ABSTRACT
Objective@#To search for biomarkers for human familial prion disease.@*Methods@#Two-dimensional differential gel electrophoresis (2D-DIGE) proteomic analysis has been performed in frontal lobe tissues of 3 patients suffering from human familial prion disease (PrP) and 3 age-and sex-matched patients suffering from sudden death due to heart failure without neurological disease.@*Results@#The maps revealed 14 polypeptide chains differentially modulated in the PrP samples, among those, 7 could be identified upon digestion and MALDI-TOF/MS analysis, of which 6 appeared to be up-regulated, 1 being down-regulated.@*Conclusions@#We highlight Galectin-1(Gal-1), ryanodine receptor 2 (RyR2), ubiquitin, Rab-interacting lysosomes protein-like protein 1 (RILPL-1) profillin 2 (PFN2), in the differential map. These proteins are related to neurogenesis, the clearance of misfolded proteins, stasis of calium channel, myoclonus and so on. These proteins are potential biomarkers or targets for treatment of prion disease.
