Project description:Background: Mast cells play an important role in allergic responses and persistently exposure to environmental fine particulate matter (PM2.5) exacerbates allergic diseases,but the details remain elucidative. Conclusions: PM2.5 regulates ROS production through Gadd45b/MEKK4/JNK pathway, facilitating IgE-mediated mast cell activation.
Project description:Genome-wide analysis of lncRNA expression profiles in COPD rat model exposed by cigarette smoking (CS) and fine particulate matter (PM2.5). Goal was to explore the differences and similarities lncRNAs expression in rats model of COPD exposed by CS and PM2.5.
Project description:We reported the gene expression profile of T47D cells treated with the organic extract of Particulate matter 2.5 (PM2.5) sampled next to the municipal solid waste incineration plant of Bologna city. Based on a air pollution distribution model that takes the incinaration plant as point source of emission, two sites were chosen to sample particulate matter near incineration plant: "FrulloEst" representing the maximum effect of the incineration plant, "Calamosco" representing the negative control of "FrulloEst" (minimun effect of incineration plant, same effect of other air pollution fonts). Another site, "Giardini Margherita", is chosen to sample the urban background air pollution. for each site sample collection was performed in winter and in summer season.
Project description:Open tenotomy of the Achilles tendon of 6 rats was performed. The animals were divided into two groups according to exposure of PM2.5 (particulate matter less than 2.5 µm): control group (Non-PM group) or PM exposure group (PM group). After 6 weeks of PM exposure, the tendon RNA was extracted and anlyzed.
Project description:Open tenotomy of the Achilles tendon of 6 rats was performed. The animals were divided into two groups according to exposure of PM2.5 (particulate matter less than 2.5 µm): control group (Non-PM group) or PM exposure group (PM group). After 6 weeks of PM exposure, the tendon DNA was extracted and anlyzed. Genome-wide DNA methylation profiles were determinen. DNA amplicons were prepared using Differential Methylation Hybridization (DMH) method, subsequently hybridized on to the Customized Agilent Rat CpG island Microarray. The goal was to unravel the DNA methylation patterns in different subgropus of tendon tissue according to partciulate matter exposure.
Project description:Fine particulate matter (PM2.5) is an environmental pollutant associated with adverse health effects, including increased cancer risk. To investigate early transcriptional responses to PM2.5 exposure in non-malignant epithelial cells, we performed bulk RNA sequencing of wildtype mouse mammary epithelial EpH4 cells cultured under two-dimensional (2D) conditions. Cells were either left untreated or exposed to PM2.5. This dataset captures genome-wide gene expression changes induced by PM2.5 in wildtype epithelial cells and provides insight into stress response and pathophysiological pathways activated upon particulate matter exposure.
