This last point is of utmost importance for the GSK-3 inhibition as a therapeutic approach Se hela listan på academic.oup.com Glycogen Synthase Kinase 3 (GSK3) is one of the Serine/Threonine protein kinases, which has gained a lot of attention for its role in a variety of pathways. It has two isoforms, GSK3α and GSK3β. However, GSK3β is highly expressed in different areas of the brain and has been implicated in Alzheimer’s disease as it is involved in tau phosphorylation. Glycogen synthase kinase 3: an introductory synopsis -- Glycogen synthase kinase-3[beta] (GSK-3[beta]) a key signaling enzyme: a developmental neurobiological perspective -- Role of GSK-3/Shaggy in neuronal cell biology -- The crystal structures of glycogen synthase kinase 3 -- Kinase-kinase and site-site interactions in the phosphorylation of tau by GSK-3 -- GSK-3, a key player in Alzheimer's Glycogen synthase kinase (GSK)-3 has been implicated in the regulation of multiple cellular physiological processes in skeletal muscle. Selective cell-permeable reversible inhibitors (INHs) of GSK-3 (CT98014 and CHIR98023 [Chiron, Emeryville, CA] and LiCl) were used to evaluate the role of GSK-3 in controlling glucose metabolism. Glycogen synthase kinase-3 (GSK-3) α and β are highly conserved serine–threonine kinases initially described as key enzymes in regulating glycogen metabolism, with critical roles in Wnt/β-catenin signaling, immune regulation, and maintenance of stem cell identity .

Glycogen synthase kinase 3 (GSK‐3) was first discovered in 1980 as one of the key enzymes of glycogen metabolism. Since then, GSK‐3 has been revealed as one of the master regulators of a diverse range of signaling pathways, including those activated by Wnts, participating in the regulation of numerous cellular functions, suggesting that its activity is tightly regulated.

One of its isoforms, GSK-3β, acts as both a tumor suppressor and a proto-oncogene, depending on the downstream target (2). GSK3-β is considered a key player in AD pathophysiology since dysregulation of this kinase influences all the major hallmarks of the disease including: tau phosphorylation, amyloid-β production, memory, neurogenesis and synaptic function. Three closely related forms of glycogen synthase kinase 3 (GSK-3alpha, GSK-3beta and GSK-3beta2) have a major role in Wnt and Hedgehog signaling pathways and regulate the cell-division cycle, stem-cell renewal and differentiation, apoptosis, circadian rhythm, transcription and insulin action.

Glycogen synthase kinase-3β (GSK-3β) is a ubiquitously expressed constitutively active serine/threonine kinase that phosphorylates cellular substrates and thereby regulates a wide variety of cellular functions, including development, metabolism, gene transcription, protein translation, cytoskeletal organization, cell cycle regulation, and apoptosis. Not long ago, glycogen synthase kinase-3 (GSK3) seemed to be a rather curious enzyme in a number of ways, but perhaps not one of especially widespread importance (Grimes and Jope, 2001, Woodgett, 2001). GSK3 was considered of some interest because it has the unconventional characteristics for a kinase of being constitutively active, its substrates usually need to be pre-phosphorylated by another kinase, and it is inhibited, rather than activated, in response to stimulation of the two main Glycogen synthase kinase-3 (GSK-3), a serine/threonine kinase, is a regulator of multiple signaling pathways (1). One of its isoforms, GSK-3β, acts as both a tumor suppressor and a proto-oncogene, depending on the downstream target (2). GSK3-β is considered a key player in AD pathophysiology since dysregulation of this kinase influences all the major hallmarks of the disease including: tau phosphorylation, amyloid-β production, memory, neurogenesis and synaptic function.

A large body of evidence supports speculation that pharmacological inhibitors of GSK-3 could be used to treat several diseases, including Alzheimer's disease and other neurodegenerative diseases Tideglusib is a non-ATP competitive inhibitor of glycogen synthase kinase 3beta (GSK3beta) and has neuroprotective effects.

2021-02-20 · Abstract Glycogen synthase kinase (GSK) 3 acts to negatively regulate multiple signaling pathways, including canonical Wnt signaling. The two mammalian GSK3 proteins (alpha and beta) are at least partially redundant. While Gsk3a KO mice are viable and display a metabolic phenotype, abnormal neuronal development, and accelerated aging, Gsk3b KO animals die late in embryogenesis or at birth Glycogen synthase kinase 3 (GSK-3), EC 2.7.11.26, is a serine-threonine kinase with two isoforms (α and β), that was originally discovered as an important enzyme in glycogen metabolism. GSK-3 was subsequently shown to function in cellular division, proliferation, motility and survival. Obesity induces lipotoxic cardiomyopathy, a condition in which lipid accumulation in cardiomyocytes causes cardiac dysfunction. Here, we show that glycogen synthase kinase-3α (GSK-3α) mediates lipid accumulation in the heart.
