Intestinal lipid absorption in the conscious mouse-lymph fistula (per animal)
This procedure enables the study of the intestinal digestion, absorption and lymphatic transport of dietary lipid in the conscious mouse. By infusing the lipid test meal intraduadenally at a constant rate, the lymphatic lipid output usually reaches a steady rate by the 3rd or 4th hour. Thus, lymphatic lipid output during the 5th or 6th hour represents the amount of lipid transported by the small intestine under steady-state conditions. At the end of the study, both luminal as well as mucosal radioactive lipids can be collected. Thus one can obtain a considerable amount of information regarding the digestion, uptake and mucosal esterification and the lymphatic transport of lipids.

Chronic high-fat 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.

Low levels of ALT are normally found in the blood. But when the liver is damaged or diseased, it releases ALT into the bloodstream, which makes ALT levels go up. Most increases in ALT levels are caused by liver damage. The ALT test is often done along with other tests that check for liver damage, including aspartate aminotransferase (AST), alkaline phosphatase, lactate dehydrogenase (LDH), and bilirubin. Both ALT and AST levels are reliable tests for liver damage.

Hyperinsulinemic-euglycemic clamp
A survival surgery with anesthesia is performed at 4~5 days prior to the clamp to establish a chronic indwelling catheter in the right jugular vein for intravenous infusion during the clamp. On the day of experiment, a mouse fasted for overnight (14-hr; 18:00-08:00) or 5 hrs (07:00-12:00) is placed in an over-sized restrainer (i.e., rat-sized) for the experiment to be conducted in fully conscious and minimally-stressed state. The tail is tape-tethered at one end to obtain blood samples from the tail vessel during the clamp. This procedure is applied for 2 hours before the clamp (basal period) for acclimatization in this partially-restrained state and recovery from the initial handling. Intravenous catheter is connected to a microdialysis infusion pump via a 3-way connector. During the basal period, D-[3-3H]glucose is infused at 0.05 ?Ci/min to assess basal glucose turnover. A blood sample (40 ?l) is collected at the end for the basal measurement of plasma glucose, insulin, and [3H]glucose concentrations. Following the basal period, a 2-hr hyperinsulinemic-euglycemic clamp begins with a primed (150 mU per kg body weight) and 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 (10 ?l) are collected at 10~20 min intervals for the immediate measurement of plasma glucose using glucose analyzer, and 20% dextrose is infused at variable rates to maintain basal glucose levels (~7 mM). Insulin-stimulated whole body glucose turnover rate is measured with a continuous infusion of [3H]glucose throughout the clamp (0.1 ?Ci/min). To estimate glucose uptake in individual organs, 2-[1-14C]deoxy-D-glucose (2-[14C]DG) is administered as a bolus (10 ?Ci) at 75 min after the start of clamp. Blood samples (20 ?l) are taken at 80, 85, 90, 100, 110, and 120 min of clamp for the measurement of plasma [3H]glucose, 3H2O, and 2-[14C]DG concentrations. Additional blood sample (20 ?l) is taken at 120 min to measure clamp plasma insulin levels. At the end of clamp, the mouse is anesthetized using sodium pentobarbital, and tissue samples (gastrocnemius and quadriceps from both hindlimbs, epididymal white adipose tissue, interscapular brown adipose tissue, liver, and heart) are taken for biochemical analyses. Serum and tissue samples may be transferred to the Analytical Core for analytical measurements (e.g., insulin, adipokines). The hyperinsulinemic-euglycemic clamp is a “gold-standard” method of measuring insulin sensitivity and generates the following metabolic data: - Insulin-stimulated whole body glucose turnover, glycolysis, and glycogen synthesis - Basal and insulin-stimulated rates of hepatic glucose production - Insulin-stimulated glucose uptake, glycogen synthesis, and glycolysis in individual organs Further details of the clamp experiment and calculation of clamp-derived parameters can be found in the following references: Diabetes 53:1060-1067 (2004), Stocker (ed.), Type 2 Diabetes, Methods in Molecular Biology, Vol. 560:221-238 (2009)

A survival surgery with anesthesia is performed at 4~5 days prior to the clamp to establish a chronic indwelling catheter in the right jugular vein for intravenous infusion during the clamp.

The tail is tape-tethered at one end to obtain blood samples from the tail vessel during the clamp. Intravenous catheter is connected to a microdialysis infusion pump, and a blood sample (20 ?l) is collected to measure basal glucose and insulin concentrations. A 2-hr hyperglycemic clamp begins with a variable infusion of 20% dextrose to raise and maintain plasma glucose concentration at ~300 mg/dl. Blood samples (20 ?l) are collected at 0, 10, 20, 30, 45, 60, 80, 100, and 120 min to measure plasma glucose and insulin concentrations using glucose analyzer and Luminex, respectively. At the end of clamp, the mouse may be anesthetized, and pancreas may be collected for islet isolation and histology/molecular analyses by the Analytical Core. The area-under-curve of plasma insulin levels indicates glucose-induced insulin secretion or in vivo pancreatic ?-cell function. In addition to insulin, c-peptide levels may be measured using additional blood samples for direct assessment of glucose-induced insulin secretion in mouse models potentially affected by altered hepatic insulin clearance.

Plasma [14C]palmitate concentrations are measured using liquid scintillation counter to assess systemic clearance of [14C]palmitate. Alternatively, [3-3H]glucose (20 uCi) is intraperitoneally administered as a bolus, and mice are euthanized after 1 hour for tissue collection. Biochemical assays are performed to measure [3-3H]glucose incorporation into [3H]-labeled triglyceride in individual organs.

Protein metabolism
Protein metabolism is assessed using the flooding-dose method previously described by Dr. Thomas C. Vary (Am. J. Physiol. 262:C445-452, 1992; Am. J. Physiol. 262:C1513-1519, 1992). The experiment begins with an intraperitoneal bolus injection of [3H]-L-phenylalanine (0.2 uCi/ml/umol, 30uCi/100 g/body weight; 1 ml/100 g/body weight) in conscious mice. After 15 min, mice are euthanized, and blood and tissue samples are rapidly taken for biochemical analyses. Blood samples are used to measure plasma phenylalanine and [3H]-L-phenylalanine concentrations. The phenylalanine levels are measured by HPLC analysis of supernatants from trichloroacetic acid extracts of plasma samples. The assumption in using this technique to estimate the rate of protein synthesis in vivo is that the tissue phenylalanine concentration is elevated to a high level thereby limiting any dilution effect of non-radioactive phenylalanine derived from proteolysis on the intracellular specific radioactivity. Under the condition of elevated plasma phenylalanine level (~1.2 mM), the specific radioactivity of the plasma phenylalanine is assumed to be equal to the specific radioactivity of the tRNA-bound phenylalanine.

Body composition (whole body)
Whole body composition of fat/lean/water mass is non-invasively measured in conscious mice using 1H-MRS developed by Echo Medical Systems (EchoMRI 3-in-1). This instrument has an important advantage over commonly used mouse densitometer (PIXImus), which applies dual energy x-ray technology for analysis of body composition in anesthetized mice. In contrast, 1H-MRS can be applied in studies requiring multiple measurement in individual mice, such as chronic changes in adiposity in response to a high-fat diet, without the risk of anesthesia-associated complications.

Energy balance – food intake, energy expenditure, physical activity
Metabolic cages (TSE Systems) are used to perform indirect calorimetry and simultaneously measure food/water intake, energy expenditure, and physical activity in conscious mice. The experiment non-invasively measures VO2 consumption and VCO2 production in individual mice using metabolic chambers and calculates the respiratory exchange ratio (RER) to reflect energy expenditure. RER values close to 1.0 reflects carbohydrate utilization, and RER values close to 0.7 reflects lipid utilization. The metabolic cages are also used for the quantitative measurement of horizontal and vertical movement (XYZ-axis) as an index of physical activity and food/water intake over a given period of time (typically 3 days). TSE metabolic cages provide natural food intake setting with cage-lid location of food, and mice tend to quickly acclimate to the TSE metabolic cages with natural cage setting during the 3-day measurements.

Chronic high-fat feeding
An experimental mouse model of obesity can be generated by feeding a high-fat diet (HFD) ad libitum for select duration. Quality control studies indicate that a short-term (3-4 weeks) of HFD feeding increases whole body fat mass by more than 2-fold and causes insulin resistance in male C57BL/6 mice. Most of the mice fed short-term HFD develop compensatory hyperinsulinemia but do not develop hyperglycemia. Chronic HFD feeding of longer term (2-6 months) further increases obesity and exacerbates insulin resistance in skeletal muscle, liver, adipose tissue, and heart. Most of the mice fed chronic HFD develop hyperglycemia, a hallmark of type 2 diabetes. The Metabolism Core works with the users in designing a study with appropriate feeding duration and selection of HFD with respect to percent and composition of fat in the diet.

STZ-induced type 1 diabetes model
An experimental mouse model of hyperglycemia and type 1 diabetes can be generated by intraperitoneal injection of streptozotocin (STZ; 50 mg/kg daily for 5 days), which selectively destroys the pancreatic beta-cells with rapid and irreversible necrosis. STZ-injected mice develop hypoinsulinemia within several days and thereby, hyperglycemia. Following STZ injection, blood glucose levels are monitored for the onset and maintenance of hyperglycemia. For selected mouse models, other STZ doses may be required to maintain chronic hyperglycemia. With onset of hyperglycemia and significant urinary loss of glucose, mice are closely monitored for proper hydration with adequate water supply and frequent change of cage bedding.

Acute lipid infusion
An experimental model of acute hyperlipidemia can be generated by an intravenous infusion of lipid emulsion at a rate of 2.5 ml/kg body weight/hour and heparin (6 U/hour). A 2-hour hyperinsulinemic-euglycemic clamp experiment may follow acute lipid infusion to measure insulin sensitivity in conscious mice exposed to acute hyperlipidemia. Quality control studies indicate that an acute lipid infusion for 5 hours increases serum fatty acids levels to 3~4 mM and causes insulin resistance in skeletal muscle. Lipid emulsion may be infused at different rates to raise serum fatty acids to different levels. This study allows users to investigate acute and direct effects of fatty acids without altering obesity or adipokines that may affect glucose metabolism.

Surgery – jugular vein cannulation
At 4-5 days prior to metabolic experiments requiring intravenous infusion, a survival surgery is performed to place an indwelling intravenous catheter in anesthetized mice. Experiments are performed 4-5 days after the surgery in order for the mice to fully recuperate from surgery/anesthesia stress, which is measured by a regain of body weight to pre-operative level. Mice are anesthetized with an intraperitoneal injection of ketamine (100 mg/kg body weight) and xylazine (10 mg/kg body weight). A transverse incision (~0.5 cm) is made over the trachea, and the right jugular vein is isolated. A silastic catheter (PE 10) is inserted into the vessel. The catheter is filled with a saline solution containing heparin (10 U/ml) and plugged. The catheter is then tunneled to the back of the neck, and placed under the back skin to prevent its accessibility from the mouse. A silk is tied to the catheter, and a small opening is made at the back of neck. This silk, which is partially exposed, is used on the day of metabolic experiment to expose and connect the catheter. The catheter requires no other care until the experiment day when it is flushed with a heparinised saline solution to reopen. This surgery requires ~15 minutes to complete. All surgical procedures are performed using standardized aseptic techniques, and all surgical tools are autoclaved following the surgery. In order to prevent hypothermia, a heating pad is used during the surgery, while a heating lamp and/or heating pad is used during the post-operative recovery period. After surgery, the mice are monitored closely in a post-operative cage with gauze bedding. Mice are monitored until they are awake and about which is usually within 1-2 hours. Mice are then housed in individual cages and monitored for post-operative recovery and weight gain on a daily basis for 48 hours for evidence of catheter infection.

Glucose
Plasma glucose concentrations are determined for a variety of metabolic experiments (e.g., hyperinsulinemic-euglycemic clamp, hyperglycemic clamp, GTT, ITT) performed by the Metabolism Core and for stand-alone measurements as a marker of perturbed glucose homeostasis in mice. Plasma glucose concentrations are measured by the glucose oxidase method using Analox GM7 Micro-stat Rapid Multi-assay Analyzer (Analox Instruments, Holliston, MA). This instrument requires 5 ul of plasma for rapid (~5 seconds) and accurate measure of glucose concentrations, which is important for select metabolic experiments such as hyperinsulinemic-euglycemic clamp and hyperglycemic clamp. Alternatively, blood glucose concentrations are measured using a glucometer for those metabolic experiments (e.g., GTT, ITT) that may be repeated in individual mouse.

Chronic intravenous infusion
Following jugular cannulation with cervical wire placement, mouse is single-housed in a round-bottom infusion chamber in a light, temperature and humidity-controlled environment, with ad libitum access to food and water. After a 2-day operative recovery period, continuous intravenous infusion of desired approved infusate is maintained for 24-96 hours using a high-precision syringe pump. Mouse body weight and chow intake are measured daily (recovery and infusion). Tail blood samples to measure glucose and plasma insulin are obtained daily during infusion. At infusion end, blood and tissue can be collected for histology or molecular studies.

Humanized Mouse (normoglycemic NSG mouse)
Normoglycemic NOD-scid IL2rgamma null (NSG) mouse transplanted with human islets. Although mouse models of diabetes have facilitated our understanding of human disease, there are notable differences in physiology particularly relating to islet composition and function between mice and humans. A “humanized mouse” is defined as an immunodeficient mouse engrafted with human primary haematopoietic cells and tissues to generate a functional human immune system. Information about the NSG mouse can be found in the following article: Friedline RH, et al. FASEB J. 2016;30:1328-1338.

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.
