Glycogen Synthase Kinase 3 (GSK-3) and Its Inhibitors: Drug Discovery and Development: 2: Castro, Ana, Martinez, Ana, Medina, Miguel, Wang, Binghe:

Inhibition of Glycogen Synthase Kinase (GSK-3) Protects Against Oxidative Stress and Attenuates Apoptosis in Human Lens Epithelial Cells and the Mouse Lens

Findings suggest that GYS2 serves as a prognostic factor and functions as a tumor suppressor in HCC. The newly identified HBx/GYS2/p53 axis is responsible for the deregulation of glycogen metabolism. Glycogen synthesis and the activity of the enzyme glycogen synthase (GS) have been studied in human myoblasts in culture under a variety of experimental conditions. Incubation in the absence of glucose for up to 6 h caused an ∼50% decrease in glycogen content, which was associated with a small decrease in the fractional activity of GS. Acquisition of resistance to gemcitabine is a challenging clinical and biological hallmark property of refractory pancreatic cancer. Here, we investigated whether glycogen synthase kinase (GSK)‐3β, an emerging therapeutic target in various cancer types, is mechanistically involved in acquired resistance to gemcitabine in human pancreatic cancer.

(a) Label the diagram with the appropriate terms to describe glycogen synthase regulation. Note that some texts use glycogen synthase l instead of glycogen synthase a, and glycogen synthase D instead of glycogen synthase b.

Synonym: Stärkesynthase Englisch: Glycogen synthase 1 Definition. Die Glykogensynthase ist das Schlüsselenzym der Glykogensynthese und damit das Enzym, welches der Regulation dieses Stoffwechselweges dient.

PP1 is therefore the only regulator that directly regulates both glycogen synthase and glycogen phosphorylase. Glycogen synthase. A key regulatory enzyme that binds UDP-glucose molecules to the growing glycogen chain; Catalyzes the formation of α-1,4-glycosidic bonds between UDP-glucose and the hydroxyl group of the C4 atom at the free end of the glycogen chain; The rate-determining enzyme of glycogenesis is glycogen synthase.

In enzymology, a [glycogen-synthase-D] phosphatase (EC 3.1.3.42) is an enzyme that catalyzes the chemical reaction [glycogen-synthase D] + H 2 O ⇌ [glycogen-synthase I] + phosphate.

2021-01-28 · Glycogen synthase is one of many enzymes found within the human body. An enzyme is a type of protein which works to catalyze, or speed up, various chemical reactions within the body. Glycogen synthase helps to convert glucose, or blood sugar, into glycogen. Glucose is a simple sugar used by the cells of the body to create energy.

1989). Then glycogen synthase transfers the activated glucose to 4’-OH group of a glucose residue (a nonreducing termini) present in the molecule catalyzing the formation of an α-(1,4) glycosidic bond and therefore extending the chain by one glucose unit.
