Abstract
We developed a novel quantitative assay to test the hypothesis that defects in DNA cytosine methylation might be responsible for the brain chromatin abnormalities and transcriptional alterations observed in patients with Alzheimer's disease (AD). We found no significant difference in percent methylation of CCGG sites from brain DNA of 44 patients with AD compared with 20 normal subjects. These results, however, would not exclude genomic redistribution of methylcytosine in AD, or disturbed methylation of a limited population of critical brainβspecific genes.

Recently, the neurotoxic amyloid β€-peptide was shown to up-regulate polyamine metabolism by increasing ornithine decarboxylase (ODC) activity and polyamine uptake by initiating free radical damage in Alzheimer's disease (AD). 1 Because of these findings, polyamines have been considered to play an im
