Effect of DGAT2 overexpression on 13C-labeled FA accumulation in adipocytes. The cells were incubated with IFA-DM (DM containing 10 μmol/L 13C16-palmic acid, C16-palmitoleic acid, 13C18-stearic acid, 13C18-oleic acid, C18-linoleic acid, and C20-arachidic acid bound to 60 μmol/L FA-free BSA). After 12 d of differentiation, the mature adipocytes were collected for FA analysis by GC-IRMS. The results are expressed as the percentage of each FA (%). Data are presented as the mean ± SEM of six independent wells.
