There were no significant differences between the diabetic and control rat liver microsomes in the activities of UDP N-acetylglucosamine pyrophosphatase, UDP galactose pyrophosphatase, or CMP sialic acid phosphatase.

These results are discussed in relation to our previously reported alterations in glycosyltransferase activities, and plasma membrane glycoprotein composition in the livers of rats made insulin-resistant by a carbohydrate-free, high-fat diet and to the observation of Carter and his colleagues (FEBS Lett. 1979; 104:389-92.) that streptozotocin diabetes alters the glycoprotein composition of rat liver plasma membranes.

beta-1,4-N-Acetylgalactosaminyltransferase (EC 2.4.1.92; GalNAc-T) is a glycosyltransferase involved in the synthesis of gangliosides GM2 and GD2 as well as glycolipid GA2.

The pseudooligosaccharide acarbose is a potent inhibitor of amylases, glucosidases, and cyclodextrin glycosyltransferase and is clinically used for the treatment of so-called type II or insulin-independent diabetes.

To determine the role of ganglioside synthesis within the CNS, mice carrying null mutations in two critical ganglioside-specific glycosyltransferase genes, Siat9 (encoding GM3 synthase) and Galgt1 (encoding GM2 synthase), were generated.

Pancreatic beta cell-surface expression of glucose transporter 2 (Glut-2) is essential for glucose-stimulated insulin secretion, thereby controlling blood glucose homeostasis in response to dietary intake.

We show that the murine GlcNAcT-IVa glycosyltransferase is required for Glut-2 residency on the beta cell surface by constructing a cell-type- and glycoprotein-specific N-glycan ligand for pancreatic lectin receptors.

Elevated concentrations of free fatty acids caused nuclear exclusion and reduced expression of the transcription factors FOXA2 and HNF1A in beta cells.

|
This resulted in a deficit of GnT-4a glycosyltransferase expression in beta cells that produced signs of metabolic disease, including hyperglycemia, impaired glucose tolerance, hyperinsulinemia, hepatic steatosis and diminished insulin action in muscle and adipose tissues.

The glucose transporter isoform, GLUT2, -mediated glucose sensing is essential for maintaining normal glucose-stimulated insulin secretion in pancreatic beta cells.
|

|
We previously reported that GnT-IVa glycosyltransferase is required for the production of an N-glycan structure that acts as a ligand for galectins to form the glycan-galectin lattice that maintains the stable cell surface expression of GLUT2, and cellular glucose transport activity, although the functional relevance of the N-glycosylation of GLUT2 to its membrane sub-domain distribution is not fully understood.
|

|
In the present study, we demonstrated that disruption of the GLUT2 N-glycan-galectin lattice by the genetic inactivation of GnT-IVa, or by treatment of pancreatic beta cells with competitive glycan mimetics, induced the re-distribution of GLUT2 into the lipid-raft microdomain.

|
This subsequently resulted in the binding of Stomatin to GLUT2 and an attenuation of cellular glucose transport activity.
|

|
Moreover, disruption of the lipid-raft microdomain by treatment with methyl-β-cyclodextrin caused the GLUT2 to be released from lipid-rafts and reactivation of the cellular glucose transport activity in GnT-IVa deficient beta cells.
|

|
These results indicate that the membrane sub-domain distribution of GLUT2 is associated with the glucose transport activity of beta cells, in which the GnT-IVa-dependent formation of the N-glycan-galectin lattice plays an important role.
