A number of studies have shown that increased APP levels, resulting from either a genomic locus duplication or alteration in APP regulatory sequences, can lead to development of early-onset dementias, including Alzheimer's disease (AD). Therefore, understanding how APP levels are regulated could provide valuable insight into the genetic basis of AD and(More)
Transgenic models of Alzheimer's disease (AD) have made significant contributions to our understanding of AD pathogenesis, and are useful tools in the development of potential therapeutics. The fruit fly, Drosophila melanogaster, provides a genetically tractable, powerful system to study the biochemical, genetic, environmental, and behavioral aspects of(More)
BACKGROUND A central event in Alzheimer's disease (AD) is the regulated intramembraneous proteolysis of the beta-amyloid precursor protein (APP), to generate the beta-amyloid (Abeta) peptide and the APP intracellular domain (AICD). Abeta is the major component of amyloid plaques and AICD displays transcriptional activation properties. We have taken(More)
