Abstract:Objective:To study the inhibition of β-amyloid precursor protein(β-APP) gene expression by Haifengteng.Method:Northern Blot analysis was used to investigate the level of β-APP mRNA,and cell viability,LDH release and colony formation assay were used to study the effect of Hairengteng of neurons.Result:Haifengteng inhibited the expression of β-APP gene selectively without causing cell injuries.Conclusion:β-APP is closely related to Alzheimer‘s disease.The findings in this study could be a basis for Haifengteng to have thrapeutic potentials in treating Alzheimer‘s disease.
