Abstract : AIMS: Identifying patients with vulnerable plaque who have poor prognosis among those with coronary artery disease (CAD) is crucial to deciding future therapeutic interventions. We previously reported that male CAD patients with low anti-apolipoprotein B-100 autoantibody (anti-apoB-100 Ab) levels were at an increased risk of developing unstable plaque lesions. This study focused on the autoantibodies against lipoprotein lipase (LPL), a key enzyme in triglyceride metabolism, which is another risk factor for atherosclerosis, and investigated their association with plaque characteristics. METHODS: We measured serum anti-LPL Ab levels using a homemade enzyme-linked immunosorbent assay in 80 male CAD patients. Coronary plaque properties were evaluated using iMAP(a)-intravascular ultrasound. RESULTS: Serum anti-LPL Ab levels were not correlated with plaque burden but were significantly negatively and positively correlated with fibrotic and necrotic plaques, respectively. High-risk patients with low anti-apoB-100 Ab levels were divided into groups according to their anti-LPL Ab levels. The group with high anti-LPL Ab levels exhibited more necrotic plaques and fewer fibrotic plaques as well as higher remnant-like lipoprotein particle levels than the group with low anti-LPL Ab levels. CONCLUSIONS: Serum anti-LPL Ab levels can serve as a marker of plaque instability in CAD patients and can help identify higher-risk cases when combined with anti-apoB-100 Ab levels.

Abstract : The transcript level of alcohol acyltransferase 1 (AAT1) may be the main factor influencing the variations in volatile esters that characterizing the fruity/exotic aroma of pepper fruit. Volatile esters are key components for characterizing the fruity/exotic aroma of pepper (Capsicum spp.) fruit. In general, the volatile ester content in the fruit is the consequence of a delicate balance between their synthesis by alcohol acyltransferases (AATs) and degradation by carboxylesterases (CXEs). However, the precise role of these families of enzymes with regard to volatile ester content remains unexplored in Capsicum. In this study, we found that the volatile ester content was relatively low in C. annuum and much higher in C. chinense, particularly in pungent varieties. Additionally, fruits collected from multiple non-pungent C. chinense varieties, which harbor loss-of-function mutations in capsaicinoid biosynthetic genes, acyltransferase (Pun1), putative aminotransferase (pAMT), or putative ketoacyl-ACP reductase (CaKR1) were analyzed. The volatile ester contents of non-pungent C. chinense varieties (pamt/pamt) were equivalent to those of pungent varieties, but their levels were significantly lower in non-pungent NMCA30036 (pun1(2)/pun1(2)) and C. chinense (Cakr1/Cakr1) varieties. Multiple AAT-like sequences were identified from the pepper genome sequences, whereas only one CXE-like sequence was identified. Among these, AAT1, AAT2, and CXE1 were isolated from fruits of C. chinense and C. annuum. Gene expression analysis revealed that the AAT1 transcript level is a potential determinant of fruit volatile ester variations in Capsicum. Furthermore, enzymatic assays demonstrated that AAT1 is responsible for the biosynthesis of volatile esters in pepper fruit. Identification of a key gene for aroma biosynthesis in pepper fruit will provide a theoretical basis for the development of molecular tools for flavor improvement.

Title : A pulse-chasable reporter processing assay for mammalian autophagic flux with HaloTag - Yim_2022_Elife_11_
Author(s) : Yim WW , Yamamoto H , Mizushima N
Ref : Elife , 11 : , 2022
Abstract : Monitoring autophagic flux is necessary for most autophagy studies. The autophagic flux assays currently available for mammalian cells are generally complicated and do not yield highly quantitative results. Yeast autophagic flux is routinely monitored with the green fluorescence protein (GFP)-based processing assay, whereby the amount of GFP proteolytically released from GFP-containing reporters (e.g. GFP-Atg8), detected by immunoblotting, reflects autophagic flux. However, this simple and effective assay is typically inapplicable to mammalian cells because GFP is efficiently degraded in lysosomes while the more proteolytically resistant red fluorescent protein (RFP) accumulates in lysosomes under basal conditions. Here, we report a HaloTag (Halo)-based reporter processing assay to monitor mammalian autophagic flux. We found that Halo is sensitive to lysosomal proteolysis but becomes resistant upon ligand binding. When delivered into lysosomes by autophagy, pulse-labeled Halo-based reporters (e.g. Halo-LC3 and Halo-GFP) are proteolytically processed to generate Halo(ligand) when delivered into lysosomes by autophagy. Hence, the amount of free Halo(ligand) detected by immunoblotting or in-gel fluorescence imaging reflects autophagic flux. We demonstrate the applications of this assay by monitoring the autophagy pathways, macroautophagy, selective autophagy, and even bulk nonselective autophagy. With the Halo-based processing assay, mammalian autophagic flux and lysosome-mediated degradation can be monitored easily and precisely.

Abstract : INTRODUCTION: Overexpression of lipoprotein lipase (LPL) protects against high-fat-diet (HFD)-induced obesity and insulin resistance in transgenic rabbits; however, the molecular mechanisms remain unclear. Skeletal muscle is a major organ responsible for insulin-stimulated glucose uptake and energy expenditure. OBJECTIVES: The main purpose of the current study was to examine the effects of the overexpression of LPL on the skeletal muscle metabolomic profiles to test our hypothesis that the mitochondrial oxidative metabolism would be activated in the skeletal muscle of LPL transgenic rabbits and that the higher mitochondrial oxidative metabolism activity would confer better phenotypic metabolic outcomes. METHODS: Under a HFD, insulin resistance index was measured using the intravenous glucose tolerance test, and total energy expenditure (TEE) was measured by doubly-labeled water in control and LPL transgenic rabbits (n = 12, each group). Serum lipids, such as triglycerides and free fatty acid, were also measured. The skeletal muscle metabolite profile was analyzed using capillary electrophoresis time-of flight mass spectrometry in the two groups (n = 9, each group). A metabolite set enrichment analysis (MSEA) with muscle metabolites and a false discovery rate q < 0.2 was performed to identify significantly different metabolic pathways between the 2 groups. RESULTS: The triglycerides and free fatty acid levels and insulin resistance index were lower, whereas the TEE was higher in the LPL transgenic rabbits than in the control rabbits. Among 165 metabolites detected, the levels of 37 muscle metabolites were significantly different between the 2 groups after false discovery rate correction (q < 0.2). The MSEA revealed that the TCA cycle and proteinogenic amino acid metabolism pathways were significantly different between the 2 groups (P < 0.05). In the MSEA, all four selected metabolites for the TCA cycle (2-oxoglutaric acid, citric acid, malic acid, fumaric acid), as well as eight selected metabolites for proteinogenic amino acid metabolism (asparagine, proline, methionine, phenylalanine, histidine, arginine, leucine, isoleucine) were consistently increased in the transgenic rabbits compared with control rabbits, suggesting that these two metabolic pathways were activated in the transgenic rabbits. Some of the selected metabolites, such as citric acid and methionine, were significantly associated with serum lipids and insulin resistance (P < 0.05). CONCLUSION: The current results suggest that the overexpression of LPL may lead to increased activities of TCA cycle and proteinogenic amino acid metabolism pathways in the skeletal muscle, and these enhancements may play an important role in the biological mechanisms underlying the anti-obesity/anti-diabetes features of LPL overexpression.

Abstract : Introduction: Alpha/beta-hydrolase domain 6 (ABHD6) is an enzyme that hydrolyzes 2-arachidonoylglycerol, a high-efficiency endogenous cannabinoid. Although the endocannabinoid system has been suggested to be involved in regulation of bladder function, the roles of ABHD6 in the control of micturition remain unknown. To elucidate the physiological and pathological roles of ABHD6 in vivo, we examined phenotypes of ABHD6 knockout rats (Abhd6(-/-)) generated by clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated proteins system. Materials and Methods: Age-matched knockout and wild-type (WT) rats of both sexes were used. Results: Expression of ABHD6, assessed by quantitative real-time polymerase chain reaction and Western blot analysis, was clearly diminished in Abhd6(-/-) rats compared with WT rats. Mutant rats had a normal appearance, and the body weight and food consumption were similar to those of WT rats. The interval between bladder contractions assessed by continuous cystometry was significantly shorter in ABHD6 knockout rats than in WT rats when the bladder was stimulated with acetic acid. Mechanical paw withdrawal thresholds measured by von Frey testing were significantly lowered in the knockout rats than in WT rats. The plasma levels of prostaglandin E(2) (PGE(2)) and the stable metabolite of PGE(2) in Abhd6(-/-) rats were twice as high as that in WT rats. Conclusions: Deletion of the ABHD6 gene in rats causes more frequent urination in the stimulated bladder and hyperalgesia to non-noxious mechanical stimuli along with increased plasma PGE(2).

Abstract : Objectives: Butyrylcholinesterase (BChE) is an alpha-glycoprotein synthesized in the liver. Its serum levels are reportedly correlated with disease activity in patients with cancer. The aim of this study was to estimate the potential prognostic significance of preoperative serum BChE levels in patients with upper urinary tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU). Methods: Of the 220 patients with UTUC who underwent RNU between 1995 and 2016 at Hirosaki University Hospital, 149 patients with available laboratory data were included for analysis. Covariates included age, sex, preoperative laboratory data, clinical T and N grades, tumor grade, tumor location and preoperative chemotherapy. Univariate and multivariate analyses were performed to identify clinical factors associated with overall survival (OS) and disease-free survival (DFS). Univariate analysis was performed using the Kaplan-Meier and log-rank methods, and the multivariate analysis was performed using a Cox proportional hazard model. Results: The median BChE level was 276 U/l and the optimal cut-off point for the serum BChE level was determined to be 218 IU/ml. The 5-year OS and DFS rates were 81.0% and 73.7%, respectively. The 5-year OS and DFS rates were significantly greater in the BChE >/= 218 than <218 U/l groups (86.6% vs. 53.7%, P < 0.001 and 76.4% vs. 58.3%, P = 0.049, respectively). In multivariate analysis, BChE levels were most significantly associated with OS, whereas BChE level and tumor grade were significantly associated with DFS. Conclusions: This study validated preoperative serum BChE levels as an independent prognostic factor for UTUC after RNU.

Abstract : BACKGROUND: Butyrylcholinesterase (BChE) is an alpha-glycoprotein found in the nervous system and liver. Its serum level is reduced in many clinical conditions, such as liver damage, inflammation, injury, infection, malnutrition, and malignant disease. In this study, we analyzed the potential prognostic significance of preoperative BChE levels in patients with prostate cancer (PCa) undergoing radical prostatectomy (RP).
METHODS: We retrospectively evaluated 535 patients with PCa who underwent RP from 1996-2014 at a single institution. Serum BChE was routinely measured in all patients before operation. Covariates included age, preoperative laboratory data [prostate-specific antigen (PSA), hemoglobin, total protein, albumin, BChE, lactate dehydrogenase, C-reactive protein], clinical T, biopsy Gleason score, D'Amico risk classification, and RP with/without neoadjuvant therapy. Univariate and multivariate analyses were performed to identify clinical factors associated with biochemical recurrence-free survival (BRFS). Univariate analyses were performed using the Kaplan-Meier and log-rank methods, and multivariate analysis was performed using a Cox proportional hazard model.
RESULTS: The median BChE level was 255 U/L (normal range 168-470 U/L). The median age of the enrolled patients was 68 years, and the median PSA level at diagnosis of PCa was 8.39 ng/mL. The median follow-up period was 65 months. The 5-year BRFS rate was 72.9 %. The 5-year BRFS rates in the BChE >/=168 and <= 167 U/L groups were 77.7 and 55.0 %, respectively (P < 0.001). In univariate analysis, BChE, cT, biopsy Gleason score, and D'Amico risk classification were significantly associated with BRFS. Multivariate analysis revealed that BChE was significantly associated with BRFS.
CONCLUSIONS: This study validated preoperative serum BChE levels as an independent prognostic factor for PCa after RP.

Title : Estimation of the Intestinal Absorption and Metabolism Behaviors of 2- and 3-Monochloropropanediol Esters - Kaze_2016_Lipids_51_913

Abstract : The regioisomers of the di- and mono-oleate of monochloropropanediol (MCPD) have been synthesized and subsequently hydrolyzed with pancreatic lipase and pancreatin to estimate the intestinal digestion and absorption of these compounds after their intake. The hydrolysates were analyzed by HPLC using a corona charged aerosol detection system, which allowed for the separation and detection of the different regioisomers of the MCPD esters. The hydrolysates were also analyzed by GC-MS to monitor the free MCPD. The results indicated that the two acyl groups of 2-MCPD-1,3-dioleate were smoothly hydrolyzed by pancreatic lipase and pancreatin to give free 2-MCPD. In contrast, the hydrolysis of 3-MCPD-1,2-dioleate proceeded predominantly at the primary position to produce 3-MCPD-2-oleate. 2-MCPD-1-oleate and 3-MCPD-1-oleate were further hydrolyzed to free 2- and 3-MCPD by pancreatic lipase and pancreatin, although the hydrolysis of 3-MCPD-2-oleate was 80 % slower than that of 3-MCPD-1-oleate. The intestinal absorption characteristics of these compounds were evaluated in vitro using a Caco-2 cell monolayer. The results revealed that the MCPD monooleates, but not the MCPD dioleates, were hydrolyzed to produce the free MCPD in the presence of the Caco-2 cells. The resulting free MCPD permeated the Caco-2 monolayer most likely via a diffusion mechanism because their permeation profiles were independent of the dose. Similar permeation profiles were obtained for 2- and 3-MCPDs.

Abstract : Aquaporin-7 (AQP7) is expressed in adipose tissue, permeated by water and glycerol, and is involved in lipid metabolism. AQP7-null mice develop obesity, insulin resistance, and adipocyte hypertrophy. Here, we show that AQP7 is expressed in adipocyte plasma membranes, and is re-localized to intracellular membranes in response to catecholamine in mouse white adipose tissue. We found that internalization of AQP7 was induced by PKA activation and comparative gene identification 58 (CGI-58). This relocation was confirmed by functional studies in 3T3-L1 adipocytes. Collectively, these results suggest that AQP7 makes several contributions to adipocyte metabolism, in both cortical and intracellular membranes.

Abstract : The prognostic factors for the overall survival (OS) of clear cell renal cell carcinoma (ccRCC) patients treated with nephrectomy are not well defined. In the present study, we investigated the prognostic significance of preoperative butyrylcholinesterase (BChE) levels in 400 ccRCC patients undergoing radical or partial nephrectomy from 1992 to 2013 at our institution. Univariate and multivariate analyses were performed to determine the clinical factors associated with OS. Among the enrolled patients, 302 were diagnosed with organ-confined disease only (T1-2N0M0), 16 with lymph node metastases, and 56 with distant metastases. The median preoperative BChE level was 250 U/L (normal range, 168-470 U/L), and median follow-up period was 36 months. The 3-year OS rate in patients with preoperative BChE levels of >/=100 U/L was significantly higher than in those with levels of <100 U/L (89.3% versus 77.7%, P = 0.004). On univariate analysis, performance status; anemia; hypoalbuminemia; preoperative levels of BChE, corrected calcium, and C-reactive protein; and distant metastasis status were significantly associated with OS. Multivariate analysis revealed that preoperative BChE levels and distant metastasis status were significantly associated with OS. Our findings suggest a possible role of preoperative BChE levels as an independent predictor of OS after nephrectomy in ccRCC patients.

Abstract : OBJECTIVES: Butyrylcholinesterase (BChE) is an alpha-glycoprotein found in the nervous system and liver. Its serum level is reduced in many clinical conditions, such as liver damage, inflammation, injury, infection, malnutrition, and malignant disease. In this study, we analyzed the potential prognostic significance of preoperative BChE levels in patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy (RC). METHODS AND MATERIALS: We retrospectively evaluated 327 patients with MIBC who underwent RC from 1996 to 2013 at a single institution. Serum BChE level was routinely measured before operation in all patients. Covariates included age, gender, preoperative laboratory data (anemia, BChE, lactate dehydrogenase, and C-reactive protein), clinical T (cT) and N stage (cN), tumor grade, and RC with/without neoadjuvant chemotherapy. Univariate and multivariate analyses were performed to identify clinical factors associated with overall survival (OS) and disease-free survival (DFS). Univariate analyses were performed using the Kaplan-Meier and log-rank methods, and the multivariate analysis was performed using a Cox proportional hazard model.
RESULTS: The median BChE level was 187U/l (normal range: 168-470U/l). The median age of the enrolled patients was 69 years, and the median follow-up period was 51 months. The 5-year OS and DFS rates were 69.6% and 69.3%, respectively. The 5-year OS rates were 90.1% and 51.3% in the BChE>/=168 and<168U/l groups, respectively (P<0.001). The 5-year DFS rates were 83.5% and 55.4% in the BChE>/=168 and</=167U/l groups, respectively (P<0.001). In the univariate analysis, BChE, cT, cN, and RC with/without neoadjuvant chemotherapy were significantly associated with both OS and DFS. Multivariate analysis revealed that BChE was the factor most significantly associated with OS, and BChE, cT, and cN were significantly associated with DFS.
CONCLUSIONS: This study validated preoperative serum BChE levels as an independent prognostic factor for MIBC after RC.

Title : Effect of distigmine combined with propiverine on bladder activity in rats with spinal cord injury - Sugaya_2012_Int.J.Urol_19_480

Abstract : It is not uncommon for patients with spinal cord injury to have both detrusor overactivity during the storage phase and detrusor underactivity during the voiding phase. However, there has been no information about the efficacy of combined treatment with cholinesterase inhibitors and anti-muscarinic agents for this condition. Therefore, the effect of co-administration of distigmine bromide (a cholinesterase inhibitor) and propiverine hydrochloride (an anti-muscarinic agent) on bladder activity was examined in rats with spinal cord injury. Rats were anesthetized with isoflurane and the lower thoracic spinal cord was transected. The bladder was emptied by abdominal compression twice a day for 14 days after surgery. A total of 4 weeks after surgery, the animals were anesthetized with urethane, and the effect of intravenous injection of distigmine (0.01-1 mg/kg) followed by propiverine (1 mg/kg) on continuous cystometry parameters was examined. After injection of distigmine (0.1 and 1 mg/kg), the maximum bladder contraction pressure was significantly increased, and the duration of bladder contraction and the interval between bladder contractions were significantly prolonged. The baseline bladder pressure was not changed by injection of distigmine. After the addition of propiverine, the interval between bladder contractions was significantly further prolonged without any change of the maximum contraction pressure, baseline pressure or duration of bladder contraction. The residual volume after voiding bladder contraction was less than 0.1 mL in all animals. In conclusion, co-administration of distigmine with propiverine might improve both bladder underactivity during the voiding phase and bladder overactivity during the storage phase.

Title : NDRG4 protein-deficient mice exhibit spatial learning deficits and vulnerabilities to cerebral ischemia - Yamamoto_2011_J.Biol.Chem_286_26158

Abstract : The N-myc downstream-regulated gene (NDRG) family consists of four related proteins, NDRG1-NDRG4, in mammals. We previously generated NDRG1-deficient mice that were unable to maintain myelin sheaths in peripheral nerves. This condition was consistent with human hereditary motor and sensory neuropathy, Charcot-Marie-Tooth disease type 4D, caused by a nonsense mutation of NDRG1. In contrast, the effects of genetic defects of the other NDRG members remain unknown. In this study, we focused on NDRG4, which is specifically expressed in the brain and heart. In situ mRNA hybridization on the brain revealed that NDRG4 was expressed in neurons of various areas. We generated NDRG4-deficient mice that were born normally with the expected Mendelian frequency. Immunochemical analysis demonstrated that the cortex of the NDRG4-deficient mice contained decreased levels of brain-derived neurotrophic factor (BDNF) and normal levels of glial cell line-derived neurotrophic factor, NGF, neurotrophin-3, and TGF-beta1. Consistent with BDNF reduction, NDRG4-deficient mice had impaired spatial learning and memory but normal motor function in the Morris water maze test. When temporary focal ischemia of the brain was induced, the sizes of the infarct lesions were larger, and the neurological deficits were more severe in NDRG4-deficient mice compared with the control mice. These findings indicate that NDRG4 contributes to the maintenance of intracerebral BDNF levels within the normal range, which is necessary for the preservation of spatial learning and the resistance to neuronal cell death caused by ischemic stress.

Title : Effect of cortisol on cell proliferation and the expression of lipoprotein lipase and vascular endothelial growth factor in a human osteosarcoma cell line - Sakayama_2008_Cancer.Chemother.Pharmacol_61_471
Author(s) : Sakayama K , Mashima N , Kidani T , Miyazaki T , Yamamoto H , Masuno H

Abstract : PURPOSE: The aim of this study is to investigate whether cortisol inhibited cell proliferation and the expressions of lipoprotein lipase (LPL), a key enzyme involved in the energy metabolism in tumor cells, and vascular endothelial growth factor (VEGF), a potent angiogenic factor in the tumor, in cultures of OST cells, a human osteosarcoma cell line. METHODS: OST cells were treated for 48 h with or without cortisol. To examine the effect of cortisol on cell proliferation, the expression of proliferating cell nuclear antigen (PCNA) was examined by Western blotting, and the amount of (3)H-thymidine incorporated into DNA during the last 30 min of the 48-h treatment period was measured. To examine the effect of cortisol on the expression of LPL, the activity and mass of LPL were measured in the extract of acetone/ether powder of cells, and the amount of (35)S-methionine incorporated into LPL during the last 2 h of the 48-h treatment period was measured by immunoprecipitation. The expression of VEGF was examined by immunohistochemistry and Western blotting. RESULTS: The amount of (3)H-thymidine incorporated into DNA and the level of PCNA were lower in the cortisol-treated cultures than in the untreated cultures, thus indicating that cortisol inhibited the proliferation of OST cells. The synthetic rate and activity of LPL were lower in the cortisol-treated cultures than in the untreated cultures but no difference in the specific activity of LPL between the two cultures was observed, thus indicating that cortisol inhibited LPL synthesis, thereby resulting in a decreased LPL activity. The expression of VEGF was lower in the cortisol-treated cultures than in the untreated cultures. CONCLUSION: Cortisol not only has the ability to inhibit cell proliferation but also the ability to inhibit the expressions of LPL and VEGF in cultures of OST cells.

Abstract : The purpose of this study was to explore the triacylglycerol (TG) deposition and lipoprotein lipase (LPL) activity in the adipose tissue of patients with muculoskeletal sarcoma. Subcutaneous adipose tissue was obtained from the thighs of 19 patients with musculoskeletal sarcomas (sarcoma group) and 20 patients with osteoarthritis of the hip joint (control group) at surgery. The adipose tissue was homogenized and aliquots of the homogenate were used to measure the TG content and to prepare an acetone/ether powder to measure the LPL activity. The TG content was higher, but not significantly, in the sarcoma group than in the control group. The LPL activity of the sarcoma group was significantly higher than that of the control group. The TG content of the sarcoma group correlated positively with the LPL activity. [35S]Methionine incorporation investigation showed that the rate of LPL synthesis was significantly higher in the sarcoma group than in the control group. These results indicated that LPL was up-regulated at the transcriptional/translational level, thus resulting in an increased TG deposition in the adipose tissue of patients with muculoskeletal sarcoma.

Title : Application of commercially available fenitrothion-ELISA kit for soil residue analysis - Conde_2008_J.Pestic.Sci_33_51
Author(s) : Conde S , Suyama K , Itoh K , Yamamoto H
Ref : Journal of Pesticide Science , 33 :51 , 2008
Abstract : A commercially available fenitrothion-ELISA kit, designed for residue analysis of crop samples, was applied in a method development study using 10 different soils spiked with the target pesticide. Recoveries determined by gas chromatography (GC) were compared to those in ELISA analysis. Recoveries in ELISA were biased high in six soil samples which had low pH and high sand content. The range of recoveries in 10 soils was from 87 to 163% while, in contrast, GC recovery was 72-86%. Soil matrix, such as high-molecular-weight organics and divalent cations, influenced the ELISA reaction to cause an overestimation of recovery.

Title : Simultaneous display of bacterial and fungal lipases on the cell surface of Bacillus subtilis - Kobayashi_2002_J.Biosci.Bioeng_93_15
Author(s) : Kobayashi G , Fujii K , Serizawa M , Yamamoto H , Sekiguchi J
Ref : J Biosci Bioeng , 93 :15 , 2002
Abstract : A small cell wall-binding domain (CWB(c)) of the Bacillus subtilis peptidoglycan hydrolase CwlC fused to B. subtilis lipase B was able to be localized on the cell wall of B. subtilis. With the aim of developing an efficient lipid-hydrolyzing bacterium with two different lipases on the cell surface, plasmids possessing genes for LipB-CWB(c) and CWB(b)-CutL (the cell wall-binding domain of CwlB fused to the Aspergillus oryzae lipolytic enzyme CutL) were constructed. B. subtilis harboring these plasmids accumulated considerable amounts of both lipases on the cell surface.

Abstract : cutL cDNA encoding an extracellular lipase, L1, from Aspergillus oryzae was fused to the cell wall-binding domain (CWB) region of a plasmid, pHCB3R. SDS-polyacrylamide gel electrophoresis (PAGE) and zymography of proteins extracted from the cell surface of Bacillus subtilis 168 harboring a fused lipase plasmid (pHCB3RCL) revealed that the fused gene product, CWB-CutL, was localized in the B. subtilis cell wall and retained lipase activity. B. subtilis WASD (wprA sigD), recently used for the accumulation of CWB-LipB (the CWB protein fused with B. subtilis lipase B), was also a suitable host for the accumulation of CWB-CutL, the amount being 10% of the total proteins extracted from the cell surface.

Title : Accumulation of an artificial cell wall-binding lipase by Bacillus subtilis wprA and\/or sigD mutants - Kobayashi_2000_FEMS.Microbiol.Lett_188_165
Author(s) : Kobayashi G , Toida J , Akamatsu T , Yamamoto H , Shida T , Sekiguchi J
Ref : FEMS Microbiology Letters , 188 :165 , 2000
Abstract : A recombinant lipase, CWB-LipB, localized on the Bacillus subtilis cell surface and retaining lipase activity was unstable and not accumulated in a high yield. To improve the accumulation, we examined cell wall binding protease (wprA)- and/or sigma D (sigD)-deficient mutants, and also a NprE and AprA protease-deficient mutant as host strains. The nprE aprA mutation did not lead to a significant increase in the CWB-LipB accumulation. The wprA mutant accumulated a greater amount than the wild-type only in the stationary phase, but the sigD mutant accumulated a greater amount in both the exponential and stationary phases. The double mutant exhibited great accumulation of CWB-LipB, the amount being 36% of the total proteins extracted from the cell surface.

Title : Distribution and Characterization of AKT Homologs in the Tangerine Pathotype of Alternaria alternata - Masunaka_2000_Phytopathology_90_762
Author(s) : Masunaka A , Tanaka A , Tsuge T , Peever TL , Timmer LW , Yamamoto M , Yamamoto H , Akimitsu K

Abstract : ABSTRACT The tangerine pathotype of Alternaria alternata produces a host-selective toxin (HST), known as ACT-toxin, and causes Alternaria brown spot disease of citrus. The structure of ACT-toxin is closely related to AK- and AF-toxins, which are HSTs produced by the Japanese pear and strawberry pathotypes of A. alternata, respectively. AC-, AK-, and AF-toxins are chemically similar and share a 9,10-epoxy-8-hydroxy-9-methyl-decatrienoic acid moiety. Two genes controlling AK-toxin biosynthesis (AKT1 and AKT2) were recently cloned from the Japanese pear pathotype of A. alternata. Portions of these genes were used as heterologous probes in Southern blots, that detected homologs in 13 isolates of A. alternata tangerine pathotype from Minneola tangelo in Florida. Partial sequencing of the homologs in one of these isolates demonstrated high sequence similarity to AKT1 (89.8%) and to AKT2 (90.7%). AKT homologs were not detected in nine isolates of A. alternata from rough lemon, six isolates of nonpathogenic A. alternata, and one isolate of A. citri that causes citrus black rot. The presence of homologs in the Minneola isolates and not in the rough lemon isolates, nonpathogens or black rot isolates, correlates perfectly to pathogenicity on Iyo tangerine and ACT-toxin production. Functionality of the homologs was demonstrated by detection of transcripts using reverse transcription-polymerase chain reaction (RT-PCR) in total RNA of the tangerine pathotype of A. alternata. The high sequence similarity of AKT and AKT homologs in the tangerine patho-type, combined with the structural similarity of AK-toxin and ACT-toxin, may indicate that these homologs are involved in the biosynthesis of the decatrienoic acid moiety of ACT-toxin.

Abstract : Bacillus subtilis is the best-characterized member of the Gram-positive bacteria. Its genome of 4,214,810 base pairs comprises 4,100 protein-coding genes. Of these protein-coding genes, 53% are represented once, while a quarter of the genome corresponds to several gene families that have been greatly expanded by gene duplication, the largest family containing 77 putative ATP-binding transport proteins. In addition, a large proportion of the genetic capacity is devoted to the utilization of a variety of carbon sources, including many plant-derived molecules. The identification of five signal peptidase genes, as well as several genes for components of the secretion apparatus, is important given the capacity of Bacillus strains to secrete large amounts of industrially important enzymes. Many of the genes are involved in the synthesis of secondary metabolites, including antibiotics, that are more typically associated with Streptomyces species. The genome contains at least ten prophages or remnants of prophages, indicating that bacteriophage infection has played an important evolutionary role in horizontal gene transfer, in particular in the propagation of bacterial pathogenesis.

Abstract : The nucleotide sequence of a 9444-bp segment around the 78 degrees region of the Bacillus subtilis (Bs) chromosome has been determined. Nine putative orfs were identified. The deduced amino acid sequences of the products of two of them (yfiJ and yfiK) exhibit high similarity to those of a sensor protein, DegS, and a transcriptional regulatory protein, DegU, of Bs, respectively. Three of them (yfiL, yfiM and yfiN) seem to be ABC transporter genes. One orf (designated as lipB), the closest to the sspE among the nine orfs, is the second lipase gene in Bs.

Title : The effects of 2,5-hexanedione and acrylamide on myosin heavy chain isoforms of slow and fast skeletal muscles of the rat - Oishi_1996_Toxicol.Appl.Pharmacol_139_15
Author(s) : Oishi Y , Yamamoto H , Nagano M , Miyamoto E , Futatsuka M

Abstract : We examined the effects of 2,5-hexanedione (2,5-HD) and acrylamide (ACR) on the muscle fiber types and myosin heavy chain (MHC) isoform composition of the slow-twitch soleus and fast-twitch plantaris muscles of rats. We employed two differently designed experiments with respect to the dosage levels and treatment periods for developing clinical neuropathies. When male Wistar rats were subcutaneously injected with 4.5 mmol of 2,5-HD/kg or 0.4 mmol of ACR/kg, 5 days a week, they developed paralysis of the hindlimbs in 4 weeks (high-dosage experiment). When they were subcutaneously injected with 3.5 mmol of 2,5-HD/kg or 0.35 mmol of ACR/kg, 5 days a week, paralysis of the hindlimbs did not develop until 6 weeks (low-dosage experiment). We examined mainly the rats treated with the neurotoxicants for 4 and 8 weeks in the high-and low-dosage experiments, respectively. Significant decreases in the maximum motor conduction velocity of the sciatic nerves were observed in the hindlimbs of the rats in both experiments. The weights of the soleus and plantaris muscles were significantly reduced in the 2,5-HD-treated rats in both experiments, while in the ACR-treated rats, the weights of both muscles decreased only in the low-dosage experiment. We could not detect any changes in the fiber type composition of the muscles by any of the treatments. However, biochemical analysis revealed decreases in the values (percentage) of the relative amounts of fast-type MHC IIa and IIb isoforms to total MHC isoforms in the 2,5-HD-treated rats, but not in the ACR-treated rats in the high-dosage experiment. In contrast, significant differences in the relative amounts of MHC isoforms were not observed after administration of the low dosage of 2,5-HD. These results suggest that 2,5-HD preferentially disorders the muscle fibers which contain the MHC II isoform. These effects may occur only after the relatively acute intoxication of 2,5-HD at a high dosage.

Abstract : The nucleotide sequence of a 27830-bp DNA segment in the 79 degrees-81 degrees region of the Bacillus subtilis genome has been determined. This region contains 29 complete ORFs including the sspE gene, which encodes a small acid-soluble spore protein gamma and locates on the one side terminal of our assigned region. A homology search for the products deduced from the 29 ORFs revealed that nine of them exhibit significant similarity to known proteins, e.g. proteins involved in an iron uptake system, a multidrug resistance protein, a chloramphenicol resistance protein, epoxide hydrolase, adenine glycosylase, and a glucose-1-dehydrogenase homolog.

Ref : Internal Medicine , 34 :632 , 1995
Abstract : A family with serum cholinesterase (SChE) deficiency is reported. A 64-year-old woman was admitted for the excision of colon adenoma; her laboratory data revealed a markedly decreased level of SChE. SChE genes of the patient and her family members were amplified by the polymerase chain reaction (PCR) and analyzed by direct sequencing. The patient's SChE gene had a homozygous frame shift mutation, in which an extra adenine was inserted in codon 315 (ACC-->AACC), resulting in the appearance of a new stop codon in codon 322. The family study disclosed that her brother and sister had the same frame shift mutations in homozygote and heterozygote, respectively.

Title : Mutations in the unc-41 gene cause elevation of acetylcholine levels - Harada_1994_J.Neurochem_63_439
Author(s) : Harada S , Hori I , Yamamoto H , Hosono R
Ref : Journal of Neurochemistry , 63 :439 , 1994
Abstract : Mutations in the Caenorhabditis elegans unc-41 gene result in an allele-dependent elevation of acetylcholine content. Eight recessive alleles (cn252, e268, e399, e650, e1175, e1199, e1294, and e870) lead to phenotypes including uncoordinated locomotion, slow growth, a small mature body, and resistance to the acetylcholinesterase inhibitors as well as the elevation of acetylcholine content. The remaining two alleles, e554 and e1162, exhibit normal acetylcholine levels but display the short-body phenotype in a semidominant way. To determine the localization of the elevated acetylcholine content, a method for the isolation of synaptic vesicles from C. elegans was established. The elevation of acetylcholine content in the unc-41 mutants is accompanied by the accumulation of synaptic vesicles. We propose that at least one function of the unc-41 gene relates to the release of neurotransmitters.

Author(s) : Kamiya Y , Harada S , Yamamoto H , Hosono R
Ref : Neuroscience Letters , 145 :37 , 1992
Abstract : Acrylamide inhibits growth and results in death in the nematode Caenorhabditis elegans. The lethargic effect is marked in the mutants defective in genes for acetylcholinesterase (AChE) and the effect is approximately parallel with the decrease in AChE activity by mutations. Although neither the activity nor the localization of the enzyme is affected by acrylamide, the acetylcholine level was significantly elevated.
