Transcriptomic Changes in the Nasal Epithelium Associated with Diesel Engine Exhaust Exposure

ABSTRACT: Diesel engine exhaust (DEE) is one of the major contributors to air pollution around the world, and exposure to DEE is associated with lung cancer and other airway diseases. Although recent studies have investigated the effects of exposure to DEE, the mechanisms by which it leads to lung cancer pathogenesis are not well understood. We have previously investigated the transcriptomic changes that occur due to exposure to cigarette smoke and burning of bituminous (smoky) as well as anthracite (smokeless) coal in the airway epithelium, and in this study we assess the gene expression alterations in the nasal epithelium that are associated with chronic DEE exposure of diesel engine factory workers to better understand which molecular changes may lead to pathogenesis of lung cancer.

Cardiac and pulmonary responses to diesel engine particulate in Apo E(-/-) mice II

Project description:Mice deficient in Apolipoprotein E (Apoe E(-/-)) vs wild type mice were exposed to diesel engine particulate by single dose intratracheal instillation. The transcript-level response of the hearts after 24h and of the lungs after 24 h were subsequently analyzed by the 2-color microarray method. Keywords: stress response, disease state analysis Three mice of the Apo E (-/-) strain were exposed to diesel engine particulate from the National Institute of Standards and Technology via intratracheal instillation. Controls consisted of 3 littermates exposed to saline vehicle. Similarly, three wild type mice were similarly exposed to diesel particulate and three to vehicle control. 24 hours after exposure, mice were humanely sacrificed by carbon dioxide asphyxiation and the hearts and lungs were collected and frozen for analysis of total RNA. In each biological replicate, 2 color microarrays were utilized to compare pooled RNA representing all three animals of each strain, and in each condition and in each tissue; each biological replicate was performed with a dye reversal. Biological replicates of the wild type mice responses to diesel engine particulate were performed three times for heart and lung.

Buccal epithelial gene expression in smoky and smokeless coal users

Project description:Exposure to indoor air pollution generated from the combustion of solid fuels is a major risk factor for a spectrum of cardiovascular and respiratory diseases, including lung cancer. In Chinaâs rural counties of Xuanwei and Fuyuan, lung cancer rates are among the highest in the country. While the elevated disease risk in this population has been linked to the widespread usage of bituminous (smoky) coal as compared to anthracite (smokeless) coal, the underlying physiologic mechanism that smoky coal induces in comparison to other fuel types is unclear. As we have previously used airway gene-expression profiling to gain molecular insights into the physiologic effects of cigarette smoke, here we profiled the buccal epithelium of residents exposed to the burning of smoky and smokeless coal in order to understand the physiologic effects of solid fuels. Buccal mucosa scrapings were collected from healthy, non-smoking female residents of Xuanwei and Fuyuan counties who burn coal indoors. RNA was isolated and hybridized onto Affymetrix Human gene 1.0 ST GeneChips, capturing the gene-expression response of (n=26) smoky coal users and (n=9) smokeless coal users. 24-hour indoor personal exposure levels (PM2.5, Polycyclic Aromatic Hydrocarbons) were also captured during this sampling period.

In vivo endothelial transcriptomic responses to diesel engine exhaust are potentiated by hypercholesterolemia

Project description:By means of Operon V3 microarrrays, the in vivo, aortic endothelial transcriptomic responses to chronic (30 day) whole body exposure to diesel exhaust were assessed in wild type and Apo E (-/-) mice. The in vitro response of cultured Svec 4-10 cells exposed to a soluble extract extract of diesel engine particulate were similarly assessed.

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.
