Project description:The goal of this study was to evaluate the biological effect of microplastic fibres on nasal epithelium from healthy subjects, as well as asthma and COPD pateients. We demonstrated the distinct biological response of asthmatic and COPD epithelial cells to microplastic fibers stimulation compared to healthy epithelial cells. ANKRD36, BCL2L15, C15orf48, CAPN14, FCGBP, FST, IL-19, MAFF, PGBD5, PKP1 and PTPRH are important markers of epithelial response after microplastic stimulation in obstructive lung disaeses. These mediators are linked to Th2 inflammation, alleviation of stress response, and, most notably, carcinogenesis.

These mediators are linked to Th2 inflammation, alleviation of stress response, and, most notably, carcinogenesis. Microplastic stimulation differently modified the response of airway epithelial cells in obstructive lung diseases than in controls. Asthmatic and COPD epithelial cells are more prone to damage after microplastic fibre exposure.

Project description:The effects of the aromatic hydrocarbons benzene and toluene on Nitrosomonas europaea, a nitrifying bacterium that plays an important role in the removal of nitrogen from wastewater treatment plants, were studied in batch reactors. Exposure to 20 M toluene and 40 M benzene resulted in a 50% reduction in nitrifying activity after 1 h. However, Affymetrix microarray experiments detected no significant changes in gene expression in toluene exposed cells. Cells exposed to benzene were found to up-regulate a gene cluster (NE 1545 - NE 1551). This gene cluster appears to be involved with fatty-acid metabolism, lipid and membrane protein biosynthesis. TEM experiments reveal that cells exposed to benzene decrease the thickness of their membrane and the membrane becomes more structured. Keywords: stress response, benzene, toluene
Project description:In this paper, we present the first comparative transcriptome profiles with ARR treated and control of R. palustris. Moreover, putative two ARR biotransformation mechanisms in R. palustris were first given. All of these provided a valuable genomic resource for further studying molecular mechanism of biotransformation and genetic modification of R. palustris.
