Investigation 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 کاملAmyloid precursor proteins interact with the heterotrimeric G protein Go in the control of neuronal migration.
Amyloid precursor protein (APP) belongs to a family of evolutionarily conserved transmembrane glycoproteins that has been proposed to regulate multiple aspects of cell motility in the nervous system. Although APP is best known as the source of β-amyloid fragments (Aβ) that accumulate in Alzheimer's disease, perturbations affecting normal APP signaling events may also contribute to disease progr...
متن کاملAmyloid Precursor Protein family as unconventional Go-coupled receptors and the control of neuronal motility
Cleavage of the Amyloid Precursor Protein (APP) generates amyloid peptides that accumulate in Alzheimer Disease (AD), but APP is also upregulated by developing and injured neurons, suggesting that it regulates neuronal motility. APP can also function as a G protein-coupled receptor that signals via the heterotrimeric G protein Gαo, but evidence for APP-Gαo signaling in vivo has been lacking. Us...
متن کاملAmyloid Precursor Protein
Intracellular trafficking and proteolytic processing of amyloid precursor protein (APP) have been the focus of numerous investigations over the past two decades. APP is the precursor to the amyloid -protein (A ), the 38–43-amino acid residue peptide that is at the heart of the amyloid cascade hypothesis of Alzheimer disease (AD). Tremendous progress has been made since the initial identificatio...
متن کاملBinding of F-spondin to amyloid- precursor protein: A candidate amyloid- precursor protein ligand that modulates amyloid- precursor protein cleavage
Amyloidprecursor protein (APP), a type I membrane protein, is physiologically processed by or -secretases that cleave APP N-terminal to the transmembrane region. Extracellular -cleavage of APP generates a large secreted N-terminal fragment, and a smaller cellular C-terminal fragment. Subsequent -secretase cleavage in the transmembrane region of the C-terminal fragment induces secretion of small...
