GABA-Induced Cl- current in cultured embryonic human dorsal root ganglion neurons. (2/82)

gamma-Aminobutyric acid (GABA)-activated channels in embryonic (5-8 wk old) human dorsal root ganglion (DRG) neurons in dissociated culture were characterized by whole cell and single-channel techniques. All DRG neurons when held at negative holding membrane potentials displayed inward current to micromolar concentrations of GABA applied by pressure pulses from closely positioned micropipettes. The current was directly proportional to the concentration of GABA (EC50, 111 microM; Hill coefficient, 1.7). DRG neurons also responded to micromolar concentrations of pentobarbital and alphaxalone but not to cis-4-aminocrotonic acid (CACA), glycine, or taurine. Baclofen (100 microM) affected neither the holding currents nor K+ conductance (when patch pipettes were filled with 130 mM KCl) caused by depolarizing pulses. Whole cell GABA-currents were blocked by bicuculline, picrotoxin, and t-butylbicyclophosphorothionate (TBPS; all at 100 microM). The reversal potential of whole cell GABA-currents was close to the theoretical Cl- equilibrium potential, shifting with changes in intracellular Cl- concentration in a manner expected for Cl--selective channels. The whole cell I-V curve for GABA-induced currents demonstrated slight outward rectification with nearly symmetrical outside and inside Cl- concentrations. Spectral analysis of GABA-induced membrane current fluctuations showed that the kinetic components were best fitted by a triple Lorentzian function. The apparent elementary conductance for GABA-activated Cl- channels determined from the power spectra was 22.6 pS. Single-channel recordings from cell-attached patches with pipettes containing 10 microM GABA indicated that GABA-activated channels have a main and a subconductance level with values of 30 and 19 pS, respectively. Mean open and closed times of the channel were characterized by two or three exponential decay functions, suggesting two or three open channel states and two closed states. Single channels showed a lack of rectification. The actions of GABA on cultured human embryonic DRG neurons are mediated through the activation of GABAA receptors with properties corresponding to those found in the CNS of human and other mammalian species but differing from those of cultured human adult DRG neurons.  (+info)

Three GABA receptor-mediated postsynaptic potentials in interneurons in the rat lateral geniculate nucleus. (3/82)

Inhibition is crucial for the thalamus to relay sensory information from the periphery to the cortex and to participate in thalamocortical oscillations. However, the properties of inhibitory synaptic events in interneurons are poorly defined because in part of the technical difficulty of obtaining stable recording from these small cells. With the whole-cell recording technique, we obtained stable recordings from local interneurons in the lateral geniculate nucleus and studied their inhibitory synaptic properties. We found that interneurons expressed three different types of GABA receptors: bicuculline-sensitive GABA(A) receptors, bicuculline-insensitive GABA(A) receptors, and GABA(B) receptors. The reversal potentials of GABA responses were estimated by polarizing the membrane potential. The GABA(A) receptor-mediated responses had a reversal potential of approximately -82 mV, consistent with mediation via Cl(-) channels. The reversal potential for the GABA(B) response was -97 mV, consistent with it being a K(+) conductance. The roles of these GABA receptors in postsynaptic responses were also examined in interneurons. Optic tract stimulation evoked a disynaptic IPSP that was mediated by all three types of GABA receptors and depended on activation of geniculate interneurons. Stimulation of the thalamic reticular nucleus evoked an IPSP, which appeared to be mediated exclusively by bicuculline-sensitive GABA(A) receptors and depended on the activation of reticular cells. The results indicate that geniculate interneurons form a complex neuronal circuitry with thalamocortical and reticular cells via feed-forward and feedback circuits, suggesting that they play a more important role in thalamic function than thought previously.  (+info)

Role of crotonyl coenzyme A reductase in determining the ratio of polyketides monensin A and monensin B produced by Streptomyces cinnamonensis. (4/82)

The ccr gene, encoding crotonyl coenzyme A (CoA) reductase (CCR), was cloned from Streptomyces cinnamonensis C730.1 and shown to encode a protein with 90% amino acid sequence identity to the CCRs of Streptomyces collinus and Streptomyces coelicolor. A ccr-disrupted mutant, S. cinnamonensis L1, was constructed by inserting the hyg resistance gene into a unique BglII site within the ccr coding region. By use of the ermE* promoter, the S. collinus ccr gene was expressed from plasmids in S. cinnamonensis C730. 1/pHL18 and L1/pHL18. CCR activity in mutant L1 was shown to decrease by more than 90% in both yeast extract-malt extract (YEME) medium and a complex fermentation medium, compared to that in wild-type C730.1. Compared to C730.1, mutants C730.1/pHL18 and L1/pHL18 exhibited a huge increase in CCR activity (14- and 13-fold, respectively) in YEME medium and a moderate increase (3.7- and 2. 7-fold, respectively) in the complex fermentation medium. In the complex fermentation medium, S. cinnamonensis L1 produced monensins A and B in a ratio of 12:88, dramatically lower than the 50:50 ratio observed for both C730.1 and C730.1/pHL18. Plasmid (pHL18)-based expression of the S. collinus ccr gene in mutant L1 increased the monensin A/monensin B ratio to 42:58. Labeling experiments with [1, 2-(13)C(2)]acetate demonstrated the same levels of intact incorporation of this material into the butyrate-derived portion of monensin A in both C730.1 and mutant C730.1/pLH18 but a markedly decreased level of such incorporation in mutant L1. The addition of crotonic acid at 15 mM led to significant increases in the monensin A/monensin B ratio in C730.1 and C730.1/pHL18 but had no effect in S. cinnamonensis L1. These results demonstrate that CCR plays a significant role in providing butyryl-CoA for monensin A biosynthesis and is present in wild-type S. cinnamonensis C730.1 at a level sufficient that the availability of the appropriate substrate (crotonyl-CoA) is limiting.  (+info)

Independence of and interactions between GABA-, glutamate-, and acetylcholine-activated Cl conductances in Aplysia neurons. (5/82)

In certain Aplysia neurons, glutamate, GABA, and acetylcholine (ACh) all elicit desensitizing Cl-dependent responses. This fact and the finding that the glutamate and GABA responses "cross-desensitize" led to the suggestion (Swann and Carpenter, 1975; King and Carpenter, 1987) that the responses to these transmitters were mediated by the same receptor-channel complex. This hypothesis is incompatible with the demonstration given here that the GABA- and glutamate-gated channels are clearly distinct; the GABA channel, but not the glutamate channel, shows outward rectification (Matsumoto, 1982; King and Carpenter, 1987, 1989) and is selectively blocked by intracellular sulfate. Exploiting these distinctive characteristics and the independent expression of the receptors in some cells, we have been able to reevaluate the so-called cross-desensitization by analyzing the ability of GABA, glutamate, and other agonists to interact with each of the receptor molecules. The cross-desensitization was found to be exclusively attributable to the ability of GABA to interact with the glutamate receptor (Oyama et al., 1990). The GABA receptor is unaffected by glutamate. Nevertheless, in cells expressing both receptors, glutamate can reduce the GABA response by auto-desensitizing the part of the response that is mediated by the glutamate receptor. No interactions were observed between ACh-induced responses and either of the responses elicited by the amino acids. The invertebrate glutamate-gated Cl channels that have been cloned resemble the vertebrate glycine receptor (Vassilatis et al., 1997). Our pharmacological evaluation of the molluscan glutamate receptor points in the same direction.  (+info)

Assignment of fatty acid-beta-oxidizing syntrophic bacteria to Syntrophomonadaceae fam. nov. on the basis of 16S rRNA sequence analyses. (6/82)

After enrichment from Chinese rural anaerobic digestor sludge, anaerobic, sporing and nonsporing, saturated fatty acid-beta-oxidizing syntrophic bacteria were isolated as cocultures with H2- and formate-utilizing Methanospirillum hungatei or Desulfovibrio sp. strain G-11. The syntrophs degraded C4 to C8 saturated fatty acids, including isobutyrate and 2-methylbutyrate. They were adapted to grow on crotonate and were isolated as pure cultures. The crotonate-grown pure cultures alone did not grow on butyrate in either the presence or the absence of some common electron acceptors. However, when they were reconstituted with M. hungatei, growth on butyrate again occurred. In contrast, crotonate-grown Clostridium kluyveri and Clostridium sticklandii, as well as Clostridium sporogenes, failed to grow on butyrate when these organisms were cocultured with M. hungatei. The crotonate-grown pure subcultures of the syntrophs described above were subjected to 16S rRNA sequence analysis. Several previously documented fatty acid-beta-oxidizing syntrophs grown in pure cultures with crotonate were also subjected to comparative sequence analyses. The sequence analyses revealed that the new sporing and nonsporing isolates and other syntrophs that we sequenced, which had either gram-negative or gram-positive cell wall ultrastructure, all belonged to the phylogenetically gram-positive phylum. They were not closely related to any of the previously known subdivisions in the gram-positive phylum with which they were compared, but were closely related to each other, forming a new subdivision in the phylum. We recommend that this group be designated Syntrophomonadaceae fam. nov.; a description is given.  (+info)

Biotin-response organicaciduria. Multiple carboxylase defects and complementation studies with propionicacidemia in cultured fibroblasts. (7/82)

Fibroblast cultures from two individuals with biotin-responsive organicacidemia were found to have a pleiotropic deficiency of propionyl-CoA carboxylase, beta-methylcrotonyl-CoA carboxylase, and pyruvate carboxylase activities after growth in biotin limited culture medium, conditions which do not affect the carboxylase activities of normal cells. All three enzyme activities were restored to normal levels after transferring the mutant strains to biotin-rich medium. Both patients excreted abnormal levels of an array of metabolic intermediates, including beta-methylcrotonate, beta-hydroxyisovalerate, beta-hydroxypropionate, and lactate, which reflect metabolic blocks at all three carboxylase sites.14 mutants deficient in only propionyl-CoA carboxylase activity from patients with propionicacidemia and the two biotin-responsive strains were examined for complementation with seven previously mapped pcc mutants. No new pcc complementation groups were identified. Nine of the mutants were mapped to group pccA. The remaining 12 mutants mapped to pccBC or its B or C subgroups, confirming the complex nature of this group. The biotin-responsive mutants failed to complement each other but did complement mutants from all the pcc groups. Thus biotin-responsive organicacidemia is defined by a new complementation group, bio. The results obtained in this study suggest that the bio mutants have a defect of either biotin transport or a common holocarboxylase synthetase required for the biotin activation of all three mitochondrial carboxylases.  (+info)

Substrate stereochemistry of the enoyl-CoA hydratase reaction. (8/82)

1. A specimen of stereospecifically 2-tritiated 3-hydroxybutyric acid was prepared by hydroboration of ethyl crotonate. It was assumed that the hydroboration reaction took a syn course and hence that (2R,3S) plus (2S,3R)-3-hydroxy[2 minus 3H1]butyric acid was formed after oxidation and hydrolysis. 2. 3RS-3-Hydroxy[2 minus 3H2]butyric acid, symmetrically tritiated at C-2, was prepared by isotopic exchange of ethyl acetoacetate in tritiated water, followed by reduction and hydrolysis. 3. The 3R-enantiomers of the acids listed under paragraphs (1) and (2) were destroyed enzymically by use of 3R-specific 3-hydroxybutyrate dehydrogenase and the residual 3S-enantiomers were isolated. 4. The resulting specimens of 2R,3S-3-hydroxy[2 minus 3H1]butyric acid and 3S-3hydroxy[2 minus 3H2]-butyric acid were converted chemically to the acyl-CoA derivatives. These were incubated with enoyl-CoA hydratase. 5. In the presence of the enoyl-CoA hydratase symmetrically labelled 3S-3-hydroxy[2 minus 3H2]BUTYRYL-CoA lost nearly 50% of its tritium label; 2R,3S-3hydroxy [2-3-H1]butyryl-CoA lost about 78%. 6. It was concluded that the elimination of the elements of water from 3-hydroxybutyryl-CoA on the hydratase occurs stereospecifically with syn geometry.  (+info)

Syntrophus aciditrophicusis a model syntrophic bacterium that degrades key intermediates in anaerobic decomposition, such as benzoate, cyclohexane-1-carboxylate, and certain fatty acids, to acetate when grown with hydrogen-/formate-consuming microorganisms. ATP formation coupled to acetate production is the main source for energy conservation byS. aciditrophicus. However, the absence of homologs for phosphate acetyltransferase and acetate kinase in the genome ofS. aciditrophicusleaves it unclear as to how ATP is formed, as most fermentative bacteria rely on these two enzymes to synthesize ATP from acetyl coenzyme A (CoA) and phosphate.

The citrate cycle (TCA cycle, Krebs cycle) is an important aerobic pathway for the final steps of the oxidation of carbohydrates and fatty acids. The cycle starts with acetyl-CoA, the activated form of acetate, derived from glycolysis and pyruvate oxidation for carbohydrates and from beta oxidation of fatty acids. The two-carbon acetyl group in acetyl-CoA is transferred to the four-carbon compound of oxaloacetate to form the six-carbon compound of citrate. In a series of reactions two carbons in citrate are oxidized to CO2 and the reaction pathway supplies NADH for use in the oxidative phosphorylation and other metabolic processes. The pathway also supplies important precursor metabolites including 2-oxoglutarate. At the end of the cycle the remaining four-carbon part is transformed back to oxaloacetate. According to the genome sequence data, many organisms seem to lack genes for the full cycle [MD:M00009], but contain genes for specific segments [MD:M00010 M00011 ...

In the late 1960s, a vibrant new research field was ignited by the discovery that instead of fixing CO(2) into a C(3) compound, some plants initially fix CO(2) into a four-carbon (C(4)) compound. The term C(4) photosynthesis was born. In the 20 years that followed, physiologists, biochemists, and molecular and developmental biologists grappled to understand how the C(4) photosynthetic pathway was partitioned between two morphologically distinct cell types in the leaf. By the early 1990s, much was known about C(4) biochemistry, the types of leaf anatomy that facilitated the pathway, and the patterns of gene expression that underpinned the biochemistry. However, virtually nothing was known about how the pathway was regulated. It should have been an exciting time, but many of the original researchers were approaching retirement, C(4) plants were proving recalcitrant to genetic manipulation, and whole-genome sequences were not even a dream. In combination, these factors led to reduced funding and the
Teriflunomide (trade name Aubagio, marketed by Sanofi) is the active metabolite of leflunomide. Teriflunomide was investigated in the Phase III clinical trial TEMSO as a medication for multiple sclerosis (MS). The study was completed in July 2010. 2-year results were positive. However, the subsequent TENERE head-to-head comparison trial reported that although permanent discontinuations [of therapy] were substantially less common among MS patients who received teriflunomide compared with interferon beta-1a, relapses were more common with teriflunomide. The drug was approved by the FDA on September 13, 2012 and in the European Union on August 26, 2013. Teriflunomide is an immunomodulatory drug inhibiting pyrimidine de novo synthesis by blocking the enzyme dihydroorotate dehydrogenase. It is uncertain whether this explains its effect on MS lesions. Teriflunomide inhibits rapidly dividing cells, including activated T cells, which are thought to drive the disease process in MS. Teriflunomide may ...

Teriflunomide for the treatment of relapsing–remitting multiple sclerosis: patient preference and adherence Antonios Bayas,1 Mathias Mäurer2 1Department of Neurology, Klinikum Augsburg, Augsburg, Germany; 2Department of Neurology, Caritas Krankenhaus Bad Mergentheim, Bad Mergentheim, Germany Abstract: Multiple sclerosis (MS), a chronic demyelinating neuroinflammatory disease of the central nervous system, is the most common neurological disorder leading to disability in young adulthood. In the last 2 decades, numerous treatments for relapsing–remitting MS have been approved with eleven treatment options available worldwide. One of the determinants in treatment selection is disease activity in the individual patient. However, patient preferences play an increasingly major role in treatment decision making. With teriflunomide, a reversible inhibitor of the enzyme dihydroorotate dehydrogenase, a new oral therapeutic option, given once daily, has been approved within the last 2 years
This was a randomized, double-blind, double-dummy, active comparatorcontrolled, parallel-group, multi-center study with variable treatment duration in approximately 900 patients with relapsing multiple sclorosis (RMS). The maximal treatment duration in the study for an individual patient was 2.5 years. Eligible patients were randomized to receive either experimental ofatumumab subcutaneous (s.c.) injections every 4 weeks or active comparator teriflunomide orally once daily. The dose regimen for ofatumumab for this study was a loading dose regimen of 20 mg at Day 1, Day 7 and Day 14, followed by a maintenance dose regimen of 20 mg administered every 4 weeks starting at Week 4. In order to blind for the different formulations, double-dummy masking was used i.e. all patients will take injections (containing either active ofatumumab or placebo) and oral capsules (containing either active teriflunomide or placebo ...

Teriflunomide has various disadvantages, including its potential for liver toxicity, which is why monthly liver function testing is required for the first 6 months of use. Infections may result from a decrease in white blood cell counts, and hypertension, elevated potassium, and acute renal failure have also been associated with this medication.6 Other common adverse reactions include hair thinning, influenza, diarrhea, nausea, and paresthesia.8 Caution should be used in diabetic patients and those over the age of 60 years. Teriflunomide has been assigned pregnancy category X by the FDA; women should not become pregnant and men should not father a child while taking the drug.6 Finally, the half-life of teriflunomide is 2 weeks, but the drug may be present in some patients for as long as 2 years after discontinuation (cholestyramine or activated charcoal hastens elimination).6. Dimethyl fumarate. The mechanism of action for dimethyl fumarates benefit in patients with MS is currently unknown.12 ...

Two novel anaerobes, strains GB4-38T and SB9-1, were isolated from an upflow anaerobic sludge blanket reactor for treating bean-curd farm wastewater and lotus field mud, respectively. The strains degraded straight-chain fatty acids with 4-8 carbon atoms in syntrophic association with methanogens and converted 1 mol butyrate into about 2 mol acetate and presumably 2 mol H2. None of the branched-chain fatty acids tested could be degraded. Benzoate was not degraded. Fumarate, sulfate, thiosulfate, sulfur and nitrate did not serve as electron acceptors for butyrate degradation. In the absence of a methanogen partner, strain GB4-38T grew on crotonate in pure culture; the generation time was about 5 h at 37 °C. However, strain SB9-1 grew on butyrate plus pentenoate, but not crotonate, in pure culture and the generation time was 18 h at 37 °C. Cells of GB4-38T and SB9-1 were straight rods and stained Gram-negative. The major cellular fatty acids of GB4-38T were C14 : 0 (29·74 %), C16 : 0 (17·00 %), C16 : 1
We included 10 randomised trials, eight open-label extension studies (OLEs) and four cohort studies published between 2010 and 2016. The overall risk of bias was high and the reporting of AEs was scarce. The quality of the evidence associated with the results ranges from low to very low.. Early treatment versus placebo during the first 24 months follow-up There was a small, non-significant advantage of early treatment compared with placebo in disability-worsening (6.4% fewer (13.9 fewer to 3 more) participants with disability-worsening with interferon beta-1a (Rebif®) or teriflunomide) and in relapses (10% fewer (20.3 fewer to 2.8 more) participants with relapses with teriflunomide). Early treatment was associated with 1.6% fewer participants with at least one serious AE (3 fewer to 0.2 more). Participants on early treatment were on average 4.6% times (0.3 fewer to 15.4 more) more likely to withdraw from the study due to AEs. This result was mostly driven by studies on interferon beta 1-b, ...

A number of natural products from marine sponges, such as cyclodepsipeptides, have been identified. The structural characteristics of this family of cyclic peptides include various unusual amino acid residues and unique N-terminal polyketide-derived moieties. Papuamides are representatives of a class of marine sponge derived cyclic depsipeptides, including callipeltin A, celebesides A and B, homophymine A, mirabamides, microspinosamide, neamphamide A and theopapuamides. They are thought to have cytoprotective activity against HIV-1 in vitro by inhibiting viral entry. Jasplakinolide, a representative member of marine sponge-derived cyclodepsipeptides that include arenastatin A, geodiamolides, homophymines, spongidepsin and theopapuamides, is a potent inducer of actin polymerization in vitro. Although actin dynamics is essential for tumor metasasis, no actin targeting drugs have been used in clinical trials due to their severe cytotoxicity. Nonetheless, the actin cytoskeleton remains a potential target

Novartis has revealed new post hoc data for its multiple sclerosis (MS) therapy Kesimpta only a few weeks after the drug received approval from the European Commission. New analysis from the phase 3 ASCLEPIOS trials found that Kesimpta (ofatumumab) cut the risk of disability progression independent of relapse activity (PIRA) by up to 60% at three and six months when compared to Sanofis Aubagio (teriflunomide) in a subgroup of newly diagnosed, treatment-naive patients with relapsing multiple sclerosis (RMS).. The PIRA analysis also showed that over 50% of disability worsening events experienced by newly diagnosed and treatment-naive RMS patients occurred regardless of whether they also experienced relapses.. Kesimpta reduced this risk of progression by up to almost 60% versus teriflunomide, reinforcing the importance of early intervention with high-efficacy treatment to address underlying disease progression before irreversible damage occurs, commented Jacqueline Nicholas, system chief ...
In this study, we investigated the effect of Teri and MMF in the context of HIV-mediated monocyte/microglial inflammation due to their well characterized anti-inflammatory properties. The ultimate goal was to reduce inflammation-related neurotoxicity. We demonstrate that Teri and MMF lead to reduced chemotactic and pro-inflammatory cytokine secretion in a co-culture system of microglia with HIV-transduced monocytoid cells. This was associated with reduced neurotoxicity of supernatant in human fetal neurons.. One limitation of this study is the use of monocytoid and microglial cell lines. However, our experiments performed with primary adult human microglia corroborated data generated using the HMC3 microglia cell line. Also, similar to the results obtained with primary embryonic microglia [4], HMC3 secrete more CXCL10, CCL5, CCL2, and IL-6 in contact with HIV vector-transduced monocytoid cells than after contact with HIV particles alone. This finding as well as lack of neurotoxicity of microglia ...
Succinate and fumarate are four-carbon dicarboxylates that differ in the identity of their central bond (single or double). The oxidoreduction of these small molecules plays a central role in both aerobic and anaerobic respiration. During aerobic respiration, succinate is oxidized, donating two reducing equivalents, while in anaerobic respiration, fumarate is reduced, accepting two reducing equivalents. Two related integral membrane Complex II superfamily members catalyze these reactions, succinate:ubiquinone oxidoreductase (SQR) and fumarate:menaquinol oxidoreductase (QFR). The structure, function, and regulation of these integral-membrane enzymes are summarized here. The overall architecture of these Complex II enzymes has been found to consist of four subunits: two integral membrane subunits, and a soluble domain consisting of an iron-sulfur protein subunit, and a flavoprotein subunit. This architecture provides a scaffold that houses one active site in the membrane and another in the soluble milieu,
Butadiene, then, describes a compound built with a four-carbon chain containing two double bonds. A chemist would write this structure as CH₂=CHCH=CH₂, where the parallel lines indicate the double bonds. The final part of the name -- the prefix poly- -- tells you that there are many butadiene molecules strung together to form what chemists call a polymer. The polymerization process begins when an unpaired electron on one butadiene subunit steals an electron from an adjacent butadiene subunit, bonding the two together. This sequence of events occurs repeatedly until a long chain of molecules forms.. By itself, polybutadiene doesnt produce an effective material. It becomes gooey at high temperatures and brittle at low temperatures. To transform it into a resilient, stable rubber, Stingley borrowed a page from the lab manual of Charles Goodyear, who discovered that sulfur added to rubber made it flexible and resilient at any temperature. Goodyear called this vulcanization, and Stingley ...

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecules storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters. ...

A Cheaters Guide to Love. (1) Unlike the empirical articles assigned this week, A Cheaters Guide to Love by Junot Diaz doesnt seek to prove anything about self control. Its a piece of fiction-for all we know, Diaz could be making this caca up, couldnt he? Nonetheless, I found the short story to be a vivid and highly compelling depiction of human failures at self control. In particular, Diaz portrays the ineffective and often comical ways we attempt to maintain control against temptation, and to regain control after weve lost it. One way that we struggle to keep control in our hands, even though we know its slipping through our fingers, is by making promises. And of course, you swore you wouldnt do it, the narrator had promised his fiancé, it being cheat on her (61). You swore you wouldnt. You swore you wouldnt, he repeated. But of course, you did, and did so no less than fifty times! By repetitively asserting he wouldnt do what he was so tempted to do, the narrator was ...

  • The anaerobic, syntrophic bacterium Syntrophus aciditrophicus grown in pure culture produced 1.4 ± 0.24 mol of acetate and 0.16 ± 0.02 mol of cyclohexane carboxylate per mole of crotonate metabolized. (asm.org)
  • Cultures grown with unlabeled crotonate and [ 13 C]sodium bicarbonate formed [6- 13 C]cyclohexane carboxylate. (asm.org)
  • With [U- 13 C]crotonate, the m/z -15 ion of TMS-derivatized glutarate, 3-hydroxybutyrate, and acetoacetate each increased by +4 mass units, and the m/z -15 ion of TMS-derivatized pimelate, cyclohex-1-ene carboxylate, benzoate, and cyclohexane carboxylate each increased by +6 mass units. (asm.org)
  • With [ 13 C]sodium bicarbonate and unlabeled crotonate, the m/z -15 ion of TMS derivatives of glutarate, pimelate, cyclohex-1-ene carboxylate, benzoate, and cyclohexane carboxylate each increased by +1 mass unit, suggesting that carboxylation occurred after the synthesis of a four-carbon intermediate.

  • The data are consistent with a pathway for cyclohexane carboxylate formation involving the condensation of two-carbon units derived from crotonate degradation with CO 2 addition, rather than the use of the intact four-carbon skeleton of crotonate. (asm.org)
  • In this paper, we report the results of gas chromatography-mass spectrometry (GC-MS) and 13 C nuclear magnetic resonance spectroscopy ( 13 C-NMR) to elucidate the pathway for crotonate oxidation and cyclohexane carboxylate formation in S. aciditrophicus . (asm.org)
  • However, a number of fatty acid- and aromatic acid-degrading syntrophic bacteria grow in pure culture by fermenting crotonate ( 6 , 24 , 46 , 48 ). (asm.org)
  • To assess the role of crotonylation in kidney injury, crotonate was used to increase histone crotonylation in cultured tubular cells or in the kidneys in vivo . (biologists.org)
  • Systemic crotonate administration protected from experimental AKI, preventing the decrease in renal function and in kidney PGC-1α and sirtuin-3 levels as well as the increase in CCL2 expression. (biologists.org)
  • Analysis of four Karathane WD samples showed 16.8 - 17.7% 2,4- and 2,6-dinitro-octylphenyl crotonates, 2.4 - 3.1% dinitro- octylphenols and 0.19 - 0.21% mononitro-octylphenols giving a total active ingredient content of 19.4 - 20.7%, which is in good agreement with the declared content.
