    RNA Interference Method for Gene Function Analysis in the Japanese Rhinoceros Beetle Trypoxylus dichotomus
    Authors:  Kazuki Sakura, Shinichi Morita and Teruyuki Niimi, date: 04/20/2022, view: 694, Q&A: 0

    In the Japanese rhinoceros beetle Trypoxylus dichotomus, various candidate genes required for a specific phenotype of interest are listed by next-generation sequencing analysis. Their functions were investigated using RNA interference (RNAi) method,

    Measurement of Contractile Ring Tension Using Two-photon Laser Ablation during Drosophila Cellularization
    Authors:  Swati Sharma and Richa Rikhy, date: 03/20/2022, view: 373, Q&A: 0

    Cytokinesis occurs at the final step of cell division and leads to the separation of daughter cells. It requires assembly and constriction of the actomyosin contractile ring. The phases of assembly and constriction of the contractile ring show an

    Labeling and Tracking Mitochondria with Photoactivation in Drosophila Embryos
    Authors:  Sayali Chowdhary and Richa Rikhy, date: 03/05/2022, view: 1273, Q&A: 0

    Mitochondria are relatively small, fragmented, and abundant in the large embryos of Drosophila, Xenopus and zebrafish. It is essential to study their distribution and dynamics in these embryos to understand the mechanistic role of mitochondrial

    Total Nucleic Acid Extraction from Single Zebrafish Embryos for Genotyping and RNA-seq
    Authors:  Neha Wali, Munise Merteroglu, Richard J. White and Elisabeth M. Busch-Nentwich, date: 01/05/2022, view: 1483, Q&A: 0

    RNA sequencing allows for the quantification of the transcriptome of embryos to investigate transcriptional responses to various perturbations (e.g., mutations, infections, drug treatments). Previous protocols either lack the option to genotype

    Whole-mount Immunohistochemistry to Visualize Mouse Embryonic Dermal Lymphatic Vasculature
    Authors:  Xin Geng and R. Sathish Srinivasan, date: 10/20/2021, view: 951, Q&A: 0

    Lymphatic vessels are abundant in the skin where they regulate interstitial fluid uptake and immune surveillance. Defects in dermal lymphatic vessels, such as fewer vessels and abnormal lymphatic vessel coverage with mural cells, are frequently

    Phalloidin Staining of Actin Filaments for Visualization of Muscle Fibers in Caenorhabditis elegans
    Authors:  Mario Romani and Johan Auwerx, date: 10/05/2021, view: 1917, Q&A: 0

    Advances in C. elegans research have allowed scientists to recapitulate different human disorders, from neurodegenerative diseases to muscle dysfunction, in these nematodes. Concomitantly, the interest in visualizing organs affected by these

    En masse DNA Electroporation for in vivo Transcriptional Assay in Ascidian Embryos
    Author:  Sébastien Darras, date: 09/20/2021, view: 1470, Q&A: 0

    Ascidian embryos are powerful models for functional genomics, in particular, due to the ease of generating a large number of transgenic embryos by electroporation. In addition, the small size of their genome makes them an attractive model for

    Inter-species Transplantation of Blastocysts between Medaka and Zebrafish
    Authors:  Jana F. Fuhrmann, Jasmin Onistschenko and Lázaro Centanin, date: 09/20/2021, view: 1252, Q&A: 0

    Transplantation of blastocysts from a donor to a host blastula constitutes a powerful experimental tool to tackle major developmental biology questions. The technique is widely implemented in diverse biological models including teleost fish, where

    Direct-TRI: High-throughput RNA-extracting Method for all Stages of Zebrafish Development
    Authors:  Kota Ujibe, Kanako Nishimura, Makoto Kashima and Hiromi Hirata, date: 09/05/2021, view: 1585, Q&A: 0

    Recent popularization of next-generation sequencing enables conducting easy transcriptome analysis. Nevertheless, substantial RNA isolation work prior to RNA sequencing, as well as the high cost involved, still makes the routine use of large-scale

    A Genetically Engineered Mouse Model of Venous Anomaly and Retinal Angioma-like Vascular Malformation
    Authors:  Xudong Cao, Beibei Xu, Xiao Li, Taotao Li and Yulong He, date: 08/05/2021, view: 1634, Q&A: 0

    Characterization of key regulators in vein development will advance our understanding of mechanisms underlying venous anomalies and provide therapeutic targets for the treatment of vascular malformations. Here, we provide a detailed protocol for the
