Abstract : The rice species Oryza sativa is considered to be a model plant because of its small genome size, extensive genetic map, relative ease of transformation and synteny with other cereal crops. Here we report the essentially complete sequence of chromosome 1, the longest chromosome in the rice genome. We summarize characteristics of the chromosome structure and the biological insight gained from the sequence. The analysis of 43.3 megabases (Mb) of non-overlapping sequence reveals 6,756 protein coding genes, of which 3,161 show homology to proteins of Arabidopsis thaliana, another model plant. About 30% (2,073) of the genes have been functionally categorized. Rice chromosome 1 is (G + C)-rich, especially in its coding regions, and is characterized by several gene families that are dispersed or arranged in tandem repeats. Comparison with a draft sequence indicates the importance of a high-quality finished sequence.

Title : Inhibition of human plasma cholinesterase and erythrocyte acetylcholinesterase by nondepolarizing neuromuscular blocking agents - Kato_2000_J.Anesth_14_30

Abstract : PURPOSE: The kinetics of the inhibition of human plasma cholinesterase (ChE) and erythrocyte acetylcholinesterase (AChE) by alcuronium, atracurium, d-tubocurarine, pancuronium, pipecuronium, and vecuronium were studied in blood drawn from 35 surgical patients.
METHODS: The activities of plasma ChE and erythrocyte AChE were determined by the calorimetric method of Ellman et al., using acetylthiocholine as the substrate. Lineweaver-Burk plots and Dixon plots were used for the analysis of the kinetics of both enzymes.
RESULTS: The dissociation constants (K(m)) of plasma ChE and erythrocyte AChE were 5.00 x 10(-5) M and 5.28 x 10(-5) M, respectively, indicating that both enzymes have similar affinity to acetylthiocholine. Both Lineweaver-Burk plots and Dixon plots indicated that the six nondepolarizing neuromuscular blocking agents (NMBAs) at different concentrations induce linear mixed-type inhibition. The apparent inhibition constants (K(i)) of pancuronium (8.72 x 10(-8) M) and vecuronium (3.53 x 10(-7) M) for plasma ChE inhibition were lower than that of neostigmine (7.36 x 10(-7) M), whereas those of the six nondepolarizing NMBAs for erythrocyte AChE were markedly higher than that of neostigmine.
CONCLUSIONS: Both plasma ChE and erythrocyte AChE were inhibited by six nondepolarizing NMBAs, and the pattern of inhibition of both enzymes was of mixed type. The inhibitory potencies of pancuronium and vecuronium for plasma ChE were larger than that of neostigmine, whereas those of the six nondepolarizing NMBAs for erythrocyte AChE were markedly lower than that of neostigmine. The rank order of relative potency for plasma ChE was pancuronium > vecuronium > pipecuronium > alcuronium > d-tubocurarine > atracurium.

Title : Diversity of mRNA expression for muscarinic acetylcholine receptor subtypes and neuronal nicotinic acetylcholine receptor subunits in human mononuclear leukocytes and leukemic cell lines - Sato_1999_Neurosci.Lett_266_17

Abstract : Previously, we reported that various levels of acetylcholine (ACh), currently known as a neurotransmitter, are detectable in the blood of several mammals including humans and that most blood ACh originates from T-lymphocytes. To investigate whether ACh in the blood acts on lymphocytes and participates in the modulation of immune responses, we have analyzed the expression of mRNA for muscarinic (Ms) ACh receptor subtypes and nicotinic (Nc) ACh receptor subunits using reverse transcription-polymerase chain reaction (RT-PCR) methods. The cells tested were human peripheral mononuclear leukocytes (MNLs) from seven healthy donors and eight leukemic cell lines, as models of lymphocytes. We detected mRNA expression for various neuronal Nc receptor subunits and Ms receptor subtypes in all of the MNL samples and in all of the cell lines tested. However, the expression pattern of mRNA for neuronal Nc receptor subunits (alpha2-alpha7 and beta2-beta4) and Ms receptor subtypes (m1-m5) varied among the individuals and cell lines. No expression of mRNA for three muscle-type Nc receptor subunits (alpha1, beta1 and epsilon) was observed in the MNLs and cell lines. These results indicate that both neuronal-type Nc and Ms ACh receptors are present on the surface of lymphocytes.
