| Study Title | Metabolomics analysis of ALDH1L1-expressing HuH7 cell lines. |
| Study Summary | One-carbon metabolism is utilized for the de novo synthesis of purines. Given that tumor cells require large amounts of nucleotides, they are highly dependent on one-carbon metabolism. Among the one-carbon-metabolizing enzymes, the aldehyde dehydrogenase 1 family member L1 (ALDH1L1), which catalyzes 10-formyltetrahydrofolate to tetrahydrofolate, is considered a tumor suppressor gene, as its expression is reported to be attenuated or diminished in hepatocellular carcinoma. To clarify the effect of ALDH1L1 expression, we generated control and ALDH1L1-expressing HuH-7 (H7-1L1) cells, and measured the amounts of intracellular metabolites in both control and ALDH1L1-expressing by CE-TOFMS analysis. |

| MS Comments: | The spectrometer was scanned from m/z 50 to 1,000. Peaks were extracted using automatic integration software MasterHands (ver.2.16.0.15 Keio University). Signal peaks corresponding to isotopomers, adduct ions, and other product ions of known metabolites were excluded, and remaining peaks were annotated with putative metabolites from the HMT metabolite database based on their migration time and m/z values. Peak areas were normalized to internal standards and sample amounts. |
