Fermented papaya preparation attenuates beta-amyloid precursor protein:
beta-amyloid-mediated copper neurotoxicity in beta-amyloid precursor protein
and beta-amyloid precursor protein Swedish mutation overexpressing SH-SY5Y
cells.
Recent studies indicate that the deposition of beta-amyloid (Abeta) is
related in the pathogenesis of Alzheimer's disease (AD), but the underlying
mechanism is still not clear. The abnormal interactions of Abeta with metal
ions such as copper are implicated in the process of Abeta deposition and
oxidative stress in AD brains. In the present study, we established a new
AD model, using which we found that copper triggered the Abeta neurotoxicity
in SH-SY5Y cells overexpressing the Swedish mutant form of human APP (APPsw)
in a concentration dependent manner. Fermented papaya preparation (FPP)
has shown high free radical scavenging ability in vivo and in vitro. FPP
post-treatment increased cell viability and decreased the intracellular
[Ca2+]i, reactive oxygen species (ROS) generation such as hydroxyl free
radical and superoxide anion and nitric oxide (NO) accumulation in the
cell. Our results also show that FPP prevents the cell apoptosis through
bax/bcl-2 sensitive pathway.
