    mRNA Extraction from Gill Tissue for RNA-sequencing
    Authors:  Jukka-Pekka Verta and Felicity Jones, date: 03/05/2020, view: 286, Q&A: 0
    [Abstract] Adaptation is thought to proceed in part through spatial and temporal changes in gene expression. Fish species such as the threespine stickleback are powerful vertebrate models to study the genetic architecture of adaptive changes in gene expression since divergent adaptation to different environments is common, they are abundant and easy to study ...
    Zebrafish Bacterial Infection Assay to Study Host-Pathogen Interactions
    Authors:  Faiza Basheer, Clifford Liongue and Alister C Ward, date: 03/05/2020, view: 255, Q&A: 0
    [Abstract] The study of host-pathogen interactions has improved our understanding of both pathogenesis and the response of the host to infection, including both innate and adaptive responses. Neutrophils and macrophages represent the first line of innate host defense against any infection. The zebrafish is an ideal model to study the response of these cells ...
    Retina Injury and Retina Tissue Preparation to Study Regeneration in Zebrafish
    Authors:  Poonam Sharma and Rajesh Ramachandran, date: 12/20/2019, view: 559, Q&A: 0
    [Abstract] Unlike mammals, primitive vertebrates have immense capability to regenerate almost all of their organs including the central nervous system. Among primitive organisms, zebrafish have been extensively used as a model system for regeneration studies. The retina is a part of the central nervous system and mammals lack the potential to repair any ...
    Looking through Brains with Fast Passive CLARITY: Zebrafish, Rodents, Non-human Primates and Humans
    Authors:  Farzad Mortazavi, Alexander J. Stankiewicz and Irina V. Zhdanova, date: 08/05/2019, view: 1751, Q&A: 0
    [Abstract] Recently developed CLARITY (Clear Lipid-exchanged Acrylamide-hybridized Rigid Imaging/Immunostaining/In situ-hybridization-compatible Tis-sue-hYdrogel) technique renders the tissue transparent by removing lipids in the tissue, while preserving and stabilizing the cellular and subcellular structures. This provides effective penetration of diverse ...
    A Standardized Tank Design for the Light Dark Task in Zebrafish
    Authors:  Amanda Facciol, Steven Tran and Robert Gerlai, date: 07/20/2019, view: 1105, Q&A: 0
    [Abstract] The light dark paradigm is a common behavioral test used to screen a variety of pharmacological agents, including anxiogenics and anxiolytics. Although most often used in rodents, the light dark task has recently been adapted for use in zebrafish. However, a number of inconsistent findings have been reported for this species. Some have found ...
    Quantification of Cutaneous Ionocytes in Small Aquatic Organisms
    Authors:  Garfield T. Kwan, Shane H. Finnerty, Nicholas C. Wegner and Martin Tresguerres, date: 05/05/2019, view: 1312, Q&A: 0
    [Abstract] Aquatic organisms have specialized cells called ionocytes that regulate the ionic composition, osmolarity, and acid/base status of internal fluids. In small aquatic organisms such as fishes in their early life stages, ionocytes are typically found on the cutaneous surface and their abundance can change to help cope with various metabolic and ...
    Detection of mRNA by Whole Mount in situ Hybridization and DNA Extraction for Genotyping of Zebrafish Embryos
    Authors:  Rachna Narayanan and Andrew C. Oates, date: 03/20/2019, view: 3931, Q&A: 0
    [Abstract] In situ hybridization is used to visualize the spatial distribution of gene transcripts in tissues and in embryos, providing important information about disease and development. Current methods involve the use of complementary riboprobes incorporating non-radioactive labels that can be detected by immunohistochemistry and coupled to ...
    Notochord Injury Assays that Stimulate Transcriptional Responses in Zebrafish Larvae
    [Abstract] Zebrafish have become an increasingly important model organism in the field of wound healing and regenerative medicine, due to their high regenerative capacity coupled with high-resolution imaging in living animals. In a recent study, we described multiple physical and chemical methods to induce notochord injury that led to highly specific ...
    Mosaic Labeling and 3-Dimensional Morphological Analysis of Single Cells in the Zebrafish Left-right Organizer
    Authors:  Agnik Dasgupta, Andrew E. Jacob and Jeffrey D. Amack, date: 11/20/2018, view: 2202, Q&A: 0
    [Abstract] A transient epithelial structure called the left-right organizer (LRO) establishes left-right asymmetry in vertebrate embryos. Developmental defects that alter LRO formation result in left-right patterning errors that often lead to congenital heart malformations. However, little is known about mechanisms that regulate individual cell behaviors ...
    Microplastic Extraction from Marine Vertebrate Digestive Tracts, Regurgitates and Scats: A Protocol for Researchers from All Experience Levels
    Authors:  Amy L. Lusher and Gema Hernandez-Milian, date: 11/20/2018, view: 4693, Q&A: 0
    [Abstract] It is essential to provide a protocol for the separation and identification of microplastics in marine vertebrates (mammals, birds, turtles and fish) that is easy to follow and adaptable depending on research infrastructure. Digesting organic material is an effective way to analyze samples for microplastics. Presented here is an optimized protocol ...
