Glioblastomas are largely unresponsive to all available treatments and there is therefore an urgent need for novel therapeutics. Here we have probed the antineoplastic effects of a bacterial protein toxin, the cytotoxic necrotizing factor 1 (CNF1), in the syngenic GL261 glioma cell model. CNF1 produces a long-lasting activation of Rho GTPases, with consequent blockade of cytodieresis in proliferating cells and promotion of neuron health and plasticity. We have tested the antiproliferative effects of CNF1 on GL261 cells and human glioma cells obtained from surgical specimens. For the in vivo experiments, we injected GL261 cells into the adult mouse visual cortex, and five days later we administered either a single intracerebral dose of CNF1 or vehicle. To compare CNF1 with a canonical antitumoral drug, we infused temozolomide (TMZ) via minipumps for 1 week in an additional animal group. In culture, CNF1 was very effective in blocking proliferation of GL261 cells, leading them to multinucleation,

We recently found that a small population of these macrophages is spontaneously and temporally refractory to LeTx-induced cytotoxicity. Analysis of genome-wide transcripts of a resistant clone before and after regaining LeTx sensitivity revealed that a reduction of two closely related mitochondrial proteins, Bcl-2/adenovirus E1B 19-kDa interacting protein 3 (Bnip3) and Bnip3-like (Bnip3L), correlates with LeTx resistance. Down-regulation of Bnip3 and Bnip3L was also found in toxin-induced resistance whereby sublethal doses of LeTx induce resistance to subsequent exposure to cytolytic toxin doses. The role of Bnip3 and Bnip3L in LeTx-induced ...

In this paper, we observed the effects of mutating each of the six anionic residues lining the interior of the anthrax toxin channel to serines. Before discussing the effects of these mutations on cation selectivity, we must first address the possibility that streaming potentials and/or polarization effects (dilution potentials) may have skewed our results. By polarization effects, we mean that as a consequence of osmotic water flow across the membrane from the trans to the cis solution caused by the higher KCl concentration in the cis compartment, the KCl concentration at the cis membrane-solution interface is reduced, and at the trans membrane-solution interface it is elevated. Consequently, the actual acis/atrans across the membrane is less than the bulk acis/atrans, thereby artificially reducing the magnitude of Erev. To check for polarization effects, we performed cation selectivity experiments (not depicted) with valinomycin (which is ideally selective for potassium) at both [KCl]trans = ...
Mass spectrometry has recently become a powerful technique for bacterial identification. Mass spectrometry approaches generally rely upon introduction of the bacteria into a matrix-assisted laser-desorption time-of-flight (MALDI-TOF) mass spectrometer with mass spectrometric recognition of proteins specific to that organism that form a reliable fingerprint. With some bacteria, such as Bacillus anthracis and Clostridium botulinum, the health threat posed by these organisms is not the organism itself, but rather the protein toxins produced by the organisms. One such example is botulinum neurotoxin (BoNT), a potent neurotoxin produced by C. botulinum. There are seven known serotypes of BoNT, A-G, and many of the serotypes can be further differentiated into toxin variants, which are up to 99.9% identical in some cases. Mass spectrometric proteomic techniques have been established to differentiate the serotype or toxin variant of BoNT produced by varied strains of C. botulinum. Detection of potent ...

ABSTRACTCytotoxic Necrotizing Factor 1 (CNF1) is a protein toxin from Escherichia coli that constitutively activates the Rho, Rac and Cdc42 GTPases.

Blood clots play an unexpected role in protecting the body from the deadly effects of bacteria by absorbing bacterial toxins, researchers at the University of California, Davis, have found. The research was published Dec. 2 in the journal PLoS ONE. Â Its a significant addition to the short list of defenses that animals use to protect themselves against toxin-induced sepsis, says Peter Armstrong, professor of molecular and cellular biology at UC Davis and senior author on the paper. Â Even with modern antibiotics, septic shock from bacterial infections afflicts about 300,000 people a year in the U.S., with a mortality rate of 30 to 50 percent. Septic shock is caused by Gram-negative bacteria, which release a toxin called lipopolysaccharide or endotoxin. In small amounts, lipopolysaccharide triggers inflammation. When infections with these bacteria get out of hand, lipopolysaccharide courses through the bloodstream, causing catastrophic damage to organs and tissues. Â These toxins cause disease

Clostridium perfringens epsilon toxin (ETX) rapidly kills MDCK II cells at 37°C, but not 4°C. The current study shows that, in MDCK II cells, ETX binds and forms an oligomeric complex equally well at 37°C and 4°C but only forms a pore at 37°C. However, the complex formed in MDCK cells treated with ETX at 4°C has the potential to form an active pore, since shifting those cells to 37°C results in rapid cytotoxicity. Those results suggested that the block in pore formation at 4°C involves temperature-related trapping of ETX in a prepore intermediate on the MDCK II cell plasma membrane surface. Evidence supporting this hypothesis was obtained when the ETX complex in MDCK II cells was shown to be more susceptible to pronase degradation when formed at 4°C vs. 37°C; this result is consistent with ETX complex formed at 4°C remaining present in an exposed prepore on the membrane surface, while the ETX prepore complex formed at 37°C is unaccessible to pronase because it has inserted into the ...

However, the application of this technology is limited by the poor response of the immune system to non-particulate, subunit vaccines. Co-delivery of therapeutic proteins with carrier proteins could increase the effectiveness of the antigen. This paper reports the ability of transgenic Arabidopsis thaliana plants to produce a fusion protein consisting of the B subunit of the Escherichia coli heat-labile enterotoxin and a 6 kDa tuberculosis antigen, the early secretory antigenic target ESAT-6. Both components of the fusion protein were detected ...
Pulpy kidney disease is an important fatal enterotoxaemia of sheep and occasionally other ruminants. Although history, clinical signs, post mortem picture, histopathological findings and demonstration of glucosuria are helpful in diagnosing the disease, the demonstration of Clostridium perfringens epsilon toxin in the small intestine is a useful additional aid to diagnosis. Methods used to assay the toxin in the gut must be specific and sensitive, as the toxin is highly potent and small amounts can be significant in nonimmune animals, as little as 0.3 ng of activated toxin being sufficient to kill a mouse. The biological test is therefore a sensitive method for measuring toxin. However, unless small intestine contents are titrated in a number of mice it is not a quantitative method and is currently viewed with disfavour on humanitarian grounds. Although other tests have been used, for example the reversed phase passive haemagglutination, radial immunodiffusion and counter immunoelectrophoresis ...
Cytotoxic necrotizing factor type 2 (CNF2) produced by Escherichia coli strains isolated from intestinal and extraintestinal infections is a dermonecrotic toxin of 110 kDa. We cloned the CNF2 gene from a large plasmid carried by an Escherichia coli strain isolated from a lamb with septicemia. Hydropathy analysis of the deduced amino acid sequence revealed a largely hydrophilic protein with two potential hydrophobic transmembrane domains. The N-terminal half of CNF2 showed striking homology (27% identity and 80% conserved residues) to the N-terminal portion of Pasteurella multocida toxin. Methylamine protection experiments and immunofluorescence studies suggested that CNF2 enters the cytosol of the target cell through an acidic compartment and induces the reorganization of actin into stress fibers. Since the formation of stress fibers in eukaryotic cells involves Rho proteins, we radiolabeled these small GTP-binding proteins from CNF2-treated and control cells with a Rho-specific ...
Escherichia coli heat-labile enterotoxin, molecular model. This is one of several proteins produced by pathogenic E. coli bacteria in the intestines. Unlike the heat-stable enterotoxin, this one is inactivated at high temperatures. The toxin causes diarrhoea and can be fatal in severe cases. This protein consists of three subunits with a total of seven chains and a total of 329 amino acids. - Stock Image C025/1673
Clostridium difficile toxin B is a toxin produced by the bacteria Clostridium difficile. C. difficile produces two major kinds of toxins that are very potent and lethal; an enterotoxin (Toxin A) and a cytotoxin (Toxin B, this protein). Toxin B (TcdB) is a cytotoxin that has a molecular weight of 270 kDa and an isoelectric point, pl, of 4.1. Toxin B has four different structural domains: catalytic, cysteine protease, translocation, and receptor binding. The N-terminal glucosyltransferase catalytic domain includes amino acid residues 1-544 while the cysteine protease domain includes residues 545-801. Additionally, the translocation region incorporates amino acid residues from 802 to 1664 while the receptor binding region is part of the C-terminal region and includes amino acid residues from 1665 to 2366. The glycosylation activity of toxin B occurs in the N-terminal catalytic region (residues 1-544). This region glycosylates substrates independent of any cytotoxic activity. However, a small ...
OBJECTIVE: Neurotrophins and extracellular matrix (ECM) molecules are involved in neurite guidance during the development of spiral ganglion (SG) neurons. Several intracellular signaling molecules can be activated by ECMs and neurotrophins via their cognate receptors. In other systems these include the Rho small GTPases, which influence reorganization of the actin cytoskeleton that is required for axon growth. The aim of this study was to determine whether neurotrophin-3 (NT-3)-mediated SG neurite outgrowth on laminin-1 (LN) is dependent on the activation of the small GTPases Rho/Rac/Cdc42. MATERIAL AND METHODS: SG explants from postnatal day 4 rats were cultured on LN with and without NT-3 and increasing concentrations of Clostridium difficile Toxin B, an inhibitor of Rho GTPases. After fixation and immunocytochemical labeling, neurite growth was evaluated. RESULTS: Treatment with C. difficile Toxin B without NT-3 led to a dose-dependent decrease in the length and number of processes on LN. In ...
DESCRIPTION (provided by applicant): C. perfringens epsilon-toxin (ETX) is a potential biological weapon included in the list of category B priority agents. The overall goal of this proposal is to identify and perform in vivo testing of new inhibitors of E TX using a novel approach for the inactivation of pore-forming toxins developed at Innovative Biologics, Inc. It is based on the blocking of the target pore with molecules having the same symmetry as the pore itself. Results from our SBIR Phase I project d emonstrated that beta-cyclodextrin derivatives designed to block the transmembrane channel formed by epsilon-toxin can inhibit its cytotoxicity at low micromolar concentrations. Based on the successful completion of this feasibility study, we propose to de sign, synthesize and screen a library of beta-cyclodextrin derivatives for inhibitors of epsilon-toxins activity and test selected lead compounds in mice. The specific aims of this Phase II study are: (1) Optimize the assay for testing ...
A toxin-antitoxin system is a set of two or more closely linked genes that together encode both a protein poison and a corresponding antidote. When these systems are contained on plasmids - transferable genetic elements - they ensure that only the daughter cells that inherit the plasmid survive after cell division. If the plasmid is absent in a daughter cell, the unstable antitoxin is degraded and the stable toxic protein kills the new cell; this is known as post-segregational killing (PSK). Toxin-antitoxin systems are widely distributed in prokaryotes, and organisms often have them in multiple copies. Toxin-antitoxin systems are typically classified according to how the antitoxin neutralises the toxin. In a Type I toxin-antitoxin system, the translation of messenger RNA (mRNA) that encodes the toxin is inhibited by the binding of a small non-coding RNA antitoxin to the mRNA. The protein toxin in a type II system is inhibited post-translationally by the binding of another protein ...
Binary toxins are among the most potent bacterial protein toxins performing a cooperative mode of translocation and exhibit fatal enzymatic activities in eukaryotic cells. Anthrax and C2 toxin are the most prominent examples for the AB(7/8) type of toxins. The B subunits bind both host cell receptors and the enzymatic A polypeptides to trigger their internalization and translocation into the host cell cytosol. C2 toxin is composed of an actin ADP-ribosyltransferase (C2I) and C2II binding subunits. Anthrax toxin is composed of adenylate cyclase (EF) and MAPKK protease (LF) enzymatic components associated to protective antigen (PA) binding subunit. The binding and translocation components anthrax protective antigen (PA(63)) and C2II of C2 toxin share a sequence homology of about 35%, suggesting that they might substitute for each other. Here we show by conducting in vitro measurements that PA(63) binds C2I and that C2II can bind both EF and LF. Anthrax edema factor (EF) and lethal factor (LF) have ...

Cellular adaptation to microbial stresses has been demonstrated in several cell types. Macrophages (MФ) are sentinel immune cells fending off invading microbes. Anthrax lethal toxin (LeTx) is a key virulence factor released by Bacillus anthracis that causes rapid cell death, pyroptosis.

The Bacillus anthracis lethal factor (LF) is one component of a tripartite exotoxin partly responsible for persistent anthrax cytotoxicity after initial bacterial infection. Inhibitors of the zinc metalloproteinase have been investigated as potential therapeutic agents, but LF is a challenging target because inhibitors lack sufficient selectivity or possess poor pharmaceutical properties. These structural studies reveal an alternate conformation of the enzyme, induced upon binding of specific inhibitors, that opens a previously unobserved deep pocket termed S1* which might afford new opportunities to design selective inhibitors that target this subsite. ...

Cytolytic pore-forming toxins are important for the virulence of many disease-causing bacteria. How target cells molecularly respond to these toxins and whether or not they can mount a defense are poorly understood. By using microarrays, we demonstrate that the nematode Caenorhabditis elegans responds robustly to Cry5B, a member of the pore-forming Crystal toxin family made by Bacillus thuringiensis. This genomic response is distinct from that seen with a different stressor, the heavy metal cadmium. A p38 mitogen-activated protein kinase (MAPK) kinase and a c-Jun N-terminal-like MAPK are both transcriptionally up-regulated by Cry5B. Moreover, both MAPK pathways are functionally important because elimination of either leads to animals that are (i) hypersensitive to a low, chronic dose of toxin and (ii) hypersensitive to a high, brief dose of toxin such that the animal might naturally encounter in the wild. These results extend to mammalian cells because inhibition of p38 results in the hypersensitivity

TY - JOUR. T1 - Enteric bacterial toxins. T2 - Mechanisms of action and linkage to intestinal secretion. AU - Sears, Cynthia L.. AU - Kaper, James B.. PY - 1996/3/1. Y1 - 1996/3/1. N2 - A wide range of bacteria have been implicated as potential etiologies of diarrheal disease. Many of these organisms have been reported to produce one or more toxins postulated as important in the pathogenesis of the diarrhea resulting from infection with the organism. The primary goal of this review is to critically assess the linkage between the mechanism of action of toxins produced by human enteric pathogens and the stimulation of intestinal secretion. To accomplish this goal, the range of criteria used to demonstrate pathogenicity of an enteric bacterial toxin and potential mechanisms stimulating net intestinal secretion are reviewed. A detailed description of each enteric toxin is presented, and revised criteria are proposed for classification of enteric bacterial toxins. Throughout this review, emphasis has ...
From a structural perspective, the most compelling conclusion emerging from our findings is that the channels entire β-barrel stem region participates in the gating process. Absent a high resolution structure of the pore form of the anthrax channel in both the closed and open states, we cannot draw a detailed picture of the gating motions from our data. Nevertheless, we can gain some insight into the magnitude of the conformational changes that might occur during gating by considering the x-ray crystal structure of α-hemolysin, which likely shares structural features with the stem domain of the anthrax channel (Song et al., 1996; Benson et al., 1998; Nassi et al., 2002; Krantz et al., 2004; Nguyen, 2004).. The luminal diameter (Cα-Cα) of α-hemolysins β-barrel is ∼26 Å (accounting for sidechain volume, which is relevant to LF or EF translocation, yields a diameter of ∼19 Å [Krantz et al., 2004]), with residues of adjacent subunits being an average distance (Cβ-Cβ) of ∼11 Å from ...
Some pathogenic species of Clostridium employ the classic enzymatic AB binary protein toxins for poisoning cells. Clostridium perfringens, C. difficile, C. spiroforme, and C. botulinum all use similar binary toxins (iota toxin (Ia and Ib), CDT (CDTa and CDTb), CST (CSTa and CSTb), and C2 toxin (C2I and C2II), respectively). They consist of the enzymatic A component, an actin-specific ADP-ribosyltransferase and the B component that binds to the host cell and forms a membrane-spanning pore that functions as the translocation channel for each enzymatic component. The B component translocates the A component into the host cell via the membrane in the acidic endosome. In contrast, the Bacillus anthracis species uses a different binary toxin, which consists of two enzymatic proteins: the lethal (LF) and edema (EF) factors, and a protein translocation channel, PA. The PA heptameric pore structure was revealed to have extremely narrow φ-clamp passageway and a long membrane-spanning channel. ...

A BLAST search with the HI0659 protein sequence turns up homologs in only the same species. Some of these are annotated as members of an Xre-family toxin-antitoxin system (I think HI0660 is homologous to the toxin component, and HI0659 to the antitoxin component). HI0660 is also tagged as a member of the Gp49 superfamily (also phage proteins I think). Xre family repressors are known to perform a variety of regulatory functions unrelated to toxin-antitoxin systems (ref). The same paper suggests that the Tad toxin components might be mRNA-cleaving ribonucleases. Maybe thats what HI0660 does, and HI0659 is a repressor that prevents it from acting. If so, and if sxy mRNA was HI0660s target, then the mutant phenotypes would make sense. ...

It is difficult to correlate in vitro toxin concentration with in vivo exposure, however, the concentration of toxin used in both models are similar as 2.3 mg DON/kg of feed corresponds to 7.7 μM ( Sergent et al., 2006; Pinton et al., 2009). It is interesting to observe that in both models, there is a good correlation in the increase of expression of phosphorylated MAPK. The extent of MAPK activation, lower in samples obtained from the in vivo experiment than in explants, could be explained by the mode of exposure to the toxin, in the culture medium. or in ingested feed. A significant increase was observed only for ERK and p38. Following the same signaling arrangement, each individual MAPK pathway responds PF-02341066 in vivo to specific stimuli and then regulates their specific substrates ( Cui et al., 2007), which can explain the selective activation of MAPK. JNK and ERK are involved in regulation of both cell survival and death depending on cell types and stimulus, whereas p38 can promote ...
