FIG. 2.
POA injection of insulin increased fatty acid utilization and BAT activity A: The 6-h profile of RER of mice treated with vehicle of 0.03 IU insulin in the POA, demonstrating that insulin injection decreased RER, indicating an elevation of fatty acid utilization. B: The 3-h profile of PET/CT of 18F-FDG uptake in rats injected with vehicle or 0.03 IU insulin in the POA. Top panel shows the representative PET/CT; squared in dotted lines is the area investigated after treatment with insulin or vehicle shown below. The anatomical position of BAT is indicated with an arrow. C: The 3-h profile quantification of 18F-FDG uptake into BAT after insulin treatment as indicated. Data are presented as means ± SE. *P < 0.05.
