GSK-3β and memory formation
In Alzheimer's disease (AD), tau hyperphosphorylation and neurofibrillary tangle (NFT) formation are strongly associated with dementia, a characteristic and early feature of this disease. Glycogen synthase kinase 3β (GSK-3β) is a pivotal kinase in both the normal and pathological phosphorylation of tau. In the diseased state, hyperphosphorylated tau is deposited in NFTs, the formation of which,...
متن کاملSpirulina maxima Extract Ameliorates Learning and Memory Impairments via Inhibiting GSK-3β Phosphorylation Induced by Intracerebroventricular Injection of Amyloid-β 1–42 in Mice
Spirulina maxima, a microalga containing high levels of protein and many polyphenols, including chlorophyll a and C-phycocyanin, has antioxidant and anti-inflammatory therapeutic effects. However, the mechanisms where by Spirulina maxima ameliorates cognitive disorders induced by amyloid-β 1-42 (Aβ1-42) are not fully understood. In this study, we investigated whether a 70% ethanol extract of Sp...
متن کاملEffect of Epigallocatechin Gallate and Catechin on Overexpression of GSK-3β and IR Genes Induced by Streptozotocin in Rat Brain
Background: Type 2 diabetes mellitus (T2DM) is one of the significant risk factors for Alzheimer disease (AD). Defects in insulin signaling pathway induce AD hallmarks mainly through activation of glycogen synthase kinase-3β (GSK-3β) pathway. Objectives: In this study, we investigated the expression of GSK-3β and insulin receptor (IR) genes in the hippocampi of an animal model of sporadic AD ...
متن کاملMefenamic Acid Attenuates Intracerebroventricular Streptozotocin-Induced Cognitive Deficits in the Rat: A Behavioral Analysis
Intracerebroventricular (ICV) injection of streptozotocin (STZ) in rats is followed by long-term and progressive deficits in learning, memory, and cognitive performance which is somewhat similar to sporadic Alzheimer’s disease (SAD). Epidemiological studies suggest that non-steroidal anti-inflammatory drugs (NSAIDs) could delay or slow the clinical expression of SAD. Therefore, the benefi...
متن کاملThe effect of genistein on intracerebroventricular streptozotocin-induced cognitive deficits in male rat
Abstract Introduction: Intracerebroventricular (ICV) injection of streptozotocin (STZ) causes cognitive impairment in rats. The beneficial effect of genistein (GEN) was investigated on ICV STZ-induced learning, memory, and cognitive impairment in male rats. Methods: For this purpose, rats were injected with ICV STZ bilaterally, on days 1 and 3 (3 mg/kg). The STZ-injected rats received GEN (1...
