Study IDST001508
Study TitleLiver metabolomics in old liver-specific SIRT6 overexpressing mice
Study SummaryOur previous data had suggested that gluconeogenesis capacity from the precursors lactate and glycerol declines in old C57BL/6 mice. This decline was rescued by whole body SIRT6 overexpression, but not in liver-specific SIRT6 overexpression. Here we preformed liver metabolomics in old liver-specific SIRT6 overexpression and control mice.

Project Title:Hepatic [U-13C]Lactate tracing and metabolomics in young and old WT and SIRT6 overexpressing mice
Project Type:MS analysis
Project Summary:Our previous data had suggested that gluconeogenesis capacity from the precursors lactate and glycerol declines in old C57BL/6 mice. This decline was rescued by whole body SIRT6 overexpression. Since the liver is the main gluconeogenic organ, we performed here liver metabolomics in young (6 months) versus old (20-24 months) WT and SIRT6-transgenic mice. We used liver tissues of 6h morning-fasted mice, either in naïve state or 15 minutes after intraperitoneal injection of [U-13C]Lactate.

Collection:

Collection ID:CO001577
Collection Summary:Mice were euthanized by cervical dislocation, left liver lobe was collected as fast as possible (<30 sec) and immediately flash-frozen in liquid nitrogen. Tissues were stored at -80C until metabolite extraction.
Sample Type:Liver
Storage Conditions:-80℃

Treatment:

Treatment ID:TR001597
Treatment Summary:All mice were fasted for 6h (8AM-2PM). Tail blood was collected from all mice for less than 2 minutes, followed by mouse sacrifice.
Animal Fasting:6h morning fast
Animal Endp Euthanasia:Cervical dislocation

Sample Preparation:

Sampleprep ID:SP001590
Sampleprep Summary:Frozen liver pieces weighting ~30mg were transferred into soft tissue homogenizing CK 14 tubes containing 1.4 mm ceramic beads (Bertin corp.) prefilled with 1 ml of cold (-20°C) metabolites extraction solvent (Methanol: Acetonitrile:H2O, 50:30:20) and kept on ice. Samples were homogenized using precellys 24 tissue homogenizer (3X20sec at 6000 rpm, with a 30sec gap between each of the three cycles, Bertin Technologies) cooled to 2°C. Homogenized extracts were centrifuged in the Precellys tubes at 18,000g for 15 minutes at 4°C, supernatants were collected in microcentrifuge tubes and centrifuged again at 18,000g for 10 minutes at 4°C. The supernatants were transferred to glass HPLC vials and kept at -75 °C prior to LC-MS analysis.
