- Abstract
- The amyloid protein precursor (APP) is cleaved in its intramembranous domain by γ-secrease to generate amyloid β and a free carboxyl-terminal intracellular fragment. The carboxyl-terminal of 105 amino acids of APP (APP-C105) plays a crucial role in the neuropathology of Alzheimer's disease (AD), but it is incompletely understand how APP-C105 overexpression interacts and regulates the brain function and Aβ-42 levels, and whether or not it is associated with the expressions of GSK3β-binding proteins. To test this, transgenic mice expressing NSE-controlled APP-C105 were produced and tested for their above phenotypes. A behavioral deficit was observed in the 9 months old transgenic mice, and western blot indicated that there was a predominant expression of APP-C105 in transgenic brains compared with those of non-transgenic brains. In parallel, APP-C105 overexpression resulted in the modulation of the Aβ-42 level, γ-secretase activity, GSK3β-binding proteins including PS1, tau, and β-catenin in the brains of the transgenic mice relative to the non-transgenic mice. Thus, altered expressions of these neuropathological phenotypes in APP-C105 transgenic mice could be useful targets in developing new therapeutic treatments. © 2005 Springer Science+Business Media, Inc.
