BACKGROUND Several promising molecular-targeted drugs are used for advanced renal cancers. However, complete remission is rarely achieved, because none of the drugs targets a key molecule that is specific to the cancer, or is associated with "oncogene addiction" (dependence on one or a few oncogenes for cell survival) of renal cancer. Recently, an(More)
PURPOSE The anaplastic lymphoma kinase (ALK) inhibitor crizotinib has been used in patients with lung cancer or inflammatory myofibroblastic tumor (IMT), both types harboring ALK fusions. However, detection of some ALK fusions is problematic with conventional anti-ALK immunohistochemistry because of their low expression. By using sensitive(More)
Apple latent spherical virus (ALSV) vectors were evaluated for virus-induced gene silencing (VIGS) of endogenous genes among a broad range of plant species. ALSV vectors carrying partial sequences of a subunit of magnesium chelatase (SU) and phytoene desaturase (PDS) genes induced highly uniform knockout phenotypes typical of SU and PDS inhibition on model(More)
The promising results of anaplastic lymphoma kinase (ALK) inhibitors have changed the significance of ALK fusions in several types of cancer. These fusions are no longer mere research targets or diagnostic markers, but they are now directly linked to the therapeutic benefit of patients. However, most available tumor tissues in clinical settings are(More)
Spinocerebellar ataxia type 31 (SCA31) is an autosomal-dominant cerebellar ataxia showing a Purkinje cell (PC)-predominant neurodegeneration in humans. The mutation is a complex penta-nucleotide repeat containing (TGGAA)n , (TAGAA)n , (TAAAA)n and (TAGAATAAAA)n inserted in an intron shared by two different genes BEAN1 and TK2 located in the long arm of the(More)
Although Toll-like receptors (TLRs) in mammals are well-known to play important roles in innate immunity, newer roles for the TLRs have suggested that cells with aberrant TLR expression may have a survival advantage over normal cells. Lymphocytes are one of a small number of cell types that express many of the TLRs, suggesting that abnormal TLR(More)
PURPOSE To evaluate associations of Ki-67 expression with oncologic outcomes in muscle-invasive bladder cancer (MIBC) patients treated with chemoradiotherapy (CRT)-based bladder-sparing protocol. MATERIALS AND METHODS Between 1998 and 2011, 190 consecutive MIBC patients were treated with CRT-based bladder-sparing protocol. After transurethral resection of(More)
As research into hematopoiesis advances, new factors associated with hematopoietic stem cell (HSC) activity have been discovered, and the contribution of HSC factors to hematopoiesis is now actively being investigated. Since the involvement of stem cells is considered to be important in hematological malignancies as well as normal hematopoiesis, we examined(More)

cal – chest XP and CT revealed no lesion affecting the recurrent and/or vagus nerves. The family’s consent to perform tracheotomy was not obtained. At the age of 89, he was admitted to our hospital with pyrexia. On admission, neurological examination revealed new findings including right-sided dominant rigidity and Myerson’s sign. Resting tremor was absent.(More)
