Retinoic acid, but not arsenic trioxide, degrades the PLZF/RARalpha fusion protein, without inducing terminal differentiation or apoptosis, in a RA-therapy resistant t(11;17)(q23;q21) APL patient. (1/1135)

Primary blasts of a t(11;17)(q23;q21) acute promyelocytic leukaemia (APL) patient were analysed with respect to retinoic acid (RA) and arsenic trioxide (As2O3) sensitivity as well as PLZF/RARalpha status. Although RA induced partial monocytic differentiation ex vivo, but not in vivo, As203 failed to induce apoptosis in culture, contrasting with t(15;17) APL and arguing against the clinical use of As203 in t(11;17)(q23;q21) APL. Prior to cell culture, PLZF/RARalpha was found to exactly co-localize with PML onto PML nuclear bodies. However upon cell culture, it quickly shifted towards microspeckles, its localization found in transfection experiments. Arsenic trioxide, known to induce aggregation of PML nuclear bodies, left the microspeckled PLZF/RARalpha localization completely unaffected. RA treatment led to PLZF/RARalpha degradation. However, this complete PLZF/RARalpha degradation was not accompanied by differentiation or apoptosis, which could suggest a contribution of the reciprocal RARalpha/PLZF fusion product in leukaemogenesis or the existence of irreversible changes induced by the chimera.  (+info)

NADPH oxidase inhibition does not interfere with low PO2 transduction in rat and rabbit CB chemoreceptor cells. (2/1135)

The aim of the present work was to elucidate the role of NADPH oxidase in hypoxia sensing and transduction in the carotid body (CB) chemoreceptor cells. We have studied the effects of several inhibitors of NADPH oxidase on the normoxic and hypoxia-induced release of [3H]catecholamines (CA) in an in vitro preparation of intact CB of the rat and rabbit whose CA deposits have been labeled by prior incubation with the natural precursor [3H]tyrosine. It was found that diphenyleneiodonium (DPI; 0.2-25 microM), an inhibitor of NADPH oxidase, caused a dose-dependent release of [3H]CA from normoxic CB chemoreceptor cells. Contrary to hypoxia, DPI-evoked release was only partially Ca2+ dependent. Concentrations of DPI reported to produce full inhibition of NADPH oxidase in the rat CB did not prevent the hypoxic release response in the rat and rabbit CB chemoreceptor cells, as stimulation with hypoxia in the presence of DPI elicited a response equaling the sum of that produced by DPI and hypoxia applied separately. Neopterin (3-300 microM) and phenylarsine oxide (0.5-2 microM), other inhibitors of NADPH oxidase, did not promote release of [3H]CA in normoxic conditions or affect the response elicited by hypoxia. On the basis of effects of neopterin and phenylarsine oxide, it is concluded that NADPH oxidase does not appear to play a role in oxygen sensing or transduction in the rat and rabbit CB chemoreceptor cells in vitro and, in the context of the present study, that DPI effects are not related to NADPH oxidase inhibition.  (+info)

Arsenic trioxide and melarsoprol induce apoptosis in plasma cell lines and in plasma cells from myeloma patients. (3/1135)

Recent data have renewed the interest for arsenic-containing compounds as anticancer agents. In particular, arsenic trioxide (As2O3) has been demonstrated to be an effective drug in the treatment of acute promyelocytic leukemia by inducing programmed cell death in leukemic cells both in vitro and in vivo. This prompted us to study the in vitro effects of As2O3 and of another arsenical derivative, the organic compound melarsoprol, on human myeloma cells and on the plasma cell differentiation of normal B cells. At pharmacological concentrations (10(-8) to 10(-6) mol/L), As2O3 and melarsoprol caused a dose- and time-dependent inhibition of survival and growth in myeloma cell lines that was, in some, similar to that of acute promyelocytic leukemia cells. Both arsenical compounds induced plasma cell apoptosis, as assessed by 4',6-diamidino-2-phenylindole staining, detection of phosphatidylserine at the cell surface using annexin V, and by the terminal deoxynucleotidyl transferase-mediated nick end labeling assay. As2O3 and melarsoprol also inhibited viability and growth and induced apoptosis in plasma-cell enriched preparations from the bone marrow or blood of myeloma patients. In nonseparated bone marrow samples, both arsenical compounds triggered death in myeloma cells while sparing most myeloid cells, as demonstrated by double staining with annexin V and CD38 or CD15 antibodies. In primary myeloma cells as in cell lines, interleukin 6 did not prevent arsenic-induced cell death or growth inhibition, and no synergistic effect was observed with IFN-alpha. In contrast to As2O3, melarsoprol only slightly reduced the plasma cell differentiation of normal B cells induced by pokeweed mitogen. Both pokeweed mitogen-induced normal plasma cells and malignant plasma cells showed a normal nuclear distribution of PML protein, which was disrupted by As2O3 but not by melarsoprol, suggesting that the two arsenical derivatives acted by different mechanisms. These results point to the use of arsenical derivatives as investigational drugs in the treatment of multiple myeloma.  (+info)

Interference in the quantitation of methylated arsenic species in human urine. (4/1135)

The aim of this paper is to report on the presence of chemical interferences in the quantitation of methylated arsenic species in human urine when using a method based on selective volatile arsine species generation, chromatographic separation, and hydride generation atomic absorption spectrometry (HGAAS) detection. An abnormal profile of methylated arsenic species characterized by the absence of the peak corresponding to dimethylarsinic acid (DMA) was observed in urine from some individuals exposed to arsenic via drinking water and living in rural communities of northwestern Argentina. The absence of this peak persisted even after the addition of known amounts of DMA to the samples. However, the DMA peak appeared after urine digestion with hydrochloric acid (2M). Samples showing interferences were provided by individuals who had mate consumption and coca-leaf chewing habits. Because the relative proportions of methylated arsenic species present in urine have been used to evaluate the efficiency of the methylation process, interferences in the formation or detection of methylarsines may cause underestimation of As exposure and also lead to erroneous conclusions about relative biomethylation efficiencies. Therefore, we recommend that urine samples should be digested with 2M HCl before performing speciation analysis using HGAA techniques. Further studies on the impact of this type of interferences on other arsenic speciation methods are also required.  (+info)

Phenylarsine oxide and ethanol prevent cell death of porcine polymorphonuclear leucocytes induced by phorbol myristate acetate. (5/1135)

In this study, we report that phenylarsine oxide and ethanol, both of which suppress a number of polymorphonuclear leucocyte functions including superoxide production, prevented the phorbol myristate acetate-induced cell death in a dose-dependent manner. These reagents had an inhibitory effect even after polymorphonuclear leucocytes were stimulated to produce superoxide by treatment with phorbol myristate acetate. The results indicate that activation of protein kinase C and subsequent superoxide release do not directly cause phorbol myristate acetate-induced cell death. Phenylarsine oxide or ethanol prevents cell death by affecting pathways downstream from those involved in the superoxide production.  (+info)

Phosphatidylinositol 3'-kinase and tyrosine-phosphatase activation positively modulate Convulxin-induced platelet activation. Comparison with collagen. (6/1135)

In this report we have studied the role of phosphatidylinositol 3'-kinase (PI3-K) and tyrosine phosphatase activation on platelet activation by Convulxin (Cvx). Wortmannin, a specific PI3-K inhibitor, and phenylarsine oxide (PAO), a sulfhydryl reagent that inhibits tyrosine phosphatase (PTPase), block Cvx-induced platelet aggregation, granule secretion, inositol phosphate production, and increase in [Ca2+]i. However, PAO does not inhibit Cvx-induced tyrosine phosphorylation of platelet proteins, including Syk and PLCgamma2, but blocked collagen-induced platelet aggregation as well as tyrosine phosphorylation of PLCgamma2. In contrast, Cvx-induced PLCgamma2 tyrosyl phosphorylation was partially inhibited by wortmannin. We conclude that (i) although Cvx and collagen activate platelets by a similar mechanism, different regulatory processes are specific to each agonist; (ii) mechanisms other than tyrosine phosphorylation regulate PLCgamma2 activity; and (iii) besides protein tyrosine kinases, PI3-K (and PTPase) positively modulate platelet activation by both Cvx and collagen, and this enzyme is required for effective transmission of GPVI-Fc receptor gamma chain signal to result in full activation and tyrosine phosphorylation of PLCgamma2 in Cvx-stimulated platelets.  (+info)

Apoptosis and growth inhibition in malignant lymphocytes after treatment with arsenic trioxide at clinically achievable concentrations. (7/1135)

BACKGROUND: Arsenic trioxide (As2O3) can induce clinical remission in patients with acute promyelocytic leukemia via induction of differentiation and programmed cell death (apoptosis). We investigated the effects of As2O3 on a panel of malignant lymphocytes to determine whether growth-inhibitory and apoptotic effects of As2O3 can be observed in these cells at clinically achievable concentrations. METHODS: Eight malignant lymphocytic cell lines and primary cultures of lymphocytic leukemia and lymphoma cells were treated with As2O3, with or without dithiothreitol (DTT) or buthionine sulfoximine (BSO) (an inhibitor of glutathione synthesis). Apoptosis was assessed by cell morphology, flow cytometry, annexin V protein level, and terminal deoxynucleotidyl transferase labeling of DNA fragments. Cellular proliferation was determined by 5-bromo-2'-deoxyuridine incorporation into DNA and flow cytometry and by use of a mitotic arrest assay. Mitochondrial transmembrane potential (delta psi(m)) was measured by means of rhodamine 123 staining and flow cytometry. Protein expression was assessed by western blot analysis or immunofluorescence. RESULTS: Therapeutic concentrations of As2O3 (1-2 microM) had dual effects on malignant lymphocytes: 1) inhibition of growth through adenosine triphosphate (ATP) depletion and prolongation of cell cycle time and 2) induction of apoptosis. As2O3-induced apoptosis was preceded by delta psi(m) collapse. DTT antagonized and BSO enhanced As2O3-induced ATP depletion, delta psi(m) collapse, and apoptosis. Caspase-3 activation, usually resulting from delta psi(m) collapse, was not always associated with As2O3-induced apoptosis. As2O3 induced PML (promyelocytic leukemia) protein degradation but did not modulate expression of cell cycle-related proteins, including c-myc, retinoblastoma protein, cyclin-dependent kinase 4, cyclin D1, and p53, or expression of differentiation-related antigens. CONCLUSIONS: Substantial growth inhibition and apoptosis without evidence of differentiation were induced in most malignant lymphocytic cells treated with 1-2 microM As2O3. As2O3 may prove useful in the treatment of malignant lymphoproliferative disorders.  (+info)

Oxidative stress triggers STAT3 tyrosine phosphorylation and nuclear translocation in human lymphocytes. (8/1135)

Oxidizing agents are powerful activators of factors responsible for the transcriptional activation of cytokine-encoding genes involved in tissue injury. In this study we show evidence that STAT3 is a transcription factor whose activity is modulated by H2O2 in human lymphocytes, in which endogenous catalase had previously been inhibited. H2O2-induced nuclear translocation of STAT3 to form sequence-specific DNA-bound complexes was evidenced by immunoblotting of nuclear fractions and electrophoretic mobility shift assays, and vanadate was found to strongly synergize with H2O2. Moreover, anti-STAT3 antibodies specifically precipitated a protein of 92 kDa that becomes phosphorylated on tyrosine upon lymphocyte treatment with H2O2. Phenylarsine oxide, a tyrosine phosphatase inhibitor, and genistein, a tyrosine kinase inhibitor, cooperated and cancelled, respectively, the H2O2-promoted STAT3 nuclear translocation. Evidence is also presented, using Fe2+/Cu2+ ions, that.OH generated from H2O2 through Fenton reactions could be a candidate oxygen reactive species to directly activate STAT3. Present data suggest that H2O2 and vanadate are likely to inhibit the activity of intracellular tyrosine phosphatase(s), leading to enhanced STAT3 tyrosine phosphorylation and hence its translocation to the nucleus. These results demonstrate that the DNA binding activity of STAT3 can be modulated by oxidizing agents and provide a framework to understand the effects of oxidative stress on the JAK-STAT signaling pathway.  (+info)

TY - JOUR. T1 - Effect of trivalent arsenicals on cell proliferation in mouse and human microvascular endothelial cells. AU - Dodmane, Puttappa R.. AU - Arnold, Lora L. AU - Pennington, Karen L.. AU - Singh, Rakesh K. AU - Cardoso, Ana Paula Ferragut. AU - Cohen, Samuel Monroe. PY - 2015/5/1. Y1 - 2015/5/1. N2 - Chronic exposure to high levels of inorganic arsenic (iAs) has been associated with cancerous and non-cancerous health effects, including cardiovascular effects. However, the mechanism for a presumed toxic effect of arsenic on vascular tissue is not clear. Our working hypothesis is that inorganic trivalent arsenic and its methylated metabolites react with cysteine-containing cellular proteins and alter their function leading to adverse events such as cytotoxicity or proliferation. In this study, human microvascular endothelial cells (HMEC1) and mouse microvascular endothelial cells (MFP-MVEC) were exposed to arsenite (iAsIII), monomethylarsonous acid (MMAIII), or dimethylarsinous acid ...

During the last decade, ATO has been used effectively to treat both newly diagnosed and relapsed APL patients, with patients showing complete remission after low dose ATO treatment [4]. The anti-cancer ability of ATO is not limited to APL [36] and many other tumors in animal models have been shown to be sensitive to ATO treatment [37, 38]. However, the lack of information on sites of action for ATO cytotoxicity in tumor types other than APL has limited its uptake for the treatment of other cancers until recent years [5].. In this study, we have demonstrated that complex IV of the ETC is a target for ATO. From a panel of ETC inhibitors, the decrease in ROS, decrease in ATP production and MMP depolarisation caused by low dose ATO treatment of T-47D cells was reproduced only by cyanide, a well characterised complex IV inhibitor (Figure 5). Direct measurement of cytochrome C oxidase activity in whole cells treated with ATO confirmed the ability of ATO to inhibit this enzyme activity directly. The ...
Harmonised classification and labelling is a legally binding classification and labelling for a substance, agreed at European Community level. Harmonisation is based on the substances physical, toxicological and eco-toxicological hazard assessment. The Hazard classification and labelling section uses the signal word, pictogram(s) and hazard statements of the substance under the harmonised classification and labelling (CLH) as its primary source of information.. If the substance is covered by more than one CLH entry (e.g. disodium tetraborate EC no. 215-540-4, is covered by three harmonisations: 005-011-00-4; 005-011-01-1 and 005-011-02-9), CLH information cannot be displayed in the InfoCard as the difference between the CLH classifications requires manual interpretation or verification. If a substance is classified under multiple CLH entries, a link to the C&L Inventory is provided to allow users to view CLH information associated with the substance and no text is automatically ...

TY - JOUR. T1 - Arsenic trioxide. T2 - Its use in the treatment of acute promyelocytic leukemia. AU - Sanz, Miguel A.. AU - Lo-Coco, Francesco. PY - 2006. Y1 - 2006. N2 - Acute promyelocytic leukemia (APL) represents approximately 10-15% of all adult cases of acute myeloid leukemia and is characterized by a unique genetic abnormality and frequent association with a severe hemorrhagic diathesis. An arsenic trioxide formulation for intravenous infusion has been developed and is currently licensed for the induction of remission and consolidation in adult patients with relapsed/refractory APL. Several studies have shown that arsenic trioxide is highly effective in the treatment of relapsed/refractory patients with APL, achieving remission rates of ,80%, high rates of molecular remission, and durable periods of disease-free survival. Furthermore, recent studies indicate that arsenic trioxide may also have a role in the treatment of newly diagnosed patients, either as a single agent or in combination ...

[Ar]3d104s24p3. It appears in three allotropic forms, yellow, black, and gray. The stable form is a brittle, steel-gray hexagonal solid that oxidizes rapidly in air, and at high temperatures burns to form a white cloud of arsenic trioxide. Arsenic and some arsenic compounds sublime when heated and convert to gaseous form. Arsenic is an omnipresent element as arsenic minerals in the various lithosphere or fossil fuels including realgar, orpiment, and arsenopyrite. It is prepared commercially from arsenical pyrites (sulfide ores) by condensation of sublimed gas and by the reduction of white arsenic with carbon. This element contributes hardness and is used in preparing alloys for hard and corrosion-resistant ...

Inhibition of mitochondrial protein translation sensitizes melanoma cells to arsenic trioxide cytotoxicity via a reactive oxygen species dependent mechanism. Benjamin D. Bowling, Nicole Doudican, Prashiela Manga, and Seth J. Orlow, Department of Dermatology, NYU School of Medicine, New York City, New York. (Sponsored by David J. Leffell, Department of Dermatology, Yale University School of Medicine). Current standard chemotherapeutic regimens for malignant melanoma are unsatisfactory. Although in vitro studies of arsenic trioxide (ATO) have demonstrated promise against melanoma, recent phase II clinical trials have failed to show any significant clinical benefit when used as a single agent. To enhance the efficacy of ATO in the treatment of melanoma, we sought to identify compounds that potentiate the cytotoxic effects of ATO in melanoma cells. Through a screen of 2000 marketed drugs and naturally occurring compounds, and subsequent mechanistic testing, a variety of antibiotic inhibitors of ...

Abstract: Background: Lung cancer is one of the most lethal and common cancers in the world, causing up to 3 million deaths annually. The chemotherapeutic drugs that have been used in treating lung cancer include cisplatinpemetrexed, cisplastin-gencitabinoe, carboplatin-pacitaxel and crizotinib. Arsenic trioxide (ATO) has been used in the treatment of acute promyelocytic leukemia. However, its effects on lung cancer are not known. We hypothesize that ATO may also have a bioactivity against lung cancer, and its mechanisms of action may involve apoptosis, DNA damage and changes in stress-related proteins in lung cancer cells. Methods: To test the above stated hypothesis, lung carcinoma (A549) cells were used as the test model. The effects of ATO were examined by performing 6-diamidine-2 phenylindole (DAPI) nuclear staining for morphological characterization of apoptosis, flow cytometry analysis for early apoptosis, and western blot analysis for stressrelated proteins (Hsp70 and cfos) and apoptotic ...

Arsenic trioxide (As2O3) has shown anti-tumour activity against a variety of solid tumours in vitro. However, the mechanisms responsible for its cytotoxicity against ovarian carcinoma remain elusive. In this thesis, the molecular determinants of its effects and factors mediating its chemoresistance in ovarian cancer cells were investigated. It was found that As2O3 treatment caused both apoptosis induction and caspase-independent cell death involving mitochondrial dysfunction. This was accompanied by endoplasmic reticulum stress induction and an increase in intracellular glutathione (GSH) level. The latter was in turn prevented by the concurrent use of GSH modulator, buthionine sulfoximine but not ascorbic acid. Gene expression analysis of arsenic-resistant OVCAR-3 (OVCAR-3/AsR) cells showed the involvement of multiple factors mediating its chemoresistance. Of particular interest, a genetic hub involving elevated interleukin 1A signalling was identified. This could consecutively modulate the ...

This epidemiological study investigated the association between β-cell function (a predictive factor of diabetes development) and the organic arsenic arsenobetaine (an agent less toxic to humans). Urine arsenobetaine was revealed to be associated with HOMA-β in the normal population (without diabetes), especially in males, even after adjusting for factors affecting diabetes and β-cell function, while no association was shown with HOMA-IR which is associated with insulin resistance.. Despite several conflicting results, arsenic has been reported to be correlated with diabetes in many epidemiological studies [6, 9, 23-31], and arsenic can affect insulin resistance and β-cell function [7]. In some experimental studies, arsenite was found to induce oxidative stress in pancreatic β-cells and reduce insulin transcription and secretion [32, 33], caused by the altered expression of essential genes such as the Pdx1 gene [34, 35] and insulin gene [36] for pancreas development, insulin production, and ...
Adult patients who received the chemotherapy drug arsenic trioxide (Trisenox) immediately after standard chemotherapy had a significantly higher remission rate and better overall survival than those who received standard chemotherapy, according results of a phase III cancer clinical trial for an uncommon form of leukemia.. Seventy-seven percent of adult patients with acute promyelocytic leukemia who received arsenic trioxide remained alive and in remission, free of relapse, three years after diagnosis. This compared with 59 percent on the standard treatment. The greater effectiveness of the experimental combination also resulted in better overall survival of 86 percent after three years for the patients who received the arsenic trioxide compared to 77 percent for patients on the standard treatment arm.. Dr. Fred Appelbaum, director of the Centers Clinical Research Division, helped conceive, write the protocol, enroll patients and write up the results for the NCI-sponsored trial.. Acute ...
An ensemble Monte Carlosimulation is used to compare high field electron transport in bulk InAs, InP and GaAs. In particular, velocity overshoot and electron transit times are examined. For all materials, we find that electron velocity overshoot only occurs when the electric field is increased to a value above a certain critical field, unique to each material. This critical field is strongly dependent on the material, about 3 kV/cm for InAs, 10 kV/cm for InP and 5 kV/cm for the case of GaAs, We find that InAs exhibits the highest peak overshoot velocity and that this velocity overshoot lasts over the longest distances when compared with GaAs and InP. Finally, we estimate the minimum transit time across a 1 μm InAs sample to be about 2 ps. Similar calculations for InP and GaAs yield 6.6 and 5.4 ps, respectively. We find that the optimal cutoff frequency for an ideal InAs based device ranges from around 79 GHz when the device thickness is set to 1 μm. We thus suggest that indium arsenide offers great
Purpose: It was recently reported that the organic arsenic compound darinaparsin (DPS) is a cytotoxin and radiosensitizer of tumor cells in vitro and in subcutaneous xenograft tumors. Surprisingly, it was also found that DPS protects normal intestinal crypt epithelial cells (CECs) from clonogenic death after ionizing radiation (IR). Here we tested the DPS radiosensitizing effect in a clinically relevant model of prostate cancer and explored the radioprotective effect and mechanism of DPS on CECs. Methods and Materials: The radiation modification effect of DPS was tested in a mouse model of orthotopic xenograft prostate cancer and of IR-induced acute gastrointestinal syndrome. The effect of DPS on CEC DNA damage and DNA damage responses was determined by immunohistochemistry. Results: In the mouse model of IR-induced gastrointestinal syndrome, DPS treatment before IR accelerated recovery from body weight loss and increased animal survival. DPS decreased post-IR DNA damage and cell death, ...
TY - JOUR. T1 - Pharmaceutical development of the novel arsenical based cancer therapeutic GSAO for phase I clinical trial. AU - Elliott, Moira. AU - Ford, S J. AU - Prasad, E. AU - Dick, L J. AU - Farmer, H. AU - Hogg, P J. AU - Halbert, G W. N1 - Copyright © 2012 Elsevier B.V. All rights reserved.. PY - 2012/4/15. Y1 - 2012/4/15. N2 - The novel organoarsenical GSAO, 4-(N-(S-glutathionylacetyl)amino) phenylarsonous acid, has potential anti-angiogenic capability with application in cancer where tumour metastasis relies on neo-vascularisation. As GSAO arsenic is trivalent, the arsenoxide moiety reacts with appropriately spaced cysteine residues on adenine nucleotide translocase (ANT) mitochondrial membrane protein. Molecular oxidation of the arsenic to the pentavalent structure, as in the degradant GSAA (4-(N-(S-glutathionylacetyl)amino) phenylarsonic acid), prevents sulphydryl interaction and risks abolition of activity. We report here on formulation studies aiming to produce a parenteral ...
FROM JOURNAL OF CLINICAL ONCOLOGY. The combination of all-trans--retinoic acid (ATRA) and arsenic trioxide continues to show advantages over ATRA and chemotherapy as first-line therapy for patients with low- or intermediate-risk acute promyelocytic leukemia (APL), investigators report.. The final analysis of the APL046 study , a noninferiority trial of ATRA plus arsenic trioxide (ATRA-ATO) vs. ATRA and standard chemotherapy, showed that event-free survival (EFS) and overall survival (OS) were significantly better among patients assigned to ATRA-ATO. Patients in this group also had a significantly lower cumulative incidence of relapse, reported Francesco Lo-Coco, MD, of University Tor Vergata in Rome and colleagues.. Our results support the use of ATRA-ATO in patients with newly diagnosed APL and point to this strategy as the new standard of care for low- or intermediate-risk patients. Studies exploring the role of ATRA-ATO are warranted in other APL subsets including high-risk, pediatric, and ...
