Although thousands of long noncoding RNAs (lncRNAs) are localized in the nucleus, only a few dozen have been functionally characterized. Here we show that nuclear enriched abundant transcript 1 (NEAT1), an essential lncRNA for the formation of nuclear body paraspeckles, is induced by influenza virus and herpes simplex virus infection as well as by Toll-like(More)
Transcription and replication of the influenza virus RNA genome occur in the nuclei of infected cells through the viral RNA-dependent RNA polymerase consisting of PB1, PB2, and PA. We previously identified a host factor designated RAF-1 (RNA polymerase activating factor 1) that stimulates viral RNA synthesis. RAF-1 is found to be identical to Hsp90. Here,(More)
Influenza virus RNA-dependent RNA polymerase is a multi-functional heterotrimer, which uses a 'cap-snatching' mechanism to produce viral mRNA. Host cell mRNA is cleaved to yield a cap-bearing oligonucleotide, which can be extended using viral genomic RNA as a template. The cap-binding and endonuclease activities are only activated once viral genomic RNA is(More)
PURPOSE Our previous results for treatment of hepatocellular carcinoma with proton beam therapy (PBT) revealed excellent local control. In this study, we focused on the impact of PBT on normal liver function. METHODS AND MATERIALS The subjects were 259 patients treated with PBT at the University of Tsukuba between January 2001 and December 2007. We(More)
HIF-1 is active in hypoxia, such as inflamed mucosa, and HIF-1 in epithelium has been reported to control inflamed mucosa in IBD models. Although T cells play an important role for pathogenesis of IBD, the function of HIF-1 in T cells remains to be elucidated. We aimed to clarify the function of HIF-1 in T cells in IBD with focus on the balance between Treg(More)
BACKGROUND Previous comparative reports of stereotactic body radiotherapy (SBRT) and surgery for non-small cell lung cancer (NSCLC) suffered from short follow-up, mixed extents of resection and inclusion of benign lesion. We aimed to make comparisons of long-term outcomes between a pure series of video-assisted thoracoscopic surgery (VATS) lobectomy and(More)
Immunological responses in the host can result in different disease outcomes of Helicobacter pylori-induced gastritis. Prostaglandin E2 derived from cyclooxygenase (COX) and prostaglandin E synthase contribute to gastric protection. Recently, prostaglandin D2 was shown to be involved in host immunity by chemotactic activity through chemoattractant(More)
We report a case of an 80-year-old woman with dropped head syndrome associated with cervical spondylotic myelopathy. She could not keep her cervical spine in a neutral position for >1 minute. She had a disturbed gait and severe kyphotic deformity in her thoracic spine. Magnetic resonance imaging revealed severe compression of the spinal cord due to cervical(More)
Magnetic resonance imaging (MRI) data is an invaluable tool in brain morphology research. Here, we propose a novel statistical method for investigating the relationship between clinical characteristics and brain morphology based on three-dimensional MRI data via radial basis function-sparse partial least squares (RBF-sPLS). Our data consisted of MRI image(More)
PURPOSE Programmed death-1 (PD-1), a coinhibitory immune signal receptor expressed in T cells, binds to PD-1 ligand and regulates antitumor immunity. Nivolumab is an anti-PD-1 antibody that blocks PD-1 signaling. We assessed the safety and antitumor activity of nivolumab in patients with platinum-resistant ovarian cancer.
