Plain-language summary
Nitric oxide (NO) has been implicated in the pathophysiology of a number of neurodegenerative diseases including Alzheimer's disease (AD). In the present study, using a proteomics approach, we identified enolase, glyceraldehyde-3-phosphate dehydrogenase, ATP synthase alpha chain, carbonic anhydrase-II, and voltage-dependent anion channel-protein as the targets of nitration in AD hippocampus, a region that shows a extensive deposition of amyloid beta-peptide, compared with the age-matched control brains. Immunoprecipitation and Western blotting techniques were used to validate the correct identification of these proteins. Our results are discussed in context of the role of oxidative stress as one of the important mechanisms of neurodegeneration in AD.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
