Stable Isotopes in Metabolomics and Metabolism

Researcher
Perspective

Gary J. Patti
Department of Chemistry and Department of Medicine
Washington University, St. Louis, MO 63130 USA

Recent advances in mass spectrometry (MS) and nuclear magnetic
resonance (NMR) technologies have greatly enhanced metabolite
analysis. Hundreds to thousands of metabolites can now bemeasured simultaneously with unprecedented accuracy fromexceedingly small amounts of biological material. These technicaldevelopments have given rise to the field of metabolomics, which
generally aims to assess metabolic regulation as a function ofhealth and disease. During the last decade, it has become relatively
routine to perform metabolomics analysis on most biologicalsamples. Interpretation of the acquired data, however, remains aconsiderable challenge. Stable isotopes are providing experimental
strategies that overcome some of these barriers. One obstacle inperforming metabolomics is that many of the signals or peaks
detected by MS do not correspond to unique metabolites of
biological relevance. Rather, it has been demonstrated that
hundreds to thousands of MS peaks arise from contaminants andartifacts. Given that many endogenous metabolites are derived
from a nutrient precursor, isotopic labeling is being used to
distinguish biologically derived metabolites from experimental
noise. Additionally, because the incorporation of stable isotopes
generally does not affect the retention time or ionization efficiencyof metabolites, isotopically labeled compounds are the gold
standard for quantifying the concentration of endogenous
metabolites within a complex biological matrix.
Beyond their role in improving the analytical accuracy ofmetabolomics, isotopes can also be used as tracers in metabolic
analyses. When metabolomics is performed without stable isotopic
tracers, only metabolite concentrations can be determined.
When metabolomics is performed with stable isotopic tracers,in contrast, both metabolite concentrations and pathway
activities (i.e., metabolic fluxes) can be assessed. The latterprovides a much richer understanding of metabolism.
While measuring metabolite concentrations without isotopes cancertainly be insightful, such measurements reveal only part of thestory. They provide a mere snapshot of metabolism that cannot betranslated into a dynamic map of metabolite traffic on biochemical

6routes. When comparing two sample groups, an elevatedmetabolite level may indicate increased or decreased
pathway flux. This is because metabolites can accumulate
not only due to increased production, but also due todecreased consumption. Yet, the difference between increased
production and decreased consumption may yield entirely different
experimental interpretations. In a biomedical context, for example,
increased production of a metabolite may suggest pharmacologicalinhibition of the pathway as a therapeutic strategy. Thus, tounderstand pathway regulation and metabolic mechanismsof disease, the application of isotopic tracers is required.
In addition to enabling assessment of metabolic fluxes, isotopic
tracers also add biochemical resolution to metabolomics analyses.
Most metabolites lie at the intersection of multiple metabolic
pathways. Without isotopic labeling, only a single metabolite
pool is measured. It is not possible to distinguish the amountof this pool that is associated with one metabolic pathway
relative to another. By using isotopic tracers, on the other
hand, the fraction of the metabolic pool associated witha specific pathway can be delineated with labeling. As an
example, palmitate can be synthesized from numerous
metabolic substrates such as glucose, glutamine, acetate,etc. Stable isotopic tracers enable the fraction of palmitate
produced from each precursor to be quantified.
Importantly, most modern MS and NMR instrumentation is well
suited for the analysis of stable isotopes. Although processingof the data can be complicated, there are an increasing numberof user-friendly software platforms (some commercial and somefreely available). Moreover, when the appropriate isotopic tracer isselected, simple qualitative analyses of the data is often sufficientto yield important insight into metabolic pathway activities. Finally,
it is worth noting that isotopic tracing experiments are not limited
to micro-organisms that can be grown in defined media. To thecontrary, some of the most widely used applications of isotope
labeling have been in mammalian cell culture, plant and animalmodels, and in human patients.

Products
Amino Acids and Their Derivatives
Amino acids play critical roles in biological functions as building blocks of peptides and proteins, as well as intermediates of various
metabolic pathways (e.g., citric acid cycle, urea cycle). These compounds are also reported to influence the pathogenesis and propagationof metabolic disorders /disease, with clinically designed biomarker research aimed to detect disease at the earliest stage.
To aid qualitative and quantitative metabolic research, CIL offers an array of unlabeled and stable isotope-labeled free amino acids. Thesecan be used as internal standards or NMR probes in MS- and NMR-based research studies. The amino acids are canonical (e.g., arginine,lysine, phenylalanine) and noncanonical (e.g., beta-alanine, citrulline, ornithine). These are available in their uniform or specifically labeled(with 13C, 15N, D, and /or 18O) forms, in research or MPT grade.

Bile Acids
The analysis of bile acids (BAs) in biofluids is a developing and growing MS ‘omics field. These steroid-like compounds act as detergent
that assist in the breakdown of fats. The primary BAs are synthesized from cholesterol in the liver, while secondary BAs are converted fromprimary BAs in the colon. The bile acids can also be conjugated with glycine or taurine in the liver, which increase their solubility in water.
Bile acids have gained clinical attention by their linkage to colon cancer, liver disease, chronic diarrhea, cholestasis, hyperlipidemia, andgallstones. CIL is pleased to offer an extensive panel of primary and secondary BAs, in their free acid and conjugated salt forms. These
research-grade products are available as isotopically labeled and/or unlabeled standards in solution (at 100 µg /mL in methanol)
and/or neat form.

Caffeine and Its Metabolites
Caffeine is a psychoactive stimulant of the central nervous system that is extensively consumed worldwide. MS-based research into thekinetics/metabolism of this compound and its metabolites (e.g., paraxanthine, theobromine, theophylline) has revealed insight into
its health impact and abuse in humans. Studies further suggest an influence on pharmacological activity and neurodegeneration(e.g., Parkinson’s disease); thus, strengthening a need for its robust clinical analyses.
CIL offers stable isotope-labeled caffeine and a collection of isotopically labeled metabolites for basic and translational quantitative research.
These standards are available in various labeling patterns, with alternate compounds or labels evaluated upon request.

Carbohydrates
Carbohydrates are integral biomolecules to the function and process of living systems (e.g., in cell-to-cell signaling, immune responses,
protein folding). Although this family of compounds is structurally diverse and complex, analysis by LC- and GC-MS techniques has been
well adopted in the metabolomics field. Clinically, the quantitative analysis of sugars in human biosamples is of increasing importance forsuch disease screenings as cardiovascular and nonalcoholic fatty liver disease (NAFLD).
In addition to the classic monosaccharides (e.g., glucose, fructose, ribose) and sugar alcohols (e.g., erythritol, sorbitol, xylitol), CIL offers
a number of other stable isotope-labeled carbohydrates. The list includes monosaccharides, under the pentose (e.g., arabinose, erythrose)and hexose (e.g., galactose, mannose) classes, disaccharides (e.g., lactose, maltose, sucrose), and polysaccharides (e.g., starch). These
compounds are supplied with various labeling patterns as neat standards, in research or MPT grade.

Carnitine and Acylcarnitines
Carnitine and acylcarnitines play an essential role in fatty acid metabolism. Metabolism disorders of fatty acid oxidation and several organic
acidurias impose major clinical manifestations (e.g., hypoketotic hypoglycemia, skeletal myopathy, liver disease, and /or failure). These arelargely attributed to enzymatic deficiencies and can be monitored through carnitine/acylcarnitine measurement.
To help facilitate metabolic screening exercises, CIL is pleased to offer a variety of stable isotope-labeled and unlabeled carnitine/acylcarnitine
standards. Please refer to page 52 for a list of mix offerings; individual standards are noted below.

Drugs and Their Metabolites
The field and scope of drug screening/analysis continues to expand worldwide. Example areas of focus include therapeutic drug monitoring,drugs of abuse, prescription monitoring, and clinical toxicology. The nature of those monitored or identified in the MS-based analysis include
psychoactive drugs (e.g., benzodiazepines, cannabinoids, hallucinogens), pain-management drugs (e.g., analgesics, opiates, skeletal muscle
relaxants), disorder-related treatment drugs (e.g., anticonvulsants /antiepileptics, antipsychotics, erectile dysfunction), and infectious diseaseor disease-related treatment drugs (e.g., antibiotics, antiarrhythmics).
CIL is pleased to offer a broad collection of unlabeled and stable isotope-labeled standards to aid the qualitative/quantitative analysis ofdrugs and their metabolites. These encompass a multitude of classes (e.g., analgesics, benzodiazepines, cannabinoids and its agonists,
opiate and opioid analgesics, stimulants). The offerings are individual standards and /or class-specific mixtures in predominantly theirconcentrated solution form.
Available from CIL for customers in the US, Australia, Canada, and Switzerland. Contact us for sourcing details for other destinations. Products listed with anasterisk are available globally.

Fatty Acids and Lipids
Fatty acids and lipids are important biological compounds that are essential to the regulation and control of cellular functions andmetabolic pathways. These biomolecules are also tied to the energetic balance of an organism. Their qualitative /quantitative analysis
has emerged to better understand the underlying pathophysiology, as well as to identify new biomarkers or diagnose existing ones.
To aid such research initiatives, CIL is pleased to offer a multitude of stable isotope-labeled and unlabeled fatty acids and lipids.
The fatty acids cover saturated and unsaturated classes, while the lipids include ceramides (e.g., N-palmitoyl-D-sphingosine,N-oleoyl-D-sphingosine), and phospholipids (e.g., dodecylphosphocholine, dipalmitoyl phosphatidylcholine), as well as triacylglycerides(e.g., tripalmitin, tristearin, triolein). These are available in various labeling patterns (i.e., uniform, partial), forms (i.e., free acid, salt,
ester), and material grades (i.e., research, MPT).

Metabolomics Mixtures and Kits
Metabolomics is an increasingly important and growing area of research. The use of stable isotopes (as internal standards), in combination
with analytical techniques such as mass spectrometry, allow researchers to identify and quantify metabolites in a given biological sample.
This information can be used to better understand disease mechanisms, evaluate drug responses, and assess putative biomarkers,
amongst other targeted applications. To help facilitate such initiatives, CIL is pleased to offer a variety of mixes and kits. These aredesigned to aid ease of use in untargeted and targeted metabolomics exercises (e.g., in quantification, qualification, quality control,
system suitability). The mixtures are offered neat or as solutions, while the kits are additionally supplied with a user manual. The manuals
outline general procedures and processing tables (i.e., platform parameters and conditions), as well as alternate method suggestions anddata analysis guides for user reference. Supplemental figures and references in the user manuals provide additional user support.

MRS/MRI Tracers
Using stable isotopes in magnetic resonance spectroscopy (MRS) and magnetic resonance imaging (MRI) research takes advantage of thechanges in chemical shifts to measure rates of conversion between different molecules. Normally in these types of studies, stable isotope
compounds will contain D, 13C, 15N, and /or 17O as tracers. The ability to easily differentiate isotopomers is a huge advantage to using MRS/MRI as opposed to mass spectrometry in this work. There are different techniques that use MRS/MRI in tracer research, including:•	Hyperpolarization – allows for sensitivity increases of up to 100,000 times for short periods of time to image metabolite conversion.
•	Deuterium imaging – takes advantage of the very low deuterium background and chemical shifts differences to determine the rates.
•	Metabolomics/Metabolism – determines the fates of compounds or the number of turns of specific cycles.
CIL is pleased to offer a vast array of stable isotope-labeled compounds for use as tracers in MRS/MRI research. These materials are available
in their neat and/or solution form.

MS/MS Screening Mixtures and Standards
The utility of stable isotope-labeled standards for MS/MS screening is gaining traction worldwide. To support such research endeavors
and enhance method adoption, CIL is pleased to offer a breadth of high-quality, stable isotope-labeled mixtures. These mixes containa collection of stable isotope-labeled standards (e.g., 12 amino acids in NSK-A) and are class-specific (e.g., amino acids, carnitine/
acylcarnitines, steroids). These are available in 10-vial sets or single vials and are suitable for metabolite quantification in isotope
dilution MS (IDMS) experiments. Also listed here are example individual standards used in MS/MS screening research.

Neurotransmitters and Their Metabolites
Neurotransmitters are small chemicals in the central nervous system that modulate and regulate brain function. Signals are relayed fromneuron to neuron by release, upon stimulation, from a synaptic vesicle into a space where it can bind to a receptor. These molecules
can be grouped into several classes, such as catecholamines (e.g., dopamine, epinephrine) and indolamines (e.g., melatonin, serotonin).
MS analysis of neurotransmitters in human biosamples, such as urine, is a clinically relevant area as they mediate homeostatic function,
modulate neural activity, and have been correlated to the pathogenesis of neurodegenerative diseases (e.g., Alzheimer’s).
CIL offers an array of stable isotope-labeled neurotransmitters. These research-grade materials are available in their solution and/or neatform.

Nucleic Acids
Nucleic acids are necessary biomolecules of living systems, being fundamentally important to a multitude of cellular processes. Its basic
building blocks are nucleobases (e.g., adenine, cytosine, xanthine), nucleosides (e.g., adenosine, guanosine, inosine), and nucleotides(e.g., ATP, CMP, dGTP). The qualification /quantification of these compounds, and their synthetic analogues (e.g., allantoin, 5-fluorouracil,
pseudouridine), in biosamples is performed preclinically and clinically to address a number of purposes. This includes the screening of
metabolic errors and the efficacy evaluation of drug treatments (be it anticancer, antiviral, or immunosuppressive), among other target
areas.
CIL offers an array of stable isotope-labeled nucleic acid building blocks for MS- or NMR-based research. These standards are available
in a variety of labeling patterns and quantities.

Organic Acids and Their Conjugate Salts
Organic acids (OAs) play essential roles in energy metabolism pathways (e.g., glycolysis, tricarboxylic acid cycle), with the short-chained
OAs emerging as important regulators of host immune response and transcriptional regulation.
To aid quantitative research in preclinical and clinical studies, CIL is pleased to offer a collection of stable isotope-labeled and unlabeled
OAs and their conjugate salts. These encompass monocarboxylic (e.g., acetic, lactic), dicarboxylic (e.g., malic, succinic), and tricarboxylic(e.g., cis-aconitic, citric) acids.

Steroids and Hormones
Steroids and hormones play vital roles in the regulation of a diverse array of cellular functions and physiological processes. These pertain
to development, reproduction, homeostasis, and metabolism, among others. Accurate quantification of this compound class is essential
for basic and clinical translation research. This can be achieved by spiking an isotopically labeled steroid standard(s) into a sample ofinterest, such as plasma or urine, with measurement performed by an MS- or NMR-based approach.
CIL offers a variety of stable isotope-labeled and unlabeled steroids and hormones. These are available in different labeling patterns
in their neat and/or solution forms.

Vitamins and Their Metabolites
Vitamins are organic compounds that directly or indirectly participate in organisms’ biochemical reactions. These are divided into twoclasses, based on their solubility in fat (includes A, D, E, and K) and water (includes B and C).
CIL offers unlabeled and stable isotope-labeled vitamins as neat compounds and/or in solution at specified concentrations. These canbe used in a wide range of applications, such as metabolism and pathophysiology explorations, as well as disease biomarker evaluationin preclinical and clinical MS studies (e.g., vitamin D deficiency). These standards help facilitate accurate and precise quantificationof endogenous metabolites in biological matrices.

processing techniques (i.e., dialyzed, heat-inactivated, unprocessed),
may result in inconsistent cell culture phenotypes and growth rates.
Incorporating reliable QCs in the evaluation of FBS, when applied inmetabolomics to spent and control media, can help increase theoverall confidence of interpretations when this supplemental
material possesses variation.

Highlights• FBS is a common supplemental growth medium in cell
culture applications.
• QCs are imperative to maximizing the quality of metabolite
profiling and quantification data.
• QReSS metabolite mix is useful in assessing performanceefficiencies as well as in obtaining qualitative/quantitative
information on FBS compounds.
• Exceptional stability observed in the HILIC-MS analysis,
which supported the data extracted from the targeted anduntargeted MS analysis.

Here, the QReSS™ standard mixes (CIL cat no. MSK-QReSS1 andMSK-QReSS2) were used in the QC of metabolites from variably
sourced FBS samples. The QReSS standards are beneficial for QC
assessments because they comprise a chemically diverse set of 18
stable isotope-labeled metabolites that span a broad molecularweight range, possess varied ionization propensities, and cover a
distribution in class and retention time. Highlighted in addition to
the QC results is the absolute quantitation of known compounds
from targeted MS experiments and novel findings from anuntargeted workflow.

Introduction
Metabolomics is a rapidly growing field of research that has uniqueand proven advantages in systems biology and biomarker discovery.
Great advances have been made over the past decade on thefeasibility of mass spectrometry (MS)-based metabolomics. Despite
the advancements, there remains a pervasive need for quality
control (QC) as metabolomic experiments can experience unwanted
variations that threaten the quality of the acquired data.1,2 The useof reliable QC measures is therefore critical to assess and prevent
unwanted preanalytical and instrumental variation.3 Any systemerrors or outliers identified through QC testing must therefore becorrected to ensure consistent and meaningful metabolomics data.

Experimental
Materials
All reagents were of the highest available grade and solvents were
LC-MS grade. Manufacture recommendations were adhered to in
the storage of these chemicals and reagents. QCs and calibrants
were constructed with the QReSS kit mixes (stable isotope-labeled
and /or unlabeled; CIL cat no. MSK-QReSS-KIT and MSK-QReSSUS-KIT, respectively). The composition details of the labeled QReSS
standard mixes are outlined in Table 1. All QReSS mixes werestored at ambient temperature (protected from light and moisture)in their neat form and at 4°C upon solubilization. FBS samples (n =20) were obtained from four commercial vendors supplied acrossfive countries (i.e., USA, Canada, Mexico, Panama, and Australia).
These were treated by the vendor under different conditions (i.e.,
dialyzed, heat-inactivated, and unprocessed) and were storedaccording to supplier recommendations.

An area of metabolomics garnering great interest, particularly indiscovery efforts, is the profiling and quantitation of cell cultures.
In this in vitro application, fetal bovine serum (FBS) is commonlyused as a supplemental growth medium. FBS contains several
nutritional and macromolecular components, including a varietyof small molecules (e.g., amino acids, carbohydrates, lipids,
hormones) that are essential for cell growth and proliferation.

Introduction
One of the incessant challenges in mass spectrometry (MS)-based“omics” is the qualification of methods and instrument platforms.
Required are materials that can be used to routinely test platform
performance over time and to test assay effectiveness throughout
all phases of a work list.1,2 Such evaluations are necessary as itprovides an indicator to the effectiveness of an analytical method
and platform. Errors or deficiencies observed in the performance
would then cue corrective action. This could help save precious
samples and experimental resources, while also extend column
lifetimes.
In metabolomics, the test materials would be metabolites, withthe end product being a mixture that can be readily (and routinely)
applied for quality control (QC) and system suitability testing (SST).
The metabolites should be carefully selected and the mix wellcharacterized to enable reliable and continuous application. Ideally,
the metabolites should be diverse and embody broad coverage,
while not being overly complex in number as that could complicate
the multiplexed analysis of experimental samples. A commerciallyavailable kit that embodies these requisites, while additionallyoffering the benefit of identification and quantification in MS/MS
applications, is QReSS™ (Quantification, Retention, and System
Suitability).
The QReSS kit (CIL catalog no. MSK-QReSS-KIT) comprises twodried-down mixtures of stable isotope-labeled metabolites and adocument package. Included with the package is a user manual,
which outlines example procedures and illustrates sample results
for user reference. These mixes are well suited for qualification
applications due to the carefully selected compounds, theirinherent characteristics (e.g., molecular weight), and theirexperimental tendencies (e.g., broad elution behavior, absent
from solubility issues or stability concerns). Discussed here is thedevelopment of the QReSS mixes, experimental methods, andexample reversed phase (RP) LC-MS/MS results to illustrate theproducts utility in untargeted/targeted MS metabolomics.

Key Features/Benefits of QReSS Kits
• stable and reproducibly prepared mixes• predominantly 13C and/or 15N metabolites• concentration-balanced metabolites• user manual supplied for method guidance• broad coverage in metabolic compound class, molecularweight, and retention times• enables reliable performance tracking• allows qualification and quantification

Experimental
Materials
All chemicals were of the highest reagent grade available andwere stored in accordance to the suppliers’ recommendations.
The solvents used in the sample/eluent preparations were LC-MS
grade. Isotope-labeled QReSS mixes (see vial snapshots below
and Table 1 for composition details) were used as the metabolite
standards in the MS analyses. These were stored at ambient
temperature (protected from light and moisture) until use.
Human plasma (NIST SRM 1950) and human urine (BioIVT)
served as the test matrices.

Analysis of Whole-Body Branched-Chain
Amino Acid Metabolism in Mice Utilizing
20% Leucine 13C6 and 20% Valine
13
C5 Mouse Feed
Jared R. Mayers, Margaret E. Torrence, Brian P. Fiske, Shawn M. Davidson,
and Matthew G. Vander Heiden
Koch Institute for Integrative Cancer Research and Department of Biology, Massachusetts Institute of Technology, Cambridge, MA USA
Cancer cells have altered metabolism relative to normal cells.
To date, most cancer metabolism research has focused onunderstanding the mechanisms of cell autonomous metabolic
alterations such as the influence of different oncogenic signals
on nutrient utilization and the effects of altered regulation of
specific enzymes on metabolic fluxes through different pathways(Cairns RA et al. 2011). While these studies have provided insight
into metabolic needs of proliferating cancer cells (Vander Heiden
MG et al. 2009), they do not address potential interactions
between tumor and normal tissues.

In this note, we describe the experimental approaches weused to define the contribution of each of these pools to plasma
BCAA levels. A critical tool for these experiments was the customdesigned 20% leucine 13C6 and 20% valine 13C5 mouse feed dietdeveloped in collaboration with Cambridge Isotope Laboratories,
Inc. (CIL) and Harlan Laboratories, Inc.*

Research on whole-body metabolic alterations associated with
type 2 diabetes (T2DM) provides insight into how altered metabolite
sensing can affect the metabolism of specific tissues. Intriguingly,
there are clear epidemiological connections between diabetes andseveral types of cancer, especially pancreatic adenocarcinoma(PDAC) (Everhart J et al. 1995; Wang F et al. 2003). Indeed,epidemiologic evidence indicates that pancreatic cancer can beboth a consequence of longstanding diabetes (Ben Q et al. 2011)
and cause of new-onset cases (Huxley R et al. 2005). Methods tostudy metabolism across tissues are needed to understand howwhole-body metabolic alterations influence tumor metabolism,
and to understand the systemic changes associated withmetabolic disease.

13
C-BCAA amino acid-defined diet. The isotope-enriched diet,where 20% of the leucine and 20% of the valine were replaced bytheir stable isotope labeled forms, used recipe TD.130306. This was
based off of a modification of the control diet TD.110839.

In a recent study, we found that elevated branched-chain aminoacids (BCAAs – leucine, isoleucine and valine) are found in theserum of patients with early pancreatic cancers (Mayers JR et al.
2014). Using a genetically engineered mouse model of PDAC
(Bardeesy N et al. 2006) we used isotope-labeled diets to assess thesources of these plasma BCAA elevations and distinguish between
short-term pools defined by acute dietary uptake and disposal, andlong-term pools defined by turnover of whole-body protein stores.

Experimental Design
Experimental mice. Four-week-old male mice on a mixed
background were used in the studies described in this note.

Acute uptake and disposal. Following a 16-hour overnight fast,mice were fed the 13C-BCAA diet for two hours before removal offood. Food consumption during this period was measured. At thetime points indicated by the orange bars in Figure 1a, approximately
20 µL of plasma was harvested from the tail vein of conscious
mice in a heparinized tube and centrifuged to separate plasma.
Plasma was subsequently analyzed via gas chromatography/mass
spectrometry (GC-MS) to determine the number of ion countsof 13C-labeled species. This number was normalized to food intake
over the two-hour feeding window for each animal.
Long-term contributions to BCAA plasma pools. Mice were fed
13
C-BCAA diets from seven days of age to 24 days of age followedby three days of unlabeled diet per the experimental outline in
Figure 2a. Two cohorts of mice were used in this experiment. One
cohort of mice was sacrificed on day 27 (fed state) and a second

Lipids are ubiquitous molecules which serve a variety of importantbiological functions, including energy storage (triglycerides),modulation of cellular membrane structure and function(phospholipids and cholesterol), intracellular signaling, andhormonal regulation. Dysfunctions of lipid metabolism contributeto a variety of diseases including, among others, atherosclerosis,
hypertriglyceridemia, and type 2 diabetes. As such, understanding
the synthesis, regulation, and transport of lipids in the body isimportant to developing new and improved therapies for these
diseases. Stable isotopes have been used to study several aspectsof lipid metabolism including the synthesis and disposition ofcholesterol,1,2 phospholipids,3 and VLDL triglycerides.4 In thisapplication note, we highlight some of the advantages andexperimental considerations for using stable isotope-labeled
fatty acids as substrates to study lipid metabolism in vivo in mice.

Experimental Design
For experiments on lipid synthesis, C57BL6 mice were treatedwith a vehicle control or a systemic, small-molecule inhibitor of
microsomal triglyceride transfer protein (MTP).5 One hour later,
the mice were administered 150 mg/kg of oleic acid, potassium salt
(13C18, 98%) CP 95% (CLM-8856) mixed with corn oil (Figure 2)
or 20% TPGS (Figure 3). Blood samples were withdrawn at serial
timepoints following tracer administration and processed to plasma.
10 µL of plasma were mixed with 90 µL of methanol containing
heavy internal standards and further diluted with 300 µL of
pentanol. The samples were centrifuged briefly to pellet insoluble
proteins and 5-10 µL of the supernatant were analyzed by ultraperformance liquid chromatography interfaced with either atriple quadrupole (Waters Xevo TQ) or quadrupole time-of-flight(Waters Synapt G2) mass spectrometer. For experiments on fatty
acid oxidation, mice were administered a cocktail containing 150
mg/kg of three fatty acids – palmitic acid, stearic acid, and oleic
acid mixed with intralipid. Experiments were conducted in which
one of the fatty acids was perdeuterated palmitic acid (D31, 98%)
(DLM-215), stearic acid (D35, 98%) (DLM-379), oleic acid (D33, 98%)

(DLM-1891), and the remaining two were unlabeled, or in which
all three fatty acids were perdeuterated. 10 µL of plasma wereincubated with acetone at basic pH to exchange deuteriums in theplasma water with acetone. The deuterium enrichment in acetone
was then measured by headspace gas chromatography interfacedwith an isotope ratio mass spectrometer (Thermo Scientific). Further
details on the methods employed in these experiments can befound in references.6-8

Data Analysis
Total plasma triglycerides were analyzed using a commerciallyavailable biochemical kit (Thermo Scientific). All other data wereacquired and analyzed using the Waters or Thermo instrument
software packages. Multiple-reaction monitoring on a triple
quadrupole mass spectrometer was used to trace the appearanceof oleic acid, potassium salt (13C18, 98%) CP 95% in selected
triglycerides and cholesteryl ester in the blood. The concentrationof 13C18-oleate-labeled lipids was determined from the peak area
ratio of the analyte to its matched, heavy-labeled internal standard.
Concentrations were plotted as a function of time, and the area
under the curve was determined using the Graphpad Prism
software package. Alternatively, data were manually minedfrom full-scan MSe spectra obtained on the quadrupole time-offlight instrument. Selected ion chromatograms were extracted,
and the relative abundance of each 13C18-oleate-labeled lipid
was determined based on the peak area ratio to a class-specificinternal standard.

Results
In particular, we have studied the microsomal triglyceride transfer
protein (MTP), which facilitates the transfer of lipids onto growing
lipoprotein particles in the gut and liver prior to their secretion into
the systemic circulation (Figure 1). Inhibition of MTP prevents
lipidation of these chylomicron and VLDL particles and thereby
prevents lipids from entering the blood. The data presented inContinued ➤Cambridge Isotope Laboratories, Inc.

One of the incessant challenges in mass spectrometry (MS)-based “omics” is the qualification of methods andinstrument platforms. Required are materials that can be used to routinely test platform performance over time
and to test assay effectiveness throughout all phases of a work list.1,2 Such evaluations are necessary as it provides
an indicator to the effectiveness of an analytical method and platform. Errors or deficiencies observed in theperformance would then cue corrective action. This could help save precious samples and experimental resources,
while also extend column lifetimes. Click here to read more.

Analysis of Whole-Body Branched-Chain Amino Acid Metabolism in Mice
Utilizing 20% Leucine 13C6 and 20% Valine 13C5 Mouse Feed
Cancer cells have altered metabolism relative to normal cells. To date, most cancer metabolism research has focusedon understanding the mechanisms of cell autonomous metabolic alterations such as the influence of different
oncogenic signals on nutrient utilization and the effects of altered regulation of specific enzymes on metabolic
fluxes through different pathways (Cairns RA et al. 2011). While these studies have provided insight into metabolic
needs of proliferating cancer cells (Vander Heiden MG et al. 2009), they do not address potential interactions
between tumor and normal tissues. Click here to read more.
