The fed to fasting transition differentially affects PEPCK protein expression in pericentral and periportal murine hepatocytes

Herrema H , Baller J F W , Kuipers F , Groen A K , Grefhorst A

Hepatic glucose metabolism is zonated. Glycolysis is mainly localized in hepatocytes surrounding the hepatic vein (pericentral zone) whereas gluconeogenesis is mainly carried out by hepatocytes surrounding the portal vein (periportal zone). Expression of the gene encoding the gluconeogenic enzyme phosphoenolpyruvate carboxykinase (PEPCK, PCK1) is reduced upon feeding, an effect mainly controlled by insulin. PEPCK is considered a peri-portal enzyme. However, the differential ef...
