Figure 2: Plasma Angptl4 levels in response to changes in plasma FFA concentrations on t0 and t360 in 9 subjects. A) Lowering plasma FFA levels decreased Angptl4 plasma concentrations after glycerol infusion for 6 h. B) Rise in plasma FFA levels increased Angptl4 plasma concentrations after lipid infusion for 6h. All measurements were in duplicate and averaged.
