چکیده

Although large numbers of microRNAs (miRNAs) expressed in Alzheimer disease (AD) have been detected, their functions and mechanisms of regulation remain to be fully clarified. Beta-site Amyloid precursor protein Cleaving Enzyme 1 (BACE1) has been one of the prime therapeutic targets for AD. Here, we identified that miR-124 levels are gradually decreased in AD. In addition, we demonstrated that miR-124 suppresses BACE1 expression by directly targeting the 3'UTR of Bace1 mRNA in vitro. Inhibition of miR-124 significantly increased BACE1 levels in neuronal cells. In contrast, miR-124 overexpression significantly suppressed BACE1 expression in cells. And finally we determined that downregulation of miR-124 alleviated Aβ-induced viability inhibition and decreased apoptosis in SH-SY5Y cells. Our results demonstrated that miR-124 is a potent negative regulator of BACE1 in the cellular AD phenotype and might be involved in the pathogenesis of AD.

miR-15b represses BACE1 expression in sporadic Alzheimer’s disease

Beta-site Amyloid precursor protein Cleaving Enzyme 1 (BACE1) is conceived as a potential target for therapies against Alzheimer disease (AD). MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate gene expression in a sequence-specific manner. Although miRNAs have been increasingly recognized as important modulators in sporadic AD. In order to confirm whether miR-15b correlates ...

Cdk5 Inhibition and Aβ42 Increase Bace1 Level in Primary Neurons by a Post- Transcriptional Mechanism: Implications of Cdk5 as a Therapeutic Target for Alzheimer’s Disease*

Background: β-secretase BACE1 is elevated in Alzheimer’s disease (AD) during pathogenesis though an unknown mechanism. Result: Aβ42 increases BACE1 in primary neurons via a post-transcriptional mechanism and is synergized by Cdk5 inhibitors. Conclusion: Aβ42 increases neuronal BACE1 translation through a Cdk5-independent pathway. Significance: Amyloid may initiate a feedforward mechanism of BAC...

Expression of amyloid-associated miRNAs in both the forebrain cortex and hippocampus of middle-aged rat.

BACKGROUND Aging is associated with the gradual cognitive decline and shows the typical senile plaque formation in the brain, which results from the aggregation of beta amyloid (Aβ) peptide following the abnormal proteolytic processing of amyloid precursor protein (APP) by β-secretase (BACE1) and γ-secretase. Accumulating evidence indicates that several microRNAs (miRNAs) are involved in the Al...

Dropping the BACE: Beta Secretase (BACE1) as an Alzheimer’s Disease Intervention Target

The β-site amyloid precursor protein cleaving enzyme 1 (BACE1) is an important regulator for the production of amyloid plaques, a characteristic of the Alzheimer’s disease (AD) brain. The proteolytic cleavage of the amyloid precursor protein (APP), by BACE1, produces an insoluble amyloid-β (Aβ) fragment which has the ability to aggregate and migrate onto the dendrites and cell body of neuronal ...

Downregulated miR-29c correlates with increased BACE1 expression in sporadic Alzheimer's disease.

BACKGROUND Beta-site Amyloid precursor protein Cleaving Enzyme 1 (BACE1) is conceived as a potential target for therapies against Alzheimer disease (AD) which is characterized by the accumulation of plaques formed of short β-amyloid (APPβ) peptides. Recently, such microRNAs, as miR-29a, miR-29b-1 have been shown to correlate with abnormally high levels of BACE1 and APPβ in sporadic AD. METHOD...
