| Study Title | NRF2 supports non-small cell lung cancer growth independently of CBP/p300-enhanced glutathione synthesis: Global metabolomics analysis on A549 cells at different NRF2 status (Part 1 of 3) |
| Study Type | Untargeted Metabolomics |
| Study Summary | This study aims at discovering metabolic changes in A549 cancer cells in the presence and absence of NRF2, and a mutant NRF2 genotypes. Metabolites were extracted from cell pellets by using an LLE method with Methanol/Chloroform/water. The aqueous layer was analyzed by HILIC-HRMS. An in-house RT library was used to identify metabolites. Statistical analyses was performed to identify statistically significant changes in the metabolism. 35 metabolites presented differential abundance between NRF2 knockdown and wildtype conditions. In particular, GSH and several glutamate dipeptides were significantly depleted upon NRF2 knockdown, in line with the prevailing role of NRF2 in controlling GSH biosynthesis. Disruption of additional metabolites involved in the PPP (sedoheptulose-7-phosphate, S7P), nucleotide (CMP, IMP) and amino acid (kynurenine, homocitrulline) metabolism were also observed upon NRF2 knockdown. |
