N Nagoda, A Fukuda, Y Nakashima and Yoshinori Matsuo : Molecular characterization and evolution of the repeating units of histone genes in Drosophila americana: coexistence of quartet and quintet units in a genome, Insect Molecular Biology, 14, 6, 713-717, 2005.
(要約)
Quintet and quartet repeating units of the histone genes in Drosophila americana were cloned and characterized. Nucleotide sequence analysis of the units showed that a 3175 bp unit contained the core histone genes but lacked the H1 gene ('quartet unit') while a 5025 bp unit contained all five histone genes ('quintet unit'). Comparative analysis suggested that these repeating units diverged before the separation of D. americana and D. virilis. Multiple forms of H1 genes, differing by 5.8% of amino acids, were found in D. americana. The genomic organization of the histone gene family in D. americana was found to be very similar to that of D. virilis.

(要約)
The repeating units of the histone gene cluster containing the H1, H2A, H2B and H4 genes were amplified by PCR from the Drosophila melanogaster species subgroup, i.e., D. yakuba, D. erecta, D. sechellia, D. mauritiana, D. teissieri and D. orena. The PCR products were cloned and their nucleotide sequences of about 4.6-4.8kbp were determined to elucidate the mechanism of molecular evolution of the histone gene family. The heterogeneity among the histone gene repeating units was 0.6% and 0.7% for D. yakuba and D. sechellia, respectively, indicating the same level of heterogeneity as in the H3 gene region of D. melanogaster. Divergence of the genes among species even in the most closely related ones was much greater than the heterogeneity among family members, indicating a concerted mode of evolution for the histone gene repeating units. Among the species in the D. melanogaster species subgroup, the histone gene regions as well as 3rd codon position of the coding region showed nearly the same GC contents. These results suggested that the previous conclusion on analysis of the H3 gene regions, the gene family evolution in a concerted fashion, holds true for the whole histone gene repeating unit.

Yoshinori Matsuo : Evolution of the GC content of the histone 3 gene in seven Drosophila species., Genes & Genetic Systems, 78, 4, 309-318, 2003.
(要約)
The molecular evolution of the histone multigene family was studied by cloning and determining the nucleotide sequences of the histone 3 genes in seven Drosophila species, D. takahashii, D. lutescens, D. ficusphila, D. persimilis, D.pseudoobscura, D. americana and D. immigrans. CT repeats, a TATA box and an AGTG motif in the 5' region, and a hairpin loop and purine-rich motifs (CAA(T/G)GAGA) in the 3' region were conserved even in distantly related species. In D. hydei and D.americana, the GC content at the third codon position in the protein coding region was relatively low (49% and 45%), while in D. takahashii and D. lutescens it was relatively high (64% and 65%). The non- significant correlation between the GC contents in the 3' region and at the third codon position as well as the evidence of less constraint in the 3' region suggested that mutational bias may not be the major mechanism responsible for the biased nucleotide change at the third codon position or for codon usage bias.

Kazunobu Tsunemoto and Yoshinori Matsuo : Molecular evolutionary analysis of a histone gene repeating unit from Drosophila simulans., Genes & Genetic Systems, 76, 6, 355-361, 2001.
(要約)
A repeating unit of the histone gene cluster from Drosophila simulans containing the H1, H2A, H2B and H4 genes (the H3 gene region has already been analyzed) was cloned and analyzed. A nucleotide sequence of about 4.6 kbp was determined to study the nucleotide divergence and molecular evolution of the histone gene cluster. Comparison of the structure and nucleotide sequence with those of Drosophila melanogaster showed that the four histone genes were located at identical positions and in the same directions. The proportion of different nucleotide sites was 6.3% in total. The amino acid sequence of H1 was divergent, with a 5.1% difference. However, no amino acid change has been observed for the other three histone proteins. Analysis of the GC contents and the base substitution patterns in the two lineages, D. melanogaster and D. simulans, with a common ancestor showed the following. 1) A strong negative correlation was found between the GC content and the nucleotide divergence in the whole repeating unit. 2) The mode of molecular evolution previously found for the H3 gene was also observed for the whole repeating unit of histone genes; the nucleotide substitutions were stationary in the 3' and spacer regions, and there was a directional change of the codon usage to the AT-rich codons. 3) No distinct difference in the mode or pattern of molecular evolution was detected for the histone gene repeating unit in the D. melanogaster and D. simulans lineages. These results suggest that selectional pressure for the coding regions of histones, which eliminate A and T, is less effective in the D. melanogaster and D. simulans lineages than in the other GC-rich species.

(要約)
Molecular evolution of the histone multigene family was studied by cloning and sequencing regions of the histone 3 gene in the Drosophila melanogaster species subgroup. Analysis of the nucleotide substitution pattern showed that in the coding region synonymous changes occurred more frequently to A or T in contrast to the GC-rich base composition, while in the 3' region the nucleotide substitutions were most likely in equilibrium. These results suggested that the base composition at the third codon position of the H3 gene, i.e., codon usage, has been changing to A or T in the Drosophila melanogaster species subgroup.

Yoshinori Matsuo : Evolutionary change of codon usage for the histone gene family in Drosophila melanogaster and Drosophila hydei., Molecular Phylogenetics and Evolution, 15, 2, 283-291, 2000.
(要約)
The nucleotide divergence in the protein-coding region for replication-dependent and replication-independent histone 3 and 4 genes of Drosophila melanogaster and Drosophila hydei occurred mostly at the synonymous site. Therefore, the pattern of codon usage was analyzed in the two species, considering the genomic codon bias, which is proposed for estimating the genomic composition pressure in the protein-coding regions. The results indicated that the codon usage in the histone gene family could be explained mostly by the genomic codon bias. However, biases for Ala and Arg were commonly observed for the histone 3 and histone 4 gene families, and biases for Ser, Leu, and Glu were observed in a gene-specific manner. This suggests that both genomic codon bias and gene- or codon-specific bias are responsible for the nucleotide differentiation in the protein-coding region of the histone genes.

(要約)
The relationship between the net charge of molecules and their mobility on electrophoresis was analyzed for Drosophila alpha-amylases. Most of the differences in electrophoretic mobility, 98.2%, can be explained by the charge state. Therefore five reference amino acid sites, which are informative residues for charge differences among amylase isozymes, were considered for the evolution of the isozymes in Drosophila melanogaster. The amylase isozymes in D. melanogaster can be classified into three groups, I (AMY1, AMY2, and AMY3-A), II (AMY3-B and AMY4), and III (AMY5, AMY6-A, and AMY6-B), based on the differences in the reference sites. The most primitive amylase in D. melanogaster was found to belong to Group I, most likely the AMY2 isozyme. Groups II and III could have been derived from Group I. These results were confirmed by the analysis of 38 amino acid sites with charge differences in Drosophila.

(要約)
The adaptation to glucose and starch foods in six species, D. melanogaster, D. virilis, D. saltans, D. funebris, D. levanonensis and D. americana, was studied by measuring productivity. D. melanogaster and D. virilis adapted more to the starch environment than to the glucose environment, while D. saltans adapted more to the glucose environment than to the starch environment. D. funebris, D. levanonensis, and D. americana did not distinctly adapt to either environment. In addition, the regulation of amylase in the six species was investigated by measuring the levels of amylase activity with glucose and starch food environments. The levels of amylase activity in D. levanonensis and D. saltans were substantially low, indicating that these species cannot utilize starch as a carbon source. The starch-adapted species, D. melanogaster and D. virilis, showed higher levels of amylase activity with the starch environment and higher inducibility. These results suggest that changing the regulation of amylase is important for the adaptation to a starch environment in Drosophila.

(要約)
The regulation of amylase activity in three Drosophila species, D. melanogaster, D. funebris and D. saltans, was analyzed by measuring the specific activity levels in four dietary environments, cornmeal, glucose, 5% starch, and 10% starch, at three developmental stages, i.e., the third-instar larval, pupal, and 2-day-old adult stages. The developmental profiles of amylase activity for the three Drosophila species showed that the level of activity was high at the larval and adult stages but substantially low at the pupal stage, suggesting that Drosophila does not utilize starch at the pupal stage. Divergence in the regulation of amylase was observed among the three Drosophila species on the following points. (1) The order of amylase specific activity was D. melanogaster > D. funebris > D. saltans. (2) The response pattern to the dietary environment varied among the species and changed during development. (3) The timing of the switch in the response pattern to the dietary environment during development was before pupation in D. funebris and D. saltans but after pupation in D. melanogaster. The significance of the divergence in the regulation of amylase activity for adaptation to a starch environment in Drosophila is discussed.

(要約)
To further investigate the association between Parkinson's disease (PD) and genetic polymorphism of the CYP2D6 gene, a mutant allele (CVP2D6J) frequently observed in the Japanese population and related to EM/PM polymorphism (phenotypically, individuals are either extensive metabolizers [EM] or poor metabolizers [PM] of debrisoquine) was investigated. The CYP2D6J gene with a nucleotide substitution from C to T at position 188 (the HphI site in exon 1), which reduces CYP2D6 enzyme activity, was analyzed by polymerase chain reaction (PCR) and by digestion with HphI. No significant relationship was observed between PD patients and controls for this mutation. This suggests that the EM/PM polymorphism of CYP2D6 contributes little to the pathogenesis of PD. To further study the molecular basis for the relationship between PD and CYP2D6, the heterogeneity of CYP2D6 was investigated by combined genotype analysis of the two mutant CYP2D6 genes (ie, CYP2D6J, the HphI site mutation in exon 1, and CYP2D6L, the HhaI site mutation in exon 6). Although some characteristic patterns of the combined genotypes were observed in both PD patients and controls, a strong association between the heterogeneity of the CYP2D6 gene and PD was not shown by combined genotype analysis.

Yoshinori Matsuo and Tsuneyuki Yamazaki : Genetic factors on the second and third chromosomes responsible for the variation of amylase activity and inducibility in Drosophila melanogaster, Genetical Research, 70, 2, 97-103, 1997.
(要約)
Using second- or third-chromosome substitution lines of Drosophila melanogaster, the genetic variation of inducibility and amylase specific activities in three media (starch, normal and glucose) were investigated. Genetic factors on both the second and third chromosomes were responsible for the variation in amylase specific activity and inducibility. In glucose medium, the genetic variance of amylase specific activity estimated for the second-chromosome substitution lines was larger than that for the third-chromosome substitution lines; however, for starch medium and inducibility, the variance was larger for the third-chromosome substitution lines. High correlations for the second-chromosome substitution lines and low correlations for the third-chromosome substitution lines were observed for amylase specific activities in different media. These results suggest that the genetic factor(s) responsible for inducibility or amylase activity variation in an induced medium such as starch should be on the third chromosome and those in the non-induced medium such as glucose should be on the second chromosome. The functional roles of the factors on the second and third chromosomes would be the repression and induction of amylase, respectively.

(要約)
1. To study the expression of a ferredoxin gene in extra-adrenocortical tissues, the amounts and structures of the ferredoxin gene transcripts in bovine liver and brain were studied and compared to those of that in adrenocortex. 2. The sizes and amounts of the ferredoxin mRNAs were analyzed by means of Northern blotting, RNA slot blotting and RT-PCR. 3. The nucleotide sequences were determined for 39 ferredoxin cDNA clones from bovine liver. 4. The results indicated that the sizes of the ferredoxin mRNAs in liver and brain were the same as that in adrenocortex, however, their amounts were approx 1/30th and less than the latter, respectively. 5. Although the multiple forms of ferredoxin cDNA, differing in the poly(A) addition sites, were also found in liver, a minor form of ferredoxin cDNA, produced through alternative promoter usage and splicing, could not be detected in liver. 6. The nucleotide sequences of all hepato-ferredoxin cDNA clones obtained were identical to that of a major type of adreno-ferredoxin. 7. These results showed that the expression level of the ferredoxin gene in different tissues was controlled by the amount of mRNA.

(要約)
A partial paired gene of Drosophila willistoni containing the paired box and extended homeo box was amplified by PCR and the nucleotide sequence of 1141 bp was determined. Comparison of the paired genes in D. willistoni and D. melanogaster showed that the proportions of identical nucleotide sites in the coding region and identical amino acid sites were 73.8 and 86.5%, respectively. The amino acid sites in the N-terminal region, the paired box, and the extended homeo box were 88.5, 95.3, and 98.6% identical in the two species. The rates of amino acid substitution for these regions were estimated to be 1.73 x 10(-9), 0.67 x 10(-9), and 0.19 x 10(-9)/site/year, respectively. In contrast, the connecting region between the two boxes has been highly diverged and evolved very rapidly, 18.3 x 10(-9)/site/year, suggesting almost no functional constraint in the connecting region.

(要約)
A polymorphic CYP2C19 gene was analyzed in 233 Japanese subjects, including 63 with Parkinson's disease, 92 with chronic liver diseases (35 chronic hepatitis, 19 liver cirrhosis, 16 hepatocellular carcinoma, 10 primary biliary cirrhosis and 12 autoimmune hepatitis), 14 with lung cancer (squamous cell carcinoma) and 64 healthy subjects to determine the genotype distributions of the CYP2C19 gene and to investigate its involvement in the diseases. Among Japanese healthy subjects 14.1% are predicted to be poor metabolizers (PM) of mephenytoin. The frequencies of the m1 and the m2 mutations of the CYP2C19 gene in the healthy subjects were 21.9% and 11.7%, respectively. Though the number of patients was small, patients with lung cancer (squamous cell carcinoma) are believed to have reduced enzyme activities of CYP2C19.

(要約)
The CYP2C18 gene was investigated in order to characterize its molecular basis in the CYP2C subfamily. A mutation of the CYP2C18 gene was identified at the 5'-flanking region of the gene, which could be detected by digestion with DdeI. The allele frequency of the mutant CYP2C18 gene was 21.4%. Genotypes of the polymorphic DdeI site of the CYP2C18 gene were found to be completely consistent with that of the polymorphic CYP2C19 gene (the m1 mutant). The CYP2C18 and CYP2C19 genes were suggested to be linked and located close together on the chromosome. Clones containing the 5'-flanking region of a member of the CYP2C subfamily were obtained from the PCR products from human genomic DNA. The nucleotide sequence of the clone proved to be 90.5% identical to the corresponding region of the CYP2C18 gene. This is very likely to be a novel member of the CYP2C subfamily.

(要約)
We examined the genotypes of the aldehyde dehydrogenase (ALDH)-2, alcohol dehydrogenase (ADH)-2, ADH3, and P-4502E1 loci of 53 alcoholics and 97 nonalcoholics. All of the subjects fulfilled the DSM-III-R criteria for alcohol dependence. The control group consisted of 97 subjects who were either hospital staff or students. We also compared the frequencies of homozygous ALDH2*1/1 and heterozygous ALDH2*1/2 genotypes in alcoholics. Our study revealed differences in the allelic frequencies of the ALDH2, ADH2, and ADH3 loci between alcoholics and nonalcoholics. For alcoholics with both homozygous ALDH2*1/1 and heterozygous ALDH2*1/2 genotypes, it was found that ADH2 and ADH3 played important rates. Alcoholics with the heterozygous ALDH2*1/2 genotype showed a significantly higher frequency of ADH2*1/1 than ones with the homozygous ALDH2*1/1 genotype. We assume ADH2*1 plays an important role in the development of alcoholism in alcoholics with the heterozygous ALDH2*1/2 genotype.

(要約)
The genotypes of the CYP2E1 and ALDH2 loci of alcoholic (alcohol dependence) and nonalcoholic (healthy) Japanese were investigated to examine the relationship between the polymorphism of CYP2E1 (C1/C2) and ALDH2 (ALDH2*1/ALDH2*2), and the susceptibility to alcoholism. There was no significant difference in C2 gene frequency between alcoholics (0.19) and nonalcoholics (controls) (0.20), whereas there was a significant difference in ALDH2 allele frequency, suggesting that, in Japanese, the C2 genotype of CYP2E1 may have nothing to do with the risk of developing alcohol dependence. However, the ALDH2*1 allele may influence drinking behavior and the development of alcohol dependence. Furthermore, racial interethnic differences in the frequency of the mutated allele of the CYP2E1 gene (C2) were found, like the ALDH2 gene. Japanese healthy controls showed a significantly higher frequency of the C2 allele than did Swedish healthy controls (0.05; reported by Persson et al., FEBS Lett. 319:207-211, 1993).

The genotypes of the ALDH2 and CYP2E1 loci of Japanese alcoholic patients were determined to investigate the susceptibility to alcoholic liver injury. In alcoholics with a liver-function disorder, a significant association was observed between the genotypes of the CYP2E1 loci and the serum level of a liver-derived enzyme, LAP. However, there was no significant association between the ALDH2 genotypes and liver dysfunction.

(要約)
Four drug-metabolizing activities in Wistar rat and Mongolian gerbil liver microsomes were investigated to clarify the biochemical basis of convulsions. No significant associations were observed between the susceptibility to the tonic-clonic seizures in Mongolian gerbils and the drug-metabolizing enzymatic activities of p-nitroanisole O-demethylase, aminopyrine demethylase and benzo[a]pyrene-3-monooxygenase. However, a significant association was observed with the debrisoquine 4-monooxygenase (cytochrome P-450db1-linked monooxygenase system) activity, which is known to metabolize exogenous and endogenous parkinsonism-inducing neurotoxins such as MPTP and TIQ, and to activate carcinogens during the detoxication of xenobiotics. The mean activity of debrisoquine 4-monooxygenase in the seizure-sensitive group (male, 380; female, 350 pmol/h/mg protein) remained significantly higher (about 4-5 times) than that in the seizure-resistant group (male, 90; female, 80 pmol/h/mg protein). More Mongolian gerbils were extensive metabolizers of debrisoquine in the seizure-sensitive group than in the seizure-resistant group. These results suggest a possibility that the cytochrome P-450db1-linked monooxygenase system may activate the potential neurotoxins which are associated with tonic-clonic seizures in the Mongolian gerbil.

(要約)
1. To characterize an enzyme which metabolizes retinal in liver microsomes, several properties of the enzymatic reaction from retinal to retinoic acid were investigated using rabbit liver microsomes. 2. The maximum pH of the reaction in the liver microsomes was 7.6. 3. The Km and Vmax values for all-trans, 9-cis and 13-cis-retinals were determined. 4. The reaction proceeded in the presence of NADPH and molecular oxygen. 5. The incorporation of one atom of molecular oxygen into retinal was confirmed by using oxygen-18, showing that the reaction comprised monooxygenation, not dehydrogenation. 6. The monooxygenase activity was inhibited by carbon monoxide, phenylisocyanide and anti-NADPH-cytochrome P-450 reductase IgG, but not by anti-cytochrome b5 IgG. 7. The enzymatic activity inhibited by carbon monoxide was photoreversibly restored by light of a wavelength of around 450 nm. 8. The retinal-induced spectra of liver microsomes with three isomeric retinals were type I spectra. 9. The microsomal monooxygenase activity induced by phenobarbital or ethanol were more effective than that by 3-methylcholanthrene, clotrimazole or beta-naphthoflavone. 10. These results showed that the monooxygenase reaction from retinal to retinoic acid in liver microsomes is catalyzed by a cytochrome P-450-linked monooxygenase system.

(要約)
The effects of interleukin 2 (IL-2), a pivotal cytokine for generating an effective immune response, on rat liver microsomal cytochrome P450-linked monooxygenase systems were investigated by measuring the contents of cytochromes b5 and P450, and the activities of various xenobiotic-metabolizing enzymes [debrisoquine and bufuralol monooxygenases (CYP2D), 7-ethoxycoumarin O-deethylase, benzphetamine N-demethylase, aniline hydroxylase and p-nitroanisole N-demethylase]. The enzymatic activities except for p-nitroanisole N-demethylase and aniline hydroxylase were increased approximately to 1.3-fold of those of untreated liver microsomes following intraperitoneal injection of IL-2 (15 U/rat). However, the amount of immunoreactive b5 protein, and the activities of aniline hydroxylase and p-nitroanisole N-demethylase were not changed by injection of IL-2. To elucidate further the mechanism of the induction of CYP2D by IL-2, quantitative analyses of immunoreactive CYP2D protein and its mRNA were conducted by western blot and slot blot hybridization analyses. The results indicated that IL-2 induced an increase in the amounts of immunoreactive CYP2D protein and its mRNA. These enzymatic activities were thus up-regulated at the mRNA level.

(要約)
The largest group of transposable elements in Drosophila melanogaster, copia-like elements, share some important structural features with and are intimately related in evolution to vertebrate retroviruses. To further clarify the relationship between retroviruses and copia-like transposable elements, we set out to determine the complete nucleotide sequence of the genome of 17.6, which has long terminal repeats homologous in nucleotide sequence to those of avian leukaemia-sarcoma virus. We report here that 17.6 contains three long open reading frames comparable with gag, pol and env genes in retrovirus. At the level of amino acid sequence, the longest open reading frame of 17.6 includes a coding sequence similar to that for reverse transcriptase, suggesting a role for this enzyme in the life cycle of some Drosophila copia-like elements, analogous to the situation in retrovirus.
