Abstract

Oxidative stress, manifested by protein oxidation, lipid peroxidation, DNA oxidation and 3-nitrotyrosine formation, among other indices, is observed in Alzheimer's disease (AD) brain. Amyloid beta-peptide (1-42) [Abeta(1-42)] may be central to the pathogenesis of AD. Our laboratory and others have implicated Abeta(1-42)-induced free radical oxidative stress in the neurodegeneration observed in AD brain. This paper reviews some of these studies from our laboratory. Recently, we showed both in-vitro and in-vivo that methionine residue 35 (Met-35) of Abeta(1-42) was critical to its oxidative stress and neurotoxic properties. Because the C-terminal region of Abeta(1-42) is helical, and invoking the i + 4 rule of helices, we hypothesized that the carboxyl oxygen of lle-31, known to be within a van der Waals distance of the S atom of Met-35, would interact with the latter. This interaction could alter the susceptibility for oxidation of Met-35, i.e. free radical formation. Consistent with this hypothesis, substitution of lle-31 by the helix-breaking amino acid, proline, completely abrogated the oxidative stress and neurotoxic properties of Abeta(1-42). Removal of the Met-35 residue from the lipid bilayer by substitution of the negatively charged Asp for Gly-37 abrogated oxidative stress and neurotoxic properties of Abeta(1-42). The free radical scavenger vitamin E prevented A(beta (1-42)-induced ROS formation, protein oxidation, lipid peroxidation, and neurotoxicity in hippocampal neurons, consistent with our model for Abeta-associated free radical oxidative stress induced neurodegeneration in AD. ApoE, allele 4, is a risk factor for AD. Synaptosomes from apoE knock-out mice are more vulnerable to Abeta-induced oxidative stress (protein oxidation, lipid peroxidation, and ROS generation) than are those from wild-type mice. We also studied synaptosomes from allele-specific human apoE knock-in mice. Brain membranes from human apoE4 mice have greater vulnerability to Abeta(1-42)-induced oxidative stress than brain membranes from apoE2 or E3, assessed by the same indices, consistent with the notion of a coupling of the oxidative environment in AD brain and increased risk of developing this disorder. Using immunoprecipitation of proteins from AD and control brain obtained no longer than 4h PMI, selective oxidized proteins were identified in the AD brain. Creatine kinase (CK) and beta-actin have increased carbonyl groups, an index of protein oxidation, and Glt-1, the principal glutamate transporter, has increased binding of the lipid peroxidation product, 4-hydroxy-2-nonenal (HNE). Abeta inhibits CK and causes lipid peroxidation, leading to HNE formation. Implications of these findings relate to decreased energy utilization, altered assembly of cytoskeletal proteins, and increased excitotoxicity to neurons by glutamate, all reported for AD. Other oxidatively modified proteins have been identified in AD brain by proteomics analysis, and these oxidatively-modified proteins may be related to increased excitotoxicity (glutamine synthetase), aberrant proteasomal degradation of damaged or aggregated proteins (ubiquitin C-terminal hydrolase L-1), altered energy production (alpha-enolase), and diminished growth cone elongation and directionality (dihydropyrimindase-related protein 2). Taken together, these studies outlined above suggest that Met-35 is key to the oxidative stress and neurotoxic properties of Abeta(1-42) and may help explain the apoE allele dependence on risk for AD, some of the functional and structural alterations in AD brain, and strongly support a causative role of Abeta(1-42)-induced oxidative stress and neurodegeneration in AD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
