Caption: Mice on the left: During fasting, the CREB/TORC2 switch turns on glucose production in the liver. Salk researchers made this process visible with the help of luciferase, which normally produces the glow of firefly tail but in this case lights up the livers of mice actively producing glucose. Mice on the right: In response to feeding, mice produce insulin, which shuts down glucose production in the liver.
