Briefly, 5 L of biofluid samples or serial dilutions of a chemical standard library of 149 metabolites were extracted with 45 L of a 75:25:0.1 HPLC grade acetonitrile:methanol:formic acid extraction mix that included the following labeled stable isotope internal standards: 13 C-labeled yeast extract (Cambridge Isotope Laboratory, Andover, MA, ISO1), 2 H 9 choline (Cambridge Isotope Laboratory, Andover, MA, DLM-549), 13 C 4 3-hydroxybutyrate (Cambridge Isotope Laboratory, Andover, MA, CLM-3853), 13 C 6 15 N 2 cystine (Cambridge Isotope Laboratory, Andover, MA, CNLM4244), 13 C 3 lactate (Sigma-Aldrich, Darmstadt, Germany, 485926), 13 C 6 glucose (Cambridge Isotope Laboratory, Andover, MA, CLM-1396), 13 C 3 serine (Cambridge Isotope Laboratory, Andover, MA, CLM-1574), 13 C 2 glycine (Cambridge Isotope Laboratory, Andover, MA, CLM-1017), 13 C 5 hypoxanthine (Cambridge Isotope Laboratory, Andover, MA, CLM8042), 13 C 2 15 N taurine (Cambridge Isotope Laboratory, Andover, MA, CNLM-10253), 13 C 3 glycerol (Cambridge Isotope Laboratory, Andover, MA, CLM-1510) and 2 H 3 creatinine (Cambridge Isotope Laboratory, Andover, MA, DLM-3653)
Importantly, flow cytometric analysis of MZB both excluded any gene-dosage effect of Gclc expression and confirmed that loss of MZB was independent of any Cre -associated toxicity (Supplementary Fig
