OBJECTIVE: To investigate the effect of osthole on the expression of amyloid precursor protein (APP) in Alzheimer's disease (AD) cell model and its mechanism. METHODS: The SH-SY5Y cell with over expression of APP was established by transfection by liposome 2000. The cells were treated with different concentrations of osthole, and the cell viability was determined by MTT and lactate dehydrogenase (LDH) assay. The differentially expressed miRNAs with and without osthole treatment were detected by miRNA array, and the target genes binding to the differentially expressed miRNAs were identified and verified by databases and Cytoscape. After the inhibitor of the differentially expressed miRNA was transduced into cells, the changes of APP and amyloid ß (Aß) protein were determined by immunofluorescence cytochemistry, and the mRNA expression of APP was determined by RT-PCR. RESULTS: The AD cell model with over expression of APP was established successfully. The results of MTT and LDH assay showed that osthole had a protective effect on cells and alleviated cell damage. miR-101a-3p was identified as the differentially expressed miRNA, which was binding to the 3'-UTR of APP. Compared with APP group, the expression of APP and Aß protein and APP mRNA increased in the miR-101a-3p inhibitor group (all P<0.01), while the expression of APP and Aß protein and APP mRNA decreased in the cells with osthole treatment (all P<0.01). CONCLUSIONS: Osthole inhibits the expression of APP by up-regulating miR-101a-3p in AD cell model.
