Dravet syndrome is a catastrophic childhood epilepsy with early-onset seizures, delayed language and motor development, sleep disturbances, anxiety-like behaviour, severe cognitive deficit and an increased risk of fatality. It is primarily caused by de novo mutations of the SCN1A gene encoding a neuronal voltage-activated sodium channel. Zebrafish with a mutation in the SCN1A homologue recapitulate spontaneous seizure activity and mimic the convulsive behavioural movements observed in Dravet syndrome. Here, we show that phenotypic screening of drug libraries in zebrafish scn1 mutants rapidly and successfully identifies new therapeutics...

Organ toxicity, particularly liver toxicity, remains one of the major reasons for termination of drug candidates in the development pipeline as well as withdrawal or restrictions of marketed drugs. A screening-amenable alternative in vivo model such as zebrafish would therefore find immediate application in the early prediction of unacceptable organ toxicity. To identify highly upregulated genes as biomarkers of toxic responses in the zebrafish model, a set of well-characterized reference drugs that cause drug induced liver injury (DILI) in the clinic were applied to zebrafish larvae and adults...

Zebrafish represents a powerful in vivo model for phenotype-based drug discovery to identify clinically relevant small molecules. By utilizing this model, we evaluated natural product derived compounds that could potentially modulate Notch signaling that is important in both zebrafish embryogenesis and pathogenic in human cancers. A total of 234 compounds were screened using zebrafish embryos and 3 were identified to be conferring phenotypic alterations similar to embryos treated with known Notch inhibitors...

In the pharmaceutical industry, preclinical developmental and reproductive toxicity studies are conducted in laboratory animals in order to predict and prevent adverse effects of drugs on human reproductive health and development. However, these studies require a relatively large number of animals and are usually conducted late in the drug development process. Early, simple, and inexpensive screening assays could facilitate smarter decisions, reductions in animal use, and development of safe drugs. The current state and future needs for alternative models of developmental and reproductive toxicity are reviewed here...

Nonmammalian model organisms such as the nematode Caenorhabditis elegans, the fruit fly Drosophila melanogaster, and the zebrafish Danio rerio provide numerous experimental advantages for drug discovery including genetic and molecular tractability, amenability to high-throughput screening methods and reduced experimental costs and increased experimental throughput compared to traditional mammalian models. An interdisciplinary approach that strategically combines the study of nonmammalian and mammalian animal models with diverse experimental tools has and will continue to provide deep molecular and genetic understanding of human disease and will significantly enhance the discovery and application of new therapies to treat those diseases...

Excess blood vessel growth contributes to the pathology of metastatic cancers and age-related retinopathies. Despite development of improved treatments, these conditions are associated with high economic costs and drug resistance. Bevacizumab (Avastin®), a monoclonal antibody against vascular endothelial growth factor (VEGF) is used clinically to treat certain types of metastatic cancers. Unfortunately, many patients do not respond or inevitably become resistant to bevacizumab, highlighting the need for more effective anti-angiogenic drugs with novel mechanisms of action...

Zebrafish possess a highly developed immune system that is remarkably similar to the human one. Therefore, it is expected that the majority of the signalling pathways and molecules involved in the immune response of mammals exist and behave similarly in fish. The innate antiviral response depends on the recognition of viral components by host cells. Pattern recognition receptors initiate antimicrobial defence mechanisms via several well-conserved signalling pathways. In this paper, we review current knowledge of the antiviral innate immune response in zebrafish by considering the main molecules that have been characterized and the infection models used for the in vivo study of the antiviral innate immune response...

Zebrafish have become a popular animal model for behavioural pharmacology due to their small size, rapid development, and amenability to high throughput behavioural drug screens. Furthermore, water-soluble compounds can be administered via immersion of the fish in the drug solution, which provides a non-invasive drug delivery method. Numerous studies have demonstrated stimulant effects of alcohol. Diazepam and caffeine, on the other hand have been found to have inhibitory effect on locomotor activity in zebrafish...

We developed a novel, rapid and cost-effective Zebrafish xenograft model of hepatocellular carcinoma (HCC) for drug screening in the disease. Following injection into the yolk sack of Zebrafish larvae of the human HCC cell line JHH6 stained by a vital dye, tumor mass growth was followed by fluorescence microscopy and by human Ki67 quantification. Tumor induced neo-angiogenesis was evaluated by alkaline phosphatase staining of the vessels, by using the Tg(fli1:EGFP)y(1) strain of Zebrafish and by the quantification of the zebrafish vascular endothelial growth factor and of its receptor...

BACKGROUND: Antipsychotics are essential for the treatment of schizophrenia. However, due to side effects, both continuity of treatment and patients' general health can be jeopardized. Some of these drugs, especially clozapine, have a class of side effects attributed to their antimuscarinic properties, such as dysmotility, a condition in which muscles of the digestive system become impaired. Dysmotility may also alter the speed, strength or coordination of the digestive organs, causing distention, disturbing gastrointestinal transit, leading to symptoms such as bloating, nausea, vomiting, and even malnutrition...

Amyloid peptide precursor (APP) as the precursor protein of peptide beta-amyloid (β-amyloid, Aβ), which is thought to play a central role in the pathogenesis of Alzheimer's disease (AD), also has an important effect on the development and progression of AD. Through knocking-in APP gene in animals, numerous transgenic AD models have been set up for the investigation of the mechanisms behind AD pathogenesis and the screening of anti-AD drugs. However, there are some limitations to these models and here is a need for such an AD model that is economic as well as has satisfactory genetic homology with human...

INTRODUCTION: Zebrafish have been used as a model to access drug-induced hepatotoxicity. However, individual differences occur in the liver development of zebrafish. METHODS: We used a transgenic line of zebrafish that expressed enhanced green fluorescent protein (EGFP) in the liver and then used a calculation of the liver index area, a potentially new endpoint of hepatotoxicity, to evaluate drug-induced liver injury. To further validate the reliability of the liver area index as a quick evaluation of zebrafish liver function damage, the liver area index level was correlated with hepatic transaminase activities using the Pearson correlation coefficient and confirmed by histopathology...

Zebrafish are widely used as model organism. Their suitability for endocrine studies, drug screening and toxicity assessements depends on the extent of conservation of specific genes and biochemical pathways between zebrafish and human. Glucocorticoids consist of inactive 11-keto (cortisone, 11-dehydrocorticosterone) and active 11β-hydroxyl forms (cortisol, corticosterone). In mammals, two 11β-hydroxysteroid dehydrogenases (11β-HSD1, 11β-HSD2) interconvert active and inactive glucocorticoids, allowing tissue-specific regulation of glucocorticoid action...

Zebrafish (Danio rerio) are rapidly becoming a popular model organism in translational and cognitive neuroscience research. Both larval and adult zebrafish continue to increase our understanding of cognitive mechanisms and their genetic and pharmacological modulation. Here, we discuss the developing utility of zebrafish in understanding cognitive phenotypes and their deficits, relevant to a wide range human brain disorders. We also discuss the potential of zebrafish models for high-throughput genetic mutant and small molecule screening (e...

Tiletamine is a non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist chemically related to ketamine and phencyclidine. A common veterinary anesthetic drug, tiletamine is currently a Schedule III controlled substance in USA. This compound exerts sedative effects in humans and animals, also having an abuse potential, toxicity and dissociative hallucinogenic properties clinically. However, the neurotropic profile of tiletamine remains poorly understood, necessitating novel models and in-vivo screens, including non-mammalian species...

The easy-to-use in vivo model, zebrafish larva, is being increasingly used to screen chemical-induced hepatotoxicity, with a good predictivity for various mechanisms of liver injury. However, nothing is known about its applicability in exploring the mechanism called membrane remodeling, depicted as changes in membrane fluidity or lipid raft properties. The aim of this study was, therefore, to substantiate the zebrafish larva as a suitable in vivo model in this context. Ethanol was chosen as a prototype toxicant because it is largely described, both in hepatocyte cultures and in rodents, as capable of inducing a membrane remodeling leading to hepatocyte death and liver injury...

Several drugs, including aminoglycosides and platinum-based chemotherapy agents, are well known for their ototoxic properties. However, FDA-approved drugs are not routinely tested for ototoxicity, so their potential to affect hearing often goes unrecognized. This issue is further compounded for natural products, where there is a lack of FDA oversight and the manufacturer is solely responsible for ensuring the safety of their products. Natural products such as herbal supplements are easily accessible and commonly used in the practice of traditional eastern and alternative medicine...

Patient-derived specimens are an invaluable resource to investigate tumor biology. However, in vivo studies on primary cultures are often limited by the small amount of material available, while conventional in vitro systems might alter the features and behavior that characterize cancer cells. We present our data obtained on primary dedifferentiated liposarcoma cells cultured in a 3D scaffold-based system and injected into a zebrafish model. Primary cells were characterized in vitro for their morphological features, sensitivity to drugs and biomarker expression, and in vivo for their engraftment and invasiveness abilities...

The development of new angiogenic inhibitors highlights a need for robust screening assays that adequately capture the complexity of vessel formation, and allow for the quantitative evaluation of the teratogenicity of new anti-angiogenic agents. This review discusses the use of screening assays in vertebrate embryos, specifically focusing upon chicken and zebrafish embryos, for the detection of anti-angiogenic agents.

By performing two high-content small molecule screens on DSS- and TNBS-induced zebrafish enterocolitis models of inflammatory bowel disease, we have identified novel anti-inflammatory drugs from the John Hopkins Clinical Compound Library that suppress neutrophilic inflammation. Live imaging of neutrophil distribution was used to assess the level of acute inflammation and concurrently screen for off-target drug effects. Supporting the validity of our screening strategy, most of the anti-inflammatory drug hits were known antibiotics or anti-inflammatory agents...
