Very low glucose levels in FABP4/5 DKO mice in the fasted state regardless of cold exposure.

<p>(A to H) Blood was collected from the retro-orbital plexus before and after cold exposure to measure the serum levels of glucose (A and B), TGs (C and D), NEFAs (E and F), and ketone bodies (G and H) in the fed (A, C, E, and G) and the fasted states (B, D, F, and H). n = 5–6/group. *p<0.05; **p<0.01; ***p<0.001. Note that the blood was collected 4 h after cold exposure for the fed groups and 2 h after cold exposure for the fasted groups because many DKO mice died during prolonged cold exposure in the fasted state.
