摘要
Alzheimer's disease (AD) is a complex neurodegenerative disorder and is the most common form of dementia in the elderly. Accumulating evidence in AD research suggests that alterations in the microRNA (miRNA) network could contribute to risk for the disease. miRNAs are conserved small non-coding RNAs that control gene expression at the posttranscriptional level and are essential for neuronal function and survival. The results from recent profiling experiments in humans suggest that a number of specific miRNAs are misregulated in disease conditions, several of which have been implicated in the regulation of key genes involved in AD, including APP, BACE1 and MAPT. Moreover, rare disease-specific polymorphisms have been identified in known and putative miRNA target sites located within the 3'untranslated regions (3'UTRs) of APP and BACE1 genes. Here, we review current findings regarding miRNA research in humans and various cellular and animal models to provide a strong basis for future research aimed at understanding the potential contribution of miRNAs to AD pathophysiology.
