| Study Title | Polar metabolite profiling of BCS-treated SEM cells with or without rescue with copper (ii) chloride and 15N-amide-glutamine tracing |
| Study Summary | To investigate the effects of bathocuproinedisulfonic acid (BCS) treatment (a copper chelator) on nucleotide synthesis, SEM cells were treated for 14 days with vehicle, 50uM BCS, 50uM CuCl2, or 50uM of both. Cells were seeded at 0.25 million/mL and counted and passaged every two days. On day 12, cells were also conditioned with media containing dialyzed FBS. On day 14, cells were seeded at 1.5 million/mL in glutamine-free RPMI-1640 with 15N-amide glutamine added back for 4 hours, then subjected to polar metabolomics. This experiment revealed that copper depletion with BCS lead to increased label incorporation and increased abundance of carbamoyl aspartic acid, and reduced label incorporation into purine and pyrimidine nucleotide mono, di and triphosphates. |

| 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. |

| 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. |
