Abstract
Background: MicroRNA (miR)-125a-3p is reported to play an important role in some central nervous system diseases, such as Alzheimer’s disease (AD). However, a study has not been conducted on the mechanism of miR-125a-3p in the pathological process of AD.
Methods: First, we assessed the expression of miR-125a-3p in AD cohort. Subsequently, we altered the expressions of miR-125a-3p to assess its role in cell viability, cell apoptosis, amyloid-β (Aβ) metabolism, and synaptic activity. Finally, we identified its potential mechanism underlying AD pathology.
Results: This study unveiled the potential function of miR-125a-3p through modulating amyloid precursor protein processing. Additionally, miR-125a-3p influenced cell survival and activated synaptic expression through the modulation of Aβ metabolism in the mitogen-activated protein kinase (MAPK) pathway via fibroblast growth factor receptor 2.
Conclusion: Our study indicates that targeting miR-125a-3p may be an applicable therapy for AD in the future. However, more in vitro and in vivo studies with more samples are needed to confirm these results.
Keywords: Alzheimer’s disease, miR-125a-3p, Aβ, fibroblast growth factor receptor 2, MAPK pathway, MicroRNA.
