Summary of "Glycogen structure in type 1 diabetic mice: Towards understanding the origin of diabetic glycogen molecular fragility."

Glycogen is a complex branched glucose polymer. Liver glycogen in db/db mouse, a type-2 diabetic mouse model, has been found to be more molecularly fragile than in healthy mice. Size-exclusion chromatography was employed in this study to investigate the molecular structure of liver glycogen in two types of type 1 diabetic mouse models (NOD and C57BL/6J mice), sacrificed at various times throughout the diurnal cycle, and the fragility of liver glycogen after exposure to a hydrogen-bond disruptor were tested. Type 1 diabetic mice exhibit a similar glycogen fragility with that observed for db/db mice. This eliminates many of the potential causes for glycogen molecular fragility; the most likely explanation is that it is caused by high blood-glucose level and/or insulin deficiency, both phenotypes being common to both type 1 and type 2 diabetic mice. This result suggests ways towards new drug targets for the management of diabetes.

Targeted disruption of glycogen synthase kinase-3β in cardiomyocytes attenuates cardiac parasympathetic dysfunction in type 1 diabetic Akita mice.

Bladder dysfunction in diabetes progresses gradually over time. However, the mechanisms of the development are not clear. We test the hypothesis that oxidative stress plays a key role in the developme...

Methodological considerations for studies of brain glycogen.

Glycogen stores in the brain have been recognized for decades, but the underlying physiological function of this energy reserve remains elusive. This uncertainty stems in part from several technical c...

Medical and Biotech [MESH] Definitions

An autosomal recessive metabolic disorder due to deficient expression of amylo-1,6-glucosidase (one part of the glycogen debranching enzyme system). The clinical course of the disease is similar to that of glycogen storage disease type I, but milder. Massive hepatomegaly, which is present in young children, diminishes and occasionally disappears with age. Levels of glycogen with short outer branches are elevated in muscle, liver, and erythrocytes. Six subgroups have been identified, with subgroups Type IIIa and Type IIIb being the most prevalent.

An isoenzyme of GLYCOGEN PHOSPHORYLASE that catalyzes the degradation of GLYCOGEN in liver tissue. Mutation of the gene coding this enzyme on chromosome 14 is the cause of GLYCOGEN STORAGE DISEASE TYPE VI.

An isoenzyme of GLYCOGEN PHOSPHORYLASE that catalyzes the degradation of GLYCOGEN in muscle. Mutation of the gene coding this enzyme is the cause of McArdle disease (GLYCOGEN STORAGE DISEASE TYPE V).

An autosomal recessive glycogen storage disease in which there is deficient expression of 6-phosphofructose 1-kinase in muscle (PHOSPHOFRUCTOKINASE-1, MUSCLE TYPE) resulting in abnormal deposition of glycogen in muscle tissue. These patients have severe congenital muscular dystrophy and are exercise intolerant.

A strain of non-obese diabetic mice developed in Japan that has been widely studied as a model for T-cell-dependent autoimmune insulin-dependent diabetes mellitus in which insulitis is a major histopathologic feature, and in which genetic susceptibility is strongly MHC-linked.
