p130Cas (Cas) has been recently identified as a 130-kDa protein that is highly phosphorylated on tyrosine residues and is stably associated with p47v-crk (v-Crk) and p60v-src (v-Src) oncogene products in cells transformed by the respective genes. Cas is a novel signaling molecule having a single Src homology (SH) 3 domain and a cluster of multiple(More)
A reduction in ankle-brachial BP index (ABPI) is associated with generalized atherosclerotic diseases and predicts cardiovascular mortality and morbidity in several patient populations. However, a large-scale analysis of ABPI is lacking for hemodialysis (HD) patients, and its use in this population is not fully validated. A cohort of 1010 Japanese patients(More)
Cell adhesion to extracellular matrix proteins is a dynamic process leading to dramatic changes in the cell phenotype. Integrins are one of the major receptor families that mediate cell-matrix contact. Evidence that integrins can act as signal transducing molecules has accumulated over the past few years. We report here that p44erk-1 and p42erk-2(More)
Integrin/ligand binding evokes tyrosine phosphorylation of various proteins. We reported previously that a 105 kD protein (pp105) was tyrosine phosphorylated by the engagement of beta 1 integrins in T lymphocytes. We show here that pp105 is a novel p130Cas (Crk-associated substrate)-related protein. Deduced amino acid sequence revealed that pp105 contains(More)
OBJECTIVE HIV-1 can use various G protein-coupled receptors (GPCRs) in addition to CCR5 and CXCR4 as coreceptors; however, this type of HIV-1 infection has hardly been detected in vivo. The objective of this study was to elucidate the spectrum of GPCR usage by HIV-1 populations in vivo. DESIGN CD4-expressing glioma cell line, NP-2/CD4, becomes highly(More)
The present study was conducted to explore renal progenitor-like cells that are actively engaged in tubular regeneration after injury. For addressing this issue, the existence of label-retaining cells (LRC; slow-cycling cells) in normal rat kidneys by in vivo bromodeoxyuridine (BrdU) labeling was examined. LRC were scattering among renal epithelial tubular(More)
CD26, the T cell activation molecule dipeptidyl peptidase IV (DPPIV), associates with a 43-kilodalton protein. Amino acid sequence analysis and immunoprecipitation studies demonstrated that this 43-kilodalton protein was adenosine deaminase (ADA). ADA was coexpressed with CD26 on the Jurkat T cell lines, and an in vitro binding assay showed that the binding(More)
OBJECTIVE In RA, response to TNF blockers may be associated with a profile of cytokine production unique to each patient. This study sought to predict the response to biologic agents by examining pro-inflammatory cytokine synthesis in stimulated whole blood cultures (WBCs). METHODS We measured the concentration of TNF-α, IL-1β and IL-6 in supernatants of(More)
We have isolated a cDNA clone for a P-450, designated P-450ib (Ichihara, K., Kusunose, E., Kaku, M., Yamamoto, S., and Kusunose, M. (1985) Biochim. Biophys. Acta 831, 99-105), from a cDNA library of rabbit small intestine mucosa by using synthetic DNA fragment by the polymerase chain reaction, as a hybridization probe. The cDNA with a 1,829-base pair insert(More)
OBJECTIVE Interleukin-22 (IL-22) is a novel cytokine of the IL-10 family. Although its pathophysiologic function is largely unknown, induction of acute-phase responses by IL-22 has suggested proinflammatory properties. In this study, we sought to examine whether IL-22 plays a role in the pathogenesis of rheumatoid arthritis (RA). METHODS Expression of(More)
