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:We examined the impact of chronic lung inflammation on the pulmonary transcriptional response to inhaled urban particles. Transcript levels were measured using high density microarrays in total RNA isolated from whole lungs of wildtype and TNF-α overexpressing mice exposed by inhalation to particulate matter and euthanized immediately or 24 h post-exposure. Keywords: Toxicology, disease state analysis, stress response
Project description:We examined the impact of chronic lung inflammation on the pulmonary transcriptional response to inhaled urban particles. Transcript levels were measured using high density microarrays in total RNA isolated from whole lungs of wildtype and TNF-α overexpressing mice exposed by inhalation to particulate matter and euthanized immediately or 24 h post-exposure. Experiment Overall Design: Transgenic SP-C/TNF-α mice and their wildtype littermates were exposed by inhalation to particulate matter (0, 42 mg/m3 EHC-93) for 4 h and euthanized immediately or 24 h post-exposure (n=5 per treatment per time point, 40 animals total). Agilent 22K oligonucleotide microarrays were used to examine transcript levels in whole lung RNA. Stratagene Universal Mouse RNA was used as a reference.
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.
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.
