Collection:
| Collection ID: | CO003179 |
| Collection Summary: | AGS cells or AZ-521 cells were cultured in Roswell Park Memorial Institute (RPMI) 1640 medium containing 10% fetal bovine serum, or minimal essential medium (MEM) containing 10% fetal bovine serum and 5% nonessential amino acids, respectively. |

| Storage Conditions: | -80℃ |
Treatment:
| Treatment ID: | TR003195 |
| Treatment Summary: | AGS and AZ-521 cells were cultured in T-75 cell culture flasks overnight to a density of approximately 4x106 cells. Cells were incubated in media containing 20 ug/mL of purified s1m1 VacA toxin and 5 mM ammonium chloride, and supplemented with 10mM Taurine. Following intoxication, the media was removed, and cells were washed with PBS. Cells were detached by incubation with trypsin for 5 minutes and collected via centrifugation at 4°C at 1,000 rpm for 4 minutes. Trypsin was removed, cells were once again washed with PBS, and the cells were then flash-frozen in liquid nitrogen and stored at -70°C. |

Sample Preparation:
| Sampleprep ID: | SP003192 |
| Sampleprep Summary: | Samples were analyzed via Liquid Chromatography-High Resolution Mass Spectrometry (LC-HRMS and LC-HRMS/MS)-based metabolomics using previously described methods26,27,28. Briefly, cell pellets were normalized by total protein (200 ug) and the corresponding cell supernatants were normalized by volume (200 uL). Metabolites were extracted with methanol/water 80:20. Heavy labeled phenylalanine-D8 and biotin-D2 were added to individual samples prior to protein precipitation. Following overnight incubation at -80°C, precipitated proteins were pelleted by centrifugation at 10,000 rpm for 10 min and metabolite extracts were transferred into two Eppendorf tubes in equal amounts and dried down in vacuo and stored at -80°C. |
