Transcriptome Analysis of Particulate Matter 2.5-Induced Ab-normal Effects on Human Sebocytes

Project description:To investigate the effect of PM2.5 on sebocyte, we treated PM2.5 on SZ95 seboccyte and perfomed transcriptome analysis. We examined the role of PM2.5 via identification of differentially expressed genes, functional enrichment and canonical pathway analysis, upstream regulator analysis, and disease and bio-logical function analysis through mRNA sequencing. Xenobiotic and lipid metabolism, inflam-mation, oxidative stress, and cell barrier damage-related pathways were enriched; additionally, PM2.5 altered steroid hormone biosynthesis and retinol metabolism-related pathways.

Tendon methylation microarray after particulate matter inhalation

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.

Laurel (Laurus nobilis L.) transcriptomic response to urban particulate matter

Project description:This study aimed to shed light on the gene regulatory networks underlying plant leaf responses to air particulate matter. Our investigation focused on autochthonous shrubs of laurel (Laurus nobilis L.) grown in pots located in two contrasting areas: a highly polluted traffic road and rural countryside within the same town (Altopascio, Lucca, Italy). RNA-seq data were related to leaf morphological traits and air particulate matter, allowing to identify key players in modulating the capabilities of plants to phyllo-remediate high air particulate matter levels in urban environment.

Transcriptomic profile of blood cells exposed to particulate matter

Project description:Here we used next generation sequencing (NGS), to determine the transcriptional profile of blood cells exposed to particulate matter to contribute to the clarification of the importance of deregulated molecules in the molecular pathways involved in the inflammation. For this, blood cells from six adult healthy donors were treated with particulate matter.

Gene expression analysis of breast adenocarninoma cell line T47D treated with particulate matter PM2.5 sampled near the municipal solid waste incineration plant of Bologna city.

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.

Transcriptome Analysis of Particulate Matter 2.5-Induced Abnormal Effects on Human Sebocytes.

Project description:Particulate matter 2.5 (PM2.5), an atmospheric pollutant with an aerodynamic diameter of <2.5 μm, can cause serious human health problems, including skin damage. Since sebocytes are involved in the regulation of skin homeostasis, it is necessary to study the effects of PM2.5 on sebocytes. We examined the role of PM2.5 via the identification of differentially expressed genes, functional enrichment and canonical pathway analysis, upstream regulator analysis, and disease and biological function analysis through mRNA sequencing. Xenobiotic and lipid metabolism, inflammation, oxidative stress, and cell barrier damage-related pathways were enriched; additionally, PM2.5 altered steroid hormone biosynthesis and retinol metabolism-related pathways. Consequently, PM2.5 increased lipid synthesis, lipid peroxidation, inflammatory cytokine expression, and oxidative stress and altered the lipid composition and expression of factors that affect cell barriers. Furthermore, PM2.5 altered the activity of sterol regulatory element binding proteins, mitogen-activated protein kinases, transforming growth factor beta-SMAD, and forkhead box O3-mediated pathways. We also suggest that the alterations in retinol and estrogen metabolism by PM2.5 are related to the damage. These results were validated using the HairSkin® model. Thus, our results provide evidence of the harmful effects of PM2.5 on sebocytes as well as new targets for alleviating the skin damage it causes.
