Abstract

Estrogen-related receptor alpha (ERRα) is a transcriptional factor associated with mitochondrial biogenesis and energy metabolism. However, little is known about the role of ERRα in Alzheimer's disease (AD). Here, we report that in APP/PS1 mice, an animal model of AD, ERRα protein and mRNA were decreased in a region- and age-dependent manner. In HEK293 cells that stably express human full-length β-amyloid precursor protein (APP), overexpression of ERRα inhibited the amyloidogenic processing of APP and consequently reduced Aβ1-40/1-42 level. ERRα overexpression also attenuated Tau phosphorylation at selective sites, with the concomitant reduction of glycogen synthase kinase 3β (GSK3β) activity. Interestingly, alterations of APP processing and Tau phosphorylation induced by hydrogen peroxide were reversed by ERRα overexpression in HEK/APP cells. These results indicated that ERRα plays a functional role in AD pathology. By attenuating both amyloidogenesis and Tau phosphorylation, ERRα may serve as a potential therapeutic target for AD.
