The silica-induced pulmonary inflammation in the rats, similar to the trend exhibited by the various parameters of silica-induced pulmonary toxicity, exhibited a steady progression during the post-exposure time intervals analyzed Table 2.
Pulmonary fibrosis is a major component of silicosis Ng and Chan,the most serious health outcome of occupational exposure to silica. Excessive mucus production, as implicated by significant overexpression of the pendrin coding gene, SLC26A4was identified as a potential novel mechanism for silica-induced pulmonary toxicity.
Is the government required to set pre-defined criteria by which companies become qualified to participate in a licensing process? FIZZ1, a novel cysteine-rich secreted protein associated with pulmonary inflammation, defines a new gene family.
As presented in Table 4the various pulmonary toxicity parameters correlated well with the gene expression findings in the silica-exposed rats. Lipoxin A4 modulates transmigration of human neutrophils across intestinal epithelial monolayers. Chip hybridizations, washing, Cy3-streptavidin staining and scanning of the chips on the Beadstation platform Illumina Inc. Complement activation contributes to leukocyte recruitment and neuropathic pain following peripheral nerve injury in rats.
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.

The top ranking biological functions significantly affected by silica exposure were inflammatory response, cell-to-cell signaling and interaction, cellular movement, inflammatory diseases, respiratory diseases and cancer Fig. The number of genes differentially expressed totaloverexpressed up and under expressed down in the silica exposed rat lungs compared with the corresponding time-matched controls are presented for the post-exposure time intervals presented on the X-axis. Table 3 Fold change in expression of a selected list of significantly differentially expressed genes in the lungs of silica exposed rats.
In short, limma fits a linear model for each gene, generates group means of expression and calculates P -values and log fold-changes which are converted to standard fold changes.
Collectively, the findings of this study and those reported previously Nakao et al.
International Agency for Research on Cancer; From onwards, and prior to each Respiratory tract mucin genes and mucin glycoproteins in health and disease. J Radiat Res Tokyo ; Microarray analysis of the global gene expression profile identified the genes whose expressions were significantly affected by silica exposure in the lungs of rats Supporting Information, tables 1 — 5. In addition several monographs have been published and are for sale to the public.
The findings of the present transcriptomics study also provided novel insights into the mechanisms potentially underlying the progression of silica-induced pulmonary toxicity related to upper airway diseases. Advances in high-throughput gene expression profiling, such as microarray analysis, enable a comprehensive understanding of the effects of toxic agents at the molecular level in biological systems.
To do this, the Society conducts four dinner meetings each year with programs involving historical subjects. Lung Gene Expression Profile Microarray analysis of the global gene expression profile identified the genes whose expressions were significantly affected by silica exposure in the lungs of rats Supporting Information, tables 1 — 5.
Identification of putative gene based markers of renal toxicity. Commercial sources of all other reagents used in this study are provided in the corresponding sections below. National Center for Biotechnology InformationU. A definite role for MMP12 lwy the induction of pulmonary fibrosis has been demonstrated previously in mice carrying a targeted deletion of the MMP12 gene Matute-Bello et al.

Significant increase in the number of AMs and PMNs and concentrations of the pro-inflammatory chemokines, MCP1 and MIP2, noticed in the lung samples used in this study Table 2suggested the induction of significant pulmonary inflammation in our rat model. Matrix metalloproteinases MMPs are a family of proteins participating in many normal biological processes as well as in pathological processes, including fibrotic lung diseases Nagase and Woessner, Supp File 5 Click here to view.
Meetings are held at 6: Has the government publicly disclosed a national budget that has been enacted for the current fiscal year?
In addition, results of the bioinformatics analysis of the SDEGs, in agreement with the findings of several previous studies, reaffirmed the ability of silica exposure to result in the induction of inflammation Barbarin et al. The number of SDEGs belonging to each of these top ranking biological functions, as in the case of silica-induced pulmonary toxicity Table 2also exhibited a steady increase during the post-exposure time intervals analyzed Fig.

Association of serum arginase I with oxidative stress in a healthy population. Osteopontin, one of the key components of extracellular matrix, mediates the migration, adhesion and proliferation of fibroblasts culminating in pulmonary fibrosis Takahashi et al. Purpose of the Society The purpose of the Society is to further the awareness of history with emphasis on the Monongalia County area, which initially was composed of several present-day West Virginia counties as well as a portion of southwestern Pennsylvania.
Data 25605 the group mean of eight silica exposed and four time-matched control rats per time point. 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.
Forty rats exposed simultaneously to filtered air served as the controls. NR1D1 expression was significantly reduced while all other genes were significantly overexpressed in the silica exposed rat lungs.
A chemoattractant cytokine associated with granulomas in tuberculosis and silicosis. It has been reported previously that forced overexpression of SLC26A4 gene, by yet to be identified mechanisms, results in the activation of the CXCl1 and CXCl2 chemoattractants and facilitates the infiltration of neutrophils into lungs, resulting in the induction of pulmonary inflammation Nakao et al.
Table 2 Summary of the pulmonary toxicity evaluation findings of crystalline silica exposed rats adapted from Sellamuthu et al. The ARG1 gene which was significantly and progressively overexpressed in the silica-exposed lung samples Table 3 has been found to be associated with bleomycin-induced pulmonary fibrosis in mice Endo et al.
The microarray data have been deposited in the Gene Expression Omnibus Database, http: The significant overexpression of the SLC genes exhibited a steady increase during the post-exposure time intervals Table 3 leey parallel with the progression of pulmonary toxicity noticed in leg silica-exposed rats Table 2 oey, suggesting their potential involvement in the progression of silica-induced pulmonary toxicity.
