Porcine kidney microsomal cysteine S-conjugate N-acetyltransferase-catalyzed N-acetylation of haloalkene-derived cysteine S-conjugates. (1/30)

N-Acetylation of xenobiotic-derived cysteine S-conjugates is a key step in the mercapturic acid pathway. The aim of this study was to investigate the N-acetylation of haloalkene-derived S-haloalkyl and S-haloalkenyl cysteine S-conjugates by porcine kidney cysteine S-conjugate N-acetyltransferase (NAcT). A radioactive assay for the quantification of NAcT activity was developed as a new method for partial purification of the enzyme, which was necessitated by the substantial loss of activity during the immunoaffinity chromatography method. 3-[(3-Cholamidopropyl)dimethylammonio]-1-propane-sulfonate, rather than N,N-bis[3-gluconamidopropyl]deoxycholamide, was used to solubilize the NAcT from porcine kidney microsomes in the revised procedure. The partially purified NAcT was free of detectable aminoacylase activity. Although low acetyl-coenzyme A hydrolase activity was observed, its effect on the assay was minimized by addition of excess acetyl-coenzyme A in the NAcT assay mixture. Attempts to separate the residual hydrolase activity from NAcT by different chromatographic procedures were either unsuccessful or lead to inactivation of NAcT. Most of the cysteine S-conjugates studied were N-acetylated by NAcT. Although the apparent K(m) values for the cysteine S-conjugates studied differed by a factor of approximately 2.5 (124-302 microM), a greater than 15-fold difference in the apparent V(max) (0.75-15.6 nmol/h) and V(max)/K(m) (0.008-0.126 x 10(-3) l h(-1)) values was observed. These data show that a range of haloalkene-derived cysteine S-conjugates serve as substrates for pig kidney NAcT. The significant differences in cytotoxicity of these conjugates may be a result of more variable deacetylation rates of the corresponding mercapturates.  (+info)

Molecular cloning and functional expression of rat liver cytosolic acetyl-CoA hydrolase. (2/30)

A cytosolic acetyl-CoA hydrolase (CACH) was purified from rat liver to homogeneity by a new method using Triton X-100 as a stabilizer. We digested the purified enzyme with an endopeptidase and determined the N-terminal amino-acid sequences of the two proteolytic fragments. From the sequence data, we designed probes for RT-PCR, and amplified CACH cDNA from rat liver mRNA. The CACH cDNA contains a 1668-bp ORF encoding a protein of 556 amino-acid residues (62 017 Da). Recombinant expression of the cDNA in insect cells resulted in overproduction of functional acetyl-CoA hydrolase with comparable acyl-CoA chain-length specificity and Michaelis constant for acetyl-CoA to those of the native CACH. Database searching shows no homology to other known proteins, but reveals high similarities to two mouse expressed sequence tags (91% and 93% homology) and human mRNA for KIAA0707 hypothetical protein (50% homology) of unknown function.  (+info)

Production of acetate in the liver and its utilization in peripheral tissues. (3/30)

In experimental rat liver perfusion we observed net production of free acetate accompanied by accelerated ketogenesis with long-chain fatty acids. Mitochondrial acetyl-CoA hydrolase, responsible for the production of free acetate, was found to be inhibited by the free form of CoA in a competitive manner and activated by reduced nicotinamide adenine dinucleotide (NADH). The conditions under which the ketogenesis was accelerated favored activation of the hydrolase by dropping free CoA and elevating NADH levels. Free acetate was barely metabolized in the liver because of low affinity, high K(m), of acetyl coenzyme A (acetyl-CoA) synthetase for acetate. Therefore, infused ethanol was oxidized only to acetate, which was entirely excreted into the perfusate. The acetyl-CoA synthetase in the heart mitochondria was much lower in K(m) than it was in the liver, thus the heart mitochondria was capable of oxidizing free acetate as fast as other respiratory substrates, such as succinate. These results indicate that rat liver produces free acetate as a byproduct of ketogenesis and may supply free acetate, as in the case of ketone bodies, to extrahepatic tissues as fuel.  (+info)

Mouse cytosolic acetyl-CoA hydrolase, a novel candidate for a key enzyme involved in fat metabolism: cDNA cloning, sequencing and functional expression. (4/30)

A cytosolic acetyl-CoA hydrolase (CACH) cDNA has been isolated from mouse liver cDNA library and sequenced. Recombinant expression of the cDNA in insect cells resulted in overproduction of active acetyl-CoA hydrolyzing enzyme protein. The mouse CACH cDNA encoded a 556-amino-acid sequence that was 93.5% identical to rat CACH, suggesting a conserved role for this enzyme in the mammalian liver. Database searching shows no homology to other known proteins, but reveals homological cDNA sequences showing two single-nucleotide polymorphisms (SNPs) in the CACH coding region. The discovery of mouse CACH cDNA is an important step towards genetic studies on the functional analysis of this enzyme by gene-knockout and transgenic approaches.  (+info)

Functional characterization and localization of acetyl-CoA hydrolase, Ach1p, in Saccharomyces cerevisiae. (5/30)

Acetyl-CoA hydrolase (Ach1p), catalyzing the hydrolysis of acetyl-CoA, is presumably involved in regulating intracellular acetyl-CoA or CoASH pools; however, its intracellular functions and distribution remain to be established. Using site-directed mutagenesis analysis, we demonstrated that the enzymatic activity of Ach1p is dependent upon its putative acetyl-CoA binding sites. The ach1 mutant causes a growth defect in acetate but not in other non-fermentable carbon sources, suggesting that Ach1p is not involved in mitochondrial biogenesis. Overexpression of Ach1p, but not constructs containing acetyl-CoA binding site mutations, in ach1-1 complemented the defect of acetate utilization. By subcellular fractionation, most of the Ach1p in yeast was distributed with mitochondria and little Ach1p in the cytoplasm. By immunofluorescence microscopy, we show that Ach1p and acetyl-CoA binding site-mutated constructs, but not its N-terminal deleted construct, are localized in mitochondria. Moreover, the onset of pseudohyphal development in homozygote ach1-1 diploids was abolished. We infer that Ach1p may be involved in a novel acetyl-CoA biogenesis and/or acetate utilization in mitochondria and thereby indirectly affect pseudohyphal development in yeast.  (+info)

Physiological difference between dietary obesity-susceptible and obesity-resistant Sprague Dawley rats in response to moderate high fat diet. (6/30)

The primary aim of the present study was to define central and peripheral physiological differences between dietary obesity-susceptible (DOS) and obesity-resistant (DOR) outbred Sprague Dawley (SD) rats when given a moderate high fat diet containing 32.34% of energy as a fat. After a 9-week feeding period, the DOS-SD rats consumed significantly more feed (11.1%) and had higher abdominal (39.9%) and epididymal (27.5%) fat pads than the DOR-SD rats. In addition, serum leptin and insulin levels were significantly increased in the DOS-SD rats compared with those in the DOR-SD rats. However, we did not observe significant differences in serum triglyceride, cholesterol and glucose. No differences in hypothalamic OB-Ra and Rb mRNA expressions were found between the two groups. In contrast, arcuate NPY immunohistochemical expression was much higher in the DOS-SD rats than in the DOR-SD rats, though NPY expression in the supraoptic and paraventricular nuclei was not different between the two phenotypes. In peripheral tissues, the DOS-SD rats showed noticeably increased acetyl CoA carboxylase (ACC) mRNA expression in the liver, not epididymal fat. However, Western blot of peroxisomal proliferator activated factor gamma (PPAR gamma) in the liver and epididymal fat was not different between the two phenotypes of SD rats. It was concluded that different body weight phenotypes within outbred SD population responded differently to the development of dietary induced obesity via altered anabolic features in the hypothalamus and liver.  (+info)

An acetate-sensitive mutant of Neurospora crassa deficient in acetyl-CoA hydrolase. (7/30)

The predicted amino acid sequence of the product of the acetate-inducible acu-8 gene of Neurospora crassa, previously of unknown function, has close homology to the recently published sequence of Saccharomyces cerevisiae acetyl-CoA hydrolase. An acu-8 mutant strain, previously characterized as acetate non-utilizing, shows strong growth-inhibition by acetate, but will use it as carbon source at low concentrations. The mutant was shown to be deficient in acetyl-CoA hydrolase and to accumulate acetyl-CoA when supplied with acetate. As in Saccharomyces, the Neurospora enzyme is acetate-inducible.  (+info)

Brassica juncea 3-hydroxy-3-methylglutaryl (HMG)-CoA synthase 1: expression and characterization of recombinant wild-type and mutant enzymes. (8/30)

3-hydroxy-3-methylglutaryl (HMG)-CoA synthase (HMGS; EC 2.3.3.10) is the second enzyme in the cytoplasmic mevalonate pathway of isoprenoid biosynthesis, and catalyses the condensation of acetyl-CoA with acetoacetyl-CoA (AcAc-CoA) to yield S-HMG-CoA. In this study, we have first characterized in detail a plant HMGS, Brassica juncea HMGS1 (BjHMGS1), as a His6-tagged protein from Escherichia coli. Native gel electrophoresis analysis showed that the enzyme behaves as a homodimer with a calculated mass of 105.8 kDa. It is activated by 5 mM dithioerythreitol and is inhibited by F-244 which is specific for HMGS enzymes. It has a pH optimum of 8.5 and a temperature optimum of 35 degrees C, with an energy of activation of 62.5 J x mol(-1). Unlike cytosolic HMGS from chicken and cockroach, cations like Mg2+, Mn2+, Zn2+ and Co2+ did not stimulate His6-BjHMGS1 activity in vitro; instead all except Mg2+ were inhibitory. His6-BjHMGS1 has an apparent K(m-acetyl-CoA) of 43 microM and a V(max) of 0.47 micromol x mg(-1) x min(-1), and was inhibited by one of the substrates (AcAc-CoA) and by both products (HMG-CoA and HS-CoA). Site-directed mutagenesis of conserved amino acid residues in BjHMGS1 revealed that substitutions R157A, H188N and C212S resulted in a decreased V(max), indicating some involvement of these residues in catalytic capacity. Unlike His6-BjHMGS1 and its soluble purified mutant derivatives, the H188N mutant did not display substrate inhibition by AcAc-CoA. Substitution S359A resulted in a 10-fold increased specific activity. Based on these kinetic analyses, we generated a novel double mutation H188N/S359A, which resulted in a 10-fold increased specific activity, but still lacking inhibition by AcAc-CoA, strongly suggesting that His-188 is involved in conferring substrate inhibition on His6-BjHMGS1. Substitution of an aminoacyl residue resulting in loss of substrate inhibition has never been previously reported for any HMGS.  (+info)

A Saccharomyces cerevisiae strain carrying deletions in all three pyruvate decarboxylase genes (also called Pdc negative yeast) represents a non-ethanol producing platform strain for biochemical production. However, it cannot grow on glucose as the sole carbon source due to the lack of cytosolic acetyl-CoA for lipid biosynthesis. Its growth inability on glucose could be restored through directed evolution, which was explained by an in-frame internal deletion in MTH1 (MTH1-∆T). The MTH1-∆T allele resulted in reduced glucose uptake, which may attenuate the repression of respiratory metabolism. However, it was not clear what mechanism could provide the cells with sufficient precursors for cytosolic acetyl-CoA. Here we investigated this using a Pdc negative strain with MTH1-∆T, IMI076. Our results identified a route relying on Ach1 that could transfer acetyl units from mitochondria to the cytoplasm. Based on the results a new model was proposed, in which acetyl units are shuttled from the mitochondria

Of Susanna Radovic from F & F 2009. I remain the same person ony a part of my brain is replaced by a computer chip?. If it were possible, would you have to implant a computer chip in the brain that helped you to remember better? Or to concentrate long periods at a time, or smoothing any mood swings?. Today you can improve and modify the damaged cognitive and mental ability of medical means. But scientists are also on track to develop brain prosthesis, that is, artificial implants that can take over a damaged brain function. If Alzheimers disease has damaged the part of the brain that is responsible for storage of new memories, would simply be able to replace it with a prosthesis, a computer chip that works on the same principle as the brain itself and that can communicate with the brains nerve cells. Similar procedures could also replace other parts of the brain with artificial prostheses.. The development of new methods in medical research raises many ethical problems. Such is the case also ...

Production of the biopolymer polyhydroxybutyrate (PHB) in Saccharomyces cerevisiae starts at the end of exponential phase particularly when the specific growth rate is decreased due to the depletion of glucose in the medium. The specific growth rate and the type of carbon source (fermentable/non-fermentable) have been known to influence the cell physiology and hence affect the fermentability of S. cerevisiae. The production of PHB utilizes cytosolic acetyl-CoA as a precursor and the S. cerevisiae employed in this study is therefore a strain with the enhanced cytosolic acetyl-CoA supply. Growth and PHB production at different specific growth rates were evaluated on glucose, ethanol and a mixture of glucose and ethanol as carbon source. Ethanol as carbon source yielded a higher PHB production compared to glucose since it can be directly used for cytosolic acetyl-CoA production and hence serves as a precursor for PHB production. However, this carbon source results in lower biomass yield and hence it was
In animals, fatty acids are formed from carbohydrates predominantly in the liver, adipose tissue, and the mammary glands during lactation.[16]. Carbohydrates are converted into pyruvate by glycolysis as the first important step in the conversion of carbohydrates into fatty acids.[16] Pyruvate is then decarboxylated to form acetyl-CoA in the mitochondrion. However, this acetyl CoA needs to be transported into cytosol where the synthesis of fatty acids occurs. This cannot occur directly. To obtain cytosolic acetyl-CoA, citrate (produced by the condensation of acetyl-CoA with oxaloacetate) is removed from the citric acid cycle and carried across the inner mitochondrial membrane into the cytosol.[16] There it is cleaved by ATP citrate lyase into acetyl-CoA and oxaloacetate. The oxaloacetate is returned to the mitochondrion as malate.[17] The cytosolic acetyl-CoA is carboxylated by acetyl CoA carboxylase into malonyl-CoA, the first committed step in the synthesis of fatty acids.[17][18]. Malonyl-CoA ...

The discourse marker cachái (ysee?) has in a rather short time span become one of the most frequently used in colloquial Chilean Spanish, especially in the talk of young speakers. Being a recent addition to the language, it is not surprising that the history and use of the marker remain in large part to be described. The etymology which is commonly presented (Real Academia Española, 2014, s.v. cachar), according to which cachar is a loan of the English verb catch, is problematic as it fails to account for the uses attested for cachái in modern Chilean Spanish. The present study adopts a historical pragmatic perspective to track the development of the verb, proposing an alternative origin, namely in the verb catar (look (for), see). By contrasting this explanation with authentic, situated, uses of cachái, the study argues that such an origin can account for the uses we see today more adequately and convincingly.. ...
The ward management module is a one stop summary display that could be of great benefit in other environments, Howes explains. Aside from delivering functionality that benefits patients, we have also been able to provide a proof-of-concept that demonstrates how simplified integration using Caché can reduce costs. These systems can be implemented for under 2,000 per ward, instead of implementation costs running up to tens of thousands for other similar systems.. According to Jonathan Selby, Country Manager UK & Ireland at InterSystems, this sums up perfectly the value of the work that Robin Howes and his team have been able to achieve. Northern Lincolnshire and Goole Hospitals NHS Foundation Trusts WebV is an excellent example of how Caché facilitates the delivery of timely patient care. We are extremely pleased that the Trust has used its in-house development skills to produce this excellent portal. Caché is the core technology for all of InterSystems healthcare offerings, including the ...

Discussion:. Energetics in animals is based on the availability of reducing equivalents, specifically hydrogen (H+) which is replenished byconsumed as carbohydrates and fats, that react with oxygen to generate water and hydrogen via mitochondrial oxidative phosphorylation.. The older evolutionary pathways makes far less energy than complex animals need for chronic living. Glucose is cleaved into pyruvate via glycolysis within the cytosol, reducing cytosolic NAD+ to NADH (reduced nicotinamide adenine nucleotide). The pyruvate then enters the mitochondrion via pyruvate dehydrogenase (PDH), resulting in mitochondrial acetyl-CoA (main electron provider for ECT), NADH + H+, and CO2. The acetyl-CoA then enters the tricarboxylic acid (TCA) cycle, which strips the hydrogens from the organic acids, thereby generating NADH + H+.. The new pathways (beta oxidation) are required for complex life because they provide a lot more electrons for tunneling. The more electrons the more life you live.. Fatty acids ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We present the design, implementation, and evaluation of Caché, a system that offers location privacy for certain classes of location-based applications. The core idea in Caché is to periodically pre-fetch potentially useful location-enhanced content well in advance. Applications then retrieve content from a local cache on the mobile device when it is needed. This approach allows the end-user to make use of locationenhanced content while only revealing to third-party content providers what geographic region she is in rather than her precise location. In this paper, we present an analysis that examines tradeoffs in terms of storage, bandwidth, and freshness of data. We then discuss the design and implementation of an Android service embodying these ideas. Finally, we provide two evaluations of Caché. One measures the performance of our approach with respect to privacy and mobile content availability using real-world mobility

Objective Fatty acid oxidation in macrophages is thought to regulate inflammatory status and insulin-sensitivity. fatty acids and are required for fatty acid oxidation [13]. Carnitine O-octanoyltransferase (CrOT) and carnitine acetyltransferase (CrAT) conjugate medium-chain and short-chain acyl-CoA to carnitine, respectively [13]. CrAT is localized primarily within the mitochondrial matrix and catalyzes both the addition and the removal of carnitine from acetyl-CoA [14], facilitating the efflux of mitochondrial acetyl-CoA and buffering the intracellular pools of acetyl-CoA and carnitine. Consistent with an important role of fatty acid oxidation in macrophages, CPT1, CPT2, Crat and Crot are abundantly expressed in macrophages [15]. Interestingly, the CrAT activity is reduced during obesity and aging, leading to impaired glycemic control [16], [17]. Notably, muscle-specific deletion of CrAT was shown to reduce exercise performance [18] and exacerbated metabolic dysregulation in HFD mice [19]. ...

Po tych wszystkich niesamowicie długich miesiącach, a właściwie nawet całych latach (!) rozłąki z moim skromnym kątem w sieci, postanowiłam zawitać w te stare, tak dawno nieodwiedzane progi. Skłamałabym mówiąc, że nie tęskniłam i choć naprawdę mocno odczuwałam tą ciągnącą się w nieskończoność przerwę, postanowiłam powrócić z treściami zupełnie innego typu - w nowych fotorelacjach oczywiście na pewno nie zabraknie mody, ale... Mam nadzieję, że będzie ona w nieco bardziej przemyślanych i dojrzalszych formach, bardziej dopracowanej postaci i zupełnie innym, fotograficznym wymiarze. Tym razem, chciałabym skupić się na tym, co mnie otacza, a nie wyłącznie na sobie. Zakochałam się w minimalizmie, niewymuszonej elegancji i naturalnym uroku i chciałabym Wam tę fascynację nieco przybliżyć ;) W formie zdjęć z sesji mojego autorstwa, reportaży z podróży, ulicznych wywiadów ...

Objective Fatty acid oxidation in macrophages is thought to regulate inflammatory status and insulin-sensitivity. fatty acids and are required for fatty acid oxidation [13]. Carnitine O-octanoyltransferase (CrOT) and carnitine acetyltransferase (CrAT) conjugate medium-chain and short-chain acyl-CoA to carnitine, respectively [13]. CrAT is localized primarily within the mitochondrial matrix and catalyzes both the addition and the removal of carnitine from acetyl-CoA [14], facilitating the efflux of mitochondrial acetyl-CoA and buffering the intracellular pools of acetyl-CoA and carnitine. Consistent with an important role of fatty acid oxidation in macrophages, CPT1, CPT2, Crat and Crot are abundantly expressed in macrophages [15]. Interestingly, the CrAT activity is reduced during obesity and aging, leading to impaired glycemic control [16], [17]. Notably, muscle-specific deletion of CrAT was shown to reduce exercise performance [18] and exacerbated metabolic dysregulation in HFD mice [19]. ...
The main function of Acetyl-CoA is to carry acyl groups or thioesters. It is the precursor to HMG CoA, an important part of cholesterol and ketone synthesis. It can also be found as a vital reagent in the synthesis of fatty acids and sterols, as well as the oxidation of fatty acids as well as the breaking down of many amino acids. [2] Acetyl-CoA is well known as the junction between Glycolysis and the Citric Acid Cycle as well as an essential component in balancing between carbohydrate and fat metabolism. Acetyl-CoA has also been a central metabolite that is involved in many metabolic transformations within the cell. The acetyl group of the acetyl-CoA is used to oxidize via the TCA cycle to reduce NAD+ and FAD to NADH and FADH2, respectively. These products are then used to fuel ATP production through the electron transport train. In May 2011, Ling Cai et al. found that Acetyl-Coa functioned as a carbon-source rheostat that signals the initiation of the cellular growth program by promoting the ...

Kiedy znalazłem tego newsa na stronie www.kyivpost.com, pomyślałem, że zapewne zainteresuje on kilku polskich tolkienistów. Oto już wkrótce, na ukraińskim rynku wydawniczym, pojawi się ukraińskie wydanie ostatniej książki J.R.R Tolkiena - Children of Húrin.. Przekładem zajęła się Kateryna Onyschuk z Lwowa, która jak sama przyznała, w okresie tłumaczenia książki, śniła o elfach, i gnomach pomagających jej w wybraniu najlepszego z przekładów.. Do niedawna nie było pewne, który przekład ukaże się pierwszy, rosyjski czy ukraiński. Okazało się jednak, iż małe ukraińskie wydawnictwo - Astroliabi (które powstało w 2001 roku), poradziło sobie z tłumaczeniem powieści szybciej niż potężny rosyjski AST, zapowiadający wydanie książki w najbliższych miesiącach. Jak podkreśla Oleh Feshovets - dyrektor Astroliabi- taki właśnie był plan. Plan rzeczywiście sprytny, jako że wydawca zapewne zyska wiele poprzez wydanie Children of Húrin na ukraińskim rynku, ...

Due to its tendency to recur and acquire chemoresistance quickly, bladder cancer (BC) remains to be an elusive and difficult disease. Patients with recurrent and chemoresistant BC have an extremely poor prognosis. One possible approach that may provide insightful and valuable information regarding resistance mechanisms is looking into the lipid metabolism of BC cells. Metabolism of lipids is essential for cancer cells and is associated with the regulation of a variety of key cellular processes and functions. This study conducted a comparative lipidomic profiling of two isogenic human T24 bladder cancer cell lines, one of which is clinically characterized as cisplatin-sensitive (T24S) and the other as cisplatin-resistant (T24R). Immunohistochemistry analysis revealed that expression of cytosolic acetyl-CoA synthetase 2 (ACSS2) is positively correlated with aggressive BC. Ultra performance liquid chromatography-mass spectrometry (UPLC-MS) analysis profiled a total of 1,864 lipids and levels of
