Sub-chronic pulmonary transcriptional response to a mixture of 8 polycyclic aromatic hydrocarbons in adult male MutaTMMouse.

ABSTRACT: Polycyclic aromatic hydrocarbons (PAHs) are a class of hundreds of structurally similar chemicals ubiquitously present in our environment. They are created during the incomplete combustion of organic materials, such as oil, wood, tobacco, and charbroiled meat. As such, human exposure to mixtures of PAHs can occur through consumption of PAH-containing foods and water, inhalation of polluted air, or dermal contact. Several PAHs have been classified as carcinogenic to humans or probably carcinogenic to humans by the International Agency for Research on Cancer. The mice in this study were exposed to a mixture of 8 PAHs, benzo(a)pyrene, benz(a)anthracene, benzo(b)fluoranthene, benzo(ghi)perylene, benzo(k)fluoranthene, chrysene, dibenz(ah)anthracene, and indeno(123,cd)pyrene. In the present study, we sought to determine the dose-dependent changes in gene expression upon oral exposure to this PAH mixture in the lung tissue. Adult male MutaTMMouse were exposed to three doses of the mixture of 8 PAHs or vehicle control (olive oil) for 28 days and sacrificed three days after the final exposure.

Induction of active hepatic cytochrome P450 enzymes in mice exposed to benzo[a]pyrene or environmental mixtures of polycyclic aromatic hydrocarbons

Project description:Cytochrome P450 enzymes play an important role in bioactivating or detoxifying polycyclic aromatic hydrocarbons (PAHs). We exposed mice to doses of benzo[a]pyrene (BaP) or a mixture of PAHs to characterize dose- and time-response relationships of specific cytochrome P450s. Mice exposed to the highest PAH exposures exhibited 1.7-5-fold higher intrinsic clearance rates for BaP, compared to controls, and higher Vmax values, indicating higher amounts of enzymes capable of metabolizing BaP. This study demonstrates that PAHs induce enzymes in dose- and time-dependent patterns in animal models at exposure levels researchers use to characterize hazards and at relevant human exposure levels to PAH mixtures found at Superfund sites. Accounting for these potential changes in enzyme profiles, relative rates of PAH bioactivation and detoxification, and resulting risk will help reduce uncertainty and improve risk assessments for PAHs at contaminated sites.

HepG2 treated with Polycyclic Aromatic Hydrocarbons (PAHs)

Project description:Assessing the potential carcinogenicity of human toxins represents an ongoing challenge. Chronic rodent bioassays predict human cancer risk with limited reliability, and are expensive and time-consuming. To identify alternative prediction methods, we evaluated a transcriptomics-based human in vitro model to classify carcinogens by their modes of action. The aim of this study was to determine the transcriptomic response and identify specific molecular signatures of polycyclic aromatic hydrocarbons (PAHs), which can be used as predictors of carcinogenicity of environmental toxins in human in vitro systems. We found that characteristic molecular signatures facilitate identification and prediction of carcinogens. To evaluate the change in gene expression levels, human hepatocellular carcinoma (HepG2) cells were exposed to nine different PAHs (benzo[a]pyrene, dibenzo[a,h]anthracene, 3-methylcholanthrene, naphthalene, chrysene, phenanthrene, benzo[a]anthracene, benzo[k]fluoranthene, and indeno[1,2,3-c,d]pyrene) for 48 h. Gene expression analysis was conducted using a 44K whole human genome microarray (Agilent Technologies, USA).
