A new gene, termed klotho, has been identified that is involved in the suppression of several ageing phenotypes. A defect in klotho gene expression in the mouse results in a syndrome that resembles human ageing, including a short lifespan, infertility, arteriosclerosis, skin atrophy, osteoporosis and emphysema. The gene encodes a membrane protein that(More)
We previously found that a polymer conjugated to the anticancer protein neocarzinostatin, named smancs, accumulated more in tumor tissues than did neocarzinostatin. To determine the general mechanism of this tumoritropic accumulation of smancs and other proteins, we used radioactive (51Cr-labeled) proteins of various molecular sizes (Mr 12,000 to 160,000)(More)
A dose-escalation study of cisplatin (CDDP) combined with S-1, a new oral dihydropyrimidine dehydrogenase inhibitory fluoropyrimidine, was performed to determine the maximum-tolerated dose (MTD), recommended dose (RD), dose-limiting toxicities (DLTs), and objective response rate (RR) in advanced gastric cancer (AGC). S-1 was given orally at 40 mg m(-2)(More)
Most solid tumors possess unique pathophysiological characteristics that are not observed in normal tissues or organs, such as extensive angiogenesis and hence hypervasculature, defective vascular architecture, impaired lymphatic drainage/recovery system, and greatly increased production of a number of permeability mediators. The phenomenon now known as the(More)
CLC-K1 is a kidney-specific chloride channel that mediates transepithelial chloride transport in the thin ascending limb of Henle's loop (tAL) in the inner medulla. Transport of NaCl in the tAL is thought to be a component of urinary concentration in a passive model of the countercurrent multiplication system, but there has been no direct evidence that(More)
Inactivation of the klotho (kl) gene in mice results in multiple disorders that resemble human aging. The mouse kl gene encodes a novel single-pass membrane protein with homology to beta-glucosidases. In this study, we have isolated a human homologue of the kl gene and determined its gene structure. The human kl gene is composed of 5 exons and ranges over(More)
OBJECTIVE To determine the prevalence of obesity and reference percentile curves of body mass index (BMI; kg/m2) in Japanese adults. DESIGN Cross-sectional nationwide surveys (The National Nutrition Survey, Japan) carried out in 1990-1994. A sample of 23,556 males and 28,751 females aged 15-84 y was used for this analysis. RESULTS The prevalence of(More)
With increasing emphasis on the early detection of cancer, the search is on for reliable markers that will be clinically helpful in the diagnosis of small tumours and in the assessment of their metastatic potential. This report presents evidence that an abnormal pattern of activity of the CD44 gene is a promising candidate for both of these purposes in(More)
BACKGROUND Endothelin (ET)-1 and norepinephrine (NE) are involved in myocardial ischemia/reperfusion injury. We investigated the role of ET-1 in ischemia/reperfusion-induced NE overflow and cardiac dysfunction using a selective ET(A) receptor antagonist (ABT-627), a selective ET(B) receptor antagonist (A-192621), and the spotting lethal (sl) rat, which(More)
We previously established a novel mouse model for human aging and identified the genetic foundation responsible for it. A defect in expression of a novel gene, termed klotho (kl), leads to a syndrome resembling human aging in mice. The kl gene encodes a single-pass membrane protein whose extracellular domain carries homology to beta-glucosidases. In this(More)
