Abstract:
Objective:The non targeted high-throughput urine metabolomics technology was used to study the pathogenesis of APP/PS 1 double transgenic mice and the mechanism of action of Gouteng san.Methods:5-month-old APP/PS 1 double transgenic mice were test with Morris water maze for spatial learning ability.Then we employed the non targeted high-throughput urine metabolomics technology to study the pathogenesis of APP/PS1 double transgenic mice based on the metabolic network.The focus investigation of the key pathways and the observation of the treatment by Morris water maze and metabolic level have been used after spatial learning ability damaged confirmed.Results:The comparison between APP/PS1 double transgenic mice and normal mice suggested that a significant longer was existed in former,which was call-back by Gouteng san.With the non targeted high-throughput urine metabolomics analysis and pathway focused analysis,we found certain signals from metabolic profiling,which was identified to be 6 biomarkers associated with learning and memory function by mass spectrometry analysis or authoritative database.Respectively,they were taurine,pteroylglutamic acid,neopterin,glutaurine,2-oxoglutarate and dihydroneopterin.They were mainly related to taurine metabolism and folate metabolism and represented an effective callback.Conclusion:Gouteng san possess a favorable effect on learning and memory ability of APP/PS1 double transgenic mice,6 biomarkers may be a potential target for the pathogenesis of APP/PSI double transgenic mice and provide experimental basis for the study of Gouteng san.
