＜正＞A C-glycoside compound, puerarin （4’,7-dihydroxy-8-β-D-glucosylisoflavone） is present in a large amount of the active components of Puerariae radix, a commonly used Chinese herb, which exerts sedative and antipyretic actions and is often used to treat influenza, wrist stiffness and headache. A number of investigations were carried out internationally to identify the physiological activities of puerarin such as antiproliferative effect on human cancer cell lines, preventing cancer, inhibiting alcohol dehydrogenase, improving blood circulation. In order to im-

oc-Synuclein is a presynaptic protein which is implicated in some neurodegenerative disorders including Parkinson’s disease,dementia with Lewy bodies,multiple systems atrophy,and Hallervorden-Spatz disease,and its overexpression contributes to the loss of dopaminergic *** the role ofα-synuclein in these paradigms has been widely documented,its exact function is still *** the dysfunction of the transcription factor nuclear factor (NF-κB) also exists in many neurodegenerative *** this reason the purpose of this study was to investigate the molecular mechanism ofα-synuclein’s toxicity and its association with NF-κB by MTT assay,Western blot method,and luciferase *** showed that overexpressedα-synuclein and 1-methyl-4-phenylpyridinium(MPP suppressed the SH-SY5Y cell viability and attenuate NF-κB-mediated luciferase expression ***,the impairment function was enhanced with the increase ofα-synuclein protein *** also found that overexpressedα-synuclein localized both in the cytoplasms and nuclei,down-regulated the anti-apoptotic Bcl-2.expression and up-regulated the proapoptotic glycogen synthase kinase 3β(GSK3β) protein *** conclusion,all these findings mentioned above suggested thatα-synuclein shared some toxic functional homology with neurotoxin MPP,and the proapoptotic effects of alpha-synuclein might be mediated at least in part by the impairment of NF-κB signaling pathway which involves GSK3β.
