side of the body. Share this post. Zebrafish research. Cardiovascular disease These fishes are also largely used for investigating cardiovascular diseases as they have a similar embryonic heart structure as that of human embryos. Cognition , danio rerio , … Grow incredibly fast (as much in a day as a human embryo in a month). Read more about zebrafish research in these blog posts. Water chemistry and zebrafish physiology, welfare and research reproducibility . Larval zebrafish can be housed in 96-well plates, where they can be exposed to small molecule libraries for drug discovery. They grow at an extremely fast rate, developing as much in a day as a human embryo develops in one month. Zebrafish develop ex utero and are free swimming with highly sensitive and accurate visual function already at 5 days postfertilization (dpf). Over 14,000 gene mutations have been successfully developed in zebrafish embryos. The use of zebrafish allows us to use a less sentient animal in research. The Zebrafish International Resource Center is a non-profit organization. Wei Ge, in Encyclopedia of Reproduction (Second Edition), 2018.

Clark, S.C. Ekker, in Brenner's Encyclopedia of Genetics (Second Edition), 2013. Using Zebrafish as an Experimental Model in Psychedelic Research. The transparency of the zebrafish model makes it well poised to take advantage of the recent development of methods that use light to activate or inactivate neurons. In the past 20 years, the zebrafish has gradually risen as one of the top model organisms for biological and biomedical research due to its biological advantages such as short generation time (2–3 months), high fecundity (∼200 eggs/clutch), in vitro development, transparent … Some benefits of using zebrafish for scientific research are more obvious and practical, others are very surprising. Zebrafish (Danio rerio) as a model to study gene function and novel drugs . This strongly supports the use of zebrafish as a model to study cardiovascular disease. Zebrafish have been a favorite of geneticists and developmental biologists over the past several decades due to their rapid development and developmental transparency. In contrast to mammals, zebrafish are significantly cheaper and have a number of practical advantages. Here, we discuss inflammasome research in zebrafish … The zebrafish (Danio rerio) is a fresh water fish that originates from Southeast Asia and is the premier nonmammalian vertebrate for genetics studies. In addition, many genes implicated in human neurological disorders have highly conserved orthologues in the zebrafish genome, suggesting that the biochemical events underlying pathogenesis could be recapitulated in the zebrafish nervous system. Over the past decade, zebrafish have been gaining increasing attention in behavioral neuroscience due to a number of advantages over several vertebrate and invertebrate models. The ability of zebrafish to generate many embryos every time they breed makes them especially useful for high throughput drug screening. Each female zebrafish can produce hundreds of eggs per week. Zebrafish have been proposed to represent a compromise between systems complexity and practical simplicity (Gerlai, 2012). Thank you for registering to attend 'Zebrafish in research; a public lecture', we will be in touch with further details in due course.

Zebrafish are increasingly seen as a promising model organism in which to investigate neurodevelopment because their young, or larvae, are transparent, making it possible to image the whole brain in real time. 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. The fish also develop rapidly, and researchers can simply add drugs to … Chaque mois, retrouvez un intervenant réputé sur une thématique donnée. The prices we charge for products and services are to offset some of the actual costs we incur. Zebrafish have been shown to carry highly conserved orthologues in their genome resembling many of the genes associated with various human neurological disorders. Zebrafish are increasingly being used as a model system for understanding the genetic and neuronal basis of behavior. Popular in aquariums all over the world, the zebrafish is native to South Asia. July 01, 2020 - By Nate Seltenrich. Zebrafish has been used for many years as a model to study development and disease. LAZEN beautifully illustrated this, with nearly 100 participants from all over the continent where most attendants were researchers with beginner or intermediate experience. Although the zebrafish was first developed as a model for developmental genetics, its utility has been quickly extended to many other fields of biological and biomedical sciences, including physiology, toxicology, disease modelling and drug development. Zebrafish is emerging as a model organism of choice to understand the etiology of human CHD. In this chapter, we review the zebrafish sleep literature and describe a long-term, high-throughput monitoring system for observing sleep and wake behaviors in larval zebrafish. Zebrafish produce hundreds of offspring at weekly intervals providing scientists with an ample supply of embryos to study. The Zebrafish in Biomedical Research: Biology, Husbandry, Diseases, and Research Applications is a comprehensive work that fulfills a critical need for a thorough compilation of information on this species. This is due to the large clutches that each couple produces, with up to 200 embryos every 7 days, and … Reproduction. The zebrafish research has gained further momentum in recent years due to two major technological breakthroughs: (1) completion of its genome sequencing (Howe et al., 2013) and (2) development of genome-editing technology (Gaj et al., 2013). In this chapter, we describe a simple method to identify DNA binding sites and chromatin architecture in erythrocytes from adult zebrafish using chromatin immunoprecipitation coupled with next generation sequencing. "The zebrafish is a … In its natural habitats, zebrafish prefers areas with overhanging vegetation and, as an omnivorous species, it feeds on a wide range of diet such as zooplankton, small insects, algae and other plant materials (Arunachalam et al., 2013; Spence et al., 2008). LAZEN beautifully illustrated this, with nearly 100 participants from all over the continent where most attendants were researchers with beginner or intermediate experience. Yet, following this humble beginning, why has the zebrafish developed into one of the most popular model organisms for research? This development is catalyzed by a unique combination of strengths, including the ability to isolate mutants, make transgenic animals with different cell types labeled by fluorescent markers, and record from neurons in the networks with conventional electrophysiological techniques; most importantly, transparent zebrafish larvae allow the imaging of neuronal structure and function in the living animal. Emergence of haematopoietic stem cells in the zebrafish embryo, Head of ‘Emergence of haematopoietic stem cells and cancer’ team Zebrafish larvae rely on vision, particularly cone photoreceptor function, to efficiently capture prey. Zhong, in Encyclopedia of Cardiovascular Research and Medicine, 2018. Zebrafish has emerged in the past 5 years as a model for the study of sleep and wake behaviors. Embryo-based small-molecule screens have discovered chemical probes and drug candidates for enhancing cardiovascular development, function, and regeneration. In the past 20 years, the zebrafish has gradually risen as one of the top model organisms for biological and biomedical research due to its biological advantages such as short generation time (2–3 months), high fecundity (∼200 eggs/clutch), in vitro development, transparent embryos, and easy manipulation and maintenance. This chapter discusses the scientific reasons for that popularity; describing many examples of similarities between zebrafish and mammalian function and development; how zebrafish have been used to discover novel pathways or mechanisms of toxicity; and the use of zebrafish as a model for ecological risk assessment, especially for rapid hazard testing and as bridge between laboratory and field-based studies. The combination of these new tools for linking neurons to behavior with genetic approaches and analysis of mutants make zebrafish an ideal model to bridge the challenging gaps between genes, neurons, and behavior. The zebrafish embryo allows for rapid, non-invasive and real time analysis of bacterial infections in a vertebrate host. Zebrafish have been shown to carry highly conserved orthologues in their genome resembling many of the genes associated with various human neurological disorders. Furthermore, zebrafish exhibit a rich repertoire of quantifiable behavioral responses similar to mammalian vertebrate models. Although zebrafish have become an extremely important research model, relatively little is known about the diseases that affect this species when held in captivity. Please let me know what your favorite zebrafish article is by commenting below! Danio rerio commonly known as the Zebrafish is a tropical fish belonging to the minnow family (Cyprinidae), commonly kept in aquaria and used for scientific research. Genetic studies in zebrafish have discovered novel genes and pathways in cardiovascular development and function, with close correlation with cardiovascular diseases. I have been reading a lot about zebrafish research lately and I thought it would be nice to share some of my favorite articles with you. Thank you for visiting zebrafish.org. Inflammasomes are cytosolic multiprotein complexes that regulate inflammatory responses to danger stimuli and infection, and their dysregulation is associated with an increasing number of autoinflammatory diseases. Indeed, zebrafish has been successfully used to study CHD, but other emerging zebrafish models are beginning to answer fundamental questions in atherosclerosis (e.g., Fang et al., 2014), cardiomyopathy (e.g., Hassel et al., 2009) and arrhythmias (e.g., Milan et al., 2003). Zebrafish heart regeneration occurs following injury through the dedifferentiation and proliferation of mature cardiomyocytes. Due to the Covid-19 pandemic, resource distribution has been reduced and services may be intermittent. The zebrafish vertebrate brain is evolutionarily conserved and exhibits many anatomical similarities to the mammalian brain (Tropepe & Sive, 2003). All orders will be processed in the order received. One to two inches in length, with neat black and white stripes adorning its slender body. Enthusiasm for zebrafish research is also shared by Leonard Zon, professor of paediatric medicine, at Boston Children's Hospital, part of the Harvard Medical School. This gene expression remodelling is thought to drive the EHT leading to the emergence of HSCs.

Zon, in Methods in Cell Biology, 2011. This model has therefore provided scientists with many insights, both in blood lineage development pathways and blood disorders. Applications of Zebrafish in Research The zebrafish genome has been fully sequenced to a level only achieved otherwise in humans and mice. More recently, we demonstrated that the mechanical stress exerted by the blood flow on the aorta induces a series of morphogenetic signals resulting in the activation of HSC specifying genes and the down-regulation of endothelial vascular identity. Their embryos develop very rapidly, hatching after about 50 h in controlled conditions, and their larvae begin to eat starting on day 5.Zebrafish are exotherms and are typically cultured at 28°C, though wild zebrafish have been shown to populate diverse habitats from 18°C to over 38°C. Introduction: Zebrafish (Danio rerio) is an ideal model organism for the study of vertebrate development. The fish also develop rapidly, and researchers can simply add drugs to … The zebrafish has developed into an important model organism for biomedical research over the last decades. They're an awesome model of human development. Furthermore, zebrafish share with mammals a hypocretin/orexin system that promotes wakefulness, and drugs that alter mammalian sleep have similar effects on zebrafish rest. The zebrafish, Danio rerio (formerly Brachydanio rerio), is a small freshwater fish (<4 cm in standard body length from snout to the origin of the tail fin) native to South Asia including India, Bangladesh, Pakistan, Nepal and Myanmar, where it inhabits various waters, preferably shallow and still ponds, slow-moving streams, and even rice fields (Parichy, 2015; Spence et al., 2008). How zebrafish mend the spinal cords: If nerve tracts in the animals are damaged, certain connective tissue cells, called fibroblasts (green), migrate to the wound and form scar tissue. The team's findings were recently published in the scholarly journal Nature.. Zebrafish have been used to study vertebrate development for many years, and the recent generation of zebrafish models of human neurological disease has exploited many of the resulting methods for genetic manipulation, gene expression analysis, and imaging. Using the gene-editing tool CRISPR-Cas9, the research team performed a simple experiment using a zebrafish model and separated two genes that pair up … Edward A. Burton, in Movement Disorders (Second Edition), 2015. These creatures have more in common with humans than one might suspect. Fundamental processes associated with heart functions appear to be conserved in zebrafish. From a practical or logistical standpoint, zebrafish: Can be bred very easily. They're an awesome model of human development. Emergency consultations for health, husbandry, or aquaculture will be addressed as soon as possible. Thank you.

Stephanie Padilla, Scott Glaberman, in An Introduction to Interdisciplinary Toxicology, 2020. How zebrafish mend the spinal cords: If nerve tracts in the animals are damaged, certain connective tissue cells, called fibroblasts (green), migrate to the wound and form scar tissue. The genetic underpinnings of heart development in zebrafish are highly similar to that in humans, while zebrafish presents many advantages that allow for rapid screening of candidate CHD-associated gene variants. Dr Caroline Brennan, from Queen Mary University of London, tells the NC3Rs the top five reasons why zebrafish are her model of choice. Depending on conditions, the lifespan of zebrafish ranges from 3 to 5 years. In the late 1960s, George Streisinger, who is considered the founding father of zebrafish research, first introduced this tiny slender fish as a vertebrate model for research on genetics and development at the University of Oregon. The ease of maintenance, the large number of offsprings, an option to conduct genetic screens, and the optical clarity of developing embryos constitute just a few … Zebrafish use in research has been growing steadily on the world-stage, but in South America in particular this growth is unprecedented. When using animals in research, it is important to minimise animal suffering by using the least sentient organism possible to answer the question at hand. Zebrafish can be genetically manipulated, and their genome has been fully sequenced. Zebrafish is being used in Roche research and early development for both safety and efficacy studies.
