Study ID	ST003826
Study Title	Polar metabolite profiling of TTM-treated SEM cells
Study Summary	To investigate the effects of ammonium tetrathiomolybdate (TTM) (a copper chelator) on steady state metabolite levels, SEM cells were treated for 2, 6 or 24 hours with 100uM TTM; control cells received DMSO for 2 hours. This experiment revealed that TTM treatment significantly perturbed nucleotide levels.

Project Title:	In vivo CRISPR screen identifies copper metabolism as a vulnerability in acute lymphoblastic leukemia
Project Summary:	The nutrient-sparse cerebrospinal fluid (CSF) poses a significant challenge to spreading cancer cells. Despite this challenge, leukemia often spreads to the CSF and represents a significant clinical complication. To uncover nutritional dependencies of leukemia cells in the CSF that could be targeted therapeutically, we conducted an in vivo targeted CRISPR screen in a xenograft model of leukemia. We found that SLC31A1, the primary cell surface copper importer, is a genetic dependency of leukemia in both the central nervous system as well as in the hematopoietic organs. Perturbation of copper metabolism leads to complex IV deficiency, perturbed nucleotide metabolism and slowed leukemia cell proliferation. Furthermore, nutritional copper depletion reduced cancer progression in cell line based and patient-derived xenograft models of leukemia. Copper thus appears to be an actionable micronutrient in leukemia.

Collection:

Collection ID:	CO004630
Collection Summary:	One and a half million cells from culture were collected via centrifugation for 20 seconds at 18,000xG at 4C, washed once with ice-cold 0.9% NaCl, and collected via centrifugation for 20 seconds at 18,000xG at 4C. Cells were cultured in RPMI-1640 with 10% FBS and penicillin/streptomycin in a 37C incubator with 5% CO2.
Sample Type:	Leukemia cells

Treatment:

Treatment ID:	TR004646
Treatment Summary:	Cells were treated for up to 24 hours with vehicel (DMSO) or 100uM TTM. Culture media was RPMI-1640 containing 10% FBS and penicillin and streptomycin in 6-well plates. Cells were seeded at 1.5 million/mL in 4mL.

Sample Preparation:

Sampleprep ID:	SP004643
Sampleprep Summary:	Cell pellet was resuspended in 400uL of 100% LC-MS grade methanol supplemented with isotopically-labelled amino acid standards [Cambridge Isotope Laboratories, MSK-A2-1.2], aminopterin, and reduced glutathione standard [Cambridge Isotope Laboratories, CNLM-6245-10]). with repeated pipetting up and down and vortexing for 10 seconds. Then, 100uL of LCMS-grade water containing 125 mM Ammonium Acetate, 10 mM Na-Ascorbate, and 7.9 mg/mL 5,5-dithio-bis-(2-nitrobenzoic acid (Ellman's reagent) was added, and the sample vortex for another 10 seconds. Samples were then centrifuged for 10 minutes at 18,000 g to pellet cell debris. The supernatant was transferred to a new tube and dried on ice using a liquid nitrogen dryer. The dried metabolites were then resuspended in 30uL and 2uL was injected.

Instrument Name:	Thermo Q Exactive Orbitrap
Instrument Type:	Orbitrap
MS Type:	ESI
MS Comments:	MS data acquisition was performed using a QExactive benchtop orbitrap mass spectrometer equipped with an Ion Max source and a HESI II probe (Thermo Fisher Scientific) and polarity switching was used. Four scans were used: full scans in both positive and negative ionization mode in a range of m/z = 70–1000, with the resolution set at 70,000, the AGC target at 1 × 10e6, and the maximum injection time (Max IT) at 20 msec from 0-20 minutes. A third scan in the negative mode was used with range of m/z = 220-700 from 0-20 minutes and the same resolution, AGC settings with 30ms Max IT. Lastly, a targeted-SIM scan was added with a resolution of 35k, AGC target 1e5, and max IT 20ms, isolation window = 1.0 m/z, with an inclusion m/z of 503.0552 (corresponding to Ellman-derivatized glutathione). Tune file parameters were: spray voltage = 3.5kV, capillary temperature = 320C, S-lens RF = 50, auxillary gas temperature = 350C.
