An extensive literature survey on correlation of biomarkers resulted in the following preliminary conclusions: • No significant correlation between individual pairs of DNA adducts was found in a number of the 32P-postlabelling and immunoassay studies, indicating limited overlapping of the substrate specificity of the different DNA adduct methods. • Attempts to show correlations between a group of related DNA adduct structures and a chemically specific single DNA adduct structure by using the same type of methodology gave controversial results. These suggest the co-existence of both closely linked and independent metabolic activation pathways for complex mixtures of xenobiotics, and may also reflect differences in the kinetics of DNA adduct formation and elimination. • A larger number of studies revealed a positive correlation between DNA adduct levels in target and surrogate tissues than did not find a correlation. Correlation may depend on exposure dose and the metabolic capacity of the ...

40 Although 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) was one of the most potent environmental carcinogen, mechanisms of action of TCDD at the molecular level are poorly understood. To enhance our understanding of carcinogenicity by TCDD, we investigated which genes are involved in TCDD-induced chemical carcinogenesis using two human liver cells, hepatoma HepG2 and non-tumorigenic fetal hepatic WRL68 cells. We found that TCDD (1nM) decreased HepG2 cell growth over 50%, but had no effect on WRL68 cell growth. We used DNA microarray to identify genes whose expression are changed at 24 hours after treatment with TCDD (0.1nM) in both of cell lines. We found that TCDD commonly down-regulated P21, sod1 genes and up-regulated hsp27, hsp90 genes, two fold or more. Moreover, TCDD (0.1nM) increased the levels of 8-hydroxy-2-deoxyguanosine (8-OHdG), typical biomarker of oxidative stress, with time dependency in HepG2 cell, but just transiently increased the levels of 8-OHdG after 2 hours in WRL68 cell. ...

The carcinogenic effects of individual polycyclic aromatic hydrocarbons (PAH) are well established. However, their potency within an environmental complex mixture is uncertain. We evaluated the influence of diesel exhaust particulate matter on PAH-induced cytochrome P450 (CYP) activity, PAH-DNA adduct formation, expression of certain candidate genes and the frequency of tumor initiation in the two-stage Sencar mouse model. To this end, we monitored the effects of treatment of mice with diesel exhaust, benzo[a]pyrene (BP), dibenzo[a,l]pyrene (DBP), or a combination of diesel exhaust with either carcinogenic PAH. The applied diesel particulate matter (SRM(1975)) altered the tumor initiating potency of DBP: a statistically significant decrease in overall tumor and carcinoma burden was observed following 25 weeks of promotion with 12-O-tetradecanoylphorbol-13-acetate (TPA), compared with DBP exposure alone. From those mice that were treated at the beginning of the observation period with 2 nmol DBP ...
When present in soil, the oxidized forms of certain metallic contaminants (e.g., hexavalent chromium) are quite mobile and can be easily carried by waters percolating through the unsaturated zone. To avoid the excessive costs and risks associated with excavation, transportation, and disposal of the chromium contamination at locations such as Pantex, Hanford, and the Sandia National Laboratory, the Department of Energy (DOE) is testing the In-Situ Gaseous Reduction System (IGRS). In IGRS, the oxidized metals are reduced and immobilized. For chromium-contaminated sites, the primary chemical reaction involves the reduction of hexavalent chromium [Cr (VI)] to trivalent chromium [Cr (III)], with subsequent precipitation as a nontoxic, insoluble solid ...
Many human carcinogens are environmental carcinogens, for example, polychlorinated biphenyls (PCBs) from transformers. Other known carcinogens are tobacco smoke, aflatoxins (produced by moldy peanuts), sunlight (increase in malignant melanoma and squamous cell carcinoma), radiation, chemicals, dioxin, and benzene. Most authorities believe that the herpes viruses and papillomaviruses have a potential for producing cancerous changes. Patients with a history of certain diseases, such as hepatitis, have a higher incidence of liver cancer than patients without such history.. Normal cells have a mechanism to turn off cell growth with certain signals. In cancer, however, a change in the cells occurs so that they continue to grow. With a lack of control (switch does not turn off), the abnormal neoplastic cells continue to grow. The cell-surface antigens appear similar to the normal fetal types, so the body does not mount an immune response. The tumor stem cells have chromosomal abnormalities, ...
A recent article (1) attempted to estimate the false-positive rate for cancer epidemiology studies based on agents in International Agency for Research on Cancer (IARC) category 3 (agent not classifiable as to its carcinogenicity to humans) in the IARC Monographs Program. The estimation method used was based on the assumption that the IARC classification of agents about their carcinogenic potential (or any similar human endeavor at reaching consensus) provides a scientifically sound basis for assessing the false-positive rate in cancer epidemiology studies. Any such consensus effort uses classification criteria, and we critique the proposed false-positive rate estimation method because of potential biases induced by its reliance on the IARC criteria for assessing carcinogenic potential. The IARC criteria give epidemiologic studies epistemic priority in working group deliberations, and accordingly, the IARC category to which an agent is assigned will depend strongly on the percentage of positive ...
Particulate hexavalent chromium (Cr(VI)) is a potent respiratory carcinogen with widespread human exposure. The particulate form, for example lead chromate, has been determined to be the most toxic and carcinogenic form. These particles impact at bifurcation sites of the lung and persist in the respiratory tract. Chromosome instability (CIN) is a hallmark of lung cancer with cells exhibiting both translocations and severe aneuploidy. However, the ability of Cr(VI) to induce translocations is unknown. We exposed human lung cells to lead chromate for three sequential 24 h periods, each separated by about a month. After each treatment, cells were seeded at colony forming density, cloned, expanded and retreated. Each generation of clones were tested for their chromium sensitivity, chromosome complement and DNA repair capacity. We found that after the first treatment, lead chromate-treated cells exhibited a normal chromosome complement though a few clones showed an increase in relative survival. ...

Substances, mixtures and exposure circumstances in this list have been classified by the IARC as Group 2A: The agent (mixture) is probably carcinogenic to humans. The exposure circumstance entails exposures that are probably carcinogenic to humans. This category is used when there is limited evidence of carcinogenicity in humans and sufficient evidence of carcinogenicity in experimental animals. In some cases, an agent (mixture) may be classified in this category when there is inadequate evidence of carcinogenicity in humans and sufficient evidence of carcinogenicity in experimental animals and strong evidence that the carcinogenesis is mediated by a mechanism that also operates in humans. Exceptionally, an agent, mixture or exposure circumstance may be classified in this category solely on the basis of limited evidence of carcinogenicity in humans. Further details can be found in the IARC Monographs. ...

N2 - Magnetic natural zeolite-polypyrrole (MZ-PPy) composite was prepared for enhanced removal of hexavalent chromium [Cr(VI)] from aqueous solution. The structure and morphology of the prepared adsorbent was analyzed with the Fourier transform infrared (FTIR), field-emission microscope (FE-SEM), energy dispersive X-ray (EDX), high resolution transmission electron microscope (HR-TEM) and X-ray diffraction (XRD). The effects of magnetic zeolite loading within the composite, initial pH, sorbent dosage, temperature and Cr(VI) concentration on Cr(VI) removal efficiency were investigated. Up to 99.99% removal efficiency was obtained when the pH was 2 and the initial Cr(VI) concentration was 300 mg/L. The sorption kinetic data fitted well to the pseudo-second order model and isotherm data fitted well to the ...
TP53 is one of the most commonly mutated genes in human tumours. Variations in the types and frequencies of mutations at different tumour sites suggest that they may provide clues to the identity of the causative mutagenic agent. A useful model for studying human TP53 mutagenesis is the partial human TP53 knock-in (Hupki) mouse containing exons 4-9 of human TP53 in place of the corresponding mouse exons. For an in vitro assay, embryo fibroblasts from the Hupki mouse can be examined for the generation and selection of TP53 mutations because mouse cells can be immortalized by mutation of Tp53 alone. Thus far, four environmental carcinogens have been examined using the Hupki embryo fibroblast immortalization assay: (a) UV light, which is linked to human skin cancer; (b) benzo[a] pyrene, which is associated with tobacco smoke-induced lung cancer; (c) 3-nitrobenzanthrone, a suspected human lung carcinogen linked to diesel exposure; and (d) aristolochic acid, which is linked to Balkan endemic ...
Groups of 10 male and 10 female rats were fed diets containing 0, 99, 163, 234, or 484 ppm fumonisin B1 for 28 days. There were no exposure-related deaths in rats. The mean body weights of the 484 ppm groups were significantly less (-16%) than those of the controls. Dietary concentrations of 99, 163, 234, and 484 ppm fumonisin B1 resulted in average daily doses of 12, 20, 28, and 56 mg fumonisin B1/kg body weight for males and females. Additional groups of male and female rats were exposed to the same concentrations of fumonisin B1 for 28 days for clinical pathology studies. The concentrations of creatinine, cholesterol, triglycerides, and total bile acids, as well as activities of the enzymes alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, and -glutamyltransferase, were generally significantly greater in the 484 ppm groups than in the control groups at all time points, indicating hyperlipidemia and a hepatic effect. Fumonisin B1 is an inhibitor of ceramide synthase, ...

Three compounds, hypothesized as fumonisin A1 (FA1), fumonisin A2 (FA2), and fumonisin A3 (FA3), were detected in a corn sample contaminated with mycotoxins by high-resolution liquid chromatography-Orbitrap mass spectrometry (LC-Orbitrap MS). One of them has been identified as FA1 synthesized by the acetylation of fumonisin B1 (FB1), and established a method for its quantification. Herein, we identified the two remaining compounds as FA2 and FA3, which were acetylated fumonisin B2 (FB2) and fumonisin B3 (FB3), respectively. Moreover, we examined a method for the simultaneous analysis of FA1, FA2, FA3, FB1, FB2, and FB3. The corn samples were prepared by extraction using a QuEChERS kit and purification using a multifunctional cartridge. The linearity, recovery, repeatability, limit of detection, and limit of quantification of the method were >0.99, 82.9%-104.6%, 3.7%-9.5%, 0.02-0.60 μg/kg, and 0.05-1.98 μg/kg, respectively. The simultaneous analysis of the six fumonisins revealed that FA1, FA2,

Substances, mixtures and exposure circumstances in this list have been classified by the International Agency for Research on Cancer (IARC) as Group 3: The agent (mixture or exposure circumstance) is not classifiable as to its carcinogenicity to humans. This category is used most commonly for agents, mixtures and exposure circumstances for which the evidence of carcinogenicity is inadequate in humans and inadequate or limited in experimental animals. Exceptionally, agents (mixtures) for which the evidence of carcinogenicity is inadequate in humans but sufficient in experimental animals may be placed in this category when there is strong evidence that the mechanism of carcinogenicity in experimental animals does not operate in humans. Agents, mixtures and exposure circumstances that do not fall into any other group are also placed in this category.

Hexavalent chromium [Cr (VI)] exists at the Superfund sites where it poses major health concerns to humans. Bacteria-mediated in situ reductive transformation of water soluble and toxic Cr(VI) to insoluble and less toxic Cr(III) in the form of Cr2O3 nanoparticle precipitates represents a promising method for bioremediation of Cr(VI) contamination. This research project focused on characterizing the molecular mechanism by which bacteria Shewanella oneidensis MR-1 reduces Cr (VI). Through the R01 project, the research team identified and demonstrated that that cell surface-exposed ctype cytochromes MtrC and OmcA of Shewanella play a critical role in the formation of Cr (III) particles on the bacterial cell surfaces by reducing Cr (VI) directly as Cr (VI) terminal reductases and indirectly as Fe (III) oxide terminal reductases to produce Fe (II) that in turn reduces Cr (VI).. Furthermore, the research team has applied the nanoscale AFM correlated SERS imaging microscopy (AFMCSIM), TEM, SEM, and ...
BaPs metabolites are mutagenic and highly carcinogenic, and it is listed as a Group 1 carcinogen by the IARC. Chemical agents and related occupations, Volume 10, A review of Human Carcinogens, IARC Monographs, Lyon France 2009 [15] In June 2016, BaP was added as benzo[def]chrysene to the REACH Candidate List of Substances of very high concern for Authorisation.[16] Numerous studies since the 1970s have documented links between BaP and cancers.[17] It has been more difficult to link cancers to specific BaP sources, especially in humans, and difficult to quantify risks posed by various methods of exposure (inhalation or ingestion).[18] A link between vitamin A deficiency and emphysema in smokers was described in 2005 to be due to BaP, which induces vitamin A deficiency in rats.[19] A 1996 study provided molecular evidence linking components in tobacco smoke to lung cancer. BaP was shown to cause genetic damage in lung cells that was identical to the damage observed in the DNA of most malignant ...

Exposure to environmental carcinogens and genetic variation in response to this exposure have been linked to both SCCHN and SPM (7, 16, 17). As phase II detoxifying enzymes, the GSTs have been targeted as possible genetic biomarkers to predict malignancy risk. GSTs have been most consistently reported to confer increased risk for lung and bladder malignancies (6). Whereas individual studies have reported varying associations between GSTs and SCCHN, meta-analyses and pooled analyses of GSTM1, GSTT1, and GSTP1 genotypes have revealed modest associations of the GSTM1 null, GSTT1 null, and GSTP1 Ile105Val polymorphism with risk of SCCHN. Furthermore, combination of these three polymorphisms into a multigenic model conferred a 2.1-fold increased risk of SCCHN (7).. The same genetic susceptibility that confers risk for index cancer may also increase risk for development of SPM, which remains a cause of significant morbidity and mortality among SCCHN patients. Small studies have previously examined the ...
