Neuronal pentraxin receptor in cerebrospinal fluid as a potential biomarker for neurodegenerative diseases

Abstract

Neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD), are characterized by progressive loss of cognitive function, dementia, and problems with movements. In order to find new protein biomarkers of high specificity from cerebrospinal fluid (CSF) of AD and PD patients, one-dimensional gel electrophoresis (1-DE) coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS) as well as 2-DE analysis were performed. In 1-DE and LC-MS/MS 371 proteins were identified, among which levels of proteins such as isoform 1 of contactin-1, contactin-2, carnosine dipeptidase 1 (CNDP1), 120 kDa isoform precursor of neural cell adhesion molecule 1 (NCAM-120), alpha-dystroglycan, secreted protein acidic and rich in cysteine-like protein 1 precursor (SPARCL1), isoform 2 of calsyntenin 1 (CLSTN1), and neuronal pentraxin receptor (NPR) showed significant changes in AD or PD CSF compared with normal subjects. In 2-DE analysis approximately 747-915 spots were detected in CSF of AD or PD patients, from which 17-24 proteins with more than a 1.2 fold change were identified by tandem MS. Most proteins identified showed consistent changes in LC-MS/MS and 2-DE analysis. Three proteins that showed significant changes were selected for further validation by Western blot analysis. While NCAM-120 and alpha-dystroglycan exhibited higher levels in both AD and PD CSF compared with normal subjects, the level of NPR was increased only in AD CSF in Western blot analysis. The results were consistent with quantitative analysis of 2-DE spots. A higher level of NPR was also found in AD serum. This study suggests that NCAM-120, alpha-dystroglycan, and NPR are candidate biomarkers in CSF for neurodegenerative diseases, and that the changes in the CSF level of NPR may be specific for AD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
