Oxidative stress affects processing of amyloid precursor protein in vascular endothelial cells
BACKGROUND Oxidative stress is thought to be a key player in the pathogenesis of neurodegenerative dementia, including Alzheimer's disease (AD). It has been assumed that oxidative stress contributes to the ß-amyloid deposition in cerebral blood vessels. METHODS In order to prove this hypothesis, we examined the effect of oxidative stress on the processing of amyloid precursor protein (APP) in...
متن کاملInvestigation of the Iron Oxide Nanoparticle Effects on Amyloid Precursor Protein Processing in Hippocampal Cells
Introduction: Iron oxide nanoparticles (Fe2O3-NPs) are small magnetic particles that widely used in different aspects of biology and medicine in modern life. Fe2O3-NP accumulated in the living cells due to absence of active system to excrete the iron ions so damages cellular organelles by highly reactivity. Method: Herein cytotoxic effects of Fe2O3-NP with 50 nm size were investigated on prima...

متن کاملNicorandil inhibits oxidative stress and amyloid-β precursor protein processing in SH-SY5Y cells overexpressing APPsw.
It has been demonstrated that ATP-sensitive potassium (KATP) channel activation has neuroprotective effects against neuronal damage induced by hypoxia, ischemia or metabolism stress. This study investigated the multiply protective effects of KATP channel opener nicorandil against neurotoxicity in SH-SY5Y cells transiently transfected with Swedish mutant APP (APPsw) and also the potential involv...
متن کاملAltered Processing of Amyloid Precursor Protein in Cells Undergoing Apoptosis
Altered proteolysis of amyloid precursor protein is an important determinant of pathology development in Alzheimer's disease. Here, we describe the detection of two novel fragments of amyloid precursor protein in H4 neuroglioma cells undergoing apoptosis. Immunoreactivity of these 25-35 kDa fragments to two different amyloid precursor protein antibodies suggests that they contain the amyloid-β ...
