Effects of Adiponectin on Glucose Metabolism in the Hepatopancreas of Grass Carp (Ctenopharyngodon idella)

Figure 7

Schematic diagram showing the roles of adiponectin in the regulation of glucose metabolism in the hepatopancreas of grass carp under fasting conditions. Adiponectin A and adiponectin B reduced basal serum glucose levels of grass carp, but they have opposite regulatory effects on glut2 mRNA expression. Adiponectin A upregulated the expression of enzyme genes related to glycolysis (gk and pk) and glycogen synthesis (gys) in the hepatopancreas, while adiponectin B promoted expression of pk, g6pase, and gys. Finally, adiponectin A and adiponectin B caused an increase in hepatopancreas glycogen content.
