| Study Title | Metabolomics analysis of Glioblastoma (GBM) cell line U251 labeled by 13C-glutamine after treatment with pimozide |
| Study Summary | Glioblastoma (GBM) cell line U251 was treated with antipsychotic drug pimozide (3 uM) for 24 hr, and then labeled with 13C-glutamine (2 mM) for 1 hr. Cells were collected and extracted for metabolites and analyzed by LC-MS. Our data showed that pimozide treatment significantly increased 13C-labeled glutamine uptake and subsequent consumption, including anaplerosis of metabolites for tricarboxylic acid (TCA) cycle and de novo fatty acid synthesis derived from glutamine-mediated reductive carboxylation process. |

Sample Preparation:
| Sampleprep ID: | SP003490 |
| Sampleprep Summary: | After treatment, the cells were washed twice with cold PBS and quenched with cold acetonitrile and ultrapure water (4:3, v:v) for 5 min. Metabolites were then extracted for subsequent LC-MS analysis. |
