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

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.

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.

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.

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).

Project description:Exposure to particulate matter (PM) in ambient air is known to increase the risk of cardiovascular disorders and mortality. The cytotoxicity of PM is mainly due to the abnormal increase of reactive oxygen species (ROS), which damage cellular components such as DNA, RNA, and proteins. The correlation between PM exposure and human disorders, including mortality, is based on long-term exposure. In this study we have investigated acute responses of mucus-secreting goblet cells upon exposure to PM derived from a heavy diesel engine. To this end, we employed the mucociliary epithelium of amphibian embryos and human Calu-3 cells to examine PM mucotoxicity. Our data suggest that acute exposure to PM significantly impairs mucus secretion and results in the accumulation of mucus vesicles in the cytoplasm of goblet cells. RNA-seq analysis revealed that acute responses to PM exposure significantly altered gene expression patterns; however, known regulators of mucus production and the secretory pathway were not significantly altered. Interestingly, pretreatment with α-tocopherol nearly recovered the hyposecretion of mucus from both amphibian and human goblet cells. We believe this study demonstrates the mucotoxicity of PM and the protective function of α-tocopherol on mucotoxicity caused by acute PM exposure from heavy diesel engines.
