Increase of inhibitor-2 of protein phosphatase-2A [Formula: see text] is associated with protein phosphatase-2A (PP2A) inhibition and tau hyperphosphorylation in Alzheimer's disease (AD). Down-regulating [Formula: see text] attenuated amyloidogenesis and improved the cognitive functions in transgenic mice expressing amyloid precursor protein (tg2576). Here, we found that silencing [Formula: see...
We found that resveratrol enhances interferon (IFN)-γ-induced tryptophanyl-tRNA-synthetase (TTS) expression in bone marrow- derived dendritic cells (BMDCs). Resveratrol-induced TTS expression is associated with glycogen synthase kinase-3β (GSK-3β) activity. In addition, we found that resveratrol regulates naïve CD8+ T-cell polarization by modulating GSK-3β activity in IFN-γ-stimulated BMDCs, an...
Glycogen synthase kinase-3β (GSK-3β) in cancer cells is a critical regulatory component of both cellular metabolism and epithelial-mesenchymal transition (EMT) processes via regulation of the β-catenin/E-cadherin and phosphoinositide 3-kinase (PI3K)/AKT signaling pathway. Lipogenesis of cancer cells also plays a critical role in survival and metastasis. We investigated the role of GSK-3β-mediat...
Skeletal muscle atrophy commonly occurs in acute and chronic disease. The expression of the muscle-specific E3 ligases atrogin-1 (MAFbx) and muscle RING finger 1 (MuRF1) is induced by atrophy stimuli such as glucocorticoids or absence of IGF-I/insulin and subsequent Akt signaling. We investigated whether glycogen synthase kinase-3β (GSK-3β), a downstream molecule in IGF-I/Akt signaling, is requ...
Transient brain ischemia has been shown to induce hyperphosphorylation of the microtubule-associated protein tau. To further determine the mechanisms underlying these processes, we investigated the interaction between tau, glycogen synthase kinase (GSK)-3β and protein phos-phatase 2A. The results confirmed that tau protein was dephosphorylated during brain ischemia; in addition, the activity of...
Ginkgolide K (GK) belongs to the ginkgolide family of natural compounds found in Ginkgo biloba leaves, which have been used for centuries to treat cerebrovascular and cardiovascular diseases. We evaluated the protective effects of GK against neuronal apoptosis by assessing its ability to sustain mitochondrial integrity and function. Co-immunoprecipitation showed that Drp1 binding to GSK-3β was ...
گلیکوژن سنتازکیناز3 بتا، کلید تنظیمی است که خروجی بسیاری از مسیرهای پیامرسانی را تعیین میکند. مهار آن در افزایش بقای نورونی مؤثر گزارش شده است. ازاینرو پژوهش حاضر به بررسی اثر شش هفته تمرین استقامتی بر بیان ژن GSK-3β در بخش حرکتی نخاع رتهای نر ویستار با نوروپاتی دیابت میپردازد. بدین منظور 16 سر رت نر ویستار بهطور تصادفی به چهار گروه سالم کنترل، سالم تمرین، نوروپاتی کنترل و نوروپاتی تمرین...
The phosphorylation of Amyloid Precursor Protein (APP) at Thr668 plays a key role in APP metabolism that is highly relevant to AD. The c-Jun-N-terminal kinase (JNK), glycogen synthase kinase-3β (GSK-3β) and cyclin-dependent kinase 5 (Cdk5) can all be responsible for this phosphorylation. These kinases are activated by excitotoxic stimuli fundamental hallmarks of AD. The exposure of cortical neu...
Patients with chronic kidney disease (CKD) are at increased risk for bone fractures compared with the general population. Repression of the Wnt/β-catenin signaling pathway is associated with bone abnormalities. Inhibition of glycogen synthase kinase (GSK)-3β, a critical component of the Wnt/β-catenin signaling pathway, increases bone volume through accumulation of β-catenin. It remains unknown ...
Glycogen synthase kinase (GSK)-3β and related enzymes are associated with various forms of neuroinflammation, including spinal cord injury (SCI). Our aim was to evaluate whether lithium, a non-selective inhibitor of GSK-3β, ameliorated SCI progression, and also to analyze whether lithium affected the expression levels of two representative GSK-3β-associated molecules, nuclear factor erythroid 2...
