Biochemistry Measuring and Interpreting Oxygen Consumption Rates in Whole Fly Head Segments Louisa Jutta Dietz1, Anuroop Venkateswaran Venkatasubramani1, Annika Müller-Eigner2, Martin Hrabe de Angelis3,4,5, Axel Imhof1, Lore Becker3, Shahaf Peleg2,6,7 1Munich Center of Integrated Protein Science and Biomedical Center, Ludwig-Maximilians University of Munich, 2Laboratory for Metabolism and Epigenetics in Aging, Leibniz Institute for Farm Animal Biology (FBN), 3German Mouse Clinic, Helmholtz Zentrum Munich, German Research Center for Environment and Health (GmbH), 4German Center for Diabetes Research (DZD), 5Chair of Experimental Genetics, School of Life Science Weihenstephan, Technische Universität München, 6Laboratory for Metabolism and Epigenetics in Brain Aging, Institute of Neuroregeneration & Neurorehabilitation of Qingdao University, 7Molecular Biology Division, Biomedical Center, Faculty of Medicine, Ludwig-Maximilians University of Munich Measuring alterations in metabolic rates is central to understanding the progression of various diseases and aging. Here, we present a novel technique to measure whole head oxygen consumption that more closely resembles the physiological state and may aid in revealing novel drugs that modify mitochondrial activity. Biochemistry Plate-based Large-scale Cultivation of Caenorhabditis elegans: Sample Preparation for the Study of Metabolic Alterations in Diabetes Katharina Kohl1, Thomas Fleming2,3, Kübra Acunman1, Hans-Peter Hammes1,4, Michael Morcos*1, Andrea Schlotterer*1 15th Medical Department, Medical Faculty Mannheim, Heidelberg University, 2Department of Internal Medicine, Heidelberg University, 3German Center for Diabetes Research (DZD), 4European Center for Angioscience, Medical Faculty Mannheim, Heidelberg University This protocol describes a method for the large-scale cultivation of Caenorhabditis elegans on solid media. As an alternative to liquid culture, this protocol allows obtaining parameters of different scales under plate-based cultivation. This increases the comparability of results by omitting the morphological and metabolic differences between liquid and solid media culture.
