PR:PROJECT_TITLE                 	Mayo Pilot and Feasibility: Identifying metabolic adaptations characteristic of
PR:PROJECT_TITLE                 	multiple myeloma cells via mass spectrometry-based metabolite profiling
PR:PROJECT_SUMMARY               	Multiple myeloma (MM) is a clonal plasma cell malignancy that remains incurable
PR:PROJECT_SUMMARY               	in most afflicted patients. It can be preceded by an asymptomatic, premalignant
PR:PROJECT_SUMMARY               	stage known as smoldering multiple myeloma (SMM) that does not require therapy
PR:PROJECT_SUMMARY               	but has an increased life-long risk of progression to MM. However, one-third of
PR:PROJECT_SUMMARY               	SMM patients are “high risk” for imminent progression to MM within two years
PR:PROJECT_SUMMARY               	of diagnosis compared to the remainder of SMM patients who continue on an
PR:PROJECT_SUMMARY               	indolent asymptomatic course for several years. The diagnosis of MM cannot be
PR:PROJECT_SUMMARY               	made until they experience overt end-organ damage such as renal failure, lytic
PR:PROJECT_SUMMARY               	bone destruction, anemia and hypercalcemia. Currently, we lack sensitive
PR:PROJECT_SUMMARY               	biomarkers that can identify all SMM patients at high risk of progression to MM.
PR:PROJECT_SUMMARY               	Being able to identify high risk SMM patients could allow us to initiate
PR:PROJECT_SUMMARY               	systemic chemotherapy before they progress to MM. Cancer cells undergo distinct
PR:PROJECT_SUMMARY               	metabolic adaptations to meet the augmented cellular demand for energy and
PR:PROJECT_SUMMARY               	nutrients created by their increased rates of cellular proliferation. The
PR:PROJECT_SUMMARY               	presence of an altered cellular metabolism in clonal PCs from MM patients and
PR:PROJECT_SUMMARY               	its role as an essential factor in the progression of SMM to MM is unknown. We
PR:PROJECT_SUMMARY               	hypothesize that the clonal PCs in high risk SMM patients likely have an altered
PR:PROJECT_SUMMARY               	metabolic phenotype similar to those present in MM patients but different when
PR:PROJECT_SUMMARY               	compared to clonal PCs in the remainder of the SMM patients whose clinical
PR:PROJECT_SUMMARY               	course remains indolent. Thus, two specific aims are proposed in this study: Aim
PR:PROJECT_SUMMARY               	1 will verify if there are differences in the regulation of the metabolic
PR:PROJECT_SUMMARY               	pathways in clonal PCs from MM patients compared to normal PCs from healthy
PR:PROJECT_SUMMARY               	patients; Aim 2 will assess whether the clonal PCs from high risk SMM patients
PR:PROJECT_SUMMARY               	bear a distinct metabolic phenotype compared to clonal PCs from standard risk
PR:PROJECT_SUMMARY               	SMM patients.

#COLLECTION
CO:COLLECTION_SUMMARY            	"In order to analyze the metabolites of clonal PCs (intracellular) and BM plasma
CO:COLLECTION_SUMMARY            	(extracellular) separately, they have to be separated out from the BM samples.
CO:COLLECTION_SUMMARY            	Thus, upon acquiring the BM samples from patients they will be placed in
CO:COLLECTION_SUMMARY            	centrifuged at 2500 rpm for 10 minutes to separate out the plasma from the
CO:COLLECTION_SUMMARY            	cellular fraction. The separated BM plasma is then stored in separate vials and
CO:COLLECTION_SUMMARY            	snap frozen under liquid nitrogen for 20 seconds before storing at -80οC for
CO:COLLECTION_SUMMARY            	further analysis. The leftover cellular component present as a pellet will be
CO:COLLECTION_SUMMARY            	washed and reconstituted with an equal volume of RPMI 1640 medium. Erythrocytes
CO:COLLECTION_SUMMARY            	are lysed using ammonium chloride lysing solution. After incubation on ice for 5
CO:COLLECTION_SUMMARY            	min, the cell suspension is diluted with RPMI medium. The cells are again
CO:COLLECTION_SUMMARY            	pelleted by centrifugation and then suspended in RoboSep buffer (250ml PBS, 2%
CO:COLLECTION_SUMMARY            	BSA, 1mM EDTA). The clonal CD138 positive PCs are purified using positive
CO:COLLECTION_SUMMARY            	selection by mixing the cells with a CD138 positive selection cocktail and

CO:COLLECTION_SUMMARY            	separation system, StemCell Technologies Inc) in the automated RoboSep cell

CO:COLLECTION_SUMMARY            	re‐suspended and then centrifuged to form a cell pellet. The goal will be to
CO:COLLECTION_SUMMARY            	obtain at least 1-2 x 107 clonal PCs per sample. The cell pellet will be snap
CO:COLLECTION_SUMMARY            	frozen under liquid nitrogen for 20 seconds before storing at -80οC for further
CO:COLLECTION_SUMMARY            	analysis. Both the BM plasma samples as well as the clonal PCs pellet will be
CO:COLLECTION_SUMMARY            	provided to the metabolomics core for sample preparation for LC-MS analysis. For
CO:COLLECTION_SUMMARY            	Aim 2, we will be using stored BM samples from SMM patients that have already
CO:COLLECTION_SUMMARY            	had their BM plasma and clonal PCs separated from each other and stored at
CO:COLLECTION_SUMMARY            	-80οC. It is important to note that all these samples were collected and frozen
CO:COLLECTION_SUMMARY            	in a timely manner. Furthermore consistency in sample collection, storage and
CO:COLLECTION_SUMMARY            	processing is imperative for the optimal conduct of metabolomics-based
CO:COLLECTION_SUMMARY            	experiments. This ensures that all samples being analyzed and compared with each
CO:COLLECTION_SUMMARY            	other would have been manipulated similarly, limiting any handling biases. All
CO:COLLECTION_SUMMARY            	patient samples in the Predolin Foundation Biobank were collected and stored by
CO:COLLECTION_SUMMARY            	following a standardized operating procedure. BM samples were processed for BM
CO:COLLECTION_SUMMARY            	plasma separation and clonal PCs enrichment but were then immediately snap
CO:COLLECTION_SUMMARY            	frozen for storage at -80οC within approximately 3 hours of collection from the
CO:COLLECTION_SUMMARY            	patient. All samples were collected in patients who have been fasting for at
CO:COLLECTION_SUMMARY            	least 6 to 8 hours prior. To further ensure consistency in our analysis of this
CO:COLLECTION_SUMMARY            	study, we will only use samples that have never been thawed since initial
CO:COLLECTION_SUMMARY            	storage to preserve the stability of the metabolites originally present in the
CO:COLLECTION_SUMMARY            	samples."
#TREATMENT
TR:TREATMENT_SUMMARY             	We will use matched BM plasma and purified clonal marrow PCs from the BM samples
TR:TREATMENT_SUMMARY             	of SMM patients collected at the time of their diagnosis and stored within the
TR:TREATMENT_SUMMARY             	Mayo Clinic Predolin Foundation Biobank. We will select BM samples from patients
TR:TREATMENT_SUMMARY             	with SMM who progressed to MM within 2 years of their samples being collected
TR:TREATMENT_SUMMARY             	and stored; this will constitute the high risk SMM group. We will also select BM
TR:TREATMENT_SUMMARY             	samples from SMM patients who have not progressed to MM within at least 2 years
TR:TREATMENT_SUMMARY             	of follow up of their samples being collected and stored; this will constitute
TR:TREATMENT_SUMMARY             	the standard risk SMM group. The strength of this approach is that we will
TR:TREATMENT_SUMMARY             	utilize stored SMM samples from one of the most comprehensively characterized
TR:TREATMENT_SUMMARY             	monoclonal gammopathy biobanks available. Secondly, all samples will be obtained
TR:TREATMENT_SUMMARY             	from collection dates at least 2 years prior in order to ensure adequate
TR:TREATMENT_SUMMARY             	follow-up time to assess their current clinical status. This would avoid the
TR:TREATMENT_SUMMARY             	need to prospectively collect samples from SMM patients and clinically follow
TR:TREATMENT_SUMMARY             	them for a number of years before we are able to gauge who were clinically high
TR:TREATMENT_SUMMARY             	or standard risk for progression. There are over 700 SMM patients who have had
TR:TREATMENT_SUMMARY             	their BM samples collected and stored in the biobank from 1996 to 2013; more
TR:TREATMENT_SUMMARY             	than half these patients have progressed to MM.
#SAMPLEPREP
SP:SAMPLEPREP_SUMMARY            	The metabolite profiling as well as sample preparations will be undertaken at
SP:SAMPLEPREP_SUMMARY            	the Mayo Clinic Metabolomics Resource Core. The matched BM plasma and clonal PCs
SP:SAMPLEPREP_SUMMARY            	pellets from the stored patient samples will undergo metabolite extraction and
SP:SAMPLEPREP_SUMMARY            	analysis by LC-MS. They will be deproteinized with cold methanol (1:4 ratio) and
SP:SAMPLEPREP_SUMMARY            	centrifuged at 15,000 g for 20 minutes at 4οC. The supernatants will be divided
SP:SAMPLEPREP_SUMMARY            	into 2 aliquots and dried down under a stream of nitrogen for 90 minutes and
SP:SAMPLEPREP_SUMMARY            	stored at -20C until ready for analysis. These samples will undergo preparation
SP:SAMPLEPREP_SUMMARY            	for metabolite separation and analysis on a Time-of-Flight (TOF) Mass
SP:SAMPLEPREP_SUMMARY            	Spectrometer (Agilent Technologies 6220 TOF) coupled with an Ultra High Pressure
SP:SAMPLEPREP_SUMMARY            	Liquid Chromatograph (Waters Acquity). The dried metabolites will be
SP:SAMPLEPREP_SUMMARY            	re‐suspended in H2O/acetonitrile solution containing injection standards.
SP:SAMPLEPREP_SUMMARY            	Profiling data will be acquired under both positive and negative electrospray
SP:SAMPLEPREP_SUMMARY            	ionization modes separately over a scan range of 50 - 1200 m/z at a resolution
SP:SAMPLEPREP_SUMMARY            	of 10,000. Metabolite separation will be achieved using two columns of differing
SP:SAMPLEPREP_SUMMARY            	polarity, a hydrophilic interaction column (HILIC, ethylene-bridged hybrid 2.1 x
SP:SAMPLEPREP_SUMMARY            	150 mm, 1.7 mm; Waters) and a reversed-phase C18 column (high-strength silica
SP:SAMPLEPREP_SUMMARY            	2.1 x 150 mm, 1.8 mm; Waters). For positive ion detection, mobile phase A will
SP:SAMPLEPREP_SUMMARY            	contain 100% water with 0.1% formic acid and mobile phase B will contain 100%
SP:SAMPLEPREP_SUMMARY            	methanol with 0.1% formic acid. For negative ion detection, formic acid will be
SP:SAMPLEPREP_SUMMARY            	replaced with 0.1% ammonium bicarbonate. For each column, the run time will be
SP:SAMPLEPREP_SUMMARY            	20 min using a flow rate of 400 microL/min. A total of four runs per sample will
SP:SAMPLEPREP_SUMMARY            	be performed to give maximum coverage of metabolites. Samples will be injected
SP:SAMPLEPREP_SUMMARY            	in triplicate with blank injections between samples. Quality control samples,
SP:SAMPLEPREP_SUMMARY            	made up of a subset of samples from the study will be injected several times
SP:SAMPLEPREP_SUMMARY            	during a run.
