Kristin Evans 10.17504/protocols.io.za3f2gn Mouse Metabolic Phenotyping Centers Summary: Vertical sleeve Gastrectomy (VSG) is a common surgical treatment of obesity, type-2 diabetes, and other comorbidities of obesity. The VSG mouse surgical model provides researchers with a mechanism to evaluate mechanistic studies to explore the methods by which VSG bariatric surgery produces beneficial effects on obesity. The surgical procedure is performed under sterile conditions in accordance with AAALAC standards. Surgical animals will be able to ship 2 weeks after the post-operative monitoring period is completed. Cohorts of Vertical Sleeve gastrectomy (VSG), a pair fed SHAM, and an ad lib SHAM will be provided with each cohort ordered.

Louise Lantier 10.17504/protocols.io.yzzfx76 Mouse Metabolic Phenotyping Centers The glucose tolerance test measures the clearance of an intraperitoneally injected glucose load from the body. It is used to detect disturbances in glucose metabolism that can be linked to diabetes or metabolic syndrome. Animals are fasted for 5 hours, fasted blood glucose levels are determined before a solution of glucose is administered by intra-peritoneal (IP) injection. Subsequently, the blood glucose level is measured at different time points during the following 90 minutes.

UC Davis - Comprehensive Laboratory Animal Monitoring System (CLAMS)
 
Resource Report
Resource Website
Peter Takeuchi, Trina Knotts 10.17504/protocols.io.yggfttw Mouse Metabolic Phenotyping Centers Energy expenditure is measured using an indirect respiration calorimetry system (CLAMS, Columbus Instruments, Columbus, OH). Air is drawn through calorimetry chambers and flow rate is controlled and measured with a mass flow controller. Oxygen consumption and carbon dioxide production are measured and used to calculate energy expenditure (or heat production, kilocalories (kcal)) and respiratory exchange ratio (RER: VCO2/VO2). The calorimetry chambers are also equipped with sensors, which allow the measurement of physical activity, food intake and water intake. All calorimetry chambers are housed within a temperature and light controlled incubator. The system contains 8 calorimetry chambers. 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). To investigate the influence of exercise on energy expenditure and substrate oxidation, the chambers can also be fitted with running wheels or the animals can be placed in separate chambers containing treadmills.

UC Davis - Urea Protocol
 
Resource Report
Resource Website
Peter Havel 10.17504/protocols.io.yw6fxhe Mouse Metabolic Phenotyping Centers Summary: The enzyme methodology employed in this reagent is based on the reaction first described by Talke and Schubert. To shorten and simplify the assay, the calculations are based on the discovery of Tiffany, et al. that urea concentration is proportional to absorbance change over a fixed time interval. The reaction is monitored by measuring the rate of decrease in absorbance at 340 nm as NADH is converted to NAD.

UC Davis - Creatinine Protocol
 
Resource Report
Resource Website
Peter Havel 10.17504/protocols.io.ygjftun Mouse Metabolic Phenotyping Centers The method employed here is based on an enzymatic colorimetric determination of creatinine which largely eliminates interferences known to the Jaffe method. In the final reaction sequence, the formation of the quinoneimine dye product results in an increase in absorbance at 550 nm (530-570 nm) which is directly proportional to the creatinine concentration in the sample. Potential interference from endogenous creatine and sarcosine are eliminated by the reaction of creatine amidinohydrolase, sarcosine oxidase and catalase before creatinine is determined. Ascorbate oxidase is included in the reagent to eliminate the influence of ascorbate in the sample.

UC Davis - Glutathione Peroxidase
 
Resource Report
Resource Website
Peter Havel 10.17504/protocols.io.ykdfus6 Mouse Metabolic Phenotyping Centers Summary: Glutathione peroxidase (GPx) catalyzes the reduction of hydroperoxides, including hydrogen peroxides, by reduced glutathione and functions to protect the cell from oxidative damage. With the exception of phospholipid-hydroperoxide GPx, a monomer, all of the GPx enzymes are tetramers of four identical subunits. Each subunit contains a selenocysteine in the active site which participates directly in the two-electron reduction of the peroxide substrate. The enzyme uses glutathione as the ultimate electron donor to regenerate the reduced form of the selenocysteine. The Cayman Chemical Glutathione Peroxidase Assay Kit measures GPx activity indirectly by a coupled reaction with glutathione reductase (GR). Oxidized glutathione (GSSG), produced upon reduction of an organic hydroperoxide by GPx, is recycled to its reduced state by GR and NADPH. The oxidation of NADPH to NADP+ is accompanied by a decrease in absorbance at 340 nm. The rate of decrease in the A340 is directly proportional to the GPx activity in the sample. The Cayman GPx Assay Kit can be used to measure all of the glutathione- dependent peroxidases in plasma, erythrocyte lysates, tissue homogenates, and cell lysates.
