Isoform-specific dysregulation of AMP-activated protein kinase signaling in a non-human primate model of Alzheimer's disease.

ABSTRACT: AMP-activated protein kinase (AMPK) is a molecular sensor that is critical for the maintenance of cellular energy homeostasis, disruption of which has been indicated in multiple neurodegenerative diseases including Alzheimer's disease (AD). Mammalian AMPK is a heterotrimeric complex and its enzymatic α subunit exists in two isoforms: AMPKα1 and AMPKα2. Here we took advantage of a recently characterized non-human primate (NHP) model with sporadic AD-like neuropathology to explore potential relationships between AMPK signaling and AD-like neuropathology. Subjects were nine female vervet monkeys aged 19.5 to 23.4 years old. Subjects were classified into three groups, control lacking AD pathology (n = 3), moderate AD pathology (n = 3), and more severe AD Pathology (n = 3). We found increased a
