Collection:
Collection ID: | CO001510 |
Collection Summary: | 7 control fibroblasts samples and 7 patient-derived fibroblasts samples were collected at day 0 and day 5. Intracellular metabolites were extracted from cells cultured in 6 well plate while acyl-CoA and 5-methyltetrahydrofolate were extracted from cells cultured in 60 mm dish. Intracellular metabolites and acyl-CoA from cells were harvested as described previously using 80% methanol/water as solvent (PMID: 24410464, PMID: 24894601, PMID: 25795660) and dry pellets were stored in -80 °C freezer until ready for LC-MS analysis. For acyl-CoA and 5-methyltetrahydrofolate analysis, dry pellets were reconstituted into 30 μL of sample solvent (water containing 50 mM ammonium acetate), and 10 μL was injected into the LC-MS. For non-acyl-CoA polar metabolite analysis, pellets were reconstituted into 30 μL of sample solvent (water:methanol:acetonitrile, 2:1:1, v/v), and 3 μL was injected into the LC-MS. |
Sample Type: | Cultured fibroblasts |
Treatment:
Treatment ID: | TR001530 |
Treatment Summary: | Patient-derived fibroblasts cultured in standard culture conditions (proliferative condition) and cells cultured for 5 days in low-serum conditions (non-proliferative condition). Patients carry disease-causing mutations in SUCLA2. Controls are fibroblasts from age-matched patients with other mitochondrial diseases. |
