UVB activates ERK1/2 and p38 signaling pathways via reactive oxygen species in cultured keratinocytes. (1/170)

We have previously shown that hydrogen peroxide is an important mediator of ultraviolet B induced phosphorylation of the epidermal growth factor receptor in human keratinocytes. Here we demonstrate that physiologic doses of ultraviolet B and hydrogen peroxide stimulate activation of two related but distinct mitogen-activated protein kinase pathways: extracellular regulated kinase 1 and 2 (ERK1/2), as well as p38, the mammalian homolog of HOG1 in yeast which is a major kinase for a recently identified stress-induced signaling pathway. The time-dependent activation of ERK1/2 and p38 are distinct, and ultraviolet B-induced ERK1/2 activation is downregulated more rapidly than p38. Using dihydrorhodamine or Amplex as specific fluorescent dye probes, we show that ultraviolet B-induced peroxides can be inhibited by ascorbic acid. Ascorbic acid strongly blocks ERK1/2 and p38 activation by ultraviolet B and hydrogen peroxide whereas pyrrolidine dithiocarbamate and butyl hydroxyanisole are less effective. Pyrrolidine dithiocarbamate was unable to inhibit ultraviolet B-induced p38 activation. Cell death was increased after ultraviolet B when ERK1/2 activation was attenuated by the specific inhibitor PD098059. The distinct time courses and extents of activation and inhibition of ERK1/2 and p38 indicate that these pathways are separate and regulated independently in keratinocytes. Specific types of reactive oxygen species induced by ultraviolet B as well as selective activation or inhibition of specific phosphatases may mediate these responses in keratinocytes. These findings demonstrate that reactive oxygen species are important multifunctional mediators of ultraviolet B-induced ERK1/2 and p38 signaling transduction pathways and suggest that ERK1/2 may play an important part in protecting keratinocytes from cell death following oxidative stress.  (+info)

Patterns of DNA adduct formation in liver and mammary epithelial cells of rats treated with 7,12-dimethylbenz(a)anthracene, and selective effects of chemopreventive agents. (2/170)

7,12-Dimethylbenz(a)anthracene (DMBA) is a prototype carcinogen that induces a high yield of mammary tumors in rats after a single feeding. We investigated the induction and chemoprevention of DNA adducts in female Sprague Dawley rats receiving DMBA by gavage according to a variety of treatment schedules. The patterns of 32P-postlabeled DNA adducts in liver and mammary epithelial cells were similar to those produced by the in vitro reaction of metabolically activated DMBA with calf thymus DNA. There was a high and statistically significant correlation between dose of DMBA administered to rats (0, 0.6, 2.4, and 12 mg/kg body weight) and levels of DNA adducts in both types of cells. The regression lines relating DMBA doses to total DNA adduct levels were significantly divergent and crossed at 1.5 mg/kg body weight, indicating that, at lower doses, the formation of DNA adducts is more intense in target mammary cells, whereas at higher doses, DNA adduct levels are more elevated in liver cells, presumably due to the greater metabolic capacity of this organ. When the rats were sacrificed 7 days rather than 2 days after DMBA administration, DNA adduct levels were approximately halved in both liver and mammary cells. The observed patterns can be interpreted based on toxicokinetic factors, local and distant metabolism, removal of DNA adducts by excision repair, and cell proliferation rate. Of three chemopreventive agents given with the diet to rats treated with 12 mg of DMBA, 5,6-benzoflavone (1650 ppm) was the most effective, inhibiting DNA adduct formation in liver and mammary cells by 96.5 and 83.5%, respectively. Feeding of 1,2-dithiole-3-thione (600 ppm) inhibited this biomarker by 68.5 and 50.2%, whereas butyl hydroxyanisole (BHA; 5000 ppm) showed a significant inhibition in the liver (46.5%) but was ineffective in mammary cells (29.0%, not significant). These data correlate nicely with the results of a parallel study in which 5,6-benzoflavone, 1,2-dithiole-3-thione, and BHA inhibited formation of hemoglobin adducts by 80.0, 44.0, and 0%, respectively; the incidence of mammary tumors by 82.4, 47.1, and 5.9%, respectively; and their multiplicity by 92.6, 80.0, and 7.4%, respectively. Therefore, biomarkers of biologically effective dose are highly predictive of the efficacy of chemopreventive agents in the DMBA rat mammary model. The selective inhibition by BHA of DNA adducts in the liver but not in mammary cells is consistent with the finding that this phenolic antioxidant stimulated phase II activities in the liver but not in the mammary gland (L. L. Song et al., manuscript in preparation). In any case, the broad-spectrum inducer 5,6-BF appears to be more effective than the two monofunctional phase II inducers, presumably because an enhanced activation of DMBA to reactive metabolites is coordinated with their blocking, detoxification, and excretion.  (+info)

Effects of butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) on the acetylation of 2-aminofluorene and DNA-2-aminofluorene adducts in the rat. (3/170)

The effects of the synthetic phenolic antioxidants (butylated hydroxyanisole and butylated hydroxytoluene) on the in vivo acetylation of 2-aminofluorene and formation of DNA-2-aminofluorene adducts were investigated in male Sprague-Dawley rats. For in vitro examination, cytosols and intact cells, with or without butylated hydroxyanisole and butylated hydroxytoluene co-treatment, showed different percentages of 2-aminofluorene acetylation and DNA-2-aminofluorene adducts. For in vivo examination, pre-treatment of male rats with butylated hydroxyanisole and butylated hydroxytoluene (10 mg/kg) 48 h prior to the administration of 2-aminofluorene (50 mg/kg) resulted in 34% and 18%, 29% and 20% decreases, respectively, in the urinary and fecal recovery of N-acetyl-2-aminofluorene, and 34% and 19% decreases, respectively, in the metabolic clearance of 2-aminofluorene to N-acetyl-2-aminofluorene. Following exposure of rats to the 2-aminofluorene, with or without pretreatment with butylated hydroxyanisole and butylated hydroxytoluene, DNA-2-aminofluorene adducts were observed in the target tissues of liver and bladder, and also in circulating leukocytes. The DNA-2-aminofluorene adducts in liver, bladder, and leukocytes were decreased by pretreatment with butylated hydroxyanisole and butylated hydroxytoluene. This is the first demonstration that synthetic phenolic antioxidants decrease the N-acetylation of carcinogens and formation of DNA-carcinogen adducts in vivo.  (+info)

Specificity of endogenous fatty acid release during tumor necrosis factor-induced apoptosis in WEHI 164 fibrosarcoma cells. (4/170)

Recombinant tumor necrosis factor alpha (rTNF-alpha)-induced release of endogenous fatty acids was examined in WEHI 164 clone 13 fibrosarcoma cells using a highly sensitive HPLC method. The initial rTNF-alpha-induced extracellular release of endogenous fatty acids was dominated by 20:4n;-6, 22:4n;-6, 24:4n;-6, and 18:1n;-9 showing relative rates of 2.9, 0.9, 1.1, and 1.0, respectively. Release of endogenous AA and DNA fragmentation occurred simultaneously and preceded cell death by approx. 2 h. Methyl arachidonoyl fluorophosphonate and LY311727, specific inhibitors of Ca(2+)-dependent cytosolic PLA(2) (cPLA(2)) and secretory PLA(2) (sPLA(2)), respectively, neither blocked rTNF-alpha-induced cytotoxicity or endogenous AA release. However, both inhibitors reduced rTNF-alpha-induced release of other endogenous fatty acids. In comparison, the antioxidant butylated hydroxyanisole (BHA) completely inhibited the rTNF-alpha-induced cytotoxicity as well as AA release mediated through the TNF receptor p55, while the very similar antioxidant butylated hydroxytoluene had no effect. BHA did not inhibit recombinant cPLA(2) or sPLA(2) enzyme activity in vitro. Furthermore, stimulation of cells with rTNF-alpha for 4 h did not increase cPLA(2) enzyme activity. The data indicate that neither cPLA(2) or sPLA(2) mediate rTNF-alpha-induced apoptosis and extracellular AA release in WEHI cells. The results suggest that a BHA-sensitive signaling pathway coupled to AA release is a key event in TNF-induced cytotoxicity in these cells.  (+info)

p38 mitogen-activated protein kinase negatively regulates the induction of phase II drug-metabolizing enzymes that detoxify carcinogens. (5/170)

Phase II drug-metabolizing enzymes, such as glutathione S-transferase and quinone reductase, play an important role in the detoxification of chemical carcinogens. The induction of these detoxifying enzymes by a variety of agents occurs at the transcriptional level and is regulated by a cis-acting element, called the antioxidant response element (ARE) or electrophile-response element. In this study, we identified a signaling kinase pathway that negatively regulates ARE-mediated gene expression. Treatment of human hepatoma HepG2 and murine hepatoma Hepa1c1c7 cells with tert-butylhydroquinone (tBHQ) stimulated the activity of p38, a member of mitogen-activated protein kinase family. Inhibition of p38 activation by its inhibitor, SB203580, enhanced the induction of quinone reductase activity and the activation of ARE reporter gene by tBHQ. In contrast, SB202474, a negative analog of SB203580, had little effect. Consistent with this result, interfering with the p38 kinase pathway by overexpression of a dominant-negative mutant of p38 or MKK3, an immediate upstream regulator of p38, potentiated the activation of the ARE reporter gene by tBHQ, whereas the wild types of p38 and MKK3 diminished such activation. In addition, inhibition of p38 activity augmented the induction of ARE reporter gene activity by tert-butylhydroxyanisole, sulforaphane, and beta-naphthoflavone. Thus, p38 kinase pathway functions as a negative regulator in the ARE-mediated induction of phase II detoxifying enzymes.  (+info)

Examination of selected food additives and organochlorine food contaminants for androgenic activity in vitro. (6/170)

In order to produce a reporter gene assay for androgenic chemicals, a constitutive expression vector coding for the human androgen receptor and a reporter construct containing the firefly luciferase coding sequence under transcriptional control of the androgen responsive MMTV promoter were cotransfected into the androgen-insensitive human PC-3 prostate carcinoma cell line and stable transfectants selected. One colony of transfectants, PC-3 LUCAR+, was characterized further. 5alpha-Dihydrotestosterone (DHT) enhanced luciferase activity in a linear fashion for up to 3 days of culture. The Kd for DHT activation was within the range of 25.0-60.0 pM (r2 values >0.95). Flutamide competitively inhibited DHT activation (mean Ki value of 0.89 microM). Progesterone, estradiol, dexamethasone, and hydrocortisone were weak agonists (100-fold less effective than DHT) and diethylstilbestrol was without effect. The effects of organochlorine food contaminants (0, 0.1, 1.0, and 10.0 microM) on luciferase activity in PC-3 LUCAR+ cells were determined after exposure to the chemical for 18 h in the presence and absence of DHT (50 pM). 1,1-dichloro-2,2-bis(p-chlorophenyl)-ethylene (p,p'-DDE) induced luciferase activity in the absence of DHT (100 microM p,p'-DDE equivalent to 50 pM DHT), but in the presence of DHT (50 pM), p,p'-DDE acted antagonistically. 2,3,7,8-Tetrachlorodibenzo-p-dioxin, kepone, butylated hydroxyanisole, and butylated hydroxytoluene all partially inhibited activation by DHT (50 pM) but alone had little or no effect. Toxaphene at 10 microM induced luciferase activity in the absence of DHT but decreased cell viability. Alpha- and delta-Hexachlorocyclohexanes (HCH) at 10 microM antagonized the DHT effect, but beta-HCH and gamma-HCH mirex, photomirex, oxychlordane, cis- and trans-nonachlor were without effect. Thus, of the chemicals tested, some interact with the human androgen receptor in vitro as agonists, others as antagonists, and some as partial agonists/antagonists.  (+info)

Modulation of the phosphatase activity of calcineurin by oxidants and antioxidants in vitro. (7/170)

Previous research has indicated that oxidants, antioxidants and the intracellular redox state regulate the activities of a variety of protein tyrosine kinases, protein tyrosine phosphatases, phospholipases and transcription factors. In order to explore the redox regulation of the serine/threonine phosphatase calcineurin, we have investigated the effects of a variety of oxidants and antioxidants on calcineurin phosphatase activity in vitro. The oxidants hydrogen peroxide, superoxide and glutathione disulfide inhibited the phosphatase activity of calcineurin in a dose-dependent manner. Incubation of purified calcineurin with the antioxidants ascorbate, ascorbate 2-phosphate, alpha-lipoic acid, N-acetyl-L-cysteine and glutathione increased phosphatase activity relative to untreated controls. In contrast, several other commonly used antioxidants, including butylated hydroxytoluene, butylated hydroxyanisole, TEMPOL (4-hydroxy-2,2,6, 6-tetramethylpiperidine-N-oxyl), Trolox (6-hydroxy-2,5,7, 8-tetramethyl-chroman-2-carboxylic acid) and dihydrolipoic acid decreased the activity of purified calcineurin, possibly through prooxidative mechanisms. Although the antioxidant pyrrolidine dithiocarbamate increased the activity of purified calcineurin, it significantly inhibited the activity of calcineurin present in crude fibroblast lysates. These results support and extend the hypothesis that redox factors modulate the phosphatase activity of calcineurin and suggest that further in vivo studies are warranted.  (+info)

Induction of murine intestinal and hepatic peroxiredoxin MSP23 by dietary butylated hydroxyanisole. (8/170)

Feeding mice with 2(3)-t-butyl-4-hydroxyanisole (BHA) induces phase II detoxifying enzymes that inhibit the action of carcinogens. We have found that dietary BHA induces intestinal and hepatic MSP23 (also called peroxiredoxin I), a stress-inducible antioxidant, in a manner similar to the induction of glutathione S-transferases (GSTs). The levels of MSP23 in the proximal intestine and liver, estimated by immunoblotting, increased approximately 1.9- and 1.3-fold, respectively, in mice fed a diet containing 0.7% (w/w) BHA for 7 days. The level of MSP23 mRNA in these tissues also increased more than 2-fold after mice were fed BHA, suggesting that the induction of MSP23 is controlled at the transcription level. Immunostaining of the small intestine shows that MSP23 is expressed mainly in the columnar epithelial cells. The induction of MSP23 may be important to protect the cells and tissues against toxic electrophiles and reactive oxygen species.  (+info)

Summary The Global Butyl Hydroxyanisole Industry 2017 Market Research Report is a professional and in-depth study on the current state of the Butyl Hydroxy
Butylated hydroxyanisole (BHA) is a commonly used food additive with demonstrated inhibitory action against chemical carcinogenesis in animals. In order to elucidate the mechanism of the anticarcinogenic action, the effects of BHA on benzo(a)pyrene (BP) metabolism were studied with lung microsomes from female mice. BHA treatment (0.5% in the diet for 7 days) inhibited BP metabolism and altered the ratios among different metabolites as analyzed by high-performance liquid chromatography. The treatment reduced the metabolic formation of 9,10-dihydroxy-9,10-dihydrobenzo(a)pyrene, but not the production of 3-hydroxybenzo(a)pyrene and trans-4,5-dihydroxy-4,5-dihydrobenzo(a)pyrene. Since the gross microsomal cytochrome P-450 content was not significantly affected by the treatment, the change of regioselectivity in BP metabolism was probably due to the alteration of cytochrome P-450 isozyme composition by dietary BHA. General and regioselective inhibition of BP metabolism was also observed when BHA was ...

Recently, copper has been shown to be capable of mediating the activation of several xenobiotics producing reactive oxygen and other radicals. Since copper exists in the nucleus and is closely associated with chromosomes and DNA bases, in this study we have investigated whether the activation of 1,4-hydroquinone (1,4-HQ) and a variety of other phenolic compounds by copper can induce strand breaks in double-stranded φX-174 RF I DNA (φX-174 relaxed form I DNA). In the presence of micromolar concentrations of Cu(II), DNA strand breaks were induced by 1,4-HQ and other phenolic compounds including 4,4′-biphenol, catechol, 1,2,4-benzenetriol, 2-methoxyestradiol, 2-hydroxyestradiol, diethylstilbestrol, butylated hydroxytoluene, butylated hydroxyanisole, tert-butylhydroquinone, ferulic acid, caffeic acid, chlorogenic acid, eugenol, 2-acetamidophenol, and acetaminophen. Structure-activity analysis shows that in the presence of Cu(II), the DNA cleaving activity for phenolic compounds with a ...
Rocaltrol (calcitriol) is a synthetic vitamin D analog which is active in the regulation of the absorption of calcium from the gastrointestinal tract and its utilization in the body. All dosage forms contain butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) as antioxidants. The capsules contain a fractionated triglyceride of coconut oil, and the oral solution contains a fractionated triglyceride of palm seed oil. Gelatin capsule shells contain glycerin, parabens (methyl and propyl) and sorbitol. The two known sites of action of calcitriol are intestine and bone. A calcitriol receptor-binding protein appears to exist in the mucosa of human intestine. Additional evidence suggests that calcitriol may also act on the kidney and the parathyroid glands. Calcitriol is the most active known form of vitamin D3 in stimulating intestinal calcium transport. In acutely uremic rats calcitriol has been shown to stimulate intestinal calcium absorption. The kidneys of uremic patients cannot ...

Established Fa32 cells, derived from a rat hepatoma, were investigated for their glutathione S-transferase (GST) induction capacity, which is an important characteristic of the detoxification capacity in normal liver. The cells were exposed to inducers of drug metabolism for 3 days in complete medium (containing 10% fetal calf serum). Neither dimethyl sulphoxide nor dimethyl formamide could be used as a vehicle to transport the inducers into the cells, because they also interacted with GST. Phenobarbital, butylated hydroxyanisole, allyl isothiocyanate and dimethyl fumarate (but not fumaric acid) all effectively increased the total specific GST activity. None of the test chemicals produced a very pronounced induction of specific GST subunits, but subunit 2 and subunit 8 were increased more than the others. The effects of inducers of drug metabolism on the GST activity in Fa32 cells are comparable with those in rat liver. These cells can therefore be used as a valuable alternative model for ...

A P P L I C AT I O N N O T E Liquid Chromatography Author: Wilhad M. Reuter PerkinElmer, Inc. Shelton, CT Analysis of Phenolic Antioxidants in Edible Oil/Shortening Using the PerkinElmer Altus UPLC System with PDA Detection Introduction Phenolic antioxidants are commonly used in food to prevent the oxidation of oils. Oxidized oil and fats cause foul odor and rancidity in food products, which is a major cause for concern to the food industry. Globally, regulations vary, but current maximum allowable levels are as low as 100 µg/g (100 ppm). This application note presents a UHPLC method for the analysis of the ten most common phenolic antioxidants that may be found in such products. The application was carried out with minor modifications to the AOAC Official Method 983.15 (1). This method applies to the analysis of finished food products. A 2.7-μm SPP (superficially porous particle) C18 column was used, allowing one to achieve very high throughput at a back-pressure considerably lower than that ...
Emerging contaminants (ECs) are chemicals that are currently unregulated due to limited understanding of health effects and limited data regarding occurrence. Wastewater treatment plants (WWTP) receive many ECs as components of influent waste and the removal of organic contaminants, such as ECs, occurs primarily by sorption to sludge. Therefore, it is important to develop measures of sorption behavior by ECs to sludge. This study evaluates sorption of three ECs: 3-tert-butyl-4-hydroxyanisole (BHA) a synthetic antioxidant, 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethyl-cyclopenta(g)-2-benzopyrane (HHCB) a polycyclic musk, and chlorpyrifos a organophosphate insecticide.. Twenty-four hour laboratory-scale sorption experiments were conducted for each compound individually and then in combination, which allowed the quantification of sorption onto wastewater sludge and the affects of multiple compounds. ECs in both the liquid and solid phases were analyzed using a gas chromatograph with flame ionization ...

In the present study, seven hydroxamic acid derivatives of nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, fenoprofen, ketoprofen, indomethacin and diclofenac) were found to possess significant antioxidant, radical scavenging and metal chelating activities. The most active antioxidant and radical scavenger was N-methylhydroxamic acid of diclofenac (ANT = 88.0 % and EC50 = 60.1 microg mL-1). The activity of the standard substance, butylated hydroxyanisole, in the two assays was ANT = 86.9 % and EC50 = 18.8 microg mL-1, respectively. Ibuproxam was the strongest iron chelator among investigated hydroxamic acids (EC50 = 255.6 microg mL-1), yet significantly weaker than the standard substance, EDTA (EC50 = 29.1 microg mL-1). It seems that different mechanism is involved in metal chelating activity than in antioxidant and radical scavenging activity. Antioxidant and radical scavenging activities may be connected with conjugation of the nitrogen lone electron pair with the ...
Fatty acid hydroperoxide lyase (HPO-lyase) was purified 300-fold from tomatoes. The enzymatic activity appeared to be very unstable, but addition of Triton X100 and beta-mercaptoethanol to the buffer yielded an active enzyme that could be stored for several months at −80°C. The enzyme was inhibited by desferoxamine mesylate (desferal), 2-methyl-1,2-di-3-pyridyl-1-propanone ... read more (metyrapone), nordihydroguaiaretic acid (NDGA), n-propyl gallate and butylated hydroxyanisole, suggesting the involvement of free radicals in the reaction mechanism and the existence of a prosthetic group in the active center. However, no heme group could be demonstrated with the methods commonly used to identify heme groups in proteins. Only 13-hydroperoxides from linoleic acid (13-HPOD) and alpha-linolenic acid (alpha-13-HPOT) were cleaved by the tomato enzyme, with a clear preference for the latter substrate. The pH-optimum was 6.5, and for concentrations lower than 300 mu M a typical Michaelis Menten curve ...
Infusion of menadione at two different doses [2.7 mg and 5.5 mg in 100 microliters of dimethyl sulphoxide (DMSO)] into perfused rat livers for 30 min caused no or a 6-fold increase respectively in junctional permeability to horseradish peroxidase as compared with controls receiving 100 microliters of DMSO alone. The total glutathione (GSH) contents in these livers measured at the end of the experiments were 115% and 53%, compared with the controls. The free-radical scavenger butylated hydroxytoluene (BHT) (final concn. 5 microM) protected against the GSH depletion caused by the higher dose of menadione and partially decreased the menadione-induced increase in junctional permeability. Verapamil, a Ca2(+)-channel blocker which was added into the perfusion medium (final concn. 40 microM) 10 min before the infusion of 5.5 mg of menadione, completely abolished the effect of menadione on junctional permeability. Menadione exposure therefore increases tight-junctional permeability in the liver; this ...
Abstract : The antioxidants play an important role in the preservation of foods and the management of oxidative stress relateddiseases by acting on reactive oxygen species and free radicals. However, their use in high temperature processed food andpharmaceuticals are limited due to its low thermal stability. The objective of the study was to use the biofield energy treatment onbutylated hydroxytoluene (BHT) i.e. antioxidant and analyse its impact on the physical, thermal, and spectral properties of BHT.For the study, the sample was divided into two groups and termed as control and treated. The treated group was subjected tobiofield energy treatment. The characterization of treated sample was done using X-ray diffraction (XRD), differential scanningcalorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) and UV-visible (UV-Vis) spectroscopy.The XRD results showed the alteration in lattice parameters, unit cell volume, and molecular weight along with 14.8% reduction ...

However, the FDA allows BHA to be added to human food (and dog treats) at certain levels and classifies the preservative as "generally regarded as safe." The idea is that although BHA might cause cancer in lab rats, its metabolized differently by other animals -humans and dogs in particular - and its used in foods at amounts well below levels that would cause problems. Still, the :Check the kind of preservative used in your pets food. While most manufacturers have switched to natural preservatives like vitamin C, vitamin E or tocopherols, some foods and treats still use chemical preservatives, including BHA, BHT and ethoxyquin. Whole Dog Journal notes that BHA and BHT have been linked to cancer in laboratory animals, though its unknown whether they are equally carcinogenic in people and pets. The publication also points out that manufacturers have favored artificial preservatives because they preserve food longer and are cheaper. If you choose naturally preserved food, be ready to pay a bit ...

I think you have made a compelling argument for dissolving the BHT into an oil. I do remember that BHT takes a long time to dissolve when the oil isn t hot (but it does dissolve eventually). I never tried dissolving BHT into hot oil. But it follows that absorption would be enhanced were the BHT dissolved when ingested. Theoretically, one could heat enough oil add the right amount of BHT so that one wouldn t need to make the cocktail everytime a dose was administered. I do believe that the BHT would dissolve even without heat, but I don t know how long it would take. Also, I would nee ...

Human epidemiological and laboratory animal model studies have suggested that nonsteroidal antiinflammatory drugs reduce the risk of development of colon cancer and that the inhibition of colon carcinogenesis is mediated through the alteration in cyclooxygenase metabolism of arachidonic acid. Curcumin, which is a naturally occurring compound, is present in turmeric, possesses both antiinflammatory and antioxidant properties, and has been tested for its chemopreventive properties in skin and forestomach carcinogenesis. The present study was designed to investigate the chemopreventive action of dietary curcumin on azozymethane induced colon carcinogenesis and also the modulating effect of this agent on the colonic mucosal and tumor phospholipase A2, phospholipaseC1, lipoxygenase, and cyclooxygenase activities in male F344rats. At 5 weeks of age, groups of animals were fed the control(modified AIN-76A) diet or a diet containing 2000 ppm of curcumin.At 7 weeks of age, all animals, except those in ...

Within the functional group of transcriptional regulation, we find the transcription factor Fosl2 (also known as Fra2), a Fos family member, among the most prominently up-regulated by both chemopreventive compounds. Interestingly, an antitumor promoter, the phenolic antioxidant tert-butylhydroquinone, was reported to induce expression of Fra2 (Fosl2) as well as Fra1. Furthermore, the authors concluded that inhibitory activator protein-1 complexes composed of Jun-Fra heterodimers, induced by tert-butylhydroquinone, antagonize the transcriptional effects of the tumor promoter 12-O-tetradecanoylphorbol-13-acetate, which are mediated by Jun-Fos heterodimers (21). Similarly, inhibition of interleukin-6-stimulated cell growth of human myeloma and mouse hybridoma cells was shown to be associated with increased expression of Fra2 protein (22). Fra2 has also been associated with differentiation in epidermis, and exogenous expression of Fra-2 (Fosl2) repressed activator protein-1 transcriptional activity ...
Nrf2 (Nfe2l2) Knockout mice. This strain is a useful model for the in vivo analysis of chemical carcinogenesis and resistance to anti-cancer drugs. A phenolic antioxidant significantly induced the expression of phase II enzymes such as glutathione S-transferase and NAD(P)H: quinone oxidoreductase in normal mice. However, in the homozygous Nrf2 deficient mice the induction of the phase II enzymes by a phenolic antioxidant was largely eliminated in the liver and intestine. Since Nrf2 is constantly degraded by proteasome under normal condition, it is hardly to detect Nrf2 protein in the absence of stimuli. Electrophilic chemicals, such as DEM (diethyl maleate) and tBHQ (tert-buthyl hydroquinone), are generally used to stabilize Nrf2. Or proteasomal inhibitors, such as MG132, are also effective increasing the protein amount of Nrf2.

The effects of four calcium channel blockers (nicardipine, nifedipine, verapamil, and diltiazem) on free radical injury in cultured endothelial cells were studied and compared with those of butylated hydroxytoluene. When the cultured cells were exposed to a superoxide and hydroxyl radical generating system for up to 60 minutes, lipid peroxidation occurred, and cellular viability decreased by 60% at 30 minutes. Concomitantly, total cellular glutathione decreased by 40%, whereas total protein thiols changed minimally. Preincubation of the cells with each of the calcium blockers (5 and 20 microM) before free radical addition resulted in various degrees of significant protection against cell death, and losses of glutathione correlated significantly (r = 0.89, p less than 0.001). The order of efficacy was nicardipine greater than nifedipine greater than verapamil greater than diltiazem; butylated hydroxytoluene was about fourfold more potent than nicardipine. Because none of the agents affected the ...

The effects of phenobarbital (PB) and other liver monooxygenase modifiers on dimethylnitrosamine (DMN)-induced alkylation of rat liver DNA and protein were investigated at different carcinogen doses. In rats given single injections of radioactively labeled DMN, pretreatment with PB (80 mg/kg body weight, administered for 5 days) resulted in a small but significant decrease in the formation of 7-methylguanine and O6-methylguanine per mole of guanine in liver DNA associated with a decrease in the O6/N7-methylguanine ratio. The specific radioactivity of liver protein was also lowered in PB-pretreated rats. The degree of PB interference was independent of DMN dose within a carcinogen dose range of 0.5 µg to 10 mg/kg body weight. In parallel experiments, the effects of pretreatment with PB, Aroclor 1254, pregnenolone-16α-carbonitrile, butylated hydroxytoluene, β-naphthoflavone, and ethanol on DMN-induced alkylation of liver DNA were studied at a DMN dose of 5 µg/kg body weight. In general, ...

0067]Polymerisations were carried out in an oil bath in a 100 ml round bottom glass vessel with mechanical stirring and under nitrogen atmosphere. Monomer and other starting chemicals, such as DL-α-tocopherol (0.01 wt-%), vinyl comonomer (e.g tetramethyltetraviniylcycloterasiloxane (MV4), 0.01 mol-%) or vinyl copolymer and end blocker (e.g. tetramethyl divinyl disiloxane) were introduced to the vessel. Through changing the stoichiometry starting chemicals with each other the molecular weight of the polymer and crosslinking density of the prepared elastomer could be varied. Polymerisation temperature was 150° C. and mixing rather vigorous (200-400 rpm). When the temperature of the reaction solution reached 150° C., 50 ppm of catalyst 1-tert-butyl-4,4,4-tris(dimethylamino)-2,2-bis[tris(dimethylamino)-phosph- oranylidenamino]-2Δ5,4Δ5-catenadi(phosphazene) was added with microsyringe through the septum below the surface of the solution.

Virgin olive oil is slightly more acidic than extra virgin olive oil. Virgin olive oils may not meet the high flavor, aroma, and color standards of extra virgin olive oils, but they can still be very nice quality oils. You can expect to pay less for virgin olive oils. As you might suspect by now, the top rank of olive oil is somewhat subjective. Even among top rated extra virgin olive oils there can be considerable differences - some can have very strong pungent peppery qualities, while others can be very fruity.. Richard Gawel, an internationally known olive oil consultant and olive oil judge describes refined olive oil:. "Pure,light and those simply labelled as olive oil are those which have been refined. Refining is a complex process that involves the use of acids, alkalis, steam and other deodorising agents. The refining process removes all of the aroma and flavour substances out of olive including its natural antioxidants. Artificial antioxidants such as butylated hydroxyanisole (BHA) ...
I mentioned before in my previous post that the C20 serum is my all-time favorite product, but I think Ive finally moved on and found a new life-saver. From my first try, I could tell that the Blackhead Power liquid delivered all the things it promised-hyperpgmentation, blackheads, whiteheads, closed comedos, and just the overall texture of my skin. While greatly reduced, I still usually had at least 1 or 2 outbreaks every week when using the C20 serum, but with the BHA liquid, that numbers changed to about 1-2 a month! Another thing I love is how non-irritatable it is to the skin. My skin doesnt tingle or sting when applying the BHA.. Yet another plus- if youre on a tight budget, this definetely will work for your skin and you wallet. For around 18 dollars you get 100ml of product. Trust me-this lasts forever. Ive had mine for about 1 month, and it barely looks like anythings been tapped out!. Rating(Out of 5): 5. This is my new favorite product that Ill be shoving into all my acne-prone ...
ESR is an invaluable tool for elucidating free radical reaction mechanisms. Although there are many radicals that live long enough to be observed directly with ESR, many important radicals, such as hydroxyl, superoxide, methyl, and other important organic intermediates, are too short lived to be observed directly. These very short lived radicals can often be observed by a technique called spin trapping. There are many things which must be considered when choosing a spin trap, fromthe role the solvent may play to possible side reactions that create unexpected stable spin adducts- one of the pitfalls of spin-trapping. In this laboratory exercise, students are able to observe the formation of three different radical adducts using a Fenton reaction in DMSO using PBN (t-butyl-α-phenyl nitrone). It takes about fifteen minutes for the third radical to become well established. The reaction can be observed in real time. ...
In spite of the major role played by cigarette smoking in the epidemiology of lung cancer, it is very difficult to reproduce the carcinogenicity of this complex mixture in animal models. We implemented a series of pilot experiments in three mouse strains, exposed either to environmental cigarette smoke (ECS) or mainstream cigarette smoke (MCS) or its condensate (MCSC). The whole-body exposure of Aroclor-treated A/J mice to ECS resulted in a rapid and potent induction of micronuclei in peripheral blood erythrocytes. After 6 months of exposure, 6 h a day, followed by 4 months of recovery in filtered air, both lung tumor incidence and multiplicity were significantly increased as compared to sham-exposed mice (77.8% vs. 22.2%, and 1.11±0.26 vs. 0.22±0.15, means ± SE). Multiple i.p. injections of butylated hydroxytoluene did not significantly enhance the tumor yield. Another experiment confirmed the responsiveness of A/J mice exposed to ECS for 5 months, followed by 4 months of recovery in air ...

  • Butylated hydroxyanisole was studied in mice and rats for its ability to modify the carcinogenicity of selected chemical agents. (inchem.org)
  • Butylated hydroxyanisole administered to rats at maternally toxic and occasionally lethal doses during, or before, during and after, gestation induced slight embryotoxicity but no definite indication of teratogenicity. (inchem.org)
  • In rats, feeding of butylated hydroxyanisole in the diet caused superficial necrosis, ulceration and hyperplasia of the squamous epithelium of the forestomach. (inchem.org)
  • Administration of butylated hydroxyanisole by gavage to monkeys was associated with an elevated mitotic index in the squamous epithelium of the distal oesophagus. (inchem.org)
  • Butylated hydroxyanisole was not mutagenic to Salmonella typhimurium , Drosophila melanogaster or to Chinese hamster cells in vitro . (inchem.org)
  • When tested in combination with other chemicals (usually known mutagens or carcinogens), butylated hydroxyanisole often modified their DNA damaging, mutagenic and clastogenic activities. (inchem.org)
  • Butylated Hydroxyanisole is used as a sulfonamide bacteriostatic antibiotic in combination with trimethoprim as the drug Bactrim. (shreejiexports.net)
