Study TitleEffect of high-fat diet on serum lipidome in mice
Study SummaryWe analyzed mouse serum samples from a mouse dietary intervention experiment. Briefly, C57BL/6 mice (n=44) were divided into 4 groups (n=11 per group) and fed High-fat diet (HFD), 1% deoxycholic acid (DCA) in drinking water, both, or left as control for 9 months. For quality control, 12 TQC samples and 2 blanks were also included in the analysis (total 58 samples and 6 groups). The two treatments were selected to demonstrate the ability of lipidomics to detect gross changes induced by HFD in the serum lipidome, as well as specific/minor changes induced by the secondary bile acid (DCA) through regulation of liver lipid metabolism.

Collection ID:CO001392
Collection Summary:Mouse serum lipids were extracted using the lipid extraction method by Matyash et al(J Lipid Res 2008, 49, (5), 1137-46). Mouse serum (30 µL) was added to 215 µL of ice-cold methanol containing 50 µg/mL butylated hydroxytoluene (BHT). Samples were homogenized by three rounds of vortex mixing for 30 seconds, freezing in liquid nitrogen for one minute, thawing for two minutes and sonicating for 10 minutes at 15°C, power 100% in a Grant XUB18 bath sonicator.
Sample Type:Blood (serum)
Storage Conditions:-80℃
