The nucleocytoplasmic transport system is essential for maintaining cell viability; transport of proteins and nucleic acids between the nucleus and the cytoplasm occurs through nuclear pore complexes (NPCs). In this study, we examined the immunohistochemical distribution of the major protein components of NPCs, Nup62, Nup88, and Nup153, in spinal cords from(More)
To investigate myonuclear alterations in sporadic inclusion body myositis (s-IBM), we immuno-localized histones in muscles in 11 patients. The examination showed that vacuolar rims were frequently positive for histone H1. In triple-color fluorescence study, the H1-positive products were found on the inner side of an emerin-positive circle with DNA.(More)
This report concerns an immunohistochemical investigation on RNA-related proteins in the basophilic inclusions (BIs) from patients with adult-onset atypical motor neuron disease. Formalin-fixed, paraffin-embedded sections of the motor cortex and the lumbar spinal cord were examined. The BIs appeared blue in color with H&E and Nissl stain, and pink with(More)
The major pathological hallmarks of amyotrophic lateral sclerosis (ALS) are neuronal cytoplasmic inclusions (NCIs) and swollen neurites. Superoxide dismutase (SOD)-1-immunopositive NCIs are observed in patients with familial ALS (FALS), and TAR DNA-binding protein 43kDa (TDP-43)-immunopositive NCIs are found in patients with sporadic ALS (SALS). Protein(More)
It has been reported that bone marrow cells (BMCs) differentiate into endothelial cells of blood vessels, and that granulocyte colony-stimulating factor (G-CSF) mobilizes progenitors in the BMCs to the peripheral blood, while macrophage colony-stimulating factor (M-CSF) augments the production of monocytes. We examined whether M-CSF augments the(More)
We investigated a family manifesting amyotrophic lateral sclerosis (ALS) with a heterozygous E478G mutation in the optineurin (OPTN) gene. Clinically, slow deterioration of motor function, mood and personality changes, temporal lobe atrophy on neuroimaging, and bizarre finger deformity were noted. Neuropathologically, TAR DNA-binding protein 43(More)
A 64-year-old man noticed weakness in his arms and dyspnea upon exertion. Four months later he was admitted to our hospital, where muscle atrophy and hyperactive deep tendon reflexes in the arms were observed upon examination. A needle electromyograph study revealed acute and chronic denervation in the extremities, and he was diagnosed as having amyotrophic(More)
A 30 year-old man with CFTD was reported. He had normal motor milestone during infancy but had been poor at sports. At 28, he experienced exertional and nocturnal dyspnea and had been diagnosed as having dilated cardiomyopathy. At 29, a cardiac pace-maker was implanted because of the complete atrio-ventricular block. Around that time, he began to notice(More)
