Flavonoids are present in foods such as fruits and vegetables. A relationship between the consumption of flavonoid-rich foods and prevention of human disease including neurodegenerative disorders has been demonstrated. We assessed the effect of rutin (3,3,4',5,7-pentahydroxyflavone-3-rhamnoglucoside) on the mitogen-activated protein kinase (MAPK) pathway, memory retrieval and oxidative stress in rats injected with beta-amyloid(A beta), which is implicated to have an important role in Alzheimer's disease (AD). A beta was injected bilaterally in the deep frontal cortex of rat brain. Next, rutin and saline were injected (i.p.) for 3 weeks. In comparison to the control group, rutin significantly increased extracellular signal-regulated protein kinase 1 (ERK1), cAMP response element-binding protein (CREB) and brain-derived neurotrophic factor (BDNF) gene expression in the hippocampus of rats. Rutin (100 mg/kg) significantly increased memory retrieval compared to the control group. Malondialdehyde (MDA) level in the hippocampus of the rutin group was significantly lower than those in the control group. The content of sulfhydryl groups in the rutin group was higher than that in the control group. The findings show a possibility that rutin may have beneficial effects against neurotoxicity of A beta on memory in rats. (C) 2013 Elsevier Ireland Ltd. All rights reserved.
