High-throughput Analysis of Locomotor Behavior in the Drosophila Island Assay Ilse Eidhof*1, Michaela Fenckova*1, Dei M. Elurbe2, Bart van de Warrenburg3, Anna Castells Nobau*1, Annette Schenck*1 1Department of Human Genetics, Donders Institute for Brain, Cognition and Behaviour, Radboud University Medical Center, 2Centre for Molecular and Biomolecular Informatics, Radboud Institute for Molecular Life Sciences, Radboud University Medical Center, 3Department of Neurology, Donders Institute for Brain, Cognition and Behaviour, Radboud University Medical Center The island assay is a relatively new, cost-effective assay that can be used to evaluate the basic locomotor behavior of Drosophila melanogaster. This manuscript describes algorithms for automatic data processing and objective quantification of island assay data, making this assay a sensitive, high-throughput readout for large genetic or pharmacological screens.
Cellular Redox Profiling Using High-content Microscopy Tom Sieprath1,2, Tobias Corne1,2, Joke Robijns1, Werner J. H. Koopman3, Winnok H. De Vos1,2 1Laboratory of Cell Biology and Histology, Department of Veterinary Sciences, University of Antwerp, 2Cell Systems and Imaging Research Group (CSI), Department of Molecular Biotechnology, Ghent University, 3Department of Biochemistry , Radboud Institute for Molecular Life Sciences, Radboud University Medical Center This paper presents a high-content microscopy workflow for simultaneous quantification of intracellular ROS levels, as well as mitochondrial membrane potential and morphology – jointly referred to as mitochondrial morphofunction – in living adherent cells using the cell-permeant fluorescent reporter molecules 5-(and-6)-chloromethyl-2',7'-dichlorodihydrofluorescein diacetate, acetyl ester (CM-H2DCFDA) and tetramethylrhodamine methylester (TMRM).
Using Bioluminescent Imaging to Investigate Synergism Between Streptococcus pneumoniae and Influenza A Virus in Infant Mice Kirsty R. Short1, Dimitri A. Diavatopoulos2, Patrick C. Reading1, Lorena E. Brown1, Kelly L. Rogers3, Richard A. Strugnell1, Odilia L.C. Wijburg1 1Department of Microbiology and Immunology, University of Melbourne, 2Laboratory of Pediatric Infectious Diseases, Radboud University Nijmegen Medical Centre, 3The Centre for Dynamic Imaging, The Walter and Eliza Hall Institute for Medical Research A concurrent infection with influenza A virus is one of the factors implicated in the induction of invasive pneumococcal disease during asymptomatic Streptococcus pneumoniae carriage. Here we describe a mixed infection method using infant mice to investigate the synergism between these two respiratory pathogens.
