Abstract

Trichloroethylene (TCE), perchloroethylene (PER), and pentachloroethane (PENT) are widely used industrial chemicals that cause an increased incidence of hepatocellular carcinoma in mice and a very low incidence of renal tubular adenocarcinoma in rats. A recent study (C. R. Elcombe, M. S. Rose, and I. S. Pratt (1985), Toxicol. Appl. Pharmacol.79, 365–376) suggested that the species difference in the hepatocarcinogenicity of TCE seen between rats and mice was due to a species difference in peroxisomal proliferation and cell proliferation. The purpose of the present investigation was to understand better the association of peroxisome proliferation in the species-specific hepatocarcinogenicity, and nephrocarcinogenicity of TCE, PER, and PENT. TCE (1000 mg/kg body wt), PER (1000 mg/kg body wt), PENT (150 mg/kg body/wt), the metabolite trichloroacetic acid (TCA; 500 mg/kg body wt),or the potent peroxisome proliferating agent Wy-14,643 (WY; 50 mg/kg body wt) was administered by gavage to male F-344 rats and B6C3F1 mice for 10 days. Cyanide-insensitive palmitoyl CoA oxidation activity (PCO) was used to measure the peroxisome proliferation response. Of the chlorinated hydrocarbons, TCE and PER elevated PCO activity in mouse liver whereas only TCE elevated rat liver and kidney PCO. All agents increased PCO activity in the kidneys of mice. None of the chlorinated hydrocarbons induced a PCO response stronger than WY. These results (1) support an association between peroxisome proliferation and hepatic tumors in mice following TCE and PER, but not PENT, administration and (2) suggest that chlorinated hydrocarbon-induced peroxisome proliferation does not correlate with species-specific renal carcinogenicity.

1,4-Dioxane as an emerging water contaminant: State of the science and evaluation of research needs
2019, Science of the Total Environment

To the best of our knowledge, no studies have examined the effects of mixtures involving 1,4-dioxane and its chlorinated solvent co-contaminants. Additive toxic effects on the liver and kidney are plausible for binary and higher-order combinations of these chlorinated compounds with 1,4-dioxane, as has been reported for the chlorinated compounds themselves in interaction studies (Goldsworthy and Popp 1987; Inoue et al. 1989). Despite the evidence of a carcinogenic effect, the mechanism by which 1,4-dioxane causes cancer is currently unclear (EPA, 2013).
1,4-Dioxane has historically been used to stabilize chlorinated solvents and more recently has been found as a contaminant of numerous consumer and food products. Once discharged into the environment, its physical and chemical characteristics facilitate migration in groundwater, resulting in widespread contamination of drinking water supplies. Over one-fifth of U.S. public drinking water supplies contain detectable levels of 1,4-dioxane. Remediation efforts using common adsorption and membrane filtration techniques have been ineffective, highlighting the need for alternative removal approaches. While the data evaluating human exposure and health effects are limited, animal studies have shown chronic exposure to cause carcinogenic responses in the liver across multiple species and routes of exposure. Based on this experimental evidence, the U.S. Environmental Protection Agency has listed 1,4-dioxane as a high priority chemical and classified it as a probable human carcinogen. Despite these health concerns, there are no federal or state maximum contaminant levels for 1,4-dioxane. Effective public health policy for this emerging contaminant requires additional information about human health effects, chemical interactions, environmental fate, analytical detection, and treatment technologies. This review highlights the current state of knowledge, key uncertainties, and data needs for future research on 1,4-dioxane.

The contributions of peroxisome proliferation and epigenetic dysregulation to TCE kidney carcinogenesis have also been evaluated. Goldsworthy et al. observed elevated cyanide-insensitive palmitoyl CoA oxidation activity, which can be used as an indicator of peroxisome proliferation [28]. It has been well recognized that epigenetic mechanisms including DNA methylation, histone modifications, and microRNAs play fundamental roles at all stages of carcinogenesis [29].
Trichloroethylene (TCE) is a widely used industrial solvent and a common environmental contaminant. It has been reported that TCE exposure is associated with a wide range of diseases, including cancer, immune system diseases, and congenital heart defect. TCE is metabolized in vivo through two main pathways, Cytochrome P450-dependent oxidation and glutathione conjugation. The adverse effects of TCE in different target tissues may be partly due to specific reactive metabolites. In this review, we will evaluate the evidence on carcinogenicity, immunotoxicity, and cardiac developmental toxicity of TCE and will discuss the potential underlying molecule mechanisms.
Trichloroethylene: Mechanistic, epidemiologic and other supporting evidence of carcinogenic hazard
2014, Pharmacology and Therapeutics
Citation Excerpt :
Limited evidence exists to suggest that TCE exposure induces peroxisome proliferation in the kidney of exposed rodents. Peroxisome proliferation in the kidney has been evaluated by only one study of TCE (Goldsworthy & Popp, 1987). Increases in renal palmitoyl–CoA oxidation activity were observed in rats and mice treated with TCE.
The chlorinated solvent trichloroethylene (TCE) is a ubiquitous environmental pollutant. The carcinogenic hazard of TCE was the subject of a 2012 evaluation by a Working Group of the International Agency for Research on Cancer (IARC). Information on exposures, relevant data from epidemiologic studies, bioassays in experimental animals, and toxicity and mechanism of action studies was used to conclude that TCE is carcinogenic to humans (Group 1). This article summarizes the key evidence forming the scientific bases for the IARC classification. Exposure to TCE from environmental sources (including hazardous waste sites and contaminated water) is common throughout the world. While workplace use of TCE has been declining, occupational exposures remain of concern, especially in developing countries. The strongest human evidence is from studies of occupational TCE exposure and kidney cancer. Positive, although less consistent, associations were reported for liver cancer and non-Hodgkin lymphoma. TCE is carcinogenic at multiple sites in multiple species and strains of experimental animals. The mechanistic evidence includes extensive data on the toxicokinetics and genotoxicity of TCE and its metabolites. Together, available evidence provided a cohesive database supporting the human cancer hazard of TCE, particularly in the kidney. For other target sites of carcinogenicity, mechanistic and other data were found to be more limited. Important sources of susceptibility to TCE toxicity and carcinogenicity were also reviewed by the Working Group. In all, consideration of the multiple evidence streams presented herein informed the IARC conclusions regarding the carcinogenicity of TCE.
The impact of CYP2E1 genetic variability on risk assessment of VOC mixtures
2011, Regulatory Toxicology and Pharmacology

Koizumi et al. (1982) reported that tetrachloroethylene inhibited the rates of urinary excretion of a 1,1,1-trichloroethane metabolite, trichloroethanol, in rats exposed by inhalation to a mixture of 350 ppm 1,1,1-trichloroethane and 100 ppm tetrachloroethylene. Goldsworthy and Popp (1987) studied the joint effect of trichloroethylene (1000 mg/kg/day) and tetrachloroethylene (1000 mg/kg/day) on peroxisome proliferation in the livers and kidneys of rats and mice. In each case except rat kidneys, the response of the peroxisome proliferation marker to the binary mixture was less than the sum of the responses to the individual chemicals.
Humans are simultaneously exposed to multiple chemicals in the environment. Many of the chemicals use the same enzymes in their metabolic pathways. Competitive inhibition may occur as one of the possible interactions between the xenobiotics in human body. For example, many volatile organic compounds (VOCs) are metabolized using P450 enzymes, specifically CYP2E1. Inheritable gene alterations may result in changes of function of the enzymes in different human subpopulations. Variations in quantity and/or quality of particular isoenzymes may cause differences in the metabolism of VOCs. These variations may cause higher sensitivity in certain populations. Using examples of three different mixtures, this review paper outlines the variances in CYP2E1 isoenzymes, effect of exposure to such mixtures on sensitive populations, and approaches to mixtures risk assessment.
Development of an updated PBPK model for trichloroethylene and metabolites in mice, and its application to discern the role of oxidative metabolism in TCE-induced hepatomegaly
2009, Toxicology and Applied Pharmacology
Trichloroethylene (TCE) is a lipophilic solvent rapidly absorbed and metabolized via oxidation and conjugation to a variety of metabolites that cause toxicity to several internal targets. Increases in liver weight (hepatomegaly) have been reported to occur quickly in rodents after TCE exposure, with liver tumor induction reported in mice after long-term exposure. An integrated dataset for gavage and inhalation TCE exposure and oral data for exposure to two of its oxidative metabolites (TCA and DCA) was used, in combination with an updated and more accurate physiologically-based pharmacokinetic (PBPK) model, to examine the question as to whether the presence of TCA in the liver is responsible for TCE-induced hepatomegaly in mice. The updated PBPK model was used to help discern the quantitative contribution of metabolites to this effect. The update of the model was based on a detailed evaluation of predictions from previously published models and additional preliminary analyses based on gas uptake inhalation data in mice. The parameters of the updated model were calibrated using Bayesian methods with an expanded pharmacokinetic database consisting of oral, inhalation, and iv studies of TCE administration as well as studies of TCE metabolites in mice. The dose–response relationships for hepatomegaly derived from the multi-study database showed that the proportionality of dose to response for TCE- and DCA-induced hepatomegaly is not observed for administered doses of TCA in the studied range. The updated PBPK model was used to make a quantitative comparison of internal dose of metabolized and administered TCA. While the internal dose of TCA predicted by modeling of TCE exposure (i.e., mg TCA/kg-d) showed a linear relationship with hepatomegaly, the slope of the relationship was much greater than that for directly administered TCA. Thus, the degree of hepatomegaly induced per unit of TCA produced through TCE oxidation is greater than that expected per unit of TCA administered directly, which is inconsistent with the hypothesis that TCA alone accounts for TCE-induced hepatomegaly. In addition, TCE-induced hepatomegaly showed a much more consistent relationship with PBPK model predictions of total oxidative metabolism than with predictions of TCE area-under-the-curve in blood, consistent with toxicity being induced by oxidative metabolites rather than the parent compound. Therefore, these results strongly suggest that oxidative metabolites in addition to TCA are necessary contributors to TCE-induced liver weight changes in mice.
In vitro screening of 200 pesticides for agonistic activity via mouse peroxisome proliferator-activated receptor (PPAR)α and PPARγ and quantitative analysis of in vivo induction pathway
2006, Toxicology and Applied Pharmacology
Peroxisome proliferator-activated receptors (PPARs) are ligand-dependent transcription factors and key regulators of lipid metabolism and cell differentiation. However, there have been few studies reporting on a variety of environmental chemicals, which may interact with these receptors. In the present study, we characterized mouse PPARα and PPARγ agonistic activities of 200 pesticides (29 organochlorines, 11 diphenyl ethers, 56 organophosphorus pesticides, 12 pyrethroids, 22 carbamates, 11 acid amides, 7 triazines, 8 ureas and 44 others) by in vitro reporter gene assays using CV-1 monkey kidney cells. Three of the 200 pesticides, diclofop-methyl, pyrethrins and imazalil, which have different chemical structures, showed PPARα-mediated transcriptional activities in a dose-dependent manner. On the other hand, none of the 200 pesticides showed PPARγ agonistic activity at concentrations ≤ 10^− 5 M. To investigate the in vivo effects of diclofop-methyl, pyrethrins and imazalil, we examined the gene expression of PPARα-inducible cytochrome P450 4As (CYP4As) in the liver of female mice intraperitoneally injected with these compounds (≤ 300 mg/kg). RT-PCR revealed significantly high induction levels of CYP4A10 and CYP4A14 mRNAs in diclofop-methyl- and pyrethrins-treated mice, whereas imazalil induced almost no gene expressions of CYP4As. In particular, diclofop-methyl induced as high levels of CYP4A mRNAs as WY-14643, a potent PPARα agonist. Thus, most of the 200 pesticides tested do not activate PPARα or PPARγ in in vitro assays, but only diclofop-methyl and pyrethrins induce PPARα agonistic activity in vivo as well as in vitro.
