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.

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.  (+info)

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.  (+info)

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.  (+info)

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.  (+info)

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.  (+info)

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)

Latest findings suggest that the chemicals, which are no longer produced in the United States but persist in the environment, may have lasting health effects even at low levels. POPs, PBTs and vPvBs There are three groups of persistent substances mentioned in regulations: - POP, Persistent Organic Pollutants - PBT, Persistent, Bio-accumulative and Toxic substances - vPvB, very Persistent and very Bio-accumulative substances Persistent means that these substances will not (bio)degrade. The new regulation repeals the POP Regulation (EC) No 850/2004 and comes into force on 15 July 2019. L 169, 25.6.2019, p. 45). Persistent organic pollutants (POPs) are chemical substances that persist in the environment, bioaccumulate through the food web, and pose a risk of causing adverse effects to human health and the environment. sponsor this page to leave your contact info on this page..

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 ...
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 ...
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, 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

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, 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 ...
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). ...

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. ...
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 [1], whereas the number of people with diabetes increased from 153 million in 1980 to 347 million in 2008 [2]. 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 [3]. In the United States (US), the prevalence of obesity among children and adolescents has almost tripled since 1980 [4], and 12% of children aged 2 through 5 years were obese in 2009-2010 [5]. 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 ...

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.. ...
