Expression of the Arabidopsis CGS1 gene that codes for cystathionine gamma-synthase is feedback regulated at the step of mRNA stability in response to S-adenosyl-L-methionine (AdoMet). A short stretch of amino acid sequence, called the MTO1 region, encoded by the first exon of CGS1 itself is involved in this regulation. Here, we demonstrate, using a(More)
The effect of polaprezinc, a chelate compound consisting of zinc ion and L-carnosine, on abnormalities of taste sensation induced by feeding a zinc-deficient diet to rats was examined by using the two-bottle preference test (quinine hydrochloride as a bitter taste and sodium chloride as a salty taste). Rats were fed either a zinc-deficient or a(More)
To clarify the exact anti-arthritic action mechanisms of chondroitin sulfate (CS), we evaluated the effects of CS derived from shark cartilage (CS-SC) composed mainly of chondroitin-6-sulfate and porcine trachea cartilage (CS-PC) composed mostly of chondrotin-4-sulfate on the functions of human articular chondrocytes and synovial fibroblasts. Both CS-SC and(More)
Gastrin is known to enhance the growth of pancreatic carcinoma via the cholecystokinin (CCK)-2/gastrin receptor. We investigated the anti-tumor effect of Z-360 (calcium bis [(R)-(−)-3-[3-{5-cyclohexyl-1-(3,3-dimethyl-2-oxo-butyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl}ureido]benzoate]), a novel orally active CCK-2 receptor antagonist alone(More)
The bioavailability of a series of novel acylated ascorbic acid derivatives, 6-O-acyl-2-O-alpha-D-glucopyranosyl-L-ascorbic acids (6-Acyl-AA-2G), as an ascorbic acid (AA) supplement was investigated in rats and guinea pigs. Oral administration of 6-Acyl-AA-2G to rats resulted in an increase in the plasma AA level. However, the intact form was not detectable(More)
The Arabidopsis thaliana CGS1 gene encodes cystathionine gamma-synthase, the first committed enzyme of methionine biosynthesis in higher plants. Expression of CGS1 is feedback-regulated at the step of mRNA degradation in response to S-adenosyl-L-methionine (AdoMet). A short stretch of amino acid sequence, termed the MTO1 region, encoded within the first(More)
We have isolated a part of the gene for the pituitary glycoprotein hormone common alpha subunit (PGHalpha) and the whole gene for the follicle-stimulating hormone beta subunit (FSHbeta) in the Japanese crested ibis (Nipponia nippon), a critically endangered bird species in East Asia. The nucleotide sequence of a part of the PGHalpha gene (5026 bp) contained(More)
We isolated a putative gene for the thyrotropin beta subunit (TSHbeta) from two types of genomic libraries of the Japanese crested ibis, Nipponia nippon. Exon-intron structure was deduced by comparing the determined sequence with those of TSH beta cDNA of other birds. The deduced amino acid sequence shows extensive similarities to those of the other birds,(More)
A 25-year-old woman with ulcerative colitis developed heart failure due to severe aortic regurgitation. Although chest X-ray 18 months previously showed a normal cardiac shadow, thoracic aortic aneurysm progressed due to Takayasu arteritis. Aortic valve and ascending aorta replacement were performed successfully, but re-valve replacement for severe aortic(More)
A 60-year-old woman presented with acute pulmonary edema followed by cardiopulmonary arrest due to idiopathic ventricular fibrillation. Owing to immediate cardioversion, her electrocardiogram showed sinus rhythm and echocardiography did not show any wall motion abnormalities. The next day, echocardiographic re-examination was characterized by akinesis of(More)
