APP intracellular domain supperess neuronal differentiation through transcriptional regulation of
mir663
A
myloid precursor protein (APP) is best known for its involvement in the pathogenesis of Alzheimer’s disease. We have
previously demonstrated that APP intracellular domain (AICD) regulates neurogenesis; however, the mechanisms
underlyingAICD-mediated regulation of neuronal differentiation are not yet fully characterized. Using genome-wide chromatin
immunoprecipitation approaches, we found that AICD is specifically recruited to the regulatory regions of several microRNA
genes, and acts as a transcriptional regulator for miR-663, miR-3648 and miR-3687 in human neural stem cells. Functional
assays show that AICD negatively modulates neuronal differentiation through miR-663, a primate-specific microRNA.
Microarray data further demonstrate that miR-663 suppresses the expression of multiple genes implicated in neurogenesis,
including FBXL18 and CDK6. Our results indicate that AICD has a novel role in suppression of neuronal differentiation via
transcriptional regulation of miR-663 in human neural stem cells.
