ABSTRACT
Objective:To study the metabolic mechanism of protective effect of waternut herb extract on primary Aβ SAMP8 damage of mouse hippocampal neurons by metabolic footprinting.Methods:MTT assay was used to determine the proliferation of primary hippocampal neurons in SAMP8 mice with Aβ damage,the effect for the first time on the basis of metabolic footprinting evaluation waternut herb extract.Focus on key metabolic pathways and related metabolic targets,mechanism of primary Aβ SAMP8 damage of mouse hippocampal neurons and pathogenesis of watemut herb extract.Results:MTT assay was used to measure the rate of cell proliferation.The results showed that the cell viability of the primary hippocampal neurons was significantly decreased in the Aβ SAMP8 mice.The study found that metabolic footprinting,compared with littermate wild-type mice,neuronal cell metabolism Aβ SAMP8 damage of mouse anomalies mainly concentrated in the metabolism of folic acid and taufine metabolism associated with nerve cells,by high-throughput mass spectrometric analysis and literature database retrieval to determine the 3 differential metabolites,respectively is L-disodoum alanine (L-Cysteic acid),dihydrofolate (Dihydrofolate),acid (Chorismate),the branch of small molecule metabolites through extract intervention after Amakusa callback trend obviously.Conclusion:the therapeutic effect of watemut herb extract on Aβ SAMP8 damage of mouse primary hippocampal neurons to a certain extent,3 biomarkers of this discovery may be a potential target of Aβ SAMP8 damage of mouse primary hippocampal neurons in the pathogenesis of waternut herb extract,given after these markers were callback trend in different degree,suggesting that watemut herb extract could regulate metabolism related enzymes and metabolic pathways to protect the purpose,to provide the experimental basis for the treatment of Alzheimer's disease watemut herb extract.
