Selective killing of CD8+ cells with a 'memory' phenotype (CD62Llo) by the N-acetyl-D-galactosamine-specific lectin from Viscum album L. (1/150)

As reported previously by our group, among the toxic proteins from Viscum album L. only the mistletoe lectins (MLs) induce the apoptotic killing pathway in human lymphocytes. Although one may expect a homogenous distribution of carbohydrate domains on cell surface receptors for the carbohydrate binding B chains of the toxic protein, the sensitivity of cells to these B chains obviously differ. Here we report a selective killing of CD8+ CD62Llo cells from healthy individuals by the galNAc-specific ML III (and RCA60, which binds to gal and galNAc), while the gal-specific ML I was less effective. This selective killing is not sufficiently explained by protein synthesis inhibition alone, since this subset was not affected by other ribosome inhibiting proteins such as the lectin from Ricinus communis (RCA120), lectin from Abrus precatorus (APA), abrin A, and inhibitors of RNA, DNA and/or protein synthesis such as actinomycin D, mitomycin C, and cycloheximide. We conclude that CD8+ cells with 'memory' phenotype (CD62Llo) are more sensitive to the ML III-mediated killing than their CD8+ CD62Lhi counterparts, CD4+ T cells, and CD19+ B cells. These cells probably express a distinct receptor with galNAc domains that is missing or not active on CD8+ cells with a 'naive' phenotype.  (+info)

Mistletoe lectin activates caspase-8/FLICE independently of death receptor signaling and enhances anticancer drug-induced apoptosis. (2/150)

Mistletoe lectin I (ML-I) is a major active component in plant extracts of Viscum album that is increasingly used in adjuvant cancer therapy. ML-I exerts potent immunomodulating and cytotoxic effects, although its mechanism of action is largely unknown. We show that treatment of leukemic T- and B-cell lines with ML-I induced apoptosis, which required the prior activation of proteases of the caspase family. The involvement of caspases is demonstrated because (a) a peptide caspase inhibitor almost completely prevented ML-I-induced cell death and (b) proteolytic activation of caspase-8, caspase-9, and caspase-3 was observed. Because caspase-8 has been implicated as a regulator of apoptosis mediated by death receptors, we further investigated a potential receptor involvement in ML-I-induced effects. Cell death triggered by ML-I was neither attenuated in cell clones resistant to CD95 nor in cells that were rendered refractory to other death receptors by overexpressing a dominant-negative FADD mutant. In contrast, ML-I triggered a receptor-independent mitochondria-controlled apoptotic pathway because it rapidly induced the release of cytochrome c into the cytosol. Because ML-I was also observed to enhance the cytotoxic effect of chemotherapeutic drugs, these data may provide a molecular basis for clinical trials using MLs in anticancer therapy.  (+info)

Promotion of ATP and S-140 to ribosome inactivation with camphorin, cinnamomin, and other RNA N-glycosidases. (3/150)

AIM: To study the effect of ATP and extra-ribosomal factors (S-140) on type I and type II RNA N-glycosidases in inactivating ribosome. METHODS: The activity of ATP and S-140 was determined by characterization of R-fragment in gel. An improved two-step method of cell-free protein synthesis system was used to quantitate the requirements of S-140 in ribosome inactivation. RESULTS: IC50 ratios of camphorin, gamma-momorcharin, luffin S, luffin A, trichosanthin (type I); and ricin, ricin A-chain; cinnamonin, cinnamomin A-chain (type II) between the absence and presence of ATP and S-140 were 3108, 151, 51, 45, 15; and 47, 7, 26, 12, respectively. CONCLUSION: The ribosome-inactivating activity of type II ribosome-inactivating proteins, including intact protein and its A-chain, was promoted by ATP and S-140. Camphorin showed a significant difference from cinnamomin in need of ATP and S-140 for such promoting.  (+info)

Mistletoe lectin dissociates into catalytic and binding subunits before translocation across the membrane to the cytoplasm. (4/150)

Hybridomas producing monoclonal antibodies (mAbs) against the mistletoe lectin A-chain (MLA) were obtained to investigate the intracellular routing and translocation of ribosome-inactivating proteins. Anti-MLA mAb MNA5 did not bind the holotoxin but interacted with isolated MLA. This epitope was not recognized upon MLA denaturation or conjugation of MLA with the ricin binding subunit (RTB). Furthermore, the mAbs did not appreciably react with a panel of MLA synthetic octapeptides linked to the surface of polyethylene pins. A study of the cytotoxicity of mistletoe lectin, ricin, and chimeric toxin MLA/RTB for the hybridomas revealed that interchain disulfide bond reduction and subunit dissociation are required for cytotoxic activity of mistletoe lectin.  (+info)

Cloning of the mistletoe lectin gene and characterization of the recombinant A-chain. (5/150)

Mistletoe lectin I (MLI) is the major active constituent of mistletoe extracts, which are widely used for adjuvant tumour therapy. The 66-kDa heterodimeric disulphide-linked glycoprotein is classified as type II ribosome-inactivating protein (RIP) due to the rRNA-cleaving enzyme activity of the A-subunit, also referred to as toxic entity. MLI and the close relative ricin both belong to the family of the two-chain plant type II RIP proteins. Isolation of the glycosylated proteins from plant material yield inhomogeneous material probably due to post-translational modifications. The aim of this study was to prepare pure and homogeneous protein as a prerequisite for structural and mechanistic studies in order to gain insight into the mode of action of this cytotoxic plant protein on tumour and immune cells. Of particular interest was to explain whether the differences in toxicity of ML and ricin are the result of variations of their enzymatic activities. By investigating the sequence homologies between the active sites of different RIPs we were able to deduce a set of primers which were suitable for specific amplification of the mistletoe lectin gene. Applying this PCR strategy the full-length 1923 nucleotide DNA sequence coding for the prepro-protein was obtained showing the existence of a single intron-free gene. In order to elucidate the molecular basis for the observed differences in cytotoxicity within the family of RIP the enzymatic A-subunit was expressed in a heterologous system. Expression of the A-chain in E. coli BL21/pT7 resulted in production of insoluble inclusion bodies constituting 20-30% of total protein. Refolding led to a pure and homogeneous protein species with an apparent molecular mass of 27 kDa and a pI value of 6.4. The ribosome-inactivating activity of the unglycosylated recombinant A-chain (IC50 20.5 pM) protein was in the same range as that of the glycosylated plant-derived ML A-chain (IC50 3.7 pM), which was very similar to that of ricin A-chain (IC50 4.9 pM). Thus, the higher cytotoxicity of ricin cannot be accountable for differences in the enzymatic activities of the type II RIP A-chains.  (+info)

Lactose-containing starburst dendrimers: influence of dendrimer generation and binding-site orientation of receptors (plant/animal lectins and immunoglobulins) on binding properties. (6/150)

Starburst glycodendrimers offer the potential to serve as high-affinity ligands for clinically relevant sugar receptors. In order to define areas of application, their binding behavior towards sugar receptors with differential binding-site orientation but identical monosaccharide specificity must be evaluated. Using poly(amidoamine) starburst dendrimers of five generations, which contain the p-isothiocyanato derivative of p-aminophenyl-beta-D-lactoside as ligand group, four different types of galactoside-binding proteins were chosen for this purpose, i.e., the (AB)(2)-toxic agglutinin from mistletoe, a human immunoglobulin G fraction, the homodimeric galectin-1 with its two binding sites at opposite ends of the jelly-roll-motif-harboring protein and monomeric galectin-3. Direct solid-phase assays with surface-immobilized glycodendrimers resulted in obvious affinity enhancements by progressive core branching for the plant agglutinin and less pronounced for the antibody and galectin-1. High density of binding of galectin-3 with modest affinity increases only from the level of the 32-mer onwards points to favorable protein-protein interactions of the monomeric lectin and a spherical display of the end groups without a major share of backfolding. When the inhibitory potency of these probes was evaluated as competitor of receptor binding to an immobilized neoglycoprotein or to asialofetuin, a marked selectivity was detected. The 32- and 64-mers were second to none as inhibitors for the plant agglutinin against both ligand-exposing matrices and for galectin-1 on the matrix with a heterogeneous array of interglycoside distances even on the per-sugar basis. In contrast, a neoglycoprotein with the same end group was superior in the case of the antibody and, less pronounced, monomeric galectin-3. Intimate details of topological binding-site presentation and the ligand display on different generations of core assembly are major operative factors which determine the potential of dendrimers for applications as lectin-targeting device, as attested by these observations.  (+info)

An Epstein-Barr virus-infected lymphoblastoid cell line (D430B) that grows in SCID-mice with the morphologic features of a CD30+ anaplastic large cell lymphoma, and is sensitive to anti-CD30 immunotoxins. (7/150)

BACKGROUND AND OBJECTIVE: In this study we describe a newly established CD30+ Epstein Barr virus (EBV)-infected B cell line derived from an EBV-infected B cell culture (utilized, once irradiated, as a feeder) which showed a B clonal rearrangement and strong CD30 antigen expression. DESIGN AND METHODS: The cells injected into SCID mice were able to grow giving rise to CD30+ solid tumors with the morphologic features of an anaplastic large cell lymphoma (ALCL). Thus we tried to establish a model to investigate the potency of immunoconjugates containing a CD30 monoclonal antibody (Ber-H2) and ribosome-inactivating proteins (saporin, momordin and ricin A-chain) as toxic moieties. RESULTS: We observed a strong cytotoxic activity of the anti-CD30 immunotoxins on the in vitro growth of D430B cells. High levels of anti-tumor activity were also observed in vivo, in the SCID mouse model. INTERPRETATION AND CONCLUSIONS: The antitumor immunotoxin therapy was sccessful in our chosen animal model, the effecacy seeming to be associated with strength of CD30 expression. Our data suggest that immunotoxins should be tested (before use) on the tumor cells of the subject to be treated and that immunotoxins should be directed to different tumor-associated antigens to avoid selection of cell populations with different antigenic mosaics.  (+info)

Solution structure of anti-HIV-1 and anti-tumor protein MAP30: structural insights into its multiple functions. (8/150)

We present the solution structure of MAP30, a plant protein with anti-HIV and anti-tumor activities. Structural analysis and subsequent biochemical assays lead to several novel discoveries. First, MAP30 acts like a DNA glycosylase/apurinic (ap) lyase, an additional activity distinct from its known RNA N-glycosidase activity toward the 28S rRNA. Glycosylase/ap lyase activity explains MAP30's apparent inhibition of the HIV-1 integrase, MAP30's ability to irreversibly relax supercoiled DNA, and may be an alternative cytotoxic pathway that contributes to MAP30's anti-HIV/anti-tumor activities. Second, two distinct, but contiguous, subsites are responsible for MAP30's glycosylase/ap lyase activity. Third, Mn2+ and Zn2+ interact with negatively charged surfaces next to the catalytic sites, facilitating DNA substrate binding instead of directly participating in catalysis.  (+info)

Viscum album agglutinin-I (VAA-I) is a plant lectin, which possesses anti-inflammatory properties, including the ability to induce neutrophil apoptosis by a mechanism that is not completely understood. Among the three actin-binding membrane-anchoring proteins ezrin/radixin/moesin (ERM), neutrophils are known to express ezrin and moesin. The behavior of these proteins in apoptotic neutrophils is not well established. In the present study, the expression and localization of ezrin and moesin by Western blot and immunofluorescence revealed a clear degradation and relocalization of both the proteins during VAA-I-induced apoptosis. Also, flow cytometry analysis revealed that VAA-I markedly and significantly induced the cell surface expression of ezrin and moesin and this was reversed when cells were pretreated with the Syk inhibitor piceatannol. The expression of ezrin and moesin on the cell surface of apoptotic neutrophils may represent a mechanism responsible for the appearance of autoantibodies ...

The type 2 ribosome-inactivating proteins (RIPs) isolated from some species belonging to the Sambucus genus, have the characteristic that although being even more active than ricin inhibiting protein synthesis in cell-free extracts, they lack the high toxicity of ricin and related type 2 RIPs to intact cells and animals. This is due to the fact that after internalization, they follow a different intracellular pathway that does not allow them to reach the cytosolic ribosomes. The lack of toxicity of type 2 RIPs from Sambucus make them good candidates as toxic moieties in the construction of immunotoxins and conjugates directed against specific targets. Up to now they have been conjugated with either transferrin or anti-CD105 to target either transferrin receptor- or endoglin-overexpressing cells, respectively.

Ribosome-inactivating proteins (RIPs) are EC3.2.32.22 N-glycosidases that recognize a universally conserved stem-loop structure in 23S/25S/28S rRNA, depurinating a single adenine (A4324 in rat) and irreversibly blocking protein translation, leading finally to cell death of intoxicated mammalian cells. Ricin, the plant RIP prototype that comprises a catalytic A subunit linked to a galactose-binding lectin B subunit to allow cell surface binding and toxin entry in most mammalian cells, shows a potency in the picomolar range. The most promising way to exploit plant RIPs as weapons against cancer cells is either by designing molecules in which the toxic domains are linked to selective tumor targeting domains or directly delivered as suicide genes for cancer gene therapy. Here, we will provide a comprehensive picture of plant RIPs and discuss successful designs and features of chimeric molecules having therapeutic potential.

Inhibition of protein synthesis in Vero cells was measured at different periods of time after treatment with diphtheria toxin and the related plant toxin modeccin. Diphtheria toxin acted much more rapidly than modeccin. Cells were protected against both toxins with antiserum as well as with agents like NH4Cl, procaine, and the ionophores monensin, FCCP, and CCCP, which increase the pH of intracellular vesicles. Antiserum, which is supposed to inactivate toxin only at the cell surface, protected only when it was added within a short period of time after modeccin. Compounds that increase the pH of intracellular vesicles, protected even when added after 2 h, indicating that modeccin remains inside vesicles for a considerable period of time before it enters the cytosol. After addition of diphtheria toxin to the cells, compounds that increase the pH of intracellular vesicles protected only approximately to the same extent as antitoxin. This indicates that after endocytosis diphtheria toxin rapidly ...

A novel, type 1 ribosome-inactivating protein designated charybdin was isolated from bulbs of Charybdis maritima agg. The protein, consisting of a single polypeptide chain with a molecular mass of 29 kDa, inhibited translation in rabbit reticulocytes with an IC50 of 27.2 nm. Plant genomic DNA extracted from the bulb was amplified by PCR between primers based on the N-terminal and C-terminal sequence of the protein from dissolved crystals. The complete mature protein sequence was derived by partial DNA sequencing and terminal protein sequencing, and was confirmed by high-resolution crystal structure analysis. The protein contains Val at position 79 instead of the conserved Tyr residue of the ribosome-inactivating proteins known to date. To our knowledge, this is the first observation of a natural substitution of a catalytic residue at the active site of a natural ribosome-inactivating protein. This substitution in the active site may be responsible for the relatively low in vitro translation ...

Mormordica charantia (bitter gourd or bitter melon) is a climbing perennial that is characterized by elongated, warty fruit-like gourds or cucumbers and is native to the tropical belt. Although momordica charantia is commonly used in traditional medical practices, along with research suggesting its benefits for people with type 2 diabetes, the current evidence does not warrant using the plant in treating this disease. This review of trials found only four studies which had an overall low quality. Three trials showed no significant differences between momordica charantia and placebo or antidiabetic drugs (glibenclamide and metformin) in the blood sugar response. The duration of treatment ranged from four weeks to three months, and altogether 479 patients with type 2 diabetes mellitus participated. No trial investigated death from any cause, morbidity, health-related quality of life or costs. Adverse effects were mostly moderate, including diarrhoea and abdominal pain. However, reporting of ...

Deftones have reason to celebrate today, as hard rock has landed high on the Billboard charts. Deftones currently have the #2 album in the country with their recent release, Gore.. Deftones shifted 71,00 album equivalent units which means a combination of sales and streams. Even more impressive, pure album sales account for 69,000 of those units. Billboard counts 2,000 streams of an album or songs off that album as the equivalent of one sale to come up with the additional 2,000 units.. This is their best chart debut since their 2003 self-titled release, and also their best first-week sales number since Saturday Night Wrist, which sold 76,000 first week. Their last album, Koi No Yokan shifted 65,000 copies first week, so they should be excited about the sales growth in an era where big bands are seeing declines in first week sales. Put bluntly, Deftones fans buy albums! Watch the new video for Prayers/Triangles here.. In case youre wondering, folk band The Lumineers have the #1 album in the ...
Randy Rhoads made two studio albums with Ozzy Osbourne before his unfortunate death in 1982. The second of these albums was 1981s Diary of a Madman. In my opinion this album always edged out Ozzys first solo album, The Blizzard of Ozz, released earlier the same year. To me the last three tracks of this album were the pinnacle of classic early Ozzy, all made possible by the incredible guitar work of Randy Rhoads. The album ends in epic fashion with a choir singing along to the syncopated 6/8 rhythm of the guitars, reminiscent of Ozzys classic opening theme: O Fortuna. Ozzy is a ridiculous, silly man as can be learned from simply looking at almost any of his album covers, but put together with the right musical ensemble he is behind some of my favorite early heavy metal titles.. ...

Putting aside much of what happened politically in 2016, this has been one of the best years in recent memory for metal. There were many, many albums I loved this year, far too many to squeeze into an end-of-year list. So I have limited myself to picking my ten favourite albums, as well as five runners up. And by imposing this particular format on myself I had to think quite carefully about my choices and what it is that makes that particular album stand out to me. And really what it comes down to, most of the time, is whether an album moves me. If an album inspires some sort of reaction from me on an emotional level - whether thats in an emotionally resonant song or idea, or by crafting such a rich and powerful atmosphere that the listener is transported away from their everyday life - thats what really makes an album stand out to me. So there were many albums which I enjoyed but which you wont find on this list precisely because, even though they might have some great riffs or something ...
This track, produced by Paul White, is not on First of a Living Breed, its a bonus track announcing the album to the world. One thing that I love about this album (besides of course the music), is that there is a Lyrics sheet to go along with it. I have always felt that all rap albums should come with a lyrics sheet. The whole point of Hip Hop is what it is that you have to say. If you have anything of value or interest to say then heads would want to read the lyrics as well as listen. A lot of (non-Hip Hop) albums I listened to from my parents vinyl collections when I was a kid had these. Cop the album as CD, MP3 or Vinyl, along with the lyrics sheet from the links below..

San Antonios masters of blackened death/thrash HOD are gearing up for one hellaciously brutal summer with a series of live dates that will see the band join forces with Marduk, Aura Noir, Black Anvil, Panzerfaust and many more as they devastate parts of the US and Canada with their relentless brand of extreme metal. All of this is coming in anticipation of the bands follow up to their critically-acclaimed debut, Serpent, which Zero Tolerance called a venomous explosion of black, death, and thrash metal fury and Terrorizer called non-commercialized, uncompromising and slightly unhinged death metal. The new material is expected to see the light of day in the coming months. HOD guitarist Carl Lord Necron Snyder comments on the upcoming tour and new album,The name of the new album has been chosen - Book of the Worm. We shall unleash this album sometime later this year. We have worked on the music for this album for quite some time. We hope to announce the producer soon for this album, we ...
Guitar player Giulio Moschini commented: Following the tradition of releasing an album every two years, the time has come now and were ready to hit the studio and record our fifth album. Youve probably read the same words million of times on bands press releases so I will not tell you how much better this album sounds and how much faster and more technical it is compared to the last one we did -- but were fucking proud of this upcoming beast, and were sure you guys will love it! We know how much our fans are expecting from the new album, so we worked as hard as we could to not disappoint any of them. Moreover, as some of you know, this will be the first album with a new lineup, and as you can imagine having a new singer and a new drummer helped us to renew and improve our sound once again. This will be like the rebirth of Hour of Penance ...
Philly2Philly.com REVIEW: Van Halen brings back big rock with A Different Kind of Truth. Van Halen has a new album.. Wait. Van Halen has a new album?. Yeah I know. Still kind of crazy saying that again, isnt it?. Despite the band touring twice over the last eight years (once with Sammy Hagar while supporting their second greatest hits album, and the other with prodigal son David Lee Roth), the only new songs were three greatest hits tracks the band performed with Hagar). As a result, the bands lack of new material over the last decade and change had many skeptics and fans alike wondering if Van Halen had anything left in the creative tank.. As we all know, camp Van Halen is quite secretive. The fact that the band was working on a new album wasnt even confirmed by the band until several months back. In fact, it seems everyone was talking about Van Halens upcoming new album during 2011 except…..Van Halen themselves.. There are questions all around here. How is Eddie Van Halens health? Can ...

xp! Nah (to Scott, about the album he posted), but actually, I just remembered that Vince Gill (who is boring) put out a quaduple CD four years ago -- very big deal at the Grammys, obviously. And the Nitty Gritty Dirt Bands two Will The Circle Be Unbroken doubles fit in here, too. And maybe Red Headed Stranger. Probably other outlaw stuff too -- Jamey Johnson divides is into a Black Album and a White Album; David Allan Coe had a Happy Side and a Su-i-Side. So its not like the Johnson thing is that unprecedented, I guess.
