Polycyclic Hydrocarbons, Aromatic
A major group of unsaturated cyclic hydrocarbons containing two or more rings. The vast number of compounds of this important group, derived chiefly from petroleum and coal tar, are rather highly reactive and chemically versatile. The name is due to the strong and not unpleasant odor characteristic of most substances of this nature. (From Hawley's Condensed Chemical Dictionary, 12th ed, p96)
Receptors, Aryl Hydrocarbon
Cytoplasmic proteins that bind certain aryl hydrocarbons, translocate to the nucleus, and activate transcription of particular DNA segments. AH receptors are identified by their high-affinity binding to several carcinogenic or teratogenic environmental chemicals including polycyclic aromatic hydrocarbons found in cigarette smoke and smog, heterocyclic amines found in cooked foods, and halogenated hydrocarbons including dioxins and polychlorinated biphenyls. No endogenous ligand has been identified, but an unknown natural messenger with a role in cell differentiation and development is suspected.
Water Pollutants, Chemical
The unstable triatomic form of oxygen, O3. It is a powerful oxidant that is produced for various chemical and industrial uses. Its production is also catalyzed in the ATMOSPHERE by ULTRAVIOLET RAY irradiation of oxygen or other ozone precursors such as VOLATILE ORGANIC COMPOUNDS and NITROGEN OXIDES. About 90% of the ozone in the atmosphere exists in the stratosphere (STRATOSPHERIC OZONE).
Cytochrome P-450 CYP1A1
A liver microsomal cytochrome P-450 monooxygenase capable of biotransforming xenobiotics such as polycyclic hydrocarbons and halogenated aromatic hydrocarbons into carcinogenic or mutagenic compounds. They have been found in mammals and fish. This enzyme, encoded by CYP1A1 gene, can be measured by using ethoxyresorufin as a substrate for the ethoxyresorufin O-deethylase activity.
Drug Administration Routes
An insecticide and herbicide that has also been used as a wood preservative. Pentachlorphenol is a widespread environmental pollutant. Both chronic and acute pentachlorophenol poisoning are medical concerns. The range of its biological actions is still being actively explored, but it is clearly a potent enzyme inhibitor and has been used as such as an experimental tool.
Halogenated Diphenyl Ethers
Nitrogen oxide (NO2). A highly poisonous gas. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death. (From Merck, 11th ed) It is a major atmospheric pollutant that is able to absorb UV light that does not reach the earth's surface.
Toxic, volatile, flammable liquid hydrocarbon byproduct of coal distillation. It is used as an industrial solvent in paints, varnishes, lacquer thinners, gasoline, etc. Benzene causes central nervous system damage acutely and bone marrow damage chronically and is carcinogenic. It was formerly used as parasiticide.
Exposure of the female parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. It includes pre-conception maternal exposure.
Exogenous agents, synthetic and naturally occurring, which are capable of disrupting the functions of the ENDOCRINE SYSTEM including the maintenance of HOMEOSTASIS and the regulation of developmental processes. Endocrine disruptors are compounds that can mimic HORMONES, or enhance or block the binding of hormones to their receptors, or otherwise lead to activating or inhibiting the endocrine signaling pathways and hormone metabolism.
A polychlorinated pesticide that is resistant to destruction by light and oxidation. Its unusual stability has resulted in difficulties in residue removal from water, soil, and foodstuffs. This substance may reasonably be anticipated to be a carcinogen: Fourth Annual Report on Carcinogens (NTP-85-002, 1985). (From Merck Index, 11th ed)
The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.
Cytochrome P-450 Enzyme System
A superfamily of hundreds of closely related HEMEPROTEINS found throughout the phylogenetic spectrum, from animals, plants, fungi, to bacteria. They include numerous complex monooxygenases (MIXED FUNCTION OXYGENASES). In animals, these P-450 enzymes serve two major functions: (1) biosynthesis of steroids, fatty acids, and bile acids; (2) metabolism of endogenous and a wide variety of exogenous substrates, such as toxins and drugs (BIOTRANSFORMATION). They are classified, according to their sequence similarities rather than functions, into CYP gene families (>40% homology) and subfamilies (>59% homology). For example, enzymes from the CYP1, CYP2, and CYP3 gene families are responsible for most drug metabolism.
A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.
The functional superiority and preferential use of one eye over the other. The term is usually applied to superiority in sighting (VISUAL PERCEPTION) or motor task but not difference in VISUAL ACUITY or dysfunction of one of the eyes. Ocular dominance can be modified by visual input and NEUROTROPHIC FACTORS.
Dose-Response Relationship, Drug
Any member of the class of enzymes that catalyze the cleavage of the substrate and the addition of water to the resulting molecules, e.g., ESTERASES, glycosidases (GLYCOSIDE HYDROLASES), lipases, NUCLEOTIDASES, peptidases (PEPTIDE HYDROLASES), and phosphatases (PHOSPHORIC MONOESTER HYDROLASES). EC 3.
Air Pollutants, Occupational
Aryl Hydrocarbon Hydroxylases
A large group of cytochrome P-450 (heme-thiolate) monooxygenases that complex with NAD(P)H-FLAVIN OXIDOREDUCTASE in numerous mixed-function oxidations of aromatic compounds. They catalyze hydroxylation of a broad spectrum of substrates and are important in the metabolism of steroids, drugs, and toxins such as PHENOBARBITAL, carcinogens, and insecticides.
Chromatography, High Pressure Liquid
Prenatal Exposure Delayed Effects
Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS.
Reactive Oxygen Species
Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include SINGLET OXYGEN; SUPEROXIDES; PEROXIDES; HYDROXYL RADICAL; and HYPOCHLOROUS ACID. They contribute to the microbicidal activity of PHAGOCYTES, regulation of signal transduction and gene expression, and the oxidative damage to NUCLEIC ACIDS; PROTEINS; and LIPIDS.
A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).
United States Environmental Protection Agency
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
Atmosphere Exposure Chambers
Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)
Gene Expression Regulation
The vapor state of matter; nonelastic fluids in which the molecules are in free movement and their mean positions far apart. Gases tend to expand indefinitely, to diffuse and mix readily with other gases, to have definite relations of volume, temperature, and pressure, and to condense or liquefy at low temperatures or under sufficient pressure. (Grant & Hackh's Chemical Dictionary, 5th ed)
Nitric acid (HNO3). A colorless liquid that is used in the manufacture of inorganic and organic nitrates and nitro compounds for fertilizers, dye intermediates, explosives, and many different organic chemicals. Continued exposure to vapor may cause chronic bronchitis; chemical pneumonitis may occur. (From Merck Index, 11th ed)
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Reverse Transcriptase Polymerase Chain Reaction
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
Biological Oxygen Demand Analysis
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
Maximum Allowable Concentration
The maximum exposure to a biologically active physical or chemical agent that is allowed during an 8-hour period (a workday) in a population of workers, or during a 24-hour period in the general population, which does not appear to cause appreciable harm, whether immediate or delayed for any period, in the target population. (From Lewis Dictionary of Toxicology, 1st ed)
Endocrine biomarkers of early fetal loss in cynomolgus macaques (Macaca fascicularis) following exposure to dioxin. (1/3283)This study examines the endocrine alterations associated with early fetal loss (EFL) induced by an environmental toxin, TCDD (2,3,7, 8-tetrachlorodibenzo-p-dioxin), in the cynomolgus macaque, a well-documented reproductive/developmental model for humans. Females were administered single doses of 1, 2, and 4 microgram/kg TCDD (n = 4 per dose group) on gestational day (GD) 12. Urinary estrogen metabolites (estrone conjugates) were monitored to establish the day of ovulation, and serum hormones (estradiol, progesterone, chorionic gonadotropin, relaxin) were measured to assess ovarian and placental endocrine status before and after treatment. EFL occurred between GDs 22 and 32 in 10 of the 12 animals treated with TCDD. The primary endocrine alterations associated with TCDD treatment were significant decreases in serum estradiol and bioactive chorionic gonadotropin concentrations (p < 0.02). Less pronounced decreases in serum progesterone (p = 0.10) and relaxin (p < 0.08) also followed TCDD treatment. In contrast, immunoreactive chorionic gonadotropin concentrations were not reduced by TCDD exposure at any level, indicating that TCDD targets specific components of the chorionic gonadotropin synthesis machinery within the trophoblast to alter the functional capacity of the hormone. These data demonstrate the value of endocrine biomarkers in identifying a toxic exposure to primate pregnancy many days before direct signs of reproductive toxicity were apparent. The increased EFL that occurred after exposure to TCDD might reflect a toxic response initially mediated via endocrine imbalance, leading to placental insufficiency, compromised embryonic circulation, and subsequent EFL.

Induction of hepatic cytochromes P450 in dogs exposed to a chronic low dose of polychlorinated biphenyls. (2/3283)Induction of cytochrome P450 isoforms, specifically CYP1A1, and their catalytic activities are potential biomarkers of environmental contamination by polychlorinated biphenyls (PCBs). In this study, dogs were exposed to 25 ppm or 5 ppm Aroclor 1248 (PCB mixture) daily in their diet for 10 or 20 weeks, respectively. Relative to controls, hepatic microsomes from dogs dosed with PCBs had higher levels of CYP1A1 detected in immunoblots and higher levels of EROD activity, but low levels of induction for CYP2B and PROD activity. Concentrations of 96 PCB congeners in serum and liver were evaluated using capillary chromatography. Results showed that all dogs exposed to PCB mixtures had higher levels of PCB in serum and liver. Dogs preferentially sequestered highly chlorinated PCB congeners in liver relative to serum. With these experiments, we demonstrated that EROD activity was a potentially sensitive marker of PCB exposure at 5 and 25 ppm. Furthermore, CYP1A1 and EROD activity were maximally induced in dogs consuming dietary concentrations only 2.5 times the maximal permissible level for human food (FDA). The value of CYP1A1 induction as a biomarker of PCB exposure was tenuous because neither CYP1A1 levels nor EROD activity correlated with total PCB body burden. However, a small subset of congeners were identified in liver that may strongly influence EROD and PROD induction. Finally, two dogs in the 25 ppm dose group were fasted for 48 h. After 24 h of fasting, several new congeners appeared in the serum and remained in the serum for the remainder of the fast. The fast caused a 293% increase in PCB concentration in serum. This increase has strong implications regarding mobilization of toxic PCBs in wildlife during fasting (e.g., migration, hibernation). (+info)
AhR, ARNT, and CYP1A1 mRNA quantitation in cultured human embryonic palates exposed to TCDD and comparison with mouse palate in vivo and in culture. (3/3283)2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is developmentally toxic in many species and induces cleft palate in the C57BL/6N mouse embryo. Palatogenesis in mouse and human embryos involves homologous processes at the morphological, cellular, and molecular levels. In organ culture, mouse and human palates respond similarly to TCDD. The present study quantitates the expression of AhR, ARNT, and CYP1A1 mRNA in human embryonic palates in organ culture. Palatal tissues were exposed to 1 x 10(-10), 1 x 10(-9), or 1 x 10(-8) M TCDD or control medium and sampled at 0, 2, 4, and 6 hours for quantitative RT-PCR using a synthetic RNA internal standard. Similar measurements of CYP1A1 gene expression were collected for mouse palates cultured in this model. In human palates, AhR expression correlated with ARNT and CYP1A1 mRNA expression. TCDD induction of CYP1A1 was time- and concentration-dependent. The expression of these genes presented a uniform and continuous distribution across the group of embryos, with no subset of either high or low expressors/responders. The ratio of AhR to ARNT was approximately 4:1. AhR mRNA increased during the culture period in both treated and control subjects; however, ARNT expression was relatively constant. TCDD did not alter either AhR or ARNT expression in a consistent dose- or time-related manner. Comparison of human and mouse data showed a high correlation across species for the induction of CYP1A1. Human embryos expressed approximately 350 times less AhR mRNA than the mouse, and in earlier studies it was shown that human palates required 200 times more TCDD to produce the same effects. When the morphological, cellular, and molecular responses to TCDD between mouse and human are compared, it seems highly unlikely that human embryos could be exposed to sufficient TCDD to achieve changes in palatal differentiation that would lead to cleft palate.

RT-PCR quantification of AHR, ARNT, GR, and CYP1A1 mRNA in craniofacial tissues of embryonic mice exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin and hydrocortisone. (4/3283)C57BL/6N mouse embryos exposed to hydrocortisone (HC) or 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) develop cleft palate. An interaction between these agents produces clefts at doses which alone are not teratogenic. The glucocorticoid receptor (GR) and dioxin receptor (AhR) mediated these responses and their gene expression was altered by TCDD and/or HC in palates examined on gestation day (GD) 14 by Northern blot analysis and in situ hybridization. The present study quantifies AhR, AhR nuclear translocator (ARNT), and GR mRNA at 4, 12, 24, and 48 h after exposure (time 0 = dose administration at 8 A.M. on gestation day 12) on GD12 to TCDD (24 micrograms/kg), HC (100 mg/kg) or HC (25 mg/kg) + TCDD (3 micrograms/kg). The induction of CYP1A1 mRNA was also quantified at 2, 4, 6, 12, 24, and 48 h for control and TCDD-exposed samples. Total RNA was prepared from midfacial tissue of 4-6 embryos/litter at each time and dose. An RNA internal standard (IS) for each gene was synthesized, which included the gene's primer sequences separated by a pUC19 plasmid sequence. Reverse transcription-polymerase chain reaction (RT-PCR) was performed on total RNA + IS using a range of 5-7 IS concentrations across a constant level of total RNA. PCR products were separated in gels (mRNA and IS-amplified sequences differed by 30-50 bases), ethidium bromide-stained, imaged (Hamamatsu Photonics Systems, Bridgewater, NJ), and quantified with NIH Image. CYP1A1 mRNA was significantly induced in the TCDD-exposed samples at all time points examined (p = 0.005 at 2 h and 0.001 after 2 h). During palatal shelf outgrowth on GD12, AhR mRNA levels increased significantly and this was not affected by treatment with TCDD or HC + TCDD. A significant increase in GR was detected at 24 h (p < 0.05) and this was unaffected by any of the exposures. Expression of ARNT increased at 12 h (p < 0.001); however, treatment with HC or HC + TCDD blocked this increase (p < 0.05). At 24 h, the TCDD-treated embryos had significantly lower ARNT mRNA compared with controls (p < 0.001). The relative overall expression level of the genes was AhR > ARNT > GR. Within individuals, expression of AhR and/or ARNT was highly correlated with GR level. In conclusion, CYP1A1 mRNA was expressed in developing craniofacial tissue and was highly induced by TCDD exposure. AhR, ARNT, and GR mRNA are upregulated in early palatogenesis, although not on the same schedule. The TCDD-induced decrease in ARNT at 24 h after dosing and the HC and HC + TCDD-induced delay in upregulation of ARNT may affect the dynamics of heterodimer formation between AhR and ARNT. The changes in ARNT mRNA level could also affect availability of this transcriptional regulator to interact with other potential partners, and these effects, separately or in combination, may be involved in disruption of normal embryonic development.

Relationships between environmental organochlorine contaminant residues, plasma corticosterone concentrations, and intermediary metabolic enzyme activities in Great Lakes herring gull embryos. (5/3283)Experiments were conducted to survey and detect differences in plasma corticosterone concentrations and intermediary metabolic enzyme activities in herring gull (Larus argentatus) embryos environmentally exposed to organochlorine contaminants in ovo. Unincubated fertile herring gull eggs were collected from an Atlantic coast control site and various Great Lakes sites in 1997 and artificially incubated in the laboratory. Liver and/or kidney tissues from approximately half of the late-stage embryos were analyzed for the activities of various intermediary metabolic enzymes known to be regulated, at least in part, by corticosteroids. Basal plasma corticosterone concentrations were determined for the remaining embryos. Yolk sacs were collected from each embryo and a subset was analyzed for organochlorine contaminants. Regression analysis of individual yolk sac organochlorine residue concentrations, or 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents (TEQs), with individual basal plasma corticosterone concentrations indicated statistically significant inverse relationships for polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans (PCDDs/PCDFs), total polychlorinated biphenyls (PCBs), non-ortho PCBs, and TEQs. Similarly, inverse relationships were observed for the activities of two intermediary metabolic enzymes (phosphoenolpyruvate carboxykinase and malic enzyme) when regressed against PCDDs/PCDFs. Overall, these data suggest that current levels of organochlorine contamination may be affecting the hypothalamo-pituitary-adrenal axis and associated intermediary metabolic pathways in environmentally exposed herring gull embryos in the Great Lakes.

Cancer mortality in agricultural regions of Minnesota. (6/3283)Because of its unique geology, Minnesota can be divided into four agricultural regions: south-central region one (corn, soybeans); west-central region two (wheat, corn, soybeans); northwest region three (wheat, sugar beets, potatoes); and northeast region four (forested and urban in character). Cancer mortality (1980-1989) in agricultural regions one, two, and three was compared to region four. Using data compiled by the National Center for Health Statistics, cancer mortality was summarized by 5-year age groups, sex, race, and county. Age-standardized mortality rate ratios were calculated for white males and females for all ages combined, and for children aged 0-14. Increased mortality rate ratios and 95% confidence intervals (CIs) were observed for the following cancer sites: region one--lip (men), standardized rate ratio (SRR) = 2.70 (CI, 1.08-6.71); nasopharynx (women), SRR = 3.35 (CI, 1.20-9.31); region two--non-Hodgkin's lymphoma (women), SRR = 1.35 (CI, 1.09-1.66); and region three--prostate (men), SRR = 1.12 (CI, 1.00-1.26); thyroid (men), SRR = 2.95 (CI, 1.35-6.44); bone (men), SRR = 2.09 (CI, 1. 00-4.34); eye (women), SRR = 5.77 (CI, 1.90-17.50). Deficits of smoking-related cancers were noted. Excess cancers reported are consistent with earlier reports of agriculturally related cancers in the midwestern United States. However, reports on thyroid and bone cancer in association with agricultural pesticides are few in number. The highest use of fungicides occurs in region three. Ethylenebisdithiocarbamates, whose metabolite is a known cause of thyroid cancer in rats, are frequently applied. This report provides a rationale for evaluation of the carcinogenic potential of this suspect agent in humans. (+info)
Quantitative analysis of constitutive and 2,3,7,8-tetrachlorodibenzo-p-dioxin-induced cytochrome P450 1B1 expression in human lymphocytes. (7/3283)Exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD or dioxin) results in a broad spectrum of biological responses, including altered metabolism, disruption of normal hormone signaling pathways, reproductive and developmental effects, and cancer. Cytochrome P450 1B1 (CYP1B1) is a dioxin-inducible gene that is active in the formation of 4-hydroxyestradiol, a potentially genotoxic catechol estrogen. Therefore, the analysis of CYP1B1 in humans may be useful in establishing relationships between dioxin exposure and adverse health effects. In this study, we examined the expression of CYP1B1 in human peripheral blood lymphocytes of unexposed individuals using a quantitative reverse transcription-PCR method. Absolute CYP1B1 RNA levels varied more than 30-fold in uncultured mononuclear cells obtained from 10 individuals. In vitro treatment of mitogen-stimulated lymphocytes with TCDD for 1-5 days of culture resulted in a peak induction of CYP1B1 after 3 days. The induction of CYP1B1 RNA levels after 3 days of culture was dose-dependent, exhibited a maximum response above 10 nM TCDD, and varied greatly among different individuals. However, the half maximal dose required for this induction was similar between individuals and comparable to that observed in the MCF-7 and HepG2 human cell lines. These observations indicate that CYP1B1 exhibits variable constitutive expression and is inducible in vitro by TCDD in human lymphocytes and that the magnitude of induction varies within the population. These data define the suitability of CYP1B1 for use as a mechanistically based biomarker in ongoing molecular epidemiological studies of human populations exposed to dioxins and related chemicals that bind the aromatic hydrocarbon receptor.

Environmental contaminants and body fat distribution. (8/3283)The effect of body mass index (BMI) and waist:hip ratio (WHR) on plasma levels of organochlorines [i.e., 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (DDE)] was investigated in a sample of black and white women drawn from a population-based study in North Carolina. Organochlorine levels were determined in plasma samples from 99 women selected on the basis of race (black versus white) and quartile of the WHR (1st versus 4th). Of a panel of 20 organochlorine compounds tested, only DDE was detectable in most study subjects. Measurements of height, weight, and waist and hip circumferences were taken during an in-person interview. Information was elicited regarding dietary, residential, and breast-feeding histories. Results of multiple regression analyses indicate that black women had significantly higher plasma levels of DDE than white women. These levels were independent of BMI and WHR. BMI but not WHR was also found to be an independent predictor of DDE plasma level. These results suggest that black/white differences should be considered in studies that explore the relationship between environmental contaminants and various disease outcomes, such as breast cancer risk. In addition, BMI may affect circulating levels of contaminants and should also be considered a potentially important modifying factor for exposure to lipophilic substances. (+info)
Persistent organic pollutant - Wikipedia
Persistent organic pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of their persistence, POPs bioaccumulate with potential adverse impacts on human health and the environment. The effect of POPs on human and environmental health was discussed, with intention to eliminate or severely restrict their production, by the international community at the Stockholm Convention on Persistent Organic Pollutants in 2001. Many POPs are currently or were in the past used as pesticides, solvents, pharmaceuticals, and industrial chemicals. Although some POPs arise naturally, for example volcanoes and various biosynthetic pathways, most are man-made via total synthesis. POPs typically are halogenated organic compounds (see lists below) and as such exhibit high lipid solubility. For this reason, they bioaccumulate in fatty tissues. Halogenated compounds also exhibit great stability reflecting the nonreactivity ...
Malaysiakini - Is US govt overreacting to widespread environmental contaminant?
LETTER , In July 2018, the US Food and Drug Administration (FDA) announced a recall of valsartan, an antihypertensive angiotensin receptor blocker (ARB), because of contamination with a cancer-causing nitrosamine, N-nitrosodimethylamine (NDMA). Initially affecting only one Chinese factory, the recall has been expanded and emulated by other regulatory bodies affecting companies and factories all over the world. In March 2019, the Singapore Health Ministry estimated that 137,000 patients have been affected by the recall of another ARB called losartan, while the Malaysian deputy minister of health has had to issue a public call for patients not to panic over the losartan recall. The list of drugs recalled by the US FDA now extends to over 1,090 entries. The chemical contaminant at the heart of the problem is also found in food especially processed meats, milk and fish. The FDA mandates that maximum intake of NDMA from the ARB drugs should not exceed 96ng/day. Yet, NDMA levels in meat products reach ...
Evaluation of the Association between Persistent Organic Pollutants (POPs) and Diabetes in Epidemiological Studies : A National...
BACKGROUND: Diabetes is a major threat to public health in the United States and worldwide. Understanding the role of environmental chemicals in the development or progression of diabetes is an emerging issue in environmental health. OBJECTIVE: We assessed the epidemiologic literature for evidence of associations between persistent organic pollutants (POPs) and type 2 diabetes. METHODS: Using a PubMed search and reference lists from relevant studies or review articles, we identified 72 epidemiological studies that investigated associations of persistent organic pollutants (POPs) with diabetes. We evaluated these studies for consistency, strengths and weaknesses of study design (including power and statistical methods), clinical diagnosis, exposure assessment, study population characteristics, and identification of data gaps and areas for future research. CONCLUSIONS: Heterogeneity of the studies precluded conducting a meta-analysis, but the overall evidence is sufficient for a positive ...

The obstetrics-gynecology community has issued a call to action to prevent toxic environmental chemical exposures and their threats to healthy human reproduction. Recent committee opinions recognize that vulnerable and underserved women may be impacted disproportionately by environmental chemical exposures and recommend that reproductive health professionals champion policies that secure environmental justice. Beauty product use is an understudied source of environmental chemical exposures. Beauty products can include reproductive and developmental toxicants such as phthalates and heavy metals; however, disclosure requirements are limited and inconsistent. Compared with white women, women of color have higher levels of beauty product-related environmental chemicals in their bodies, independent of socioeconomic status. Even small exposures to toxic chemicals during critical periods of development (such as pregnancy) can trigger adverse health consequences (such as impacts on fertility and ...

Environmental Toxins | IMBTherapies
Environmental toxins, technically called toxicants, are substances produced endogenously from the human body and which, when absorbed, inhaled, or ingested, can cause acute or chronic toxic overload, which may manifest in a variety of biological organ, tissue, and cellular-level systems. Environmental toxins are cancer-causing chemicals and endocrine disruptors, both human-made and naturally occurring. Susceptibility to toxic overload varies person-to-person, and can be affected by a variety of factors including: Genetics Environment Diet Liver and kidney health Microbiome composition and diversity Age Adiposity Gender Lifestyle Immune system capacity Screening patients with multiple chronic inflammatory symptoms, resistance to weight loss, and signs of excessive total toxic load is important to detecting unknown chemical exposure to daily products, foods, and environment Screening for Environmental Toxins can aid practitioners in uncovering true root causes of toxicity from common

For a healthier future: a virtuous cycle for reducing exposure to persistent organic pollutants | Journal of Epidemiology &...
In the modern society, people accumulate POPs through daily exposure (here, the contaminated adult stage). If individuals do not adopt measures to reduce their level of contamination, then those contaminants can be transferred from parents to fetuses. If people of reproductive age reduce the contaminants in their body before conception occurs, they can decrease pollutant levels in sperm and oocytes. If expecting mothers reduce their intake of fatty meat and fatty fish during pregnancy, they could reduce their exposure to environmental chemicals. Lower levels of exposure to the mother would then lead to diminished transplacental exposure and a less contaminated uterine environment (the fetal stage).. As noted above, reducing the breastfeeding period to a maximum of 1 year has been shown to decrease POP levels for newborns and infants.3 However, if the level of contaminants in the mothers body can be reduced before pregnancy so that breast milk is less contaminated, the breastfeeding period ...

Exposure to environmental chemicals is an important risk factor for breast cancer
Exposure to environmental chemicals, especially early in life, is an important contributing factor in the development of breast cancer, according to the most comprehensive review of human studies to date. The findings could help inform prevention strategies aimed at reducing the incidence of the disease, as rates continue to increase worldwide.. In 2007, researchers from Silent Spring Institute published in the journal Cancer a landmark state-of-the-science review on the link between environmental chemicals and breast cancer. The review identified 216 chemicals that cause mammary tumors in animals and provided a roadmap for studying these chemicals in humans. That was a real wakeup call, says Dr. Julia Brody, Silent Springs executive director and senior scientist. Now, ten years later, we see the evidence is even stronger.. Since the first review, hundreds of studies have been published on environmental chemicals and breast cancer. To capture and synthesize the human evidence, Brody and her ...
Human Exposure to Environmental Chemicals with Updated Tables (with accompanying DVD) - Nova Science Publishers
Biomonitoring is the assessment of human exposure to chemicals by measuring the chemicals of their metabolites in such human specimens as blood and urine. Most chemicals or their metabolites were measured in blood, serum and urine samples from random subsamples of about 2500 participants from the National Health and Nutrition Examination Survey conducted by the Centers for Disease Control (CDC). This book explores the ongoing assessment of the exposure of the U.S. population to environmental chemicals by the use of biomonitoring. It provides unique exposure information to scientists, physicians, and health officials to help prevent exposure to some environmental chemicals. (Imprint: Nova). ...

GLOBAL POLITICAL AWAKENING: The Global Threat of Persistent Organic Pollutants
The accumulation of POPs in fatty tissue is at the heart of the problem with these chemicals due to the fact that they can pose an even more serious threat to predators at the top of the food chain than those at the bottom. This is due to the process known as biomagnification, where POPs accumulate in the fatty tissue of organisms and become more and more concentrated as they move from one organism to the other. As they work their way through the food chain, becoming more and more contaminated as they move along, those organisms at the very top of the food chain will be ingesting the largest amounts of the chemicals. It is for this reason that even small releases of POPs can be disastrous, especially for localized ecosystems that dine on local game/fish. ...
Public health concern behind the exposure to persistent organic pollutants and the risk of metabolic diseases | BMC Public...
The incidence of obesity and diabetes has dramatically increased worldwide. From 1980 to 2008, the global prevalence of obesity has doubled in both men and women , whereas the number of people with diabetes increased from 153 million in 1980 to 347 million in 2008 . A recent report realised in the European Union (EU) highlights that overweight and obesity affect more than 50% of the adult population whereas diabetes is now affecting over 30 million people . In the United States (US), the prevalence of obesity among children and adolescents has almost tripled since 1980 , and 12% of children aged 2 through 5 years were obese in 2009-2010 . In addition to enhancing the risk of premature death, diabetes and obesity are major causes of multiple complications, including hypertension, cardiovascular diseases, asthma, blindness, limb amputation, and sleep apnea, that generate enormous economic costs for both health care and loss of productivity to society. Total annual economic cost of ...

RGC Collaborative Research fund - Layman Summaries of Projects Funded in 2008/2009 Exercise
Environmental pollutant poses potential risks to human health. Among different kinds of environmental pollutants, endocrine-disrupting pollutants have been the focus of recent studies. They share high structural and chemical similarities with those of endogenous hormones, leading to the modification of hormonal feedback circuitry and DNA methylation and chromatin patterning in the developing gametes and embryos. Their potential hazardous effects on human health are one of the global concerns that can affect the propagation of human being. The present study evaluates the risk of contaminated-fish consumption during pregnancy as well as to identify the possible pathological outcomes that may occur in the offspring. An understanding on the extent of the effect and the mechanism of action of the pollutants would help the society to devise remedial strategy.. ...
