Expression of genes related to lipolysis and gluconeogenesis
Principales vias y regulacion de la gluconeogenesis
y glucolisis en el higado.
The glutamate pool in the liver can be processed by glutamate dehydrogenase and originate more ammonia and carbon skeletons, which can be used as metabolic fuel, for gluconeogenesis
or amino acid synthesis (36).
ovatus showed that the hepatic PEPCK activity showed a downward trend within 0-9 h after glucose administration, and then an upward trend 12 h after glucose administration, which suggested that the gluconeogenesis
was inhibited firstly and then gradually increased.
Additionally, given that lactate is one of the substrates for hepatic gluconeogenesis
, an accumulation of lactate may occur when this process is inhibited by metformin .
There was no increase in gluconeogenesis
in glimepiride-treated mice, nor did glucagon levels change.
Ketogenic Diet and Ketogenic Diet Combined with Exercise Attenuate Hepatic Gluconeogenesis
of Diabetic Mice.
The hypoglycemic effect of this "carbohydrate deficit" is only partly offset by the increased endogenous glucose production (EGP) via gluconeogenesis
and the decreased tissue glucose disposal (TGD) [31, 32].
Our liver can also utilize proteins/fats and convert them to glucose via a process called gluconeogenesis
(6,7) To make matters worse, the kidney may further contribute to hyperglycemia in T2DM through increased gluconeogenesis
. (8) An increased understanding of the role of renal glucose handling in the pathophysiology of diabetes mellitus has prompted targeting of the kidney for therapeutic intervention.
In the liver, glucose-6-phosphatase (G6Pase) and phosphoenolpyruvate carboxykinase (PEPCK) participate in committed steps of gluconeogenesis
, playing vital roles in glucose homeostasis, and FOXO1 can regulate their expression levels by directly binding to their target DNA sequence .
GPDH catalyzes the reversible conversion of G3P to dihydroxyacetone phosphate (DHAP), serving as a major link between glycolysis, gluconeogenesis
, and lipid metabolism.
