...Francisco Llavero; José L. Zugaza The three isoforms of glycogen phosphorylase — PYGM, PYGB, and PYGL — are expressed in glial cells. Unlike PYGB and PYGL, PYGM is the only isoform regulated by Rac1. This specific regulation may confer a differential functional role compared with the other glycogen...

...Stephen Bornemann It has long been reported that Mycobacterium tuberculosis is capable of synthesizing the α-glucan glycogen. However, what makes this bacterium stand out is that it coats itself in a capsule that mainly consists of a glycogen-like α-glucan. This polymer helps the pathogen evade...

...Margit S. Müller Astrocytic glycogen degradation is an important factor in metabolic support of brain function, particularly during increased neuronal firing. In this context, glycogen is commonly thought of as a source for the provision of energy substrates, such as lactate, to neurons. However...

... insulin receptor tyrosine kinase signalling. Glycogen synthesis and glycogenolysis are phosphorylation dependent, and amenable to kinase inhibition, as are some nuclear hormone receptors, and these will be briefly discussed. 1 email [email protected] 6 10 2004 © 2005...

...S. Patel; B. Doble; J.R. Woodgett Glycogen synthase kinase-3 is an unusual protein serine/threonine kinase that, unlike most of its 500-odd relatives in the genome, is active under resting conditions and is inactivated upon cell stimulation. The two mammalian isoforms, GSK-3α and β, play largely...

...L. Andersson The RN − (rendement Napole, French for Napole yield) phenotype is common in Hampshire pigs and is characterized by a 70% increase in glycogen content in skeletal muscle and large effects on meat characteristics (pH, water content, technological yield and lean meat content...

... for the effects of 5-aminoimidazole-4-carboxamide riboside (‘AICAR’) and hypoxia, and is possibly required for a portion of exercise-induced glucose uptake. These same mice could not maintain sufficient glycogen in their skeletal muscle and it was rapidly depleted when the animals were subjected to mild exercise...
