Regulation of serotonin 1B receptor by glycogen synthase kinase-3.

In response to 5-hydroxytryptamine (5-HT), the type 1 serotonin receptors (5-HT1Rs) preferentially couple to the inhibitory G protein and elicit many physiological and behavioral processes. However, their regulation by intracellular protein kinases has not been fully investigated. In this study, we identified that glycogen synthase kinase-3 (GSK3) differentially regulates 5-HT1Rs. In receptor-e...

Lifespan regulation of conventional protein kinase C isotypes.

Plasma membrane translocation, following allosteric binding of second messengers, initiates the signal transduction process mediated by cPKC [conventional PKC (protein kinase C)] isotypes. Mechanisms regulating the lifespan of the active enzyme such as its phosphorylation, internalization, dephosphorylation and degradation are key elements of the signalling network. The understanding of such me...

Glycogen synthase kinase-3β may contribute to neuroprotective effects of Sargassum oligocystum against amyloid-beta in neuronal SH-SY5Y cells

Glycogen synthase kinase (GSK)-3β mediates amyloid-beta (Aβ) and oxidative stress-induced neurotoxicity in neurodegenerative disorders. Natural products with antioxidant activity, such as Sargassum (S.) oligocystum may modulate GSK-3β enzyme and protect against Aβ-induced neurotoxicity. Therefore, we aimed to assess the neuroprotective effects of a methanolic extract of S. oligocystum against A...
