Collection:
| Collection ID: | CO001397 |
| Collection Summary: | Both male and female age-matched C57BL/6 mice (8-10 weeks old) were infected with Mtb H37Rv in animal BSL-3 laboratory and monitored with food and water ad libitum. Mice were sacrificed by anesthesia with isoflurane followed by gentle cervical dislocation as approved by institutional Animal Protocol Number (APN): 08591. Mice experimental procedures were approved by the Institutional Animal Care and Use Committee (IACUC) at the University of Alabama at Birmingham, USA. For mice studies, we adhered as per national/international regulation of “Public Health Service Policy on Humane Care and Use of Laboratory Animals” (NIH), and “Animal Welfare Act and Animal Welfare Regulations” (USDA). Mouse genotype was confirmed by PCR and Western blotting. Mtb H37Rv was grown at 37 °C with shaking in BD Difco Middlebrook 7H9 media supplemented with 0.2 % glycerol, ADS (Albumin, Dextrose, NaCl) with 0.02 % tyloxapol. Mice were infected with 5 x 104 Mtb H37Rv via the intratracheal route. Lungs were collected from uninfected (n = 4), and Mtb-infected mice at 4- and 9-weeks post-infection (n = 4 and n = 5, respectively), and stored immediately at -80 °C for further processing and metabolite extraction. |

| Treatment Summary: | Mice were infected with 5 x 104 Mtb H37Rv via the intratracheal route and zero timepoint and monitored for disease progression until lung collection at 4 or 9 weeks post-infection |
| Treatment: | Infection |
| Treatment Route: | Intratracheal |
| Treatment Dose: | 5 x 10^4 Mtb H37Rv |
Sample Preparation:
| Sampleprep ID: | SP001410 |
| Sampleprep Summary: | After lung collection, 1 mL of 50 % methanol was added to 100 mg of Mtb-infected or uninfected lung tissue and homogenized in a dounce homogenizer to prepare a uniform suspension. For CE-TOF/MS, 200 uL of homogenate were mixed with 200 L of 0.2 M formic acid and vortexed for 2 min. The samples were cleared by centrifugation at 16000 x g for 10 min at 4 °C and the supernatant was filter-sterilized using 0.22 um spin-X columns (Sigma). For GC-QTOF/MS and LC-QTOF/MS, 200 uL of each sample homogenate were mixed with 800 L of 80:20 methanol:MTBE (Methyl tert-butyl ether) and vortexed for 2 min. Metabolites were then extracted for 1 h with shaking at room temperature and then centrifuged at 4000 x g at 20 °C for 20 min. Supernatants were sterile filtered using 0.22 um Spin-X columns. All samples were passed through a Millipore filter (30-kDa cutoff) to remove large proteins. Samples were dried under high vacuum and stored at -80 °C until further platform-specific processing and analysis. For CE-ESI(+)-TOF/MS analysis, The dried samples were resuspended in Milli-Q water containing 0.1 mM formic acid and 0.2 mM methionine sulfone (internal standard) (Sigma-Aldrich, Germany) by vortexing for 1 min. After subsequent centrifugation (12600 x g, 15 min), the resulting clear solution was analyzed. For GC-QTOF/MS analysis, The above described dried samples were re-suspended in 450 µL of MeOH:H2O:MTBE (74:10:16) and after centrifugation at 12600 x g, 15 min at 4 °C, the supernatant was transferred to a vial with insert and evaporated to dryness under high vacuum. The obtained dried extracts were derivatized by a MPS autosampler for GC/MS analysis as previously described (Fiehn O., 2006). For LC-QTOF/MS analysis, The above described dried samples were resuspended in 200 µL of methanol:water:MTBE (7.4:1:1.6), vortexed for 1.5 h and centrifuged (4000 x g, 10 min, 4 °C). Clear solutions were analyzed. |
| Sample Derivatization: | In GC-EI-QTOF/MS analyses, Briefly, aldehyde and keto groups were first converted to O-methyloximes by reaction with 10 µL pyridine containing 15 mg/mL O-methoxyamine (Sigma-Aldrich, Germany) for 60 min at 70 °C. In a second step, acid hydrogen-containing metabolites were trimethylsilylated by reaction with 10 µL N,O-Bis(trimethylsilyl)trifluoroacetamide (BSTFA) (Sigma-Aldrich, Germany) to enhance the GC/MS metabolite coverage |
