| Study Title | Omega-6 and omega-3 oxylipins are implicated in soybean oil-induced obesity in mice (part III) |
| Study Summary | In this study we have compared the metabolic effects of conventional soybean oil to those of genetically modified Plenish soybean oil, that is low in linoleic acid and high in oleic acid. This work builds on our previous study showing that soybean oil, rich in polyunsaturated fats, is more obesogenic and diabetogenic than coconut oil, rich in saturated fats (PMID: 26200659). Here, in order to elucidate the mechanisms responsible for soybean oil induced obesity, we have performed the first ever metabolomics (in plasma and liver) and proteomics on the livers of mice fed the two soybean oil diets (plus those fed a high coconut oil and Viv chow diet). Our results show that the new high oleic soybean oil induces less obesity and adiposity than conventional soybean oil, but can cause hepatomegaly and liver dysfunction. Metabolomic analysis reveals that the hepatic and plasma metabolic profiles differ considerably between the two soybean oils. Hepatic C18 oxylipin metabolites of omega-6 (ω6) and omega-3 (ω3) fatty acids (linoleic and α-linolenic acid, respectively) in the cytochrome P450/soluble epoxide hydrolase pathway were found to correlate positively with obesity. |

Keep all samples on ice during extraction period h. Dry down one (1) 500μL aliquot to complete dryness i. Perform cleanup on dried aliquot using 500μL of 50/50 v/v ACN/H2O j. Transfer supernatant and dry to completeness k. Submit for Derivatization 9) Analysis of Complex Lipids (LCQTOF) a. Add 225μL of ice-cold “degassed” MeOH containing “ISTD mixture” to homogenized 5mg aliquot b. Vortex for 10 seconds c. Add 750μL of ice-cold “degassed” MTBE containing 22:1 CE ISTD d. Vortex for 10 seconds e. Shake on Orbital Mixer for 6min at 4C f. Add 188μL of room temperature H2O g. Vortex for 20 seconds h. Centrifuge for 2min at 14,000 rcf i. Transfer two (2) aliquots of 350μL of top layer, one for backup stored in -20C, the other for analysis j. Keep bottom layer and store in -20C k. Dry down one (1) 350μL aliquot to dryness using the Speedvac l. Resuspend samples in 108.6μL of 50ng/mL CUDA m. Vortex and sonicate for 5minutes n. Centrifuge for 2min at 14,000 rcf o. Transfer 90μL to an amber vial with micro-insert (non-diluted) p. Transfer 10μL to a new 1.5mL eppendorf tube, dilute 20X with 50ng/mL CUDA in 90:10 MeOH:Toluene (10μL + 190μL CUDA) and transfer 100μL to amber vial with micro-insert (diluted for TGs) i. The dilution is based off previous experiences with liver samples |
