UC Davis - Tissue TG & TC Protocol

Peter Havel DOI:10.17504/protocols.io.62thgen Mouse Metabolic Phenotyping Centers Summary: The lipid extraction method is based on work by Folch 1957. Tissue is homogenized and put into a 2:1 chloroform and methanol mix. The mix is separated into two phases by adding a salt solution. The upper phase contains any non-lipid substances and the lower phase contains the chloroform with the lipids. The upper phase is removed and a sample is taken from the bottom phase and evaporated. The sample is reconstituted with 2-propanol with a volume to bring it to the desired concentration to assay. Triglycerides are enzymatically hydrolyzed by lipase to free fatty acids and glycerol. The glycerol is phosphorylated by adenosine triphosphate (ATP) with glycerol kinase (GK) to produce glycerol-3- phosphate and adenosine diphosphate. Glycerol-3-phosphate is oxidized by dihydroxyacetone phosphate (DAP) by glycerolphosphate oxidase producing hydrogen peroxide (H²O²). In a Trinder5 type color reaction catalyzed by peroxidase, the H²O² reacts with 4-aminoantipyrine (4-AAP) and 3,5-dichloro-2- hydroxybenzene sulfonate (DHBS) to produce a red colored dye. The absorbance of this dye is proportional to the concentration of triglycerides present in the sample. Cholesterol esters are enzymatically hydrolysed by cholesterol esterase to cholesterol and free fatty acids. Free cholesterol, including that originally present, is then oxidized by cholesterol oxidase to cholest-4-en-3- one and hydrogen peroxide. The hydrogen peroxide combines with HBA and 4-aminoantipyrine to form a chromophore (quinoneimine dye) which may be quantitated at 500-550nm.

Pre-validation survey for the elimination of trachoma and evaluation of the effectiveness of the trachoma surveillance strategy in Ghana
 
Resource Report

Oscar Debrah, Ernest Mensah, Laura Senyonjo, Dziedzom K. de Souza, Tei E. Hervie, David Agyemang, Didier Bakajika, Benjamin Marfo, Felix Ahorsu, Seth Wanye, Joseph Koroma, Agatha Aboe, Nana-Kwadwo Biritwum DOI:10.17504/protocols.io.h9db926 Background: In order to achieve elimination of blinding trachoma, a country needs to demonstrate that the elimination prevalence thresholds have been surpassed and then sustained for a three year period. Ghana achieved the thresholds in 2008, and since 2011 have been implementing their trachoma surveillance strategy, which includes community and school screening for signs of follicular trachoma and trichiasis, in each trachoma-endemic district. In 2015, the country plans to conduct a number of district level population based survey to verify elimination of blinding trachoma. This decision is currently made based on prevalence of clinical evaluation of “trachomatous trichiasis” and “trachomatous inflammation – follicular” (TF), the second of which has been shown to be a problematic indicator in low prevalence settings. Further evidence is required to determine the optimal surveillance strategy and indicators for trachoma.Objectives: This study will determine if Ghana has sustained the elimination prevalence thresholds. Additionally, the study will review the trachoma surveillance strategy employed in Ghana and if it was able to identify any potential resurgence of infection. It will also assess the relationships between the prevalence of the clinical sign TF, compared to prevalence of infection and antibody levels, after completion of what most observers believe to have been a successful programme. This will help to determine whether it may be appropriate to consider one or more alternative indicators for validating elimination of blinding trachoma. Surveillance for other infections (including yaws and other NTDs) will also be integrated into the pre-validation trachoma survey.Methods: The standard World Health Organization (WHO)-recommended population-based prevalence survey will be conducted in areas already scheduled to conduct validation surveys in 2015, but with the addition of eye swabbing to test for infection and finger pricking to collect bloodspots for antibody testing. Villages identified with a TF prevalence ≥5%, either retrospectively, during the on-going surveillance or during the district level survey (index village), will result in focal screening of children in neighbouring villages (and the ‘index’ village), including a clinical assessment and tests for trachoma infection and antibody levels. Surveillance for additional infections will also be included through antibody testing using the same sera collected for trachoma. Finally, document analysis and qualitative methodologies will be employed to review the operationalization of the trachoma surveillance system in Ghana.Impact: Results from this study will provide the Ghana Health Service with evidence, as to whether the country has sustained their elimination targets for trachoma. It will also inform the WHO-led Alliance for the Global Elimination of Trachoma by 2020 (GET2020) on the appropriateness of alternative indicators and surveillance methodologies for verification of blinding trachoma. 1.

Susan A. Kimmance and Corina P. D. Brussaard DOI:10.17504/protocols.io.dpf5jm VERVE Net The modified dilution assay aims to partition phytoplankton mortality into virus- versus grazing-induced fractions and has previously been applied to several different environments to determine viral lysis rates of natural phytoplankton. The method involves creating a gradient of both grazing and viral lysis by dilution with different proportions of grazer- and virus-free filtrate, and assessing the subsequent impact on phytoplankton growth rates.Kimmance, S.

Many factors including age, obesity, estrogen and diet, are associated with bone mass loss. Mice studies suggested that the gut microbiome might affect the bone mass by regulating the immune system, however there has been little evidence from human studies. Bone loss increases after menopause. Therefore, we have recruited 361 Chinese post-menopausal women to collect their fecal samples and metadata to conduct metagenome-wide association study (MWAS) to investigate the influence of the gut microbiome on bone health. Gut microbiome sequencing data were produced using BGISEQ500 sequencing, Bone mineral density (BMD) was calculated using Hologic dual energy X-ray machine, body mass index (BMI) and age were also recorded.This collected data allows exploration of the gut microbial diversity and their links to bone mass loss, as well as microbial markers for bone mineral density. In addition, these data are potentially useful in studying the role the gut microbiota might play in bone mass loss and in exploring the bone mass loss process.

Sam Li DOI:10.17504/protocols.io.baaqiadw BioLegend Anti-Neu5Gc may be used for staining cells prior to analysis by Flow Cytometry. This kit contains all the essential components needed to identify Neu5Gc on the surface of cells by flow cytometry.Use of the blocking agent (Neu5Gc Assay Blocking Solution) provided in the kit is essential, as commonly used blocking agents invariably contain serum, or serum components, that can either inhibit detection or introduce Neu5Gc contamination.Tissue culture-grown CHO-K1 cells can be used as a positive control, and human peripheral blood mononuclear cells serve as a negative control. Adherent tissue culture-grown cells should be released from the culture flasks by using 5-10mM EDTA for 10 minutes at room temperature. Other non-enzymatic methods, such as Accutase®, may be used. Immediately wash cells in blocking buffer that contains a lower concentration of EDTA, and resuspend cells in blocking buffer to determine cell numbers and viability.It is assumed that the user is familiar with the general principles and practices of Flow Cytometry.

Electrophoretic Mobility Shift Assays using Infrared-Fluorescent DNA Probes
 
Resource Report

Michael Van Dyke, James Cox DOI:10.17504/protocols.io.mbdc2i6 Protein-DNA binding interactions are critical in several biological processes, especially the regulation of gene expression at the level of transcription initiation. An important technique for studying these interactions is the electrophoretic mobility shift assay (EMSA), whereby protein-DNA complexes are resolved on the basis of their mass:charge ratio using native polyacrylamide gel electrophoresis (nPAGE). Here we describe EMSA using PCR-generated, near infrared-fluorescent DNA probes, and IR fluorescence imaging to qualitatively and quantitatively study the interaction of transcriptional regulatory proteins from thermophilic organisms with different DNAs. Direct imaging of IR fluorophore-labeled DNA probes is advantageous because it provides high sensitivity (subnanomolar) without the need for intermediate staining steps or costly and problematic radiolabeled probes, thereby providing a more affordable and sensitive option to image protein-DNA on polyacrylamide gels by techniques such as EMSA.
