Study TitleMetabolic effect of the loss of mitochondrial-specific aspartyl-tRNA synthetase Das2 on mouse intestinal epithelial cells
Study SummaryWe analysed the intestinal epithelial cell (IEC) from Dars2 fl/fl ; VillinCreERT2 tg/wt mice (n=15) and and Dars2 fl/fl ; VillinCreERT2 wt/wt mice (n=9) at 8 days upon tamoxifen injection to assess the metabolic effect of Das2 loss. Isolated IECs were divided into three technical replicates (n=69) and analysed with two analytical repeats (n=138).

MS Type:ESI
MS Comments:Metabolites were measured with a Thermo Scientific Q Exactive Hybrid Quadrupole-Orbitrap Mass spectrometer (HRMS) coupled to a Dionex Ultimate 3000 UHPLC. The mass spectrometer was operated in full-scan, polarity-switching mode, with the spray voltage set to +4.5 kV/-3.5 kV, ion transfer tube temperature set to 320 °C, the vaporizer temperature set to 280 °C, the sheath gas flow set to 55 units, the auxiliary gas flow set to 15 units, and the sweep gas flow set to 0 unit. HRMS data acquisition was performed in a range of m/z = 70–900, with the resolution set at 70,000, the AGC target at 1 × 106, and the maximum injection time (Max IT) at 120 ms. Chromatogram review and peak area integration were performed using the Thermo Fisher software Tracefinder (v.5.0). Metabolite identities were confirmed using two parameters: (1) precursor ion m/z was matched within 5 ppm of theoretical mass predicted by the chemical formula; (2) the retention time of metabolites was within 5% of the retention time of a purified standard run with the same chromatographic method.
