A series of chimeric promoters for higher-level expression of foreign genes in plants was constructed as fusions of a gene for beta-glucuronidase (GUS) with the terminator of a gene for nopaline synthase (nos) or of the cauliflower mosaic virus (CaMV) 35S transcript, and the strength of these promoters was assayed in transient and stable expression systems(More)
Genetic analysis in Drosophila has shown that engrailed (en) plays an important role in segmentation and neurogenesis. A closely related gene, invected (in), is coexpressed with en in the posterior developmental compartments where en is known to specify cell state. We report here the isolation of two en-like cDNAs from the middle silk glands of Bombyx mori(More)
PURPOSE A comprehensive haplotype analysis of UGT1A1 in the Japanese population was conducted, and the effects of these haplotypes were investigated with respect to UGT1A1-related phenotypic parameters in patients with cancer who received irinotecan. METHODS The UGT1A1 gene, including the enhancer, the promoter, and all 5 exons and their flanking regions,(More)
A highly water soluble disulfonated tetrazolium salt, 4-[3-(2-methoxy-4-nitrophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate sodium salt, was synthesized. The compound is reduced by NADH in good yields at neutral pHs in the presence of 1-methoxy PMS to produce the corresponding formazan dye that absorbs at 460 nm. The formazan is soluble(More)
The possible involvement of 5-HT(4) receptors in cognitive function was investigated with a view toward modulating the cholinergic neuronal system. For this purpose, behavioral, electrophysiological, and neurochemical studies were performed in rats. The behavioral study, using a passive avoidance test, demonstrated that the 5-HT(4) receptor agonist SC 53116(More)
BACKGROUND AND OBJECTIVES Survival after surgery for intrahepatic cholangiocarcinoma (ICC) is usually poor. The objective of this study was to investigate whether the gross appearance of ICC indicates postoperative prognosis. METHODS Seventy patients with ICC underwent hepatectomy, with a 50% curative resection rate. Tumors were classified according to(More)
The skeletal effects of graded doses of prostaglandin E2 (PGE2) given to weanling Sprague-Dawley rats for 3 weeks were investigated to elucidate the role of bone cells in increasing hard tissue mass. Decalcified (3 micron) sections were quantified in the light microscope by point hit and intersect counting using a Merz grid. Hard tissue mass (bone and(More)
BACKGROUND Ghrelin is a novel growth hormone-releasing peptide that also induces vasodilation, inhibits sympathetic nerve activity, and stimulates feeding through growth hormone-independent mechanisms. We investigated the effects of ghrelin on left ventricular (LV) function, exercise capacity, and muscle wasting in patients with chronic heart failure (CHF).(More)
In order to identify genetic polymorphisms and haplotype frequencies of CYP1A2 in a Japanese population, the enhancer and promoter regions, all the exons with their surrounding introns, and intron 1 were sequenced from genomic DNA from 250 Japanese subjects. Thirty-three polymorphisms were found, including 13 novel ones: 2 in the enhancer region, 5 in the(More)
The E loci in Bombyx mori are expected to contain a homeotic gene complex specifying the identities of the larval abdominal segments. However, the molecular structure of this complex remains to be determined. We have started to analyze the structural changes in the E complex mutations. We used three newly isolated Bombyx homeobox genes as probes. These(More)
