Inflammation, the acute phase response and atherosclerosis.
Regulation of found in inflammatory zone 1 expression in bleomycin-induced lung fibrosis: J R Stat Soc Ser.
In addition to silicosis, a life-threatening lung pneumoconiosis, occupational exposure to silica is associated with the development of bronchitis, emphysema, tuberculosis, systemic sclerosis, rheumatoid arthritis, lupus, chronic renal disease and lung cancer IARC, ; Cooper et al.
Bioconductor is a project for the analysis and comprehension of genomic data and operates in R, a statistical computing environment Ihaka and Gentleman, Lipoxin A4 stable analogs inhibit leukocyte rolling and 26550 in the rat mesenteric microvasculature: Data represents the group mean of eight silica exposed and four time-matched control rats per time point.
Molecular insights into the progression of crystalline silica-induced pulmonary toxicity in rats
Oxidative stress induced lipocalin 2 gene expression: Lipoxins are products of arachidonic acid metabolism catalyzed by lipoxygenase Alox15; Kronke et al. Triggering receptor expressed on myeloid cells 1 TREM1. Disclaimer The findings and conclusions in this report leey those of the authors and do not necessarily represent the views 266505 the NIOSH.
Chemokine C — C motif ligand 3 CCl3. Bioinformatics analysis of the SDEGs supported the induction and progression of pulmonary inflammation and toxicity noticed in the silica-exposed rats.
Analogous to the human situation, progression of silica-induced pulmonary toxicity for a prolonged period after cessation of silica exposure was observed in the rat model employed in this study Table 2. The lung samples from the control and silica-exposed rats were collected to determine pulmonary toxicity and the findings have been reported recently Sellamuthu et al.
Over the most recently completed fiscal year, did the government adhere to the numerical fiscal rule? It was placed on the National Register of Historical Places in Free Radic Biol Med. This argument is further supported by the significant overexpression of LPOan H 2 O 2 -responsive gene Davies et al.
Chemokine C — C motif ligand 2 CCl2. A selected list of SDEGs belonging to the various biological functions, pathways and networks that are significantly enriched and, therefore, are considered to be of importance in the silica-induced pulmonary toxicity is presented in Table 3 and the functional significance of their differential expression with respect to the progression of silica-induced pulmonary toxicity is discussed below.
Information for Authors Order Form Newsletter. Bioinformatics analysis of the gene expression data identified molecular targets of silica toxicity and provided insights into the molecular mechanisms underlying the progression of silica-induced pulmonary toxicity in the rats. Proinflammatory activities of S A thorough characterization of the silica particles generated and employed in this inhalation exposure study was performed.
In the Easton Roller Mill was deeded 26550 the Society, and currently houses items of historical interest. Solute carrier family 26, member 4 SLC26A4. Pulmonary epithelium is a prominent source of proteinase-activated receptorinducible CCL2 in pulmonary fibrosis. Essential role of MMP in Fas-induced lung fibrosis.
After centrifugation at 10 g for 3 min at room temperature, the supernatant containing RNA was isolated and applied to the RNeasy column and processed as directed in the RNeasy Fibrous Tissue Mini Kit protocol. In short, limma fits a linear model for lej gene, generates group means of expression 265005 calculates P -values and log fold-changes which are converted to standard fold changes.
Even though the pulmonary level of lipoxins was not measured in the silica-exposed rats, our gene expression data provided indirect evidence for the involvement of lipoxins in silica-induced pulmonary inflammation. The number of biological functions, canonical pathways and molecular networks significantly affected by silica exposure, as identified by the bioinformatics analysis of the significantly differentially expressed genes detected during the post-exposure time intervals, also exhibited a steady increase similar to the silica-induced pulmonary toxicity.
It is estimated that at least 1. The number of molecular networks significantly enriched in the rat lungs in response to pulmonary exposure to silica Fig. The silica-induced pulmonary toxicity, in general, exhibited a steady progression during the post-exposure time intervals analyzed as evidenced from the various biochemical, histological and cellular toxicity parameters determined in the rats. The microarray data have been deposited in the Gene Expression Omnibus Database, http: NR1D1 expression was significantly reduced while all other genes were significantly overexpressed in the silica exposed rat lungs.
Bioinformatics analysis of the gene expression data, on the other hand, identified significant differential expression of several genes involved in tissue remodeling and fibrosis in the lungs of the silica-exposed rats as early as one week after cessation of silica exposure Table 3.
The gene expression data, in addition, may be useful to generate novel hypotheses regarding the molecular mechanisms underlying the toxicity of the agent being investigated. Antioxidants and oxidative stress. Lung Gene Expression Profile Microarray key of the global gene expression profile identified the genes whose expressions were significantly affected by silica exposure in the lungs of rats Lye Information, tables 1 — 5.

In addition, it has been fairly well established that gene expression changes relevant to toxicity precede biochemical and histological 265005 indicative of target organ toxicity Foster et al.
Chip hybridizations, washing, Cy3-streptavidin staining and scanning of the chips on the Beadstation platform Illumina Inc.
Table 4 Correlation co-efficients r 2 values for the relationship between pulmonary toxicity and inflammation measurements LDH, PMN and MCP1 and lung gene expression data in the silica exposed rats.
Significant overexpression of several members of the solute carrier SLC family of genes was noticed in the lungs of the silica-exposed rats Fig. Open in a separate window. Blood gene expression profiling detects silica exposure and toxicity. The increase in the number of SDEGs in the silica-exposed rats exhibited a trend similar 62505 the various pulmonary toxicity parameters observed during the post-exposure time intervals.
The silica-induced pulmonary toxicity in these rats, in agreement with previous reports Johnston et al. Virtually any process that involves the movement of earth or disturbance of products such as concrete and masonry may expose workers to silica.
Proyecto de Ley 2462/2012-CR
In the past, microarray-based transcriptomics studies have been successfully employed to gain insights into the molecular mechanisms underlying the toxicity of chemicals Waring et al. In summary, the data presented in this report provided insights into the molecular targets and mechanisms underlying the progression of silica-induced pulmonary toxicity in a rat model that is relevant to human silicosis.
Osteopontin, one of the key components of extracellular matrix, mediates the migration, adhesion and proliferation of fibroblasts culminating in pulmonary fibrosis Takahashi et al.
