Therefore, PR:PROJECT_SUMMARY knowledge of microenvironmental nutrient levels and how cancer cells cope with PR:PROJECT_SUMMARY such nutrition is critical to understand the metabolism underpinning cancer cell PR:PROJECT_SUMMARY biology. Previously, we performed quantitative metabolomics of the interstitial PR:PROJECT_SUMMARY fluid (the local perfusate) of murine pancreatic ductal adenocarcinoma (PDAC) PR:PROJECT_SUMMARY tumors to comprehensively characterize nutrient availability in the PR:PROJECT_SUMMARY microenvironment of these tumors (Sullivan et al., 2019a). Here, we develop PR:PROJECT_SUMMARY Tumor Interstitial Fluid Medium (TIFM), a cell culture medium that contains PR:PROJECT_SUMMARY nutrient levels representative of the PDAC microenvironment, enabling study of PR:PROJECT_SUMMARY PDAC metabolism under physiological nutrition. We show that PDAC cells cultured PR:PROJECT_SUMMARY in TIFM, compared to standard laboratory models, adopt a cellular state more PR:PROJECT_SUMMARY similar to PDAC cells in tumors. Further, using the TIFM model we identified PR:PROJECT_SUMMARY arginine biosynthesis as a metabolic adaptation PDAC cells engage to cope with PR:PROJECT_SUMMARY microenvironmental arginine starvation driven by myeloid cells in PDAC tumors. PR:PROJECT_SUMMARY Altogether, these data show that nutrient availability in tumors is an important PR:PROJECT_SUMMARY determinant of cancer cell metabolism and behavior, and cell culture models that PR:PROJECT_SUMMARY incorporate physiological nutrient availability have improved fidelity and PR:PROJECT_SUMMARY enable the discovery of novel cancer metabolic phenotypes.

We also tested this with pharmacological inhibition of arginase-1 ST:STUDY_SUMMARY with the small-molecule inhibitor CB-1158. We then isolated IF from these tumors ST:STUDY_SUMMARY at end-stage and measured the levels of amino acids including arginine and ST:STUDY_SUMMARY ornithine in these samples.

Tumors were weighed and CO:COLLECTION_SUMMARY rinsed in blood bank saline solution (150 mM NaCl) and blotted on filter paper CO:COLLECTION_SUMMARY (VWR, Radnor, PA, 28298–020). The process of dissection and tumor preparation CO:COLLECTION_SUMMARY took < 3min. Tumors were cut in half and put onto 20µm nylon mesh filters CO:COLLECTION_SUMMARY (Spectrum Labs, Waltham, MA, 148134) on top of 50 mL conical tubes, and CO:COLLECTION_SUMMARY centrifuged for 10min. at 4°C at 400xg. IF was then collected, snap-frozen in CO:COLLECTION_SUMMARY liquid nitrogen and stored at -80°C until further analysis. CO:SAMPLE_TYPE Interstitial Fluid #TREATMENT TR:TREATMENT_SUMMARY For genetically modified mice, LysM-Cre and Arg1fl/fl C57BL6J mice were bred to TR:TREATMENT_SUMMARY generate LysM-Cre +/+; Arg1fl/fl and litter mate control Arg1fl/fl mice. TR:TREATMENT_SUMMARY Orthotopic pancreatic cancer tumors were implanted in C57BL6J mice at 8-12 weeks TR:TREATMENT_SUMMARY of age. At endpoint, mice were euthanized by cervical dislocation, and tumors TR:TREATMENT_SUMMARY were harvested for TIF extraction. For Pharmacological inhibition, orthotopic TR:TREATMENT_SUMMARY tumors were implanted in C57BL6J mice at 8-12 weeks of age. 4 weeks after TR:TREATMENT_SUMMARY induction, once tumors were close end stage disease, CB-1158 (MedChem Express) TR:TREATMENT_SUMMARY dissolved in sterile water was administered by oral gavage at 100mg/kg. The TR:TREATMENT_SUMMARY acidity caused by the HCl in the drug solution was neutralized by adding TR:TREATMENT_SUMMARY equivalent amount of NaOH and an equivalent NaCl in sterile water solution was TR:TREATMENT_SUMMARY prepared as vehicle. 2hrs after treatment with CB-1158 or vehicle, mice were TR:TREATMENT_SUMMARY euthanized by cervical dislocation, and tumors were harvested for TIF TR:TREATMENT_SUMMARY extraction. #SAMPLEPREP SP:SAMPLEPREP_SUMMARY polar metabolites were extracted from 5µL IF samples using 45µL 75:25:0.1 HPLC SP:SAMPLEPREP_SUMMARY grade acetonitrile:methanol:formic acid extraction mix into which a mixture of SP:SAMPLEPREP_SUMMARY isotopically labeled amino acids of known concentrations (Cambridge Isotope SP:SAMPLEPREP_SUMMARY Laboratories, MSK-A2-1.2) was added. Samples were vortexed for 10 min, and SP:SAMPLEPREP_SUMMARY centrifuged at maximum speed for 10 min. 30 μL of each extract was removed and SP:SAMPLEPREP_SUMMARY dried under nitrogen gas and stored −80°C. #CHROMATOGRAPHY CH:CHROMATOGRAPHY_TYPE HILIC CH:INSTRUMENT_NAME Thermo Dionex Ultimate 3000 CH:COLUMN_NAME Waters XBridge Amide (100 x 4.6mm,3.5um) CH:SOLVENT_A 95% (vol/vol) water, 5% (vol/vol) acetonitrile, 10 mM ammonium hydroxide, 10 mM CH:SOLVENT_A ammonium acetate, pH = 9.0 CH:SOLVENT_B 100% Acetonitrile CH:FLOW_GRADIENT 0 min, 15% A; 2.5 min, 64% A; 12.4 min, 40% A; 12.5 min, 30% A; 12.5-14 min, 30% CH:FLOW_GRADIENT A; 14-21 min, 15% A CH:FLOW_RATE 150 μL/min CH:COLUMN_TEMPERATURE 25 #ANALYSIS AN:ANALYSIS_TYPE MS #MS MS:INSTRUMENT_NAME Thermo Q Exactive Orbitrap MS:INSTRUMENT_TYPE Orbitrap MS:MS_TYPE ESI MS:ION_MODE UNSPECIFIED MS:MS_COMMENTS In positive/negative polarity switching mode, an m/z scan range from 60 to 900 MS:MS_COMMENTS was chosen and MS1 data was collected at a resolution of 70,000. The automatic MS:MS_COMMENTS gain control (AGC) target was set at 1 × 106 and the maximum injection time was MS:MS_COMMENTS 200 ms. The targeted ions were subsequently fragmented, using the higher MS:MS_COMMENTS energy collisional dissociation (HCD) cell set to 30% normalized collision MS:MS_COMMENTS energy in MS2 at a resolution power of 17,500. Besides matching m/z, target MS:MS_COMMENTS metabolites are identified by matching either retention time with analytical MS:MS_COMMENTS standards and/or MS2 fragmentation pattern. Data acquisition and analysis were MS:MS_COMMENTS carried out by Xcalibur 4.1 software and Tracefinder 4.1 software, respectively MS:MS_COMMENTS (both from Thermo Fisher Scientific).
