Study ID	ST001687
Study Title	Non-transformed cells respond to fat by inducing glucose metabolism
Study Summary	C57BL/6N mice were obtained from the KU Leuven animal laboratory. 2-week old mice were injected i.p. diethylnitrosamine (DEN, 25 mg/Kg) in phosphate buffered saline (3.17 mg/ml).s At 6-weeks of age, mice were randomized into two groups: control diet (CD, E15742-33 ssniff Spezialdiäten GmbH) or high fat diet (HFD, S8655-E220 sniff Spezialdiäten GmbH). At endpoint, mice were sacrificed by injecting approximately 50 µl of a 60 mg/ml Nembutal solution (Vetoquinol). Tissues were immediately excised, washed in ice-cold saline, placed into pre-labelled bags and frozen using a liquid nitrogen-cooled biosqueezer. The bags were then placed in liquid nitrogen until all collections were finished and finally stored at -80°C until further processing. Where necessary tumors were rapidly separated from normal tissue prior to freezing with tumor and normal tissue being stored separately.

Sample Preparation:

Sampleprep ID:	SP001770
Sampleprep Summary:	Lipids were extracted from liver samples with 700 μl of sample (100 μl of plasma diluted in PBS, or 700 μl of homogenized cells) was mixed with 800 μl 1 N HCl:CH3OH 1:8 (v/v), 900 μl CHCl3, 200 μg/ml of the antioxidant 2,6-di-tert-butyl-4-methylphenol (BHT; Sigma Aldrich) and 3 μl of SPLASH® LIPIDOMIX® Mass Spec Standard (#330707, Avanti Polar Lipids). After vortexing and centrifugation, the lower organic fraction was collected and evaporated using a Savant Speedvac spd111v (Thermo Fisher Scientific) at room temperature and the remaining lipid pellet was stored at - 20°C under argon. Just before mass spectrometry analysis, lipid pellets were reconstituted in 100% ethanol.
