Abstract : Kitasatospora setae NBRC 14216(T) (=KM-6054(T)) is known to produce setamycin (bafilomycin B1) possessing antitrichomonal activity. The genus Kitasatospora is morphologically similar to the genus Streptomyces, although they are distinguishable from each other on the basis of cell wall composition and the 16S rDNA sequence. We have determined the complete genome sequence of K. setae NBRC 14216(T) as the first Streptomycetaceae genome other than Streptomyces. The genome is a single linear chromosome of 8,783,278 bp with terminal inverted repeats of 127,148 bp, predicted to encode 7569 protein-coding genes, 9 rRNA operons, 1 tmRNA and 74 tRNA genes. Although these features resemble those of Streptomyces, genome-wide comparison of orthologous genes between K. setae and Streptomyces revealed smaller extent of synteny. Multilocus phylogenetic analysis based on amino acid sequences unequivocally placed K. setae outside the Streptomyces genus. Although many of the genes related to morphological differentiation identified in Streptomyces were highly conserved in K. setae, there were some differences such as the apparent absence of the AmfS (SapB) class of surfactant protein and differences in the copy number and variation of paralogous components involved in cell wall synthesis.

Abstract : A filamentous non-N(2)-fixing cyanobacterium, Arthrospira (Spirulina) platensis, is an important organism for industrial applications and as a food supply. Almost the complete genome of A. platensis NIES-39 was determined in this study. The genome structure of A. platensis is estimated to be a single, circular chromosome of 6.8 Mb, based on optical mapping. Annotation of this 6.7 Mb sequence yielded 6630 protein-coding genes as well as two sets of rRNA genes and 40 tRNA genes. Of the protein-coding genes, 78% are similar to those of other organisms; the remaining 22% are currently unknown. A total 612 kb of the genome comprise group II introns, insertion sequences and some repetitive elements. Group I introns are located in a protein-coding region. Abundant restriction-modification systems were determined. Unique features in the gene composition were noted, particularly in a large number of genes for adenylate cyclase and haemolysin-like Ca(2+)-binding proteins and in chemotaxis proteins. Filament-specific genes were highlighted by comparative genomic analysis.

Title : Aging-related alterations in the contractile responses to acetylcholine, muscarinic cholinoceptors and cholinesterase activities in jejunum and colon of the male Fischer 344 rats - Tezuka_2004_Exp.Gerontol_39_91

Abstract : In an attempt to examine whether the muscarinic receptor-activated intestinal function is altered by aging, we studied the changes in (1) contractile responses to acetylcholine (Ach), (2) muscarinic cholinoceptors and (3) cholinesterase (ChE) activities, in jejunum and colon of the young (2-3 months) and aged (24-28 months) Fischer 344 rats. In the physiological contraction experiments of jejunum and colon, Ach concentration-dependently increased the force of contraction, and the contractile responses to Ach were not affected by aging. In addition, the true- and pseudo-ChE activities were not significantly changed by aging. The Ach-induced contraction was competitively inhibited by muscarinic M3-selective antagonist hexahydro-sila-difenidolhydrochloride p-fluoroanalog (p-F-HHSiD), suggesting that the contractile responses in the rat jejunum and colon were mediated through M3-cholinoceptor. Age-related changes in muscarinic cholinoceptors of jejunum and colon were determined with the use of specific muscarinic radioligand [3H]-quinuclidinylbenzilate (QNB). The [3H]QNB saturation binding experiments revealed that the maximal binding (B(max)) was increased only in aged jejunum without changes in K(D) values. These results suggest that aging may not attenuate the Ach-induced intestinal contraction via muscarinic M3 receptor, although the expression of muscarinic cholinoceptor is differentially modulated in jejunum and colon.

Title : Effects of a novel cardiotonic agent (+-)-6-[3-(3,4-dimethoxybenzylamino)-2-hydroxypropoxy]-2(1H)-quinolino ne (OPC-18790) on contractile force, cyclic AMP level, and aequorin light transients in dog ventricular myocardium - Endoh_1994_J.Cardiovasc.Pharmacol_23_723

Abstract : We studied the effects of a novel cardiotonic agent OPC-18790 [(+-)-6-[3-(3,4-dimethoxybenzylamino)-2-hydroxypropoxy]-2(1H)- quinolinone] on isometric contractions, intracellular aequorin light transients, and cyclic AMP levels in isolated dog ventricular trabeculae. The positive inotropic effect (PIE) of OPC-18790 (1-30 microM) was consistently associated with an abbreviation of contractions and an increase in the amplitude of aequorin light transients. The maximum responses of Ca2+ transients and force to OPC-18790 were approximately 40% of the isoproterenol-induced maximum. Carbachol (3 microM) markedly attenuated the increases in force, light transients, and cyclic AMP accumulation induced by OPC-18790. These results indicate that OPC-18790 is a cardiotonic agent with moderate effectiveness, and that the PIE of OPC-18790 may be produced mainly by an increase in intracellular Ca2+ transients induced by cyclic AMP accumulation. For a given increase in amplitude of Ca2+ transients, OPC-18790 produced a more pronounced increase in force of contraction (FOC) than did isoproterenol, suggesting that OPC-18790 does not produce as great a decrease in Ca2+ sensitivity of contractile proteins as does isoproterenol. These observations indicate that among cardiotonic agents acting through cyclic AMP pathway, regulation of contractility produced by the selective cyclic AMP phosphodiesterase III (PDE-III) inhibitor OPC-18790 is qualitatively different from the regulation induced by isoproterenol that acts on cyclic AMP generation in intact myocardial cells.

Title : Cyclic AMP metabolism in intact rat ventricular cardiac myocytes: interaction of carbachol with isoproterenol and 3-isobutyl-1-methylxanthine - Katano_1993_Mol.Cell.Biochem_119_195
Author(s) : Katano Y , Endoh M

Abstract : Experiments were carried out to elucidate the characteristics of regulation of cyclic AMP levels in intact myocardial cells. For this purpose, the influence of isoproterenol, a nonselective cyclic nucleotide phosphodiesterase (PDE) inhibitor 3-isobutyl-1-methylxanthine (IBMX) and carbachol on cyclic AMP levels was investigated in isolated rat cardiac myocytes. The extent of cyclic AMP accumulation induced by isoproterenol was much less than that produced by IBMX: submaximal concentrations of isoproterenol and IBMX elevated the cyclic AMP level 2.4- and 4.8-fold of the control level, respectively. Both agents in combination increased the cyclic AMP level markedly 48-fold. Carbachol inhibited the cyclic AMP accumulation induced by isoproterenol, IBMX and their combination by 30%, 60% and 80% of the respective response. The extent of inhibition produced by carbachol of the cyclic AMP accumulation induced by IBMX + isoproterenol was smaller than that caused by propranolol, and carbachol produced only a marginal additional inhibitory action to that of propranolol, implying that carbachol does not affect the process of cyclic AMP degradation. The present findings indicate that in intact cardiac myocytes the rate of cyclic AMP degradation catalyzed by PDE may be a crucial process of cyclic AMP turnover. This view is supported by the observations that the inhibitory action of carbachol on the effect of isoproterenol was less than that on the effect of IBMX, and that the inhibitory action of carbachol was markedly enhanced by the simultaneous presence of IBMX.

Title : Modulation by aging of the coronary vascular response to endothelin-1 in the rat isolated perfused heart - Katano_1993_Naunyn.Schmiedebergs.Arch.Pharmacol_348_82

Abstract : Changes with age in the coronary vascular response to endothelin-1 were investigated in perfused hearts isolated from 2-, 6- and 24-month-old (mo) male Fisher-344 rats. Endothelin-1 injected as a single bolus (0.3, 3 and 30 nmol) into the coronary artery supply caused dose-dependent vasoconstriction in all three age groups. While there was no age-related change in the vasoconstriction induced by the lower doses (0.3 and 3 nmol), the higher dose (30 nmol) elicited a more pronounced vasoconstriction in 6- and 24-mo rats than that in 2-mo rats. NG-nitro-L-arginine (L-NNA), an inhibitor of nitric oxide formation, markedly enhanced the vasoconstriction induced by 30 nmol endothelin-1 in 2- and 6-mo rats but only slightly and non-significantly enhanced that vasoconstriction in 24-mo rats. Haemoglobin, which inhibits activation of guanylate cyclase by nitric oxide, enhanced the endothelin-1-induced vasoconstriction in 2-mo rats, but not in 6- and 24-mo rats. The acetylcholine-induced coronary vasodilation was more pronounced in 2- and 6-mo rats than in 24-mo rats and was attenuated by L-NNA in 2- and 6-mo rats. The coronary vasodilation induced by nitroprusside (0.1 mmol), a pharmacological precursor of nitric oxide, did not change with age. Endothelin-1 (30 nmol) markedly increased the release of 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha) in all three age groups. The prostaglandin synthesis inhibitor indomethacin enhanced the endothelin-1-induced vasoconstriction in 2- and 6-mo rats to a similar extent.(ABSTRACT TRUNCATED AT 250 WORDS)

Title : Influence of aging on the contractile response to endothelin of rat thoracic aorta - Ishihata_1991_Eur.J.Pharmacol_200_199
Author(s) : Ishihata A , Katano Y , Morinobu S , Endoh M
Ref : European Journal of Pharmacology , 200 :199 , 1991
Abstract : Age-related changes in the contractile response to endothelin-1 and ACh were assessed in thoracic aortas isolated from 2-, 6- and 24-month-old male Fischer 344 rats. In aortic strips with an intact endothelium, the maximal contractile response to endothelin-1 decreased with development to maturity. Removal of the endothelium did not affect the contractile response to endothelin-1. Endothelin-1 did not elicit a relaxant response in phenylephrine-precontracted strips. The ACh-induced relaxation decreased in senescent rats. These results indicate that the contractile response of aortic smooth muscle to endothelin-1 decreases with age, and that the endothelial vasorelaxant factors do not contribute to this age-induced modulation.
