| Collection Summary: | Metabolite extraction was carried out as previously described (96). Briefly, ~20-30 mg of kidney cortex was homogenized under cryogenic conditions in cryomill tubes containing beads for homogenization (Precellys bead-mill with a Cryolys attachment, Bertin Technologies, France) and 600 mL of 3:1 methanol:water (v/v) containing 0.5 nmol 13C6-sorbitol and 5 nmol 13C5,15N-valine as internal standards. Homogenates (480 mL) were subsequently vortexed in fresh Eppendorf tubes containing 120 ml chloroform. The resultant extracts were centrifuged to pellet cell debris and precipitated protein. The supernatant was used for subsequent analysis. In addition, an aliquot from each sample was pooled and re-aliquoted to generate pooled biological quality controls (PBQC). Samples and PBQCs were evaporated dry by speed vacuum centrifugation and then derivatized online using the Shimadzu AOC6000 autosampler robot with methoxyamine hydrochloride (30 mg/mL in pyridine) and N, O - bis (trimethylsilyl) trifluoroacetamide [BSTFA] + 1% chlorotrimethylsilane [TMCS] (both Thermo Fisher Scientific, Waltham, USA). Samples were left for 1 h before 1 µL was injected onto the GC column using a hot needle technique. Split (1:10) injections were performed for each sample. |
