Serum levels of alanine transaminase (A), glucose (B), insulin (D), free fatty acids (E), glycerol (F), leptin (G), TG (H), free cholesterol (I) and cholesterol ester (J) were measured in overnight-fasted piceatannol-treated diet-induced obese mice. (C) An IPGTT was performed in mice with 2 g/kg glucose i.p. injection at the end of the study. Data are presented as means ± SEM. (n=7–8, *, p < 0.05; **, p < 0.01).
