D. Pratico et al., Increased 8,12-iso-iPF(2 alpha)-VI in Alzheimer's disease: Correlation of a noninvasive index of lipid peroxidation with disease severity, ANN NEUROL, 48(5), 2000, pp. 809-812
The isoprostane 8,12-iso-iPF(2 alpha)-VI is a sensitive and specific marker
of in vivo lipid peroxidation. We found elevated levels in the urine, bloo
d and cerebrospinal fluid of patients with Alzheimer's disease (AD) that co
rrelated with measures of cognitive and functional impairment, established
biomarkers of AD pathology (cerebrospinal fluid tau and amyloid) and the nu
mber of apolipoprotein E epsilon4 alleles. These results suggest that 8,12-
iso-iPF(2 alpha)-VI is a useful biomarker of oxidative damage in AD.
