Progressive supranuclear palsy (PSP) is a rare neurodegenerative disease for which the genetic contribution is incompletely understood. We conducted a joint analysis of 5,523,934 imputed SNPs in two newly-genotyped progressive supranuclear palsy cohorts, primarily derived from two clinical trials (Allon davunetide and NNIPPS riluzole trials in PSP) and a previously published genome-wide association study (GWAS), in total comprising 1646 cases and 10,662 controls of European ancestry. We identified 5 associated loci at a genome-wide significance threshold Pโ<โ5โรโ10 In total, we identified 6 additional significant or suggestive SNP associations with PSP, and discovered genetic overlap with other neurodegenerative diseases. These findings clarify the pathogenesis and genetic architecture of PSP. Show less
We aimed to identify disease-related biomarkers in CIDP. Using the two-dimensional difference in gel electrophoresis (2-D-DIGE), we compared CSF from patients with CIDP (n = 11) and controls (n = 11). Show more
We aimed to identify disease-related biomarkers in CIDP. Using the two-dimensional difference in gel electrophoresis (2-D-DIGE), we compared CSF from patients with CIDP (n = 11) and controls (n = 11). Protein spots that showed a significant difference were further analyzed by MALDI-TOF mass spectrometry. We identified 10 proteins that were upregulated in CIDP (two transferrin isoforms, alpha-1 acid glycoprotein 1 precursor, apolipoprotein A IV, two haptoglobin isoforms, transthyretin (TTR), retinol binding protein and two isoforms of proapolipoprotein) and 1 protein that was downregulated (integrin beta 8). The pathophysiological role of these proteins remains to be clarified by further studies. Show less
