Case - Glycerol and Glucose Assays by GC-mass spectrometry Resource Report Resource Website |
Henri Brunengraber | 10.17504/protocols.io.ydkfs4w | Mouse Metabolic Phenotyping Centers, Metabolomics Protocols & Workflows | Total glycerol is determined by first hydrolyzing glycerides (in plasma or tissues) in 1 N KOHethanol + heat and then the hydrolysate extracted following acidification ~pH 1.0. A two phase extract is created using chloroform. The aqueous phase contains the total glycerol and the organic phase contains total fatty acids. An aliquot of aqueous phase in dried down by nitrogen gas and the concentration and/or 2H-labelled glycerol is then determined by GC-MS following conversion of glycerol to its triacetate derivative. Glucose assay involves extraction of glucose from blood, plasma or tissues and the concentration and/or 2H/13C-labelled glucose is also determined by GC-MS following conversion to its pentaacetate derivative. Since the derivatizing methods are the same for glucose as glycerol, the can be assayed from a single sample preparation under the same GC-MS conditions and single run-time.References: 1.

UC Davis - Meal Pattern Analysis Resource Report Resource Website |
Trina Knotts | 10.17504/protocols.io.yrwfv7e | Mouse Metabolic Phenotyping Centers | Behaviorally, meals are defined as periods of intense feeding and drinking separated by periods of activity, grooming, and rest. A “meal” is the primary data unit for characterizing food intake behavior. Changes in the patterning of meals (number, size or duration) may affect food intake and energy balance indirectly. "Meal", in our SOP, is defined by a minimum food intake of 0.02g and at least 10 min between food bout events. Detailed analysis of food intake behavior includes an assessment of average meal duration, average meal size, number of meals, average inter-meal interval (IMI), as well as calculation of satiety ratio. In addition, the diurnal (light cycle/dark cycle) patterns of food intake behavior are also calculated to examine temporal shifts in feeding behavior. Meal pattern and food intake behavior is measured in the Columbus Instruments Oxymax system within a temperature and light controlled cabinet. Animals are acclimated to the facility for at least 1 week. Animals are then acclimated to the CLAMS cages and powdered diet for 48 hours and to the light and temperature-controlled chamber for 24 hours prior to testing. Analyzed data constitutes data collected from 48 hours of continuous measurement (2 light/2 dark cycles). | University of California, Davis | https://mmpc.org/shared/document.aspx?id=285&docType=Protocol | 1 | 2019 | Trina Knotts 2019.

U Michigan - Glomerular Filtration Rate Determination with Minipump Inulin Clearance Resource Report Resource Website |
Jeff Hodgin | 10.17504/protocols.io.x63frgn | Mouse Metabolic Phenotyping Centers | This is the protocol for measuring Glomerular Filtration Rate (GFR) with minipump FITC-inulin clearance in mice. In brief, Alzet micro-osmotic pumps (minipumps, Model 1007D) are filled with 3% FITC-inulin solution. These pumps release FITC-inulin at a rate of 0.5 μl/hr at least seven days. Mouse is temporarily anesthetized and then two mini-pumps are implanted in mouse peritoneal cavity through a tiny midline incision. After surgery, 24-hour urine is collected with metabolic cage and 100 μl of blood from saphenous vein is obtained at the same time. The concentrations of FITC-inulin in urine and blood samples are measured by flurometer and GFR is calculated by the concentration of FITC-inulin in 24-hour-urine and the concentration of FITC-inulin in plasma. | University of Michigan - Ann Arbor | https://mmpc.org/shared/document.aspx?id=310&docType=Protocol | 1 | 2019 | Jeff Hodgin 2019.

UC Davis - Glucagon Resource Report Resource Website |
Peter Havel | 10.17504/protocols.io.63ihgke | Mouse Metabolic Phenotyping Centers | Glucagon is a 29 amino acid polypeptide processed from proglucagon in pancreatic alpha cells. In intestinal L-cells proglucagon is cleaved into glicentin, corresponding to proglucagon residues no 1-69. Glicentin can further be processed into oxyntomodulin, corresponding to proglucagon residues no 33-69. These peptides are released simultaneously upon stimulation. Moreover, a fragment of glucagon corresponding to its Cterminal part (residues no 19-29), also designated mini-glucagon, is reported to be present in the pancreas in low amounts compared to the total glucagon content. In general, glucagon has an effect opposite that of insulin, i.e. it raises blood glucose levels. It causes the liver to convert glycogen into glucose, which is then released into the blood stream. With longer stimulation, glucagon action in the liver results in a glucose-sparing activation of free fatty acid oxidation and production of ketones. During hypoglycaemia, glucagon secretion offers a protective feedback mechanism, defending the organism against damaging effects of glucose deficiency in the brain and nerves. | RRID:AB_2783839 | University of California, Davis | https://mmpc.org/shared/document.aspx?id=264&docType=Protocol | 2 | 2019 | Peter Havel 2019.
