    Tyramide Signal-Amplified Immunofluorescence of MYCN and MYC in Human Tissue Specimens and Cell Line Cultures
    Authors:  Johanna M. Schafer and Jennifer A. Pietenpol, date: 07/05/2020, view: 110, Q&A: 0
    MYC family members, MYC, MYCN, and MYCL, are oncogenic transcription factors that regulate the expression of genes involved in normal development, cell growth, proliferation, metabolism, and survival. While MYC is amplified and/or overexpressed ...
    Generation and Testing of Fluorescent Adaptable Simple Theranostic (FAST) Proteins
    This protocol provides a step-by-step method to create recombinant fluorescent fusion proteins that can be secreted from mammalian cell lines. This builds on many other recombinant protein and fluorescent protein techniques, but is among the first ...
    NMR waterLOGSY as An Assay in Drug Development Programmes for Detecting Protein-Ligand Interactions–NMR waterLOGSY
    Authors:  Carole J. R. Bataille, Terence H. Rabbitts and Timothy D. W. Claridge, date: 07/05/2020, view: 174, Q&A: 0
    In drug development programmes, multiple assays are needed for the determination of protein-compound interactions and evaluation of potential use in assays with protein-protein interactions. In this protocol we describe the waterLOGSY NMR method for ...
    Isolation of Lipid Rafts from Cultured Mammalian Cells and Their Lipidomics Analysis
    Authors:  Nigora Mukhamedova, Kevin Huynh, Hann Low, Peter J. Meikle and Dmitri Sviridov, date: 07/05/2020, view: 112, Q&A: 0
    Lipid rafts are distinct liquid-ordered domains of plasma membranes of most eukaryotic cells providing platform for signaling pathways. Lipid composition of rafts is critical for their structural integrity and for regulation of signaling pathways ...
    Tyramide Signal-Amplified Immunofluorescence of MYCN and MYC in Human Tissue Specimens and Cell Line Cultures
    Authors:  Johanna M. Schafer and Jennifer A. Pietenpol, date: 07/05/2020, view: 110, Q&A: 0
    [Abstract] MYC family members, MYC, MYCN, and MYCL, are oncogenic transcription factors that regulate the expression of genes involved in normal development, cell growth, proliferation, metabolism, and survival. While MYC is amplified and/or overexpressed across a variety of tissue types, MYCN is often overexpressed in tumors of the nervous system ...
    Generation and Testing of Fluorescent Adaptable Simple Theranostic (FAST) Proteins
    [Abstract] This protocol provides a step-by-step method to create recombinant fluorescent fusion proteins that can be secreted from mammalian cell lines. This builds on many other recombinant protein and fluorescent protein techniques, but is among the first to harness fluorescent fusion proteins secreted directly into cell culture supernatant. This opens ...
    NMR waterLOGSY as An Assay in Drug Development Programmes for Detecting Protein-Ligand Interactions–NMR waterLOGSY
    Authors:  Carole J. R. Bataille, Terence H. Rabbitts and Timothy D. W. Claridge, date: 07/05/2020, view: 174, Q&A: 0
    [Abstract] In drug development programmes, multiple assays are needed for the determination of protein-compound interactions and evaluation of potential use in assays with protein-protein interactions. In this protocol we describe the waterLOGSY NMR method for confirming protein-ligand binding events.
    Isolation of Lipid Rafts from Cultured Mammalian Cells and Their Lipidomics Analysis
    Authors:  Nigora Mukhamedova, Kevin Huynh, Hann Low, Peter J. Meikle and Dmitri Sviridov, date: 07/05/2020, view: 112, Q&A: 0
    [Abstract] Lipid rafts are distinct liquid-ordered domains of plasma membranes of most eukaryotic cells providing platform for signaling pathways. Lipid composition of rafts is critical for their structural integrity and for regulation of signaling pathways originating from rafts. Here we provide a protocol to isolate lipid rafts from cultured human and ...
    Modeling NOTCH1 driven T-cell Acute Lymphoblastic Leukemia in Mice
    Authors:  Agnieszka A. Wendorff and Adolfo A. Ferrando, date: 05/20/2020, view: 690, Q&A: 0
    [Abstract] T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy that arises from transformation of T-cell primed hematopoietic progenitors. Although T-ALL is a heterogenous and molecularly complex disease, more than 65% of T-ALL patients carry activating mutations in the NOTCH1 gene. The majority of T-ALL–associated ...
    Isolation of Tumor Cells Based on Their Distance from Blood Vessels
    Authors:  Saran Kumar, Husni Sharife, Tirzah Kreisel, Libat Bar-Lev, Myriam Grunewald and Eli Keshet, date: 05/20/2020, view: 824, Q&A: 0
    [Abstract] Differential exposure of tumor cells to microenvironmental cues greatly impacts cell phenotypes, raising a need for position based sorting of tumor cells amenable to multiple OMICs and functional analyses. One such key determinant of tumor heterogeneity in solid tumors is its vasculature. Proximity to blood vessels (BVs) profoundly affects tumor ...
    Evaluation of the Efficiency of Genome Editing Tools by a Frameshift Fluorescence Protein Reporter
    Authors:  Balaji T. Moorthy, Akhilesh Kumar, Lauren X. Lotenfoe and Fangliang Zhang, date: 05/20/2020, view: 797, Q&A: 0
    [Abstract] In the last decade, genome editing has been the center of attention as a novel tool for mechanistic investigations and for potential clinical applications. Various genome editing tools like meganucleases, zinc finger nucleases (ZFNs), transcription activator-like effector-based nucleases (TALEN), and the clustered regularly interspaced short ...
    Colorimetric RhoB GTPase Activity Assay
    Authors:  Kossay Zaoui and Stephanie Duhamel, date: 05/05/2020, view: 1086, Q&A: 0
    [Abstract] The Ras homologous protein (Rho) GTPase subfamily, including RhoA, RhoB, and RhoC are small molecules (~21 kDa) that act as molecular switches in a wide range of signaling pathways to orchestrate biological processes associated with both physiological and tumorigenic cellular states. The Rho GTPases are crucial regulators of actin cytoskeleton ...
    Single Cell Migration Assay Using Human Breast Cancer MDA-MB-231 Cell Line
    Authors:  David M. Gau and Partha Roy, date: 04/20/2020, view: 1213, Q&A: 0
    [Abstract] Cell migration is a fundamental cellular process that plays a crucial role in many physioglogical and pathological processes such as wound healing or cancer metastasis. Many assays have been developed to examine cell migration, such as the wound healing or scratch assay, Boyden Chamber or transwell assay, and the method we will describe here, ...
    Measurement of Protein-Protein Interactions through Microscale Thermophoresis (MST)
    Authors:  Magnez Romain, Bryan Thiroux, Morgane Tardy, Bruno Quesnel and Xavier Thuru, date: 04/05/2020, view: 815, Q&A: 0
    [Abstract] The binding interactions of PD-1 and PD-L1 have been studied by surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) over the past few years, but these investigations resulted in controversy regarding the values of the dissociation constant (Kd) (Freeman et al., 2000). MST is a powerful new method for the ...
