Biomarkers discovery for progressive supranuclear palsy from the human cerebrospinal fluid using mass spectrometry-based proteomics

ABSTRACT: Progressive supranuclear palsy (PSP) is a neurodegenerative parkinsonian disorder. This study using CSF samples of PSP patients is a follow-up study to discover biomarkers related to the previous PSP brain results. This study is the first-ever attempt at an in-depth global proteomic study using more than 100 CSF samples for PSP study. In this study, we used the 11-plex isobaric tandem-mass-tag (TMT) technology for more accurate and sensitive quantification of CSF proteins and analyzed them using Orbitrap Fusion Lumos mass spectrometry on 40 PSP and 40 PD patients as well as 40 HC individuals CSF samples for the discovery experiment. These candidate biomarkers discovered in this study will pave the way for the development of reliable PSP biomarkers.
