We found that vimentin, the most widely expressed intermediate filament protein, served as an excellent substrate for Rho-associated kinase (Rho-kinase) and that vimentin phosphorylated by Rho-kinase lost its ability to form filaments in vitro. Two amino-terminal sites on vimentin, Ser38 and Ser71, were identified as the major phosphorylation sites for(More)
Apoptosis induced by cadmium has been shown in many tissues in vivo and in cultured cells in vitro. However, its molecular mechanism is not fully understood. When the human histiocytic lymphoma cell line U937 was treated with cadmium for 12 h, evidence of apoptotic features, including change in nuclear morphology, DNA fragmentation, formation of DNA ladder(More)
Multidrug and toxin extrusion 1 (MATE1) and MATE2-K are H(+)/organic cation exchangers mediating the efflux of cationic drugs into the urine. N-methylnicotinamide (NMN) was found to be an endogenous substrate of MATE1 (Michaelis constant (K(m)) 301 ± 18 µmol/l) and MATE2-K (K(m) 422 ± 63 µmol/l) as well as a basolateral influx transporter, organic cation(More)
OBJECTIVES To determine the primary site and incidence of lymph node metastases in urothelial carcinoma of the upper urinary tract. METHODS From January 1989 to October 2005, we treated 181 patients with urothelial carcinoma of the upper urinary tract. The findings of the imaging studies when lymph node metastasis was diagnosed and the pathologic(More)
Glial fibrillary acidic protein (GFAP), the intermediate filament component of astroglial cells, can serve as an excellent substrate for both cAMP-dependent protein kinase and protein kinase C, in vitro. GFAP phosphorylated by each protein kinase does not polymerize, and the filaments that do polymerize tend to depolymerize after phosphorylation.(More)
A restriction fragment length polymorphism analysis of nuclear ribosomal RNA genes (rDNA) was used to measure the amount and distribution of genetic variability in populations of the Japanese pear pathotype of Alternaria alternata on both micro- and macrogeographical scales. A total of 322 isolates were obtained from 13 areas in Aichi, Gifu, and Tottori(More)
BACKGROUND The introduction of solid-phase immunoassay (SPI) technology for the detection and characterization of human leukocyte antigen (HLA) antibodies in transplantation while providing greater sensitivity than was obtainable by complement-dependent lymphocytotoxicity (CDC) assays has resulted in a new paradigm with respect to the interpretation of(More)
ATP-sensitive potassium (K(ATP)) channels, composed of sulfonylurea receptor (SURx) and Kir6.x, play important roles by linking cellular metabolic state to membrane potential in various tissues. Pancreatic, cardiac, and vascular smooth muscle K(ATP) channels, which consist of different subtypes of SURx, differ in their responses to cellular metabolic state.(More)
PURPOSE We determined the impact of the extent of regional lymphadenectomy on survival in patients with urothelial carcinoma of the upper urinary tract. MATERIALS AND METHODS Between January 1989 and January 2006, 169 patients with nonmetastatic urothelial carcinoma of the upper urinary tract underwent curative surgery. We previously reported the primary(More)
