To examine whether downregulation of NSun2 is a common event among other tauopathies we performed NSun2 Western blot analysis using brain samples from Primary Age-Related Tauopathy (PART) with dementia [22], Progressive Supranuclear Palsy (PSP) [30, 81] and control cases (Table 1; Supplementary Table 1, online resource; Fig. 2). Here, NSUN2 is linked to Classical progressive supranuclear palsy.
