Abstract:
Intestinal gluconeogenesis (IGN) is a regulatory function of energy homeostasis. IGN-produced glucose is sensed by the gastrointestinal nervous system and sends a signal to regions of the brain regulating food intake and glucose control. IGN is activated by dietary protein and dietary fibre, and by gastric bypass surgery of obesity. Glutamine, propionate and succinate are the main substrates used for glucose production by IGN. Activation of IGN accounts for the well-known satiety effect of protein-enriched diets and the anti-obesity and anti-diabetes effects associated with fibre feeding and gastric bypass surgery. Genetic activation of IGN in mice shows the same beneficial effects, independently of any nutritional manipulation, including a marked prevention of hepatic steatosis under hypercaloric feeding. The activation of IGN could thus be the basis for new approaches to prevent or correct metabolic diseases in humans.
