title: Proteomic analysis of corticobasal degeneration: a case study of corticobasal degeneration at the proteome level.
abstract: Corticobasal degeneration (CBD) is an adult-onset progressive neurodegenerative disorder. However, its pathogenic mechanisms underlying this disorder remain poorly understood. The authors examined changes of proteome profiles between three nondemented comparison brains and a CBD brain based on two-dimensional gel electrophoresis. Two up-regulated proteins in the CBD brain were identified as protein-L-isoaspartate (D-aspartate) O-methyltransferase and cofilin 1 (non-muscle), and six down-regulated proteins were identified as carbonyl reductase [NADPH] 1, two of peptidyl-prolyl cis-trans isomerase A, ubiquitin carboxyl-terminal hydrolase isozyme L1, phosphoglycerate mutase 1 (brain) and chain A of human peroxiredoxin 5. Subsequently, the possible relevance of these changes was analyzed.
