| Study ID | ST000033 |
| Study Title | Metabolomics Involved in Early Life Antibiotic Exposures(NOD-Liver) |
| Study Type | Metabolomics |
| Study Summary | In the NOD sub-study, a total of 18 samples from 6 week old, male NOD/ShiLtj mice; comprised of 6 serum samples, 6 cecal content samples and 6 liver tissue samples were analyzed. Three mice/matrix were exposed to PAT and 3 mice/matrix were non-exposed Controls. The mice were housed with SPF (Helicobacter neg/MNV neg) bedding and fed a normal diet. |

| Project Title: | Metabolomics Involved in Early Life Antibiotic Exposures |
| Project Type: | Obesity modeling of antibiotic exposure |
| Project Summary: | The project Metabolomics Involved in Early Life Antibiotic Exposures profiled a total of 90 samples from five sub-studies (DuraSTAT, TranSTAT, NOD, EstroSTAT and VG STAT) which included a total of four sample matrices (urine, serum, liver tissue and cecal contents). Within each sub-study, there were three sample matrices except for VG STAT, for which there was only two. For each matrix type within each sub-study 6 samples were analyzed for a total of 18 samples per sub-study (9 of each in VG STAT), the samples were equally divided into STAT/PAT-treated (sub-therapeutic antibiotic treatment (STAT) and therapeutic dose-pulsed antibiotic treatment (PAT)) collected at various time-points versus untreated Controls for each matrix. |

Sample Preparation:
| Sampleprep ID: | SP000046 |
| Sampleprep Summary: | Frozen liver samples were weighed (50-100 mg) into labeled homogenizer bead tubes. Cold acetonitrile:water (50%) was added to tissue based on weight to make 1 mg/mL homogenates. The samples were extracted and homogenized on a Spex Geno/Grinder for two 45 second pulses at 1750 rpm. Samples were centrifuged at 12000 rcf for 5 min. Liver supernatants were transferred into BSI-labeled tubes. A 500 μL aliquot/sample was transferred into a second set of BSI-labeled tubes for further processing. To make pooled samples, a 300 μL aliquot of selected TranSTAT liver supernatants was combined in a 2 mL tube and used for QC samples in DuraSTAT, TranSTAT, EstroSTAT and NOD sub-studies. Additionally, a 200 μL aliquot of selected VG STAT liver supernatants was combined in a separate 2 mL tube and used as QC samples in the VG STAT sub-study. Three 500 μL aliquots were transferred into BSI-labeled tubes for each set of Pooled QC samples. All samples were then dried on an Eppendorf rotaVap (V-AL setting) at 30°C until dry and stored at -80 °C. On the second day of processing, 630 μL of D2O was added into each dried liver extract tube. Chenomx Internal Standard solution (Chenomx ISTD, Edmonton, Alberta, Canada) contains 5mM 4,4-dimethyl-4-silapentane-1-sulfonic acid (DSS, Chemical Shift Indicator), 100 mM Imidazole (pH indicator), and 0.2% NaN3 (to inhibit bacterial growth) was added (70 µl), and the samples were vortexed on a multi-tube vortexer for 10 minutes at speed 5. Tubes were then centrifuged at 12000 rcf for 5 minutes and a 600 μL aliquot of the supernatant was transferred into 5mm NMR tubes (Wilmad LabGlass, New Jersey, USA) which were kept on ice until data acquisition. |
