Transgene: CMVAPP695sw construct, containing APPsw695, (gift of
Tae-Wan Kim). The pNSE-CAT (gift from Dr. J. Gregor Sutcliffe). NSE-APPsw
with the prokaryotic sequence eliminated, microinjected into BDF1.
Promoter: Rat NSE
Origin: C57BL/6 x DBA/2
12-month-old tg mouse brains showed increased immunostaining for Aß-42 without plaque
formations in cortex or hippocampus. In MAPK family, both JNK and p38 were activated,
whereas there was no significant activation of the ERK. Tau phosphorylation was
also enhanced in the tg relative to the control mice. Cox-2 levels, (WB and immunostaining)
and significant caspase-3- and TUNEL-stained nuclei were detected in tg mice compared
to the age-matched controls.
In the water maze tests, 12-month-old transgenic mice had longer escape latencies,
across the former platform location, than the age-matched control mice. These transgenic
mice also showed increased escape distances in finding the former platform location.
