Kinetics of cell lysis, dye uptake and permeability changes in cells expressing the rat P2X7 receptor. (1/308)

1. Extracellular ATP acting on P2X7 receptors opens a channel permeable to small cations, creates an access pathway for the entry of larger molecular weight dyes, and causes cell death. We used whole-cell recording and fluorescence microscopy to measure the time courses of ionic currents, uptake of the propidium dye YO-PRO-1, and membrane disruption, in human embryonic kidney (HEK293) cells expressing the rat P2X7 receptor. 2. The ATP analogue 2', 3'-O-(benzoyl-4-benzoyl)-ATP (30 microM) induced membrane blebbing within 30-40 s of sustained application; this was 5-10 times slower when extracellular sodium was replaced by larger cations. 3. Fluorescence of YO-PRO-1 was detectable within 3 s, and the uptake reached a steady rate within 10-20 s; YO-PRO-1 uptake was greatly enhanced by removing extracellular sodium. 4. Electrophysiological measurements of current reversal potentials with intracellular sodium and extracellular cations of different sizes showed that the ionic channel progressively t'2+LE0i%-i"dilated during 10-20 s to a diameter greater than 1 nm (10 A). With short agonist applications (3-5 s) the pore dilatation and YO-PRO-1 uptake were reversible and repeatable. 5. Polyethylene glycols having molecular weights >= 5000 blocked the increase in cation permeability, YO-PRO-1 uptake and membrane blebbing. 6. We conclude that maximum P2X7 receptor activation causes an exponential dilatation of the ion channel with a time constant of 25 s to a final diameter of 3-5 nm from an initial minimum pore diameter of 0.8 nm.  (+info)

Protamine-induced condensation and decondensation of the same DNA molecule. (2/308)

The DNA in sperm and certain viruses is condensed by arginine-rich proteins into toroidal subunits, a form of packaging that inactivates their entire genome. Individual DNA molecules were manipulated with an optical trap to examine the kinetics of torus formation induced by the binding of protamine and a subset of its DNA binding domain, Arg6. Condensation and decondensation experiments with lambda-phage DNA show that toroid formation and stability are influenced by the number of arginine-rich anchoring domains in protamine. The results explain why protamines contain so much arginine and suggest that these proteins must be actively removed from sperm chromatin after fertilization.  (+info)

Is hydroxylamine-induced cytotoxicity a valid marker for hypersensitivity reactions to sulfamethoxazole in human immunodeficiency virus-infected individuals? (3/308)

Hypersensitivity (HS) reactions to sulfonamides and sulfones continue to limit their use in human immunodeficiency virus (HIV)-infected individuals. In vitro cytotoxicity of hydroxylamine metabolites toward peripheral blood mononuclear cells (PBMCs) has been proposed as a marker for these HS reactions. To test the validity of this in vitro system, we determined the selective susceptibility of PBMCs from HIV-infected patients to the cytotoxic effects of hydroxylamine metabolites of sulfamethoxazole (SMX) and dapsone (DDS). Concentration-cytotoxic response data were collected using PBMCs from 12 sulfa-HS (10 SMX-HS and 2 SMX/DDS-HS) and 10 sulfa-tolerant HIV-infected individuals. Although sulfamethoxazole hydroxylamine (SMX-NOH) and dapsone hydroxylamine (DDS-NOH) both caused concentration-dependent increases in cell death, DDS-NOH was significantly more potent in each subject (P <.0001). A comparison of a variety of mean data for sulfa-HS and -tolerant patient populations failed to demonstrate the increased susceptibility of PBMCs from HS patients, noted by others, to either SMX-NOH or DDS-NOH. Moreover, any trend toward an increased susceptibility of PBMCs from HS patients was eliminated when adjusted for control cell death. PBMCs from sulfa-HS patients showed significantly greater susceptibility to the stress of short term in vitro incubation (P <. 02). Mean (S.D.) vehicle control cell death values were 24.1% (7.6%) for HS patients and 17.1% (4.4%) for tolerant patients. No significant correlation was observed between hydroxylamine-induced or control cell death and any of the recorded clinical parameters. Although several potential reasons are proposed to explain the disparity with past investigations, the data suggest that in vitro cytotoxicity is not a valid marker for HS reactions in HIV-infected individuals using currently accepted experimental procedures.  (+info)

Apparent species differences in the kinetic properties of P2X(7) receptors. (4/308)

1. Apparent species differences in the responses of recombinant P2X(7) receptors to repeated application of 2'- and 3'-O-(4-benzoylbenzoyl)-ATP (BzATP) have been investigated. 2. Repeated application of 100 microM BzATP resulted in a progressive increase in current magnitude (current growth) at mouse and human, but not rat P2X(7) receptors. 3. Current growth was thought to reflect progressive dilation of the P2X(7) ion-channel to a pore permeable to large molecules (MW<900), suggesting that channel dilation was not occurring at the rat P2X(7) receptor. However, 100 microM BzATP produced a rapid influx of YO-PRO-1 (MW375) in cells expressing rat or human P2X(7) receptors. 4. There were, however, species differences in agonist potency such that 100 microM BzATP was a supra-maximal concentration at rat, but not human or mouse, P2X(7) receptors. Importantly, when sub-maximal concentrations of BzATP or ATP were examined, current growth occurred at rat P2X(7) receptors. 5. The rate of current growth and YO-PRO-1 accumulation increased with agonist concentration and appeared more rapid at rat and human, than at mouse P2X(7) receptors. 6. The potency of BzATP and ATP was 1.5 - 10 fold lower in naive cells than in cells repeatedly exposed to ATP. 7. This study demonstrates that current growth occurs at mouse, rat and human P2X(7) receptors but only when using sub-maximal concentrations of agonist. Previously, current growth was thought to reflect the progressive increase in pore diameter of the P2X(7) receptor ion channel, however, the results of this study suggest a progressive increase in agonist potency may also contribute.  (+info)

Antagonist effects on human P2X(7) receptor-mediated cellular accumulation of YO-PRO-1. (5/308)

We have examined the interaction of P2 antagonists with the human P2X(7) receptor by studying their effect on 2' and 3'-O-benzoyl-benzoyl-ATP (DbATP) stimulated cellular accumulation of the fluorescent, DNA binding dye, YO-PRO-1 (MW=375Da). In suspensions of HEK293 cells expressing human recombinant P2X(7) receptors, DbATP produced time and concentration-dependent increases in YO-PRO-1 fluorescence. This response presumably reflects YO-PRO-1 entry through P2X(7) receptor channels and binding to nucleic acids. When studies were performed in a NaCl-free, sucrose-containing buffer, full concentration-effect curves to DbATP could be constructed. The P2 antagonists, pyridoxalphosphate-6-azophenyl-2', 4'-disulphonic acid (PPADS) and periodate oxidized ATP (oATP), reduced the potency of DbATP and decreased its maximum response. 1-[N,O-bis(1, 5-isoquinolinesulphonyl)-N-methyl-L-tyrosyl]-4-phenylpiperazine (KN62) and its analogue, KN04, reduced the potency of DbATP. Schild slopes for KN62 and KN04 were shallow and exhibited a plateau at concentrations of compound greater than 1 microM, indicating that these compounds were not competitive antagonists. Calmidazolium and a monoclonal antibody to human P2X(7) receptors attenuated DbATP-stimulated YO-PRO-1 accumulation but they were not competitive antagonists and only produced 2 - 3 fold decreases in the potency of DbATP. The effects of PPADS and KN62 were partially reversible whereas those of oATP were not. PPADS protected cells against the irreversible antagonist effects of oATP suggesting a common site of action. In contrast KN62 was not effective suggesting that it may bind at a different site to oATP and PPADS. This study has demonstrated that P2X(7) receptor function can be quantified by measuring DbATP stimulated YO-PRO-1 accumulation and has provided additional information about the interaction of P2 receptor antagonists with the human P2X(7) receptor.  (+info)

Brilliant blue G selectively blocks ATP-gated rat P2X(7) receptors. (6/308)

There are few antagonists selective for subtypes of the several P2X receptors, but these are needed to identify the receptors expressed on native cells and tissues. In particular, P2X(4) and P2X(7) receptor subunits are colocalized on immune, epithelial, and exocrine gland cells, but both are relatively insensitive to suramin and pyridoxal-5-phosphate-6-azo-2',4'-disulfonic acid derivative. In this article, we show that Coomassie Brilliant Blue G selectively inhibits P2X(7) receptors with nanomolar affinity. We measured currents in response to P2X receptor activation in HEK293 cells heterologously expressing human or rat P2X(1), P2X(2), P2X(3), P2X(2/3), P2X(4), P2X(1/5), and P2X(7) receptors. Brilliant Blue G produced a noncompetitive inhibition of rat and human P2X(7) receptors with IC(50) values of 10 and 200 nM, respectively. IC(50) values for inhibition of the other receptors ranged from 2 to >30 microM; the rat and human P2X(4) receptors showed IC(50) values of >10 and 3.2 microM. Coomassie Blue G also blocked YO-PRO1 uptake and membrane blebbing, which are uniquely associated with activation of P2X(7) receptors. Thus, Brilliant Blue G is at least 1000-fold more potent at rat P2X(7) receptors than at rat P2X(4) receptors.  (+info)

Gene transfer by cationic surfactants is essentially limited by the trapping of the surfactant/DNA complexes onto the cell membrane: a fluorescence investigation. (7/308)

The interaction between complexes of plasmid DNA with cetyltrimethylammonium bromide (CTAB) and L929 fibroblasts was first examined using confocal microscopy. The complexes labeled with the DNA intercalator, YOYO-1, were found to be trapped onto the external face of the plasma membrane; a feature that may constitute a major limiting step in transfection. Moreover, since no cytotoxic effect appeared in these conditions, we further inferred that the CTAB molecules remained bound to the DNA. The interaction of the complexes with the membranes was best modeled with neutral vesicles. From anisotropy thermotropic curves of DPHpPC-labeled vesicles and fluorescence resonance energy transfer measurements between these vesicles and YOYO-labeled complexes, we evidenced that the binding of the complexes to the vesicle surface opened the micelle-like domains and unwound DNA. However, DNA was not released but remained stably bound via electrostatic interactions to the CTAB molecules incorporated in the external liposome leaflet. Consequently, the large diameter of the unwound plasmid DNA is likely the major factor that precludes its internalization into the cells by endocytosis. In contrast, anionic vesicles that mimic the cytoplasmic facing monolayer of the plasma membrane rapidly released DNA from the complex. This may explain the previously reported high transfection efficiency of DNA complexed with liposomes composed of neutral lipids and cationic surfactants, since the latter may destabilize the endosomal membrane and induce the release of DNA in the cytoplasm.  (+info)

Lipoic acid-derived amphiphiles for redox-controlled DNA delivery. (8/308)

BACKGROUND: Intracellular release of free DNA from the vector complex is one of the critical steps limiting the efficiency of non-viral gene delivery. The complex should be stable enough to prevent DNA degradation but it should be destabilized inside the cell to allow DNA release and transcription. Destabilization and degradation of synthetic vectors is also required to reduce their cytotoxicity and augment the life-time of transfected cells. RESULTS: Here we describe new cationic amphiphiles made from the natural pro-vitamin, lipoic acid, that reversibly binds and releases DNA, depending on the redox state of the lipoate moieties. In the oxidized state these amphiphiles condense DNA into homogeneous spherical particles, which, upon reduction, swell into DNA toroids with subsequent release of free DNA. Complex reduction and DNA release can be induced by various thiols as well as enzymatically, by thioredoxin reductase. Transfection with amphiphile-DNA complexes in vitro shows a several fold increase of transgene expression compared with DOTAP, and can be further augmented by attachment of the nucleus-targeting peptide to the amphiphile. The increase of transfection efficiency results from GSH- and NAD(P)H-dependent complex reduction and release of free DNA inside the cells. CONCLUSIONS: The present work demonstrates the principle of a redox-controlled gene delivery system that uses the reversibility of thiol-disulfide exchange reaction. Our data suggest that the efficiency of synthetic vectors can be augmented by their controlled destabilization inside the cells. Being formed from the natural non-toxic compound lipoic acid, these cationic amphiphiles provide a new promising class of synthetic vectors for gene delivery.  (+info)

The influence of peptide sequence and Leu chirality in linear and cyclic peptides containing 3-[2-(9-anthryl)benzoxazol-5-yl]alanine on interaction with β-cyclodextrin were studied using fluorescence and NMR spectroscopy. The analysis of enthalpy-entropy compensation effect (α=1.05±0.02 and TΔS00=15.1±0.5 kJ mol−1) indicates that the entropic contribution connected with the solvent reorganization is the major factor governing the peptides-β-cyclodextrin complexation. Moreover, spatial orientation of guest-host molecule depends more than association constant on Leu residue configuration. However, the cyclization of the peptide chain substantially decrease the association constant with β-CD.

Plants play an essential part in global carbon fixing through photosynthesis and are the primary food and energy source for humans. Understanding them thoroughly is therefore of highest interest for humanity. Advances in DNA and RNA sequencing and in protein and metabolite analysis allow the systematic description of plant composition at the molecular level. With imaging mass spectrometry, we can now add a spatial level, typically in the micrometer-to-centimeter range, to their compositions, essential for a detailed molecular understanding. Here we present an LC-MS based approach for 3D plant imaging, which is scalable and allows the analysis of entire plants. We applied this approach in a case study to pepper and tomato plants. Together with MS/MS spectra library matching and spectral networking, this non-targeted workflow provides the highest sensitivity and selectivity for the molecular annotations and imaging of plants, laying the foundation for studies of plant metabolism and plant-environment
DESCRIPTION (provided by applicant): This project aims to demonstrate that the evolution of plant biosynthetic pathways can be accelerated and driven to favor the synthesis of ligands which interact with a specific human target protein. This is achieved bysubjecting mutant plant cells to selection pressures favoring the survival of mutants with the phenotype of interest. As an example, this approach will be used to optimize pharmacological activity in Lobelia cardinalis, which inhibits the human dopamine transporter (hDAT), putatively by its ability to synthesize the complex alkaloid, lobinaline. A stable transgenic line of L. cardinalis plant cells expressing the hDAT has been established. These cells show increased sensitivity to toxins transported into the cell by the hDAT, including the neurotoxin MPP+. A large, genetically diverse, population of gain-of-function mutants expressing the hDAT has now been generated, and selected on medium containing 100uM MPP+, which kills the vast majority of ...
Frank came across a similar situation in his research with curcumin, a secondary plant metabolite of turmeric, an ingredient used in curry that also has health benefits. "We found that 99.9 percent of all curcumin is metabolised in the liver. Researchers are currently investigating whether metabolites that circulate in the blood have an effect. We also want to study this in prenylflavonoids," says Frank. However, these projects are currently of minor importance for him. Frank is mainly interested in finding a way of improving the absorption rate of secondary plant metabolites and hence their potential health benefits.. Frank works with AQUANOVA AG from Darmstadt and uses the companys micelle technology for his research. AQUANOVA produces so-called product micelles from complex, food-grade carrier substances that have a lipophilic component (tail) on the inside and a hydrophilic component on the outside. The micelles are formulated and manufactured in such a way that they are stable in the ...

The commonly used fluorescent dye YOYO-1 (YOYO) has, using bulk techniques, been demonstrated to stain DNA heterogeneously at substoichiometric concentrations. We here, using nanofluidic channels and fluorescence microscopy, investigate the heterogeneous staining on the single DNA molecule level and demonstrate that the dye distribution is continuous. The equilibration of YOYO on DNA is extremely slow but can be accelerated by increasing the ionic strength and/or the temperature. Furthermore, we demonstrate how to use the heterogeneous staining as a tool for detailed and time-efficient studies of how fluorescent dyes affect the physical properties of DNA. We show that the relative increase in extension of DNA with increasing amount of YOYO bound is higher at low ionic strengths and also extrapolate the extension of native DNA. Our study reveals important information on how YOYO affects the physical properties of DNA, but it also has broader applications. First, it reveals how cationic intercalators,

Orexin-A (hypocretin-1) and orexin-B (hypocretin-2) are hypothalamic neuropeptides that play key roles in the regulation of wakefulness, feeding, reward, autonomic functions and energy homeostasis. To control these functions indispensable for survival, orexin-expressing neurones integrate peripheral metabolic signals, interact with many types of neurones in the brain and modulate their activities via the activation of orexin-1 receptor or orexin-2 receptor. In addition, a new functional role of orexin is emerging in the regulation of insulin and leptin sensitivities responsible for whole-body glucose metabolism. Recent evidence indicates that orexin efficiently protects against the development of peripheral insulin resistance induced by ageing or high-fat feeding in mice. In particular, the orexin receptor-2 signalling appears to confer resistance to diet-induced obesity and insulin insensitivity by improving leptin sensitivity. In fact, the expression of orexin gene is known to be ...

I dye yarn for a living fabric too but Mx dyes. I use a combination of Lanaset Dharma and some Jacquard. The Jacquard colors I use I always mix and often with Dharma or other Acid dyes. I love them. The colors are true weighed mixes are so close that I cannot see a difference in the colors after dyeing and drying. I cannot duplicate some of the basic colors Jacquard carries because the names are similar the colors are not. Jacquard Pink is a great example. It does not look like anyone elses Magenta or Fuschia. It stands alone. Behaves itself with vinegar (used with yarns with Stellina in them) and Citric Acid. I use the Cherry Silver Golden Ochre Aztec Gold and Sky Blue. I do not interchange the Jacquard colors with any other colors when a formula calls for them. If I dont have them on hand I do not dye that colorway. A really good mix is the Dharma Acid Sun Yellow with the Jacquard Aztec Gold overlaid with some other colors. I am happy with Jacquard Acid Dyes and even though I no longer buy ...

The aim of this project is to understand the molecular mechanisms of plant flavonoids in nitrogen fixing symbioses of legumes. Flavonoids are a class of secondary plant metabolites that have a range of functions in signalling, defence, and gene and protein regulation. We are investigating how certain plant flavonoids control root symbioses as regulators of auxin transport in the plant and in the signalling between plants and microbes. We are using RNA interference, gene profiling and fluorescence microscopy to manipulate the flavonoid pathway and unravel their targets in plants.
1. Introduction In the aerobic environment, the most dangerous by product are the species of reactive oxygen. The role of antioxidants is to detoxify reactive oxygen intermediates (ROI) in the body. Over the past several years, nutritional antioxidants have attracted considerable interest in the popular press as potential treatment for a wide variety of disease states, including cancer and other causes e.g. cancer, chronic inflammatory diseases and aging (Delany L. 1993).. Naturally occurring inhibitors of oxidation in food generally originate from plant-based materials. The active components, namely phenolics and polyphenolics, including tocopherols, are secondary plant metabolites and are first derived from phenylalanine and in certain cases and in some plants from tyrosine. The resultant phenylpropanoids may then undergo further transformation to yield benzoic acid derivatives as well as flavonoids, isoflavons, and other complex polyphenols. Thus, natural food phenolics are present as a ...

2012) in varying importance but not investigated in humans so far to the best of our knowledge. However, due to an average urinary excretion rate of 72% ( Turner et al., 2010) it can be derived that excretion via feces is not the main route in humans. Two recent in vitro studies examined the metabolism of DON and its plant metabolite DON-3-Glc by the human fecal microbiota and found that DON can be. released from its glycosylated form ( DallErta et al., 2013 and Gratz et al., 2013). Zearalenone metabolism was studied in various animals, especially Selleck NVP-BGJ398 in pigs as they are particularly sensitive to associated adverse effects such as decreased fertility. Biotransformation takes place in two major pathways: Hydroxylation forms the phase-I-metabolites α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL), while conjugation of ZEN GW3965 manufacturer and its reduced forms with glucuronic acid and sulfate leads to the formation of typical phase-II-conjugation products.

Drug addiction is a chronic illness characterized by high rates of relapse. Relapse to drug use can be triggered by re-exposure to drug-associated cues, stressful events, or the drug itself after a period of abstinence. Pharmacological intervention to reduce the impact of relapse-instigating factors offers a promising target for addiction treatment. Growing evidence has implicated an important role of the orexin/hypocretin system in drug reward and drug-seeking, including animal models of relapse. Here, we review the evidence for the role of orexins in modulating reward and drug-seeking in animal models of addiction and the potential for orexin receptors as specific targets for anti-relapse medication approaches.

Disrupted sleep is associated with increased risk of type 2 diabetes. Central actions of orexin, mediated by orexin-1 and orexin-2 receptors, play a crucial role in the maintenance of wakefulness; accordingly, excessive activation of the orexin system causes insomnia. Resting-phase administration of dual orexin receptor antagonist (DORA) has been shown to improve sleep abnormalities and glucose intolerance in type 2 diabetic db/db mice, although the mechanism remains unknown. In the present study, to investigate the presence of functional link between sleep and glucose metabolism, the influences of orexin antagonists with or without sleep-promoting effects were compared on glucose metabolism in diabetic mice. In db/db mice, 2-SORA-MK1064 (an orexin-2 receptor antagonist) and DORA-12 (a DORA) acutely improved non-rapid eye movement sleep, whereas 1-SORA-1 (an orexin-1 receptor antagonist) had no effect. Chronic resting-phase administration of these drugs improved glucose intolerance, without ...

In a situation where technology allows for the simultaneous measurement of numerous parameters of a single sperm cell, it becomes crucial to choose those parameters which may be useful in estimating in vivo fertility. Sperm membrane destabilization is believed to occur during chilling of semen, although its effect on the post-thaw (PT) fertility of the spermatozoa has not yet been fully assessed. For this reason, we tested a new combination of fluorophores, Merocyanine 540 (M540)/Yo-Pro 1/Hoechst 33342 (H33342), to detect sperm plasma membrane destabilization in bull spermatozoa conventionally processed for artificial insemination (AI). The samples were tested by flow cytometry (FC), both immediately PT and following an in vitro swimup (SU) technique, and results were thereafter compared with conventional sperm quality Measurements (of concentration, motility, morphology, and membrane integrity), including in vivo fertility. Semen samples from six Estonian Holstein (EHF) AI bulls, frozen when ...
In tropical countries many indigenous communities maintain traditional medicine practices. Efforts have been made to identify and elucidate specific bioactive plant metabolites that exhibit significant physiological and pharmacological effects. Advances have been made to identify virulence factors in pathogenic microbes and their novel inhibitors from natural products, due to emerging resistance of pathogens to frequently used synthetic medicines. Phytochemical studies of plant species of the Rutaceae family have led to isolation of a variety of compounds; alkaloids, flavonoids, coumarins and terpenoids exhibiting significant bioactivities. In this study, extracts from the plant species of Calodendrum capense Thunb. (Rutaceae) were subjected to isolation and phytochemical screening of metabolites. The organic crude extracts of leaves, stem bark, fruit pericarp and seeds of this plant species were sequentially extracted starting with hexane, DCM, EtOAc and MeOH. Antimicrobial assay was carried ...
Steroidal saponins are plant metabolites with a broad range of biological activities (Hostettmann & Marston, 1995). They are composed by a glycoside and a triterpene or steroidal fragment. Hydrolysis of saponins provides a glycoside free portion termed sapogenin which can be of the cholestane, furostane or spirostane type. The spirostane sapogenins also display economic importance due to their application in the synthesis of biologically active compounds such as insect hormones (Lee et al., 1976) cephalostatins and ritterazines (Lee et al., 2009, Phillips & Shair, 2007 and Pettit et al., 1988). In previous studies we reported the preparation of epoxycholestane derivatives as useful intermediates in the synthesis of norbrassinosteroid analogues (Rincón et al., 2006), in continuation with our studies we report herein on the synthesis and crystal structure of the title compound, (I), obtained by treatment of the previously reported ...
Chemical ecology began with the study of plant-insect interactions. In the nineteenth century, biologists began to realize the profound importance of plant chemistry in determining herbivore choice. Given that plants are the primary source of food in terrestrial ecosystems, the role of plant metabolites in herbivore choice and performance translates to a role in structuring ecological communities. This work describes natural variation in volatile and non-volatile herbivore-induced metabolites in the native tobacco /Nicotiana attenuata/, and experiments to test the defensive functions of some of these metabolites in nature. The variation described includes natural variation among accessions in herbivore-induced signaling cascades and metabolite production, as well as complex metabolic variation in a class of terpenoid specialized metabolites, the 17-hydroxygeranyllinalool diterpene glycosides (HGL-DTGs), in response to herbivore-induced signaling. I dissect the contribution of herbivore-induced ...
