In sum, we have shown that Sepw1 expression is abundant in several mouse brain regions, including pyramidal neurons of cortex and hippocampus, and Purkinje cells of cerebellum. We also showed Sepw1 expression in neuronal processes, especially apical dendrites, and some colocalization with tubulin. Analysis of isolated nerve terminals further revealed the presence of Sepw1 and much of the selenoprotein synthesis machinery in synaptic compartments. Inhibitors,research,lifescience,medical Sepw1 expression was drastically reduced
in hippocampus and synaptosomes in Sepp1−/− mice. Lastly, Sepw1 mRNA associates with Stau2 in SH-SY5Y neuroblastoma cells. Combined with previous reports documenting Sepw1 mRNA expression in neuronal processes, translational regulation of Sepw1 expression in synaptic compartments is probable and warrants further investigation.

We investigated a series of 27 patients admitted with an unilateral ischemic stroke affecting the IC (Table (Table1).1). As vascular lesions affecting exclusively the IC are extremely rare, we sampled patients with circumscribed damage predominantly to the insular and the opercular peri-IC, Inhibitors,research,lifescience,medical which was documented by magnetic resonance imaging (MRI) (13 Epacadostat female, 14 male; mean age 65 years; standard deviation [SD] 12 years) (Fig. (Fig.1A1A and B). Mean time between Inhibitors,research,lifescience,medical stroke and testing was 7 days (SD 4 days). Patients with diffuse brain damage or severe communication deficits due to aphasia were excluded. Neglect was assessed in 16 patients by the standardized test battery of SPTLC1 the German version of the Behavioural
Inattention Test (Fels and Geissner 1987) and in five patients by the bells test (Gauthier et al. 1989). In two of the right-sided and four of the left-sided patients neglect was not tested. Only one patient with right-sided infarction showed neglect. In addition to the actual study, we reanalyzed previous already existing data from 20 patients to show whether there might be an interaction between somatosensory and vestibular parameters (B. Baier, P. zu Eulenburg, C. Geber, R. Rohde, R. Rolke, C. Maihöfner, F. Birklein, M. Dieterich, unpubl. ms; Dieterich and Brandt 1993; Brandt et al. 1994; Rolke et al. 2006). The study was carried out in accordance with the ethical standards laid out in the 1962 Declaration of Helsinki.
