Modification Details

Transgene consisting of the signal plus 99-amino acid carboxyl-terminal sequence (SbC) of human APP under the control of a cytomegalovirus enhancer/β-actin promoter.


Although the transgene is expressed in brain and skeletal muscle, no neuropathology was found in transgenic mice up to age 29 months (Fukuchi et al., 1996). Pathology reminiscent of inclusion body myopathy observed at 6-12 months: Aβ-immunoreactive deposits in skeletal muscle fibers. Muscle fibers with Aβ-immunoreactive deposits increased with age and also became vacuolated (Fukuchi et al., 1998).


Hypoactivity. The acquisition of place learning in the Morris water maze task was impaired (Lalonde et al., 2002).

Other Phenotypes

Higher cytochrome oxidase activity in thalamic nuclei (Strazielle et al., 2004). High levels of Aβ peptides in the plasma (Fukuchi et al., 1996).
