TLDR
The cytotoxic action of A beta on neurons results from free radical damage to susceptible cells, suggesting that A beta activates a member of this class of enzymes.About:

Journal ArticleDOI
Free Radicals in the Physiological Control of Cell Function
TL;DR: There is growing evidence that aging involves, in addition, progressive changes in free radical-mediated regulatory processes that result in altered gene expression.
Journal ArticleDOI
Alzheimer's Disease: Genes, Proteins, and Therapy
TL;DR: Evidence that the presenilin proteins, mutations in which cause the most aggressive form of inherited AD, lead to altered intramembranous cleavage of the beta-amyloid precursor protein by the protease called gamma-secretase has spurred progress toward novel therapeutics and provided discrete biochemical targets for drug screening and development.
Journal ArticleDOI
THE NF-κB AND IκB PROTEINS: New Discoveries and Insights
TL;DR: The transcription factor NF-κB has attracted widespread attention among researchers in many fields based on its unusual and rapid regulation, the wide range of genes that it controls, its central role in immunological processes, the complexity of its subunits, and its apparent involvement in several diseases.
Journal ArticleDOI
Activators and target genes of Rel/NF-kappaB transcription factors.
TL;DR: It is argued that NF-κB functions more generally as a central regulator of stress responses and pairing stress responsiveness and anti-apoptotic pathways through the use of a common transcription factor may result in increased cell survival following stress insults.
Journal ArticleDOI
Neurodegenerative diseases and oxidative stress.
TL;DR: Oxidative stress has been implicated in the progression of Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis and different strategies, including novel metal–protein attenuating compounds aimed at a variety of targets have shown promise in clinical studies.

Journal ArticleDOI
Mutations in Cu/Zn superoxide dismutase gene are associated with familial amyotrophic lateral sclerosis
TL;DR: Tight genetic linkage between FALS and a gene that encodes a cytosolic, Cu/Zn-binding superoxide dismutase (SOD1), a homodimeric metalloenzyme that catalyzes the dismutation of the toxic superoxide anion O–2 to O2 and H2O2 is reported.
Journal ArticleDOI
Oxidants, antioxidants, and the degenerative diseases of aging
TL;DR: It is argued that this damage to DNA, protein, and lipid is a major contributor to aging and to degenerative diseases of aging such as cancer, cardiovascular disease, immune-system decline, brain dysfunction, and cataracts.
Journal ArticleDOI
Establishment of a noradrenergic clonal line of rat adrenal pheochromocytoma cells which respond to nerve growth factor.
TL;DR: A single cell clonal line which responds reversibly to nerve growth factor (NGF) has been established from a transplantable rat adrenal pheochromocytoma and should be a useful model system for neurobiological and neurochemical studies.

TL;DR: A locus segregating with familial Alzheimer's disease (AD) has been mapped to chromosome 21, close to the amyloid precursor protein (APP) gene as discussed by the authors, which suggests that some cases of AD could be caused by mutations in the APP gene.
