Study TitleMetabolomics analysis of MMTC/57E or MeAIB treated SNAT2-expressing cells relative to SNAT2-knockout cells or those treated with vehicle.
Study SummaryMetabolite analysis of HY15549 cells expressing a dox-inducible SNAT2 cDNA with deletion of endogenous Snat2 treated with MMTC/57E, MeAIB, or vehicle. Analysis was performed after a total of 24-hours. Each independent experiment was performed on an independent batch of cells. For each experiment, cells were plated with or without doxycycline (0.5 micrograms/mL). After approximately 5-6 hours to allow the cells to attached, the cells were then treated with either MMTC/57E, MeAIB, or vehicle for 18-hours. Metabolites were extracted by adding 1 mL of ice cold 80% methanol containing internal, isotope-labeled amino acid standards. Metabolites were concentrated using a SpeedVac until dry. Metabolites were reconstituted into 50 µL of water, vortexed, centrifuged, and transferred to vials for analysis by LCMS. LCMS was performed using a ZIC-pHILIC LC column coupled to a Vanquish LC and a flow gradient consisting of 10 mM ammonium carbonate in water and pure acetonitrile. The LC was coupled to an Exploris 240 mass spectrometer operated in a polarity switching data-dependent Top 5 mode. Full MS scan parameters for both positive and negative mode were set to 67-1000 m/z at a resolution of 120k and ddMS2 were collected at a resolution of 30k.

Project Title:Metabolomics analysis of SNAT2-deficient cells: implications for the discovery of selective transporter inhibitors
Project Type:Manuscript
Project Summary:Amino acid uptake by the solute carrier family of transporter proteins is critical to support cell metabolism, and inhibition of transporter activity represents a tractable strategy to restrict nutrient availability to cancer cells. A small molecule inhibitor of the sodium-coupled neutral amino acid transporter 2 (SNAT2), 3-(N-methyl(4-methylphenyl)sulfonamido)-N-(2-trifluoromethylbenzyl)thiophene-2-carboxamide (MMTC/57E), was recently identified and was shown to inhibit cell proliferation when combined with glucose transport inhibitors in breast and pancreatic cancer cell lines. In this study, we use mass spectrometry-based metabolomics and establish cell-based assays for the SNAT2 transporter. We show that SNAT2 knockout cells have significant defects in amino acid availability. Using our established assays, we fail to observe that MMTC/57E inhibits SNAT2 activity likely due to its poor solubility.
