Sampleprep Summary: | The metabolomic sample preparation method was: The tissue samples were ground into a homogenous powder with a Retsch Cryomill (Retsch-Allee, Haan, Germany). 45 – 80 mg of the pulverized sample was weighed and stored in the -80 oC freezer prior to extraction. Samples were allowed to thaw at 4 °C for 30 min before adding 1.5 mL of 20:40:40 water/methanol/acetonitrile with 0.1 M formic acid for metabolites extraction. The samples were vortexed and centrifuged and the supernatants were isolated and dried completely under nitrogen. The dried samples were resuspended in 300 µL water and an aliquot were transferred to autosampler vials for UHPLC-HRMS analysis. Mass analysis was carried out at the University of Tennessee Biological and Small Molecule Mass Spectrometry Core (RRID: SCR_021368) using an UltiMate 3000 liquid chromatography system (Dionex, Sunnyvale, CA, USA) coupled to an Exactive Plus Orbitrap mass spectrometer (Thermo Fisher Scientific, Waltham, MA). |
