    Identification of Intrinsic RNA Binding Specificity of Purified Proteins by in vitro RNA Immunoprecipitation (vitRIP)
    Authors:  Marisa Müller, Tamas Schauer and Peter B. Becker, date: 03/05/2021, view: 915, Q&A: 0
    [Abstract]

    RNA-protein interactions are often mediated by dedicated canonical RNA binding domains. However, interactions through non-canonical domains with unknown specificity are increasingly observed, raising the question how RNA targets are recognized. Knowledge of the intrinsic RNA binding specificity contributes to the understanding of target

    Extraction and Quantification of Sphingolipids from Hemiptera Insects by Ultra-Performance Liquid Chromatography Coupled to Tandem Mass Spectrometry
    Authors:  Ni Wang, Xiaoxiao Shi, Chao Zhang, Wenwu Zhou and Zeng-Rong Zhu, date: 02/20/2021, view: 782, Q&A: 0
    [Abstract]

    Sphingolipids are major structural components of endomembranes and have also been described as an intracellular second messenger involved in various biological functions in all eukaryotes and a few prokaryotes. Ceramides (Cer), the central molecules of sphingolipids, have been depicted in cell growth arrest, cell differentiation, and apoptosis.

    Molecular and Phenotypic Characterization Following RNAi Mediated Knockdown in Drosophila
    Authors:  Saurabh Jayesh Kumar Mehta, Pradyumna A. Joshi and Ram Kumar Mishra, date: 02/20/2021, view: 891, Q&A: 0
    [Abstract]

    Loss of function studies shed significant light on the involvement of a gene or gene product in different cellular processes. Short hairpin RNA (shRNA) mediated RNA interference (RNAi) is a classical yet straightforward technique frequently used to knock down a gene for assessing its function. Similar perturbations in gene expression can be

    Immuno-electrophysiology on Neuromuscular Junctions of Drosophila Third Instar Larva
    Authors:  Raffaella Klima, Giulia Romano, Monsurat Gbadamosi, Aram Megighian and Fabian Feiguin, date: 02/05/2021, view: 352, Q&A: 0
    [Abstract]

    Alterations in synaptic transmission are critical early events in neuromuscular disorders. However, reliable methodologies to analyze the functional organization of the neuromuscular synapses are still needed. This manuscript provides a detailed protocol to analyze the molecular assembly of the neuromuscular synapses through

    Ecdysone Quantification from Whole Body Samples of Drosophila melanogaster Larvae
    Authors:  Takashi Koyama and Christen K. Mirth, date: 02/05/2021, view: 454, Q&A: 0
    [Abstract]

    Steroid hormones strictly control the timing of sexual maturation and final body size both in vertebrates and invertebrates. In insects, the steroid hormone ecdysone controls the timing of the molts between larval instars as well as the transition to metamorphosis. Growth during the final instar accounts for over 80% of the increase in final mass

    Evaluation of Toxicity with Brine Shrimp Assay
    Authors:  Christina N. Banti and Sotiris K. Hadjikakou, date: 01/20/2021, view: 937, Q&A: 0
    [Abstract]

    The in vivo toxicity of new metallodrugs either as Small Bioactive Molecules (SBAMs) or Conjugates of Metals with Drugs (CoMeDs) or their hydrogels such as with hydroxyethyl-methacrylate (HEMA) (pHEMA@SBAMs or pHEMA@CoMeDs) are evaluated by the brine shrimp assay. Thus individuals of Artemia salina larvae are incubated in saline solutions with

    Pea Aphid Rearing, Bacterial Infection and Hemocyte Phagocytosis Assay
    Authors:  Li Ma, Lu Liu and Zhiqiang Lu, date: 12/20/2020, view: 697, Q&A: 0
    [Abstract]

    Insects rely on the simple but effective innate immune system to combat infection. Cellular and humoral responses are interconnected and synergistic in insects’ innate immune system. Phagocytosis is one major cellular response. It is difficult to collect clean hemolymph from the small insect like pea aphid. Here, we provide a practicable

    Use of Optogenetic Amyloid-β to Monitor Protein Aggregation in Drosophila melanogaster, Danio rerio and Caenorhabditis elegans
    Authors:  Prameet Kaur, Caroline Kibat, Emelyne Teo, Jan Gruber, Ajay Mathuru and Nicholas S. Tolwinski, date: 12/05/2020, view: 1047, Q&A: 0
    [Abstract]

    Alzheimer’s Disease (AD) has long been associated with accumulation of extracellular amyloid plaques (Aβ) originating from the Amyloid Precursor Protein. Plaques have, however, been discovered in healthy individuals and not all AD brains show plaques, suggesting that extracellular Aβ aggregates may play a smaller role than

    DigiTAG–a RNA Sequencing Approach to Analyze Transcriptomes of Rare Cell Populations in Drosophila melanogaster
    Authors:  Lisa Landskron, Francois Bonnay, Thomas R. Burkard and Jürgen A. Knoblich, date: 11/05/2020, view: 1091, Q&A: 0
    [Abstract]

    Cell-type specific transcriptional programs underlie the development and maintenance of organs. Not only distinct cell types within a tissue, even cells with supposedly identical cell fates show a high degree of transcriptional heterogeneity. Inevitable, low cell numbers are a major hurdle to study transcriptomes of pure cell populations. Here we

    Quantification of Methylglyoxal Levels in Cowpea Leaves in Response to Cowpea Aphid Infestation
    [Abstract] Aphids are a serious pest of crops across the world. Aphids feed by inserting their flexible hypodermal needlelike mouthparts, or stylets, into their host plant tissues. They navigate their way to the phloem where they feed on its sap causing little mechanical damage to the plant. Additionally, while feeding, aphids secrete proteinaceous effectors ...
