Project description:Silica nanoparticles effects on gene expression of A549 cells
2015-08-25 | E-GEOD-53700 | ExpressionAtlas
Project description:We have employed whole genome microarray expression to distinguish the effect of Fumed Silica Nanoparticles on human alveolar epithelial A549 lung cells. Cells were exposed in vitro, and datasets of differentially expressed genes were identified for NPs versus control samples. NPs induced gene expression in A549 cells was measured at 24 hours and 72 hours after exposure. Minimum three independent experiments were performed for each experiment.

Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.

Project description:A proper understanding of the mechanisms underlying crystalline silica-induced pulmonary toxicity has implications in the management and potential prevention of the adverse health effects associated with silica exposure including silicosis, cancer and several auto-immune diseases. Human lung type II epithelial cells and rat lungs exposed to crystalline silica were employed as experimental models to determine global gene expression changes in order to understand the molecular mechanisms underlying silica-induced pulmonary toxicity. The differential gene expression profile induced by silica correlated with its toxicity in the A549 cells. The biological processes perturbed by silica exposure in the A549 cells and rat lungs, as identified by the bioinformatic analysis of the differentially expressed genes, demonstrated significant similarity. Functional categorization of the differentially expressed genes identified cancer, cellular movement, cellular growth and proliferation, cell death, inflammatory response, cell cycle, cellular development, and genetic disorder as top-ranking biological functions perturbed by silica exposure in the A549 cells and rat lungs. The involvement of oxidative stress and apoptosis in the silica-induced pulmonary toxicity was confirmed by ELISA and confocal microscopy analysis, respectively, of the silica-exposed A549 cells. Results of our study, in addition to confirming several previously identified molecular targets and mechanisms involved in silica toxicity, identified novel molecular targets and mechanisms potentially involved in silica-induced pulmonary toxicity. Further investigations, including those focused on the novel molecular targets and mechanisms identified in the current study, may result in a better management and, possibly, reduction and/or prevention of the potential adverse health effects associated with crystalline silica exposure.
