In vitro transformation of human bronchial epithelial cells by diesel exhaust particles

ABSTRACT: The potential of diesel exhaust particles (DEP) to transform human bronchial epithelial cells (HBEC3) was investigated and a stably transformed cell line (T2-HBEC3) was established. Short-term DEP exposure experiments adds information of immunomodulatory effect markers and differences in susceptibility between normal and sensitized bronhial epithelial cells of the human lung.

DNA methylation changes in A549 cells after four weeks of exposure to 30 μg/ml diesel exhaust particles.

Project description:Diesel exhaust particles (DEP), which contain hazardous compounds, are emitted during the combustion of diesel. As approximately one-third of the vehicles worldwide use diesel, there are growing concerns on the risks posed by DEP to human health. Long-term exposure to DEP is associated with airway hyperresponsiveness, pulmonary fibrosis, and inflammation; however, the molecular mechanisms behind the effects of DEP on the respiratory tract are poorly understood. Such mechanisms can be addressed by examining transcriptional and DNA methylation changes. In this study, we investigated the effect of 4 weeks exposure to 30 μg/ml DEP on DNA methylation levels in A549 cells.

Proteomic analysis reveals activation of platelet- and fibrosis-related pathways in hearts of ApoE-/- mice exposed to diesel exhaust particles

Project description:Air pollution is an environmental risk factor linked to multiple human diseases including cardiovascular diseases (CVDs). While particulate matter (PM) emitted by diesel exhaust damages multiple organ systems, heart disease is one of the most severe pathologies affected by PM. However, the in vivo effects of diesel exhaust particles (DEP) on the heart and the molecular mechanisms of DEP-induced heart dysfunction have not been investigated. In the current study, we attempted to identify the proteomic signatures of heart fibrosis caused by diesel exhaust particles (DEP) in CVDs-prone apolipoprotein E knockout (ApoE-/-) mice model using tandem mass tag (TMT)-based quantitative proteomic analysis. DEP exposure induced mild heart fibrosis in ApoE-/- mice compared with severe heart fibrosis in ApoE-/- mice that were treated with CVDs-inducing peptide, angiotensin II. TMT-based quantitative proteomic analysis of heart tissues between PBS- and DEP-treated ApoE-/- mice revealed significant upregulation of proteins associated with platelet activation and TGFβ-dependent pathways. Our data suggest that DEP exposure could induce heart fibrosis, potentially via platelet-related pathways and TGFβ induction, causing cardiac fibrosis and dysfunction.

Differentially expressed genes related to inflammatory disease on nasal cavity induced by diesel exhaust particles (DEPs)

Project description:Recently air pollution has become serious environmental issues effect. Contaminated air by pollutants, such as emission of diesel fuel, enter the human body through airway tract and can cause inflammatory diseases in respiratory system. The relation between air pollutant and development of respiratory diseases have well-studied, but the processes of disease outbreak were not fully studied yet. We investigated global gene expression induced by diesel exhaust particle (DEP), one of air pollutants in primary human nasal epithelial cell (PHNEC) with the purpose of identifying potential biomarkers. Furthermore, we analyzed signaling pathway among differentially expressed genes (DEGs) for elucidating signaling networks of process developing airway diseases. Consequentially, we suggested several key biomarkers that include not only the expression changes but also the meaning of relation between genes. This findings might be used for early diagnosis and prevention of upper respiratory disease, especially rhinitis.

Lung cell responses to ship diesel exhaust particles

Project description:Human BEAS-2B bronchial epithelial cells were exposed directly at the air-liquid interphase towards exhaust gas and particles of a ship engine. The goal was to compare the responses towards different fuel combustions. The engine run either on diesel fuel (DF) or on Heavy Fuel Oil (HFO). The lung cells were exposed 3 times to each combustion aerosol (DF or HFO). The duration of the exposure was 4h. The cells were seeded into transwell-inserts 24h before exposure. Within each exposure 3 transwell-inserts were exposed to the complete aerosol and 3 transwell-inserts were exposed to the filtered aerosol. Effects of the complete aerosol were referenced against the filtered aerosol to determine the effects of the aerosol particles.

Differential Transcriptional Changes in Mice Exposed to Chemically Distinct Diesel Samples

Project description:Epidemiological studies have linked exposure to ambient particulate matter (PM) with increased asthmatic symptoms. Diesel exhaust particles (DEP) are a predominant source of vehicle derived ambient PM, and experimental studies have demonstrated that they may have adjuvant potential when given with an antigen. We previously compared 3 DEP samples: N-DEP, A-DEP, and C-DEP in a murine ovalbumin (OVA) mucosal sensitization model and reported the adjuvant activity to be: C-DEP ? A-DEP > N-DEP. The present study analyzed gene expression changes from the lungs of these mice. Transcription profiling demonstrated that all the DEP samples altered cytokine and toll-like receptor pathways regardless of type, with or without antigen sensitization. Further analysis of DEP exposure with OVA showed that all DEP treatments altered networks involved in immune and inflammatory responses. The A- and C-DEP/OVA treatments induced differential expression of apoptosis pathways in association with stronger adjuvant responses, while expression of cell cycle control and DNA damage pathways were also altered in the C-DEP/OVA treatment. This comprehensive approach using gene expression analysis to examine changes at a pathway level provides detailed information on events occurring in the lung after DEP exposure, and confirms that the most bioactive sample induced many more individual genes and changes in immuno-regulatory and homeostatic pathways. Female BALB/C mice (8-10 weeks old) were randomly divided into 8 treatment groups containing 3 mice each and exposed to saline, 20 ug ovalbumin, 150 ug diesel exhaust particles (either C-DEP, A-DEP, or N-DEP), or diesel exhaust particles + ovalbumin by intranasal instillation on Days 0 and 13 and necropsied 18 hrs latter.
