Chronic high-fat/high sugar diet feeding
An experimental mouse model of obesity can be generated by feeding either a high fat diet (HFD) or very high fat diet (VHFD) for specified period of time; diet based on investigator preference for study needs. Differences in body weight can be seen as soon as 2 weeks after the initiation of feeding HFD. After 4 weeks on HFD, many mice begin exhibiting hyperglycemia with the full obese phenotype measureable after 16 weeks. Within 16-20 weeks mice may experience a 20-30% increase in body weight, adipocyte hyperplasia, fat deposition in the mesentery, increased fat mass, diabetes, and hypertension. The effect of the diet on obesity development is directly related to the fat content of the diet and the length of time the animal spends on the diet with variability in severity of metabolic changes observed between individual animals. The Animal Care Core works with the users in designing a study with appropriate feeding duration and selection of diet with respect to percent and composition of fat in the diet.

Animal Importation
In order to begin the process of importing animals, the Principal Investigator (PI) or designated laboratory staff member must submit a Shipping Form (Import) via the eResearch Animal Management (eRAM) system. On average, it takes approximately 2-3 weeks to complete a domestic shipment once the Shipping Form has been submitted in eRAM. This process takes longer for international shipments. For additional information, please visit Michigan's Animal Care and Use Program webite at http://animalcare.umich.edu/animal-use/transporting-animals Study teams who wish to have animals shipped to the University of Michigan from other institutions or non-commercial (approved) vendors should contact the ULAM Rodent Health Surveillance Team at ulam-rhst@umich.edu or (734) 936-1699 at least two weeks in advance of desired delivery date. All rodents shipped internationally to the U-M must have a negative test for Ectromelia virus, the causative agent of Mousepox. Please note that rodents who test positive for Ectromelia virus, or that have not been tested, will not be accepted under any circumstances.
Please Inquire
MI1092
Quarantine per diem
All rodents shipped to the U-M from non-approved vendors and/or other institutions must be quarantined for approximately three weeks to avoid the possible introduction of infectious agents to the University’s rodent colonies. Animals in quarantine are tested for viral, bacterial, and parasitic agents. If animals test positive for rodent viral, bacterial, or parasitic infections while in quarantine, they must be treated for the infection and, if appropriate, re-derived by embryo transfer via the Transgenic Animal Model Core or used in non-survival experiments. The same is true for rodents that are known to be positive at the time of shipment to U-M. Accordingly, ULAM Veterinary Staff strongly discourages investigators from acquiring research animals with known rodent viral, bacterial, or parasitic infections. Investigators are responsible for paying all quarantine-associated costs, including technician time, laboratory testing, and per-diems. Once the animals are released from quarantine, ULAM will transfer them to the appropriate animal housing room. Study teams who wish to have animals shipped to the University of Michigan from other institutions or non-commercial (approved) vendors should contact the ULAM Rodent Health Surveillance Team at ulam-rhst@umich.edu(link sends e-mail) or (734) 936-1699 at least two weeks in advance of desired delivery date.

ICV cannulation
Implantation of a cerebral ventricle cannula allows investigators to evaluate physiological responses following central administration of various compounds. Anesthetized mice are placed in a digital stereotaxic apparatus (0.001 mm accuracy, Cartesian Instruments) specifically designed for mice. The dorsal scalp will be shaved, wiped with a betadine solution, and then a small midline incision over the dorsal surface is made to allow access to the cranium. After the affixed centering scope is used to "zero" lambda and bregma landmarks, a single guide cannula (2.5 mm length, 26-gauge, Plastics One) is positioned 1.0 mm above the lateral ventricle (coordinates: 0.6 mm posterior to bregma, 1.5 mm lateral to midline, 1.4 mm below the surface of the skull) and fixed to the skull using two stainless steel screws and dental cement. The incision in the scalp is then closed with surgical thread. Animals are removed to a post-surgical warming bed, and then individually housed for several hours until fully awake. Animals will be allowed to recover from surgery for a minimum of 7 days prior to testing, during which time a 30-gauge dummy cannula is left inside the guide cannula to prevent blockage.

Jugular vein and carotid artery catheterization
Arterial catheterization allows investigators to sample arterial blood as required for adequate glucose clamping (Niswender et al. J. Biol. Chem, 1997, Halseth et al. Am. J. Physiol. 1999) or other infusion/sampling purposes (Rottman et al. Am. J. Physiol. 1999) Catheterization of the right jugular vein allows the infusion of hormones, substrates, and tracers into the systemic circulation. The jugular venous catheter can be used to sample venous blood in long-term experiments because the jugular vein catheter will work for almost a month.
Arterial catheters are made from polyethylene tubing (PE-10) that is connected to silicone tubing (0.3 mm I.D., and 0.64 mm O.D.), 25 mm long. Jugular vein catheters are made from silicone tubing (0.3 mm I.D., and 0.64 mm O.D.). These catheters are connected to stainless steel tubes (0.3 mm I.D., 0.41 mm O.D., 15 mm) bent into an L shape. On the free end of the L shaped stainless steel tube a 20 mm piece of micro-renathane tubing (0.36 mm I.D., and 0.84 mm O.D.) is attached. The L shaped stainless steel tubes, attached to an arterial and a jugular vein catheter, are bundled together with silicone tubing (0.76 mm I.D. and 1.65 mm O.D.) and anchored with silastic medical adhesive (Silicone Type A). The catheters and the micro-renathane-stainless steel tubing will be heat sterilized.
The mouse is anesthetized and its skin on the interscapula and ventral surface of the neck is depilated by plucking. The depilated area is sterilized with 10% povidone-iodine. A small longitudinal incision (about 5 mm) is made in the skin over where the anterior jugular, acromeodeltoid, and cephalic veins join together. The connective tissues surrounding this junction are carefully removed. Two thin threads of silk (6-0 Silk, Davis+Gech) are passed under the jugular vein below the level of the junction. They are separated by about 3 mm. The cephalic thread, placed just below the joint, is tied to prevent bleeding. A small incision is then made just below the ligature, and the catheter is pushed 13 mm into the lumen. The catheter is fixed with the second thread and the thread previously used to tie the jugular vein. The common carotid artery is separated from the vagus nerve and muscle, and then two thin threads of silk (6-0 Silk, Davis+Gech) are passed under the artery. The cephalic thread is tied to prevent bleeding and then the artery is clamped by small bulldog clamp. A small incision is made just below the ligature, and the catheter is inserted into the lumen. The clamp is taken off and the catheter is pushed in 10 mm. The catheter is fixed with a second thread and the thread previously used to prevent bleeding. A blunt needle (16 gauge) is carefully inserted through the incision on the interscapula and pushed subcutaneously until the end comes out through the incision in the neck. The catheters will be carefully seized and pulled slowly through the needle. The incisions in the skin are then sutured. The catheters are connected to the stainless steel tubes. The bent portion of the stainless steel tubing is implanted under the skin and the incision is sutured. The implanted catheter is flushed with saline containing 200 U heparin/ml and 1 mg ampicillin/ml. Then the micro-renathane tubing is closed with a stainless steel wire. The mouse is injected subcutaneously with 150 mg/kg ampicillin. The total duration of the operation is about 50 min. Animals are removed to a post-surgical warming bed, and monitored until fully awake. Postoperative body weight and food intake are measured daily.

Glucose Tolerance Test (Oral or i.p.)
Oral glucose tolerance tests are performed on conscious mice with catheters chronically implanted directly in the stomach and the carotid artery. Intravenous glucose tolerance tests are performed on conscious mice with catheters chronically implanted in the jugular vein and carotid artery. Glucose will be given at 1g/kg or 2g/kg. These doses lead to peak blood glucose levels of 250 mg/dl to 400 mg/dl in wild type C57/bl/6 mice.

Glucose turnover
A primed (2 µCi) continuous infusion of [3-3H]glucose (0.4 µCi/min) is used to assess the rates of glucose appearance (Ra) and disappearance (Rd). Tracer is infused to allow a steady state to be reached then blood samples are taken to assess arterial glucose specific activity. Ra will be estimated as the ratio of the rate of infusion of [3-3H]glucose and the steady state plasma [3H] glucose specific activity (dpm/mg). Under steady state conditions, the rate of glucose disappearance (Rd) equals the rate of glucose appearance. The rate of glucose clearance is calculated by dividing the Rd by the arterial glucose concentration. Application of this technique is described by Niswender et al. J. Biol. Chem. 1997, and She et al. Mol. Cell. Biol. 2000.

Hyperinsulinemic clamp
The hyperinsulinemic clamp is used to measure insulin action in vivo. Hyperinsulinemic clamps are performed on conscious mice with catheters chronically implanted in the jugular vein and carotid artery. A continuous infusion of insulin is given. Glucose levels are monitored in arterial samples every 5-10 min using an Accuchek glucose analyzer that allows the analysis of glucose with only 1 µl of blood. Glucose is infused in the jugular vein catheter at rates necessary to achieve the desired glucose level, based on feedback from arterial glucose measurements. These methods allow assessment of the responsiveness of the body to insulin. Blood from a donor animal is infused to maintain blood volume. By combining this technique with the tracer method one can also examine the impact of insulin on suppression of endogenous glucose production. (1, 2)

Hyperglycemic clamp
The responsiveness of the pancreas to glucose is assessed using the hyperglycemic clamp. Hyperglycemic clamps are performed on conscious mice with catheters chronically implanted in the jugular vein and carotid artery. Our clamps include 11 arterial insulin measurements and 3 arterial c-peptide measures.
A defined hyperglycemic stimulus is created using a primed variable glucose infusion to raise the glucose level to twice basal for 120 min. An established priming algorithm is used to elevate glucose quickly.
Mice with extra copies of the glucokinase gene locus were demonstrated to have a blunted insulin response to hyperglycemia using this technique (Niswender et al. J. Biol. Chem. 1997).

Amino acid kinetics
The turnover of phenyalanine (3H ring 2,3,4,5,6 phenylalanine) , glutamine (U-14C-glutamine) and leucine (1-14C-leucine) is assessed by a primed continuous infusion of their respective isotopes for 2 hours (0.2-0.4 µCi/min). Blood samples (20 µl) are taken after a steady state is reached to assess plasma amino acid specific activity. Blood samples are mixed with an equal volume of 6% sulfosalicylic acid. Incorporation of tracer in tissue protein is used to assess tissue specific protein synthesis.

Tissue specific glucose uptake
Tissue specific glucose uptake is assessed by measuring the tissue specific uptake of [2- 3H]-deoxyglucose([2-3H]DG). [2-3H]DG is infused (0.2 µCi/min) for 40 minutes or injected (12 µCi) . Arterial plasma samples are taken to determine the time course of [2-3H]DG during the 40 min period. [2-3H]DG is transported into cells and phosphorylated to yield [2-3H]DG-6-phosphate which is trapped in muscle. After 40 min mice are anesthetized with an intravenous infusion of pentobarbital and tissues of interest are rapidly removed and frozen in liquid nitrogen. This method has been applied during insulin- and exercise-stimulated conditions (Halseth et al. Am. J. Physiol. 1999).

Indirect calorimetry / energy expenditure in the Promethion
Whole body VO2 and VCO2 is measured continuously in conscious mice using a Promethion system (Sable Systems Int). The system is sensitive enough to measure small changes in VO2, VCO2 and RQ. They can be used to measure resting or exercising (running wheels or treadmill) gas exchange and energy expenditure. The Promethion is very advanced, allowing for measurement and control of food or water intake. In the Promethion the animals are housed in regular home cages with normal bedding. Activity is measured using beam breaks and converted to pedestrian locomotion. Food and water intake are very accurately quantified. The system integrates all of these data to monitor behaviors and patterns. Body weight and composition is included and measured before and after the metabolic cages.
All mice remain in the Promethion cages for 5 days with continuous data collection, allowing for acclimation while also providing extensive data. Full data is reported to the investigator in excel format.

Food Consumption
Food consumption is assessed using an automated feeding apparatus that continually measure feeding behavior in an unobtrusive manner by allowing animals free access to food cups that are mounted on balances. The apparatus currently is capable of measuring and time-stamping individual weights from 16 balances simultaneously every 30 seconds and downloading the data directly to a computer for subsequent analysis. Therefore, cumulative food consumed and the time at which feeding bouts occur are continuously monitored. All feeding studies are done after the animal has acclimatized to the facility for at least 24 hours.

Acute arterial blood pressure (via arterial catheter)
Blood pressure (BP) represents an integrated measure of overall cardiovascular function, and is affected by stroke volume, heart rate, inotropic state, and vascular tone. Abnormalities of BP regulation (primarily hypertension, but also hypotension) are associated with major cardiovascular morbidity and mortality, and are epidemiologically associated with diabetes and obesity.
Three complementary technologies are available for the measurement of BP: 1) non-invasive tail-cuff plethysmography, 2) direct arterial measurement by intracarotid catheterization, and 3) telemetry via implanted catheter.
(1) Tail-cuff Plethysmography. Plethysmography (tail-cuff) is performed using a tail-cuff BP apparatus (BP-2000, Visitech Systems, Inc.). This technology is non-invasive and there is good concordance with the direct BP measurements described below.
(2) Carotid Catheterization. Direct arterial measurements are obtained via a chronically placed catheter in the carotid artery. The catheter is connected to a TXD-310 transducer and BP measured using a Digi-Med BPA 400 (Micromed). Experiments using this approach are typically coordinated with metabolic measurements.
A dual catheter approach (arterial and venous) allows for BP measurements in response to specific pharmacological infusions in the awake or anesthetized state; and enables evaluation of both peripheral and central mechanisms of BP regulation.
(3) Telemetry. Telemetered direct BP measurement is performed using an implanted micro-miniature device (PA-C10, DSI) implanted subcutaneously with the catheter typically placed in the right carotid artery. The mouse is housed individually in a cage placed over the receiver platform and BP data digitally recorded via the DATAquest A.R.T. system (DSI). Advantages of this approach include the ability to continuously record BP over a period of weeks, to assess the diurnal range in BP, and stress artifact induced by animal handling is avoided.

The biliopancreatic diversion procedure in the mouse: This procedure is historically thought to be a malabsorptive procedure and has several variations in the human. In brief, the biliary and pancreatic secretions are physically separated from gastrointestinal chyme flow until a point near the terminal small bowel. In theory this leads to significant malabsorption, though when this procedure is done clinically many times a gastric restriction component is also added.

Hyperinsulinemic-euglycemic clamp experiments
The surgery is performed at 4-5 days prior to the hyperinsulinemic-euglycemic clamp to establish a chronic catheter for intravenous infusion of substances (e.g., glucose, insulin) during the clamp. For this, a mouse is anesthetized with an intraperitoneal injection of ketamine and xylazine, and a catheter is inserted in the right jugular vein. On the day of clamp experiment, an overnight-fasted mouse is placed in an over-sized restrainer (i.e., rat-sized) for the experiment to be conducted in awake and minimally-stressed state. The tail is tethered using a tape for 2 hours prior to the start of experiment for acclimatization. A 3-way connector is attached to the jugular vein catheter for intravenous infusion, and the blood samples are obtained from the tail vessels requiring a small tail cut. A 2-hour hyperinsulinemic-euglycemic clamp is conducted with a primed-continuous infusion of human insulin at a rate of 15 pmol/kg/min to raise plasma insulin within a physiological range (~300 pM). Blood samples (20 ml) are collected at 10-20 min intervals for the immediate measurement of plasma glucose concentration, and 20% glucose is infused at variable rates to maintain glucose at basal concentrations (~6 mM). Insulin-stimulated whole body glucose metabolism is assessed with a continuous infusion of [3-3H]glucose (0.1 mCi/min) throughout the clamps. Basal rates of whole body glucose turnover are assessed using a primed-continuous infusion of [3-3H]glucose for 2 hours prior to the start of clamp. All infusions are performed using the microdialysis pumps, and all procedures are approved by Yale University Animal Care and Use Committee. To estimate insulin-stimulated glucose uptake in individual tissues, 2-deoxy-D-[1-14C]glucose (2-[14C]DG) is administered as a bolus (10 mCi) at 75 min after the start of clamp. Blood samples (20 ml) are taken at -5, 80, 85, 90, 100, 110, and 120 min of clamp for the measurement of plasma [3H]glucose, 3H2O, and/or 2-[14C]DG concentrations. Additional blood samples (20 ml) are collected before and at the end of clamp for the measurement of plasma insulin concentrations. At the end of clamp, mouse is anesthetized with sodium pentobarbital injection, and tissues are taken and stored for biochemical/molecular analysis. The clamp experiment measures tissue-specific insulin action and glucose metabolism and includes the following measurements: 1) basal and insulin-stimulated hepatic glucose production, 2) insulin-stimulated whole body glucose uptake, glycolysis, and glycogen plus lipid synthesis, and 3)insulin-stimulated glucose uptake, glycolysis, and glycogen synthesis in individual tissues (e.g., skeletal muscle, adipose tissue, heart). Additionally, biochemical/molecular assays may be performed to assess tissue-specific insulin signaling activities (e.g., insulin-stimulated tyrosine phosphorylation of IRS, PI 3-kinase activity) and tissue-specific triglyceride contents. Further details of the clamp experiment can be found in the following references: Diabetes 53:1060 (2004), J. Clin. Invest. 114:823 (2004).
