Study ID	ST002586
Study Title	Stable isotope tracer analysis (SITA) using 13C6-glucose and 13C5-glutamine measured by GC/MS in BIN-67 cells ± SMARCA4 restoration
Study Summary	SMARCA4/2-loss drives the metabolic shift preferring glutamine than glucose to sustain the TCA cycle. SITA using 13C6-glucose confirmed that glucose uptake was increased in BIN-67 cells upon SMARCA4-restoration, leading to overall increased metabolic flux through glucose (lactate) and TCA cycle intermediates (citrate, fumarate, malate, aspartate) via pyruvate carboxylation.Conversely, the 13C5-glutamine SITA in BIN-67 cells revealed that SMARCA4-restoration decreased glutamine uptake and utilization via glutaminolysis to fuel the TCA cycle as indicated by reduced glutamine metabolites (glutamate, α-KG, m+5 metabolites) and TCA cycle intermediates (succinate, fumarate, malate, aspartate, m+4 metabolites)

Sample Preparation:

Sampleprep ID:	SP002694
Sampleprep Summary:	Cells were washed twice in cold saline solution (NaCl, 0.9 g/l) and metabolites were extracted with 1 ml 80% ice-cold methanol (GC/MS grade). After 2 rounds 10 min sets of sonication (30 seconds on/30 seconds off at high intensity) on slurry ice using a Bioruptor UCD-200 sonicator, the homogenates were centrifuged at 14,000 × g at 4 °C for 10 min. Supernatants were collected and supplemented with internal control (800 ng myristic acid-D27) and dried in a cold vacuum centrifuge (Labconco) overnight. The dried pellets were reconstituted with 30 μL of 10 mg/mL methoxyamine-HCl in pyridine, and incubated for 30 min at room temperature. Samples were then derivatized with MTBSTFA for 30 min at 70 °C. A volume of 1 μL of sample was injected splitless with an inlet temperature of 280 oC into the GC (7890, Agilent)/MS (5975C, Agilent) instrument.
