    Imaging the Vasculature of Immunodeficient Mice Using Positron Emission Tomography/Computed Tomography (PET/CT) and 18F-fluorodeoxyglucose Labeled Human Erythrocytes
    Authors:  Shaowei Wang and Jung W. Choi, date: 10/05/2019, view: 99, Q&A: 0
    [Abstract] Nuclear blood pool imaging using radiolabeled red blood cells has been used in the clinical setting for the evaluation of a number of medical conditions including gastrointestinal hemorrhage, impaired cardiac contractility, and altered cerebrovascular blood flow. Nuclear blood pool imaging is typically performed using Technetium-99m-labeled (99m ...
    Conjugation of Fab’ Fragments with Fluorescent Dyes for Single-molecule Tracking on Live Cells
    Authors:  I-Ting Teng, Xiangning Bu and Inhee Chung, date: 09/20/2019, view: 222, Q&A: 0
    [Abstract] Our understanding of the regulation and functions of cell-surface proteins has progressed rapidly with the advent of advanced optical imaging techniques. In particular, single-molecule tracking (SMT) using bright fluorophores conjugated to antibodies and wide-field microscopy methods such as total internal reflection fluorescence microscopy have ...
    SIRF: A Single-cell Assay for in situ Protein Interaction with Nascent DNA Replication Forks
    Authors:  Sunetra Roy and Katharina Schlacher, date: 09/20/2019, view: 280, Q&A: 0
    [Abstract] The duplication of DNA is a fundamental process that is required for the transfer of the genetic information from parent to daughter cells. Aberrant DNA replication processes are associated with diverse disease phenotypes, including developmental defects, ageing disorders, blood disorders such as Fanconi Anemia, increased inflammation and cancer. ...
    A Cell Culture Model that Mimics Physiological Tissue Oxygenation Using Oxygen-permeable Membranes
    Authors:  Chloe-Anne Martinez, Peter A. Cistulli and Kristina M. Cook, date: 09/20/2019, view: 275, Q&A: 0
    [Abstract] Dissolved oxygen and its availability to cells in culture is an overlooked variable which can have significant consequences on experimental research outcomes, including reproducibility. Oxygen sensing pathways play key roles in cell growth and behavior and pericellular oxygen levels should be controlled when establishing in vitro models. ...
    A Robust, One-step FRET Assay for Human Heparanase
    Authors:  Jyothi C. Sistla and Umesh R. Desai, date: 09/05/2019, view: 281, Q&A: 0
    [Abstract] Heparanase, an endo-β-D-glucuronidase, cleaves cell surface and extracellular matrix heparan sulfate (HS) chains at distinct sites and plays important biological roles including modulation of cell growth and metastasis. Although a number of different types of heparanase assays have been reported to date, most are labor intensive, complex ...
    Three-dimensional Reconstruction and Quantification of Proteins and mRNAs at the Single-cell Level in Cultured Cells
    Authors:  Xueer Jiang, Ingrid Brust-Mascher and Li-En Jao, date: 08/20/2019, view: 639, Q&A: 0
    [Abstract] Gene expression is often regulated by the abundance, localization, and translation of mRNAs in both space and time. Being able to visualize mRNAs and protein products in single cells is critical to understand this regulatory process. The development of single-molecule RNA fluorescence in situ hybridization (smFISH) allows the detection of ...
    Photodynamic Therapy in a 3D Model of Ovarian Cancer
    Authors:  Shubhankar Nath and Kaitlin Moore, date: 08/05/2019, view: 447, Q&A: 0
    [Abstract] Photodynamic therapy (PDT), is a clinically-approved light-based anti-cancer treatment modality in which a photoactivatable photosensitizer is irradiated with an appropriate wavelength of light to generate cytotoxic molecules to kill cancer cells. In this article, we describe an in vitro PDT protocol using a 3-dimensional (3D) model of ...
    Evaluation of Genotoxicity by Micronucleus Assay in vitro and by Allium cepa Test in vivo
    Authors:  Christina N. Banti and Sotiris K. Hadjikakou, date: 07/20/2019, view: 907, Q&A: 0
    [Abstract] The in vitro and in vivo genotoxicity of new metallodrugs either as Small Bioactive Molecules (SBAMs) or Conjugates of Metals with Drugs (CoMeDs) is evaluated by the micronucleus test and the Allium cepa assay, respectively. Fetal lung fibroblast cells (MRC-5), normal human corneal epithelial cells (HCEC) and ...
    Total RNA Isolation from Separately Established Monolayer and Hydrogel Cultures of Human Glioblastoma Cell Line
    Authors:  Manasi P Jogalekar and Elba E Serrano, date: 07/20/2019, view: 886, Q&A: 0
    [Abstract] Astrocytoma is an invasive carcinoma occurring in the nervous system and currently lacks effective treatment options. A deeper understanding of the mechanisms of tumorigenesis and tumor progression is needed in order to develop novel therapeutic strategies. Recent advances in in vitro culture systems have demonstrated that the use of ...
    The Chick Chorioallantoic Membrane (CAM) Assay as a Three-dimensional Model to Study Autophagy in Cancer Cells
    [Abstract] The chick chorioallantoic membrane (CAM) is an extra-embryonic organ and thus well accessible for seeding and harvesting 3D cell cultures. Samples from CAM assays are suitable for protein and gene expression analysis as well as for immuno-histochemical studies. Here we present the CAM assay as a possible model to study autophagy in different types ...
